Abstract

In a liquid discharging apparatus, a head control unit, which controls an operation of a head unit, includes a first conversion circuit that converts an image signal input from an outside into a first electric signal, a first photoelectric conversion circuit that converts the first electric signal into an optical signal, the head unit, which discharges a liquid, includes a second photoelectric conversion circuit that converts the optical signal into a second electric signal, a second conversion circuit that converts the second electric signal into a discharge control signal for controlling discharge of a liquid. The first conversion circuit performs a first conversion process of converting the image signal into the first electric signal without depending on a discharge information, and the second conversion circuit performs a second conversion process of converting the second electric signal into the discharge control signal by using the discharge information.
