  After step S101, the game control unit 23a performs a game process (step S102), and updates the number-of-balls data 22a (step S103). After updating the number of possessed balls 22a, the regular notification unit 23c refers to the time measurement result of the timer 25 to determine whether it is the timing of regular notification (step S104).

  If it is the timing of regular notification (step S104; Yes), the regular notification unit 23c reads the number of possessed balls data 22a from the storage unit 22 and notifies the inter-card card processing machine 10 of the number of retained balls (step S105). ).

  After the completion of step S105 or when it is not the timing of regular notification (step S104; No), the possession management unit 23b determines whether or not a possession return instruction has been received from the inter-card processing machine 10 (step S106).

  If no coin return instruction has been received from the inter-card card processing machine 10 (step S106; No), the process proceeds to step S102. On the other hand, if a ball return instruction is received from the inter-card processing machine 10 (step S106; Yes), the end notification unit 23d reads the internal ball number data 22a from the storage unit 22, and determines the number of internal balls The card processor 10 is notified (step S107), the number-of-balls data 22a is cleared to zero (step S108), and the process is terminated.

  Next, the processing procedure of the inter-card card processing machine 10 shown in FIG. 1 will be described. FIG. 7 is a flowchart showing a processing procedure of the inter-card card processing machine 10 shown in FIG. First, the inter-card card processing machine 10 determines whether or not a regular notice of the number of balls has been received from the enclosed game machine 20 after the start of the game by the enclosed game machine 20 (step S201).

  If the regular notification of the number of possessed balls is received from the enclosed game machine 20 (step S201; Yes), the upper limit calculator 10f4 calculates the upper limit 10e3 based on the number of possessed balls received from the enclosed game machine 20. (Step S202), the upper limit 10e3 of the storage unit 10e is updated (Step S203).

  After step S203 or when the regular notification of the number of possessed balls has not been received from the enclosed gaming machine 20 (step S201; No), the data management unit 10f1 determines whether or not the card return button 18 has been pressed. Determination is made (step S204).

  If the pressing operation of the card return button 18 has not been performed (step S204; No), the inter-card card processing machine 10 proceeds to step S201. On the other hand, if the pressing operation of the card return button 18 is performed (step S204; Yes), the data management unit 10f1 transmits a ball return instruction to the enclosed game machine 20 (step S205), and the enclosed game machine The number of possessed balls is received from 20 (step S206).

  The comparison control unit 10f5 reads the upper limit value 10e3 from the storage unit 10e, and compares the number of balls received from the enclosed game machine 20 with the upper limit value 10e3 (step S207). If the number of possessed balls received from the enclosed game machine 20 is equal to or less than the upper limit value 10e3 (step S207; No), the card processing unit 10f3 performs a card return process (step S208) and ends the process. Specifically, the card processing unit 10f3 associates the number of balls received from the enclosed game machine 20 and the prepaid value data 10e2 read from the storage unit 10e with the card, and discharges the card.

  On the other hand, if the number of possessed balls received from the enclosed game machine 20 exceeds the upper limit value 10e3 (step S207; Yes), the comparison control unit 10f5 performs error processing (step S209) and ends the processing. . Specifically, the comparison control unit 10f5 suppresses card ejection and notifies an error to a clerk terminal.

  As described above, in the first embodiment, the enclosed game machine 20 stores the number-of-balls data 22a in the storage unit 22 and periodically notifies the inter-card card processor 10 at a predetermined time interval. The inter-card processing machine 10 calculates the upper limit value of the number of balls based on the number of balls that are regularly notified by the enclosed game machine 20. The inter-card processing machine 10 compares the upper limit with the number of balls that the enclosed gaming machine 20 transmits to the inter-card processing machine 10 when the player presses the card return button 18. Based on the result of the comparison, it is configured to control card discharge, so each of the fraud that electronically increases the number of possessed balls managed in the enclosed game machine and the equipment pretending to be an enclosed game machine It is possible to efficiently detect fraud that notifies the stand device of the number of bobbed balls.

