(Embodiment)
For example, a sliding portable terminal in which two casings are freely slidable has a shape including a display unit in each of two housings, or a display unit formed by a touch panel that can be operated on the display screen itself. A portable terminal having various specifications such as a shape including Hereinafter, the portable terminal is provided with a display unit on the surface of the casing that is always visible regardless of the slide, and an operation such as numeric buttons is performed on the surface of the casing that is housed by opening and closing, on the side facing the casing including the display unit. A description will be given by taking as an example a type including an operation unit to be performed.

  FIG. 1 is an exploded perspective view showing an example of a sliding portable terminal according to an embodiment of the present invention.

  The mobile terminal 100 includes a first casing 1, a second casing 2, a base member 3, a first drawer slide member 4, a second drawer slide member 5, a front slide member 6, and a built-in antenna (communication antenna). 7 is provided. The base member 3, the first drawer slide member 4, the second drawer slide member 5, and the front slide member 6 are collectively referred to as a slide structure portion 10.

  The first casing 1 includes a display unit and the like on the surface. The first housing 1 is supported by the second housing 2 so as to be linearly slidable by the slide structure unit 10.

  The second casing 2 has a built-in antenna 7 inside the terminal opening direction side tip of the mobile terminal 100. The second housing 2 is a surface on the side facing the back surface of the first housing 1, and an operation unit for performing a function operation or an input operation around the other end on the side not having the built-in antenna 7. Is provided.

  The base member 3 is attached to the surface side of the second housing 2 provided with the operation section and the like so as not to be applied to the built-in antenna 7 of the second housing 2. That is, the arrangement of each part provided in the second casing 2 is in the order of the built-in antenna 7, the base member 3, the operation unit, and the like from the opening direction side of the mobile terminal 100. The first casing 1 and the second casing 2 have the largest overlapping portion so that the rear surface of the first casing 1 and the surface of the second casing 2 including the operation unit are opposed to each other. In addition, the front slide member 6 is attached to the first casing 1. At this time, the slide structure 10 is attached in the most extended state.

  As a method of fixing the slide structure 10 to the first housing 1 and the second housing 2, for example, screw holes are made in each of the base member 3 and the front slide member 6, and the first housing 1 is screwed. And the front slide member 6, the second housing 2 and the base member 3 are fastened. Further, the first casing 1 having the function of the front slide member 6 is formed on the first casing 1 itself, and the second casing 2 having the function of the base member 3 is formed on the second casing 2 itself. It may be a method to do.

  The slide structure unit 10 is in a degenerated state (contracted) when the overlapping portion of the base member 3, the first drawer slide member 4, the second drawer slide member 5, and the front slide member 6 is maximized. It is said to be heavy). For example, the degenerated state (during degeneracy) of the slide structure portion 10 formed in a nested structure is the stored state (during storage). Conversely, when each member is pulled out and the overlapping portion is minimized, it is said to be in an extended state (during extension). When the slide structure 10 is in a degenerated state, the mobile terminal 100 is in an open state, and when the slide structure 10 is in an extended state, the mobile terminal 100 is in a closed state.

  The total length in the sliding direction when the slide structure 10 is extended is shorter than the length of the overlapping portion of the mobile terminal 100 where the overlapping portion of the first casing 1 and the second casing 2 is the largest. That is, the total length when the slide structure 10 is extended is shorter than the lengths in the longitudinal direction of the first casing 1 and the second casing 2. Further, the total length in the sliding direction when the slide structure portion 10 is degenerated is shorter than the length of the overlapping portion of the portable terminal 100 where the overlapping portion of the first casing 1 and the second casing 2 is the smallest. That is, the total length when the slide structure 10 is degenerated is shorter than the length in the sliding direction of the portion where the first casing 1 and the second casing 2 overlap each other.

  Regardless of whether the slide structure portion 10 is extended or degenerated, the slide structure portion 10 is contained within a range of a portion where the first and second housings 1 and 2 face each other. The first is not only in the case of extension and degeneracy, but also in each of the operation states of the degeneracy operation from extension to degeneration and the extension operation from degeneracy to extension. The slide structure portion 10 is housed in a range of a portion where the housing 1 and the second housing 2 face each other and overlap each other. In addition, since the base member 3 portion of the slide structure 10 is attached to a position closer to the mobile terminal 100 closing direction than the built-in antenna 7 of the second housing 2, during extension, degeneration, extension / degeneration operation In all of the states, the slide structure 10 and the built-in antenna 7 do not overlap.

  In the portable terminal 100 of FIG. 1, the case where the communication antenna 7 is provided inside the opening end of the second housing 2 has been described as an example. In the present embodiment, the communication antenna 7 may be located at the tip of the second housing 2 and not on the slide structure 10. Further, the communication antenna 7 is not necessarily built-in, and a part or the whole of the antenna may be provided outside the second housing 2 as long as the position does not cover the slide structure 10.

