<p>PURPOSE:To achieve small size and low cost without the deterioration of sound quality, by turning an unloaded cassette over automatically through the detection signal from a tape end detector. CONSTITUTION:A part of a signal through a tape end detector 77 or depression of a push button switch 76 is inputted to a monostable circuit 77a, the output is kept for a short time, and the output of an amplifying circuit 77a is obtained for the while. When a motor 1 is supplied for power and turned for a short time with this output, a gear 36 turns counterclockwise and a projection 36b is detached with a lever 39. In this case, since the power application to an energizing coil 38a is already interrupted, the lever 39 is in spring back. Thus, since the application of power to the motor 1 is interrupted after that, a supporting stand 43 moves right with a spring 47 for enabling the specified automatic reversing.</p> |
