Abstract

Abstract An automatic document handler having a tray for supporting documents to be copied for supplying to and removing documents from the platen (12) of a copying machine includes a register against which the document trailing edge is abutted through reversal of a platen transport. The platen transport comprises an endless belt conveyor (40) supported above the platen (12), with normal sag in the belt or its catenary allowing the belt to contact the platen to provide the driving force for moving a document across the platen. An anti-skewing pair of roller devices (77,81) are provided to force the belt (40) down against a document and platen (12) to provide a greater force between the belt and the platen to assure positive driving of the document over the register for return of the document to the tray (14). <IMAGE>

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 141 words
Document handling apparatus for moving documents into copying position on the platen of a reproduction machine having a flexible document transport belt disposed over the platen and arranged so the operating run of the belt is spaced slightly above the plane of the platen, a register edge adjacent the platen and means for driving the belt in one direction for transporting a document onto the platen and in the reverse direction to register the document for copying thereof and continued reverse direction to transport the document over the register edge and off the platen, and a plurality of rollers positioned above the operating run of the transport belt and arranged for contact with the run overlying a document and platen during the movement of the belt in the reverse direction for providing a frictional force between the belt and the document.
Claim 2
Dependent Claim 141 words
Document handling apparatus for moving documents into copying position on the platen of a reproduction machine having a flexible document transport belt disposed over the platen and arranged so the operating run of the belt is spaced slightly above the plane of the platen, a register edge adjacent the platen and means for driving the belt in one direction for transporting a document onto the platen and in the reverse direction to register the document for copying thereof and continued reverse direction to transport the document over the register edge and off the platen, and a plurality of rollers positioned above the operating run of the transport belt and arranged for contact with the run overlying a document and platen during the movement of the belt in the reverse direction for providing a frictional force between the belt and the document.
Claim 3
Dependent Claim 27 words
Document handling apparatus according to Claim 1 wherein two of the rollers are in alignment with the direction of movement of the operating run of the belt.
Claim 4
Dependent Claim 20 words
Document handling apparatus according to Claim 1 including means for intermittently moving said rollers into contact with the operating run.
Claim 5
Dependent Claim 33 words
Document handling apparatus according to Claim 3 wherein said means for moving said rollers into contact with the belt is actuable only when a document is to be transported over the register edge.
Claim 6
Dependent Claim 19 words
Document handling apparatus constructed, arranged and adapted to operate substantially as hereinbefore described with reference to the accompanying drawings.
Claim 7
Dependent Claim 19 words
Document handling apparatus constructed, arranged and adapted to operate substantially as hereinbefore described with reference to the accompanying drawings.
