<p>A power supply is provided that controls several actuators 15a, 15b, one of which 15b draws a higher current than the others 15a. From a single voltage-increasing circuit 10 a plurality of control lines 12a, 12b feed each actuator 15a, 15b through a plurality of driving circuits 14a, 14b. An auxiliary control line 12b' is additionally connected to the high current actuator 15b through a switch 11c, whilst a voltage-holding circuit 13 is connected to the other actuators 15a, to reduce the influence of actuation of the high current actuator 15b on the other actuators 15b.</p> |
