Patent ID: 8336992

Claim:
A liquid discharge apparatus which discharges liquids, comprising: a liquid discharge head which reciprocates in a first direction on a predetermined plane, which discharges the liquids from nozzles and which has a plurality of connecting ports arranged in a second direction on the predetermined plane; liquid supply sources which store the liquids to be supplied to the liquid discharge head; a plurality of flexible tubes which are arranged in a state of being bent and each of which constructs a part of a liquid flow passage from one of the liquid supply sources to the liquid discharge head; and a flexible wiring member which applies a driving electric potential to the liquid discharge head; wherein first ends of the tubes are connected to the connecting ports respectively; wherein the tubes are fixed to the liquid discharge apparatus at fixed portions of the tubes in a state that the tubes are arranged in a third direction intersecting the predetermined plane, the fixed portions being located at positions different from positions of the connecting ports of the liquid discharge head in relation to a direction which is perpendicular to the first direction and parallel to the predetermined plane; and wherein each of the tubes has a cross section which is perpendicular to an extending direction of the tube and which has an elliptical external shape; wherein, in at least at one of the first end and the fixed portion, a major axis direction of the elliptical external shape is the third direction; and wherein the flexible wiring member has a width in the third direction and which is smaller than sum of lengths of major axes of the tubes arranged in the third direction at the fixed portions.
