Abstract:
1. A recording apparatus comprising: a head that discharges ink; a head driving circuit that drives the head; a switching signal generating unit that generates and outputs a switching signal; a first switch that is turned on or off based on the switching signal; a second switch that is turned on or off based on the switching signal, wherein a first DC voltage is converted into a second DC voltage by turning on one of the first switch and the second switch based on the switching signal, and the turned on one of the first switch and the second switch supplying the second DC voltage to the head driving circuit; a temperature detector that detects a temperature of the head or a temperature of the ink in the head; and a controller that controls the switching signal generating unit to generate the switching signal, wherein the controller controls the switching signal generating unit to output the switching signal to the first switch when the detected temperature is less than a first predetermined temperature and to output the switching signal to the second switch when the detected temperature is equal to or greater than the first predetermined temperature, wherein the first switch and the switching signal generating unit are realized on a single integrated circuit chip, and the second switch is attached external to the integrated circuit chip having the first switch thereon.
