Patent ID: 8147031

Claim:
A recording apparatus comprising: a plurality of recording heads each of which includes an ejection surface to which a plurality of nozzles open; a head frame which has a plurality of through holes at arrangement positions where the plurality of recording heads are arranged and which supports the plurality of recording heads in a state in which the respective ejection surfaces of the recording heads are exposed through the respective through holes; at least one annular protrusion which encloses at least one of the ejection surfaces of the plurality of recording heads that is exposed through the head frame in a state in which the at least one annular protrusion is held in contact with the head frame; a support tray which supports the at least one annular protrusion and cooperates with the at least one annular protrusion to cover the at least one of the plurality of ejection surfaces; and a moving device which moves at least one of the head frame and the support tray such that the head frame and the annular protrusion are selectively positioned in either one of a spaced state in which the head frame and the annular protrusion are spaced from each other, and a contact state in which the head frame and the annular protrusion are held in contact with each other; wherein one or more positioning pins are provided in an inner area of the support tray that is enclosed with the annular protrusion, the positioning pins extending in a direction perpendicular to a flat surface which includes a contact portion of the annular protrusion that is come into contact with the head frame, and wherein the head frame has one or more positioning holes into which the positioning pins are insertable in the contact state of the annular protrusion.
