Patent ID: 8628171

Claim:
A liquid jetting apparatus comprising: a liquid jetting head which has a liquid jetting surface in which a plurality of nozzles are aligned along a predetermined nozzle alignment direction; a head holder which holds the liquid jetting head and which is rotatable within a plane parallel to the liquid jetting surface; a rotation regulation member which contacts with two contact portions of the head holder within the plane to regulate rotation of the head holder within the plane; and an inclination adjustment mechanism of the head holder, which has a cam member being rotatable about a rotation shaft provided in the head holder and being capable of displacing a first contact portion of the head holder, which is one of the two contact portions relative to the liquid jetting head, in a direction including a directional component perpendicular to a direction linking the first contact portion with a second contact portion of the head holder, which is the other of the two contact portions, within the plane, and which adjusts inclination of the head holder regulated by the rotation regulation member by rotating the cam member to rotate the head holder about the second contact portion, wherein the inclination adjustment mechanism includes a lever member which is attached to the cam member at a plurality of angular positions in a rotation direction of the cam member and which is rotatable integrally with the cam member in an attached state, wherein the head holder includes a carriage which holds the liquid jetting head and reciprocates in a first direction parallel to the liquid jetting surface, and wherein the rotation regulation member is a guide member which extends in the first direction, which has a guide surface not parallel to the liquid jetting surface, and which guides the carriage along the guide surface.
