Liquid jetting apparatus, actuator device, and method for producing liquid jetting apparatus

摘要

A liquid jetting apparatus includes: a channel unit formed with a plurality of nozzles and a plurality of liquid channels communicating with the nozzles; an actuator including a plurality of drive sections, which are provided to correspond to the nozzles, include a plurality of connecting terminals, and are configured to apply jetting energy to a liquid in the liquid channels; and a flexible wiring member including a plurality of connecting portions joined to the plurality of connecting terminals of the actuator and a plurality of wires connected to the connecting portions. The wiring member includes a protrusion formed by bending a portion, different from a portion formed with the connecting portions, at which at least a part of the wires are formed, to project toward a side opposite to a connecting surface for connecting with the actuator.

1. A liquid jetting apparatus, comprising:
a channel unit formed with a plurality of nozzles and a plurality of liquid channels communicating with the nozzles;an actuator including:
a plurality of drive sections, which are provided to correspond to the nozzles respectively, include a plurality of connecting terminals, and are configured to apply jetting energy to a liquid in the liquid channels; and a flexible wiring member including: a plurality of connecting portions joined to the plurality of connecting terminals of the actuator respectively; and a plurality of wires connected to the connecting portions respectively; wherein the flexible wiring member includes a protrusion formed by bending a portion of the flexible wiring member, at which at least a part of the plurality of wires is formed and which is different from a portion formed with the connecting portions, in a mountain shape to project in a direction, which intersects and is away from a connecting surface, of the flexible wiring member, for connecting with the actuator; wherein the nozzles form a nozzle array extending in a predetermined first direction parallel to a first connecting surface, of the actuator, for connecting with the flexible wiring member; wherein the connecting terminals and the connection portions form a connecting terminal array and a connecting portion array respectively, each of which extends in the first direction to correspond to the nozzle array; and wherein the protrusion is formed as a plurality of protrusions by bending the flexible wiring member so that a concavity and a convexity are arranged in a second direction, which is parallel to the first connecting surface of the actuator and which is perpendicular to the first direction.
