  The CR unit 50 (CR board CPU) is bus-connected to a relay base (information receiving means) 80 for the CR unit. In the block diagram of FIG. 3, the relay base 80 for the CR unit is depicted as a member around the CR unit 50, but the actual location is inside the housing of the pachislot machine 1. In addition, the main board CPU 60 and the sub board CPU 70 are also connected to the relay base 80 for the CR unit by a bus. The relay base 80 for the CR unit is a base for relaying the main board CPU 60, the sub board CPU 70, and the CR board CPU, and the CR unit 50, the main board CPU 60, Information is communicated between the substrate CPUs 70.

  Hereinafter, communication contents via the relay infrastructure 80 will be described. Communication between the CR unit 50, the main board CPU 60, and the sub board CPU 70 is related to the game medium lending process and the game recording medium return process. When the menu screen is displayed on the liquid crystal display device 5 by the operation of the selection switch 9a connected to the sub-board CPU 70 and the coin lending menu is selected, the selection menu is determined by the operation of the confirmation switch 9b. A lending request signal is transmitted from the board CPU 70 to the main board CPU 60 via the relay base 80 for the CR unit. Receiving this signal, the main board CPU 60 gives the CR unit 50 the frequency corresponding to the requested number of borrowed coins from the remaining number of valuable values recorded in the prepaid card via the relay unit 80 for the CR unit. Send a command signal to subtract only. Upon receiving the command signal, the CR unit 50 subtracts the valuable value for the corresponding frequency and re-records the remaining frequency after the subtraction on the prepaid card. Further, the main board CPU 60 performs a process of paying out the requested number of coins and updates the display of the stored number of the stored number display 11. When the prepaid card is not inserted into the CR unit 50, the operation switch 9 (9a, 9b) is used when the frequency of the valuable value recorded on the prepaid card is less than the required number of coins to be lent. ) Lending requests cannot be accepted.

  When the card return menu is selected by the operation of the selection switch 9a on the menu screen displayed on the liquid crystal display device 5 and is determined by the confirmation switch 9b, the sub board CPU 70 passes through the relay base 80 for the CR unit. A card return request signal is transmitted to the main board CPU 60. Upon receiving this signal, the main board CPU 60 sends a command signal to the CR unit 50 via the CR unit relay base 80 so that the prepaid card inserted in the CR unit 50 is discharged from the card return slot 51. Send. Upon receiving the command signal, the CR unit 50 returns the prepaid card and turns off the card display 52 to notify that the prepaid card is not inserted into the CR unit 50.

  In addition, communication regarding the display of the selection instruction screen on the liquid crystal display device 5 based on a predetermined condition is performed between the CR unit 50, the main board CPU 60, and the sub board CPU 70. The contents of this communication will be described according to the flowchart shown in FIG. If the CR board CPU determines in step 81 that a prepaid card has been inserted into the CR unit 50, the process proceeds to step 82 to determine whether or not the prepaid card has a valuable value balance (remaining frequency). When a coin lending request is made, it is determined by the CR board CPU (discriminating means) whether or not there is a remaining number enough to answer the lending request. Here, the number of coins requested for lending varies depending on the specifications of the pachislot machine. For example, the number of coins required for playing a game of 10, 30 or the maximum storage number of the storage device, or even one game. The number of sheets etc. are mentioned.

  If it is determined in step 82 that there is no balance of the prepaid card, the process proceeds to step 88, and the prepaid card return control process is performed by the CR board CPU. At this time, information indicating that there is no balance in the prepaid card is transmitted from the CR board CPU to the main board CPU 60 and the sub board CPU 70 via the relay unit 80 for the CR unit. On the other hand, if it is determined in step 82 that there is a balance of the prepaid card, there is no balance in the prepaid card from the CR board CPU to the main board CPU 60 and the sub board CPU 70 via the relay board 80 for the CR unit. The information indicating that the number of coins stored in the storage device (RAM) (stored number) is the number of coins required to play one game (specified number). Is determined by the main board CPU60. Here, the specified number is the number of inserted sheets required to play one game, and varies depending on the specifications of the pachislot machine. If it is a pachislot machine that can be arbitrarily selected, it will be one of the minimum BET.

  In step 83, if the main board CPU 60 determines that the number of stored sheets is larger than the specified number, information to that effect is transmitted from the main board CPU 60 to the sub board CPU 70 via the relay unit 80 for the CR unit. At the same time, one game is played in step 84, and this process is repeated until the stored number becomes smaller than the specified number. On the other hand, when the main board CPU 60 determines that the number of stored sheets is less than the specified number in step 83 (when a predetermined condition is satisfied), the information to that effect is transmitted via the relay unit 80 for the CR unit. In addition to being transmitted from the main board CPU 60 to the sub board CPU 70, in step 85, the sub board CPU 70 performs control to display a coin lending screen and a card return screen (selection instruction screen) on the liquid crystal display device 5.

