Card cover recognition device for automatic card dispenser

Abstract

A card cover recognition device for an automatic card dispenser comprises a bar code and a recognizer, wherein the bar code comprises a bar code label and a radio frequency label, the bar code label comprises a label base body, an encoding zone and a numbering zone, the encoding zone comprises identification blocks, and the identification blocks are black or white; the recognizer comprises a bar code recognition device and a radio frequency recognition device; the bar code recognition device comprises a plurality of reflective infrared photoelectric sensors, and each reflective infrared photoelectric sensor corresponds to one identification block; when the identification blocks are black, the reflective infrared photoelectric sensors output low electric level; when the identification blocks are white, the reflective infrared photoelectric sensors output high electric level; the bar code recognition device is connected with a bar code decoding circuit, corresponding positions are set 0 by the bar code decoding circuit when the low electric level is output by the reflective infrared photoelectric sensors, and corresponding positions are set 1 when high electric level is output. The card cover recognition device has the advantages that the card cover code recognition efficiency and recognition quality can be ensured.

Description

Technical field [0001] The invention relates to components of an automatic licensing machine, in particular to a card sleeve recognition device used for the automatic licensing machine. technical background [0002] In the bridge game, due to the needs of the game system, the cards issued by the dealer are often put into the designated numbered deck in a specific order. Because the number of bridge decks used in each round of the bridge game is large, traditionally rely on Manually placing the designated numbered decks into the dealer's machine, it is easy to make mistakes of placing cards in non-designated decks, which affects the conduct of the bridge game and its fairness. [0003] The existing licensing machine recognizes the card sleeve by pasting a bar code on the card sleeve and setting a bar code scanning device on the licensing machine. After the card sleeve is inserted into the licensing machine, the bar code is aligned with the bar code scanning device, and the bar code ...
