Abstract
Disclosed is a reel for winding photosensitive film (6) which stabilizes the winding shape of the film and minimizes the deformation of a photosensitive layer caused by the winding tension. The winding reel is easily carried and stored, and has a sufficient strength to stand against the winding tension of the wound photosensitive film. The user can check the amount of the wound photosensitive film. The winding reel has a cylindrical reel member (10) for winding the photosensitive film around a circumference thereof with a predetermined tension, and flange members (20, 30) detachably coupled to both sides of the reel member. The flange members (20, 30) have inner surfaces which are disposed in opposition to each other and are closed to both edges of the photosensitive film wound around the reel member. By the winding reel, it is possible to wind the photosensitive film around the reel member (10) with a proper tension. Since a width of the photosensitive film (6) is constantly maintained, the edge portion of the photosensitive film (6) is prevented from deforming. The reel member (10) is easily carried or stored. Since the flange members (20, 30) have plural windows (40, 42), it is possible to check the amount of the wound photosensitive film (6) with the naked eye, so it is very convenient to use the winding reel.
