<p>PURPOSE:To improve operability and quick response with an inexpensive device by providing the presence or absence flag of a main signal and changing the time of an action mode to move next by the sequence control of the reproducing device of a recording medium where a voice signal, etc., is recorded. CONSTITUTION:A system controller 26 detects the presence or absence of the main signal by the signal of an error correcting circuit 20 and when it is present, the flag is set into 1. When it is absent, the main signal flag is decided, when it is set, when the main signal is absent for 3sec, the controller 26 drives reel motors 33 and 34 by a reel driving circuit 32 and a quick traverse mode is attained. At the time of the reset of 0, the quick traverse mode is attained in the same way as the case that the main signal is absent for 1min. That is to say, by the present or absence of the preceding main signal, the time of the action mode to move next is changed, when the main signal is present, an action with good quick response is attained and when the main signal of a cleaning tape, etc., is absent, a sufficient reproducing time is obtained.</p> |
