Description

  The present invention relates to a conveyance device that nipping and conveying a sheet by a roller pair.

  Some conveying apparatuses are configured such that the sheet conveyed by the roller pair is discharged into a space communicating with the outside through an opening formed in the front surface of the apparatus. Further, the conveying device includes one of the rollers constituting the roller pair in order to facilitate the so-called jam processing, which is a process of taking out a sheet jammed in the conveying path while being sandwiched between the roller pairs from the outside through the opening. Some of them are separated from the other, or the nip pressure of the roller pair is reduced.

  Patent Document 1 discloses an image forming apparatus in which an operation lever is rotated to release a pressure state of a roller pair so that a sheet jammed while being held between the roller pair can be easily taken out.

JP-A-4-140248

  However, in the image forming apparatus disclosed in Patent Document 1, the following problem occurs when the image forming process is started without returning the roller pair to the pressure state after taking out the jammed sheet. In other words, in this case, even if a sheet placed in the cassette is fed to the conveyance path by the pickup roller, the sheet is not pinched by the roller pair, so that the sheet may be jammed in the conveyance path.

  In order to solve such a problem, it is considered that the image forming apparatus is configured so that the user can easily grasp the pressure state of the roller pair by providing a sensor for detecting the position of the operation lever. It is done. However, adding a sensor increases the cost of the device.

  The present invention has been made in view of the above problems, and its object is to provide a sheet supported by a feeding tray in a state in which the pressure is released when the pressure of the roller pair is released when a jam occurs. It is to provide a means that can prevent the feeding of the paper.

  (1) A conveying apparatus according to the present invention includes a feeding tray that supports a sheet, and a feeding roller that feeds the sheet supported by the feeding tray, and the feeding roller and the feeding roller A feeding unit capable of changing state to a contact state in which the sheet supported by the feeding tray is in contact, and a separated state in which the feeding roller and the sheet supported by the feeding tray are separated from each other; and a first roller And a pair of rollers that sandwich and convey the sheet fed by the feeding roller by a second roller facing the first roller, wherein the first roller presses the second roller. A pair of rollers capable of changing state to a second state in which the pressing force of the first roller against the second roller is smaller than that in the first state, and a first position where the roller pair is in the first state; The roller pair is in the second state. A movable member movable between two positions, and the feeding unit is changed from the contact state to the separated state in conjunction with the movement of the movable member from the first position to the second position. An interlocking mechanism.

  According to this configuration, when the movable member is operated and moved from the first position to the second position when a jam occurs, the feeding unit changes its state from the contact state to the separated state by the interlocking mechanism. When the movable member moves to the second position, the state of the roller pair changes from the first state to the second state, so that the sheet sandwiched between the roller pair can be easily taken out.

  When the movable member is in the second position, the feeding unit is in a separated state. Thereby, even if the feeding roller rotates while the movable member is in the second position, the sheet supported by the feeding tray is not fed. As a result, it is possible to prevent the sheet from being jammed inside the apparatus when the sheet is fed while the roller pair is in the second state.

  (2) The feeding tray can be pulled out of the housing of the apparatus. The interlocking mechanism moves the feed tray from the feeding position where the sheet is fed by the feeding roller in a pulling direction in conjunction with the movement of the movable member from the first position to the second position. In conjunction with the movement in the pull-out direction, the feeding unit is changed from the contact state to the separated state.

  According to this configuration, when the movable member is operated to move from the first position to the second position when a jam occurs, the feeding tray is moved in the pull-out direction by the interlocking mechanism. Then, due to the movement in the drawing direction, the feeding unit changes from the contact state to the separated state. As a result, the same effect as the above (1) can be obtained.

  Further, when the feeding unit is in the separated state, the feeding tray is a position slightly pulled out from the housing. For this reason, the user can easily recognize that the feeding unit is in the separated state by visually checking the state of the feeding tray.

