Abstract

A bar-code reading system, a bar-code reader, a recording medium for the bar-code reader, and a method of reading a bar code, and of the present invention are disclosed. The bar-code reading system of the present invention is able to read the information represented by a bar code on a card with reliability and with high accuracy by passing the card through the card reader one time in spite of the presence of defect in any pixel of the bar code printed on the card. The bar-code reading system has a reading device for reading a medium on which a bar code is printed, by an image sensor having photo-electric conversion elements arranged in line, and a processing device for performing a predetermined process on the basis of information read by the reading device. The bar-code reading system is configured to read the bar code under the conditions in which the reading line of the image sensor and the direction of relative displacement of the card cross each other at a predetermined angle. The image sensor reads the bar code several times during the relative parallel displacements of the image sensor and the card. The bar-cord reader has a card insertion slot for receiving the card, a card ejection slot for removing the card read by the image sensor, and a transporting device for transporting the card to either the insertion slot or the ejection slot.
