Abstract

Abstract Original documents are recycled through a photocopy machine a preselected number of times along a selected one of a plurality of paths of different lengths as determined by the length of the original document being recycled. The plurality of paths include a single copy document path and a first and second recycling document path. Each of the feed paths are so arranged that there is a portion which is common to the single copy feed path, the relatively long first recycling document path and the relatively short second recycling document path. The common portion is traversed along all of these paths by an original document regardless of which of the feed paths the original document initially or ultimately traverses, thereby necessitating only a single set or bank of control switches for controlling the several operating functions of the photocopy machine. Control apparatus which is located in the common portion is situated in advance of the illuminating station and guides are positioned for directing a document to be copied into the common portion prior to the document passing the control apparatus.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 311 words
A photocopy machine having: A. guide and transport means defining an illuminating station for an original document to be copied and an exposing station for copy paper to be imaged and for transporting an original document and copy paper through their respective stations, B. means for simultaneously illuminating an original document and for projecting an image of indicia thereon onto copy paper as the original document and copy paper are fed through their respective stations by said transport means, C. means for feeding copy paper from a supply thereof, D. switch means responsive to the movement of a document therepast for actuating said illuminating means and said copy paper feeding means, and E. means for directing an original document past said illuminating station for making a single copy of the document and for recycling original documents of varying length past said illuminating station along a selected one of a plurality of paths of different length as determined by the length of an original document for making a plurality of copies of the original document, said document directing and recycling means comprising a. means defining a single copy document path, a first recycling document path and a second recycling document path having a shorter effective length than said first recycling document path, each of said recycling document paths having a portion in common with said switch means and said illuminating station being located in said common portion of said recycling document paths, and said switch means being located therein in advance of said illuminating station, b. guide means for directing a document to be copied into said common portion of said recirculating document paths at a location in advance of said switch means, and c. control means operable to cause a document to be directed along a selected one of said recycling document paths in accordance with the length of the document.
Claim 2
Dependent Claim 311 words
A photocopy machine having: A. guide and transport means defining an illuminating station for an original document to be copied and an exposing station for copy paper to be imaged and for transporting an original document and copy paper through their respective stations, B. means for simultaneously illuminating an original document and for projecting an image of indicia thereon onto copy paper as the original document and copy paper are fed through their respective stations by said transport means, C. means for feeding copy paper from a supply thereof, D. switch means responsive to the movement of a document therepast for actuating said illuminating means and said copy paper feeding means, and E. means for directing an original document past said illuminating station for making a single copy of the document and for recycling original documents of varying length past said illuminating station along a selected one of a plurality of paths of different length as determined by the length of an original document for making a plurality of copies of the original document, said document directing and recycling means comprising a. means defining a single copy document path, a first recycling document path and a second recycling document path having a shorter effective length than said first recycling document path, each of said recycling document paths having a portion in common with said switch means and said illuminating station being located in said common portion of said recycling document paths, and said switch means being located therein in advance of said illuminating station, b. guide means for directing a document to be copied into said common portion of said recirculating document paths at a location in advance of said switch means, and c. control means operable to cause a document to be directed along a selected one of said recycling document paths in accordance with the length of the document.
Claim 3
Dependent Claim 67 words
A photocopy machine as defined by claim 1 wherein said control means includes gating means operable to cause an original document to move along said first or second recycling document path, said control means being operable to cause said gating means to direct an original document partaking of its firSt recirculating cycle to always move along the longer one of said first or second recycling document paths.
Claim 4
Dependent Claim 75 words
A photocopy machine as defined by claim 2 wherein said control means further includes sensing means for measuring the length of an original document passing through said first recycling document path and for actuating said control means to set said gating means to cause an original document to move along said first or second recycling document path in accordance with the measured length of the document on recirculating cycles subsequent to said first recirculating cycle.
Claim 5
Dependent Claim 42 words
A photocopy machine as defined by claim 3 wherein said sensing means comrpises said first named switch means and another switch means spaced apart from said first switch means a distance greater than the maximum length of said second recycling document path.
Claim 6
Dependent Claim 112 words
A photocopy machine as defined by claim 2 wherein said control means includes said first named switch means and a second switch means both operatively disposed along said first recycling document path, one of said switch means being spaced from a second one of said switch means, whereby said spaced switch means are connected to control said gating means to pass said original along said longer one of said recycling document paths when said original simultaneously contacts both said spaced switch means at least momentarily and to pass said original along said shorter one of said recycling document paths when said original contacts both said spaced switch means one at a time.
