<p>PURPOSE:To reduce the size of tape recorder and the power consumption, by the constitution enabled to various operation conditions for control by using two voice coil type actuators and one circuit selector switch. CONSTITUTION:For example, power is applied so that the shaft 78 closes to the actuator 79 and the shaft 37 closes to the actuator 38, then the brake of the supply reel stand gear 9 is released, the over stroke lever 22 turns by taking the shaft 21 as the center. Thus, the pinch roller 14 is pressed to the capstan shaft 1 and the switch 44 is turned off. With this state, when the switch 146 is ON, the motor 4 turns with a constant speed and reproduction is made at the reproduction head 142. Further, at reproduction, when power is applied to the actuator 79 so that it is detached from the shaft 78, the reproduction operation is stopped. With this constitution, the unit can be made small in size and power consumption can be reduced.</p> |