  (3) The feeding unit includes an arm that is provided above the feeding tray, the feeding roller is rotatably disposed at one end, and is rotatable about the other end. The arm has a first posture in which the feeding portion is brought into the abutting state, and a second end in which the one end portion is located above the first posture and the feeding portion is placed in the separated state. It can be rotated to the posture. The interlocking mechanism is provided on the feeding tray, and abuts on the arm in the process of moving from the feeding position in the pulling direction to rotate the arm from the first posture to the second posture. A guide is provided.

  According to this configuration, when the movable member is operated to move from the first position to the second position when a jam occurs, the feeding tray is moved in the pull-out direction by the interlocking mechanism. When the feeding tray moves in the pulling direction, the arm is rotated from the first posture to the second posture by the guide portion. Thereby, the state of the feeding unit can be changed from the contact state to the separated state.

  (4) The interlocking mechanism moves the movable member from the second position to the first position in conjunction with the movement from the state in which the feeding tray is pulled out to the feeding position. In conjunction with the movement from the second position to the first position, the state of the feeding unit is changed from the separated state to the contact state.

  According to this configuration, the movable member is moved from the second position to the first position by pushing the feeding tray drawn from the feeding position into the feeding position by moving the movable member from the first position to the second position. By moving to the position, the state of the feeding unit can be changed from the separated state to the contact state. That is, by moving the feeding tray to the feeding position, the movable member can be automatically moved to the first position, and the feeding unit can be automatically changed to the contact state.

  (5) The interlocking mechanism includes a contacted portion provided on the feeding tray, a contact portion provided on the movable member and capable of contacting the contacted portion from the upstream side in the pulling direction, Is provided. The position of the contact portion at which the movable member is in the second position is on the downstream side in the pulling direction from the position of the contact portion at which the movable member is in the first position. The feeding tray moves in the pull-out direction when the contacted portion is pushed by the contact portion due to the movement of the movable member from the first position to the second position.

  According to this configuration, when the movable member moves from the first position to the second position, the contact portion provided on the movable member pushes the contacted portion provided on the feeding tray from the upstream side in the pull-out direction. As a result, the feeding tray moves in the pulling direction. Then, the movement can change the state of the feeding unit from the contact state to the separated state. That is, the interlocking mechanism can be realized with a simple configuration.

  Further, when the feeding tray moved in the pulling direction by being pushed by the abutting portion is pushed into the feeding position, the abutted portion pushes the abutting portion from the downstream side in the pulling direction. Thereby, the movable member can be moved from the second position to the first position.

  Further, when the user grips the feeding tray and pulls it out from the feeding position, the movable member does not move. Therefore, the feeding tray can be moved independently without moving the movable member.

  (6) The feeding unit includes an arm that is provided above the feeding tray, the feeding roller is rotatably disposed at one end, and is rotatable about the other end. The arm has a first posture in which the feeding portion is brought into the abutting state, and a second end in which the one end portion is located above the first posture and the feeding portion is placed in the separated state. It can be rotated to the posture. The interlocking mechanism rotates the arm from the first posture to the second posture in conjunction with the movement of the movable member from the first position to the second position.

  According to this configuration, when the movable member is operated to move from the first position to the second position when a jam occurs, the arm rotates from the first posture to the second posture by the interlocking mechanism. Thereby, the state of the feeding unit can be changed from the contact state to the separated state.

  (7) When the roller pair is in the second state, the first roller may be separated from the second roller.

  (8) A conveying device according to the present invention includes a feeding tray that supports a sheet, and a feeding roller that feeds the sheet supported by the feeding tray, and the feeding roller and the feeding roller. A feeding unit capable of changing state to a contact state in which the sheet supported by the feeding tray is in contact, and a separated state in which the feeding roller and the sheet supported by the feeding tray are separated from each other; and a first roller And a pair of rollers that sandwich and convey the sheet fed by the feeding roller by a second roller facing the first roller, wherein the first roller presses the second roller. , And a roller pair capable of changing the state to a second state in which the pressing force of the first roller against the second roller is smaller than that in the first state, and the roller pair from the first state to the second state. In conjunction with the state change of the above feeding The may be one and a linkage mechanism for a state change to the separation state from the contact state.

