Abstract
본 발명은 드럼 모터(10)의 회전을 제어하는 드럼 서보계와, 캡스탄 모터(16)의 회전을 제어하는 캡스탄 서보계의 고장 유무를 판별하도록 하는 VCR 서보계의 고장 상태 알림 장치에 관한 것으로, 드럼 모터(10)의 회전시 기 설정 개수의 FG 펄스를 발생하는 FG 펄스 발생부(11); 상기 FG 펄스 발생부(11)에 의해 발생된 FG 펄스수를 카운트하는 FG 펄스 카운터(23); CTL펄스가 기록된 비디오 테이프(13); 상기 캡스탄 모터(16)가 회전함에 따라 상기 비디오 테이프(13)에 기록된 CTL펄스를 검출하는 제어 헤드(14); 상기 제어 헤드(14)에 의해 검출된 CTL펄스수를 카운트하는 CTL펄스 카운터(25); 상기 드럼 모터(10)와 캡스탄 모터(16)를 구동시킨후 기 설정 시간내에 상기 FG펄스 카운터(23)로부터 일정 카운트값이 제공되지 않으면 상기 드럼 서보계가 고장이라고 판별하고, 상기 CTL펄스 카운터(25)로 부터 일정 카운트값이 제공되지 않으면 상기 캡스탄 서보계가 고장이라고 판별하는 제어부(22); 제어부(22)의 제어에 의해 상기 드럼 서보계나 캡스탄 서보계가 고장이면 이를 나타내는 신호를 표시해주는 표시부(24)를 구비하여 구성함을 특징으로 한다.The present invention relates to a drum servo system for controlling rotation of a drum motor (10), and a failure state notification device for a VCR servo system for determining whether a capstan servo system for controlling rotation of a capstan motor (16) An FG pulse generating unit 11 for generating a predetermined number of FG pulses upon rotation of the drum motor 10; An FG pulse counter 23 for counting the number of FG pulses generated by the FG pulse generator 11; A video tape 13 on which CTL pulses are recorded; A control head (14) for detecting a CTL pulse recorded on the video tape (13) as the capstan motor (16) rotates; A CTL pulse counter (25) for counting the number of CTL pulses detected by the control head (14); If the predetermined count value is not provided from the FG pulse counter 23 within a predetermined time after driving the drum motor 10 and the capstan motor 16, the drum servo system is determined to be out of order and the CTL pulse counter A controller (22) for judging that the capstan servo system is out of order if a predetermined count value is not provided from the controller (25); And a display unit (24) for displaying a signal indicating the failure of the drum servo system or the capstan servo system under the control of the control unit (22).
