Abstract:
A sheet tray unit includes a particular feed tray configured to hold one or more sheets therein, and a discharge tray disposed on the particular feed tray and configured to receive a discharged sheet. The discharge tray includes a first discharge tray portion, a second discharge tray portion, and a third discharge tray portion. The first discharge tray portion is configured to support the second discharge tray portion such that the second discharge tray portion selectively slides in a first direction and in a second direction, which is opposite and substantially parallel to the first direction. The second discharge tray portion is configured to support the third discharge tray portion such that the third discharge tray portion selectively slides in the first direction and in the second direction. The first discharge tray portion includes a stopper configured to limit the third discharge tray portion from sliding in the first direction beyond a predetermined position.
