Image reading apparatus

Claim 2

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

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

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 5

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 engaged with said original table cover and 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; and first support members, each having one end being engaged with said original table cover, the other end being movably attached to said lid member, said first support members supporting said lid member at an angle of about 45 degrees between said reflector and said image focusing plane on the original table.

Claim 6

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 engaged with said original table cover and 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; and first support members, each having one end being engaged with said original table cover, the other end being movably attached to said lid member, said first support members supporting said lid member at an angle of about 45 degrees between said reflector and said image focusing plane on the original table.

Claim 7

The apparatus of claim 3, wherein said first support members are a pair of supports, each having one end being engaged with said original table cover on inner edges of both sides of said image projection window, the other end being movably attached to the lid member on both sides of said reflector.

Claim 8

The apparatus of claim 4, wherein said lid member has grooves on both sides of said reflector for receiving said first support members.

Claim 9

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; and p1 a rectangular protective member one end of which is movably attached to the unengaged end of said lid member, the other end being supported by second support members at a position parallel to said original table cover.

Claim 10

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; and p1 a rectangular protective member one end of which is movably attached to the unengaged end of said lid member, the other end being supported by second support members at a position parallel to said original table cover.

Claim 11

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; a reflector means provided on the original table cover; and a projector means for projecting an image toward the reflector means.

Claim 12

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; a reflector means provided on the original table cover; and a projector means for projecting an image toward the reflector means.
