PURPOSE:To get rid of overlapping of write to a memory, which is caused by overlapping of a read area by image sensors, by delaying the time of store to the memory so as to correspond to size of an area which is read repeatedly by the image sensors. CONSTITUTION:An original 1 is read by two image sensors CCD1, CCD2. The image sensore CCD1, CCD2 are provided so as to have a prescribed overlapped read area. Before the original 1 is read, a mark 5 which is provided in advance out of a scanning area of the original 1 is read, and size of overlapping of these two image sensors CCD1, CCD2 is decided by a signal of said mark 5. Also, the memory corresponding to the image sensor CCD2 delays the timing of start of store in accordance wth size of overlapping of the read area by the two image sensors CCD1, CCD2. |
