Abstract

본 발명은 방송 수신기의 모드를 신속 정확하게 선택 할 수 있는 방송 수신기의 키 확장 장치에 관한 것으로, 종래의 기술에 있어서는 자동차를 운전중인 운전자가 각 모드중 하나를 선택 하고자 할 때 모드 선택을 위한 스위치를 누르다가 원하는 모드가 나타날 때 그 모드에 따른 레벨을 조정 해야 하므로써 운전자 부주의에 의한 사고의 가능성이 많았으나, 본 발명에서는 스위치 조작부(1)에 다수의 프리셋을 형성하여 프리셋을 선택 할 때 마다 신속 정확하게 원하는 모드를 선택 할 수 있으며 라디오 수신기의 스위치 수를 줄이므로써 라디오 수신기의 크기를 작게 하므로 상기 결점을 개선 시킬 수 있는 것이다.The present invention relates to a key expansion device of a broadcast receiver capable of quickly and accurately selecting a mode of a broadcast receiver. In the related art, a driver for driving a vehicle selects a mode selection mode when a driver wants to select one of the modes. When the desired mode appears while pressing, there is a lot of possibility of accidents due to the driver's carelessness by adjusting the level according to the mode. However, in the present invention, a plurality of presets are formed on the switch control unit 1 so that each time a preset is selected, it is quickly and accurately. It is possible to select the desired mode and to reduce the size of the radio receiver by reducing the number of switches of the radio receiver can be improved the above drawbacks.
