Abstract
A capacitive load drive circuit, which may be embodied in a printer, includes capacitive elements; a first circuit substrate, on which is installed a control signal supply unit that generates control signals; a second circuit substrate, on which is installed a circuit that charges or discharges the capacitive elements according to the control signals; and a flexible flat cable, on which is formed wirings including control wiring, which transmits the control signals from the first to the second circuit substrate, and a wiring, which supplies power supply and ground voltages to the second circuit substrate. A total path length of the wirings between the first and second circuit substrates is shorter than the total path length of the wiring between the second circuit substrate and each of the capacitive elements.
