Abstract:
1. An apparatus comprising: a conveying mechanism configured to convey a sheet in a first direction; a line recording head in which nozzles are arrayed along a second direction intersecting the first direction; a holder configured to hold the line recording head, the holder having a first abutment portion in the first direction, a second abutment portion in the second direction, and a third abutment portion in a third direction that is a direction of a gap between the nozzles and the sheet direction; a displacement mechanism configured to displace the holder in the second direction and the third direction, the displacement mechanism having a fixed portion and a movable portion; an elastic portion provided between the movable portion and the holder and configured to exert an urging force in the second direction; and a reference portion having a first positioning surface that can come into contact with the first abutment portion, a plurality of second positioning surfaces that differ in the second direction and that can come into contact with the abutment portion, and a third positioning surface that can come into contact with the third abutment portion, wherein when the line recording head is to be positioned in the second direction, the holder is displaced in the second direction against the urging force of the elastic portion using the displacement mechanism to bring the abutment portion into contact with one of the second positioning surfaces, thereby positioning and fixing the holder to the reference portion, with the urging force exerted thereto.
