Abstract
PURPOSE: To achieve higher accuracy of detection and eliminate the need for any mechanical adjustment by disposing a member of lower light reflectance to the end part on the original read start end side of the contact glass plate for original placement.
CONSTITUTION: A black film 18 is interposed in the form of being placed along the read start end of an original IP between the fixing frame 19 for holding the contact glass plate 17 placed on the top wall 20 of the outer case of the copying machine and the contact glass plate 17. Hence, optical reading is started from the black color film 18 by the photoelectric transducer for original reading and when the scanning reaches the original leading end, the read signal erases and therefore the original end may be detected by detecting this.
