BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a folding-type portable telephone capable of automatically opening and closing a folder, and more particularly, to a folder opening and closing apparatus of a portable telephone capable of miniaturizing a device by improving a structure for opening and closing a folder.

In general, a cellular phone (Cellular Phone / Personal Communication Services) is a terminal that receives a mobile communication service to enable the use within a certain radius within the service area by radioizing a part of the locally fixed subscriber line. Whereas the communication is used in a fixed place by a line number, the mobile phone can make a call anywhere in the place by a logical personal number regardless of the line.

Such a mobile phone has an explosive demand due to its ease of portability and ease of use, and is becoming smaller and more versatile to satisfy various needs of consumers.

In general, a mobile phone has a bar type in which the number (function) button is exposed to the outside according to its shape, a flip type having a cover shielding the number (function) button with a cover, and a main body. It is classified into a folder type that is folded in half, and according to the trend of miniaturization, the spread of folder type mobile phones is increasing.

1 is a perspective view showing a general folding type cellular phone according to the prior art.

The conventional mobile phone 100 is composed of a main body 110 and a folder 120, the main body 110 is usually provided with a number (function) button and a microphone, there are various components for handset inside Built-in, the battery pack (B) for supplying power to one side is made.

The folder 120 includes a display window for displaying various call information and function information, a speaker, and the like, as well as various components.

In such a folding portable telephone, one end of the folder 120 is supported by the hinge means with respect to the main body 110, and the folder 120 is opened and closed by rotating in the forward or reverse direction about the hinge means.

However, in the conventional mobile phone 100 as described above, since the weight of the folder 120 is relatively heavy, in order to open and close the folder 120, the folder 120 must be opened with the other hand while holding the main body 110 with one hand. There was an inconvenience.

In order to improve such a problem, a mobile phone 100 has been recently proposed to open and close a folder 120 more easily. The representative method is to use a driving means.

On the other hand, when the folder 120 is rotated in one direction or the reverse direction from the main body 110 to manually open or close the folder 120, since the action force applied to the folder 120 is greater than the bearing force of the elastic spring 112, A slip is generated between the coupler 113 and the female coupler 114, and the male coupler 113 and the driving motor 116 are integrally compressed with the elastic spring 112 to cause a positional displacement. A meeting is made.

When the folder 120 reaches a predetermined position, the male coupler 113 is returned to its original position by the elastic support force of the elastic spring 112, and the folder 120 is rapidly opened by being recombined with the female coupler 114. It is closed.

However, in the folder opening and closing apparatus of the conventional mobile phone as described above, since the driving motor generates a driving force for a predetermined time by a timer, the output characteristic of the driving motor by long-term use, that is, revolutions per minute (RPM) is increased. If there is a change, there is a problem that the operating state does not reach the set position (Open position / Close position) that makes the full opening and closing of the folder 120.

The present invention was created in order to solve the above problems, an object of the present invention is to provide a drive control means that is selectively energized by contacting the folder and the main body so that the driving force of the drive motor in the opening and closing position of the folder is intermittent. It is an object of the present invention to provide a folder opening and closing device of a mobile phone to achieve a stable opening and closing of the.
