A card unit (which may be abbreviated as CU hereinafter) 3 as an example of a gaming device is installed in a one-to-one correspondence with the P table 2 at a side position on the predetermined side of the P table 2. Yes. Note that the card unit is taken as an example of the gaming apparatus according to the present embodiment, but the present invention is not limited to this. It may be a calling lamp device or the like.

  The P stand 2 encloses a pachinko ball as an example of a game medium inside, and when the player operates the hitting operation handle 25, the firing motor 18 (see FIG. 4) is driven to make one shot of the enclosing ball. The game board 26 is configured so that it can be played one by one in the game area 27 in front of the game board 26. Specifically, a touch sensor is provided around the batting operation handle 25, and the player's hand touches the touch sensor while the player is operating the batting operation handle 25, and the player's hand. Is detected by the touch sensor, and the firing motor 18 is driven. In this state, the hitting momentum is adjusted in accordance with the amount of rotation of the hitting operation handle 25 by the player, and the ball is shot into the game area 27.

  The firing strength of the pachinko ball (hereinafter simply referred to as the firing strength T) can be adjusted in accordance with the amount of rotation of the hitting ball operating handle 25 (hereinafter also simply referred to as the handle operating amount), and the handle operating amount is increased. The firing intensity T increases accordingly. Therefore, the player can adjust the firing strength T so that the pachinko ball passes through the region he / she aims by adjusting the handle operation amount.

  The P stand 2 shown in FIG. 1 is a so-called first type pachinko gaming machine, and a variable display device (also referred to as a special symbol) 278 is provided in the center of the game area 27. In addition, the game area 27 is provided with a plurality of types of winning holes through which the inserted pachinko balls can be won. In the game area 27 shown in FIG. 1, one large winning opening (variable winning ball apparatus) 271, three normal winning holes 272, 273, 274 and three start winning holes 275, 276, 277 are shown. ing. In particular, the start winning opening 276 is configured by an electric tulip that can be changed between a first state (for example, an open state) that is advantageous to the player and a second state (for example, a closed state) that is disadvantageous to the player. .

  The variable display device 278 includes a variable display unit capable of variably displaying a plurality of types of identification information (symbols), and based on the detection signals of the start winning balls won in each start winning opening 275, 276, 277. Start variable display of multiple types of identification information. When the display result of the variable display device is a combination of specific identification information (for example, a glance), a big hit state is established and the big prize opening 271 is opened.

  A probable winning prize opening 271 a is arranged in the big winning prize opening 271. When the pachinko ball that has won the big prize opening 271 also wins the probability change prize opening 271a, the probability that a big hit will occur after the end of the current big hit state is improved (hereinafter also referred to as a probability variation state or simply a probability change state). Will occur.

  Further, the display result of the variable display device 278 becomes a combination of predetermined special identification information (for example, a combination of probability variation symbols such as 777) out of a combination of jackpot symbols (a slotted pattern), so that the probability variation big hit state And a probability variation state (probability variation state) in which the probability of occurrence of the jackpot is improved after the end of the jackpot state.

  Pachinko balls that have been driven into the game area 27 are won in any of the winning openings or are collected in the out opening 154 without winning. The pachinko balls won in any one of the winning openings and the pachinko balls collected in the out opening 154 are returned again to the hitting ball launch position through the collection path in the P stand 2. Then, when the player operates the hitting operation handle 25, the pachinko ball at the hitting position is again shot into the game area 27.

  An indicator 54 is provided at a position below the game area 27 in the P stand 2. The display 54 is composed of a liquid crystal display device, and displays various effect images linked to the display of the points, the remaining card amount, or the variable display device 278 to the player. The display 54 is formed integrally with the CU (card unit) 3 even if it is attached to the P stand (pachinko gaming machine) 2 independently of the CU (card unit) 3 as shown in FIG. It may be configured to be fitted to the front surface of the base (pachinko machine) 2. If the display 54 of the CU 3 is configured to be fitted to the front surface of the P base 2, the CU 3 and the P base 2 can be more strongly connected, so that fraud can be further prevented. In this case, fraud can be further prevented by preventing the connection and locking with the display 54 from being released unless the glass door 6 or the lower door provided with the hitting ball operating handle 25 is opened. .

  A 7-segment display 50 is provided below the display 54. The 7-segment display 50 includes a 7-segment LED display, and is controlled by a payout control unit 171 described later. The 7-segment display 50 displays the number of game balls to be described later, an error number of an error that has occurred, and the like.

  Further, a counting button 28 for counting from game balls to holding balls is provided at the left position of the hitting operation handle 25 on the P platform 2. In the present embodiment, the counting operation is repeatedly executed according to the time for which the counting button 28 is kept pressed. It should be noted that, regardless of the pressing duration time, if the button is pressed once, a predetermined number (for example, 100 balls) may be counted from the gaming ball to the holding ball, or the counting button 28 is pressed once. All of the game balls currently owned by the player may be counted regardless of the pressing time (regardless of whether the button is pressed for a long time). Further, the counting speed is further improved when a card return operation is performed, and a smooth card return process is realized.

  As described above, since the counting button 28 is provided on the P unit (pachinko gaming machine) 2 side, it is seated facing the P table 2 as compared with the case where the counting button 28 is provided on the CU (card unit) 3 side.

In particular, the game board 26 is different for each model of pachinko gaming machine developed by each company, while the front frame 5 is a common common frame regardless of the model. For this reason, it is sufficient for the game store to replace only the game board 26 when replacing a new stand.

<Configuration of card unit>
Next, the configuration of the CU 3 according to the present embodiment will be described with reference to FIG. This CU3 is a visitor card (also referred to as a general card) having a prepaid function, which is a game recording medium issued to general players who have not registered as a member, or a member player who has registered as a member in the playground. A membership card, which is a game recording medium issued to, is accepted. Visitor cards and membership cards are composed of IC cards.

  The CU 3 that accepts these cards has a function of converting the game value (for example, the remaining card amount, the number of balls, or the number of balls, etc.) owned by the player specified by the record information of the card into “game ball data”. . In the P stand 2, a ball game corresponding to the number of balls specified by the data of the game balls is made possible. That is, “game ball data” is data indicating the number of remaining balls that can be fired. In the following description, “game ball data” is simply referred to as “game ball” in the same manner as a stored ball and a holding ball.

  On the front side of CU3, a bill insertion slot 302 for inserting bills, a protruding portion 305 formed to project forward from the front side of the device, a card insertion / discharge port 309 for inserting a membership card or a visitor card, etc. Is provided. A membership card or a visitor card inserted into the card insertion / discharge port 309 is received by a card reader / writer (not shown), and information recorded on the card is read.

  In the protrusion 305 described above, on the surface facing the player, the display unit 312 and the member card ID recorded on the member card when the member card is received (also simply referred to as a card ID or C-ID). ) And a replay button 319 for performing a replay game using the number of stored balls specified by the member card ID.

  The display 312 displays the prepaid balance recorded on the inserted game recording medium (card) (also referred to as the card balance or simply the balance), but can display the number of game balls and various other information. In addition, the surface is configured with a transparent touch panel, and various operations can be input by touching various display items displayed on the display unit of the display 312 with a finger.

  When the replay button 319 is operated, if the number of possessed balls acquired by the player is recorded on the inserted card, a part of the number of possessed balls is withdrawn and converted into a game ball, and the converted game ball is converted into a converted game ball. Based on this, it is possible to play a game with the P stand 2. On the other hand, if the inserted card is a membership card and the number of possession balls is not recorded and the storage ball is recorded in the hall management computer, etc., a part of the storage ball is withdrawn and becomes a game ball. It is converted and the game by P stand 2 becomes possible. That is, when both the stored ball and the holding ball are stored in association with the inserted card, the holding ball is withdrawn preferentially. Separately from the replay button 319, a dedicated ball payout button for withdrawing the holding ball may be provided, and the replay button 319 may be a button dedicated to the withdrawal of the stored ball.

  Here, the “storing ball” is a ball deposited in the hall with a ball acquired before the previous day, and becomes a game ball by paying out the saving ball. The storage ball is a game medium deposited in a game hall, and is generally managed by a hall management computer or other management computer installed in the game hall.

  “Mochitama” is a ball acquired on the day and becomes a game ball by paying out the possessionball. The number of possessed balls is the number of balls that the player possesses as a result of the player playing the game with the gaming machine on the card, and the number of balls that have not yet been deposited in the game hall. That is. Generally, the number of balls that the player has acquired on the day of the game hall is called “mochidama”, and the number of balls that the player has acquired before the previous day and that has been deposited in the amusement hall is “save ball”. Say.

  A “game ball” is a ball that can be fired by a gaming machine. As described above, the data on the number of game balls is generated in exchange for withdrawing the remaining amount of the prepaid card, holding balls, or storing balls.

  Note that the number of possessed balls may be managed by a management device for managing the number of possessed balls set in the game hall. In short, the difference between “sold balls” and “mochidama” is the number of balls that have been deposited in the amusement hall as a result of a storage operation for depositing in the amusement hall, or is still deposited in the amusement hall. It is a point whether it is the number of balls of the stage which is not.

  In this embodiment, the stored ball data is not recorded directly on the membership card, but stored in association with the membership card number on a server installed in a game hall such as a hall management computer, and the corresponding storage ball is searched based on the membership card number. It is configured to be able to. On the other hand, Mochitama records directly on the card. However, the present invention is not limited to this, and both may be stored in the hall server 801 in association with the card number. In the case of a visitor card, Mochitama is recorded directly on the visitor card. However, the present invention is not limited to this, and the ball may be stored in the hall server 801 in association with the card number. When the hall server 801 stores the card number in association with the card number, data that can specify the time stored in the hall server 801 may be written on the card (member card, visitor card) and discharged. Also, the prepaid balance is written directly on a card (member card, visitor card) and discharged.

