Abstract

본 발명은 테이프의 잔량값에 따라 앤드 센서의 전원을 온/오프함으로써 소비전력을 절약하고 테이프의 손상으로 인한 오동작을 방지할 수 있는 VCR의 앤드 센싱 제어장치 및 방법에 관한 것이다.The present invention relates to an end-sensing control apparatus and method of a VCR capable of saving power consumption and preventing malfunction due to tape damage by turning on / off the power of the end sensor according to the remaining value of the tape.

이와같은 본 발명의 VCR의 앤드 센싱 제어장치 및 제어방법은 각 부에 전원을 공급하는 전원 공급부와, 상기 전원 공급부로부터 동작 전원을 인가받아 테이프의 시작과 끝을 검출하기위한 앤드 센서와, 테이프의 잔량값을 산출하여 출력하는 테이프잔량 산출부와, 상기 테이프 잔량 산출부의 출력값을 판단하여 테이프의 시작영역과 끝영역에서만 상기 전원 공급부에서 앤드 센서로 전원이 공급되도록 제어하는 전원 제어부를 포함하여 구성되고, 테이프의 시작영역과 끝영역을 설정하여 설정된 영역에서만 앤드 센서가 동작되도록 제어한 것이다.The end-sensing control device and control method of the VCR of the present invention includes a power supply for supplying power to each unit, an end sensor for detecting the start and end of the tape by receiving operating power from the power supply, And a power remaining control unit configured to calculate a remaining amount value and output the remaining amount value calculating unit, and a power control unit configured to determine an output value of the remaining amount calculating unit and to control power to be supplied from the power supply unit to the end sensor only in the start region and the end region of the tape. By setting the start and end areas of the tape, the end sensor operates only in the set area.
