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.

A liquid ejection device includes: a conveyance mechanism which conveys a recording medium in one direction; a plurality of liquid ejection heads each having an ejection face which has a plurality of ejection openings for ejecting liquid and faces the conveyance mechanism, the liquid ejection heads being arranged along the one direction; a plurality of wipers which respectively wipe the ejection faces; a holder which holds the wipers; a support which supports the holder; and a movement mechanism which moves the holder in a direction perpendicular to the one direction. The holder is displaceable in the one direction relative to the support. The holder has an intruder which intrudes into a gap between two liquid ejection heads adjacent to each other.

A capping mechanism selectively takes a capped state in which an ejection space opposing an ejection surface is covered or an uncapped state in which the ejection space is not covered. A controller is configured to: determine whether a first change of the capping mechanism from the capped state to the uncapped state occurred while air moisturized by a moisturization mechanism is being moved to the ejection space by a ventilator or not; and when a second change of the capping mechanism from the uncapped state to the capped state occurred after the first change occurred, control the ventilator to move the air moisturized by the moisturization mechanism to the ejection space when a first uncapped time is shorter than a first predetermined time, and control a discharger to discharge the liquid through ejection openings when the first uncapped time is not shorter than the first predetermined time.

A reciprocating apparatus includes a pair of guide members which extend in parallel with each other and in a first direction; a carriage which is reciprocateable in the first direction, supported and guided by the pair of guide members; and a carriage movement detector including (a) a sensor which is fixed to the carriage and (b) an encoder strip which extends in the first direction and which has sensible portions arranged in a lengthwise direction thereof and sensible by the sensor, such that a reciprocating movement of the carriage is detected based on sensing of the sensible portions by the sensor. The encoder strip is located between the pair of guide members in a second direction perpendicular to the first direction. The pair of the guide members are located on one of opposite sides of the carriage in a third direction perpendicular to the first and the second directions. The encoder strip is located on the other of said opposite sides of the carriage in the third direction.
