Ink-jet recording apparatus

Abstract

To provide an ink jet recording apparatus wherein distorting the waveform of a drive signal can be prevented, a recording head also containing a drive signal generating circuit can be tested, and the detrimental effect when such a configuration is adopted can be avoided. In the ink jet recording apparatus, a heat radiation member 200 is placed in a recording head 100 and an IC 300 is mounted on a vertical plate section 210 of the heat radiation member 200. The IC 300 is provided with not only a head drive circuit, but also a current amplification circuit of a drive signal generating circuit for generating a drive signal to drive a pressure generating element 17. The recording head 10 is attached to a carriage in a state in which the vertical plate section 210 of the heat radiation member 200 is brought into contact with the carriage with heat radiation fins.
