[0054] By combining as described above, the connecting unit 5 can smoothly open and close, and a comfortable opening and closing operation on the mobile phone 1 is realized. This opening / closing operation will be described with reference to the longitudinal side views of FIGS.

When the mobile phone 1 is in the closed state, as shown in FIG. 9, the lid 3 and the main body 7 are folded with the open / close inner surface facing each other. At this time, the connecting body 20 includes the lid side unit 5a and the main body. The side unit 5b has advanced to the maximum extent, and the roller 44a of the lid-side pressing unit 40a is in contact with the locking recess 23a, and the roller 44b of the main body side pressing unit 40b is in contact with the locking recess 23b. Therefore, the lid side unit 5a and the connecting body 20 are locked by the pressing force of the lid side pressing unit 40a, and the main body side unit 5b and the connecting body 20 are locked by the pressing force of the main body side pressing unit 40b. It is stable in the closed state.

[0056] When the lid 3 and the main body 7 are opened in a double-spread shape by the user, as shown in Fig. 10, when the roller 44b exceeds a certain force, the biasing force of the coil panel 59b (connecting body) 20), it moves from the locking recess 23b to the arc inner peripheral surface 24b, and is locked and locked by the locking recess 25b. When further opened, it locks by the locking recess 26b. Is done. Accordingly, the arc outer peripheral surface 29b of the coupling body 20 draws an arc along the arc surface 66b of the main body side guide body 60b and slides, so that the coupling body 20 is retracted (retracted) toward the main body 7 side. Become.

In the present embodiment, since the elastic force of the coil panel 59a is configured to be stronger than the elastic force of the coil panel 59b, the state where the roller 44a is locked to the locking recess 23a is maintained on the lid 3 side. It should be noted that the elastic force of the coil panel 59a and the coil panel 59b may have other configurations such as a reverse relationship or the same elastic force.

[0058] When the lid 3 and the main body 7 are further opened by the user, as shown in Fig. 11, one end of the coupling body 20 abuts on the main body side guide cover 80b and further retracts toward the main body 7 side. Can not . Therefore, when the roller 44a on the lid 3 side exceeds a certain force, it moves from the locking recess 23a to the arc inner peripheral surface 24a against the urging force of the coil panel 59a and is locked by the locking recess 25a. The Therefore, the arc outer peripheral surface 29a of the coupling body 20 slides in an arc along the arc surface 66a of the lid side guide body 60a, and the coupling body 20 moves backward toward the lid 3 side. At this time, the mobile phone 1 is stabilized in an open state at an angle of about 160 ° suitable for a call.

[0059] Furthermore, when the lid 3 and the main body 7 are opened to the fully open position by the user, as shown in Fig. 12, the roller 44a exceeds the urging force of the coil panel 59a when a certain force is exceeded. Then, it moves from the locking recess 25a to the locking recess 26a and is locked. Accordingly, the arc outer peripheral surface 29a of the coupling body 20 slides along the arc surface 66a of the lid-side guide body 60a, and the coupling body 20 is retracted to the maximum on the lid portion 3 side. At this time, the lid portion 3 and the main body portion 7 are in a state of being close to each other, and the connecting end surface 6 la of the lid side guide body 60a and the connecting end surface 6 lb of the main body side guide body 60b are in contact with each other.

The one end side of the connecting body 20 is attached to the recess 62a so as to be able to advance and retreat, and the other end side of the connecting body 20 is attached to the recess 62b so as to be able to advance and retract. For this reason, in the fully opened state, the connecting body 20 can be stored in the recesses 62a and 62b and concealed, and the appearance of the mobile phone 1 can be made beautiful.

[0061] In addition, an advancing / retreating guide 68 (68a, 68b) for moving the connecting body 20 back and forth by drawing an arc with the retaining rotation shaft 85 (85a, 85b) as an axis is provided between the lid side unit 5a and the body side unit 5b. By providing the connecting body 20 with the side wall 28 and the arc outer peripheral surface 29 (29a, 29b), the connecting body 20 can be advanced and retracted from the recess 62 (62a, 62b) in an arc shape. For this reason, in the open state, the connecting body 20 is stored in the recess 62, and in the transition from the open state to the closed state, the connecting body 20 also advances in the recess 62 force in an arc shape, and the lid portion 3 and the body portion 7 It can be done at any time if is allowed to close.

[0062] Further, the axis of the arc surface 66a on the lid part 3 side is the lid rotation axis 3 la, and the axis of the arc surface 66b on the body part 7 side is the body rotation axis 31b. By forming the guide 68, it is possible to realize a comfortable opening and closing operation in the fully closed state, the fully open state, and the state between them.

[0063] Further, when the opening / closing angle between the lid 3 and the main body 7 becomes a constant angle, the locking recesses 23 (23a, 23b), 25 ( 25a, 25b), 26 (26a, 26b) and the pressing unit 40 (40a, 40b) are provided. , 90. 160. Further, the lid 3 and the main body 7 can be stabilized at a constant angle such as 180 °, and the operability is improved for the user. The opening / closing angle to be locked is not limited to these, and a locking recess may be formed so as to lock the advancement / retraction at other angles, and the advancement / retraction is locked at other than the fully closed angle and the fully open angle. You can also form a locking recess!

[0064] In addition, since the coil panel 59 (59a, 59b) that applies an urging force to the pressing unit 40 is employed, a force that stabilizes the lid portion 3 and the main body portion 7 at a certain angle is applied to the coil panel 59. It can be easily adjusted by force, and it provides a click feeling opening / closing mechanism. It can be done.

[0065] Further, until the fully open state is also closed (until the fully closed state), the connecting rotary body 85a and 85b is in contact with the shaft contact grooves 21a and 21b, so that the connecting body 20 is covered with the lid. It can be prevented from falling off from the side unit 5a and the main body side unit 5b.

The force may be adjusted to an appropriate strength. As a result, the lid unit 5a and the main unit 5b move forward and backward in a symmetrical manner with respect to the connecting body 20, or cause the mobile phone 1 to perform a desired opening and closing operation, such as moving forward and backward independently. be able to.

Further, the locking recesses 23, 25, and 26 may be provided on the inner surface of the side wall 28 without being provided on the slide plate 27. In this case, the roller 44 may be formed of, for example, a sphere and urged outward in the width direction so as to be locked to a locking recess provided on the inner surface of the side wall 28. Even with this configuration, the mobile phone 1 can be positioned at a predetermined opening / closing angle, and an appropriate click feeling can be obtained.

The roller 44 may be configured to be non-rotating with a slippery shape or material. Even in this case, the opening / closing operation can be performed smoothly and the opening / closing angle can be locked.

[0072] Further, in the fully opened state, the connection body 20 is concealed so that it cannot be completely seen. For example, a hole is provided on the connection side of the lid side guide cover 80a and the main body side guide cover 80b, You may comprise so that the connection body 20 can visually recognize a part even in a fully open state. Even in this case, it is possible to provide the mobile phone 1 with a smart design that does not make it possible to see a rugged hinge as it is.
