ABSTRACT:
An apparatus is disclosed for receiving sheets from the discharge portion of an electrostatic copy machine, which apparatus receives, stacks and collates the sheets as desired. The apparatus can be electrically independent of the copier and is attached thereto by simple hanger and bracket arrangements. The apparatus includes a plurality of trays which are moved past the discharge opening of the copier, and which are controlled and arranged, selectively to receive (1) a plurality of sheets in each tray; (2) a single copy of each sheet in each of several trays; or (3) a number of identical sheets in one tray and a differing number of other sheets in successive trays. The apparatus can collect, collate, and sort the sheets while the trays are moving in one direction past the copier discharge opening, as well as when the trays are moving past it in the other direction. The apparatus will automatically conclude its sorting cycle whenever there is an extra-ordinary delay in the discharge of the sheets from the copier. In another embodiment, utilizing an appropriate connection to the copier, the apparatus can be arranged to complete its collating cycle only when the exact number of desired copies has been sorted (i.e. independently of any misfeed, delay, or jam-up in the copier operation).
