Abstract

Abstract Documents to be copied are positioned on the platen of a copying machine and then removed following copying by a sliding cover which is first moved into position above the platen and then down into contact with the document on the platen and then moved in a reverse direction to frictionally carry the document which has been copied and return it to a storage tray. Upon repeating the above steps, a stack of precollated documents may be easily copied and restacked in collated order for producing sets thereof under the control of a machine operator.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 179 words
In an electrostatic copying machine in which precollated documents are to be copied and then removed from a platen and stacked, an improved document handling device comprising: a frame; a cover member positiOned on said frame for holding a stack of documents to be copied, said cover member being adapted for sliding movement on said frame across the platen, said frame being formed with parallel slots contiguous to the platen, said slots extending in a linear path and then bifurcating with a first path which curves upwardly above the platen then linearly across the platen and then downwardly towards the platen and with a second path extending linearly and joining to the first path, said cover member having a plurality of pin members received in said slots whereby upon sliding said cover member in a first direction it moves upwardly above the platen and then downwardly towards the platen contacting a document thereon and upon moving in a reverse direction removes the document from the platen after copying thereof and slides it into a receiving tray on the frame.
Claim 2
Dependent Claim 179 words
In an electrostatic copying machine in which precollated documents are to be copied and then removed from a platen and stacked, an improved document handling device comprising: a frame; a cover member positiOned on said frame for holding a stack of documents to be copied, said cover member being adapted for sliding movement on said frame across the platen, said frame being formed with parallel slots contiguous to the platen, said slots extending in a linear path and then bifurcating with a first path which curves upwardly above the platen then linearly across the platen and then downwardly towards the platen and with a second path extending linearly and joining to the first path, said cover member having a plurality of pin members received in said slots whereby upon sliding said cover member in a first direction it moves upwardly above the platen and then downwardly towards the platen contacting a document thereon and upon moving in a reverse direction removes the document from the platen after copying thereof and slides it into a receiving tray on the frame.
Claim 3
Dependent Claim 35 words
A device according to claim 1 including a pivotable ramp member is positioned adjacent to the platen to cause a cover member to follow said first path upon sliding in a direction towards the platen.
Claim 4
Independent Claim 127 words
A method of copying documents on a copying machine wherein precollated documents are copied from a stack and then removed from the platen and restacked in collated fashion comprising the steps of positioning a stack of documents on a sliding cover adjacent to the platen, removing a first document to be copied and placing it on the platen, sliding the cover over the platen such that the bottom of the cover comes into contact with the document, copying the document, sliding the cover in a reverse direction carrying the document which has been copied with it and depositing it to a stacking area, placing the next document on the top of the platen area and repeating the before mentioned steps until all the documents have been copied.
Claim 5
Independent Claim 127 words
