• the slide cover includes:
• an L-shaped cover main body formed by connecting at least a top plate covering the supply tray and a front plate covering a front side of the discharge space when the slide cover is disposed at the closing position;
• and
• a side cover which is rotatably connected to a top surface side of the cover main body, covers one of right and left sides of the discharge space when the side cover is disposed at the closing position, and is pushed up by interfering with the supply tray in a process of being slid from the closing position to the open position.
