摘要
In an electronic device 1 comprising a battery 200 and a piezoelectric actuator A, a power source voltage before drive control is started is maintained by a sample holding circuit 102, a reference voltage is set by a reference voltage generating circuit 103 on the basis of the power source voltage, and a control circuit 106 stops driving when the power source voltage falls below a drive stop voltage as compared by a second comparison circuit 105, and begins driving the piezoelectric actuator A again when the power source voltage exceeds the reference voltage as compared by a first comparison circuit 104. Therefore, the device can be more easily reduced in size by using a small power source, and the driving time can be markedly reduced using an intermittent driving procedure that corresponds to the conditions of the battery voltage.