  According to the present invention, when the roller pair is in the second state, the feeding unit is in the separated state. Therefore, when the roller pair is in the second state when jamming occurs and the pressure between the rollers is released, it is possible to prevent the sheet supported by the feeding tray from being fed while the pressure is released. .

The opening 91 is connected to the inclined surface 97 whose front side is higher than the rear side, the horizontal surface 98A connected to the front end of the inclined surface 97 and extending in the front-rear direction 8, and the rear end of the inclined surface 97. 8 and a horizontal plane 98 </ b> B extending to 8. In addition, the opening 92 is connected to the inclined surface 99 whose front side is higher than the rear side, the horizontal surface 100A connected to the front end of the inclined surface 99 and extending in the front-rear direction 8, and the rear end of the inclined surface 99. And a horizontal plane 100 </ b> B extending in the front-rear direction 8.

  Hereinafter, the state change of the conveyance roller pair 59 accompanying the movement of the lever unit 90 will be described. As shown in FIGS. 3A and 5A, when the lever portion 90 is located at the first position, the shaft 54 is located below the horizontal plane 98A in the opening 91. At this time, the pinch roller 61 is pressed against the conveying roller 60 by the urging force of the elastic member 66 (see FIG. 4). That is, the conveyance roller pair 59 is in the first state.

  When the user grips the grip portion 93 and pulls the lever portion 90 forward, the lever portion 90 moves forward from the first position. As a result, the shaft 54 contacts the inclined surface 97. When the lever portion 90 moves further forward, the shaft 54 moves relative to the inclined surface 97 while sliding. As a result, the shaft 54 is guided by the inclined surface 97 and moves downward.

  Then, the shaft 54 comes into contact with the lower end of the inner peripheral surface constituting the hole 53B of the convex portion 52B and pushes the lower end. Thereby, the support member 55 integrally formed with the convex portion 52B and the pinch roller 61B supported by the support member 55 move downward. As a result, the pinch roller 61B is separated from the transport roller 60. On the other hand, at this time, the support member 55 integrally formed with the convex portion 52A and the pinch roller 61A supported by the support member 55 do not move.

  When the lever 90 moves further forward in a state where the pinch roller 61B is separated from the conveying roller 60, the shaft 54 moves further downward. Then, as shown in FIG. 5B, the shaft 54 abuts against the lower end of the inner peripheral surface constituting the hole 53A of the convex portion 52A and pushes the lower end. Thereby, the support member 55 integrally formed with the convex portion 52A and the pinch roller 61A supported by the support member 55 move downward. As a result, as shown in FIG. 5C, the pinch roller 61 </ b> A is separated from the conveyance roller 60. That is, the transport roller pair 59 is in the second state.

  In FIG. 5C, the interval between the pinch roller 61A and the conveying roller 60 is larger than the interval between the pinch roller 61B and the conveying roller 60. This is because the pinch roller 61B starts to move downward before the pinch roller 61A.

  Thereafter, when the lever portion 90 moves further forward, the shaft 54 comes into pressure contact with the horizontal plane 98B by the urging force of the elastic member 66 as shown in FIG. At this time, the lever part 90 has reached the second position. That is, when the lever portion 90 is in the second position, the transport roller pair 59 is in the second state.

  Hereinafter, the state change of the discharge roller pair 44 accompanying the movement of the lever portion 90 will be described. As shown in FIG. 3A, when the lever portion 90 is located at the first position, the shaft 64 of the discharge roller 62 is located below the horizontal plane 100 </ b> A in the opening 92. At this time, the discharge roller 62 is pressed against the spur 63 by the urging force of an elastic member (not shown). That is, the discharge roller pair 44 is in the first state.

  When the user grips the grip portion 93 and pulls the lever portion 90 forward, the lever portion 90 moves forward from the first position. As a result, the shaft 64 contacts the inclined surface 99. When the lever portion 90 moves further forward, the shaft 64 moves relative to the inclined surface 99 while sliding. As a result, the shaft 64 moves downward. That is, the discharge roller 62 moves downward. As a result, the discharge roller 62 is guided by the inclined surface 99 and moves downward, and is separated from the spur 63. That is, the discharge roller pair 44 is in the second state.