  FIG. 2 is a perspective view showing the operation of the slide structure. FIG. 2A shows a state when the slide structure 10 is extended, and FIG. 2D shows a state when the slide structure 10 is degenerated. The operating state of the slide structure 10 changes from FIG. 2A toward FIG. 2D or from FIG. 2D toward FIG. 2A. FIG. 2A to FIG. 2D show the degeneracy operation of the slide structure unit 10, and FIG. 2D to FIG. 2A show the extension operation of the slide structure unit 10.

  FIG. 3 is a sectional view of the structure of the slide structure. FIG. 3 is a cross-sectional view taken along line MM in FIG. In order from the inside, the base member 3, the first drawer slide member 4, the second drawer slide member 5, and the front slide member 6 are formed and overlap in a nested structure. The size of each member of the slide structure portion 10 increases from the inside toward the outside, and each member of the slide structure portion 10 is configured to overlap when the slide structure portion 10 is degenerated.

  Further, when the slide structure portion 10 is degenerated, the distal end position of the base member 3 in the direction of degeneracy is the front end position of the first drawer slide member 4, the second drawer slide member 5, and the front slide member 6 in the direction of degeneration. It is configured so that it is located farther than the position, or all the tip positions on the degenerate direction side are the same position.

  First, the degeneracy operation of the slide structure unit 10 will be described. In the state of FIG. 2A, the slide structure 10 is held by stoppers (not shown) provided in each member of the slide structure 10 so that the most slid state can be maintained. When the front slide member 6 is moved toward the degenerative direction from that state, that is, when the front slide member 6 is moved toward the base member 3, the second drawer slide member 5 is accommodated inside the front slide member 6. . FIG. 2B shows a state in which the second drawer slide member 5 is stored up to a stopper provided at the front end of the front slide member 6 in the direction of degeneracy.

  If the front slide member 6 is moved toward the degenerative direction as it is, the first drawer slide member 4 is housed inside the second drawer slide member 5. FIG. 2C shows a state in which the first drawer slide member 4 is stored up to the stopper provided with the second drawer slide member 5. Further, when the front slide member 6 is moved in the direction of degeneracy, the base on the fixed side is moved to the inner side of the first drawer slide member 4 to the stopper provided with the first drawer slide member 4. The member 3 is stored.

  As a result, the second drawer slide member 5, the first drawer slide member 4, and the base member 3 are accommodated in this order inside the front slide member 6, and finally all as shown in FIG. 2 (d). Will be overlapped. A series of flows from FIG. 2A to FIG. 2D is performed as a degenerate operation of the slide structure portion 10.

  FIG. 2D shows an example in which each member of the slide structure portion 10 has the same position in the degenerate direction, but the position of the base member 3 in the degenerate direction is farthest. Just do it.

  The extension operation of the slide structure 10 is performed in the reverse flow to the degeneracy operation. In the state shown in FIG. 2D, the slide structure unit 10 is provided with catches (not shown) provided at the distal ends of the members of the slide structure unit 10 in the extending direction so that the degenerated state can be maintained. Held in. When the front slide member 6 is pulled out from this state, first, the first drawer slide member 4, the second drawer slide member 5, and the front slide member 6 other than the base member 3 on the fixed side are caught until the base member 3 is caught. It moves and it will be in the state of FIG.2 (c).

  When further moved from the state of FIG. 2C, the first drawer slide member 4 is fixed by the catch of the base member 3. And the 2nd drawer slide member 5 and the front slide member 6 move, and it will be in the state of FIG.2 (b). Further, the second drawer slide member 5 is fixed by the catch of the first drawer slide member 4, and only the front slide member 6 is pulled out, and finally the state shown in FIG.

  In the operation of FIG. 2, the slide member is described as being stored or extended in order for easy understanding. The order of storing and extending the slide member is not limited to the example described.

  By providing the slide structure portion 10 with the first drawer slide member 4 and the second drawer slide member 5, it becomes possible to increase the total slide length. Moreover, it becomes possible to make the slide structure part 10 smaller at the time of degeneracy. Furthermore, since the position of the distal end portion on the degenerate direction side of the slide structure portion 10 is not located farther than the distal end on the same side of the base member 3, not only during extension but also during degeneracy, The part covered by the slide structure 10 is easy to understand, and it is possible to design so that unnecessary parts are not covered with a member.

  FIG. 4 is a cross-sectional view showing the operation of the sliding portable terminal. FIG. 5 is a plan view showing the operation of the sliding portable terminal. The operations of the sliding portable terminal shown in FIGS. 4 and 5 correspond to each other, and the operation of the sliding structure portion shown in FIG. Specifically, a cross-sectional view illustrating the operation of the sliding portable terminal in FIG. 4A, a plan view illustrating the operation of the sliding portable terminal in FIG. 5A, and the sliding structure portion in FIG. The sectional view of the configuration is a view in the same operation state.