  Note that the timing for storing the holding balls in a card (member card, visitor card) or hall server is stored at regular intervals every time the counting button 28 is operated and counting processing is performed, for example. It is conceivable that the timing is such that it is stored in a lump or when the card is returned.

  Also, when the player finishes the game and returns the card from CU3, the possession ball stored in CU3 is temporarily stored in the hall server 801 as a stored ball, and the day when the player receives the card return When the card is inserted into the same or another CU3 again on the same day, only the possession balls for the day that are once stored as accumulated balls are stored again in the CU3, and the game balls are added within the range of the possession balls. You may be able to do it.

  The banknote inserted into the banknote insertion slot 302 is taken in by a currency discriminator (not shown), and its authenticity and banknote type are identified.

  An IR (Infrared) photosensitive unit (also referred to as an IR light receiving unit) 320, a ball lending button (also referred to as a lending button) 321, and a card return button 322 are further provided on the front side of the CU 3. The IR photosensitive unit 320 is an IR photosensitive unit 320 that receives an infrared signal from a remote controller (not shown) possessed by an attendant at a game arcade, converts it into an electronic signal, and outputs the electronic signal. The ball lending button 321 is a button for performing an operation (conversion operation to a game ball) for withdrawing the remaining amount recorded on the inserted card and using it for a game by the P stand 2. The card return button 322 is operated when the player ends the game, and the number of game balls determined at the end of the game on the inserted card (the number of balls at the time of card insertion−the number of conversions to game balls + count) This is an operation button for memorizing and discharging the number of possessed balls counted by the operation.

  Next, referring to FIG. 2, the P base 2 is opened and closed with respect to the frame-like outer frame 4 by a front frame (hereinafter also referred to as a cell) 5 and a glass door 6 with the left side edge as a swing center. It is provided as possible.

  A pair of upper and lower engaging protrusions 6a and 6b are provided in the vicinity of the edge of the front frame 5 opposite to the center of swing (the free end side). The engaging protrusions 6a and 6b are pressed downward by a spring (not shown). On the other hand, engagement receiving pieces 7a and 7b are provided at positions facing the engagement protrusions 6a and 6b of the outer frame 4. When the front frame 5 in the open state is pressed against the outer frame 4, the engagement protrusions 6a and 6b get over the engagement receiving pieces 7a and 7b, and the engagement protrusions 6a and 6b are moved downward by the urging force of the spring in the state of getting over. Move and become locked.

  Then, a clerk at the game hall inserts a key into the key hole 10 shown in FIG. 1 and performs an unlocking operation (for example, clockwise rotation), thereby a pair of upper and lower engaging protrusions 6a against the urging force of the spring, 6b is pushed upward, and as a result, the engagement projections 6a and 6b are disengaged from the engagement receiving pieces 7a and 7b to be unlocked, and the front frame 5 is released.

  Further, the front frame 5 is also provided with an engagement projection 8 for the glass door 6, and an engagement hole 9 is provided in the glass door 6 portion facing the engagement projection 8.

Although details will be described later, the security boards 325 and the CU control board 327 can be stably fixed by engaging the openings 360a and 360b with the protrusions provided on the CU control board 327.

  Here, on the substrate surface 330, electronic components such as a connector 510, a communication control IC 325a, and a security chip 325b are surface-mounted to form wiring patterns 340 and 342 (see FIGS. 6 and 7). It can be seen that no other electronic components such as ICs are mounted on the substrate back surface 332 opposite to the substrate surface 330, and no wiring pattern is formed (see FIG. 8). Further, the substrate back surface 332 is not provided with electrodes or the like for soldering terminals of electronic components mounted on the substrate surface 330 through through holes. That is, various electronic components are not mounted on the substrate back surface 332, and an input unit for receiving electrical input and an output unit (for example, a wiring pattern or a terminal) for output are provided. Absent.

  Here, with reference to FIG. 13 and FIG. 14, the non-mounting area | region in which the electronic component, wiring pattern, etc. in the security board 325 are not mounted is demonstrated.

  FIG. 13 is a diagram for explaining an unmounted region on the substrate surface 330 of the security substrate 325 according to the present embodiment. FIG. 14 is a diagram for explaining an unmounted region on the substrate back surface 332 of the security substrate 325 according to the present embodiment.

  Referring to FIG. 13, on the outer periphery of substrate surface 330, an unmounted region 330a (hatched portion in FIG. 13) in which electronic components and wiring patterns are not mounted is provided. Referring to FIG. 14, the entire surface of substrate back surface 332 is an unmounted region (hatched portion in FIG. 14). That is, when the security board 325 is connected to the CU control board 327 (see FIG. 15), the unmounted region 330a is configured so that electrical input and output cannot be easily performed from the side surface side of the board.

  Next, a connection configuration between the security board 325 and the CU control board 327 will be described. FIG. 15 is a diagram for explaining a connection configuration between the security board 325 and the CU control board 327. Referring to FIG. 15, security board 325 and CU control board 327 are connected such that board surface 330 of security board 325 faces CU control board 327. Specifically, the CU control board 327 is provided with a receptacle-side connector 500 which is a connection member of the header-side connector 510 provided on the board surface 330. Further, the CU control board 327 is provided with a protrusion 380 formed so as to be engaged with the openings 360 a and 360 b provided in the security board 325. The connector 500 and the connector 510 are connected, and the projection 380 is engaged with the openings 360a and 360b, whereby the security board 325 and the CU control board 327 are connected. Therefore, the connectors 500 and 510, the openings 360a and 360b, and the protrusions 380 function as connection members for connecting the security board 325 and the CU control board 327.

  16 and 17 are diagrams for explaining in detail the engagement between the opening 360a of the security board 325 and the protrusion 380 of the CU control board 327. FIG. Referring to FIG. 16, protrusion 380 has a base portion 380a and a tip portion 380b protruding from base portion 380a. The security board 325 is fixed to the CU control board 327 by inserting the distal end portion 380b into the 360a. The protrusion 380 may be formed of a cylindrical boss as shown in FIG. In this case, the opening 360 a is configured as a screw hole, and the security board 325 is fixed to the CU control board 327 by screwing the screw 382 through the boss. The engagement between the opening 360b of the security board 325 and the protrusion 380 of the CU control board 327 is the same as the engagement between the opening 360a and the protrusion 380.

  By connecting the security board 325 and the CU control board 327 in this manner, the board surface 330 on which the connector 510, the communication control IC 325a, the security chip 325b, and the like are mounted is not exposed to the outside. Further, there are no electronic components or electrical input portions on the substrate back surface 332 exposed to the outside. From this, it is possible to prevent the substrate surface 330 from being visually recognized from the outside. Further, it is possible to more effectively prevent unauthorized parts from being attached to the security board 325 and unauthorized input without removing the security board 325 from the CU control board 327. Furthermore, since the outer periphery of the substrate surface 330 is an unmounted region 330a in which no electronic components or electrical input portions exist, unauthorized input to the substrate surface 330 from the front side, the back side, and the left and right side surfaces is prevented. can do.

The entire substrate rear surface 432 is an unmounted region (hatched portion in FIG. 26).

  The security board 425 and the CU control board 327 are connected so that the board surface 330 of the security board 425 faces the CU control board 327. In addition, since the openings 360a and 360b do not exist in the security board 425, the security board 425 and the CU control board 327 are connected to each other by a connector 500 and a connector 510 that the security board 425 and the CU control board 327 have. In this case, the security board 425 is fixed to the CU control board 327 only by connecting the connector 500 and the connector 510. However, the CU control board 327 may be provided with a spacer or the like for supporting the security board 425.

  By connecting the security board 425 and the CU control board 327 in this manner, the board surface 430 on which the connector 510, the communication control IC 325a, the security chip 325b, and the like are mounted is not exposed to the outside. Attachment of unauthorized parts to the substrate 425 and unauthorized input can be more effectively prevented. Further, unauthorized input to the substrate surface 430 from the front side, the back side, and the left and right side surfaces can be prevented.

(Modification 2)
Next, Modification 2 of the security board 325 will be described. FIG. 27 is a perspective view of a security board 525 according to the second modification of the present embodiment. FIG. 28 is a plan view of a security board 525 according to the second modification of the present embodiment. FIG. 29 is a bottom view of a security board 525 according to the second modification of the present embodiment.

FIG. 32 is a front view of a security board 525 according to the second modification of the present embodiment. FIG. 33 is a rear view of the security board 525 according to the second modification of the present embodiment. In the security board 525 shown in FIG. 27 to FIG. 33, the external characteristic part is drawn with a solid line, and the non-characteristic part is drawn with a broken line.

  The security board 525 is different in that an opening 560 is provided instead of the openings 360a and 360b in the security board 325. The rest of the configuration is basically the same as that of the security board 325.

  FIG. 34 is a diagram for explaining an unmounted region on the substrate surface 530 of the security substrate 525 according to the second modification of the present embodiment. FIG. 35 is a diagram for explaining an unmounted region on the substrate rear surface 532 of the security substrate 525 according to the second modification of the present embodiment. The substrate surface 530 is provided with an unmounted region (hatched portion in FIG. 34) where no electronic component or wiring pattern is mounted. The entire rear surface of the substrate 532 is an unmounted region (hatched portion in FIG. 35).

  The security board 525 and the CU control board 327 are connected so that the board surface 530 of the security board 525 faces the CU control board 327. The security substrate 525 is provided with a horizontally long elliptical opening 560 that penetrates the substrate surface 530 and the substrate back surface 532. Therefore, a protrusion (not shown) that engages with the opening 560 is formed on the CU control board 327. Then, the connector 500 and the connector 510 are connected, and the protrusion of the CU control board 327 is engaged with the opening 560, whereby the security board 525 and the CU control board 327 are connected. In this case, since the protrusion of the CU control board 327 is composed of a horizontally long elliptical protrusion, fraud from the front side of the security board 325 can be more effectively prevented.

