The printer 1 can print on a recording medium P such as a recording sheet with ink, which is an example of a liquid.

  In FIG. 1, XYZ axes which are coordinate axes orthogonal to each other are added. The XYZ axes are also attached to the figures shown below as needed. In this embodiment, the printer 1 is in use when the printer 1 is arranged on a horizontal plane (XY plane) defined by the X axis and the Y axis. The posture of the printer 1 when the printer 1 is arranged on the XY plane is called the use posture of the printer 1. The Z axis is an axis orthogonal to the horizontal plane. In the usage state of the printer 1, the Z-axis direction is the vertically upward direction. In the usage state of the printer 1, the −Z axis direction is the vertically downward direction in FIG. 1. In each of the XYZ axes, the arrow direction indicates the + (positive) direction, and the direction opposite to the arrow direction indicates the- (negative) direction.

  The printer 1 is provided with a paper discharge unit 11. In the printer 1, the recording medium P is ejected from the paper ejection unit 11. In the printer 1, the surface on which the paper discharge unit 11 is provided is the front surface 13. In the present embodiment, the front surface 13 of the printer 1 is also the front surface 13 of the housing 2. The housing 2 has an upper surface 15 that intersects the front surface 13 and a side wall 17 that intersects the front surface 13 and the upper surface 15. When the front surface 13 is viewed from the front, that is, when the front surface 13 is viewed in the −Y axis direction, the side wall 17 is located in the X axis direction of the front surface 13. The housing 2 has a side wall 19 which intersects the front surface 13 and the upper surface 15 and is located in the −X axis direction of the side wall 17 with the front surface 13 interposed therebetween.

  The operation panel 3 is arranged on the front surface 13 of the printer 1. The operation panel 3 is provided outside the housing 2. The outer surface of the operation panel 3 faces the Y-axis direction. When the operation panel 3 is viewed from the front, that is, when the operation panel 3 is viewed in the −Y axis direction, the tank unit 5 is located between the operation panel 3 and the side wall 17. From another point of view, when the printer 1 is viewed from the front, that is, when the printer 1 is viewed in the −Y axis direction, the tank unit 5 is located between the paper discharge unit 11 and the side wall 17.

  A window 21 is provided on the front surface 13 of the housing 2. When the operation panel 3 is viewed from the front, that is, when the operation panel 3 is viewed in the −Y axis direction, the window portion 21 is located between the operation panel 3 and the side wall 17. In this embodiment, the window 21 is provided for each tank 6. When the operation panel 3 is viewed from the front, that is, when the operation panel 3 is viewed in the −Y axis direction, the window portion 21 is provided at a position overlapping the tank 6. In this embodiment, the window portion 21 faces the Y-axis direction.

  The window portion 21 has translucency. Therefore, the user can visually recognize the four tanks 6 through the window portion 21. In the present embodiment, the window portion 21 is made of a translucent member. The user can visually recognize the four tanks 6 through the window portion 21 formed of a translucent member. The window portion 21 need only be translucent and may or may not be transparent. Further, the window portion 21 is not limited to a translucent member, and may be, for example, an opening formed in the housing 2.

  In the present embodiment, at least a part of the portion of each tank 6 facing the window portion 21 has translucency. The ink in the tank 6 can be visually recognized from the translucent portion of each tank 6. Therefore, the user can visually recognize the amount of ink in each tank 6 by visually observing the four tanks 6 through the window portion 21. That is, in the tank 6, at least a part of the portion facing the window portion 21 can be utilized as a visual recognition portion capable of visually recognizing the amount of ink.

  The housing 2 has a cover 23. The cover 23 constitutes a part of the housing 2. When the operation panel 3 is viewed from the front, that is, when the operation panel 3 is viewed in the −Y axis direction, the cover 23 is located between the operation panel 3 and the side wall 17. When the operation panel 3 is viewed from the front, that is, when the operation panel 3 is viewed in the −Y axis direction, the cover 23 is provided at a position overlapping the tank unit 5. The position of the tank unit 5 and the position of the cover 23 in the printer 1 may also be the position between the operation panel 3 and the side wall 19 when the operation panel 3 is viewed from the front.

  The cover 23 is arranged on the front surface 13 of the printer 1. The outer surface of the cover 23 faces the Y-axis direction. As described above, the outer surface of the operation panel 3 also faces the Y-axis direction. In this embodiment, the outer surface of the cover 23 and the outer surface of the operation panel 3 are located in a common plane. In other words, in the use posture of the printer 1, the position of the outer surface of the cover 23 in the Y-axis direction is the same as the position of the outer surface of the operation panel 3 in the Y-axis direction. For this reason, since the outer surface of the cover 23 and the outer surface of the operation panel 3 are located in a common plane, the appearance of the printer 1 is unlikely to be uneven. For this reason, it is difficult for the printer 1 to come into contact with, get caught in, or hit the articles or structures arranged in the surrounding environment when the printer 1 is transported. It should be noted that being in a plane is not limited to conforming to a completely plane, and also includes being in a plane that includes unevenness due to an error, a tolerance, or the like, or a step such as a joint between components.

