PURPOSE:To make arrangement that the copying can be performed only when specified marks on both originals and copying paper are read, by installing two readers which read the specified marks on originals and copying paper. CONSTITUTION:The 1st mark reader 11 is to read a specified mark put on an original (0) and installed to a position near the 1st scanning mirror 4 where the reader 11 does not obstruct the transmission of the light image of the original (0). The 2nd mark reader 12 is installed to a position, from which the reader 12 can read a specified mark put on the copying paper (P) in a paper feeding cassette 8. When the specified mark is put on an original, the copying can be performed only when the copying paper with the specified mark is read, and no copying is performed when other copying paper is fed. |