  By connecting the security board 525 and the CU control board 327 in this manner, the board surface 530 on which the connector 510, the communication control IC 325a, the security chip 325b, and the like are mounted is not exposed to the outside. Attachment of unauthorized parts to the substrate 525 and unauthorized input can be more effectively prevented. Furthermore, unauthorized input to the substrate surface 530 from the front side, back side, and left and right side surfaces can be prevented.

<Notification processing for abnormalities occurring in card units and pachinko machines>
FIG. 36 is an explanatory diagram for explaining notification processing when an abnormality is detected as a result of mutual authentication.

  Referring to FIG. 36, when an abnormality occurs in CU control unit 323, security board 325, payout control unit 171, or main control board 16, a notification is given in the direction indicated by the arrow in FIG. For the abnormality mentioned here, the CU control unit 323, the security board 325, the payout control unit 171, or the main control board 16 is replaced with another illegally manufactured one, or malfunction or failure occurs due to noise or the like. Or offline status due to disconnection or the like. The key management server 800 shown in FIG. 36 is a key management server that stores the SID and authentication key of the CU communication control unit in association with each serial ID (also referred to as SID) of the electronic component inside the CU 3. is there. The key management server 800 is a server that can communicate with the main control board 16.

  First, when an abnormality occurs in the security board 325 of the CU 3, the CU control part 323 detects the abnormality as a result of the mutual authentication performed between the CU control part 323 and the security board 325 described above. This mutual authentication includes device authentication using a session key in addition to serial ID authentication and device authentication described later.

  The serial ID is a serial ID (substrate serial ID) of the security board 325, and is stored in the ROM of the security chip 325b when the security chip 325b of the security board 325 is manufactured. Further, when the CU 3 is brought into the amusement hall and connected to the hall server 801, the board serial ID is downloaded from the key management server 800 of the key management center via the hall server 801 and stored in the CU control unit 323. The

  When the CU control unit 323 detects an abnormality in the security board 325, the CU control unit 323 notifies the hall server 801 to that effect and transmits an abnormality notification command to the display control unit 350 of the CU3. The CU control unit 323 controls the display 312 to display that an abnormality has occurred and causes the display control unit 350 to perform an abnormality notification by lighting or blinking an abnormality notification lamp (not shown). Further, the CU control unit 323 transmits a signal indicating that an abnormality has occurred from the external communication unit to the hall management computer.

  When an abnormality occurs in the CU control unit 323 of the CU 3, the security board 325 detects the occurrence of the abnormality by the above-described mutual authentication, and notifies the payout control unit 171 of a signal indicating that (an abnormality notification signal). The security board 325 notifies the payout control unit 171 of a signal via the PIF circuit 326. In response, the payout control unit 171 notifies the main control board 16 that an abnormality has occurred. As described above, the main control board 16 performs control to operate the abnormality notification lamp and transmits a signal indicating that an abnormality has occurred to the hall management computer.

  When the security board 325 detects an abnormality of the payout control unit 171, the CU control unit 323 is notified of this, and the CU control unit 323 notifies the hall server 801 accordingly.

  As described above, when the security board 325 detects an abnormality in the CU control unit 323, the security board 325 notifies the payout control unit 171 via the PIF circuit 326. On the other hand, when the security board 325 detects an abnormality in the payout control unit 171, To the CU control unit 323, and the notification destination of the occurrence of abnormality by the security board 325 is different. The reason for this is that even if the control unit in which an abnormality has occurred is notified that an abnormality has occurred, no abnormality notification control is performed and no abnormality prevention measure is provided. In addition, the security board 325 has a communication control function but does not have an abnormality notification control function. Therefore, the abnormality notification cannot be controlled by itself, and for this reason, notification is made that an abnormality has occurred in the direction of the control unit opposite to the control unit where the abnormality has occurred. The payout control unit 171 that has received the notification of the occurrence of the abnormality from the security board 325 via the PIF circuit 326 notifies the main control board 16 accordingly. Upon receiving the notification, the main control board 16 performs the same control for abnormality notification as described above.

  When an abnormality occurs in the payout control unit 171, the security board 325 detects that fact and notifies the CU control unit 323 that the abnormality has occurred. The CU control unit 323 performs the above-described abnormality notification control. The hall server 801 is notified that an abnormality has occurred. When an abnormality occurs in the payout control unit 171, it is detected that an abnormality has occurred in the main control board 16, and upon receiving the notification, the above-described abnormality notification control is performed.

  As described above, the payout control board 17 detects and notifies the abnormality to the main control board 16 when an abnormality occurs in the security board 325, while notifies the abnormality to the main control board 16. It detects and notifies the security board 325 that an abnormality has occurred. As with the security board 325 described above, the payout control board 17 is also controlled for anomaly notification even when a notice is given to the control unit in which an abnormality has occurred when it is detected that an abnormality has occurred. Therefore, a notification is sent to the control unit or control board on the opposite side of the control unit where the abnormality has occurred. The security board 325 and the payout control board 17 are not connected to an abnormality notification means such as an abnormality notification lamp or an abnormality notification display, and have a function of performing abnormality notification control themselves even when an abnormality is detected. Absent. In the above description, the security board 325 and the payout control board 17 are not connected to an abnormality notification means such as an abnormality notification lamp or an abnormality notification display, and perform abnormality notification control themselves even when an abnormality is detected. Although described as having no function, the security board 325 and the payout control board 17 may be provided with an abnormality notification function to directly notify that an abnormality has occurred.

<Transmission / reception mode between card unit side and pachinko machine side>
Next, FIG. 37 is a schematic diagram showing main data among various data stored on each of the CU 3 side and the P base 2 side and its transmission / reception mode. With reference to FIG. 37, main data among various data stored on each of the CU (card unit) 3 side and the P unit (pachinko gaming machine) 2 side and its transmission / reception mode will be described.

  In the present embodiment, the fluctuation of the number of game balls is calculated on the P stand 2 side, and the current latest game ball number is stored and managed. The current number of game balls is also calculated and stored on the CU 3 side, but the number of game balls is based on information transmitted from the P stand 2 side. On the other hand, the CU3 side manages and stores the number of possessed balls (the number of cards possessed), the number of stored balls, and the remaining card amount (remaining amount).

  FIG. 37 shows RAM storage data provided in the CU control unit 323 on the CU3 side and RAM storage data mounted on the payout control board 17 on the P table 2 side. First, when the power supply is turned on for the first time when the P unit (pachinko gaming machine) 2 and the CU (card unit) 3 are electrically connected after being installed in the game hall, the payout control board on the P unit 2 side 17 has a main chip ID (main control chip ID) transmitted from the main control board 16, transmits the main chip ID to the CU3 side, and also issues a payout chip ID (payout) stored in the payout control board 17 itself. Control chip ID) is transmitted to the CU3 side.

  On the CU3 side, the transmitted main chip ID and payout chip ID are stored. Next, data of the connection time, that is, the time at which communication is started after the CU 3 side and the P base 2 side are connected is transmitted from the CU 3 side to the P base 2 side, and the transmitted connection time is transmitted on the P base 2 side. Remember.

  In this state, three pieces of information of the main chip ID, the payout chip ID, and the connection time identified on the CU3 side are stored on the CU3 side and the P stand 2 side. When the power is turned on thereafter, the three pieces of information, that is, the main chip ID, the payout chip ID, and the previous connection time data are transmitted from the P stand 2 side to the CU 3 side.

  On the CU 3 side, the transmitted data is collated with the data already stored, and it is determined whether or not the same P base 2 is connected as in the previous time. As for the connection time data, every time the power is turned on, new connection time data in which communication between the CU 3 side and the P base 2 side is started is transmitted from the CU 3 side to the P base 2 side. Time data is stored on the P table 2 side.

  Both the CU and the P platform transmit the “sequential number” added to the message. Further, both the CU and the P platform store the “serial number” received from the other party. There are three types of “serial number”: “normal serial number”, “additional serial number”, and “counting serial number”. “Normal sequence number” indicates the sequence number of the message. “Normal serial number” is transmitted by counting up (+1) the serial number received at the time of transmission on the CU3 side (primary station side) with an initial value “1”. However, the “normal serial number” is not counted up at the time of retransmission. P station 2 side (secondary station side) transmits the received serial number as it is. Note that there is no response if the serial number continuity is not established. The “additional serial number” is a serial number used when the CU 3 requests the P unit 2 to add game balls. The “counting serial number” is a serial number used when the P stand 2 requests the CU 3 to count game balls.

  Only the CU3 has the right to update the normal serial number. When the normal serial number that is the same as the transmitted normal serial number is returned, the CU 3 backs up and stores the normal serial number and transmits the updated normal serial number. Only the CU3 has the addition update right of the addition serial number. When the addition request is made, the CU 3 transmits an addition sequence number added to the addition sequence number that has been used for communication until then to the P unit 2. The P platform 2 returns the same addition serial number when accepting the request. When rejecting the request, the previously received addition sequence number (the addition sequence number received this time-1) is returned. Only the P-unit 2 has the counting update number addition update right. When making a request for counting, the P platform 2 transmits to the CU 3 a counting sequence number that is +1 to the counting sequence number that has been used for communication. When CU3 accepts the request, it returns the same counting sequence number. When rejecting the request, the received counting sequence number (counting sequence number-1 received this time) is returned.

  In the following, with regard to “normal serial number”, a configuration will be described in which the serial number received by the CU 3 at the time of transmission is counted up (+1) and transmitted. However, the present invention is not limited to this configuration. Each of the P base 2 and the CU 3 or the serial number received by the P base 2 at the time of transmission is counted up (+1), and the other is the received serial number. May be transmitted as it is.

  The “addition serial number” and “counting serial number” are special serial numbers that are counted up in the addition request processing and the count request processing, respectively. Hereinafter, a description will be given of a configuration in which “normal serial number” is also counted up when the “additional serial number” and “counting serial number” are counted up. However, the present invention is not limited to this configuration, and may be configured to stop the “normal sequence number” from being counted up when the “additional sequence number” and the “counting sequence number” are counted up. In the following, “normal serial number” is simply referred to as “serial number”. The “additional sequence number” and “counting sequence number” are also collectively referred to as “request sequence number”.

