Abstract

본 발명은 리모콘 신호를 송신하여 세트 동작을 제어하는 리모콘 송신기에서, 리모콘 신호 송·수신시와 키 누름시 빛이나 소리로써 확인시켜 줄 수 있도록 하는 리모콘 신호 송수신 회로에 관한 것으로 리모콘 송신기의 위치 확인 및 키누름을 확인할 필요가 있게 된다. 따라서 본 발명은 키매트릭스(100)의 키입력을 마이콤(200)에서 인식하여 리모콘 신호 송신부(300)로 리모콘 신호를 출력시키는 리모콘 송신기에 있어서, 외부 리모콘 신호를 수신하는 리모콘 신호 수신부(400)와, 소리나 빛이 출력 상태를 선택하는 모드 선택 스위치(600)와, 키매트릭스(100)와 리모콘 신호 수신부(400)의 입력을 인식하여 모드 선택 스위치(600)의 선택에 따라 구동 신호를 출력시키는 마이콤(200)과, 마이콤(200)의 구동 신호를 받아 빛이나 소리 신호를 출력시키는 구동부(500)를 구비시켜 된 것이다.The present invention relates to a remote control signal transmitting and receiving circuit for transmitting and receiving a remote control signal to control the operation of the remote control, and when the remote control signal transmission and reception and when the key is pressed by light or sound. You will need to confirm the keypress. Accordingly, the present invention provides a remote controller transmitter for recognizing a key input of the key matrix 100 in the microcomputer 200 and outputting a remote controller signal to the remote controller signal transmitter 300, and a remote controller signal receiver 400 for receiving an external remote controller signal. Recognizing the input of the mode selection switch 600 and the key matrix 100 and the remote control signal receiver 400 to select the output state of the sound or light, and outputs a driving signal according to the selection of the mode selection switch 600. The microcomputer 200 and the driver 500 which receives the driving signal of the microcomputer 200 and outputs a light or sound signal are provided.
