<p>PURPOSE:To make repeated supervisory video recording of a tape without troubling a supervisor by providing a switch that prohibits the action of automatic repeated video recording that operates after alarm video recording. CONSTITUTION:When an abnormal situation takes place and an alarm inputting terminal is made to L, the speed of a capstan motor is made a quick mode by a controlling circuit 9 and made to alarm video recording that makes scrupulous video recording. At the same time, L is outputted from an alarm memory circuit (6-a) and the input of (6-b) gate becomes L and the output becomes H. Accordingly, the input of the gate of (6-c) becomes H, and 'automatic rewinding' and 'automatic repeated video recording' are selected by a repeat switch 1, and even if L is inputted to this gate, the output becomes H. That is, the same thing takes placed as 'stop' is selected by 1. Thus, it can be stopped at the end of the tape only when the alarm input is made.</p> |
