Title: Dichroic copying machine
Inventor: KAJIWARA NORIO
IPC: G03G15/01
Filed: 1983-03-07
Abstract: PURPOSE:To obtain picture quality suitable for the purpose of use and facilitate unit arrangement by obtaining two split pieces of luminous flux through a luminous flux splitting means, and using transmitted light for black image formation and reflected light for the 2nd color image formation. CONSTITUTION:An original on contact glass 1 is lighted up by an exposure lamp 2 and its reflected luminous flux is split by a half-mirror 7 into the reflected light and transmitted light. The reflected luminous flux which can not evade a decrease in resolving power forms an image in a photosensitive body 11 for red, and the transmitted light decreasing no resolving power forms an image on a photosensitive body 12 for black. Consequently, the resolving power of a black picture as an information picture does not decrease. On the other hand, a red picture decreases in resolving power, but the red picture is used principally for marking, so there is no problem even when the resolving power is not high. Further, the arrangement of respective units, specially, a developing unit is facilitated because of the projection position of image-forming light to the photosensitive bodies 11 and 12.