  The latest game machine information (game machine information being counted) is transmitted from the P machine 2 side to the CU 3 side. This latest game table information is stored in the latest game table information storage area of the RAM of the payout control unit 171 (see FIG. 4) on the P table 2 side. Specifically, information on the added ball number counter, information on the subtracted ball number counter, and information on the counted ball number counter are included. The number of game balls is not included in the latest game table information, and is transmitted from the P table 2 side to the CU 3 side as the count value of the game ball number counter as will be described later. However, instead of this, or in addition to the game ball counter, the number of game balls may be included in the latest game table information.

  Information on these counters is collectively transmitted to the CU side as a response. The added ball number counter is a counter that counts the added ball number. The added ball is the sum of “the number of winning balls × the number of winning balls” and “the number of back balls”. The back ball is a foul ball. That is, the addition ball indicates the number that the addition ball counter should add to the game ball. The subtraction ball number counter is a counter that counts the number of subtraction balls. The subtraction ball is the “number of fired balls”. That is, the number of balls detected by the output change from on to off of the ball raising switch (upper) 41a. Note that the “number of balls to be subtracted” does not include the “number of balls to be counted”. The counting ball counter is a counter that counts the counting balls. The counting ball is “the number of balls converted from game balls to holding balls by the counting operation”. Here, the “prize ball” is a ball that is paid out when a ball wins a winning opening, and is a safe ball. The “fired ball” is a ball fired by the gaming machine. When there is a back ball, the number of balls obtained by subtracting the back ball is the number of fired balls. The “back ball” is a ball in which the fired ball returns without jumping onto the board surface. The “out mouth passing ball” is a ball that has passed through the out mouth 154, and the total number of balls of the out ball and the safe ball means the number of balls passing through the out mouth.

  For example, when a pachinko ball that has been placed in the game area 27 wins and the winning information is transmitted from the main control board 16 to the payout control board 17, an additional ball to which a gaming ball is added based on the winning information. The added ball number counter counts the number, and the value of the added ball number counter (added ball number) is transmitted from the P stand 2 side to the CU 3 side. Also, the subtraction ball counter counts the number of shot balls as the number of subtraction balls based on the output change from on to off of the ball raising switch (upper) 41a due to the pachinko ball being shot in the game area 27, The value of the subtraction ball number counter (subtraction ball number) is transmitted from the P stand 2 side to the CU3 side.

  Alternatively, the payout control unit 171 counts the number of gaming balls as the number of counting balls by pressing the counting button 28, and transmits the value of the counting ball number counter (counting number of balls) from the P stand 2 side to the CU3 side.

  On the P-unit 2 side, each time the values of the addition ball counter, the subtraction ball counter, and the counting ball counter are transmitted to the CU 3 side, the count values are stored in the previous gaming machine information storage area (the RAM of the payout control unit 171) Etc.) are stored (rewritten) as backup data, and the values of the added ball counter, subtracted ball counter, and counted ball counter as the latest game table information are cleared to 0 (excluding the game ball counter). In the present embodiment, “clear” has the same meaning as “initialization”.

  As a result, the game table information transmitted to the CU 3 side immediately before is added to the storage area of the previous game table information (game table information transmitted immediately before). Stored as data. When the latest game machine information is not transmitted from the P machine 2 side to the CU 3 side, the backup data includes not only the value of each counter at the time of the next transmission but also the value of each counter of the previous time that was not transmitted. It is intended to enable transmission. You may make it memorize | store by adding the number of game balls transmitted immediately before to this last game machine information.

  Further, the payout control board 17 updates the value of the game ball counter in response to the occurrence of a prize, the firing of a ball, the occurrence of a back ball, and the occurrence of a counting ball (conversion from a game ball to a holding ball), The updated value of the game ball counter is transmitted to the CU 3 side as the number of game balls.

  On the CU3 side, the number of game balls, the number of cards held (simply referred to as the number of balls), the number of balls stored, the remaining amount, the total number of added balls (total number of added balls), total subtraction are stored in the cumulative data storage area in the RAM. The number of balls (the total number of subtracted balls) and the number of balls at the time of card insertion are stored. The number of cards possessed is the number of balls obtained by subtracting the number of possessed balls paid out (the number of balls converted from the number of cards possessed to the number of game balls) from the number of balls possessed when the card is inserted, and adding the counted number of balls. That is, the card possession number is the number of possession possessed by the player at the present time.

  The total number of added balls is added based on the value (number of added balls) of the added ball counter transmitted from the P stand 2 side to update the number of balls. Further, the number of balls is updated by subtracting the total number of subtraction balls based on the value of the subtraction ball counter (the number of subtraction balls) transmitted from the P stand 2 side. Further, based on the value of the counting ball number counter transmitted from the P stand 2, the number of card holding balls is added and updated. In this way, the CU 3 can manage the latest information by updating the total added ball number, the total subtracted ball number, and the card holding ball number with the latest game table information transmitted from the P table 2 one by one. It becomes possible.

  As shown in the figure, the CU 3 has an area for storing game balls, and also receives a count value of a game ball number counter (also referred to as game ball number or game ball total number information) from the P stand 2 side. CU3 updates the area for storing game balls in the following procedure. That is, the CU 3 stores the value based on the value of the added ball number counter (added ball number), the value of the subtracted ball number counter (subtracted ball number), and the value of the counted ball number counter transmitted from the P side. The number of game balls being updated is updated, and it is determined whether or not the count value of the game ball counter transmitted from the P platform side at the same timing matches the updated number of game balls. If they match, the game is allowed to continue, but if they do not match, control to shift to an error state is performed.

  As a result, for example, an error notification lamp or indicator 312 is used to notify an error, or an error notification signal indicating that an error has occurred is transmitted to the hall management computer or hall server 801 (in this case, hall management). An error notification may be performed by a computer or hall server 801). As a result, a predetermined notification that prompts an artificial response by a staff member is performed.

  Instead of shifting to an error state and stopping the game, the number of game balls stored on the CU 3 side may be replaced with the count value of the game ball counter transmitted from the P unit 2 side. Good. Alternatively, it may be corrected to an average value of the number of game balls managed on the CU 3 side and the number of game balls stored on the P stand 2 side.

  As described above, in this embodiment, the number of game balls is also stored on the CU 3 side, but it is determined whether or not the number of game balls matches the number of game balls managed and stored on the P-unit 2 side. (CU3 side function). Therefore, even if a situation occurs in which the number of game balls stored on the P stand 2 side does not match the number of game balls stored on the CU 3 side due to fraud or other circumstances, it can be checked. Here, the determination function is provided on the CU3 side. For example, the number of game balls stored on the CU3 side and the Pball 2 side are stored by the hall server 801 or the hall management computer connected to the CU3. The number of game balls being played may be received, and it may be determined whether or not the two match.

  As shown in FIG. 37, the CU 3 stores a storage area for storing the number of cards held and the number of stored balls, a storage area for storing the remaining card amount of the received (inserted) card, and the total number of additional balls (the number of additional balls). (Cumulative total), the total number of subtracted balls (total number of subtracted balls), and a storage area for storing balls when the card is inserted. The CU control unit 323 (see FIG. 4) stores a stored ball in response to an input requesting the use of the stored ball (for example, a press input of the replay button 319 provided on the CU 3 (when there is no holding ball)). Subtract a certain number of balls from the area.

  The CU control unit 323 (see FIG. 4) is an input requesting the use of the holding ball (for example, pressing input of the replay button 319 provided on the CU 3 when the holding ball is present (however, when the holding ball is present)) Accordingly, a predetermined number of balls are subtracted from the storage area for storing balls. Furthermore, the CU control unit 323 (see FIG. 4) subtracts a predetermined value from a storage area for storing the card remaining amount in response to an input requesting use of the card remaining amount (for example, pressing input of the ball lending button 321).

  When a player performs an operation to deduct the value from the player's own gaming value (for example, the prepaid balance, the number of balls, or the number of balls) and use it for the game, the number of balls that are deducted is the number of balls The number of balls to be added to the counter is transmitted from the CU 3 side to the P stand 2 side. In response to this, the P stand 2 side adds and updates the game ball counter.

  In the gaming system according to the present embodiment, on the other hand, it is possible to accept a so-called wagon service order in which the gaming value owned by the player is withdrawn and exchanged for a drink or the like. However, access to wagon services with game balls is restricted, and wagon services can only be received with holding balls. This is an image that prohibits the use of the ball before counting remaining in the dish by hand and using it for the wagon service in the conventional enclosed circulation pachinko gaming machine provided with each counter.

  For this reason, in this embodiment, when the operation for performing the wagon service is executed, if the number of balls is less than the number corresponding to the desired menu of the wagon service, the player is prompted to perform the counting operation. Has been. When the player performs a counting operation at that time, the number of counting balls based on the operation is transmitted from the P stand 2 side to the CU 3 side. In response to this, the CU3 side subtracts the number of game balls and adds and updates the number of card possessions.

<Frame configuration used in communication>
Next, communication between the CU 3 and the P base 2 according to the present embodiment will be described in more detail. A message used in the communication is composed of a frame having a predetermined format. Transmission data (message) is always transmitted in units of one frame. That is, the divided transmission of the message is not performed. Moreover, when transmitting a message | telegram continuously, the space | interval of 1 millisecond or more is opened.

  One frame of transmission data includes a data length, a normal sequence number, an addition sequence number, a counting sequence number, a command, and a data portion. “Data length” indicates the data length of the transmission data (serial number to data portion (business message range)). “Command” is a command code of the message. The “data part” is data of a message.

<Main sequence in communication between CU and P platform>
<< Send command and response >>
First, transmission of commands and responses between the CU 3 and the P base 2 will be described. A command is transmitted from CU3 (primary station) to P station 2 (secondary station), and P station 2 returns a response to CU3 in response to the command. In other words, the business message transmission is a command / response system in which the CU 3 is the primary station and the P stand 2 is the secondary station.