  Subsequently, in step 86, the sub-board CPU 70 determines whether or not a menu related to coin lending has been selected. If it is determined that the menu has been selected, information indicating that is displayed as a relay for the CR unit. The data is transmitted from the sub board CPU 70 to the main board CPU 70 and the CR board CPU via the board 80. Upon receiving this information, the main board CPU 60 pays out the number of coins requested for lending to the tray 24, and the CR board CPU calculates the number of valuables corresponding to the number of coins requested for lending from the remaining number of prepaid cards. A coin lending process is performed by subtraction (step 89). When the coin lending process is completed, the process returns to step 82, and the processes of the above steps are repeated.

  In this embodiment, the balance of the prepaid card is determined every time the coin lending process is performed. For example, even when the coin lending process is not performed, the prepaid card is inserted. During this period, the main board CPU 60 may detect the valuable value balance of the prepaid card every predetermined period, and compare it with the previous detected balance of the prepaid card. As a result, it is possible to continue to recognize the valuable value balance of the inserted prepaid card, and to detect and prevent fraud from changes in the balance.

  On the other hand, if it is determined in step 86 that the menu related to coin lending has not been selected, the process proceeds to step 87, where it is determined whether or not the menu related to returning the prepaid card has been selected. Is done by. If it is determined in step 87 that the information has been selected, information to that effect is transmitted from the sub board CPU 70 to the main board CPU 70 and the CR board CPU via the CR unit relay board 80, and this information is received. In step 88, the CR board CPU performs a prepaid card return process. On the other hand, if it is determined in step 87 that the card return menu has not been selected, the process returns to step 85 and the processing of each step is repeated.

  The processing content of the flowchart described above is based on the premise that a prepaid card is inserted in the CR unit 50. Therefore, in the state where the prepaid card is not inserted, the selection instruction screen is not displayed on the liquid crystal display device 5 even if the stored number is less than the specified number. However, it is not limited to such a form, and in order to smoothly advance the game, even if the prepaid card is not inserted into the CR unit 50, it is stored in the storage device (RAM). When the main board CPU 60 determines that the number of stored coins is less than the prescribed number required to play one game, the message “There are no coins. What do you want to do?” Is displayed on the liquid crystal display device 5. Such a form may be sufficient.

  The predetermined condition in the form shown in FIG. 3 is that the balance of the number of stored game media, that is, the number displayed on the stored number display 11 is less than or equal to the input number required to play one game. However, the predetermined condition is not limited to this form. For example, the number of coins that the player has inserted to play a game is compared with the number of coins that were previously paid out. The selection instruction screen may be displayed on the liquid crystal display device 5 on condition that the value obtained by subtracting the inserted number from the number is less than the specified number. That is, in the flowchart shown in FIG. 3, in place of step 83, a determination may be made as to whether or not the value obtained by subtracting the number of inserted sheets from the number of loans is smaller than the prescribed number.

  Further, for example, the selection instruction screen may be displayed on the liquid crystal display device 5 on condition that the settlement button 19 is pressed by the player. That is, in the flowchart shown in FIG. 3, instead of step 83, it may be determined whether or not the “settlement button has been operated”.

  Next, the selection instruction screen displayed on the liquid crystal display device 5 will be described. FIG. 5 shows an example of the selection instruction screen. For example, when a predetermined condition is established that the number of stored sheets is less than a specified number, selection of whether to lend coins or return prepaid cards to the liquid crystal display device 5 as shown in FIG. Is displayed. On the other hand, the player operates the operation switch 9 (9a, 9b) and selects one according to the instruction. The selection switch 9a is a switch for selecting the selection content on the selection instruction screen displayed on the liquid crystal display device 5, and the confirmation switch 9b is a switch for confirming the selection content. Note that even when the predetermined condition that the value obtained by subtracting the number of inserted sheets from the lent number is less than the specified number is satisfied or when the predetermined condition that the settlement button is operated is satisfied, FIG. A screen similar to the screen shown in FIG.

  Each time the selection switch 9a is pressed, the position of the item to be selected moves one by one and changes cyclically. The display of the selected position is displayed by, for example, reverse display or border display. FIG. 5A shows a state where coin lending is selected. When the confirmation switch 9b is pressed in FIG. 5A, coin lending is determined, and an effect image (FIG. 5B) is displayed on the liquid crystal display screen 5 informing that the medal is being lent. . By using the liquid crystal display device 5 and its operation switch 9 (9a, 9b) not only as game information display means of the pachislot machine 1, but also as game medium lending means and game recording medium return means, a conventional pachislot machine is provided. It can be changed to a CR-compatible pachislot machine without any major modifications to the machine structure.

  At this time, a rental request signal is transmitted from the sub-board CPU 70 to the CR unit 50 via the CR unit relay board 80 based on the depression of the confirmation switch 9b. Based on this signal, the CR unit 50 subtracts the remaining number of valuables recorded on the prepaid card by the amount corresponding to the requested number of borrowed coins and records the subtracted remaining number on the prepaid card. Try again. Further, the CR unit 50 transmits information related to the lending request to the main board CPU 60 via the relay base 80 for the CR unit. The main board CPU 60 adds the lent number of coins based on the transmitted information to the storage device (the stored number display 11) or pays out the lent coins to the receiving tray 24. Further, the CR unit 50 transmits information related to the lending request to the sub-board CPU 70 via the CR unit relay board 80. The sub board CPU 70 displays on the liquid crystal display device 5 the remaining frequency of the prepaid card after being subtracted based on the transmitted information.
