ABSTRACT:
In cutting a film into individual screens and in fitting the screens onto the slide mounts, the positions for cutting the film are correctly set so that the film can be cut easily and quickly. For this purpose, holes are perforated in an opposing manner in both side portions of the film in a direction in which it is fed. The film is loaded into the camera, and a line L connecting the centers of the holes is brought into agreement with the center line of a gap portion between the screens. The film is divided into individual screens when it is cut using a pair of scissors along the lines L that connect the holes of the film. The ends of the holes in the direction of feed are semicircularly formed. Therefore, if the film divided into individual screens is brought into engagement with the positioning pins of the slide mount, semicircular portions of the holes and the positioning pins are fitted to each other, and the film is correctly fitted onto the slide mount.
