  The control device 15 is a control means for grasping the trend of the chip based on the identification information read by the identification information reading device 14 and writing the identification information by the identification information reading device 14 as necessary.

  As shown in FIG. 4, an identification information writing device 13, an identification information reading device 14, a display device 17, and a recording device 18 are connected to the control device 15, respectively. The chip collection device 16 is connected to an identification information writing device 13 and an identification information reading device 14 provided therein. The control device 15 includes a CPU, a ROM, a RAM, and the like. Thus, a recording unit, a processing unit, and an output unit are configured.

  The recording unit is management means for recording and managing the identification information read by the identification information reading device 14 as well as information on the game of the day at the casino. Specifically, information written in the identification information recording device 12 of the chip 21 is recorded in association with the chip 21.

  The processing unit performs various processes based on information recorded in the recording unit. Specifically, the function of the flowchart shown in FIG. 12 is stored.

  The output unit appropriately outputs the result of the processing in the processing unit to the display device 17.

  The display device 17 is a display means for displaying the trend of the chip grasped by the control device 15. Specifically, as shown in FIG. 10, the total number of chips, missing number information, casino table 1 information, casino table 2 information, casino table 3 information, and casino table 4 information are displayed. The total number of chips is the total number of chips 21 used in the casino. The chip 21 used in the casino is supplied with a consecutive number from a young number when it is exchanged for cash, so if it is not collected at all, it is a serial number without a missing number. It is in a normal state. The missing number information is displayed when a part of the chip 21 used in the casino has been collected or lost and is missing. Casino table information is displayed for the number of units installed in the casino. In the individual casino table information, as shown in FIG. 11, each serial number, the number and number for each chip amount, the number and number for each chip color, the number and number for each chip size, and the like are displayed.

The recording unit of the control device 15 records the trend of the chip 21 of the day, whereas the recording device 18 records information for several weeks or months. The recording device 18 is composed of recording means such as a hard disk. The recording device 8 organizes and records each day and creates a database. This is for examining the trend of the chip 21 in the game several days ago or several months ago if necessary.

  The gaming chip monitoring system 1 configured as described above operates as follows. This will be described based on the flowchart of FIG.

  The traveler exchanges cash for the chip 21 using a chip exchange. At this time, in the chip exchange, the identification information writing device 13 writes the identification information in the identification information recording device 12 of the chip 21 to be replaced (step S1). The identification information written by the identification information writing device 13 is recorded in the recording unit of the control device 15 in association with the chip 21 on which it is written. When the identification information is written in the chip 21 in advance, the identification information is read by the identification information reading device 14 and recorded in the recording unit of the control device 15.

  A traveler plays a game using the chip 21 exchanged by the chip exchange. For example, the chip 21 used in the card game is collected by the dealer during the game and put into the chip collecting device 16. As a result, the chip recognition unit 31 of the chip collection device 16 accepts the chip 21 (step S2) and passes it in close proximity to the non-contact communication unit 35. At this time, the identification information of the chip 21 is read in association with the chip 21 by the identification information reading device 14 and processed by the processing unit of the control device 15. Specifically, the read identification information is compared with the identification information recorded in the recording unit of the control device 15. Thereby, it is determined whether the serial numbers are duplicated (step S3). If it overlaps, it is determined as an illegal chip. If there is no overlap, it is determined whether the number is greater than the maximum consecutive number of chips 21 supplied by the casino (step S4). If it is larger, it is determined as an illegal chip. If it is smaller, it is determined whether the amount is correct (step S5). If there is no amount, it is determined to be an invalid chip. If yes, it is determined whether registration, identification information, and color are correct (step S6). If not, it is determined as an invalid chip. If yes, it is determined whether authentication is OK or not (step S7). If it is not OK, it is determined as an illegal chip. If it is OK, the process returns to step S2 and the above process is repeated.

  The above processing is appropriately displayed on the display device 17.

  As described above, even if an illegally forged chip is brought into the casino, it can be surely detected. Thereby, it is possible to prevent the deterioration of the profits of the casino due to counterfeit chips or the like.

  In addition, it is possible to grasp the game propensity of the player. Each identification information reading device 14 recognizes the chip 21 used in each game gaming table 27 and grasps the trend thereof, so that which game gaming table 27 uses which chip 21 is used. , You can grasp the game propensity of the player. In addition, when the identification information (chip color or the like) that links the chip 21 and a specific player (customer or the like) is used, the gaming tendency of the customer or the like can be grasped.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. Since the entire configuration of the game chip monitoring system 11 is the same as that of the first embodiment, the same members are denoted by the same reference numerals and description thereof is omitted here.

