ABSTRACT:
My invention comprises a large capacity combined magazine and sheet feeder for copying machines, in which the sheet being fed is brought to feeding level by a spring-powered mechanical servomechanism. The assembly is adapted to be substituted for a small capacity cassette on an existing copy machine and to employ the power and logic of the existing machine to feed sheets from the large capacity assembly in proper synchronized relationship. This is accomplished by a power take-off from the copy machine with which the improved magazine is being used, which power take-off can be installed without altering the original machine. The large capacity unit then feeds sheets to the copy machine as if the original small capacity cassette were being used. The magazine is adapted to handle sheets of various lengths on which copies are to be made. The action of the lifting springs is damped by an inertial damper which controls the rate of upward movement of the paper supporting platform which is constrained to move parallel to itself by a parallel motion linkage.
