Claims (1)

영상녹화재생기의 기록기능 체킹방식에 있어서, 한입력이 각각 접지된 아프터 체킹레코딩키(1)와 리세트키(2)의 양단에 바이어스저항(R3-R4)이 각각 접속되며, 상기 저항(R3-R4)의 양단에 직렬 접속되어 아프터 체킹레코드키(1)가 압압시 카운터 리세트신호가 발생하는 다이오드(5)로 구성된 신호발생부(10)와, 전원전압의 공급에 의하여 발광되는 발광다이오드(6)와 바이어스 저항(5)와 포토트랜지스터(8)로 구성되어 테이프의 리더영역 (Leoder Area)을 검출하는 릴셀서부(20)와 소정프로그램에 의해 상기 신호발생부(10)과 릴센서부(20)에서 출력하는 신호로서 시스템 동작신호를 출력하는 마이컴(30)과 상기 마이컴(30)에서 출력하는 시스템 동작신호에 의해 텍크(Deck)를 구동하여 입력되는 정보를 녹화하거나 재생하는 텍크부(40)와. 상기 덱크부(40)에서 출력하는 재생신호의 포락선(Envelope)을 검출하는 포락선검출부(50)와, 상기 마이컴(60)에서 출력하는 데이터에 의해 이상상태를 표시하는 표시부(60)를 구비하여, 상기 신호발생부(10)에서 아프터 체킹레코딩 신호가 발생되었는가를 검색하여 발생시에는 레코딩모드의.데이터를 덱크부(40)로 출력하여 레코딩 동작을 실행하고, 상기의 레코딩 시간이 소정의 시간이 되었는가를 검색소정 시간에 이르렀을때 마이컴(30)이 스톱모드의 데이타와 리와인드의 모드신호를 연속적으로 텍크부(40)로 출력하여 리와인드가 끝났는가를 검색하며, 상기 릴센서부(20)에서 리터테이프영역을 검출시 리와인드가 끝났다고 판단하고 재생모드의 데이터를 텍크부(40)로 출력하여 기록된 신호를 재생하며. 상기 재생신호의 포락선을 포락선검출부(50)를 통해 검출 입력하여 포락선 상태가 양호한 레베일때 레코딩모드의 데이터를 덱크부(40)로 출력하여 계속적으로 레코딩모드를 수행하며, 양호치 못할시 스톱모드의 데이터를 덱크부(40)로 출력하여 현재의 동작을 중지시킴과 동시에 표시부(60)로.데이터를 출력하여 이상기록을 디스플레이함을 특징으로 하는 영상녹화재생기의 기록기능 체킹방식.In the recording function checking method of a video recording / reproducing player, bias resistors R 3 -R 4 are connected to both ends of an after checking recording key 1 and a reset key 2 each having one input grounded. A signal generator 10 comprising a diode 5 connected in series to both ends of R 3 -R 4 and generating a counter reset signal when the after checking record key 1 is pressed, and supplying a power supply voltage The signal generator 10 includes a light emitting diode 6, a bias resistor 5, a phototransistor 8, and a reel cell 20 for detecting a leader area of a tape and a predetermined program. And recording or reproducing information input by driving a deck by a microcomputer 30 that outputs a system operation signal as a signal output from the reel sensor unit 20 and a system operation signal that is output from the microcomputer 30. With the technical part 40 to do. An envelope detection unit 50 for detecting an envelope of a reproduction signal output from the deck unit 40, and a display unit 60 for displaying an abnormal state by data output from the microcomputer 60; The signal generator 10 detects whether an after checking recording signal is generated and outputs the data in the recording mode to the deck unit 40 to execute a recording operation when the signal is generated. The recording time has been a predetermined time. When the search predetermined time is reached, the microcomputer 30 continuously outputs the stop mode data and the rewind mode signal to the tac unit 40 to search whether the rewind is finished, and the reel sensor unit 20 relieves the tape. Upon detection of the area, it is determined that the rewind has been completed, and data of the reproduction mode is output to the text unit 40 to reproduce the recorded signal. When the envelope of the reproduction signal is detected and input through the envelope detector 50, when the envelope is in a good level, the recording mode is output to the deck unit 40 to continuously perform the recording mode. Outputting data to the deck unit 40 to stop the current operation, and at the same time to the display unit 60. a recording function checking method of the video recording and reproducing, characterized in that to display the abnormal recording. ※ 참고사항 : 최초출원내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
