CARD ORIENTATION DETECTION METHOD AND APPARATUS AND CARD

摘要

A card orientation detection method and apparatus and a card. The card orientation detection apparatus (200) comprises: a detection unit (12, 25), for detecting a movement distance of a card (10) from arriving at a first detection point to leaving a second detection point in a card transmission channel (27), wherein when the card (10) moves in the card transmission channel (27) under a first orientation, the detected movement distance of the card (10) is a first distance, and when the card (10) moves in the card transmission channel (27) under a second orientation, the detected movement distance of the card (10) is a second distance, wherein the first distance is not equal to the second distance; and a judgment unit (14, 20, 40, 60), for determining that the orientation of the card (10) is the first orientation when the detected movement distance is the first distance, and determining that the orientation of the card (10) is the second orientation when the detected movement distance is the second distance. By means of the detection apparatus, the card detection apparatus (200) can realize card orientation detection all the time when the card (10) is sent into the card transmission channel (27) in two different directions under each orientation.
