Abstract
PURPOSE:To increase the accuracy of stop position of the magnetic tape drawing out means and to smooth the unloading of magnetic tape, by driving the magnetic tape unloading means of magnetic tape unit without being effected to the position of rotation stop of motor. CONSTITUTION:The revolution of the motor 70 of the magnetic tape unit is delivered to the cam 72 via the belt 66 and the gear 68. Further, when the rotary angle of the cam 72 reaches 360 deg.C, the guide posts 20, 24 and 28, 30 move to specific position, and the tape unloading end switch is OFF to interrupt the power supply to the motor 70. In this case, the stop position of the guide posts 20, 24 and 28, 30 is restricted at the stoppers 25, 29 independently of the amount of overrun of the motor 70. Since the Bestehorn curve is used for the lift curve of the cam 72, the speed and acceleration of the sector type gear 78 is zero at halt, allowing to unload the magnetic tape smoothly.
