Abstract
Abstract The image reproduction apparatus of the present invention can make a copy of images written or drawn on a board as well as a copy of images of an original provided on an original table. The image reproduction apparatus comprises a board portion and a copying portion. The optical information of images written or drawn on a board is supplied to the copying section through an optical system. The copying section moves between a position where the image reproduction is performed by the above optical information and a position where an ordinary copying of the original is performed. Thus, according to the present invention, the copying section moves between said two positions.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
128 words
In the image reproduction apparatus including a display section where a display member provided with a display surface on and from which images can be written and erased is arranged movable, and a copying section detachable from the display section and capable of selectively copying images on the display surface and those on originals on a table on which the originals are mounted, said image reproduction apparatus characterized in that said copying section has a means for moving between a first position where said copying section is engaged with the display section and a second position where it is released from the display section, and that the image written on the display surface is copied at the first position while the original is copied at the second position.
Claim 2
Dependent Claim
128 words
In the image reproduction apparatus including a display section where a display member provided with a display surface on and from which images can be written and erased is arranged movable, and a copying section detachable from the display section and capable of selectively copying images on the display surface and those on originals on a table on which the originals are mounted, said image reproduction apparatus characterized in that said copying section has a means for moving between a first position where said copying section is engaged with the display section and a second position where it is released from the display section, and that the image written on the display surface is copied at the first position while the original is copied at the second position.
Claim 3
Dependent Claim
175 words
In the image reproduction apparatus including a display section where a display member provided with a display surface on and from which images can be written and erased is arranged movable, and a copying section detachable from the display section and capable of selectively copying images on the display surface and those on originals on a table on which the originals are mounted, said image forming device characterized in that said display section has a drive means for causing the display member to be moved, a light source for exposing the display surface, and a first optical system for introducing light reflected from the display surface to the copying section, and that said copying section is movable between the first position where said copying section is engaged with the display section and the second position where it is released from the display section and has a second optical system introducing light, which is formed when the light of the light source located in the copying section is reflected by the original, to an image carrier.
Claim 4
Dependent Claim
175 words
In the image reproduction apparatus including a display section where a display member provided with a display surface on and from which images can be written and erased is arranged movable, and a copying section detachable from the display section and capable of selectively copying images on the display surface and those on originals on a table on which the originals are mounted, said image forming device characterized in that said display section has a drive means for causing the display member to be moved, a light source for exposing the display surface, and a first optical system for introducing light reflected from the display surface to the copying section, and that said copying section is movable between the first position where said copying section is engaged with the display section and the second position where it is released from the display section and has a second optical system introducing light, which is formed when the light of the light source located in the copying section is reflected by the original, to an image carrier.
Claim 5
Dependent Claim
24 words
A image reproduction apparatus according to claim 1 wherein said display member is a belt-like sheet member provided with a plurality of display faces.
Claim 6
Dependent Claim
24 words
An image reproduction apparatus according to claim 3 wherein said display member is provided with indication means each indicating each of the display faces.
Claim 7
Dependent Claim
14 words
An image reproduction apparatus according to claim 4 wherein said indication means are marks.
Claim 8
Dependent Claim
37 words
An image reproduction apparatus according to claim 1 wherein the moving direction of said display surface which is under display is the same as the scanning direction performed at the original copying time in the copying section.
Claim 9
Dependent Claim
40 words
An image reproduction apparatus according to claim 1 wherein said copying section is provided with an exposure opening through which the light reflected from the display surface is introduced, and a shutter means for opening and closing the exposure opening.
Claim 10
Dependent Claim
27 words
An image reproduction apparatus according to claim 1 wherein a first detector means is adapted to detect that said copying section is located at the first position.
Claim 11
Dependent Claim
27 words
An image reproduction apparatus according to claim 1 wherein a second detector means is adapted to detect that said copying section is located at the second position.
Claim 12
Dependent Claim
30 words
An image reproduction apparatus according to claim 8 wherein said display and copying sections can start their copying operation responsive to an output signal applied from the first detector means.
Claim 13
Dependent Claim
28 words
An image reproduction apparatus according to claim 9 wherein said copying section can start its copying operation responsive to an output signal applied from the second detector means.
Claim 14
Dependent Claim
40 words

Claim 15
Dependent Claim
73 words
An image reproduction apparatus according to claim 1 wherein said copying section has a support for enabling said copying section to move between the first and the second position, and wherein said copying section is supported by a display section bearing member in a case where said copying section is at the first position, while it is supported at least by its support in a case where it is at the second position.
Claim 16
Dependent Claim
41 words
An image reproduction apparatus according to claim 2 wherein said second optical system moves to a position of its not interfering the light passage which is formed by the first optical system, when said copying section is at the first position.
Claim 17
Dependent Claim
36 words
An image reproduction apparatus according to claim 2 wherein a shielding means is present between said display section and said copying section to shield light from outside, when said copying section is at the first position.