  In addition, although the present Example 1 demonstrated the case where the number of possessed balls notified based on the retained ball return instruction and the upper limit 10e3 were compared, the number of retained balls notified by the regular notification was compared with the upper limit 10e3. You may make it do. Thus, by comparing periodically during the game, when an abnormality occurs in the number of balls due to an unauthorized operation or a failure, the occurrence of the abnormality can be detected promptly.

  In the first embodiment, the upper limit value 10e3 is calculated and stored in the storage unit 10e every time the number of possessed balls is notified by regular notification. However, the number of possessed balls notified to the storage unit 10e is exemplified. You may comprise so that it may memorize | store and may calculate an upper limit from the last number of possession balls memorize | stored in the memory | storage part 10e at the timing which compares by the comparison control part 10f5.

In addition, when the time interval from the previous periodic notification to the notification based on the ball return instruction is less than the predetermined value, the notification was made based on the number of balls and the ball return instruction notified by the previous periodic notification. You may make it compare with the number of balls. Furthermore, the upper limit value may be calculated using the time interval from the previous regular notification to the notification based on the ball return instruction. In this case, the value of the upper limit value 10e3 is “A”, the number of possessed balls notified from the previous trial machine 20 is “B”, and the time interval from the previous regular notification to the notification based on the retained ball return instruction is “ “T minutes”, the number of pachinko balls fired per minute is “C”, the maximum number of balls that a player can acquire between Δt is “D”, and the error is “X”
A = B−C × T + D + X
The upper limit value will be obtained by the following formula.

  By the way, in the said Example 1, although the case where a pedestrian card processing machine determined the presence or absence of fraud based on the number of possession balls regularly received from the enclosed game machine was shown, this invention is limited to this. It is not a thing. In the second embodiment, a case will be shown in which the inter-card card processing machine acquires a driving ball signal and a prize ball signal output by the enclosed game machine and uses them for the determination of fraud.

  First, the system configuration of the gaming system according to the second embodiment will be described. FIG. 8 is a diagram illustrating a system configuration of the gaming system according to the second embodiment. As shown in the figure, this gaming system includes a plurality of enclosed gaming machines 120, a table card processing machine 110 provided corresponding to each enclosed gaming machine 120, a card management device 40, and a member. A management device 50, a payment machine 60, a prize management device 70, and a hall computer 80 are connected via a communication line 90. In addition, the same code | symbol is attached | subjected to the component similar to Example 1, and description is abbreviate | omitted.

  The enclosed game machine 120 is a device such as a pachinko machine in which a player plays a pachinko game by driving a pachinko ball enclosed in the device into the game area. This encapsulated gaming machine 120 can add the number of balls when the inter-card processing machine 110 performs the ball lending process, and can drive a pachinko ball into the gaming area within the range where the balls are present. Further, if the pachinko ball that has been struck wins, the number of pachinko balls won is added to the number of balls.

  The enclosed gaming machine 120 transmits a ball signal indicating the number of pachinko balls that have been driven into the game area to the hall computer 80 and sends a ball signal indicating the number of prize balls obtained by winning to the hall computer 80. Send. The shot ball signal and prize ball signal are transmitted as a pulse signal of one pulse every predetermined number of balls (for example, 10 balls).

  The inter-card processing unit 110 performs prepaid value management, pachinko ball lending, card return processing, and communication with the card management device 40. The inter-card processing machine 110 stores the prepaid value for the banknote when the banknote inserted by the player is received, and subtracts a predetermined number of prepaid value when a predetermined ball lending operation is performed. Meanwhile, the enclosing game machine 120 is caused to add the number of possessed balls corresponding to the subtracted prepaid value. The inter-card processing machine 110 transmits a ball lending signal indicating the number of balls lent by the ball lending operation to the hall computer 80. The ball lending signal is transmitted as a pulse signal of one pulse every predetermined number of balls (for example, 10 balls).

