The groove plate part 141 includes a first slide groove plate 32, a second slide groove plate 34, and a pressing plate 36. Each plate 32, 34, 36 has the same size as seen from the Z-axis direction.

  The first slide groove plate 32 is formed with a substantially U-shaped (U-shaped) through groove 32a. Specifically, the through groove 32a includes Y groove portions 132a and 132b extending in the Y-axis direction, and an X groove portion 132c that connects the + Y ends of the Y groove portions 132a and 132b. That is, it can be said that the through-groove 32a has a changing portion whose extending direction changes at a position where the Y groove portion 132a and the X groove portion 132c intersect and a position where the Y groove portion 132b and the X groove portion 132c intersect.

The second slide groove plate 34 is formed with a substantially U-shaped (U-shaped) through groove 34 a as a groove portion. The through groove 34 a has substantially the same shape as the through groove 32 a of the first slide groove plate 32. That is, the through groove 34a includes Y groove portions 134a and 134b extending in the Y-axis direction, and an X groove portion 134c that connects the + Y end portions of the Y groove portions 134a and 134b. The through groove 34a is slightly wider than the through groove 32b as a whole. In Figure 4, as specific dimensions, Y groove 134a, the width in the X-axis direction 134b as x _1, has a width in the Y-axis direction of the X groove 134c and y _1. In addition, it can be said that this through-groove 34a also has two change parts where the extending direction of the groove changes between one end and the other end.

In the through groove 36a, the width in the X-axis direction of the portion extending in the Y-axis direction matches the width in the Y-axis direction of the portion extending in the X-axis direction. In addition, it can be said that this penetration groove | channel 36a also has two change parts from which an extending direction of a groove | channel changes between one end and the other end.

The engaging member 16 includes a rectangular plate-shaped plate member 39 and a wiring through member 40. The plate member 39 has a width in the X-axis direction of x ₁ and a width in the Y-axis direction of y ₁ . FIG. 5A shows a cross-sectional view of the engaging member 16. As shown in FIG. 5A, the wiring through member 40 has a ring-shaped flange portion 40 a and a cylindrical portion 40 b, and the cylindrical portion 40 b is inserted into a through hole 39 a formed in the plate member 39. It is in a state. The flange portion 40a has a diameter that does not allow the through groove 36a formed in the pressing plate 36 of FIG. 4 to pass, and the cylindrical portion 40b has a diameter that can pass through the through groove 36a. As shown in FIG. 5A, the wiring through member 40 is formed with a through hole 41 penetrating in the Z-axis direction.

  FIG. 5B is a cross-sectional view showing a state in which the first slide groove plate 32, the second slide groove plate 34, the pressing plate 36, and the engagement member 16 are assembled. As shown in FIG. 5B, the engaging member 16 is sandwiched between the first slide groove plate 32 and the pressing plate 36. In this state, the engaging member 16 can slide along the through groove 34a without being detached from the through groove 34a of the second slide groove plate 34. Further, the wiring through member 40 slides along the through groove 36 a formed in the pressing plate 36 when sliding along the through groove 34 a of the engaging member 16.

  Returning to FIG. 4, the spring 18 is a torsion spring, and its one end 18 a is rotatably joined to the wiring through member 40 via the shaft 99 from the + Z side of the pressing plate 36, and the other end. 18b is rotatably joined to a shaft 36b provided at a substantially central portion of the + Z side surface of the pressing plate 36.

  In the slide module 14 configured as described above, as shown in FIG. 5C, the pressing plate 36 is fixed to the upper body 10, and the engagement member 16 is fixed to the lower body 20 at a fixed position 20 a (FIG. a))) and is fixed (caulking, etc.). As a result, the slide module 14 is assembled to the mobile terminal 100. At the time of this assembly, the wiring 42 for connecting the display 30 of the upper body 10 and an electronic component such as a circuit board provided in the lower body 20 is connected to the wiring as shown in FIG. It passes through the through hole 41 of the member 40. Further, as shown in FIG. 6, the wiring 42 is fixed using a fixing member (fixing tape or the like) 46 at a position near the one end 18 a and a position near the other end 18 b from the center of the spring 18.

  Returning to FIG. 3A, the lower body 20 includes an input key 20b and an input mechanism 20c which is an input interface different from the input key 20b. As the input key 20b, for example, a QWERTY keyboard or the like can be adopted. As the input mechanism 20c, for example, a pointing device such as a track pad or a device for fingerprint authentication can be employed.

