Abstract

PURPOSE: To enable a part of copy images to be erased without using dummy blank paper by providing an erase position indicator which is capable of assigning the sub- scanning direction position of scan face and outputting said assignment position in the form of an electric signal.
CONSTITUTION: An erase position indicator 10 which assigns the sub-scanning direction position of an orignal scan face 2 consists of a movable indicating member 11 and a potentiomometer 12 and the output of the potentiometer 2 is digitized by an A/D converter 17 and is sent to a latch circuit 18. On the other hand, the actual scanning line number is counted with a counter 19 and is compared with the output of the latch circuit 18 in a comparator 20. When it exceeds the intended line number, the input of a processing transmission circuit 4 is changed over from the sensor side to the blank generator 25 side. As a result, when the actual scanning line comes to the erase indication position, the subsequent copying is processed as blank, thus a part of the copy may be made to blank as desired.
