CAMERA DOOR OPENING AND SHUTTING APPARATUS FOR FOLDER TYPE MOBILE PHONE}

The present invention relates to a camera door opening and closing device of a clamshell mobile phone, and more particularly, to a camera door opening and closing device of a clamshell mobile phone configured to automatically open and close a pair of camera doors using a driving motor in a camera phone of a clamshell mobile phone. It is about.

In general, the term “portable communication device” refers to a device that a user can carry and perform wireless communication with a counterpart. Such portable communication devices are referred to as HHP, CT-2 cellular phones, digital phones, PCS phones and PDAs, and are classified into various types in appearance. For example, wireless terminals are classified into bar-type, flip-type, or folder-type wireless terminals according to their appearance. The bar-type wireless terminal means that the single housing is configured as a bar-type, and the flip-type wireless terminal means that the flip or cover is rotatably configured by the hinge device in the bar-type housing. The terminal means that the folder is configured to be rotatably connected to the single bar-shaped housing by a hinge device and to be folded.

In addition, in the conventional portable communication device for a video call, the photographing means includes a camera lens, through which a video call with the other party or a desired subject can be taken.

In addition, most of portable communication devices mainly intended for voice communication or video communication have a large number of terminals such as flip type or folder type.

Such flip-type or clamshell terminals have excellent sound sensitivity, and are currently in a generalized trend because they are advantageous for miniaturization and light weight of the main body.