  The period from the transmission of the first command to the P unit 2 from the CU 3 to the transmission of the next command is controlled to 200 ms, that is, 0.2 seconds. Further, the period from the transmission of the response from the P base 2 to the CU 3 until the transmission of the next response is controlled to 200 ms, that is, 0.2 seconds.

  Thus, both a command and a response are transmitted between the CU 3 and the P base 2 at an interval of 200 ms. On the other hand, by operating the hitting operation handle 25, the P platform 2 hits 100 pachinko balls into the game area 27 per minute, so the hitting time interval is 0.6 seconds. As a result, a plurality of commands and responses are transmitted and received while firing one ball.

  Therefore, responses for notifying the amount of change in the number of game balls are sequentially transmitted from the P platform 2 to the CU 3 at intervals shorter than the ball firing time interval. As a result, the P stand 2 can finely notify the CU 3 of the amount of change in the number of game balls.

  Here, the transmission interval of the command and the response is set to 200 ms, but the transmission interval may be longer or shorter than this. For example, the transmission interval may be a firing time interval of the P platform 2. It is also possible to match with

<< Communication line disconnection detection on CU side >>
Next, processing when communication disconnection is detected on the CU3 side will be described. When the response is not received within 200 ms after the CU 3 transmits a command to the P unit 2, the same command is transmitted to the P unit 2 again. Further, if a response cannot be received within 200 ms, a second retransmission is performed in which the same command is transmitted to the P unit 2. Resend the same command to P-unit 2 up to 14 times. If the response is not received from the P-unit 2 even after the 14th retransmission, the CU 3 determines that the communication is abnormal after 3 seconds and sets “communication interruption”. This communication abnormality may be caused when the connector of the CU 3 and the connector of the P base 2 are disconnected, or the connection wiring is disconnected or the power supply of the P base 2 is disconnected. CU3 does not increment the serial number when retransmitting the command.

<< Communication line disconnection detection on P side >>
Processing when communication disconnection is detected on the P platform 2 side will be described. A command is transmitted from the CU 3 to the P unit 2, and the P unit 2 returns a response to the CU 3 in response to the command. Thereafter, when the state in which the command from the CU 3 is not transmitted to the P stand 2 continues for 3 seconds, the P stand 2 determines that the communication is cut off, stops the driving of the firing motor 18 and stops the game. The cause of this communication disconnection may be the disconnection of the connector of CU3 and the connector of P base 2, disconnection of connection wiring, or power supply disconnection of CU3.

  It should be noted that the command and response for detecting communication disconnection on the P platform 2 side include recovery request / recovery response, recovery request 2 / recovery response 2, communication start request / communication start response, notification end request / communication end response, and communication Does not include test request / communication test response command and response.

<Encryption key used for communication between key management server and communication control IC>
Next, an encryption key used for communication between the key management server and the communication control IC will be described. FIG. 38 is a diagram for explaining an encryption key used for communication from the key management server to the communication control IC 325a. First, encryption keys used for communication between the key management server and the communication control IC 325a mainly include a board shipment key, a board initial key, a board authentication key, a main authentication key, a temporary authentication key, and an effective key (commercial). , Communication key 1 (session key) and communication key 2 (session key). The board shipment key is used for communication between the CU control unit and the SC, and is used only for encryption of a communication test message before shipment. The board initial key is used for communication between the CU control unit and the SC, and is received by the CU control unit 323 during the initial communication with the hall server, and stored in the RAM of the CU control unit 323. The SC 325b generates a substrate initial key from the embedded information at the time of manufacture and stores it in the RAM. Authentication communication (substrate initial key mode) using the substrate initial key is permitted (timed operation) only for a limited period. Here, in the board initial key mode, as described above, it is necessary to communicate normally with the hall server at least once to acquire the board initial key, and thus security is ensured.

  Here, the “limited period” is a limited period of two days, for example. In this way, by enabling timed operation, even if the key cannot be exchanged with the key management server immediately after the system is installed in the hall, the hall will start operating immediately after the system is installed. It becomes possible. In addition, as a limited period, you may set the period defined in one day, for example to every morning from 9:00 to 17:00.

  The above-described board initial key mode has a restriction that enables authentication communication using the board initial key for a limited period of time, but the present invention is not limited to this, and the amount of money that can be used ( Card balance or cash) may be limited. Alternatively, when the number of symbol variations in the variable display device reaches a certain number, the game may be forcibly terminated and the gaming machine may be controlled to be disabled. Alternatively, when the cumulative number of jackpots reaches a certain number, the game may be forcibly terminated and the gaming machine may be controlled to be disabled. In addition, it may be possible to allow only a game by inserting cash and prevent a game using the remaining card amount, or to limit the game to a game using a holding ball.

  The board authentication key is an encryption key that is used for communication between the CU control unit and the SC and is received as part of the board security information from the key management server. By performing authentication communication using the board authentication key, the communication mode (board authentication key mode) is switched from the timed operation using the board initial key to the permanent operation (normal operation). This board authentication key is stored in the RAM of the CU control unit and the RAM of the SC.

  In both the timed operation using the board initial key and the permanent operation using the board authentication key, the CU control unit 323 receives the valid key stored in the hall server, and the SC 325b receives the valid key as the communication control IC 325a. This is realized by enabling communication between the P platform and the CU.

  This authentication key is used for communication between the SC and the communication control IC, is generated by the SC 325b from the update information received from the key management server, and is stored in the RAM of the SC 325b. The communication control IC 325a is also similar to the SC 325b. Are generated from the update information and stored in the RAM of the communication control IC 325a. Note that this authentication key may be acquired from a key management server or the like. Further, the CU control unit 323 and the communication control IC 325a may generate themselves without receiving update information from a key management server or the like. In addition, the CU control unit 323 and the communication control IC 325a themselves generate predetermined second data by acquiring predetermined first data from a key management server or the like, and this authentication key is obtained from the first data and the second data. You may make it produce | generate.

  The temporary authentication key is used for communication between the SC and the communication control IC, and until the authentication key is generated (or until a set allowable time (for example, two days) elapses), the SC 325b and Used for encryption communication with the communication control IC 325a. The encrypted communication using the temporary authentication key (temporary authentication key mode) is allowed (timed operation) only for a limited period (for example, 2 days). SC 325b and communication control IC 325a store temporary authentication keys in their respective ROMs from the manufacturing stage. The valid key (commercial) is a key that is received by the SC 325b via the CU control unit 323 and transmitted (set) to the communication control IC 325a during initial communication with the hall server. Communication with P devices becomes possible by setting the effective key. The valid key is data for activating the communication control IC 325a. In other words, the valid key is permission information for permitting communication between the CU and the P platform.

  The communication key 1 (session key) is used for communication between the CU control unit and the SC, is used for business message communication for gaming machines, and is created every business day by the SC 325b using some variable. For example, a counter value (random number) or date / time information may be used as the variable. The communication key 2 (session key) is used for communication between the SC and the communication control IC, and is used for business message communication for gaming machines.

  Note that even if the key described above has a configuration in which the key data is embedded in each part as it is, the information for generating the key data is stored in each part. The key data may be generated by using the key.

  Next, a method for acquiring an encryption key and a method for performing encrypted communication using the acquired encryption key will be described. First, the SC 325b acquires an effective key via the CU control unit 323 at the first communication with the hall server. The SC 325b transmits (sets) the acquired effective key to the communication control IC 325a, thereby enabling communication with the P units. The CU control unit 323 receives the board initial key at the first communication with the hall server, and stores it in the RAM of the CU control unit 323. The SC 325b generates a substrate initial key from the embedded information at the time of manufacture and stores it in the RAM. The SC 325b performs cryptographic authentication with the CU control unit 323 using the acquired substrate initial key, and performs cryptographic communication with the CU control unit 323 in a timely manner using the substrate initial key. In addition, the hall server that has received the connection request sent from the CU control unit 323 when the power is turned on returns a unified store code for identifying the game arcade where the hall server is installed to the CU control unit 323. Specifically, the unified store code is transmitted from the input / output interface of the hall server to the CU control unit 323 according to the control of the CPU of the hall server.

  On the other hand, authentication is performed between the CU control unit 323 and the SC 325b using the board manufacturer code stored as initial information in both. The board manufacturer code is a code that identifies the manufacturer that manufactured the security board 325. A board connection request and a board connection response are exchanged on the condition that the authentication using the board manufacturer code is successful (see FIG. 44). The unified store code is included in the board connection request transmitted from the CU control unit 323 to the SC 325b, and the SC 325b acquires the unified store code by receiving the board connection request.

  Next, the CU control unit 323 requests the board security information from the key management server and receives the board security information transmitted from the key management server via the hall server, so that the board security information is included in the board security information. Get the board authentication key. The CU control unit performs cryptographic authentication with the SC using the acquired board authentication key, and performs cryptographic communication with the SC using the board authentication key. Note that the CU control unit 323 does not change the key from the board initial key to the board authentication key immediately after obtaining the board authentication key, but on condition that the gaming machine is in a non-operating state as described later. Change the key.

  The board authentication key may be generated by the CU control unit 323 itself instead of being acquired from the key management server or the like, and the CU control unit 323 itself acquires predetermined first data from the key management server or the like. Predetermined second data may be generated, and a board authentication key may be generated from the first data and the second data.

  Next, SC 325b performs cryptographic communication with communication control IC 325a using the stored temporary authentication key. Then, the SC decrypts the update information acquired from the key management server by performing cryptographic communication with the CU control unit using the board authentication key, and inquires about the board inquiry number. If the inquiry board inquiry number matches, the SC generates a main authentication key from the update information and performs cryptographic communication with the communication control IC 325a using the generated main authentication key. The authentication key is not stored in the communication control IC 325a from the time of shipment, and is generated from the update information in the same manner as the SC 325b.

