Abstract

본 발명은 프론트로딩방식의 비디오테이프레코더에 관한 것으로, 특히 외부에서 데크이 하우징내부로 이물질이 삽입시 이를 감지하여 기기의 작동을 제어함으로써 기기 및 삽입물을 보호할 수 있는 삽입부 안전장치를 구비한 프론트로딩방식의 VTR에 관한 것이다. 본 장치는 발광소자와 수광소자로 구성된 광검출수단을 데크에 착설하여 데크내부에 이물질이 있는지를 검출한 후, 검출된 데이터에 따라 구동장치를 마이콤이 제어함으로써 삽입물이 데크내부에 존재할 경우 작동이 실행되지 않도록 한다. 이와 같이 본 장치는 실행에 앞서 삽입물의 존재여부를 점검함으로써 기기 및 삽입물을 보호할 수 있는 기능을 갖는다.The present invention relates to a front-loading video tape recorder, and in particular, a front having an insert safety device that can protect the device and the insert by controlling the operation of the device by detecting a foreign material when the deck is inserted into the housing from the outside. It relates to a loading type VTR. The device is equipped with a light detecting device consisting of a light emitting element and a light receiving element on the deck to detect whether there is foreign matter in the deck, and then the microcontroller controls the driving device according to the detected data to operate when the insert is present inside the deck. Do not run. As such, the device has a function to protect the device and the insert by checking for the presence of the insert prior to implementation.
