• and
• a supporting column arranged at a lateral side of the discharge unit for supporting the image reader and formed with a discharge port through which a sheet is discharged to the discharge tray,
• wherein:
• the front end of the image reader is located at a position more backward than the front end of the discharge tray while the front end of the supporting column is located substantially at the same position as that of the discharge tray;
• the operation unit is arranged to take up a part of a space before the image reader and above the discharge tray;
• and
• a clearance enabling a part of the discharge tray to be seen when viewed from above is formed between the operation unit and the supporting column.
