Abstract
Abstract An arrangement is disclosed for combining the capability for bound document copying with a document handling apparatus in a reproduction machine. To this end, an arrangement is devised wherein the document handling apparatus is contained within a frame which contains a light-tight cover for bound documents having three-dimensional shape. The arrangement includes a pivoting connection between the document handling apparatus and the frame relative to the platen of the reproduction machine and between each other so as to permit access to the platen for manual document placement and bound document copying.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
148 words
In an electrostatographic reproduction machine having a support frame, document handling apparatus for advancing document sheets from a stack to an exposure platen, and an electrostatographic processor for processing copy sheets of the document sheets when exposed, the improvement comprising: a housing for containing the document handling apparatus, pivotal support means on the machine frame and connected to said housing for permitting the pivotal movement of the document handling apparatus toward and away from the exposure platen, and a bound document cover assembly detachably retained by said housing, said cover assembly being connected to said pivotal support means and movable as a unit with said housing to expose the exposure platen for manual use, said housing being pivotally related to said cover assembly whereby the latter may be maintained on said platen while said housing is in a pivoted raised position, so as to permit bound document copying.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
47 words
The improvement in claim 1 wherein said cover assembly is in the form of a frame having side and end members and between which the document handling apparatus is adapted to be retained when the housing and cover assembly are positioned as a unit on the platen.
Claim 4
Dependent Claim
32 words
The improvement in claim 1 wherein said cover assembly includes a movable, light-tight apparatus adapted to be positioned above the platen in light-tight arrangement for surrounding a three-dimensional object on the platen.
Claim 5
Dependent Claim
25 words
The improvement in claim 2 including means for inhibiting the operation of the processor when said cover assembly has been pivoted away from the platen.
Claim 6
Dependent Claim
25 words
The improvement in claim 3 wherein said movable apparatus includes a depending curtain connected to a fan-folding array of panels being slidable across the platen.
Claim 7
Dependent Claim
25 words
The improvement in claim 5 wherein said fan-folding array is positionable in spaced relation to the exposure platen so as to accommodate three-dimensional objects therebetween.
