ABSTRACT:
An image recording apparatus, including a carriage which is reciprocated in a reciprocating direction; a pair of guide frames which extend parallel to each other in the reciprocating direction and which cooperate with each other to guide a reciprocating movement of the carriage, wherein the two guide frames are separate from each other in a conveying direction in which a recording medium is conveyed and which is perpendicular to the reciprocating direction, and wherein the carriage includes a main frame which is supported by the two guide frames such that the main frame bridges the two guide frames, and additionally includes at least two sliding members each of which has a sliding surface which slides on a corresponding one of the two guide frames in the reciprocating direction; an image recording head which is mounted on the main frame of the carriage and which records an image on the recording medium; a driving device which reciprocates the carriage in the reciprocating direction; and a gap adjusting device which changes, by utilizing a portion of the reciprocating movement of the carriage, a distance between the sliding surface of said each of said at least two sliding members and the main frame in a perpendicular direction perpendicular to the reciprocating direction and the conveying direction and thereby adjusts, in the perpendicular direction, a gap between the recording medium and the image recording head mounted on the main frame.
