PURPOSE:To reject the shift in timing of stop/start caused by various resistances such as brush resistance in a motor itself, by inserting a feedback loop including diodes to a current booster circuit. CONSTITUTION:In a feedback loop including diodes D51, D52 in a motor driving circuit 54, the cutoff voltage of diodes D51, D52 is designed so that it is the same valve as the voltage of start/stop of a motor 31. Thus, in the region of start/stop of the motor 31, the shift in driving the motor 31 can almost be zeroed. |
