PURPOSE:To compensate effectively the blur in scanning, by allowing an optical pattern reading means and a coordinate detecting means to cooperate with each other to store output information in accordance with the coordinate position of the pattern reading means. CONSTITUTION:When the x coordinate position detected at a sample time T is not changed from the X coordinate position at a time T-1, data transmitted from a read sensor 9 is not written in a memory 17. When the X coordinate position at the time T is changed from that at the time T-1, X coordinates at the time T are transmitted to a memory address indicating part 16. On a basis of the change of x coordinates, the shift operation is performed in a shift circuit 15 in accordance with a quantity proportional to the difference between Y coordinates discriminated by X-Y coordinate detecting circuit 13 and y coordinates at the hand scanning start time, and this data is entered in the address indicated by the memory address indicating part 16. |
