PURPOSE:To copy an original of large size with a small-sized copying machine by clamping a contact reflection exposure type photosensitive body between a photosensitive body supporting member and an original feed roller, and moving and exposing the photosensitive body synchronously with the feed of an original. CONSTITUTION:The original feed roller 13 is provided facing the photosensitive body supporting member 3 in a housing 1 and the filmy photosensitive body 7 capable of contact reflection exposure and a film 10 for insulating are wound in contact between the member 3 and roller 13. When the original 2 is caught by the roller 13, the photosensitive body 7 and film 10 are conveyed synchronously through specific perforations while syncrhonizing with the speed of the original 2; and the contact reflection exposure is performed by the light source 5 of an exposure part 4 to form an electrostatic latent image on the photosensitive body 7, and the photosensitive body is teken on around a roll 9 through a development part 8 and a transfer paper 21. Thus, the small-sized device copies originals of large size. |
