A moving original exposure type of copying machine comprising, an original carrier reciprocatively moving on a machine body, a group of rollers conveying a photosensitive paper synchronously with the reciprocal movement of the original carrier, an image-forming station forming an image on a photosensitive paper, the group of photosensitive paper conveying rollers including a first pair of rollers located apart from and upstream of the image-forming station, holding therebetween and conveying a photosensitive paper, and including a second and a third pairs of rollers positioned adjacent to and upstream and downstream of the image-forming station, holding therebetween and conveying a photosensitive paper, the first rollers being provided with release means whereby a photosensitive paper held by the first rollers is released when the paper passes the image-forming station.

Photosensitive paper conveying device of a copying machine

An exposure-scanning apparatus in which an erect, equal-sized light image of an original document is focused on an image-receiving sheet. The apparatus comprises a transparent platen maintained stationary to support the original document. A scanning box is arranged to advance and then to return between first and second positions in parallel to the platen. An optical-exposure unit is arranged to move together with the scanning box. As the scanning box advances, the image-receiving sheet is advanced by means of a sheet-transport device in a direction the same as that of the scanning box at a speed twice that of the advance of the scanning box. A pair of push rollers are rotatably supported on the scanning box to push the image-receiving sheet onto the sheet-transport device at positions immediately before and after the light-image forming region in a direction of advance of the scanning box. The image-receiving sheet may be a photosensitive paper having a photoconductive surface.
