ABSTRACT:
An optical card scanning apparatus includes a mechanism for forwardly conveying an optical card inserted into a housing through an insertion port toward a carrier, while a shutter is open. First and second detectors for detecting the card passing therethrough are provided between the insertion port and shutter, and between the shutter and the carrier. The time difference between the detecting signals from the first and second detectors are compared with a standard time, and when the compared values are different, the inserted card is backwardly conveyed and outwardly ejected from the housing through the insertion port by the conveying mechanism.
