Abstract

본 발명은 비데오 카세트 레코더에 관한 것으로서, 서비스 옵션 모드의 설정시, VCR을 고속 전진 및 고속 후진 모드로 구동시켜 스타트 및 엔드 센서(S1, S2)로부터 스타트 및 엔드 신호가 소정 시간내에 인가되는 가를 판단하여 스타트 및 엔드 센서(S1, S2)정상 동작 여부를 OSD로서 표시하여 주므로 사용자가 스타트 및 엔드 센서(S1, S2)의 이상 여부를 용이하게 알 수 있다는 효과가 있다.The present invention relates to a video cassette recorder, and more particularly, to a video cassette recorder that drives a VCR in a high-speed forward and a fast reverse mode to set whether a start and end signal is applied within a predetermined time from a start and end sensors It is possible to easily recognize whether the start and end sensors S1 and S2 are abnormal or not, since the operation of the start and end sensors S1 and S2 is displayed as the OSD.

Claims

A method for determining whether a start and end sensor (11, 12) is abnormal in a video cassette recorder capable of detecting start and end portions of a tape as start and end sensors (11, 12) Determining whether the mode is a mode (11); Determining whether the mode is an end sensor determination mode in a service option mode (12); (13) driving the video cassette recorder to a fast forward mode if it is in the end sensor determination mode; A step (14,15) of determining whether a signal indicating that the end of the tape is sensed from the end sensor (S2) is applied within a predetermined time after driving in the fast forward mode; (17) indicating an abnormality of the end sensor (S2) when a signal indicating that the end of the tape has been detected from the end sensor (12) is not detected within a predetermined time; (S16) indicating that the end sensor (S2) is normal when a signal indicating that the end of the tape has been sensed from the end sensor (S2) is applied within a predetermined time; (18) driving the video cassette recorder to a fast reverse mode if the mode is not the end sensor determination mode; A step (19, 20) of judging whether a signal indicating that a start of a tape is sensed from the start sensor (S1) is applied within a predetermined time after driving in a fast reverse mode; (22) indicating an abnormality of the start sensor (S1) when a signal indicating that the start of the tape has been detected from the start sensor (S1) is not detected within a predetermined time; And a step (21) of informing that the start sensor (S1) is normal when a signal indicating that the start of the tape is detected from the start sensor (S1) is applied within a predetermined time is discriminated from the start and end sensor status of the video cassette recorder Way.
