Abstract
An engaging groove part 25 is provided at the outer circumferential edge of a rotor 20b of an outer-rotor type motor directly connected to the main shaft 14 of a drum 13, and on the other hand, a drum locking device 21 is provided directly below the shaft. The drum locking device 21 is constructed so that a lock pin moves up and down in response to rotation of a torque motor, and when the lock pin advances and fits into the groove of the engaging groove pan 25, the position of the drum 13 is fixed. Thereby, the stopping position of the drum can be fixed with a simple construction.