  Next, the movement of the slide module 14 when the upper body 10 and the lower body 20 transition as shown in FIGS. 2A to 2D will be described with reference to FIGS. explain. FIGS. 7A to 7C are views showing the movement of the slide module 14 when the state of FIG. 2A is changed to the state of FIG. 2B.

  As shown in FIG. 7A, in the state where the upper body 10 and the lower body 20 are closed (the state shown in FIG. 2A), the engaging member 16 has the + X end portion and the + Y end portion of the upper body 10. It is located near the part. In this case, the spring 18 imparts an elastic force in the direction of opening the spring 18 to the upper body 10 and the lower body 20. This elastic force becomes a force (-Fy) for urging the upper body 10 in the -Y direction and a force (-Fx) for urging the upper body 10 in the -X direction. Among these, since the movement of the engaging member 16 is restricted by the action of the force (−Fy), in the portable terminal 100, the state of FIG. 7A is maintained unless an external force acts on the bodies 10 and 20. Will be.

  When the human force (+ Fhy) is applied from the state of FIG. 7A and the state of FIG. 7B is changed to the state of FIG. 7C (the state of FIG. 2B), the second slide The upper body 10 moves in the + Y direction while the engaging groove 16 and the through groove 34a formed in the groove plate 34 are engaged. In this case, as shown in FIG. 7B, the spring 18 has a force (−) in the direction in which the bodies 10 and 20 overlap until the one end 18a and the other end 18b of the spring 18 are aligned in the X-axis direction. Fy (FIG. 7A)) is continuously urged between the bodies 10 and 20. On the other hand, as shown in FIG. 7C, when the upper body 10 moves in the + Y direction as compared with FIG. 7B, the spring 18 applies a force (+ Fy) in the direction of separating the bodies 10 and 20. The body 10 and 20 are energized. In the state of FIG. 7C, the movement of the engaging member 16 is restricted by the action of the force (+ Fy). Thereby, in the portable terminal 100, the state shown in FIG. 7C is maintained unless an external force is applied to the bodies 10 and 20.

  Thus, when the upper body 10 is slid in the + Y direction, the spring 18 generates a force that resists the pressing force (+ Fhy) until the person presses the upper body 10 for a certain amount or more. Then, after the person presses the upper body 10 for a certain amount or more, the spring 18 generates a force in the same direction as the pressing force (+ Fhy). That is, the elastic force of the spring 18 enhances the feeling of human operation when the upper body 10 is shifted in the + Y direction.

  FIGS. 8A to 8C are views showing the movement of the slide module 14 when the state of FIG. 2A is changed to the state of FIG.

  As shown in FIG. 8A, human force (+ Fhx) is applied from the state in which the upper body 10 and the lower body 20 are closed (the state in FIG. 2A), and the state in FIG. When the state transitions to the state shown in FIG. 8C (the state shown in FIG. 2C), the upper body 10 is engaged while the through groove 34a formed in the second slide groove plate 34 and the engaging member 16 are engaged. Moves in the + X direction. In this case, as shown in FIG. 8B, the spring 18 has a force (−) in the direction in which the bodies 10 and 20 overlap until the one end 18a and the other end 18b of the spring 18 are aligned in the Y-axis direction. Fx (FIG. 8A)) is continuously urged between the bodies 10 and 20. On the other hand, when the upper body 10 moves in the + X direction as compared with FIG. 8B, the spring 18 applies a force (+ Fx) in the direction of separating the bodies 10 and 20 as shown in FIG. 8C. It is urged between the bodies 10 and 20. In the state of FIG. 8C, the movement of the engaging member 16 is restricted by the action of the force (+ Fx). Thereby, in the portable terminal 100, unless an external force acts on the bodies 10 and 20, the state of FIG.

  Thus, when the upper body 10 is slid in the + X direction, the spring 18 generates a force that resists the pressing force (+ Fhx) until the person presses the upper body 10 for a certain amount or more. Then, after the person presses the upper body 10 for a certain amount or more, the spring 18 generates a force in the same direction as the pressing force (+ Fhx). That is, the elastic force of the spring 18 enhances the feeling of human operation when the upper body 10 is shifted in the + X direction.

  FIGS. 9A to 9C are views showing the movement of the slide module 14 when the state of FIG. 2C is changed to the state of FIG. 2D.

