US 10,118,384 B2 · Liquid ejecting apparatus

Abstract

A liquid ejecting apparatus includes a drive circuit board on which a drive circuit which outputs a driving signal obtained by amplifying the original driving signal is mounted; an actuator substrate which includes an ejecting unit including a piezoelectric element which is driven by the driving signal, and ejects liquid when the piezoelectric element is driven; and a head unit a head unit on which a relay board which relays the driving signal to the piezoelectric element from the drive circuit board, the actuator substrate, the relay board, and the drive circuit board are mounted, and which is mounted on a carriage which reciprocates in an X direction as a main scanning direction. A mounting face of the drive circuit board is attached to the relay board so as to be placed in a direction which goes along the X direction in the main scanning direction of the carriage.
