ABSTRACT:
In the embodiment depicted, the apparatus comprises a housing having an access door and a materials-discharging opening. Within the housing is a support structure for receiving a plurality of cassettes of photographic sheet material, such as photosensitive paper and negative stock. To the support structure are mounted a plurality of platforms which grip the cassettes, and a plurality of chutes for conveying the sheet materials from the cassettes to the discharging opening. Rollers intrude into the chutes and define nips which grasp the sheet material and a handwheel fixed to one roller of pairs thereof is used to advance the sheet material along the chutes. A bladed cutter is reciprocatingly supported by the housing, in immediate adjacency to the discharging opening, for severing thereat lengths of sheet material which are passed therethrough.