  Thereafter, when the lever portion 90 moves further forward, the shaft 64 comes into pressure contact with the horizontal surface 100B by the urging force of the elastic member, as shown in FIG. 3B. At this time, the lever part 90 has reached the second position. That is, when the lever portion 90 is in the second position, the discharge roller pair 44 is in the second state.

  When the lever portion 90 moves from the second position to the first position, an operation opposite to that described above is performed. That is, when the shaft 54 is separated from the horizontal plane 98 </ b> B and slides on the inclined surface 97, the pinch roller 61 moves upward and comes into contact with the transport roller 60. Further, when the shaft 64 is separated from the horizontal plane 100B and slides on the inclined surface 99, the discharge roller 62 moves upward and comes into contact with the spur 63.

  As described above, the lever 90 is in the first position where the transport roller pair 59 and the discharge roller pair 44 are in the first state, and in the second position where the transport roller pair 59 and the discharge roller pair 44 are in the second state. It can be moved between.

[Interlock mechanism 85]
The interlocking mechanism 85 is a mechanism that changes the state of the feeding unit 16 from the contact state to the separated state in conjunction with an operation of moving the lever portion 90 from the first position to the second position. The interlocking mechanism 85 includes an inclined surface 71 (an example of the guide portion of the present invention, see FIG. 8) and a contacted portion 86 (see FIGS. 2A and 8) provided on the feeding tray 20, a lever portion. 90 and a contact portion 87 (see FIG. 2).

[Inclined surface 71]
As shown in FIG. 8, on the upper surface of one side plate 30 of the pair of side plates 30 (right side in the present embodiment), a horizontal plane 70 extending forward from the rear end of the side plate 30 and a front diagonal from the horizontal plane 70. An inclined surface 71 inclined downward is provided. The position of the inclined surface 71 in the front-rear direction 8 is behind the roller 72 described later when the feeding tray 20 is located at the feeding position that is the position shown in FIG. Here, the feeding position is a position where the feeding tray 20 is mounted on the housing 14 and is a position where the recording paper 12 supported by the bottom plate 22 is fed to the conveyance path 65. When the feeding tray 20 is positioned at the feeding position, the inclined surface 71 does not necessarily have to be behind the roller 72 described later, and the rear end of the inclined surface 71 is from the roller 72 described later. May be on the rear side.

  The feeding roller 25 is disposed at a position in contact with the center portion of the bottom plate 22 of the feeding tray 20 in the left-right direction 9. Further, the feeding arm 26 extends from the feeding roller 25 diagonally to the upper right. Further, the feeding arm 26 and the support shaft 28 extend from the central portion of the printer unit 11 in the left-right direction 9 to the right end (the same position as the side plate 30 in the left-right direction 9). The feeding arm 26 includes a roller 72 at the lower end of the right end portion. The roller 72 is rotatably supported by the main body of the feeding arm 26.

  Hereinafter, the operation of the feeding unit 16 when the feeding tray 20 is pulled forward from the feeding position will be described. As shown in FIGS. 2A, 8, and 9 </ b> A, when the feeding tray 20 is located at the feeding position, the tip of the feeding arm 26 rotates downward due to its own weight. It is moving. At this time, the feeding arm 26 is in the first posture, and the feeding roller 25 contacts the recording paper 12 supported by the feeding tray 20. At this time, the roller 72 is separated from the inclined surface 71 as shown in FIG.

