Abstract
PURPOSE:To improve the space efficiency of a driving circuit by supplying an operating voltage in a given value to a pulse motor, for which an arrangement is such that one given reference voltage or detection voltage will be selected from among reference voltage group or detection voltage group. CONSTITUTION:An electric circuit EC is put in a given circuit operation according to a prearranged order under control of a controlling device CD using a microcomputer. An electric supply ESP supplies an operating power variant in voltage value to a load L at a prearranged time and term under control of the controlling device CD. In case, for example, the load L is a pulse motor, such control as will impress a high voltage at start-up and a low voltage after start-up is given by the controlling device CD. Actually, a detection voltage at the junction of resistances R1 and R2 and one of the two reference voltages according to a command of the controlling device CD are compared with each other, and a conduction of transistor Qc is controlled.
