发明名称 Device for feeding photosensitive material
摘要 A feeding device for photosensitive materials arranged between the printing unit and the developing unit of a photographic processor. A photosensitive material supplied from the printing unit is smoothly transported on the surface of a feed drum which intermittently rotates, synchronized with the speed of development at the developing unit. While the web is being fed, its leading and tail ends are pressed by presser bars against the drum surface. Also provided is a loop formation plate adapted to tilt gradually downwardly under the increasing weight of the photosensitive material lying thereon to allow it to slide down smoothly. Thus, the web is formed into a loop while hanging. The material is fed straight without meandering owing to an anti-meandering mechanism including a pair of restrictor frames for restricting the material from moving sideways and a roller for pushing the material into between the restrictor frames when it is in its operative position. Thus the photosensitive material is smoothly fed from the printing unit to the developing unit without suffering any damages on its surface and without wasting time.
