Abstract:
1. A driving apparatus comprising: (a) a drive source outputting a drive force; (b) a drive force interruption/transmission device for transmitting or interrupting the drive force from the drive source; (c) a load unit operating by the drive force transmitted from the drive force interruption/transmission device; (d) a torque control unit for varying the output torque of the drive source; (e) a drive force interruption control unit for controlling the operation of the drive force interruption/transmission device; and (f) a drive timing control unit for controlling the torque control unit and the drive force interruption/transmission control unit; wherein said torque control unit comprises a drive circuit for controlling the current of the drive source, and after the drive circuit has increased the current of the drive source from a first current value for causing the drive source to generate a first output torque, to a second current value for causing the drive source to generate a second output torque higher than the first output torque, the drive force interruption/transmission device transmits the drive force from the drive source to the load unit.
