Abstract

PURPOSE: To avoid eyesore when the characters on the recording medium are read with eyes, by taking the recording substance for the code pattern described together with the mother pattern of characters on the recording medium as fluorescent substance colorless which is excited with infrared rays.
CONSTITUTION: When the mother pattern and code pattern of characters are described parallelly on the recording medium 5, as the recording sybstance of code pattern fluorescent substance colorless or background color which is excited with infrared rays in used. This recording medium 5 is passed through the part between the paper feed stand 7 and the slit plate 6 and fed in the part clipped with the photo detection plate 6 and fed in the part clipped with the photo detection diode array 3 and the infrared ray emission diode array 4. Thus, colorless code pattern is excited with infrared rays to emit fluorescent light which is received with the photo detection diode array 3 for photo electric conversion.
