Abstract
PURPOSE: To execure part of the mark processing of a data processor apparently by hardware, by installing a mark recognition unit between a raster scan type reader and the data processor.
CONSTITUTION: In the sub-scan direction of the raster scan type reader, reference marks 102 of long segment and scan position assignment marks 103 of a segment in parallel to those marks 102 are printed on mark sheet 104 in a color the raster scan type reader can sense, in addition to mark items 104 printed in parallel to marks 102 in a color this reader can not sense. From a raster signal obtained by scanning on this sheet 101 by the raster scanning reader, a raster signal component as to where marks 102 reside only is extracted by mark-recognition pre-processor 202 provided, which decides on the existence of mark 103 on each scanning line of the raster signal and on the existence of a mark entered in mark item 104 to generate information consisting of bits of "1" or "0". Then, the information generated by this processor 202 is inputted to the data processor.
