<p>PURPOSE:To attain stable transmission mechanism and miniaturization by constituting the device to deliver by switching the torque of a loading motor to a loading mechanism and an operating cam for mechanism element control, and the operating cam is locked during loading operation. CONSTITUTION:When a tape cassette is loaded and a loading motor 3 is driven, the operating cam 61 is driven via a torque transmission mechanism and main brakes 13a, 13b and bus-brakes 14a, 14b are controlled. When the operating cam 61 is turned for a prescribed angle, the motor torque is fed from the operating cam 61 to the loading ring 23 to load the magnetic tape to the cylinder 2. When the loading is finished and the loading ring is stopped, the operating cam 61 is turned again. Thus, the moving of the pinch roller 10 to the capstan 9 and drive of each mechanism element are conducted and a prescribed mode is set. The torque transmission mechanism is made stable and miniaturized in such a way.</p> |
