Ink-jet recording apparatus
First Claim
1. An ink-jet recording apparatus which jets droplets of an ink onto a recording medium, comprising:
- an ink-jet head which selectively jets the droplets of the ink, including a cavity unit in which a cavity and a plurality of nozzles which communicate with the cavity are formed, and an actuator which applies a jetting pressure to the ink in the cavity;
a circuit board on which an electric circuit which is electrically connected to the actuator is formed, the circuit board being arranged on the ink-jet head on a side opposite to the nozzles;
an ink supplying unit which is arranged between the ink-jet head and the circuit board, the ink supplying unit including an ink storage section which stores the ink to be supplied to the ink-jet head, an exhaust section which is connected to the ink storage section to remove air bubbles generated in the ink stored in the ink storage section, and a space formed in the ink supplying unit penetrating therethrough from a side of the ink-jet head of the ink supplying member up to the circuit board, the space being formed between the ink storage section and the exhaust section; and
two flexible flat cables which connect the actuator and the circuit board, the flexible flat cables including a first flexible flat cable which is wired to pass along a side, of the ink storage section, opposite to the exhaust section, and a second flexible flat cable which is drawn from the actuator to the other side, of the ink storage section, opposite to the first flexible flat cable to be wired to pass through the space.

Abstract
An ink-jet recording apparatus includes an ink supplying member which has an ink storage section, an exhaust section, and a space portion formed between the ink storage section and the exhaust section, an ink-jet head, and two flexible flat cables (FPC) which are drawn in mutually opposite directions from the ink-jet head. One FPC is wired by passing along a side of the ink supplying member, opposite to the exhaust section, and the other FPC is wired by passing through the space portion. Since the FPC is wired avoiding the ink supplying member and the exhaust section, it is possible to eliminate adhering of ink to the FPC, and to eliminate a waste of FPC wiring. Moreover, it is possible to reduce a cost, and to uniformize electrical characteristics of the two flexible flat cables.
