Abstract

PURPOSE: To increase the character detection speed and accuracy, by detecting the space on paper and discriminating detected character area.
CONSTITUTION: When the letter 11 passes through the position of the scanning unit 22, the letter 11 is scanned. The pattern signal output in binary of the scanning unit 22 is fed to one input of the AND circuit 23. The control signal to pickup the pattern signal for the specific part 29 excluding the areas 17, 18 including the part to be noise in the detection of the space 14 is fed to another input of the AND circuit 23 with the pattern pickup control signal generating circuit 26. The space detection circuit 27 detects the space 14 from the pickup pattern signal from the AND circuit 23, the detection signal and its detection information are produced, and they are fed to the discrimination circuit 28. The discrimination circuit 28 discriminates the space f is the desired space 14, detects the right side form f is the character area being objective and outputs it.
