Next, the operation of the hinge for an electronic device and the cellular phone according to the present invention will be described. First, as shown in FIG. 1, in the state in which the transmitter 1 and the receiver 3 are closed, as shown in FIG. 18, the slider cam 7 of the hinge A has a first direction in the left direction in the drawing. The inner cam 10 is moved against the elastic force of the compression spring 9, and the second protruding cam portions 8b and 8b are positioned at the top of one of the outer grooved cam portions 12a of the outer cam 11. The inner cam 10 is locked to the inner protruding cam portion 10a, 10a, and the inner cam 10 is prevented from rotating by engaging the locking portions 14a, 1a of the slider key 14 with the locking grooves 10c, 10c. Therefore, the slider cam 7 is locked at the position moved to the rightmost side. In this state, the conversation part 1 which fixed the outer cam 11 to the mounting part 1a, and the receiving part 3 which fixed the slider cam 7 to the mounting part 3a via the shaft 6 are It is locked in a closed state with each other. Therefore, the inner cam 10, the slider key 14, and the outer cam 11 are composed of the locking means. The locking means may be constituted by providing, for example, a concave-convex engaging means of a known configuration between the sliding cam 22 and the rotary cam 24. On the other hand, in the hinge B, as shown in FIG. 18, the projection 23e of the sliding cam part 23 of the sliding cam 22 and the rotation cam part 25 of the rotating cam 24 are similar. Since the recesses 25a and 25a are in opposite positions, the precushion torque generated by the sliding cam 22 and the rotary cam 24 of the hinge B is weak or almost absent.

In this state, when the supporter 1 is supported on the palm of one left hand and the push button 15 on the hinge B side is pressed with a thumb, the slider key 14 is applied to the elastic force of the second compression spring 16. The inner cam 10 rotates and the inner cam 10 rotates because the locking state of the inner cam 10 which has moved to the right side in the drawing and held by the locking portions 14a and 14a is released. The slider cam 7, which has held the second protruding cam portions 8b and 8b to the inner protruding cam portions 10a and 10a of the first cam, is released as the inner cam 10 rotates. A direction in which the inner cam 10 rotates while being pressed in the left direction by the elastic force of (9) and connected to the first inclined portion 12b of the outer recessed cam portions 12a and 12a provided in the outer cam 11. In the drawing, while moving in the left direction while rotating in the same direction as shown in the drawing, the receiver cam 7, ie the shaft guide 6 in the opening direction in the opening direction 3 Room torque occurs, and that earpiece 3 is from the aspect of automatically carried out with one hand operation is opened up to 90 degrees with respect to the mouthpiece portion (1). At this time, since the pre-cushion torque of the hinge B is hardly generated as described above, it does not become an obstacle when the receiver 3 is automatically opened.

When the hydration section 3 is opened to 90 degrees, as shown in Fig. 19, the protruding cam sections 8a and 8a of the slider cam 7 of the hinge A are the outer recessed cam sections 12a of the outer cam 11. 12a, the projections 25b and 25b of the rotary cam portion 25 of the rotary cam 24 of the hinge B are similarly shown in FIG. Since the colliding portions 23a and 23a of the sliding cam portion 23 of 22 are in contact with each other, the receiver 3 automatically opens and stops at an angle of about 90 degrees with respect to the transmitter 1. At the same time, the first protruding cam portions 8a and 8a of the slider cam 7 fall into the inner grooved cam portion 10d of the inner cam 10 to rotate the inner cam 10 by 180 degrees. The inner cam 10 has a locking portion 14a, 14a of the slider key 14 that returns to its original position when the push button 15 returns to its original position at a position rotated 180 degrees. By engaging with the locking grooves 10c and 10c, it becomes in a non-rotating state, and the inner protruding cam portions 10a and 10a of the inner cam 10 are again the second protruding cam portions 8b and 8b of the slider cam 7. ) Can be locked. At this time, the first protrusion cam portions 8a and 8a of the slider cam 7 fall into the outer recessed cam portions 12a and 12a of the outer cam 11 without the inner cam 10 rotating 180 degrees. When entering, it may be configured to be inverted and returned to its original position.

At this time, the first protruding cam portions 8a and 8a of the slider cam 7 of the hinge A are connected to the inner protruding cam portions 10a and 10a of the inner cam 10 at the time of opening. The sound of "car ??" is generated from the strong force falling into the deepest portions of the outer grooved cam portions 12a and 12a of the outer cam 11 by the elastic force. Then, at the opening angle of 90 degrees, not only the keyboard 2b on the side of the talker 1 can be operated, but also the liquid crystal display 4b on the side of the receiver 3 can be seen. In addition, if the hydration part 3 is to be closed manually from the opening angle, the second protruding cam part 8b, 8b of the slider cam 7 is the inner protruding cam part of the inner cam 10 near the closing position. By passing over (10a, 10a), the? Cracking operation by manual operation is possible. In the closed state, the second protruding cam portions 8b and 8b of the slider cam 7 are locked by being locked by the inner protruding cam portions 10a and 10a of the inner cam 10.

After the receiver 3 is opened up to about 90 degrees with respect to the receiver 1, the hand 3 is pushed in the opening direction with the thumb while also holding the receiver 1 in the left hand grip. The first protruding cam portions 8a, 8a of the slider cam 7 of (A) ride on the other second inclined portion 12c of the outer grooved cam portions 12a, 12a of the outer cam 11, Further, as shown in FIG. 19, the contact position of the protrusions 23a and 23a of the sliding cam portion 23 of the sliding cam 22 of the hinge B is determined by the rotation cam portion 25 of the rotating cam 24.
