1. An ink jet recording apparatus, comprising:
a media tray configured to support a recording medium; a roller pair comprising a first roller and a second roller opposite the first roller, a state of the roller pair being switched between a first state in which the first roller and the second roller nip a sheet and a second state in which the first roller and the second roller are spaced apart from each other by a greater distance than in the first state and capable of nipping the media tray; a recording device comprising a plurality of nozzles and disposed downstream of the roller pair in a conveying direction in which the sheet is conveyed, the recording device being configured to eject ink droplets from the plurality of nozzles onto one of the sheet and the recording medium supported on the media tray; a plurality of lower contact portions disposed downstream of a sheet nipping position of the roller pair in the conveying direction, the plurality of lower contact portions being arranged spaced apart from each other in a widthwise direction intersecting the conveying direction, the plurality of lower contact portions being configured to contact a lower side of the sheet; and at least one upper contact portion disposed between the sheet nipping position of the roller pair and the plurality of nozzles in the conveying direction, the at least one upper contact portion being disposed between adjacent two of the plurality of lower contact portions in the widthwise direction, the at least one upper contact portion being configured to contact an upper side of the sheet, the at least one upper contact portion being configured to cooperate with the plurality of lower contact portions to corrugate the sheet, the media tray comprising a downstream edge portion in a tray inserting direction in which the media tray is inserted, the downstream edge portion being provided with at least one inclined portion inclining obliquely upward toward an upstream side in the tray inserting direction, the at least one inclined portion being configured to contact the at least one upper contact portion to move the at least one upper contact portion upward. |
