<p>PURPOSE:To lower power consumption by providing a logical operation circuit that processes logically signals from an operation command switching means that inputs operation command, and controls to operate two cassette mechanisms delaying with time. CONSTITUTION:When dubbing command is inputted from a dubbing switching means 6 as an operation commanding switch, a cassette mechanism for recording and reproducing 2 starts driving, and after the lapse of a time T, a cassette mechanism exclusively used for reproducing 1 starts driving. By this operation, overlapping of transient states in which power consumption of the two cassette mechanisms 1, 2 becomes maximum can be prevented and power consumption can be reduced. That is, by inputting operation command such as reproducing, stopping, quick feeding etc. by an operation command electric switching means 4, a logical operation circuit 3 controls the mechanism 1 to make the mechanism 1 realize respective mode of reproducing, stopping, quick feeding etc., and controlled by an operation command electric switching means to make the mechanism 2 realize respective modes.</p> |