  Next, the SC notifies the CU control unit of the communication key 1 and performs communication with the CU control unit using the communication key 1 so that business message communication with the gaming machine is possible. It becomes. In addition, the SC sets an effective key for the communication control IC, thereby receiving a notification of the communication key 2 from the communication control IC and performing communication with the communication control IC thereafter using the communication key 2. As a result, business message communication with the gaming machine becomes possible.

<Main sequence in communication between CU control unit and SC>
Next, processing executed by the CPU in the CU control unit 323 and processing executed by the security chip (SC) 325b will be described with reference to FIGS.

  First, with reference to FIG. 41, the process of starting up the CU control unit 323 when the power is turned on and the hall is installed will be described. FIG. 41 shows a sequence when the power supply is first turned on after the CU 3 is installed in the game arcade, and in particular, a startup sequence at the time of hall installation using the board initial key will be described.

  First, when the power of the CU3 is turned on, the CU control unit 323 and the SC325b are activated. When the power is first turned on after CU3 is installed in the amusement hall, the CU control unit 323 receives the board initial key A from the host device (specifically, from the hall server), the MAC key of the board initial key A, the valid Acquire a key (for commercial / P shipment). Here, the board initial key A is an encryption key that is downloaded from the hall server and stored in the CU control unit 323 when first communicating with the host device after being delivered to the amusement hall, and is installed in the key management center. This is an encryption key used for communication between the CU control unit 323 and the SC 325b until the board information (board serial ID and board authentication key) stored in the key management server is acquired. The board initial key A is decrypted using the board manufacturer code, while the MAC key of the board initial key A is similarly decrypted using the board manufacturer code. Such decryption is performed by a decryption method conforming to the AES (Advanced Encryption Standard) encryption method.

  Thereafter, the CU control unit 323 and the SC 325b execute a board manufacturer code authentication sequence, a board initial key authentication sequence, and a security board information inquiry sequence.

  The board manufacturer code authentication sequence authenticates the board manufacturer code between the CU control unit 323 and the SC 325b using a challenge / response method. After processing the board manufacturer code authentication sequence, the CU control unit 323 and the SC 325b use the board initial key acquired from the hall server as the encryption key, perform the board initial key authentication sequence, and perform authentication when the board initial key authentication is completed. It becomes. Detailed processing of the board initial key authentication sequence will be described later.

  Thereafter, the CU control unit 323 and the SC 325b perform the security board information inquiry sequence using the board initial key obtained from the hall server as the encryption key, and the acquisition is OK when the security board information can be obtained. The security board information is acquired from the key management server of the key management center, and includes a board serial ID, a board authentication key, and the like. Details of the security board information inquiry sequence will be described later. The board authentication key is an encryption key that is downloaded from a key management server installed in the key management center and used for communication between the CU control unit 323 and the SC 325b. The key management server stores the board authentication key in association with the board serial number or the like.

  When the security board information can be acquired by the security board information inquiry sequence, the SC 325b performs authentication with the communication control IC 325a.

  Thereafter, the CU control unit 323 and the SC 325b use the board initial key acquired from the hall server as the encryption key, perform a communication key exchange sequence, and exchange a communication key for business message communication.

  Thereafter, the CU control unit 323 and the SC 325b use the substrate initial key as the encryption key, perform a communication key exchange sequence, and generate a communication key. In the communication key exchange sequence, the substrate authentication key is used as the encryption key when the substrate information can be acquired in the substrate information acquisition sequence. However, when the substrate information cannot be acquired, the substrate initial key is used as the encryption key for a limited time. Specifically, the communication key is generated using a random number and current time data. The method for generating this communication key (session key) is not limited to random number and current time data, but any variable data other than the key used for mutual authentication between encrypted communication devices can be used.

By performing business telegram communication with this gaming machine, gaming can be performed on the gaming machine. The business message communication with the gaming machine is operated using a communication key (session key). The communication at this time is time-limited communication as described above, and is allowed only for a certain period (for example, 2 days). The communication mode performed through the above processing is the restricted communication mode (substrate initial key mode (substrate initial key operation)). If a certain period (for example, 2 days) is exceeded in this timed operation, the temporary operation is stopped and the overage is notified from the SC 325b to the key management server via the CU control unit 323 and the hall server. The

  Thereafter, the CU control unit 323 and the SC 325b execute a board manufacturer code authentication sequence, a board authentication key authentication sequence, and a security board information inquiry sequence.

  The board manufacturer code authentication sequence authenticates the board manufacturer code between the CU control unit 323 and the SC 325b using a challenge / response method. After processing the board manufacturer code authentication sequence, the CU control unit 323 and the SC 325b perform the board authentication key authentication sequence using the board authentication key acquired from the key management server as the encryption key. Detailed processing of the board authentication key authentication sequence will be described later.

  Thereafter, the CU control unit 323 and the SC 325b perform the security board information inquiry sequence using the board authentication key acquired from the key management server as the encryption key only when the key is updated.

  The SC 325b executes authentication with the communication control IC 325a when the board authentication key can be authenticated by the board authentication key authentication sequence and there is no key update, or when there is a key update and authentication can be performed by the security board information inquiry sequence. .

  Thereafter, the CU control unit 323 and the SC 325b use the board authentication key as the encryption key, perform a communication key exchange sequence, and generate a communication key. Specifically, the communication key is generated using a random number and current time data. The method for generating this communication key (session key) is not limited to random number and current time data, but any variable data other than the key used for mutual authentication between encrypted communication devices can be used.

  Next, with reference to FIG. 43, a process of turning on the power of the CU control unit 323 and starting up at the time of factory shipment will be described. FIG. 43 shows a sequence at the time of factory shipment before the CU 3 is shipped to the amusement hall, and in particular, a factory shipment start-up sequence using the board shipment key will be described. This sequence is a process in the CU control unit 323 and the SC 325b that is not connected to the host device at the time of factory shipment.

  First, when the power of the CU3 is turned on, the CU control unit 323 and the SC325b are activated. The CU control unit 323 and the SC 325b execute a board manufacturer code authentication sequence and a board initial key authentication sequence.

  The board manufacturer code authentication sequence authenticates the board manufacturer code between the CU control unit 323 and the SC 325b using a challenge / response method. After processing the board manufacturer code authentication sequence, the CU control unit 323 and the SC 325b perform the board initial key authentication sequence using the board initial key as the encryption key. However, since the CU3 is not yet installed in the game arcade at the factory shipment stage, the CU control unit 323 cannot acquire the base initial key from the hall server of the game arcade, and as a result, the board initial key authentication is performed. The result is NG.

  After that, since the board initial key authentication sequence is authentication NG, the CU control section 323 sends a board shipment key request command to the SC 325b to request the board shipment key used for testing the security board 325. Send to. After receiving the board shipment key request command from the CU control unit 323, the SC 325b transmits a board shipment key response response including the board shipment key to the CU control unit 323.

  If the board shipping key can be authenticated by the board shipping key authentication sequence, the SC 325b performs authentication with the communication control IC 325a.

  Thereafter, the CU control unit 323 and the SC 325b use the board shipment key as the encryption key, perform a communication key exchange sequence, and generate a communication key. Specifically, the communication key is generated using a random number and current time data. The method for generating this communication key (session key) is not limited to random number and current time data, but any variable data other than the key used for mutual authentication between encrypted communication devices can be used. Also good. Note that the communication key exchange sequence is for exchanging a key (communication key) used for encryption communication with a gaming machine in order to enable gaming by the gaming machine, and detailed processing will be described later.

  When the communication key can be generated by the communication key exchange sequence, the SC 325b acquires the gaming machine chip information from the communication control IC 325a.

  Thereafter, the CU control unit 323 and the SC 325b use the communication key acquired from the communication key exchange sequence as the encryption key, perform a gaming machine chip information inquiry sequence, and inquire / notify gaming machine chip information. The gaming machine chip information includes a main control chip number and a payout control chip number. Detailed processing of the gaming machine chip information authentication sequence will be described later.

  Thereafter, the CU 3 makes a communication test request to the P unit 2, and the P unit 2 transmits a communication test response to the CU 3.

  By performing the above processing, the CU control unit 323 and the SC 325b can communicate with the gaming machine only by the communication test message. By performing communication of this communication test message, a communication test at the time of factory shipment is performed. CU3 that has passed the factory communication test is delivered to the amusement hall, and the first power-on sequence is the hall installation sequence described with reference to FIG. 41, and is executed after obtaining the board authentication key.

  Upon receiving the board manufacturer code authentication request 1 command, the SC 325b generates a challenge code based on the board manufacturer code, and notifies the CU control unit 323 of the generated challenge code as a response of the board manufacturer code authentication response 1.

  Upon receiving the board manufacturer code authentication response 1 command, the CU control unit 323 generates a response code based on the challenge code, and notifies the generated response code to the SC 325b using the board manufacturer code authentication request 2 command. Specifically, the response code is generated by encrypting the challenge code received using the board manufacturer code as a key.

  The SC 325b that has received the board manufacturer code authentication request 2 command checks the response code (specifically, if the challenge code is extracted by decrypting the response code using the board manufacturer code as a key), the challenge code matches. Assume that the check result is OK. Then, the check result is notified to the CU control unit 323 as a response of the board manufacturer code authentication response 2.

  The SC 325b that has received the security board inquiry instruction notification command notifies the CU control unit 323 of information (board serial number and inquiry information) for inquiring of the host device (specifically, the key management server via the hall server). A response of the security board inquiry result is returned to the CU control unit 323. Note that the response of the security board inquiry instruction notification to be returned is encrypted by using the board initial number or board authentication key as the board serial number as the encryption key, and the CU control unit 323 and the hall server cannot decrypt the key (hereinafter referred to as the key). The query information is encrypted with a “secret key”. As a result, the inquiry information can be decrypted and decrypted only by the key management server.