  Further, in this embodiment, the outer surface of the front surface 13 of the housing 2 also faces the Y-axis direction. In this embodiment, the outer surface of the front surface 13 of the housing 2 and the outer surface of the operation panel 3 are located in a common plane. In other words, in the use posture of the printer 1, the position of the outer surface of the front surface 13 of the housing 2 in the Y-axis direction is the same as the position of the outer surface of the operation panel 3 in the Y-axis direction. For this reason, since the outer surface of the front surface 13 of the housing 2 and the outer surface of the operation panel 3 are located in a common plane, the appearance of the printer 1 is unlikely to be uneven. For this reason, it is difficult for the printer 1 to come into contact with, get caught in, or hit the articles or structures arranged in the surrounding environment when the printer 1 is transported. It should be noted that being in a plane is not limited to conforming to a completely plane, and also includes being in a plane that includes unevenness due to an error, a tolerance, or the like, or a step such as a joint between components.

  A structure capable of adjusting the inclination of the operation panel 3 (also referred to as tilt adjustment) may be adopted. If the tilt of the operation panel 3 can be adjusted, the user can view and operate the operation panel 3 at a desired tilt, which is highly convenient. In the configuration in which the inclination of the operation panel 3 can be adjusted, the outer surface of the cover 23 and the outer surface of the operation panel 3 are common when the operation panel 3 is closed, that is, when the outer surface of the operation panel 3 is orthogonal to the XY plane. Located in the plane.

  The cover 23 covers at least a part of the tank 6. The cover 23 can be opened and closed with respect to the housing 2. When the cover 23 is opened with respect to the housing 2, a part of each tank 6 is exposed. The user can inject ink into each tank 6 with the cover 23 opened with respect to the housing 2. In addition, in the present embodiment, the window portion 21 is provided in the cover 23.

  As shown in FIG. 2, the printer 1 has a recording head 31 and a control unit 32. In the printer 1, the recording head 31 and the control unit 32 are housed in the housing 2. Therefore, in this embodiment, the recording head 31 and the tank unit 5 are housed in the same housing 2. That is, the housing 2 collectively covers the recording head 31 and the tank unit 5. Here, in the configuration in which the tank unit 5 is arranged outside the housing 2, since the mounting of the housing 2 to the printer 1 and the mounting of the tank unit 5 to the housing 2 are separate steps, the assemblability is improved. Easy to fall. On the other hand, in the present embodiment, since the housing 2 is configured to cover the recording head 31 and the tank unit 5 at once, by mounting the housing 2, the recording head 31 and the tank unit 5 are attached. Since the and can be collectively covered with the housing 2, it is easy to improve the assemblability.

  The recording head 31 is an example of a liquid ejecting head, and ejects ink as ink droplets to perform recording on the recording medium P. The recording head 31 performs recording with ink, which is an example of a liquid, on the recording medium P that is conveyed in the Y-axis direction by a conveying device (not shown). A transport device (not shown) transports the recording medium P such as recording paper in the Y-axis direction intermittently. The recording head 31 is configured to be reciprocally movable along the X axis by a moving device (not shown). The controller 32 controls the driving of each of the above components. In this embodiment, four tanks 6 are arranged along the X axis.

  Here, the direction along the X-axis is not limited to the direction completely parallel to the X-axis, and includes the direction inclined due to error or tolerance except the direction orthogonal to the X-axis. Similarly, the direction along the Y axis is not limited to the direction that is completely parallel to the Y axis, and includes the direction inclined due to error or tolerance except the direction orthogonal to the Y axis. The direction along the Z-axis is not limited to the direction completely parallel to the Z-axis, and includes directions tilted due to errors or tolerances, except for the direction orthogonal to the Z-axis. In other words, the direction along any axis or surface is not limited to the direction that is completely parallel to these arbitrary axes or surfaces, and is subject to error, tolerance, etc., except for the direction orthogonal to these arbitrary axes or surfaces. Including the tilted direction.

  In this embodiment, the plurality of tanks 6 are configured separately from each other. However, the configuration of the tank 6, which is an example of the liquid container, is not limited to this. As a configuration of the liquid container, a configuration in which a plurality of tanks 6 are integrated into one liquid container may be adopted. In this case, one liquid container is provided with a plurality of liquid containers. The plurality of liquid storage sections are partitioned from each other and are configured to be capable of storing different types of liquid. In this case, for example, different color inks can be individually stored in the plurality of liquid storage portions.

