An image recording apparatus including: (a) a head assembly including (a-1) recording heads having respective nozzle opening surfaces and (a-2) a head frame supporting the recording heads; (b) annular protrusions each of which is to be brought into contact with the head assembly, so as to surround the plurality of nozzles opening in the corresponding nozzle opening surface; (c) a supporting tray elongated in a supporting-tray longitudinal direction and supporting the annular protrusions; (d) a movement mechanism configured to move the head assembly and/or the supporting tray, and (e) a positioning pin projecting from a pin-located portion of the supporting tray. The pin-located portion is outside the annular protrusions, and is located in a center of the supporting tray in the supporting-tray longitudinal direction. The head frame has a positioning hole, into which the positioning pin is to be introduced upon contact of each annular protrusion with the head assembly. |