  As shown in FIG. 9A, a human force (+ Fhy) is applied from a state where the upper body 10 is displaced in the + X direction with respect to the lower body 20 (state shown in FIG. 2C). 9) through the state of FIG. 9C (the state of FIG. 2D), the through groove 34a formed in the second slide groove plate 34 and the engaging member 16 are engaged. The upper body 10 moves in the + Y direction. In this case, as shown in FIG. 9B, the spring 18 has a force (−) in the direction in which the bodies 10 and 20 overlap until the one end 18a and the other end 18b of the spring 18 are aligned in the X-axis direction. Fy (FIG. 9A) continues to be urged between the bodies 10 and 20. On the other hand, when the upper body 10 moves in the + Y direction from FIG. c), the force (+ Fy) in the direction of separating the bodies 10 and 20 is urged between the bodies 10 and 20. In the state of FIG. The movement of the joint member 16 is restricted, whereby in the portable terminal 100, the state of FIG.9 (c) is maintained unless an external force acts on the bodies 10,20.

  Thus, when the upper body 10 is slid in the + Y direction, the spring 18 generates a force that resists the pressing force (+ Fhy) until the person presses the upper body 10 for a certain amount or more. Then, after the person presses the upper body 10 for a certain amount or more, the spring 18 generates a force in the same direction as the pressing force (+ Fhy). That is, the elastic force of the spring 18 also enhances the feeling of human operation when the upper body 10 is shifted in the + Y direction as shown in FIGS. 9 (a) to 9 (c).

  Next, a guide mechanism provided on the upper body 10 and the lower body 20 for translating the upper body 10 relative to the lower body 20 will be described with reference to FIGS. 10 (a) to 10 (f). To do.

  As shown in FIG. 10A, on the + Z side surface of the lower body 20, a Y-axis concave guide 52a extending in the Y-axis direction, an X-axis concave guide 52b extending in the X-axis direction, and an X-axis direction An extending X-axis convex guide 52c is provided. Further, as shown in FIG. 10B, on the −Z side surface of the upper body 10, a Y-axis convex guide 54a extending in the Y-axis direction, an X-axis convex guide 54b extending in the X-axis direction, and an X-axis An X-axis concave guide 54c extending in the direction is provided.

  According to these guides, when the bodies 10 and 20 are closed as shown in FIG. 2 (a), the X-axis concave guide 52b and the X-axis convex guide 54b are engaged as shown in FIG. 10 (c). The X-axis convex guide 52c and the X-axis concave guide 54c are engaged. Further, as shown in FIG. 10E, the Y-axis concave guide 52a and the Y-axis convex guide 54a are engaged.

  On the other hand, when the state of FIG. 2 (a) is changed to the state of FIG. 2 (b), the engagement of the guides 52a and 54a is maintained as shown in FIG. Further, the guide 52b and the guide 54b are separated from each other, and the guide 52c and the guide 54c are separated from each other.

  Furthermore, when the state of FIG. 2 (a) transitions to the state of FIG. 2 (c), the engagement between the guide 52b and the guide 54b and the guide 52c and the guide 54c is maintained as shown in FIG. 10 (c). As shown in FIG. 10F, the guides 52a and 54a are separated from each other.

  Thus, by providing each guide, it is possible to suppress rotation of the upper body 10 relative to the lower body 20 when the upper body 10 slides in the X-axis direction and when it slides in the Y-axis direction.

  When the state of FIG. 2C is changed to the state of FIG. 2D, the guides do not come into contact with each other. As a result, each guide does not interfere with the relative movement of the upper body 10 and the lower body 20 when transitioning to the state of FIG.

  As described above in detail, according to the present embodiment, the upper body 10 has a through groove having two changing portions between the one end portion and the other end portion on the −Z side surface. The lower body 20 has an engaging member 16 that engages with the through groove 34a and can slide along the through groove 34a on the surface on the + Z side. Further, when the engaging member 16 is positioned at one end, the other end, and the changing portion of the through groove 34a, a spring 18 that applies a biasing force in a direction that restricts the movement of the engaging member 16 is the engaging member. 16 and the upper body 10 are connected. Therefore, in the present embodiment, the relative configuration between the upper body 10 and the lower body 20 is based on the shape of the through groove 34a having two changing portions with a simple configuration of the through groove 34a, the engaging member 16, and the spring 18. Movement can be realized. That is, it is possible to realize a mobile terminal capable of various slide deformations with a simple configuration. As described above, since various slide deformations are possible, for example, by providing an input mechanism 20c or the like in a part of the lower body 20 exposed when deformed as shown in FIG. The function of the terminal 100 can be expanded.

