ABSTRACT:
In order to check if information stored on a card is authentic, the embossed character and figure information is compared with the information on the card. The rays radiated from the light emitting elements arranged in a line pass through a slit whose width is substantially equal to the thickness of embossed portions. Then, the rays are reflected on a card surface and received at an optical sensor consisting of LED elements arranged in a line as the card is in transit. The optical sensor is oriented in a manner to keep the same angle of reflection as the angle of incidence with respect to a normal. The light emitting elements are oriented to form another angle of incidence. These elements are used for reading the printed characters. To read a color pattern, a sensor having a photo detection sensitivity toward a normal of the card serves to receive the scattered rays reflected on the card, which rays are obliquely radiated to the card.