  Upon receiving the response of the security board inquiry result, the CU control unit 323 receives the information (the board serial number and the board serial number and the security management board 325) from the host device (specifically, the key management server via the hall server) based on the board serial number and the inquiry information. Query information) and wait for a response from the host device. While inquiring about security board information, the CU control unit 323 and the SC 325b do not wait for a response from the host device, and process the next step (for example, communication control IC authentication processing, gaming machine chip information authentication processing, gaming machine Business message processing, etc.), and necessary processing is performed when security board information is received.

  Thereafter, when receiving the inquiry result of the security board information (board serial ID and board authentication key) from the host device, the CU control unit 323 notifies the security board information to the SC 325b.

Note that the gaming machine chip inquiry instruction notification command to be transmitted is encrypted using a communication key as an encryption key.

  On the other hand, the SC 325b acquires the gaming machine chip information from the communication control IC, and then the SC 325b that has received the gaming machine chip inquiry instruction notification command inquires of the host device (specifically, the key management server via the hall server). In order to notify the CU control unit 323 of information (main control chip information and payout control chip information), a response of the gaming machine chip inquiry result (authentication OK) is returned to the CU control unit 323. Note that the response of the game machine chip inquiry instruction notification to be returned is encrypted with the main control chip ID and the payout control chip ID using a secret key, and the other information is encrypted using a communication key as an encryption key.

  The CU control unit 323 that has received the response of the gaming machine chip inquiry result sends the gaming machine chip information (mainly the main management chip information and the payout control chip information) to the host device (specifically, the key management server via the hall server). Control chip information and payout control chip information) and wait for a response from the host device. While inquiring about the gaming machine chip information, the CU control unit 323 and the SC 325b do not wait for a response from the host device, and process the next step (for example, authentication processing of the communication control IC, authentication processing of the security board information, gaming machine Business message processing, etc.) and the processing necessary when the gaming machine chip information is received.

  However, after that, the CU control unit 323 determines that the waiting time for the gaming machine chip information inquiry has timed out before receiving the gaming machine chip information inquiry result (main control chip information and payout control chip information) from the host device. The CU 3 transmits a status information request command for requesting information on the status of the P platform 2. The status information request command is encrypted using a communication key as an encryption key. The SC 325b that has received the status information request command acquires the gaming machine chip information of the P unit 2 via the communication control IC 325a.

  Then, the SC 325b returns a response of the status information response to the CU 3. At this time, the SC 325b returns a status information response including “chip information inquiry present” indicating that an inquiry to the key management center for gaming machine chip information is requested.

  In response to the above gaming machine chip information inquiry, the CU control unit 323 transmits a gaming machine chip inquiry instruction notification command to the SC 325b in order to request information for inquiring of the host device. Note that the gaming machine chip inquiry instruction notification command to be transmitted is encrypted using a communication key as an encryption key.

  Upon receiving the gaming machine chip inquiry instruction notification command, the SC 325b notifies the CU control unit 323 of information (main control chip information and payout control chip information) for inquiring of the host device (specifically, the key management server via the hall server). In order to do this, the response of the gaming machine chip inquiry result is sent back to the CU control unit 323 again. Note that the response of the game machine chip inquiry instruction notification to be returned is encrypted with the main control chip ID and the payout control chip ID using a secret key, and the other information is encrypted using a communication key as an encryption key.

  The CU control unit 323 that has received the response of the gaming machine chip inquiry result sends the gaming machine chip information (mainly the main management chip information and the payout control chip information) to the host device (specifically, the key management server via the hall server). Control chip information and payout control chip information) and continue to wait for a response from the host device.

  Characteristic parts of the sequence between the CU control unit 323 and the SC 325b described with reference to FIGS. 41 to 51 will be described below.

  There is a “board initial key authentication sequence” (see FIG. 41) as a sequence executed after the CU 3 is received and installed in the amusement hall. This "Board Initial Key Authentication Sequence" is obtained by downloading the board initial key from the host device (hall server) and authenticating using the board initial key when the power is turned on for the first time after being installed in the amusement hall. Sequence. On the condition that the authentication result of this board initial key authentication sequence is OK, the “security board information inquiry sequence” is executed using this board initial key (see FIG. 41). The board authentication key is downloaded and stored from the host device (key management server) by this security board information inquiry sequence, and thereafter, various authentication sequences, communication key exchange sequences, etc. are executed using this board authentication key, and the communication key is obtained. Using this, business message communication with the gaming machine is executed (see FIG. 42).

  On the other hand, as a result of executing the security board information inquiry sequence (see FIG. 41) using the board initial key, the board authentication key may not be acquired. The board authentication key is sent to the key management server by the CU manufacturer when the CU manufacturer ships CU3 to the game hall, and stored in the key management server. The board authentication key stored in advance in the key management server is downloaded and stored, but the transmission of the board authentication key from the CU manufacturer to the key management server may be delayed for some reason. In addition, when the CU3 installed in the amusement hall attempts to download the board authentication key by executing the security board information inquiry sequence, an unexpected situation occurs between the key management server and the CU3 and communication is impossible. May be offline. In such a case, the board authentication key cannot be downloaded.

  If the board authentication key cannot be downloaded and the actual operation such as business message communication with the gaming machine after that cannot be performed at all, operational problems such as a decrease in the operating rate at the amusement hall occur. Therefore, when such an unforeseen situation occurs, control is performed so that the temporary operation of the actual operation can be performed using the board initial key which is a temporary authentication key. Specifically, the communication key exchange sequence is executed using the board initial key acquired from the host device (specifically, the hall server), and the communication key (session key) is generated using the random number and the time data. Then, the communication key (session key) is shared between the CU control unit 323 and the SC 325b, and business message communication is performed using the communication key (session key), and actual operation control is performed. The actual operation control using the communication key exchanged using the board initial key is allowed only for a certain period because the board initial key is a temporary key and the board authentication key cannot be obtained. Temporary operation is controlled. Specifically, actual operation control using this board initial key is allowed for only two days, and when the board authentication key cannot be obtained even at the time of power-up on the third day, the subsequent control is stopped, Control is performed to notify that an abnormality has occurred and to notify the hall server or hall management computer that an abnormality has occurred. The temporary operation time limit control that is allowed for a certain period of time (for example, two days) with the board initial key is that the board initial key is stored in the hall server, so that at least the CU control unit 323 has the hall server. It is allowed in a state where it is guaranteed that it is connected to

  Further, the above-mentioned “substrate initial key / shipping key authentication sequence” is executed at the time of factory shipment shown in FIG. When the board initial key authentication sequence is executed at this stage, since the board initial key has not yet been acquired, the result of execution of this board initial key authentication sequence using the board initial key is derived as the NG authentication result. The Then, each sequence after the board shipping key request and the board shipping key response shown in FIG. 45 is executed, and communication between the gaming machine and the communication test message is executed. In other words, it is determined by the “substrate initial key / shipping key authentication sequence” whether the substrate initial key has been acquired or not at the time of factory shipment. The sequence is also effectively used to determine whether the initial stage key has been acquired or whether the initial stage key has not been acquired.

<Main sequence in communication between communication control IC and security chip>
Next, FIG. 52 is a diagram for explaining processing of a business message sequence between the SC 325b and the communication control IC 325a. With reference to FIG. 52, the processing of the SC 325b and the communication control IC 325a after the CU 3 is turned on will be described.

  First, when the power of the CU3 is turned on, the SC 325b and the communication control IC 325a are activated. When activated, the SC 325b performs authentication with the CU control unit 323, and when activated, the communication control IC 325a performs authentication with the gaming machine.

  Thereafter, the SC 325b and the communication control IC 325a perform the communication control IC authentication sequence using the authentication key or the temporary authentication key as the encryption key. In the “temporary authentication key mode” described with reference to FIG. 38, the temporary authentication key is used, and in the case of the main authentication key mode after the main authentication key is generated, the main authentication key is used.

  Thereafter, the SC 325b and the communication control IC 325a perform the security information update sequence using the main authentication key or the temporary authentication key as the encryption key. Further, the SC 325b and the communication control IC 325a perform a gaming machine chip information authentication sequence using the authentication key or the temporary authentication key as the encryption key.

  Thereafter, the SC 325b transmits a communication key request command for requesting a communication key to the communication control IC 325a. The communication key request command is encrypted using the authentication key or the temporary authentication key as the encryption key.

  Upon receiving the communication key request command, the communication control IC 325a generates a communication key (session key) for communicating the business message with the gaming machine, and notifies the generated communication key to the SC 325b in response to the communication key response. Note that the response of the communication key response to be returned is encrypted using the authentication key or the temporary authentication key as the encryption key. Specifically, the communication key (session key) is generated using a random number and current time data. The current time data may be generated by the communication control IC 325a itself or received from another device. The method for generating the communication key (session key) is not limited to the random number and the current time data, and any data may be used as long as it is variable data other than the key used for the above-described mutual authentication.

After the above process is completed, business message communication with the gaming machine becomes possible.
FIG. 53 is a flowchart for explaining specific control of “authentication using a board authentication key”. Referring to FIG. 53, a series of processing described below is performed between CU control unit 323 and SC 325b.

  In step S201, an authentication process (unit authentication) using a board serial ID is performed using a challenge response method (see board serial ID authentication request / responses 1 and 2 in FIG. 46).

  When the single authentication in step S201 is completed, the key version is checked in the next step S202 (see version information notification / response in FIG. 46).

  When the key version check in step S202 is completed, device authentication using the board authentication key is performed in the next step S203 (see board authentication key authentication request / responses 1 and 2 in FIG. 46).

  When the device authentication process in step S203 is completed, the authentication results in steps S201 to S203 are mutually notified in the next step S204, and the process proceeds to the next step S205 (board authentication result notification / response in FIG. 46). reference).

  In step S205, it is determined whether or not the notified authentication result is normal. If the authentication result is normal, the process proceeds to step S206. If the authentication result is not normal, the process proceeds to step S207.

