フイルム巻取りドラム。 The drum has a cylindrical shape and has an opening in the direction of the outer circumferential axis, a supply roll on which a new band-shaped photoreceptor film is wound inside the drum, and a take-up roll for winding and collecting the photoreceptor film that has reached the end of its service life. The end of the photoreceptor film is passed from the supply roll through the opening and wound around the drum's outer circumferential surface, and then fixed again to the take-up roll inside the drum through the opening, thereby extending the life of the photoreceptor film on the drum's outer circumferential surface. A photoreceptor film winding drum configured to take up and collect the photoreceptor film one after another has an engaging member at the end of the photoreceptor film that engages with the take-up roll, and the take-up roll has an engaging member in the direction of the outer circumferential axis. 1. A photoreceptor film winding drum characterized in that an engagement groove for holding the photoreceptor film is provided, and the end of the photoreceptor film and the winding roll can be attached and detached from each other.