  Furthermore, unlike the prior art, slides in the X-axis and Y-axis directions are not realized by connecting slide mechanisms for each axis in series, so that it is easy to ensure the rigidity of the mechanism. Furthermore, since the through-groove 34a and the like, the engaging member 16, and the spring 18 have a simple configuration, it is possible to reduce the size and weight of the mobile terminal 100 and facilitate the mechanical design.

  Further, in the present embodiment, the spring 18 has one end 18 a rotatably joined to the engaging member 16 via the shaft 99 and the other end 18 b joined rotatably to the shaft 36 b of the upper body 10. The spring 18 is always urged in the direction in which the distance between the joint portion of the engaging member 16 and the joint portion of the upper body 10 is increased. In the present embodiment, by providing one spring as described above, the biasing force in a direction that restricts the movement of the engaging member 16 when positioned at one end, the other end, and the changing portion of the through groove 34a. Can be generated in the spring.

  In the present embodiment, the engagement member 16 is formed with a through hole 41 through which the wiring 42 that electrically connects the upper body 10 and the lower body 20 is passed. That is, the wiring 42 connects the upper body 10 and the lower body 20 through the engaging member 16. Thereby, since the wiring 42 moves in conjunction with the movement of the upper body 10 and the lower body 20, it is possible to suppress the wiring 42 from hindering the sliding of the engaging member 16. Further, damage to the wiring 42 can be suppressed. Further, by passing the wiring 42 through the engaging member 16, the waterproof function can be easily mounted.

  In the present embodiment, the wiring 42 is fixed at a position near the one end 18 a and a position near the other end 18 b from the center of the spring 18. For this reason, even if the spring 18 rotates in the XY plane when the engaging member 16 slides along the through groove 34 a, the wiring 42 rotates together with the spring 18. Thereby, since mechanical interference between the spring 18 and the wiring 42 can be suppressed, the sliding movement with respect to the lower body 20 of the upper body 10 can be performed smoothly.

  In the present embodiment, the −Z side surface of the upper body 10 and the + Z side surface of the lower body 20 are provided with guide mechanisms (guides 52 a, 52 b, 52 c) that suppress the rotation of the upper body 10 during sliding movement. , 54a, 54b, 54c). Thereby, it is possible to suppress the twist between the bodies 10 and 20 while the upper body 10 is being slid. Thereby, the lifetime of the portable terminal 100 can be extended.

  In the above embodiment, the case where the upper body 10 and the lower body 20 are electrically connected by the wiring 42 has been described. However, the present invention is not limited to this. For example, it is possible to electrically connect wirelessly. In this case, a slide module 14 ′ as shown in FIG. 11 can be adopted as the slide module. The slide module 14 'includes a first slide groove plate 32, a second slide groove plate 34, an engagement member 16', and a spring (not shown). The engaging member 16 ′ is obtained by omitting the wiring through member 40 from the engaging member 16 of the above-described embodiment, and is fixed to the lower body 20 (fixed by caulking). In this way, when wireless is employed, a simple configuration can be employed as the slide module 14 '.

  In the above embodiment, a guide mechanism (guides 52a, 52b, 52c, 54a, 54b, 54c) is employed as a mechanism for suppressing the twisting between the upper body 10 and the lower body 20 during sliding. explained. However, the present invention is not limited to this, and a retracting mechanism 60 as shown in FIG. 12 can also be adopted.

  As shown in FIG. 12A, the retracting mechanism 60 includes a permanent magnet 70 provided at the −X side and −Y side end of the upper body 10, and a −X side and −Y side end of the lower body 20. And a permanent magnet 74 provided substantially at the center in the X-axis direction of the −Y side end of the lower body 20. Magnetic attraction is generated between the permanent magnet 70 and the permanent magnet 72 and between the permanent magnet 70 and the permanent magnet 74. Examples of the material of the permanent magnets 70, 72, and 74 include Nd—Fe—B and Sm—Co.

  According to the retracting mechanism 60, when the upper body 10 is slightly displaced in the + Y direction from the lower body 20, as shown in FIG. A force to return to the closed state acts between the lower body 20 and the lower body 20. 12B, even when the upper body 10 is slightly displaced from the lower body 20 in the + X direction, the upper body 10 and the lower body 20 are caused by the permanent magnet 70 and the permanent magnet 72. In between, a force to return to the closed state acts.

  Also, as shown in FIG. 12C, when the upper body 10 is slightly displaced in the −X direction from the lower body 20 with respect to the state of FIG. 2C, the permanent magnet 70 and the permanent magnet 74 A force is applied between the upper body 10 and the lower body 20 to return to the state shown in FIG.
