HOLDING STRUCTURE FOR FILM ON BACK LIGHT

PURPOSE:To simply hold a film with a single hand during the same operation by using a part for holding the film in common with a cover for fixing a translucent plate and deflecting the translucent plate by means of operation for setting up the film on a back light. CONSTITUTION:A step difference 11 is formed on a part adjacent to a cover 3 for a guide rack so that the translucent plate set up on its upper part can be deflected. When the translucent plate is pressed together with the film at the time of setting up the film on the translucent plate 2, the translucent plate 2 is deflected. When the film is inserted between the translucent plate 2 and the cover 3 under said status, the film is pressed and held by the spring back of the translucent plate 2. Consequently, the film can be surely held during the operation for setting up the film on the translucent plate 2.
