Abstract

본 발명은 비디오테이프레코더의 헤드드럼상태 표시장치에 관한 것으로, 그 구성은 비디오테이프(20)의 기록 구간에 대한 제어모드의 실행을 위한 키설정 및 헤드드럼의 경과된 소모시간을 확인하기 위한 키설정을 행하는 제어기능 설정수단(10)과, 상기 헤드드럼(18)의 기능수행에 따른 소모치의 산정제어를 위한 제어프로그램 데이타가 메모리된 제1메모리수단(12), 상기 설정되는 제어모드의 실행동작에 따라 소모되는 헤드드럼(18)에 대한 소모산정치가 메모리된 제2메모리수단(14), 상기 제어모드의 실행동작에 따라 구동되는 헤드드럼(18)에 대한 실행동작의 시간을 계시하기 위한 계시수단(16), 상기 드럼모터(32)의 헤드드럼(18)구동을 위한 회전에 대응하는 펄스신호를 생성하는 펄스생성수단(38,40), 상기 제어기능설정부(10)에 설정되는 제어모드에 따라 구동되는 헤드드럼(18)의 구동소모치에 대한 소모시간이 가변되어 산정되도록함과 더불어, 그 산정된 소모시간을 통해 판정되는 경고메세지가 화면표시되도록 제어하는 마이컴(52) 및, 상기 마이컴(52)의 제어에 따라 상기 설정되는 제어모드의 실행동작에 따른 헤드드럼의 소모시간 경과에 대한 경고메세지를 화면 표시하기 위한 표시정보를 생성하는 표시신호처리수단(54)을 포함하여 이루어진 것으로, 비디오테이프레코더에서 헤드드럼의 구동에 관련된 제어모드 기능의 실행에 따라 구동되는 헤드드럼의 소모시간이 저장되어 그 저장된 소모데이타에 따라 그에 대응하는 메세지가 표시되므로 비디오테이프레코더의 사용에 따른 헤드드럼 청소 및 교체시기를 미연에 파악할 수 있는 이점이 있다.The present invention relates to a head drum state display device for a video tape recorder, and more particularly, to a key drum type state display device in which a key for setting a control mode for a recording section of a video tape (20) A first memory means (12) in which control program data for calculation control of consumptions according to the performance of the function of the head drum (18) is memorized, a control means A second memory means (14) for memorizing the consumed estimated value for the head drum (18) consumed in accordance with the operation, a second memory means (14) for memorizing the time of the execution operation for the head drum (18) Pulse generation means (38, 40) for generating a pulse signal corresponding to rotation for driving the head drum (18) of the drum motor (32), setting means for setting the control function setting means Depending on the control mode A microcomputer 52 for controlling the consumption time of the driving head drum 18 to be driven so as to be variable and controlling the display of a warning message determined through the estimated consumption time, 52), and display signal processing means (54) for generating display information for displaying a warning message on the elapsed time of consumption of the head drum according to the set operation mode of the control mode, The consumption time of the head drum driven according to the execution of the control mode function related to the driving of the head drum in the tape recorder is stored and the corresponding message is displayed according to the stored consumption data, There is an advantage in that the timing of replacement can be grasped beforehand.
