• a discharge port configured to discharge, in a discharge direction, the sheet on which the printing unit prints the image;
• a receiver having a first end portion and a second end portion and configured to stack the sheet discharged from the discharge port;
• a foot provided with a caster for moving a sheet storage device relative to the printing apparatus;
• a first supporting unit rotatably held by the foot and configured to move the first end portion relative to the discharge port;
• a second supporting unit held by the foot and configured to support the second end portion disposed at a position closer to the discharge port than a position of the first end portion, the second supporting unit being lower than the first supporting unit;
• and
• a leg unit provided between the first supporting unit and the second supporting unit with respect to the discharge direction, and attached to the foot so as not to rotate about the foot, wherein
• the receiver is deformed into a first form in which a part between the first end portion and the second end portion is supported by the leg unit and a second form in which the part is not supported by the leg unit.
