Abstract

Abstract A mechanism for feeding originals to a copier apparatus so that the apparatus in one mode of operation automatically makes copies of related documents and delivers such copies in a predetermined collated arrangement and in another mode of operation makes copies of a plurality of unrelated documents, each of which may require a different number of copies, and automatically delivers the desired number of copies of each unrelated original. Each original is placed in a semi-rigid carrier device and the carriers are appropriately stacked near the copier apparatus. A reciprocating pick-up arm removes the carriers from the stack, one by one, delivers them to the copier apparatus exposure window and returns them to the stack in order for recirculation, if desired, in the first mode of operation. In the second mode of operation, each carrier has an encoding device for indicating the numbers of copies desired and the reciprocating pick-up arm removes each carrier from the stack for delivery to the exposure window, one at a time, at which location a decoding device decodes the encoded information and permits the copier apparatus to make the desired number of copies before removing that original and delivering the next original for copying.
