Patent ID: 7533955

Claim:
A recording apparatus, comprising: a recording head including an actuator and operable to perform recording by an operation of the actuator; a head holder holding the recording head; a circuit board disposed on the head holder and configured to be connected to an external signal source; a drive circuit operable to drive the actuator; a flexible wiring member which includes a plurality of conductor wires that connect the actuator and the circuit board, which is elongated in a direction in which the plurality of conductor wires extend, which is connected to the actuator and the circuit board at longitudinally opposite ends thereof, respectively, and on which the drive circuit is mounted between the longitudinal opposite ends, the plurality of conductor wires including a common voltage wire which connects a common-voltage portion of the drive circuit and a common-voltage portion of the circuit board and a drive signal wire for driving the actuator; and a radiator having heat conductivity and electric conductivity and disposed between the recording head and the circuit board so as to extend along the flexible wiring member, the radiator being heat-conductively and electrically joined to: (a) the common voltage wire in the vicinity of the drive circuit; (b) at least one portion of the common voltage wire intermediate between the drive circuit and the circuit board; and (c) at least one of (c- 1 ) the common voltage wire in the vicinity of the circuit board and (c- 2 ) the common-voltage portion of the circuit board which is connected to the common voltage wire of the flexible wiring member.