  When the user grips the grip portion 32 (see FIG. 1) provided on the front plate 31 of the feeding tray 20 and pulls the feeding tray 20 forward, as shown in FIG. The surface 71 contacts the roller 72. When the feeding tray 20 is further pulled forward, the roller 72 slides relative to the inclined surface 71 along the inclined surface 71. As a result, the roller 72 moves upward, and the feeding arm 26 that supports the roller 72 rotates upward. That is, the feeding arm 26 rotates from the first posture to the second posture. The feed roller 25 moves upward by the upward rotation of the feed arm 26. As a result, the feeding roller 25 is separated from the recording paper 12. In addition, the roller 72 is finally separated from the inclined surface 71 and contacts the horizontal surface 70 as shown in FIG. 9C.

  As described above, the inclined surface 71 rotates the feeding arm 26 from the first posture to the second posture by abutting and guiding the feeding arm 26 in the process in which the feeding tray 20 moves forward from the feeding position. In addition, the feeding unit 16 is changed from the contact state to the separated state.

  The feeding arm 26 may not be provided with the roller 72, and the main body of the feeding arm 26 may abut on the inclined surface 71. In this case, when the user pulls the feeding tray 20 forward, the inclined surface 71 comes into contact with the main body. When the feeding tray 20 is further pulled forward, the main body slides relative to the inclined surface 71 along the inclined surface 71. As a result, the feeding arm 26 rotates upward.

[Abutted portion 86 and abutting portion 87]
As shown in FIGS. 2 and 8, the contacted portion 86 is a protrusion protruding upward from the rear end portion and the left and right end portions of the upper surface of the discharge tray 21 provided in the feeding tray 20. The abutted portions 86 are provided on the left and right ends of the upper surface of the discharge tray 21, that is, outside the left and right ends of the recording sheet 12 when the maximum size recording sheet 12 capable of image recording is discharged. Thus, the abutted portion 86 does not prevent the recording paper 12 from being discharged onto the discharge tray 21.

  As shown in FIG. 2, the abutment portion 87 is a protrusion that protrudes downward from the connection portion 94 of the lever portion 90. The position of the contact part 87 in the left-right direction 9 is a position where at least a part of the contact part 87 overlaps with the contacted part 86. The position of the contact portion 87 in the front-rear direction 8 is behind the contacted portion 86. The position of the contact portion 87 when the lever portion 90 is in the second position (see FIG. 2B) is the position of the contact portion 87 when the lever portion 90 is in the first position (see FIG. 2A). It is on the downstream side, that is, the front side.

  When the contacted portion 86 is provided at a position where there is no possibility of contact with the discharged recording paper 12, for example, on the rear side of the discharge roller pair 44, the contacted portion 86 is provided on the feeding tray 20. It is not necessary to be provided at the left and right ends. In this case, the contact portion 87 is disposed in the guide portion 95 of the lever portion 90.

  Hereinafter, the movement of the feeding tray 20 and the state change of the feeding unit 16 accompanying the movement of the lever unit 90 will be described. As shown in FIG. 3 (A), when the lever portion 90 is located at the first position, as shown in FIGS. 2 (A) and 8, the feeding tray 20 is at the feeding position. The feeding unit 16 is in a contact state, and the conveyance roller pair 59 and the discharge roller 44 are in the first state. When the user grips the grip portion 93 and pulls the lever portion 90 forward, the lever portion 90 moves forward from the first position. As a result, the conveyance roller pair 59 and the discharge roller 44 change from the first state to the second state. As a result, the abutting portion 87 also moves forward, abuts against the abutted portion 86 of the feeding tray 20 from the upstream side in the drawing direction of the feeding tray 20, that is, from the rear side. push. Thereby, the feeding tray 20 moves forward and is positioned in front of the feeding position. That is, as shown in FIG. 7, the feeding tray 20 is in a state in which the front end portion thereof is pulled out from the housing 14.

  As described above, the feeding tray 20 moves forward when the contacted portion 86 is pushed by the contact portion 87 by the movement of the lever portion 90 from the first position to the second position.

  When the feeding tray 20 moves forward from the feeding position, the feeding arm 26 rotates from the first posture to the second posture by the roller 72 being in contact with the inclined surface 71 and being guided as described above. At the same time, the feeding unit 16 changes from the contact state to the separated state.

