Abstract
Abstract A copier/duplicating system producing finished sets of copies from documents fed and copied in repeated cycles including a stapling assembly for collecting and stapling copy sheets into booklets and a side stacking assembly for grouping sheets into separately identifiable stacks. A control logic enables either stapling the sheets or side stacking the sheets at the option of a machine operator.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
In a copier/duplicator system in which documents are advanced from a supply source to a platen for copying thereof and then returned to the supply source in repeated cycles, improved apparatus for producing collated sets of copies comprising collection means to assemble and register copy sheets transported along a predetermined path, means to staple said sheets to form a set upon a receipt of discrete signals, tray means located downstream of said collection means to receive each stapled copy set advanced from said collection means, side stacking means associated with said tray means operative to move sheets transported along a predetermined path iNto offset identifiable stacks upon receiving discrete signals, and logic means to actuate the collection means and staple means, and, alternatively, said side stacking means depending on whether stapling or offset stacking of sheets is desired.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
125 words
An improved high speed automatic system of printing booklets from percollated documents comprising means for feeding documents in seriatim toward an exposure station of a copying machine for copying thereof and then returning the documents in precollated order to their original position, means for electrostatically copying each document onto a set of copy sheets in timed order, means for advancing the copy sheets toward a finishing station for stacking in a collated set in corner registration, means for stapling the set of copy sheets into a bundle corresponding to the documents being copied, and means for ejecting each bundle into a collection zone, and control logic means for supplying signals to the aforementioned means in timed order until the desired number of booklets is produced.
Claim 4
Dependent Claim
125 words
An improved high speed automatic system of printing booklets from percollated documents comprising means for feeding documents in seriatim toward an exposure station of a copying machine for copying thereof and then returning the documents in precollated order to their original position, means for electrostatically copying each document onto a set of copy sheets in timed order, means for advancing the copy sheets toward a finishing station for stacking in a collated set in corner registration, means for stapling the set of copy sheets into a bundle corresponding to the documents being copied, and means for ejecting each bundle into a collection zone, and control logic means for supplying signals to the aforementioned means in timed order until the desired number of booklets is produced.
Claim 5
Dependent Claim
53 words
A system according to claim 2 wherein said means for electrostatically copying the documents includes illumination means for forming a latent electrostatic image on a moving photoreceptor by flash exposure thereof, means for developing the image, and means for transferring the developed image onto paper moved in timed relation with the moving photoreceptor.
Claim 6
Dependent Claim
125 words
An improved high speed automatic system of producing separately identifiable stacks of collated copies from precollated documents comprising means for feeding the documents in seriatim toward an exposure station of a copying machine for copying thereof before returning them to their original position in precollated order, means for electrostatically copying the documents onto copy sheets and advancing the copy sheets toward a finishing station in order, means positioned at the finishing station for side stacking the copy sheets first to one side and then the other to form offset identifiable bundles, each bundle being collated in order corresponding to the documents being copied, and control means for continuously repeating the aforementioned steps in timed order until the desired number of collated offset stacks is produced.
Claim 7
Dependent Claim
125 words
An improved high speed automatic system of producing separately identifiable stacks of collated copies from precollated documents comprising means for feeding the documents in seriatim toward an exposure station of a copying machine for copying thereof before returning them to their original position in precollated order, means for electrostatically copying the documents onto copy sheets and advancing the copy sheets toward a finishing station in order, means positioned at the finishing station for side stacking the copy sheets first to one side and then the other to form offset identifiable bundles, each bundle being collated in order corresponding to the documents being copied, and control means for continuously repeating the aforementioned steps in timed order until the desired number of collated offset stacks is produced.
Claim 8
Dependent Claim
53 words
A system according to claim 4 wherein said means for electrostatically copying the documents includes illumination means for forming a latent electrostatic image on a moving photoreceptor by flash exposure thereof, means for developing the image, and means for transferring the developed image onto paper moved in timed relation with the moving photoreceptor.
