Abstract

본 발명은 차량에 부착되는 카오디오에 관한 것으로서, 더욱 구체적으로는 차량내부에서 무선호출신호를 수신할 수 있는 무선수선장치를 가진 카오디오에 관한 것이다. 본 발명의 무선호출기가 내장된 카오디오는, 공중을 전파하는 무선신호를 수신하는 안테나와 상기 안테나를 통하여 수신된 신호중에서 라디오주파수신호를 선택하기 위한 무선수신부와, 상기 무선수신부를 통하여 수신된 신호를 복조하기 위한 복조부와, 전체 행정을 제어하기 위한 제어부와, 상기 제어부에서 필요한 기능을 수행하도록 명령을 입력시키는 키입력부와, 상기 제어부로부터의 신호에 따라서 CD를 재생하는 CD재생부와, 상기 제어부로 부터의 신호에 따라서 테이프를 재생하는 테이프재생부와, 상기 제어부로부터의 출력 신호에 따라서 작동상태를 표시화기 위한 표시부와, 상기 CD또는 테이프 재생신호를 스피커를 구동시키도록 처리하는 출력부를 포함하는 카오디오에 있어서, 공중을 통하여 전송되는 무선신호를 수신하기 위한 제2안테나와, 제2 안테나로부터 입력되는 신호중에서 무선호출신호를 복조하기 위한 무선수신부와, 사용자의 식별번호에 해당하는 고유번호, 수신메시지등을 저장하기 위한 메모리부를 포함하며, 무선호출신호가 수신되면 진행중인 동작을 정지하고 운전자에게 호출신호를 출력한다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a car audio to be attached to a vehicle, and more particularly to a car audio having a radio repair device capable of receiving a radio paging signal in a vehicle. The car audio having the radio pager of the present invention includes a radio receiver for selecting a radio frequency signal from an antenna for receiving a radio signal propagating through the air and a signal received through the antenna, A key input unit for inputting a command to perform a necessary function in the control unit; a CD playback unit for playing back the CD according to a signal from the control unit; A tape reproducing section for reproducing the tape in accordance with a signal from the control section, a display section for displaying the operating state in accordance with the output signal from the control section, and an output section for processing the CD or tape reproducing signal to drive the speaker And a second antenna for receiving radio signals transmitted through the air, A radio receiver for demodulating a radio paging signal among the signals input from the second antenna, and a memory for storing a unique number, a reception message, etc. corresponding to the identification number of the user, Stops the operation and outputs a call signal to the driver.
