Abstract

본 발명은 셀룰라폰에 관한 것으로, 특히 셀룰라폰을 고정장치에 부착한 상태에서 다이얼링 및 송수화가 가능하도록 된 셀룰라폰에 관한 것이다.The present invention relates to a cell phone, and more particularly, to a cell phone that is capable of dialing and handset while the cell phone is attached to a fixing device.

본 발명은 셀룰라폰을 고정장치에 고정시킨 상태에서 통화를 실행할 수 있으므로, 셀룰라폰 사용상의 편리성을 증가시킬 수 있다.According to the present invention, since the call can be executed while the cellular phone is fixed to the fixing device, the convenience in using the cellular phone can be increased.
