Card turning device and card turning method of poker machine

Abstract

The invention discloses a card turning device and a card turning method of a poker machine. The card turning device comprises a controller, a card turning mechanism, an identification mechanism and acard feeding mechanism, and a detection mechanism comprises a detection element box camera; a through hole is formed in the side wall x of the upper end of a card turning box; the camera is mounted atthe through hole; the value range of the vertical distance M between the center of the through hole and the left side wall y of the card turning box is shown in the specification: M is greater than the vertical distance F between the playing card symbol and the proximal edge of the playing card symbol and smaller than the vertical distance F + 5mm between the playing card symbol and the proximaledge of the playing card symbol; the distance G from the playing card symbol to the edge of the front end of the card turning box is equal to the vertical distance R from the playing card symbol to the front edge of the card turning box; and the value range of the vertical distance H from the playing cards in the card turning box is H being greater than 3mm and less than 10mm. Whether the playingcards are stacked or not is determined by detecting the length of the playing cards, automatic identification and processing of stacked cards are achieved, the card turning order is optimized, and theplaying card image acquisition efficiency is high and power consumption is low.

Description

technical field [0001] The invention relates to the technical field of poker machines, in particular to a card turning device and a card turning method of a poker machine. Background technique [0002] Poker is a kind of entertainment that people like. After playing a game of cards, players need to manage their own cards, shuffle them and deal them out. In order to save the time of dealing cards, people have invented an automatic card dealing machine to deal cards. For example, the patent document with the publication number CN201164714Y discloses a four-port card dealing machine for playing cards. The card shuffling differential driven by the shuffling motor has four conveyor belts connected to the card issuing mechanism evenly distributed around it. The conveyor belts are driven by the conveyor motor, and each conveyor belt is equipped with a sorting wheel on one side and a card sorting wheel on the other side. A stopper matched with the board management wheel, a spiral d...

AI Technical Summary

Problems solved by technology

[0007] 1. The image acquisition efficiency is low. The camera needs to continuously collect images of the poker cards in the flop box. In some poker machines, in order to ensure the accuracy of the recognition of the front and back of the poker cards, two or more cameras are installed, which consumes power Serious, and will generate a large number of invalid images, high requirements for the configuration of the image processing module, resulting in high production and maintenance costs

[0008] 2. Cannot automatically identify and deal with stacked cards. When there is a problem with stacked cards, the card flop will be unstable, the flop efficiency will be low, and even the system will crash.

[0009] To sum up, the existing poker machine flop devices still have shortcomings in terms of the accuracy of poker image acquisition, the efficiency of card face recognition, the judgment of stacking problems, the power consumption and the stability of flopping cards, etc. It is necessary to carry out more refined improvements to the size and structure of the existing card flipping device
