Abstract

Abstract A copying machine of the Electrofax type having a stationary horizontal transparent support for receiving manuscript to be copied and a carriage mounted for horizontal movement beneath the transparency to effect optical scanning of the manuscript. The carriage supports means for feeding copy paper vertically past an image-receiving zone, a mirror which projects an image from the manuscript horizontally toward the image-receiving zone, lens means between the mirror and the image-receiving zone for focusing the image on the surface of the copy paper, a toner receptacle and means for feeding the copy paper therethrough after exposure thereof. Means are provided for moving the carriage horizontally in exact synchronism with vertical movements of the copy paper whereby a panoramic image from the manuscript is applied to the copy paper. The carriage-moving means includes a pulley mounted upon and rotated jointly with a paper feed roll and a traction cable wrapped about the pulley and adapted to be connected to opposite ends of the machine. Means are provided for tightening the cable whereby rotation of the pulley causes the pulley to rotate along the cable and thus move the carriage in synchronism with the paper feed roller.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 189 words
In an electrophotographic copying machine, a stationary support having a horizontal transparent plate adapted to receive manuscript to be copied in facedown position thereon, a carriage mounted for horizontal movement relative to said support beneath said transparent plate to effect linear panoramic scanning of said manuscript, said carriage having an image-receiving zone, roller means mounted on said carriage for feeding copy paper through said carriage past said image-receiving zone, optical means mounted on said carriage for receiving a panoramic image from said manuscript and projecting the same to said imagereceiving zone, means driven directly from said paper feed roller means for moving said carriage horizontally through forward and return strokes in accurate synchronism with movements of said copy paper to reproduce an image of said manuscript on said copy paper and return the carriage to initial position means mounted on said carriage adjacent to said image-receiving zone containing electrophotographic toner material, and means for directing said copy paper emerging from said image-receiving zone directly into surface contact with said toner material and for delivering the same from the machine at the conclusion of the return stroke of said carriage.
Claim 2
Dependent Claim 189 words
In an electrophotographic copying machine, a stationary support having a horizontal transparent plate adapted to receive manuscript to be copied in facedown position thereon, a carriage mounted for horizontal movement relative to said support beneath said transparent plate to effect linear panoramic scanning of said manuscript, said carriage having an image-receiving zone, roller means mounted on said carriage for feeding copy paper through said carriage past said image-receiving zone, optical means mounted on said carriage for receiving a panoramic image from said manuscript and projecting the same to said imagereceiving zone, means driven directly from said paper feed roller means for moving said carriage horizontally through forward and return strokes in accurate synchronism with movements of said copy paper to reproduce an image of said manuscript on said copy paper and return the carriage to initial position means mounted on said carriage adjacent to said image-receiving zone containing electrophotographic toner material, and means for directing said copy paper emerging from said image-receiving zone directly into surface contact with said toner material and for delivering the same from the machine at the conclusion of the return stroke of said carriage.
Claim 3
Dependent Claim 37 words
A copying machine according to claim 1 wherein copy paper is fed vertically past said image-receiving zone and wherein said optical means projects said panoramic image horizontally to said vertically moving copy paper at said image-receiving zone.
Claim 4
Dependent Claim 36 words
A copying machine according to claim 1 wherein said copy paper feeding roller means is motor driven and wherein said carriage-moving means comprises a drive wheel fixed to said paper feed roller means for rotation therewith.
Claim 5
Dependent Claim 24 words
A copying machine according to claim 1 wherein said optical means comprises a mirror positioned to reflect said panoramic image toward said image-receiving zone.
Claim 6
Dependent Claim 172 words
In an electrophotographic copying machine, a support having a horizontal transparent plate adapted to receive manuscript to be copied in facedown position thereon, a carriage mounted for horizontal movement relative to said support beneath said transparency to effect linear panoramic scanning of said manuscript, roller means for feeding copy paper through said carriage past an image-receiving zone, optical means on said carriage for receiving a panoramic image from said manuscript and projecting the same to said image-receiving zone, means driven from said paper feed roller means for moving said carriage horizontally in accurate synchronism with movements of said copy paper to reproduce an image of said manuscript on said copy paper, said feed roller comprising a pulley, a traction cable having a portion thereof wrapped around said pulley and its ends extending to opposite ends of said machine, and means for tightening said cable whereby rotation of said pulley causes the pulley to rotate along said cable and thereby move said carriage horizontally in accurate synchronism with said copy paper feed roller.
Claim 7
Dependent Claim 172 words
In an electrophotographic copying machine, a support having a horizontal transparent plate adapted to receive manuscript to be copied in facedown position thereon, a carriage mounted for horizontal movement relative to said support beneath said transparency to effect linear panoramic scanning of said manuscript, roller means for feeding copy paper through said carriage past an image-receiving zone, optical means on said carriage for receiving a panoramic image from said manuscript and projecting the same to said image-receiving zone, means driven from said paper feed roller means for moving said carriage horizontally in accurate synchronism with movements of said copy paper to reproduce an image of said manuscript on said copy paper, said feed roller comprising a pulley, a traction cable having a portion thereof wrapped around said pulley and its ends extending to opposite ends of said machine, and means for tightening said cable whereby rotation of said pulley causes the pulley to rotate along said cable and thereby move said carriage horizontally in accurate synchronism with said copy paper feed roller.
Claim 8
Dependent Claim 197 words
In an electrophotographic copying machine, a support having a horizontal transparent plate adapted to receive manuscript to be copied in facedown position thereon, a carriage mounted for horizontal movement relative to said support beneath said transparency to effect linear panoramic scanning of said manuscript, roller means for feeding copy paper through said carriage past an image-receiving zone, optical means on said carriage for receiving a panoramic image from said manuscript and projecting the same to said image-receiving zone, means driven from said paper feed roller means for moving said carriage horizontally in accurate synchronism with movements of said copy paper to reproduce an image of said manuscript on said copy paper, said roller means being motor driven and said carriage moving means comprising a drive wheel fixed to said paper feed roller means for rotation therewith, said drive wheel comprising a pulley, a traction cable having a portion thereof wrapped around said pulley and its ends extending to opposite ends of said machine, and means for tightening said cable whereby rotation of said pulley causes the pulley to rotate along said cable and thereby move said carriage horizontally in accurate synchronism with said copy paper feed roller.