  As described above, the interlocking mechanism 85 moves the feeding tray 20 forward from the feeding position in conjunction with the operation of moving the lever portion 90 from the first position to the second position, and interlocks with the forward movement. Thus, the state of the feeding unit 16 is changed from the contact state to the separated state.

  When the feeding tray 20 is pushed by the user in a state where the front end portion of the feeding tray 20 is pulled out from the housing 14 by the movement of the lever portion 90 from the first position to the second position (see FIG. 7). When moved rearward, the contacted portion 86 pushes the contact portion 87. Thereby, the lever part 90 moves from a 2nd position to a 1st position. As a result, the conveyance roller pair 59 and the discharge roller 44 change from the second state to the first state. Further, when the feeding tray 20 moves rearward, the roller 72 is separated from the horizontal plane 70 and is in contact with the inclined surface 71 to be guided. As a result, the feeding arm 26 rotates from the second posture to the first posture, and the state of the feeding portion 16 changes from the separated state to the contact state.

  In other words, the interlocking mechanism 85 moves the lever portion 90 from the second position to the first position in conjunction with the movement from the state where the feeding tray 20 is pulled out to the feeding position, so that the second position of the lever portion 90 is reached. In conjunction with the movement from the first position to the first position, the state of the feeding unit 16 is changed from the separated state to the contact state.

  In the present embodiment, when the user holds the feeding tray 20 at the feeding position and pulls it forward, the contacted portion 86 is separated from the contact portion 87, so the lever portion 90 does not move.

[Effect of the embodiment]
According to the present embodiment, when the lever portion 90 is operated to move from the first position to the second position when a jam occurs, the feeding mechanism 16 changes from the contact state to the separated state by the interlocking mechanism 85. When the lever portion 90 moves to the second position, the state of the transport roller pair 59 and the discharge roller pair 44 changes from the first state to the second state, so the recording held between the transport roller pair 59 and the discharge roller pair 44 The paper 12 can be easily taken out.

  When the lever portion 90 is in the second position, the feeding portion 16 is in a separated state. Thus, even if the feeding roller 25 rotates while the lever portion 90 is in the second position, the recording paper 12 supported by the feeding tray 20 is not fed to the conveyance path 65. As a result, it is possible to prevent the recording paper 12 from being jammed in the transport path 65 by feeding the recording paper 12 to the transport path 65 in a state where the transport roller pair 59 and the discharge roller pair 44 are in the second state.

  Further, according to the present embodiment, when the lever portion 90 is operated to move from the first position to the second position when a jam occurs, the feeding tray 20 is moved forward by the interlocking mechanism 85. Then, due to the forward movement, the feeding unit 16 changes from the contact state to the separated state. As a result, it is possible to prevent the recording paper 12 from being jammed in the transport path 65 by transporting the recording paper 12 to the transport path 65 with the transport roller pair 59 and the discharge roller pair 44 being in the second state.

  When the feeding unit 16 is in the separated state, the feeding tray 20 is slightly pulled out of the housing 14 as shown in FIG. For this reason, the user can easily recognize that the feeding unit 16 is in the separated state by visually recognizing the state of the feeding tray 20.

  Further, according to the present embodiment, when the lever portion 90 is operated to move from the first position to the second position when a jam occurs, the feeding tray 20 is moved forward by the interlocking mechanism 85. When the feeding tray 20 moves forward, the feeding arm 26 is rotated from the first posture to the second posture by the inclined surface 71. Thereby, the state of the feeding unit 16 can be changed from the contact state to the separated state.

  Further, according to the present embodiment, the lever portion 90 is pushed by pushing the feeding tray 20 pulled out from the feeding position into the feeding position by moving the lever portion 90 from the first position to the second position. By moving from the second position to the first position, the feeding section 16 can be changed from the separated state to the contact state. That is, by moving the feeding tray 20 to the feeding position, the lever portion 90 can be automatically moved to the first position, and the state of the feeding portion 16 can be automatically changed to the contact state.

