Abstract

PURPOSE:To drive a rotary solenoid with the least energy by a method wherein driving torque is secured by applying high voltage in the beginning of driving of the solenoid, and a rotary angle is ensured by generating the irreducible minimum torque when the driving operation is finished. CONSTITUTION:A command signal B instructing to give ON state to a solenoid 1 is outputted from a CPU (central processing unit), and the signal B is turned to the output signal B' to be outputted by the timing of a pulse signal A on a flip-flop circuit 7. The output signal B' and the output signal C of a counter 6 are inputted to an AND circuit, and outputted as a solenoid driving signal D for the purpose of preventing the generation of noise. In this case, high power is required in order to operate the solenoid 1 for a short period of X after a solenoid driving signal D has been outputted from the AND circuit, and during that period, an On counter output C is outputted from the counter 6. As small torque is enough to maintain the solenoid 1 during the period Y subsequent to the period X, the output signal C corresponding to the set signal outputted to the counter 6 from the CPU 5, for example, which is frequency-divided to one third, can be outputted from the counter 6.