  This embodiment is characterized by the processing mode of the control device 15. In the first embodiment, after one piece of identification information is written to one chip 21, it is not rewritten. However, the identification information may be appropriately selected and written at any time. For example, the control device 15 appropriately creates identification information based on a random number table, or selects a specific one from a large number of identification information created in advance, and writes it in the identification information recording device 12 of the chip 21. At the same time, it is recorded in the recording unit of the control device 15.

  This makes it impossible for outsiders and related parties to make a chip in which the same identification information is written because the random number is unknown. Thereby, the regular chip 21 can be reliably identified, and the chip 21 cannot be forged.

  In addition, the control device 15 may include an identification information selection processing unit that selects identification information regularly or irregularly. The identification information selection processing unit writes the identification information selected regularly or irregularly, for example, based on a random number table, to the identification information recording device 12 of the chip 21 by the identification information writing device 13 as needed. Is recorded in the recording unit of the control device 15 in correspondence with the chip 21 on which is written. As a mode in which the identification information writing device 13 writes the identification information, for example, the chip collection device 16 is used. The identification information of the chip 21 put into the chip collecting device 16 is rewritten and reused in the chip exchanger.

  As a result, even if the identification information of the counterfeit chip matches the identification information of the regular chip 21, it does not match at the next rewriting. This makes it impossible for internal parties to match the identification information, and the use of counterfeit chips becomes almost completely impossible.

  Further, when the identification information selected by the identification information selection processing unit of the control device 15 regularly or irregularly is written to the identification information recording device 12 of the chip 21 by the identification information writing device 13 at any time, the previous writing operation is performed. A comparison processing unit that compares the identification information recorded in the identification information recording device 12 with the identification information recorded in the recording unit of the control device 15 to determine whether or not they match may be provided. Thus, the write operation is performed only when the identification information recorded in the identification information recording device 12 of the chip 21 matches the identification information recorded in the recording unit of the control device 15 by the processing in the comparison processing unit. Thus, even if the write operation is performed many times, the original chip 21 and each identification information are surely matched, and the regular chip 21 can be reliably identified.

  Next, the operation of the game chip monitoring system of this embodiment will be described with reference to FIG.

  First, it is determined whether or not a chip has been purchased with a chip exchanger (step S11). When the chip 21 is purchased, a random number is generated by the identification information writing device 13 that writes to the chip 21, the identification information including the random number is written, and the fact is recorded in the recording unit (step S12).

  Next, it is determined whether or not the identification information of the chip 21 has been read by any one of the identification information reading devices 14 (step S13). If none of the identification information reading devices 14 has read, the first processing is repeated. If it is read by any one of the identification information reading devices 14, it is compared with the identification information recorded in the recording unit (step S14). By this comparison, it is determined whether or not the read identification information matches the identification information recorded in the recording unit (step S15). If the identification information matches, the fact is recorded in the recording unit (step S16). Next, it is determined whether or not the position where the identification information is read is the chip collection device 16 (step S17). In the case of the chip collection device 16, the identification information writing device 13 rewrites the new identification information (step S18), records the new identification information in the recording unit (step S19), and repeats from the first process. If it is determined in step S17 that the chip collection device 16 is not used, the process is repeated from the first process.

  If the identification information does not match in step S15, it is determined that the chip is a forged chip, and that effect is displayed on the display device 17 (step S20). Next, it is determined whether or not the position where the identification information is read is the chip collection device 16 (step S21). In the case of the chip collection device 16, the forging chip is excluded by operating the exclusion means (step S22), and that effect is recorded in the recording unit (step S23). If it is determined in step S21 that the position where the identification information has been read is not the chip collection device 16, the process proceeds to step S23, and that effect is recorded in the recording unit.

  Next, the identification information of the chip 21 recorded in the recording unit is displayed on the display unit 17 (step S24). On the display device 17, the read identification information of the chip 21 and the like are displayed for each game gaming table 27, and the person concerned can grasp the trend of the chip while watching the display device 17.

  As described above, even when an illegally counterfeited chip is brought into the casino, it can be surely detected as in the first embodiment. Thereby, it is possible to prevent the deterioration of the profits of the casino due to counterfeit chips or the like.

  In addition, by grasping the trend of the chip, it is possible to grasp the game propensity of the player as in the first embodiment.