  Further, when the inter-card processing machine 110 receives the card, it stores the prepaid value associated with the card, and the number of possessed balls associated with the card is set as the number of possessed balls of the enclosing game machine 120. Let them add. When the card return operation is accepted, the inter-card processing machine 110 transmits a ball return instruction to the enclosed game machine 120 and receives a notification of the number of balls from the enclosed game machine 120, and the enclosed type A process of discharging the number of balls informed from the gaming machine 120 and the prepaid value stored in the inter-card processing machine 110 in association with the card is performed.

  Further, the inter-card processing machine 110 receives the shot ball signal and the prize ball signal transmitted from the enclosed game machine 120, and uses the shot ball signal and the prize ball signal to perform the enclosed game based on the ball return instruction. A threshold value to be compared with the number of possessed balls notified from the machine 20 is calculated. If the number of balls is notified from the enclosed game machine 120 based on the ball return instruction, the inter-card processing machine 110 determines the consistency of the number of balls in comparison with the threshold, Discharge.

  The hall computer 80 collects game machine usage information at the amusement store by using the driving ball signal and prize signal received from the enclosed game machine 120 and the ball rental signal received from the inter-card processing machine 110. -A device to be managed. The hall computer 80 can analyze how the gaming machine is used by performing sales calculation and error determination using the collected usage information of the gaming machine.

  Next, the internal configuration of the inter-card card processing machine 110 and the enclosed game machine 120 shown in FIG. 8 will be described. FIG. 9 is a block diagram showing the internal configuration of the inter-card card processing machine 110 and the enclosed game machine 120. Compared with the internal configuration of the inter-card card processing machine 10 shown in FIG. 3, the internal configuration of the inter-card card processing machine 110 shown in FIG. 9 further includes a pulse generation unit 10d, and the storage unit 10e has an upper limit value 10e3. Instead, the threshold value 10e4 is stored, and the control unit 10f is different from the upper limit value calculation unit 10f4 in that it includes a threshold value calculation unit 10f6. Further, the internal configuration of the enclosed game machine 120 shown in FIG. 9 does not have the timer 25 but has the pulse generator 26 and the control compared to the internal configuration of the enclosed game machine 20 shown in FIG. The difference is that the unit 23 does not have the regular notification unit 23c. Since other configurations and operations are the same as the internal configuration shown in FIG. 3, the same components are denoted by the same reference numerals and description thereof is omitted.

  The pulse generation unit 10d of the inter-card processing machine 110 includes the enclosed game machine 20 so that the data management unit 10f1 subtracts a predetermined number (for example, 10 times) of the prepaid value data 10e2 and adds a corresponding number of balls. If a notification is made, a ball lending signal of 1 pulse is generated every predetermined number (for example, 10 balls) and transmitted to the hall computer 80.

The threshold value 10e4 stored in the storage unit 10e is a threshold value used for comparison with the number of possessed balls notified from the enclosed game machine 120 based on the ball return instruction. Specifically, the threshold value 10e4 is “A”, the original number of balls when the card is inserted is “B”, the total number of balls is “C”, and the total number of balls is “ D ”, if the total number of prizes is“ E ”and the error is“ X ”,
A = B + C-D + E + X
It is calculated by the following formula. Note that the original number of possessed balls “B” is 0 in the case of a cash game.

  The threshold value calculation unit 10f6 receives the shot ball signal and the prize ball signal transmitted from the enclosed game machine 120, obtains the total number of shot balls and the total number of prize balls, and calculates the threshold by the above-described calculation formula. The threshold value 10e4 is updated by calculating the value 10e4 and storing it in the storage unit 10e.

  Therefore, the comparison control unit 10f5 determines the consistency of the number of possessed balls by comparing the number of retained balls notified from the enclosed game machine 120 based on the retained ball return instruction with the threshold 10e4. The processing for the comparison result is the same as in the first embodiment.

  The pulse generator 26 of the encapsulated gaming machine 120 obtains the number of prize balls using a sensor provided in the game area, and transmits a one-ball prize signal for every ten balls. Similarly, the pulse generator 26 transmits a 1-shot driving ball signal for every 10 balls in the number of driving balls.

  Since the control unit 23 does not have the regular notification unit 23c, the regular notification unit 23c is not notified of the number of possessed balls. The number of balls will be notified.
