• wherein the fixing tray comprises:
• a first fixing guide protruding from the fixing tray in the first direction from the seating portion and configured to support a first end of the protective film;
• and
• a second fixing guide protruding from the fixing tray in a second direction that is opposite to the first direction and configured to support a second end of the protective film, and
• wherein the first fixing guide comprises:
• a guide block to which an end of the protective film is fastened, the guide block configured to be tilted about a rotation axis in response to a change in tension applied to the protective film from movement of the roller;