  Further, according to the present embodiment, when the lever portion 90 moves from the first position to the second position, the contact portion 87 provided on the lever portion 90 is provided on the feeding tray 20. Press from the rear. As a result, the feeding tray 20 moves forward. Then, the movement can change the state of the feeding unit 16 from the contact state to the separated state. That is, the interlocking mechanism 85 can be realized with a simple configuration.

  Further, according to the present embodiment, when the feeding tray 20 moved forward from the feeding position by being pushed by the abutting portion 87 is pushed into the feeding position, the abutted portion 86 causes the abutting portion 87 to be moved. Press from the front. Thereby, the lever part 90 can be moved from a 2nd position to a 1st position.

  Further, according to the present embodiment, when the user holds the feeding tray 20 and pulls it out from the feeding position, the lever portion 90 does not move. Therefore, the feeding tray 20 can be moved independently without moving the lever portion 90.

[Modification 1]
In the above-described embodiment, the interlocking mechanism 85 includes the contacted portion 86, the contact portion 87, and the inclined surface 71. However, the interlocking mechanism 85 is interlocked with an operation of moving the lever portion 90 from the first position to the second position. As long as the feeding arm 26 can be rotated from the first posture to the second posture, the configuration is not limited to the above. For example, the interlocking mechanism 85 may be a link mechanism that connects the lever portion 90 and the feeding arm 26 by connecting one end to the lever portion 90 and the other end to the feeding arm 26 from above. . In the case of this example, when the lever portion 90 moves from the first position to the second position, the feeding arm 26 is pulled upward by the link mechanism, thereby rotating from the first posture to the second posture. That is, it is not necessary to move the feeding tray 20 in order to rotate the feeding arm 26. As described above, in the first modification, the interlocking mechanism 85 rotates the feeding arm 26 from the first posture to the second posture in conjunction with the movement of the lever portion 90 from the first position to the second position.

  According to the first modification, when the lever portion 90 is operated to move from the first position to the second position when a jam occurs, the feeding arm 26 is rotated from the first posture to the second posture by the interlocking mechanism 85. Thereby, the state of the feeding unit 16 can be changed from the contact state to the separated state.

[Modification 2]
In the above-described embodiment, the interlocking mechanism 85 includes the contacted portion 86 and the contact portion 87. However, in conjunction with the operation of moving the lever portion 90 from the first position to the second position, feeding is performed. The configuration is not limited to the above as long as the tray 20 can be moved forward from the feeding position. For example, the interlock mechanism 85 includes a link mechanism that connects the lever portion 90 and the feeding tray 20 with one end connected to the lever portion 90 and the other end connected to the feeding tray 20, and an inclined surface 71. There may be. In the case of this example, when the lever portion 90 moves from the first position to the second position, the feeding tray 20 moves forward from the feeding position by being pulled forward by the link mechanism. Then, the roller 72 is guided in contact with the inclined surface 71 by the forward movement of the feeding tray 20, whereby the feeding arm 26 rotates from the first posture to the second posture, and the feeding unit 16. Changes from a contact state to a separated state.

[Modification 3]
In the above-described embodiment, the feeding unit 16 is configured to change between the contact state and the separated state when the feeding arm 26 rotates, but the configuration is not limited thereto.

  For example, as shown in FIG. 10, the feeding portion 16 is provided on the inner side in the left-right direction 9 with respect to the pair of guide portions 95 of the lever portion 90, and can be rotated to the rear portion of the bottom plate 22 of the feeding tray 20. A rotating plate 79 that can support the rear side portion of the recording paper 12 supported by the bottom plate 22, a coil spring 82 that urges the rotating plate 79 upward, and a feeding tray 20 that is in a feeding position. In this case, the feeding roller 25 provided at a position above the rotating plate 79 may be provided, while the feeding arm 26 may not be provided.

