Abstract

PURPOSE: To simplify driving circuits for a reader and photodetectors by reading and deciding one piece of color information by one photodetector and the other by two photodetectors when deciding information, read by photodetectors,as two pieces of color information.
CONSTITUTION: Duplicator 100 constists of read part 101 that reads information entered in an original and write part 102 that writes the read information on a recording medium and over read part 101, original table 103 where the original is mounted, light source 104, reflex mirror 105, etc., are provided, so that the original surface can be scanned by the scanning mechanism with guide rail 113, etc., fitted to base 112. A light image obtained by scanning the original surface in this way is formed on lens 108 by way of the 2nd plane mirror 107 and then color-separated by beam splitter 109. One piece of color information obtained through the color separation is decided and read by one photodetector 110-2 and the other piece of color information by two photodetectors 110-1 and 110-3 before being sent to the write head of write part 102 while it is made easy to drive photodetectors 110-1W110-3.