  Ink, which is an example of a liquid, is stored in the tank 6. A liquid injection port 33 is formed in the tank 6. In the tank 6, ink can be injected from the outside of the tank 6 into the inside of the tank 6 via the liquid injection port 33. A configuration in which the liquid injection port 33 is sealed with a cap (not shown) can also be adopted. When injecting the ink into the tank 6, the user can inject the ink after opening the cap and opening the liquid injection port 33.

  In the present embodiment, the liquid injection port 33 is configured as an opening formed on the outer surface 34 that forms the outer shape of the tank 6. In this embodiment, the outer surface 34 is inclined in the use posture of the printer 1. The outer shape surface 34 is inclined in a direction toward the −Y axis direction from the −Z axis direction toward the Z axis direction. Therefore, the outer surface 34 is oriented in a direction intersecting the vertical direction. The outer surface 34 is an example of an end surface of the liquid injection port 33. If the outer surface 34 is oriented in a direction intersecting the vertical direction, foreign matter such as dust is unlikely to be deposited on the outer surface 34. Therefore, foreign matter such as dust is unlikely to adhere to the outer surface 34. This makes it easy to avoid foreign matter such as dust from entering the liquid injection port 33.

  The configuration of the tank 6 is not limited to the above. As the configuration of the tank 6, for example, as shown in FIG. 3, a configuration in which a tubular liquid injecting portion 35 protruding from the outer surface of the tank 6 is provided may be adopted. In this case, the liquid injection port 33 is opened in the end surface 36 of the tip end of the tubular liquid injection portion 35 protruding from the outer surface of the tank 6 opposite to the tank 6 side. Also in this configuration, the configuration in which the end face 36 is inclined is preferable from the viewpoint that foreign matter such as dust is unlikely to adhere.

  As shown in FIG. 2, an ink supply tube 37 is connected to each tank 6. The ink in the tank 6 is supplied to the recording head 31 via the ink supply tube 37. Then, the ink supplied to the recording head 31 is ejected as an ink droplet from a nozzle (not shown) directed to the recording medium P side.

  Although the tank unit 5 has been described as one of the components of the printer 1 in the above example, the tank unit 5 and the printer 1 may be configured separately from each other. When the tank unit 5 and the printer 1 are configured separately from each other, the tank unit 5 is arranged outside the housing 2. That is, when the tank unit 5 and the printer 1 are configured separately from each other, the tank unit 5 is not covered by the housing 2. When the tank unit 5 and the printer 1 are configured separately from each other, for example, the tank unit 5 is housed in a housing different from the housing 2, and the housing housing the tank unit 5 is coupled to the housing 2. Can be considered. As a method of connecting the housing housing the tank unit 5 and the housing 2, various connection methods such as a screw connection and a fitting connection can be considered.

  The tank 6 may also have a configuration in which an upper limit mark 42, a lower limit mark 43, etc. are added to a visible surface 41 that allows the amount of ink contained to be visually recognized. The user can grasp the amount of ink in the tank 6 by using the upper limit mark 42 and the lower limit mark 43 as marks. The upper limit mark 42 indicates a standard of the ink amount so that the ink does not overflow from the liquid injection part 35 when the ink is injected from the liquid injection part 35. Further, the lower limit mark 43 indicates the standard of the ink amount when the ink injection is prompted. A configuration in which at least one of the upper limit mark 42 and the lower limit mark 43 is provided on the tank 6 can also be adopted. The visible surface 41 faces the Y-axis direction.

  In the printer 1 having the above configuration, the recording medium P is conveyed in the Y-axis direction, and the recording head 31 ejects ink droplets at a predetermined position while reciprocating the recording head 31 along the X-axis. Recording is performed on the recording medium P. These operations are controlled by the control unit 32.

  The ink is not limited to either the water-based ink or the oil-based ink. The aqueous ink may be either an ink having a constitution in which a solute such as a dye is dissolved in an aqueous solvent or an ink having a constitution in which a dispersoid such as a pigment is dispersed in an aqueous dispersion medium. Further, the oil-based ink may be either one having a constitution in which a solute such as a dye is dissolved in an oil-based solvent or one having a constitution in which a dispersoid such as a pigment is dispersed in an oil-based dispersion medium.

  As shown in FIG. 4, the cover 23 is configured to be rotatable with respect to the housing 2 in the R1 direction in the drawing. The R1 direction corresponds to a counterclockwise direction when the YZ plane is viewed in plan from the X-axis direction with the axis along the X-axis as the rotation axis. The cover 23 can be opened with respect to the housing 2 by rotating the cover 23 in the R1 direction with respect to the housing 2. A state in which the cover 23 is opened with respect to the housing 2 is referred to as an open state of the cover 23. The cover 23 can be closed with respect to the housing 2 by rotating the cover 23 in the direction opposite to the R1 direction from the open state of the cover 23. As described above, in the present embodiment, the cover 23 is configured to be openable and closable with respect to the housing 2. A state in which the cover 23 is closed with respect to the housing 2 is referred to as a closed state of the cover 23.

