Microfiche cartridge and transport apparatus

Claim 1

A microfiche cartridge and transport apparatus for moving a selected microfiche onto a receiving platen of a microfiche viewer, including, in combination: a. an open top frame structure; b. a box shaped cartridge having a series of elongated rectangular pockets in a stacked array, one above the other, with exposed front openings, each pocket being dimensioned to receive in its front opening a single microfiche, opposite sides of said box shaped cartridge having vertical cut-out channels intersecting opposite sides of said pockets to expose opposite edge portions of each microfiche when stored in the pockets, said box shaped cartridge being receivable in the open top of said frame for guided movement in an up and down direction; c. a first reversible motor means for raising and lowering said cartridge within said frame in discrete increments corresponding to the vertical spacing between adjacent pockets; d. friction wheels mounted for rotation about vertical axes and lying in a horizontal plane on opposite sides of said frame, peripheral portions of said wheels being received in said cut-out channels to engage the opposite edges of a microfiche contained in a pocket positioned in said horizontal plane; e. a conveyor means including drive rollers supported by said frame at the front opening of that pocket in said horizontal plane, said conveyor means extending at its far end to said platen and including a return transport initiating means in the form of a friction roller overlying but not normally engaging a trailing edge portion of a microfiche when fully positioned on said platen; and, f. a second reversible motor means for rotating said friction wheels, drive rollers and said friction roller whereby energization of said first motor means to move said cartridge in an up or down direction positions a selected pocket and its associated microfiche in said horizontal plane, energization of said second motor means in one direction transporting said microfiche from said pocket onto said conveyor means and onto said platen, and energization of said second motor means in a reverse direction causing said friction roller to engage said microfiche and feed it back onto the main portion of said conveyor means for return to said pocket by said main drive rollers and friction wheels.