  In the above configuration, the rotation plate 79 is shown in FIG. 10A, and a feeding posture for feeding the recording paper 12 supported by the bottom plate 22 and the rotation plate 79 to the conveyance path 65, and FIG. 10 (B), the recording paper 12 supported by the bottom plate 22 and the rotating plate 79 is rotated between a non-feeding posture in which the recording paper 12 is not fed to the transport path 65. Since the rotation plate 79 in the non-feeding posture is rotated downward relative to the rotation plate 79 in the feeding posture, the recording paper 12 supported by the rotation plate 79 is separated from the feeding roller 25. . That is, when the rotating plate 79 is in the non-feeding posture, the feeding unit 16 is in a separated state. On the other hand, the rotating plate 79 in the feeding posture is biased by the coil spring 82 so that its rotating tip is located above the non-feeding posture, so that the recording supported by the rotating plate 79 is supported. The sheet 12 contacts the feeding roller 25. That is, when the rotating plate 79 is in the feeding posture, the feeding unit 16 is in a contact state.

  The interlocking mechanism 85 in Modification 3 includes a lower surface 83 at the rear end portion of the pair of guide portions 95 and a protrusion 84 that protrudes outward from the left and right ends of the rotating plate 79 and contacts the lower surface 83. Yes. The lower surface 83 is connected to the inclined surface 88 whose front side is higher than the rear side, the horizontal surface 89A connected to the front end of the inclined surface 88 and extending in the front-rear direction 8, and the rear end of the inclined surface 88. And a horizontal plane 89 </ b> B extending to 8.

  When the lever portion 90 is positioned at the first position, the protrusion 84 is pressed against the horizontal plane 89A by being biased by the coil spring 82, as shown in FIG. When the user pulls the lever portion 90 forward, the lever portion 90 moves forward from the first position. Accordingly, as shown in FIG. 10B, the protrusion 84 abuts on the inclined surface 88 and is guided downward by the inclined surface 88. As a result, the rotating plate 79 rotates from the feeding posture to the non-feeding posture against the urging force of the coil spring 82. That is, in conjunction with the movement of the lever portion 90 from the first position to the second position, the feeding portion 16 changes from the contact state to the separated state.

[Modification 4]
In the above-described embodiment, the movable member of the present invention is the lever portion 90 that is gripped and operated by the user, but the movable member of the present invention may not be gripped and operated by the user. . For example, the movable member of the present invention may be a guide portion 95 that is obtained by removing the grip portion 93 and the connection portion 94 from the lever portion 90, that is, the guide portion 95 that is not gripped by the user. In this case, the guide unit 95 is not gripped and operated by the user, but moves in the front-rear direction 8 with a driving force applied from, for example, a motor. The abutting portion 87 is disposed on the guide portion 95 and can abut on the abutted portion 86 from the rear side. When the guide portion 95 driven by the motor moves from the first position to the second position, the abutting portion 87 pushes the abutted portion 86 from the rear side, whereby the feeding tray 20 moves forward.

[Modification 5]
In the above-described embodiment, the transport device includes the lever portion 90, but may not include the lever portion 90. In this case, for example, the interlocking mechanism 85 provided in the transport device protrudes forward from the support member 55 and moves up and down integrally with the support member 55 as shown in FIG. And a second convex member 102 protruding rearward from the rear surface of the discharge tray 21 provided on the feeding tray 20. The second convex member 102 is provided below the first convex member 101 in the vertical direction 7. The upper surface of the second convex member 102 is an inclined surface 103 that is inclined so that the protruding distal end side (rear side) is located below the protruding proximal end side (front side).

  As a result, when the support member 55 moves downward and the conveyance roller pair 59 changes from the first state to the second state, the first convex member 101 that moves downward integrally with the support member 55 becomes the second convex member. It is guided to the inclined surface 103 of 102. Thereby, the second convex member 102 is pushed by the first convex member 101. As a result, the feeding tray 20 moves forward. That is, the interlocking mechanism 85 moves the feeding tray 20 forward in conjunction with the state change of the transport roller pair 59 from the first state to the second state. Then, similarly to the above-described embodiment, when the feeding tray 20 moves forward, the feeding unit 16 changes from the contact state to the separated state. In Modification 5, the support member 55 is moved up and down by applying a driving force from a motor.
