ABSTRACT:
Drivers (12a,12b) drive respective DC brushless motors (8a,8b) having rotor position detecting Hall-effect devices. A CPU (18) detects the numbers of rotations of the respective motors (8a,8b) in response to the detection of the positions of the rotors by the Hall-effect devices, and causes the driving of the motors (8a,8b) by the drivers (12a,12b) to stop when the detected number of the rotations attains a preset value.