  The appearance of the printer 1 is not limited to the texture and colors shown in FIG. As the external appearance of the printer 1, for example, a printer whose surface is embossed may be used.

  The direction in which the cover 23 is opened with respect to the housing 2 is not limited to the R1 direction. With respect to the direction in which the cover 23 is opened with respect to the housing 2, the rotation axis along the X-axis is positioned at the end of the cover 23 in the Z-axis direction, and the clockwise direction is obtained when the YZ plane is viewed in plan from the X-axis direction. Directions can also be adopted. Further, as a direction in which the cover 23 is opened with respect to the housing 2, the rotation axis along the Z-axis is located at the end of the cover 23 in the X-axis direction, and the XY plane is viewed in plan from the Z-axis direction. A clockwise direction may also be adopted. Further, as a direction of opening the cover 23 with respect to the housing 2, when the rotation axis along the Z axis is positioned at the end portion of the cover 23 in the −X axis direction and the XY plane is viewed in plan from the Z axis direction. A clockwise direction may also be adopted.

  When the cover 23 is opened, the liquid injection port 33 of the tank 6 is exposed. Therefore, the user can access the liquid injection port 33 of the tank 6 from the outside of the housing 2. Then, in the open state of the cover 23, the user can inject the ink contained in the bottle 47 or the like into the tank 6 from the liquid injection port 33. At this time, the user can inject the ink into the liquid injection port 33 while checking the amount of the ink in the tank 6 through the visual check surface 41.

  At this time, if the horizontal state of the printer 1 is deviated, the amount of ink in the tank 6 visually recognized through the viewing surface 41 may lack accuracy. This is because if the horizontal state is displaced, the position of the ink surface with respect to the visible surface 41 is displaced. When such a situation occurs, when the ink is being injected into the liquid injection port 33, the ink is likely to be injected to the extent that the ink overflows from the liquid injection port 33. Further, when the printer 1 is used and the horizontal state of the printer 1 is deviated when the cover 23 is closed, the amount of ink in the tank 6 visually recognized through the window 21 may lack accuracy. is there. When this occurs, it is possible that ink is not supplied to the recording head 31 even though the amount of ink in the tank 6 exceeds the lower limit mark 43 (FIG. 2).

  In the present embodiment, information indicating the horizontal state of the printer 1 is displayed on the display panel 8. In other words, the display panel 8 can display the horizontal state of the printer 1. As the information displayed on the display panel 8, for example, as shown in FIG. 5, an indicator 51 for instructing the horizontal state of the printer 1 is compared with a sight line 52 which is a position when the printer 1 is horizontal. Information is given.

  The user can recognize the horizontal state of the printer 1 based on the information indicating the horizontal state displayed on the display panel 8. When the horizontal state of the printer 1 is deviated, the user can adjust the horizontal state of the printer 1 so that the indicator 51 displayed on the display panel 8 approaches the sight line 52. As a result, it is easy to avoid the situation where the ink overflows from the liquid injection port 33 while the ink is being injected into the liquid injection port 33, and the situation where the ink is not supplied to the recording head 31.

  Further, in the printer 1, as shown in FIG. 4, the housing 2 has a cover 61 and a cover 62. Each of the cover 61 and the cover 62 constitutes a part of the housing 2.

The R2 direction corresponds to a clockwise direction when the YZ plane is viewed in plan from the X axis direction with the axis along the X axis as the rotation axis. By rotating the cover 61 in the R2 direction with respect to the housing 2, the cover 61 can be opened with respect to the housing 2. The cover 61 can be closed with respect to the housing 2 by rotating the cover 61 in the direction opposite to the R2 direction from the open state of the cover 61. As described above, in this embodiment, the cover 61 is configured to be openable and closable with respect to the housing 2.

  The cover 62 is configured to be rotatable in the R3 direction in the figure. The R3 direction corresponds to the clockwise direction when the YZ plane is viewed in plan from the X axis direction with the axis along the X axis as the rotation axis. The cover 62 can be opened with respect to the housing 2 by rotating the cover 62 in the R3 direction with respect to the housing 2. The cover 62 can be closed with respect to the housing 2 by rotating the cover 62 in the direction opposite to the R3 direction from the opened state. As described above, in this embodiment, the cover 62 is configured to be openable and closable with respect to the housing 2.

  When the cover 61 is opened with respect to the housing 2, the paper feeding section 63 is exposed. The recording medium P can be supplied to the printer 1 from the paper feeding unit 63. When the recording medium P is supplied from the paper feeding unit 63 to the printer 1, the recording medium P can be supported by the cover 61. That is, in the present embodiment, the cover 61 includes a paper support function.
