A photographic-materials dispenser, comprising:
- a housing having end walls;
- a shaft rotatably journalled in said end walls upon which to mount a roll of photographic material;
- a drive roller journalled in said end walls;
- a driven roller journalled in said end walls, in juxtaposition, and mutually nipping engagement, with said drive roller;
- motor means mounted in said housing;
- and
- a power train supported within said housing, drivenly coupled to said drive roller to drive said drive roller in powered rotation, to cause said drive roller to drive said driven roller, whereby, sheet material unrolled from said shaft, and introduced between said rollers, is drivenly payed out from said shaft and between said rollers;
- wherein
- said housing further has a hinged cover for enclosing and exposing said shaft and rollers;
- said walls and said cover have means cooperative for forming a barrier to the admittance of light into said housing;
- said walls each (a) a substantially horizontal top rim and a substantially vertical, front rim, (b) recessed shoulders adjacent to said rims, upon which, and against which, to receive said cover, and (c) grooves formed between said shoulders and said rims;
- said cover has continuous, blade-like projections which, upon said cover being hingedly received upon and against said shoulders, enter into said grooves to form the aforesaid light barrier;
- said motor means comprises (a) an electrical motor, (b) electrical lines coupled to said motor at one end, and having a line plug at the opposite end, and (c) electrical switching means, intermediate the ends of one of said lines, operative for inhibiting, and for permitting, electrical power communication with said motor;
- said housing further has a front wall, and a sot formed therein for accommodating a pay-out of sheet material therethrough;
- said housing also has a land formed therewithin, adjacent to said slot, upon which sheet material slides during pay-out thereof;
- said housing further has a ridge formed therein, extending lengthwise between said end walls, in adjacency to said land;
- and further including
- means slidably engaged with said ridge for traverse therealong, and having means for severing sheet material;
- wherein
- said switching means comprises normally-open, power-interrupting, control switches, electrically interposed in one of said lines, and physically disposed in adjacency to and at opposite ends of said ridge, said control switches each having a switch-closing, pivotable follower extending therefrom;
- and
- said severing means has means engageable with said followers, upon slidable traverse thereof, along said ridge, to one of said opposite ends of said ridge, for pivotably displacing said follower, at said one end, to close such associated control switch thereat.
