Description of the invention (5) '~~ ---- Abundant sadness. This holding force φ surplus is generated by the axial force of the coil spring 31 relative to the outer ring & 铨 1β 疋 relative to the rotational resistance of the coil spring 16. When the communication unit 2 and the answering unit 3 are opened, the housing "= 9, the stator unit 12 and the external cam 16 will rotate relative to each other, and the watch ^^ 疋 is in a connected state, so it is connected with the stator unit 12 — ： 17 will be pushed towards the right of each other: 2: 2 in the picture. Then use an opening angle of about ι0 degrees to make the inner, 7: axially move to the outside of the clutch that can be released "and the clutch of 28 a (the clutch unit 26 is in an off state). . In this way, the rotational force of the torsion coil spring 32 that often acts on the inner rotor 17 is released. In &, the cam projection 23 of the cam 16 of the material part and the cam protrusion 23 of the inner rotor 17 are in a locked state, so the inner ^ will rotate with the outer cam 16 as a whole, that is, the stator unit 12 and the rotor element 1 3 Relative rotation. As a result, the communication unit 2 and the answering unit 3 are automatically opened early. Also, the maximum opening angle is set within the mechanical rotation range of the hinge 4. Due to the resistance to the torsion coil spring 32 when the talking part 2 and the answering part 3 are closed, the axial force acting to the left is always applied to the inner rotor 17 by the compression coil spring 3, so the clutch unit 26 will be outside the clutch. The position where 27 is integrated with the inside of the clutch 28 again forms a connection state. Thereby, the rotational force of the torsion coil spring 32 is locked, so that the talking part 2 and the answering part 3 can be kept in a folded state. The above is only an example of using in a mobile phone, but the present invention can also be applied to, for example, a laptop computer.

Description of the invention (6) A hinge device that connects a keyboard portion and a display portion; or a hinge device that connects a cover body such as a storage device to the body. In the above description, the closed state is the normal state. However, depending on the position setting of the clutch unit and the direction of the action of the torsional force, the open state can be set to the normal state 'and closed automatically. In addition, in order to avoid the sudden release of the rotational force of the universal coil 32 by the torsion coil, a conventional rotary damper, such as a viscous fluid sealed, is preferably installed in an appropriate portion of the hinge 4. [Effects of the Invention] As described above, according to the present invention, when the call unit and the answering unit are slightly opened and folded into two folds according to the present invention, they will be automatically coaxed, and when closed, they can be used in the same manner as in the past. Turning it off can significantly increase the convenience of this folding machine. In addition, the actuator can be unitized to obtain a single-acting actuator capable of applying a rotational force to the hinge. Therefore, even if the specifications of the body are changed, the actuator itself can still be used, and great effects can be obtained in simplifying the manufacturing steps and component management.