  When the portable terminal 100 is in the opening operation, the slide structure unit 10 is degenerate. That is, when the portable terminal 100 is closed (FIGS. 4A and 5A), the slide structure 10 is slid maximum (FIG. 2A). When the portable terminal 100 is opened (FIGS. 4D and 5D), the slide structure 10 is folded (FIG. 2D).

  The first casing 1 of the portable terminal 100 includes a display unit 11 and a main function operation button 12 that is a functional part for inputting a function operation command on the surface. The second housing 2 is an input portion 21 that is an input portion for inputting numbers or symbols, and a functional portion for inputting an operation command for a function, on the surface facing the first housing 1. Certain function operation buttons (operation units) 22 and 23 are provided.

  In the state where the portable terminal 100 in FIG. 5A is closed, the display unit 11 of the first casing 1 can be seen. In addition, the main function operation buttons 12 provided near the display unit 11 can be used to answer a phone call, hang up the phone, and turn on / off the main power of the mobile terminal 100 in a closed state. At this time, as can be seen from FIG. 4A, the slide structure 10 is in the most slid state. The closed state of the portable terminal 100 can be fixed and held by a stopper or lock of each member of the slide structure unit 10.

  FIG. 5B shows a state where the mobile terminal 100 is being opened. As can be seen from FIG. 4B, the first drawer body 1 and the second casing 2 are moved by the distance that the second drawer slide member 5 of the slide structure portion 10 is housed in the front slide member 6 and slid at that time. Is displaced and the portable terminal 100 is opened.

  In the state where the mobile terminal 100 of FIG. 5C is half open, in addition to the operation in the state where the mobile terminal 100 of FIG. 5A is closed, the input unit 21 of the second housing 2 is used to make a phone call. You can make a call by entering a number. At this time, as can be seen from FIG. 4C, the second drawer slide member 5 and the first drawer slide member 4 of the slide structure portion 10 are accommodated in the front slide member 6. The state where the portable terminal 100 is half-opened can be fixed and held by a stopper or lock of each member of the slide structure unit 10.

  In the state where the mobile terminal 100 of FIG. 5D is fully opened, the function operation buttons (operation units) 22 and 23 of the second housing 2 can be used, and the operation command operation of the functions of the mobile terminal 100 is possible. It is. For example, making a call using a telephone directory, sending and receiving mail, listening to an answering message, and the like can be mentioned. At this time, as can be seen from FIG. 4D, the second drawer slide member 5, the first drawer slide member 4, and the base member 3 of the slide structure unit 10 are accommodated in the front slide member 6. The state where the mobile terminal 100 is fully opened can be fixed and held by catching the slide structure 10 or the like.

  A stopper, a lock, or a catch is provided so that the operating state of the mobile terminal 100 can be fixed and held during the opening / closing operation of the mobile terminal 100. Also, the state changes between the state in which the mobile terminal 100 in FIG. 5A is closed, the state in which the mobile terminal 100 in FIG. 5C is half-opened, and the state in which the mobile terminal 100 is fully opened in FIG. In the operation to be performed, the stopper, the lock, or the catch of the slide structure portion 10 is designed so that the fixed and held state can be released by applying a little load. It is not always necessary to provide a stopper, a lock, and a catch, and the slide mechanism can be arbitrarily set by using a spring, a rail, a guide, or the like.

  In addition, in the state of the mobile terminal 100 (FIG. 5B) where it is not necessary to fix and hold the state, the slide structure unit 10 is designed so that it can slide smoothly.

  In the above-described example, the mobile terminal 100 is described so as to function in a state where the mobile terminal 100 in FIG. 5C is half opened, but the mobile terminal 100 may function only in a fully opened state. In this case, the slide structure unit 10 is designed so that the mobile terminal 100 can be smoothly slid in the middle state of the opening / closing operation (FIG. 5B and FIG. 5C).

  The position of the slide member 10 in the direction of degeneracy of the base member 3 is farther from the positions of the tips of the first drawer slide member 4, the second drawer slide member 5, and the front slide member 6 in the direction of degeneracy. Or all the degenerate direction side tip positions are configured to be the same position. Therefore, when opening / closing the portable terminal 100, the first drawer slide member 4, the second drawer slide member 5, and the front slide member 6 do not move from the front end position of the base member 3 in the degenerative direction side. Therefore, the slide structure unit 10 does not cover the built-in antenna 7 of the second casing 2 and the deterioration of the antenna performance can be prevented. Moreover, since the slide structure part 10 is comprised by the multistage sheet metal structure which consists of a some member, a slide full length can be enlarged.

