<p>PURPOSE:To reduce the maximum load torque of a loading motor by providing an intermediate restraining means which is provided in the intermediate position between the start and the end of tape loading and restrains a following-up moving tape leading-out means and an end restraining means which is provided at the terminating position to restrain a main moving tape leading-out means. CONSTITUTION:When the first loading unit 6 reaches the first catching unit 12, the side face of an engaging pin 8 is abutted on a guide face 13a of a cam 13, and the first loading unit 6 is opened outward with a shaft 6a as the center. A top of the motor torque is formed by the first catching, and hereafter, only the second loading unit 3 is moved together with a driving loading ring 4 to wind up a tape and reaches the second catching unit 18 in the end of loading. According as the second loading unit 3 advances to push a retaining pin 22 open against the elastic force of a spring 24, it is pressed strongly to a drum base 23 and is caught. Thus, a maximum load torque of the loading motor is reduced, and a VTR is made small-sized and light-weight and the power consumption is reduced.</p> |
