ABSTRACT:
A first member and a second member are coupled so as to form a flat card path therebetween. The card path is open at one end of each of the first and second members. A plurality of guide holes are formed in the first member so as to open to the card path. The guide holes are substantially perpendicular to the card path. A plurality of light-emitting elements are respectively mounted in the guide holes such that a light-emitting direction of each light-emitting element crosses the card path. A plurality of photodetector chambers are formed in the second member such that each photodetector has an optical axis aligned with that of each light-emitting element. A plurality of light-receiving elements are housed in the photodetector chambers so as to receive only light beams having a predetermined wavelength through respective filters. An information card having pattern data formed by a fluophor thereon is inserted along the card path, thereby allowing reading of the pattern data by the light-receiving elements.
