PURPOSE:To switch the control system of a solenoid and a stepping motor for difference source voltages. CONSTITUTION:The heat generation and insufficient driving force of the solenoid 3 can be solved and the slow-up and slow-down operation of the stepping motor 4 can also be stabilized by switching the electrification ratio and driving time of the solenoid 3 corresponding to an inputted source voltage and also by switching the driving cycle of the stepping motor 4. |
