Abstract
PURPOSE: To identify whether the data is the writing frame information or the stain or others, by reading the information within the mark writing frame through the optical character reader to then send the information to the picture memory after the photoelectric conversion and the quantization and then carrying out an addition process via the address register and the ROM.
CONSTITUTION: The sensor 4 amplifies 5 the output via the photodetector of the optical character reader OCR, and then changes the amplified output into the quantum code of "1" or "0" through the quantum coding part 6. And this signal is written into the picture memory 8 via the memory direct writing part 7 not via the CPU9. The data written into the memory 8 are written into the address register 11 by e.g. 8 bits to be turned directly into the address of the ROM12. As a result, the information within the mark writing frame is read out. And an identification is possible from the arithmetic value obtained by the successive addition 13 of "1" through the ROM12 and whether the data of the mark writing frame is due to the written mark or the stain and others.
