装置。 In a printer head, an excitation voltage is applied to a piezoelectric actuator via a cored coil by inputting drive signals and braking signals from a microcomputer to a switching device at predetermined timing and turning the switching device on and off. When two or more drive signals are successively output from the microcomputer within the residual flow time, the second and subsequent drive signals rise earlier than the drive signals output outside the residual flow time. 1. A printer head driving device, comprising: means for inputting an image to said switching device.
