Abstract
A recording head of a printer and its driving circuit are electrically connected via a flexible printed circuit that is provided with electrodes in pitch corresponding to the nozzles of the recording head and a general purpose flexible printed circuit. Thus, the manufacturing cost is reduced. In addition, the connection of both flexible printed circuits is prevented from being dirtied, and the handling during manufacturing is facilitated.
Claims27
A printer for recording an image on a recording medium, comprising:
- an actuator having at least one recording element;
- a printed circuit board that drives the actuator, the printed circuit board having a connector;
- a first flexible printed circuit having electrodes at one end and at another end, the electrodes at the one end having a pitch corresponding to the connector of the printed circuit board;
- a second flexible printed circuit having electrodes at one end and at another end, the electrodes at the one end having a pitch corresponding to the at least one recording element of the actuator, the electrodes at the other end having a pitch approximately equal to a pitch of the electrodes at the other end of the first flexible printed circuit;
- and
- a connection that connects the electrodes at each of the other ends of the first flexible printed circuit and the second flexible printed circuit.
