In the prior art as described above, the hook switch and the pressing portion are arranged in the vicinity of the rotating shafts of both housings, and the pressing portion provided on the other housing is It is formed integrally with the housing. A hook switch with a relatively large size like this conventional technology,
There is no particular problem when it is turned on / off in the vicinity of the rotating shaft, but due to the demand for further downsizing of the product, it may be necessary to provide it at a position apart from the rotating shaft as the hook switch itself becomes smaller. is there. In such a case, it is possible that the hook switch cannot be turned on / off reliably if the processing accuracy and assembly accuracy of both cases are not sufficient, and the line is not disconnected even if the call is ended and the opening / closing lid is closed. There was a problem that various failures could occur.

The present invention solves the above-mentioned problems, and even a small hook switch is
The present invention realizes a mobile phone device capable of performing reliable hook control regardless of the position of the hook switch.

[0006]

A mobile phone device according to the present invention is provided with a mobile phone main body provided with a hook switch, and an operation unit provided rotatably on the mobile phone main body and pressing the hook switch. In a mobile phone device configured to perform on-hook / off-hook control by opening and closing the opening / closing lid, the operating section is a fixed section, a movable section, and the movable section is a It is characterized in that it is composed of an elastic member that urges in the closing direction.

Further, the present invention is characterized in that the hook switch is built in the inside of the main body of the portable telephone and is operated by the operation section through an operation hole provided in the main body of the portable telephone.

[0008]

According to the present invention, the operation section presses the hook switch through the operation hole in conjunction with the closing operation of the opening / closing lid,
On-hook / off-hook control is performed. At this time, the movable portion of the operation portion slides toward the fixed portion against the biasing force of the elastic member, absorbs dimensional error and assembly error between the mobile phone body and the opening / closing lid, and reliable hook control is performed. .
