An apparatus is provided that may offer functionalities including printing, scanning and/or copying. The apparatus may include a manual sheet feeding tray disposed at the rear of the apparatus. The height of the sheet feeding tray might not exceed a height of the apparatus, allowing use of the apparatus in spaces having smaller depths. The apparatus may include a sheet guide configured to move in conjunction with the movement of the tray. In some arrangements, a surface of the sheet feeding tray may differ in height between lateral edges of the tray and a central portion. This difference may cause a sheet to be curved in a lateral direction, rendering the sheet more inflexible in a longitudinal direction. According to other aspects, a depressed portion of the tray may match a protrusion extending from the guide in shape such that the two portions may mate in a retracted position.
