Abstract
A feeder apparatus for feeding microfilm jackets to a printer, one at a time from a stack of jackets. The feeder apparatus comprises a tray-like housing, a weight assembly and a brake assembly. The weight assembly includes a pair of pivotally mounted weights which rest on the stack of jackets to create friction between the bottom jacket and a printer feed roller. The brake assembly is used to hold back all but the bottom jacket, as the bottom jacket is transported by the printer feed roller.
Claims14
An apparatus for feeding microfilm jackets to a printer, comprising:
- a housing for receiving a stack of microfilm jackets;
- a weight assembly for proving a constant force on said stack of microfilm jackets;
- and
- a brake assembly for preventing more than one microfilm jacket to be fed from the stack at the same time.
A microfilm jacket feeder for a printer having a printer drive roller, said microfilm jacket feeder comprising:
- a housing mounted proximate said printer drive roller, said housing configured to receive a stack of microfilm jackets;
- a pair of weights, said pair of weights adapted to rest upon said stack of microfilm jackets in said housing, wherein said weights provide a constant load on said stack of microfilm jackets to provide sufficient friction between said printer drive roller and a microfilm jacket in contact with said printer drive roller;
- and
- a brake roller mounted adjacent said printer drive roller and adapted to be biased against said stack of microfilm jackets, wherein said brake roller prevents all but said microfilm jacket in contact with said printer drive roller from being feed into said printer.
An apparatus for feeding microfilm jackets to a printer, comprising:
- a housing for receiving a stack of microfilm jackets;
- a weight assembly for proving a force on said stack of microfilm jackets;
- and
- a brake assembly for preventing more than one microfilm jacket to be fed from the stack at the same time, the brake assembly comprising a brake roller which receives a braking force created by thrust washers.
A microfilm jacket feeder for a printer having a printer drive roller, said microfilm jacket feeder comprising:
- a housing mounted proximate said printer drive roller, said housing configured to receive a stack of microfilm jackets;
- a pair of weights, said pair of weights adapted to rest upon said stack of microfilm jackets in said housing, wherein said weights provide a constant load on said stack of microfilm jackets to provide sufficient friction between said printer drive roller and a microfilm jacket in contact with said printer drive roller;
- and
- a brake roller mounted adjacent said printer drive roller and adapted to be biased against said stack of microfilm jackets, wherein said brake roller prevents all but said microfilm jacket in contact with said printer drive roller from being feed into said printer, wherein the brake roller receives a braking force created by thrust washers.
