发明名称 CONTROL SYSTEM FOR MAGNETIC RECORDER/REPRODUCER
摘要 <p>PURPOSE:To check starting/ending time of a recording part of a tape by a simple operation by automatically feeding to reproduce the tape at a high speed, detecting presence or absence of a video signal, and calculating/recording the starting/ending time of a recorded part of the tape based on a tape remaining time at the time of variation. CONSTITUTION:A microcomputer 2 control the entirety, and sends, receives a command, information to or from a video/signal processing unit 3, a tape remainder calculating/system control unit 4, a character signal generation unit 5, etc. Presence/absence of a video signal on a tape is always detected at the times of fast forwarding/reproducing, a tape remaining time of each time is always calculated simultaneously, and when a varying point in the video signal is detected, the position of the varying point is calculated as time data from the starting end reference position of the tape at the time of recording (reproducing) speed by referring to the remaining time data of the time point, sequentially stored in a predetermined memory area, and displayed on a monitor 6. Thus, a user can simply, easily check recording/ unrecording of the tape at a high speed before the recording is started.</p>
