Abstract
Abstract A copy board apparatus for copying information on a web-like writing board supported by rollers with an electrophotographic copier disposed adjacent one longitudinal end of the writing board. The apparatus has a first optical system for optically connecting the writing board and a photosensitive member of the copier, a second optical system for optically connecting an original on the copier and the photosensitive member, and change-over circuitry which permits switching between the two optical systems.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
131 words
A copy board apparatus for copying information recorded on a writing board, said apparatus comprising: a board section including a web forming said writing board, rollers for supporting said web such that said web extends in a plane, and driving means for driving at least one of said rollers thereby to move said web; a copier section including an electrophotographic copier having an original carrier and a photosensitive member, said copier being disposed adjacent one longitudinal end of said writing board; a first optical system for forming, on said photosensitive member, an image of information recorded on said web; a second optical system for forming, on said photosensitive member, an image of an original on said original carrier; and change-over means for effecting switching between said first and second optical systems.
Claim 2
Dependent Claim
131 words
A copy board apparatus for copying information recorded on a writing board, said apparatus comprising: a board section including a web forming said writing board, rollers for supporting said web such that said web extends in a plane, and driving means for driving at least one of said rollers thereby to move said web; a copier section including an electrophotographic copier having an original carrier and a photosensitive member, said copier being disposed adjacent one longitudinal end of said writing board; a first optical system for forming, on said photosensitive member, an image of information recorded on said web; a second optical system for forming, on said photosensitive member, an image of an original on said original carrier; and change-over means for effecting switching between said first and second optical systems.
Claim 3
Dependent Claim
30 words
A copy board apparatus according to claim 1, wherein said first optical system is disposed on the side of said writing board opposite the side where information is recorded thereon.
Claim 4
Dependent Claim
59 words
A copy board apparatus according to claim 1, wherein said first optical system is disposed on the side of said writing board opposite the side where information is recorded thereon and includes means for projecting the image to a region above said copier section, said projecting means being adapted to be received in a housing of said copy board.
Claim 5
Dependent Claim
138 words
A copy board apparatus for copying picture information recorded on a writing board, said apparatus comprising: a board section including a web forming said writing board, rollers for supporting said web such that said web is movable in a horizontal direction, and driving means for driving at least one of said rollers thereby to move said web; a copier section including an electrophotographic copier having an original carrier and a photosensitive member which is movable perpendicularly to the direction of movement of said web; a first optical system for forming, on said photosensitive member, an image of information recorded on said web; a second optical system for forming, on said photosensitive member, an image of an original on said original carrier of said copier; and a change-over means for effecting switching between said first and second optical systems.
Claim 6
Dependent Claim
138 words
A copy board apparatus for copying picture information recorded on a writing board, said apparatus comprising: a board section including a web forming said writing board, rollers for supporting said web such that said web is movable in a horizontal direction, and driving means for driving at least one of said rollers thereby to move said web; a copier section including an electrophotographic copier having an original carrier and a photosensitive member which is movable perpendicularly to the direction of movement of said web; a first optical system for forming, on said photosensitive member, an image of information recorded on said web; a second optical system for forming, on said photosensitive member, an image of an original on said original carrier of said copier; and a change-over means for effecting switching between said first and second optical systems.
Claim 7
Dependent Claim
30 words
A copy board apparatus according to claim 4, wherein said first optical system is disposed on the side of said writing board opposite the side where information is recorded thereon.
Claim 8
Dependent Claim
59 words
A copy board apparatus according to claim 4, wherein said first optical system includes a mirror which extends in a direction perpendicular to the direction of movement of said web, and an image forming lens disposed between said copier and said mirror, said image forming lens being adapted to reflect the light from said mirror towards said photosensitive member.
Claim 9
Dependent Claim
45 words
A copy board apparatus according to claim 6, wherein said mirror and said image forming lens of said first optical system are supported as a unit, and are adapted to be moved between a position above said copier and a position within said board section.
Claim 10
Dependent Claim
22 words
A copy board apparatus according to claim 4, wherein said original carrier is a movable carriage for conveying an original disposed thereon.
