<p>PURPOSE:To simplify the constitution of a turning and reversing circuit for a loading motor, by using a mechanical switching method as the electric switching method for the loading motor. CONSTITUTION:Between common terminals of switches 64 and 65, loading motor 29 is connected. In a stop state, the contacts of switches 64 and 65 are grounded and motor 29 is stationary, but the moment recording button 5 or reproducing button 7 is depressed, switch 64 turns ON and motor 29 starts turning in a loading direction. After the loading ends, switch 64 is at the earth side and the motor stops. Once a recording or reproducing state is released, switch 65 turns ON and motor 29 turns in an unloading direction until the unloading ends. In this way, the loading motor can be turned and reversed by the simple circuit constitution.</p> |
