Abstract
Abstract The housing of an electrostatic copying machine has an opening in the top thereof located over the means in the housing defining an exposure station. An open frame is disposed in such opening. A glass platen and a cover are each hingedly secured to this frame for individual swinging movement to and away from their normal positions wherein such members are coplanar with the frame. The frame is mounted for pivotal movement through 180* back and forth between a copying position wherein the cover may be swung away from the frame thereby permitting the material to be copied to be placed face down on the glass platen and a loading position wherein the glass platen may be swung away from the frame thereby permitting the material to be copied to be placed face up on the cover.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
268 words
In an electrostatic copying machine of the type having a housing including means defining an exposure station and having a first opening in the top of said housing over said means, the improvement comprising: a. a frame disposed in said opening, the former being generally planar and shaped complementarily with the latter said frame defining a second opening extending therethrough from one face of the frame to the other face thereof and having an area at least as large as the area of the material to be copied; b. a transparent platen substantially coextensive with said second opening and hingedly secured to the latter for swinging movement to and away from a normal position wherein it is parallel with the plane of said frame adjacent said one face thereof; c. a cover substantially coextensive with said platen and hingedly secured to said frame for swinging movement to and away from a normal position wherein it is parallel with the plane of said frame adjacent said other face thereof; d. mounting means supporting said frame in said opening for pivoting movement through 180* back and forth between: 1. a copying position wherein said frame is horizontally disposed with said cover being over said platen thereby permitting copying of material by swinging the cover away from the platen and placing the material face down on the latter; and 2. a loading position wherein said frame is horizontally disposed with said platen being over said cover thereby permitting mounting of material to be copied by swinging the platen away from the cover and placing the material face up on the latter.

Claim 5
Dependent Claim
39 words
a copying position wherein said frame is horizontally disposed with said cover being over said platen thereby permitting copying of material by swinging the cover away from the platen and placing the material face down on the latter; and
Claim 6
Dependent Claim
39 words
a copying position wherein said frame is horizontally disposed with said cover being over said platen thereby permitting copying of material by swinging the cover away from the platen and placing the material face down on the latter; and
Claim 7
Dependent Claim
41 words
a loading position wherein said frame is horizontally disposed with said platen being over said cover thereby permitting mounting of material to be copied by swinging the platen away from the cover and placing the material face up on the latter.
Claim 8
Dependent Claim
41 words
a loading position wherein said frame is horizontally disposed with said platen being over said cover thereby permitting mounting of material to be copied by swinging the platen away from the cover and placing the material face up on the latter.
Claim 9
Dependent Claim
29 words
The improvement according to claim 1 further defined by latch means engaging said housing and said frame for alternately releasably securing the latter in its copying and loading positions.
Claim 10
Dependent Claim
59 words
The improvement according to claim 1 further defined by: a. counterbalancing means connected with said frame and said cover for releasably holding the latter in any of its positions relative to the former; and b. other counterbalancing means connected with said frame and said platen for releasably holding the latter in any of its positions relative to the former.
Claim 11
Dependent Claim
152 words
The improvement according to claim 1 further defined by: a. first latch means engaged with said housing and said frame for alternately, releasably securing the latter in said copying and loading positions, release of said first latch meaNs permitting said pivotal movement of the frame; b. second latch means engaging said frame and said platen for releasably securing the latter in its parallel position with the former; c. third latch means engaging said frame and said cover for releasably securing the latter in its parallel position with the former; d. first interlock means engaged with said first and second latch means for preventing release of the former upon release of the latter to swing said platen away from said frame; and e. second interlock means engaged with said first and third latch means for preventing release of the former upon release of the latter to swing said cover away from said frame.
