Abstract
A recording head where an actuator, a cavity portion and a flexible flat cable are placed one on another is provided in a head holder of a carriage. A drive IC chip is mounted on the flexible flat cable. A bottom plate portion of a first heat sink is in contact with the drive IC chip so as to be thermally conductable, and a side plate portion thereof is disposed in a standing condition. A base end of a second heat sink is in contact, so as to be thermally conductable, with a wiring pattern formed portion of the flexible flat cable between the drive IC chip and the actuator, and a heat dissipating portion of the second heat sink is extended below the bottom plate portion, and a part of the heat dissipating portion is exposed to the outside of the head holder.
Claims5
A recording device comprising:
- a recording head having a plurality of recording elements and an actuator that includes a plurality of drive portions selectively driving the recording elements;
- a flexible flat cable having a wiring pattern that has one end electrically connected to the drive portions of the actuator and its other end connected to a signal source and a power source;
- a drive IC chip that is mounted on the flexible flat cable in a condition of being connected to the wiring pattern, and selectively supplies a drive voltage signal to the drive portions of the actuator;
- a first heat sink that is in contact with the drive IC chip so as to be thermally conductable;
- a head holder containing the recording head, the flexible flat cable, the drive IC chip, and the first heat sink;
- and
- a second heat sink that is in contact with a wiring pattern formed portion of the flexible flat cable between the drive IC chip and the actuator so as to be thermally conductable.
