Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
158 words
In a reproducing apparatus comprising: means for discharging an original from an exposure station after exposure; said exposure station comprising: an exposure platen; fixed stop means having a stop surface for engaging an edge of said original for determining the position of said original on said exposure platen; and means for projecting an image of said original at said platen onto a photosensitive body; said discharging means including means for feeding said original in a desired direction off said platen and over said fixed stop means; the improvement, wherein, said apparatus further includes: means for flowing air against said edge of said original and across said platen in a direction opposed to said desired direction in which said original is fed off said platen, said means for flowing air forming an air layer between said exposure platen and said original for lifting said edge of said original so that it can be discharged over said fixed stop means.
