Abstract
A copy board for a reproducing camera in which the illumination of an original to be copied is maintained constant, independent of the size of the original. The copy board includes first and second sets of masking members with the two members of each set being reciprocatable in opposite directions from one another and with the directions of reciprocation of the two sets being perpendicular to one another. The sides of the mask members disposed towards a light source are made reflective, while the opposite sides are made light absorbing. An original guide member is provided on the surface of the copy board, with the original guide member being movable in synchronization with the movement of the mask members.
