PURPOSE:To obtain an original supply device which copies an original group in order from the first page and attains easily single or double face copies from single face originals, single or double face copies from both face copies, and these recycle copies, by providing a passage through which originals are sent from a tary to an exposure part and are inverted even times and are returned to the tray, a passage through which originals sent from the tray to the exposure part are inverted odd times and are returned to the tray, and a passage through which originals are inverted once for the purpose or exposing rear faces of exposed originals. CONSTITUTION:An original D carried by pinch rollers 5A and 5B is sent onto a contact glass 7 and is transferred to feeding rolls 9-11; and when a sensor 16 detects the front end of the original D, rotation of feeding rolls is stopped, and the original D is stopped in a prescribed position on the glass 7. The original D is exposed to light in this position and is carried in the direction of a guide 12 again by feeding rolls 9-11. When the rear end of the original D is detected by the sensor 16, a branching plate 15 is switched, and the carried original D is stopped in the prescribed position on the glas 7 by reversing feeding rolls 9-11. In this state, the rear face of the original D whose front face is exposed beforehand is exposed to light. The original D after exposure is inverted along both branching plates 15 and 20 and is introduced into a guide 17 and is ejected onto an original tray 1 by feeding rolls 22A and 22B and is placed on originals D exposed to light before. |
