Abstract
PURPOSE:To minimize a take-up torque and smoothly wind a photosensitive element, etc. by providing a feeder roll and a take-up roll inside a drum body and installing a guide roller at a position near each one side of a discharge port and an intake port in a freely rotating fashion. CONSTITUTION:A feeder roll 7 and a take-up roll 8 are provided inside a drum body 1 equipped with a discharge port 4 and an intake port 5. At the same time, guide rollers 9, 10 are provided in a freely rotating fashion at a position at a position in the neighborhood of at least either of the afore-mentioned discharge port 4 and intake port 5. Following this procedure, a used photosensitive element 3 mounted around the external periphery is taken up and then a new photosensitive element 3 is mound around the external periphery of the body 1. Next, the said photosensitive element 3 is fed out from the guide roller 9, the discharge port 4, and a curvature contact part 16 along the external periphery of the body 1. After this process, it is wound up by the take-up roller 8 from the other curved part 1c through the intermediary of the guide roller 10.
