Claim 1
Independent Claim
211 words
Electrophotographic copying apparatus for exposing a photosensitive copy sheet to an image of an original, comprising: means defining an exposing station for a photosensitive copy sheet; means for projecting a light image of an original onto a photosensitive copy sheet positioned at said exposing station; and means for preventing the formation of undesirable images on marginal portions of a photosensitive copy sheet positioned at said exposing station simultaneously with the formation of a light image of an original onto a photosensitive copy sheet, said last mentioned means comprising erasing light source means generating light beams along a path for illuminating marginal portions of a photosensitive copy sheet positioned at said exposing station, adjustable intercepting plate means interposed between the erasing light source means and a photosensitive copy sheet positioned at said exposing station for directing the light emanating from said erasing light source means to selected marginal portions of a photosensitive copy sheet at said exposing station and for preventing said light beams from being projected on any other image forming portion of a photosensitive copy sheet positioned at said exposing station other than the marginal portions thereof, and support means for supporting said intercepting plate means in the path of the light beams generated by said erasing light source means.

Electrophotographic copying apparatus for exposing a photosensitive copy sheet to an image of an original, comprising: means defining an exposing station for a photosensitive copy sheet; means for projecting a light image of an original onto a photosensitive copy sheet positioned at said exposing station; and means for preventing the formation of undesirable images on marginal portions of a photosensitive copy sheet positioned at said exposing station simultaneously with the formation of a light image of an original onto a photosensitive copy sheet, said last mentioned means comprising erasing light source means generating light beams along a path for illuminating marginal portions of a photosensitive copy sheet positioned at said exposing station, adjustable intercepting plate means interposed between the erasing light source means and a photosensitive copy sheet positioned at said exposing station for directing the light emanating from said erasing light source means to selected marginal portions of a photosensitive copy sheet at said exposing station and for preventing said light beams from being projected on any other image forming portion of a photosensitive copy sheet positioned at said exposing station other than the marginal portions thereof, and support means for supporting said intercepting plate means in the path of the light beams generated by said erasing light source means.
Claim 3
Dependent Claim
82 words
Electrophotographic copying apparatus as in claim 1 including a conveyor belt means made of transparent material, said conveyor belt means conveying a photosensitive copy sheet to said exposing station, and a member positioned adjacent said conveyor belt means at a slide opposite a photosensitive copy sheet positioned at the exposing station, said member having a surface facing the conveyor belt means and provided with a reflecting surface having thereon a plurality of frames corresponding to predetermined sizes of a photosensitive copy sheet.
Claim 4
Dependent Claim
48 words
Apparatus as in claim 1 wherein said copying apparatus is contained with an enclosure and including a viewing window in said enclosure allowing viewing from outside said enclosure of the exposing station and an image of the original on a photosensitive copy sheet formed at said exposing station.
Claim 5
Dependent Claim
102 words
Apparatus as in claim 3 including a conveyor belt means for positioning a photosensitive copy sheet at said exposing station, said conveyor belt means being made of transparent material, and a member positioned adjacent said coNveyor belt means on a side opposite a photosensitive copy sheet positioned at the exposing station, said member having a reflecting surface facing the conveyor belt means, said reflecting surface having thereon a plurality of frames, each frame corresponding in size to a defined size of a photosensitive copy sheet, said reflecting surface and the frames thereon being visible from outside said enclosure through the viewing window.
Claim 6
Dependent Claim
24 words
Electrophotographic copying apparatus as in claim 1 including means defining a viewing window allowing viewing of said exposing station from outside the copying apparatus.
