Abstract
Abstract An automatic original feed attachment for mounting on conventional electrophotographic duplicating machines comprising: a first section which is connected to the machine having a tray for holding a stack of originals to be duplicated and a feed system for removing the originals in sequence from the tray; a second section pivoted to the first section and having an endless belt which passes over the copying position of the machine and feeds originals from the first section to the copying position and holds them there during copying; and a third section connected to the second section and having an original receiving tray and a system for removing originals after copying and reversing their feed path before delivery to the receiving tray. The receiving tray mounting permits it to be dropped from its normally inclined position to rest on the second section and the second section may be pivoted up from the copying position to permit free access to the original receiving glass plate for individual copying when the present attachment is not being used.

Claim 1
Independent Claim
287 words
An automatic original feed device for mounting on electrophotographic duplicating machines comprising: a. an original stand-by section connected to said machine at one side of the copying Position and including: i. an original rest tray; ii. separating means for feeding originals from said original rest tray in sequence; and iii. pivot means; b. an original conveying and holding section having a flat upper surface thereon and pivotable on said pivot means for resting on the copying position on said machine adjacent said stand-by section and including: i. first conveying means for conveying each of the originals fed from said original stand-by section to the copying position on the machine; and ii. means for holding each original in said copying position during copying; and c. an original ejecting section disposed on the opposite side of the copying position from said original stand-by section and including: i. second conveying means for conveying each original from said copying position after being copied; ii. an original receiving tray upwardly inclined with respect to said copying position in the direction of said original rest tray and disposed above said original conveying and holding section for receiving each original conveyed thereto by said second conveying means, said tray having a flat undersurface thereon; and iii. mounting means for pivoting said receiving tray from said inclined position to a rest position with its flat undersurface on the flat upper surface of said original conveying and holding section; the original conveying and holding section and the original ejecting section being connected to each other and pivotable as a unit about said pivot means on said stand-by section so as to permit access to the copying position of the duplicating machine without removing the device therefrom.
Claim 2
Dependent Claim
287 words
An automatic original feed device for mounting on electrophotographic duplicating machines comprising: a. an original stand-by section connected to said machine at one side of the copying Position and including: i. an original rest tray; ii. separating means for feeding originals from said original rest tray in sequence; and iii. pivot means; b. an original conveying and holding section having a flat upper surface thereon and pivotable on said pivot means for resting on the copying position on said machine adjacent said stand-by section and including: i. first conveying means for conveying each of the originals fed from said original stand-by section to the copying position on the machine; and ii. means for holding each original in said copying position during copying; and c. an original ejecting section disposed on the opposite side of the copying position from said original stand-by section and including: i. second conveying means for conveying each original from said copying position after being copied; ii. an original receiving tray upwardly inclined with respect to said copying position in the direction of said original rest tray and disposed above said original conveying and holding section for receiving each original conveyed thereto by said second conveying means, said tray having a flat undersurface thereon; and iii. mounting means for pivoting said receiving tray from said inclined position to a rest position with its flat undersurface on the flat upper surface of said original conveying and holding section; the original conveying and holding section and the original ejecting section being connected to each other and pivotable as a unit about said pivot means on said stand-by section so as to permit access to the copying position of the duplicating machine without removing the device therefrom.
Claim 3
Dependent Claim
118 words
An automatic original feed device as set forth in claim 1 wherein said original rest tray is disposed on said stand-by section in an inclined position and supports a stack of originals piled thereon with the leading end edges of upper originals extending further forwardly in the feed direction than the leading end edges of lower originals, and said separating means comprises a pair of rollers arranged one above the other at the exit of said rest tray, the upper roller being normally driven to rotate while the other roller is adapted not to rotate, said two rollers being spaced apart from each other a distance such that only a single original can pass therebetween at a time.
Claim 4
Dependent Claim
76 words
An automatic original feed device as set forth in claim 1 wherein said first conveying means comprises an endless belt having an upper tensioned run and a lower loosened run and arranged such that its loosened run is brought into engagement with the copying position of the duplicating machine, and said holding means comprises a plurality of pressing rollers disposed on the back side of the loosened run of the endless belt in pressing engagement therewith.
Claim 5
Dependent Claim
52 words
An automatic original feed device as set forth in claim 1 wherein said original ejecting section further comprises means for altering the path of movement of originals from the original rest tray to the original receiving tray such that the direction of movement of the originals is changed through more than 90*.
Claim 6
Dependent Claim
63 words
An automatic original feed device as set forth in claim 1 wherein said original ejecting section further comprises a receiving tray holding means for holding said receiving tray on said original conveying and holding section by magnetic attraction when said original receiving tray is pivoted from said inclined position with respect to said original conveying and holding section to a rest position thereon.
Claim 7
Dependent Claim
29 words
An automatic original feed device as set forth in claim 1 wherein said pivot means comprises a shaft to which said original conveying and holding section is pivotally connected.
