A document handling apparatus/copy sheet processor/finishing apparatus arranged as an integrated system to produce bound copy sheets at high speed but with minimum mechanical activity by double exposing each document sheet, producing successive copy sheets in accordance with the exposure, distributing the successive copy sheets alternately into receiving trays and utilizing a set transport for each of the trays to bring copy sets alternately to a single point binding device.

Very high speed duplicator with finishing function using dual copy set

A very high speed, fully automated reproduction system is disclosed having a document handling apparatus, copy sheet processor, and a finishing station. For very high reproduction rates, post-collation of copy sheets into copy sets is utilized. In this arrangement the document apparatus is arranged to expose each document sheet of a document a predetermined number of times before a succeeding document sheet is brought into exposure position so that for each complete circulation of all the document sheets, the document would have been copied a number of times equal to said predetermined number. A sorter bin array having a number of bins equal to said predetermined number is arranged to collate the resultant copy sheets into corresponding copy sets. The copy sets are removed from the bin array for stapling and stacking or non-stapling and stacking.

Very high speed duplicator with finishing function

A reproduction machine for making either single sided or duplex copies, and incorporating automatic document handler and sorter for handling original documents being copied and copies made. To enable copy quality to be checked, either when the machine is stopped or in the midst of a copy run, a sample copy is provided for. Where the sample copy is selected during a copy run, an accommodation in copy billing rate is made.

Sample copy system for xerographic reproduction machine

A reproduction machine for making two-sided or duplex copies. When there is an odd number of simplex original documents to be copied in the duplex mode, the last copy sheet bears an image only on one side. The present invention provides a control system for operating various machine components in response to such an occurrence in order to optimize the throughput capability of the machine.

Automatic duplex control system for a reproduction machine

An imaging lens system for electrostatic type reproduction machine or copiers utilizing a zoom lens effective to provide, within the magnification limits of the lens, infinitely variable image sizes. A control is provided to pre-set the lens to automatically give, upon actuation at least one preselected image size, with an override control to enable the lens to be set to provide any image size regardless of pre-set conditions. Further controls are provided for the machine nonimage erase mechanism to automatically compensate for changes in the image borders brought about by changes in image size due to resetting of the zoom lens. For this purpose, an infinitely variable edge fadeout apparatus is provided incorporating movable shutters to vary the effective size of the edge erasure slots in correspondence with image size together with timing controls for changing the operational timing of the pitch fadeout lamp in response to changes in image size upon resetting of the zoom lens. Further controls enable the critical positioning of the image produced by the zoom lens on the photosensitive member to be adjusted to assure that the image, whatever the size, is optimally positioned on the copy produced with other controls to enable the image, whatever the size produced by the zoom lens, to be physically moved or offset on the copy.