  FIG. 6 is a perspective view showing an example of the slide assist structure. The slide structure unit 10 of the mobile terminal 100 includes a slide assist structure 20 that assists the opening / closing operation of the mobile terminal 100, that is, the degeneracy / extension operation of the slide structure unit 10, and functions as a slide urging unit during operation. .

  The slide assist structure 20 includes an assist spring 20a, caulking pins 20b and 20c, and slide rails 20d, 20e, and 20f. The slide rails 20 d and 20 e are formed on the first drawer slide member 4, and the slide rail 20 f is formed on the second drawer slide member 5. The slide rail 20e of the first drawer slide member 4 and the slide rail 20f of the second drawer slide member 5 are arranged so that the rail portions of the slide rails 20e and 20f overlap when the slide structure 10 is degenerated. It is formed.

  The caulking pin 20b is caulked to the sliding structure 10 extending direction side of the base member 3. The assist spring 20a is housed in the base member 3 with the caulking pin 20b as one end. The caulking pin 20 b includes a rod that protrudes from the base member 3 toward the front slide member 6. The rod of the caulking pin 20b is movably supported through the slide rail 20d, and assists the extension / degeneration operation of the base member 3 and the first drawer slide member 4.

  Further, the caulking pin 20 c is caulked to the front slide member 6. The caulking pin 20 c includes a rod that protrudes from the front slide member 6 toward the base member 3. The rod of the caulking pin 20c is supported so as to be movable through the slide rail 20e and the slide rail 20f, and the first drawer slide member 4, the second drawer slide member 5 and the front slide member 6 can be extended and degenerated. Assist. Further, the caulking pin 20c applies to the assist spring 20a a force for compressing the center portion of the assist spring 20a (force acting in the direction of arrow F) when the assist spring 20a moves to a predetermined position.

  When the slide structure 10 is degenerated, the slide rail 20e and the slide rail 20f are gradually overlapped, and the distance between the caulking pin 20c and the assist spring 20a is shortened. When the center portion of the assist spring 20a comes to a predetermined position near the caulking pin 20c, the assist spring 20a is compressed in the direction of arrow F by the caulking pin 20c. When the assist spring 20a central portion passes the caulking pin 20c portion, the assist spring 20a is released from the force applied by the caulking pin 20c. When the assist spring 20a tries to return to its original state from the compressed state, a force acts in the direction opposite to the arrow F, and the slide assisting structure 20 uses the urging force of the assist spring 20a so that the slide assist structure 20 has a slide structure. Ten degenerate operations can be assisted. For the extension operation, the slide structure 10 is slid in the opposite direction to the degeneracy operation. The use of the urging force of the assist spring 20a is performed in the same way during extension / degeneration. As a result, the extension / degeneration operation of the slide structure 10 and the opening / closing operation of the portable terminal 100 can be performed smoothly.

  As described above, in this embodiment, the amount of slide movement when the terminal is opened and closed can be increased, and the antenna performance can be prevented from deteriorating even when the terminal is opened.

  In addition, since the amount of sliding movement of the terminal can be increased, the total length of the mobile terminal with the mobile terminal fully opened is increased, and telephone conversation is facilitated. Further, since the second housing side can be used effectively and many functions such as an operation unit can be mounted, the functions mounted on the first housing can be reduced, and as a result, the display unit can be enlarged. .

  In the present invention, the mobile terminal and the slide structure are not limited to the above examples, and various modifications and applications are possible.

  For example, in the above-described embodiment, two drawer slide members of the slide structure portion are provided. However, at least one drawer member may be provided, and three or more drawer slide members may be provided. Further, for example, the slide structure portion includes a stopper, a lock, and a catch, but a mechanism can be arbitrarily set, such as a spring, a rail, or a guide. Further, the operation mechanism of the slide structure unit may be a mechanism that performs an opening / closing operation by being assisted by the slide assist structure.

  Further, for example, although the antenna is a built-in antenna, it may be attached outside the second housing without being built-in. Further, the display unit of the mobile terminal can be operated by a touch panel, and may be a type that is operated by directly touching with a finger or operated with a touch pen. Furthermore, regarding the arrangement and display method of the display unit, such as having two display units on the two housings of the portable terminal and performing one display by combining the two display units, or performing separate display on each display unit. It can be set arbitrarily.

  The antenna may be an antenna for any application, and may be a television reception, a Felica antenna, or the like in addition to communication. Furthermore, in the above-described embodiment, the mobile terminal is exemplified as a mobile phone, but it is a PHS (Personal Handy-phone System), a PC (Personal Computer), a PDA (Personal Digital Assistant), a mobile tool, an electronic dictionary, or the like. Or infrared communication may be provided.
