Patent ID: 8517520

Claim:
A liquid jetting apparatus which jets a liquid, comprising: a liquid jetting head which reciprocates in a first direction on a first plane and which jets the liquid from a nozzle; liquid supply sources which store the liquid to supply to the liquid jetting head; a plurality of flexible tubes, wherein: each of the flexible tubes constructs a part of a liquid flow passage from one of the liquid supply sources to the liquid jetting head; the flexible tubes are fixed to the liquid jetting apparatus at predetermined fixed portions which are different from connecting portions of the tubes at which the tubes are connected to the liquid jetting head respectively; the flexible tubes are arranged in a state that the tubes are bent and twisted at portions between the connecting portions and the fixed portions; and the flexible tubes have extending portions extending from the fixed portions to the portions at which the tubes are bent and twisted respectively; and a regulating member which is arranged at a position on an outer peripheral side of a bending direction of the tubes to regulate movement of the tubes in a second direction, on the first plane, perpendicular to the first direction, caused by bending of the tubes, and which has a facing surface facing the extending portions of the tubes and extending in the first direction; wherein the facing surface has a first end portion which is located in the vicinity of the fixed portions of the tubes and a second end portion which is opposite to the first end portion in the first direction; wherein the facing surface regulates the movement of the tubes in the second direction; wherein the tubes are arranged along a second plane which is intersecting with the first plane in the vicinity of the second end portion; and wherein the facing surface inclines in the vicinity of the second end portion with respect to a direction perpendicular to the first plane such that the facing surface is parallel to the second plane in the vicinity of the second end portion.
