Abstract

PURPOSE: To store different discrimination data on many cards by branching light, passed through a light source side optical filter equipped in a card, to a plurality of optical paths and by performing photoelectric conversion after passing branched light beams through photodetection side optical filters having prescribed passing- band characteristics.
CONSTITUTION: In hole 12 formed in optical card 11, optical filter 13 of prescribed combination is equipped. Light 16 from light source 15, after passing through filter 13, is branched into four beams in this case through optical fibers 17A, 17B, 17C and 17D and respective beams are led to photoelectric converting elements 19A, 19B, 19C, and 19D via photodetection-side optical filters 18A, 18B, 18C, and 18D respectively. When light beam 16 is a white light beam, five kinds of data can be obtained through one hole made in card 11. Thus, different discrimination data can be stored on many cards.
