Card game cheat detector

Abstract

A fraud detection device 10 is provided at a table 1, and it detects a fraud in a card game that is played on the table 1. The fraud detection device 10 obtains entering card information to identify an entering card that is a card entering each game. The entering card information is stored while a game is being played. The fraud detection device 10 also obtains leaving card information to identify a leaving card that is a card leaving a game. Whether an entering card and a leaving card are identical or not is judged by comparing the entering card information and the leaving card information. The judgment result is outputted using an indicator. A fraud in a card game can be detected on the spot.

Description

TECHNICAL FIELD [0001] The present invention relates to a card game fraud detection device, and specifically relates to a device for detecting a fraud in a card game that is continuously played on a table. BACKGROUND ART [0002] One of devices of this kind is disclosed in International Publication WO 02 / 064225 A1. In the document, a code representing a group (or set) to which a card belongs is provided on the card by printing or the like. An inspection device in FIGS. 6 and 8 in the document reads a code from each card of a used group (see pages 15 to 17). Based on a code read from a card, the inspection device then judges whether an abnormal card is mixed in the group or not. [0003] The above-mentioned conventional device is conducive to preventing fraud by inspecting whether a card belongs to a predetermined group or not. However, it may be difficult for such a device to detect a fraud on the spot when a fraud is committed. [0004] In Baccarat, for example, cards are dealt to two pl...

Benefits of technology

[0009] Another purpose of the invention is to provide a device that can detect a fraud with a relatively simple and inexpensive configuration.

[0044] The card mark reading device of the invention preferably comprises a guide means for guiding a card so as to make a mark row of the card pass through the detection means. The guide means may comprise a rail for guiding a card when the card slides, the rail being provided to protrude from a table on which a card game is played. In this case, a positional relationship between the detection means and the rail is set up in such a way that a mark row passes through the detection means when the card slides with a side of the card being in contact with the rail. The invention allows the number of marks on a card to be determined reliably.

Problems solved by technology

However, it may be difficult for such a device to detect a fraud on the spot when a fraud is committed.

In addition, various inspection devices have been proposed besides the above-mentioned conventional device, but many conventionally proposed devices comprise a mechanism to successively transfer a lot of cards in order to inspect the whole group at a time, and they are relatively large.
