A medium tray (101) comprises a medium support (1) connected to a medium feeding section (100) of an image recording apparatus (200) and receiving record medium (P), and a medium guide (5) extending from the medium support (1) and supporting the record medium (P) such that an angle of a rear portion of the record medium (P) is changed. A lengthy record medium (P) having a length greater than the medium support (1) is supported by the medium guide (5) with the rear portion thereof directed at a different angle so that the length record medium (P) is loaded in the medium tray (101) without enlarging an area projecting from the image recording apparatus (200).
