Abstract

본 발명은 유선/무선방송 선택스위치 내장튜너에 관한 것으로, 종래 전자식 유선/무선방송 절환스위치가 구성된 튜너는 전자식 유선/무선방송 절환스위치, 제어신호선, 연결케이블등이 필요해 부품비 및 작업공수가 증가하고 연결케이블에서 신호강도가 약해지는 문제점이 있고, 종래 기구식 유선/무선방송 절환스위치가 투너의 안테나 입력단까지 2 내지 3데시벨 정도 신호 강도가 약해지고 사용자가 수동으로 발송절환 스위치를 조작하므로 사용상 불편함이 따르는 문제점이 있다. 본 발명은 이와같은 종래회로의 문제점을 감안하여 전자식 또는 기구식 유선/무선방송 절환스위치를 튜너와 일체화시켜 연결케이블은 인쇄회로기판상에서 패턴으로 신호선을 처리한 유선/무선방송 선택스위치 내장튜너를 창안한 것이다.The present invention relates to a built-in tuner for wired / wireless broadcasting selection switch, and the tuner configured with a conventional electronic wired / wireless broadcasting switching switch requires an electronic wired / wireless broadcasting switching switch, a control signal line, a connection cable, etc. There is a problem that the signal strength is weak in the connecting cable, and the conventional mechanical wired / wireless broadcasting switching switch has a weak signal strength of about 2 to 3 decibels up to the antenna input of the tuner, and the user manually operates the sending switching switch, thereby causing inconvenience. There is a problem that follows. In view of the problems of the conventional circuit, the present invention integrates an electronic or mechanical wired / wireless broadcasting switching switch with a tuner, and thus, a connection cable has a built-in tuner with a wired / wireless broadcasting selection switch in which signal lines are processed in a pattern on a printed circuit board. It is.

Claims (1)

무선 안테나(21)로부터 단자(RA3)로 인가된 무선방송신호와 단자(CA3)에 인가된 유선방송신호를 마이크로 프로세서(24)에서 인가된 스위치 제어신호에 의해 스위치(RS3)를 단자(RA3)또는 단자(CA3)사이로 절환시켜 선택하는 유선/무선방송 선택스위치(22)와, 이 유선/무선방송 선택스위치(22)에서 선택된 방송신호를 입력받고 튜닝을 하는 튜너(26)가 일체로 형성된 것을 특징으로 하는 유선/무선방송 선택스위치 내장튜너.The switch RS3 is connected to the terminal RA3 by a wireless broadcast signal applied from the wireless antenna 21 to the terminal RA3 and a wired broadcast signal applied to the terminal CA3 by a switch control signal applied by the microprocessor 24. Alternatively, the wired / wireless broadcast selection switch 22 for switching between terminals CA3 and the tuner 26 for receiving and tuning the broadcast signal selected by the wired / wireless broadcast selection switch 22 are integrally formed. Built-in tuner with wired / wireless broadcast selector switch. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
