Abstract

본 발명은 비데오 카세트 레코더에 관한 것으로서, 서비스 옵션 모드시에 로딩 모터를 구동시키고, 캠 스위치로부터 출력되는 데이터가 변동되는가를 판단하여 캠 스위치의 이상 상태를 판별하고, 이를 OSD로서 표시하여 주므로써 사용자가 캠 스위치의 이상 여부를 용이하게 알 수 있게 된다.The present invention relates to a video cassette recorder, and more particularly, to a video cassette recorder which drives a loading motor in a service option mode, judges whether data outputted from a cam switch fluctuates and discriminates an abnormal state of the cam switch and displays it as an OSD, It is possible to easily know whether or not the cam switch is abnormal.

Claims (1)

로딩 모터의 구동에 의한 캠 기어의 회전에 의하여 스위칭이 제어되는 캠 스위치의 스위칭 상태에 따라 비데오 카세트 레코더의 현재 모드를 판별하는 비데오 카세트 레코더의 구동 방법으로서, 현재 모드가 서비스 옵션 모드인가를 판단하는 단계(11)와; 서비스 옵션 모드인 경우에 상기 로딩 모터를 구동시켜 상기 캠 기어로 상기 캠 스위치의 스위칭을 변동시키는 단계(13)와; 상기 로딩 모터의 구동 후, 소정 시간내에 상기 캠 스위치로부터 비데오 카세트 레코더의 구동 모드가 변동됨을 알리는 신호가 검출되는가를 판단하는 단계(15, 17)와; 상기 구동 모드의 변동을 알리는 신호가 상기 소정 시간동안 계속 검출되지 않는 경우에는 상기 캠 스위치의 이상을 표시하는 단계(19)와; 소정 시간내에 상기 구동 모드의 변동을 알리는 신호가 검출되면, 상기 캠 스위치가 정상임을 알리는 단계(21)를 포함하는 비데오 카세트 레코더의 캠 스위치 상태 판별 방법.A method of driving a video cassette recorder for determining a current mode of a video cassette recorder according to a switching state of a cam switch whose switching is controlled by rotation of a cam gear by driving a loading motor, Step (11); A step (13) of driving the loading motor to change the switching of the cam switch to the cam gear in the service option mode; A step (15, 17) of judging whether a signal indicating that the driving mode of the video cassette recorder is changed from the cam switch is detected within a predetermined time after the driving of the loading motor; A step (19) of displaying an abnormality of the cam switch when a signal informing the variation of the driving mode is not continuously detected for the predetermined time; And a step (21) of informing that the cam switch is normal if a signal indicating a change of the drive mode is detected within a predetermined time. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
