Claim 1
Independent Claim 94 words
An image reading apparatus, comprising: an original table provided with an image focusing plane for focusing thereon an image projected from a transparent original; an original table cover means for shielding the original table, said original table cover means having an image projection window and a lid member having one end being engaged with said original table cover and being adapted to cover or expose the image projection window, said lid member having a reflector on the inner surface thereof for reflecting the projected image toward the image focusing plane on the original table.
Claim 2
Dependent Claim 94 words
An image reading apparatus, comprising: an original table provided with an image focusing plane for focusing thereon an image projected from a transparent original; an original table cover means for shielding the original table, said original table cover means having an image projection window and a lid member having one end being engaged with said original table cover and being adapted to cover or expose the image projection window, said lid member having a reflector on the inner surface thereof for reflecting the projected image toward the image focusing plane on the original table.
Claim 3
Dependent Claim 164 words
An image reading apparatus, comprising an original table provided with an image focusing plane for focusing thereon an image projected from a transparent original; an original table cover means for shielding the original table, said original table cover means having a light receiving window provided in said original table cover at a position corresponding to said image focusing plane; a light emitting window provided in said original table cover at a position through which the projected light from said transparent original passes; a pair of lid members each having respective ends movably attached to said light receiving window and said light emitting window at the respective side edge portions thereof most distant from each other; a pair of reflectors provided on the respective inner surfaces of said pair of lid members; and pairs of support members for supporting said pair of lid members with respect to said original table cover at angles of about 45 degrees between said respective reflectors and said original table.
Claim 4
Dependent Claim 164 words