  In step S206, it is further determined whether or not the CU control unit 323 has the security board information acquired from the SC 325b. If the CU control unit 323 has the security board information to be acquired, the process proceeds to step S209 to acquire the security board information. If the security board information is not included, the process proceeds to step S210.

  In step S209, the board authentication key authentication process between the CU control units 323 and SC325b further shifts to a security board information inquiry process, and the process ends. On the other hand, in step S210, the authentication in the board authentication key mode ends normally, and the process ends. In this case, the game machine chip information is collated between the CU control units 323 and SC325b.

  On the other hand, if the authentication result is not normal in step S205, the process proceeds to step S206. In step S206, it is determined whether or not the number of retries is the third time. If the number of retries is the third time, the process proceeds to step S208, and the number of retries is not the third time (the number of retries is the first or second time). If so, the process returns to step S201, and the authentication process is performed again.

  In step S208, the SC325b board authentication abnormality is set to a standby state until a reset operation (for example, operation of a reset button (not shown) or power-on). After the reset operation, it is activated again in a mode for performing an authentication process using the board initial key as an encryption key (board initial key mode), each authentication process is performed, and the process ends. In this case, the business of that day is operated in this board initial key mode throughout the day, and when the power is turned on the next day, a security board information acquisition request is issued again to the key management server to try to obtain security board information (see FIG. 50). Further, as shown in step S208a, the inquiry process for the security board information may be executed again at this time without waiting for the power-up of the next day. In this case, while the game is progressing by the operation in the board initial key mode, the inquiry process of the security board information is also advanced in parallel.

  FIG. 54A is an example of a flowchart for explaining the communication mode switching process between the CU control unit and the SC. Referring to FIG. 54A, in step S211, the CU control unit 323 requests a board authentication key from the key management server, and the process proceeds to the next step S212.

  In step S212, the CU control unit 323 obtains a board authentication key from the security board information sent from the key management server, and transmits update information in the security board information to the SC 325b, and next step S213. The process proceeds.

  In step S213, the CU control unit 323 determines whether or not the gaming machine is in a non-operating state. When the mode switching process in the next step S214 is performed, the number of balls added / subtracted cannot be communicated with the gaming machine that is executing the switching process, so that the gaming machine is not in operation before the mode switching process in step S214. It is determined whether or not. Whether or not the gaming machine is in a non-operating state is determined based on whether or not a player's card is inserted in the CU. When no card is inserted, the gaming machine is determined to be in an inoperative state, while when a card is inserted, the gaming machine is determined to be in an operating state. If the gaming machine corresponding to the CU control unit 323 is in a non-operating state, the process proceeds to step S214. If the gaming machine corresponding to the CU control unit 323 is not in a non-operating state, the gaming machine is in a non-operating state. Step S213 is performed until.

  In step S214, based on the board authentication key acquired in step S212, the CU control unit 323 advances the process using the board authentication key as the encryption key from the mode in which the board initial key is used as the encryption key (board initial key mode). The communication mode is switched to the mode (board authentication key mode), and the process ends.

  FIG. 54B is an example of a flowchart for explaining a communication mode switching process between the SC and the communication control IC. Referring to FIG. 54B, in step S216, the SC 325b acquires update information from the CU control unit 323. As described above, the CU control unit 323 transmits update information to the SC 325b in step S212. Receiving it, the SC 325b acquires the update information. Next, in step S217, the SC 325b generates this authentication key from the acquired update information. Next, similarly to step S213 described above, in step S218, the SC 325b determines whether or not the gaming machine is in a non-operating state, and executes the process of step S219 on the condition that it is in a non-operating state. In step S219, the SC 325b uses the authentication key as the encryption key from the mode (provisional authentication key mode) in which the temporary authentication key is used as the encryption key for the communication mode between the SC 325b and the communication control IC 325a based on the generated authentication key. Switch to the mode to proceed with the process (this authentication key mode).

  According to such an embodiment, before the authenticity of the CU is authenticated by the board authentication key registered in the key management server, a normal communication mode is entered and the game on the P cards using the remaining card amount is performed. It can be prevented from becoming possible. Furthermore, even when the board authentication key registered in the key management server cannot be received, the restricted communication mode is set and a game on the P units is allowed, so that flexible operation is possible. In addition, in this case, since the game is allowed under a predetermined restriction compared to the normal communication mode, the operation can be performed without requiring authentication with the board authentication key stored in the key management server. It can be prevented from continuing.

  FIGS. 55A and 55B are other examples of a flowchart for explaining the communication mode switching process. Referring to FIG. 55A showing the communication mode switching process between the CU control unit and the SC, in step S221, the CU control unit 323 requests security board information from the key management server, and the next step S222 is performed. The process proceeds.

  In step S222, the hall server acquires the security board information requested by the CU control unit 323 from the key management server from the key management server, and the hall server acquires the board authentication key from the security board information. Next, in step S223, the hall server determines whether or not the gaming machine corresponding to the CU control unit 323 that has requested the security board information is in a non-operating state for the same purpose as in step S213 described above. When the gaming machine becomes non-operating, the hall server transmits the acquired board authentication key to the CU control unit 323 in step S224, and the CU control unit 323 that has received the update information in the security board information is SC325b. Send to. Next, in step S225, based on the board authentication key acquired in step S2224, the CU control unit 323 performs processing using the board authentication key as the encryption key from the mode in which processing is performed using the board initial key as the encryption key (board initial key mode). The communication mode is switched to the mode (board authentication key mode) to advance the process, and the process ends.

  Next, with reference to FIG. 55 (b) showing processing for switching the communication mode between the SC and the communication control IC, the SC 325b acquires update information from the CU control unit 323 in step S226. As described above, the CU control unit 323 transmits update information to the SC 325b in step S224. Receiving it, the SC 325b acquires the update information. Next, in step S227, the SC 325b generates this authentication key from the acquired update information. Next, in step S228, the SC 325b obtains the authentication key from the mode (provisional authentication key mode) in which the temporary authentication key is used as the encryption key for the communication mode between the SC 325b and the communication control IC 325a based on the generated authentication key. Switch to a mode in which processing is performed as an encryption key (this authentication key mode).

  According to such an embodiment, even when the hall server receives the board authentication key from the key management server in the restricted communication mode, the board authentication key is immediately transmitted to the CU when the P units are in operation. Provided in the restricted communication mode because the board authentication key is sent from the hall server to the CU and switched to the normal communication mode on the condition that the gaming machine is in a non-operating state, instead of switching to the normal communication mode. It is possible to prevent the player from suffering any disadvantages by affecting the game that has been played.

<Authentication operation between SC 325b and CU control unit 323>
Next, the unified store code check and the board manufacturer code authentication will be described in more detail.

  First, with reference to FIG. 56, the unified store code check process by SC325b will be described. This process is an authentication operation in which the SC 325b checks the unified store code notified at the time of the board connection request and the unified store code notified last time, and determines that the installed store has changed when there is a mismatch. The SC 325b determines whether or not the stored previous unified store code is a dummy code (step S1101). For example, all data of the dummy code of the unified store code is “0xFF”. This dummy code is used in place of the normal unified store code at the time of shipment before the CU 3 is installed in the amusement hall (store), and is already stored in the SC 325b at the time of shipment. Then, at the time of shipment, a dummy code is input to the SC 325b via the CU control unit 323, and the SC 325b determines that the input dummy code matches the stored dummy code and authenticates it. The dummy code is stored as a default in the hall server of the amusement hall as a temporary shop code when a unified store code has not yet been acquired for a newly opened game hall (hall). Then, the dummy code is downloaded from the hall server to the CU 3 installed in the game hall of the newly opened store, and the SC 325b determines that the downloaded dummy code matches the stored dummy code and authenticates it. Allows gaming.

  The hall server that has acquired the regular unified store code transmits the unified store code to the CU control unit 323. Upon receiving the request, the CU control unit 323 transmits the unified store code to the SC 325b when the board connection is requested at the next power-on. Receiving it, SC325b, when determining that the previous unified store code stored is a dummy code (step S1101: YES), updates the memory to the unified store code notified from the hall server at the time of board connection request. However, it does not initialize the board authentication key and the main authentication key information and operates by taking over the previous authentication modes. Thereafter, the SC 325b stores the authentication log information (step S1106). The initialization of the board authentication key and the main authentication key information is a process required when the CU 3 installed in a certain game arcade is moved to another game arcade, but is a dummy code stored in the SC 325b. Is updated to the unified store code, the amusement hall of the newly opened store obtains the unified store code and downloads the unified store code to the CU3. It is not necessary to initialize the key and the authentication key information. Conversely, if the board authentication key and this authentication key information are initialized in such a case, a request for obtaining the board authentication key is required again, increasing the number of board initial key operations (timed operation) in one business day, and timed operation. There is a disadvantage that the grace period is reduced. In order to avoid such inconvenience, control is performed so that the board authentication key and the main authentication key information are not initialized.

  On the other hand, if the SC 325b determines that the previous unified store code stored is not a dummy code (step S1101: NO), the unified store code notified from the hall server at the time of board connection request and the stored previous store code are stored. It is determined whether or not the unified store code matches (step S1102).

  If the SC 325b determines that the unified store code notified from the hall server at the time of board connection request matches the previous unified store code stored (YES in step S1102), the authentication process is performed on the board initial key. Transition to an authentication sequence, or transition to a board authentication key authentication sequence (step S1103). Note that the SC 325b transitions to the board authentication key authentication sequence when the previous authentication mode is the board authentication key mode, and shifts to the board initial key authentication sequence when the previous authentication mode is any other authentication mode.

  On the other hand, if the SC 325b determines that the unified store code notified from the hall server at the time of board connection request does not match the previous unified store code stored (step S1102: NO), the board authentication key information The authentication key information is initialized (cleared) (step S1104). Such a mismatch in the unified store code occurs when the CU 3 installed in a certain game hall is moved to another game hall. Since CU3 has been moved to another amusement hall, the board authentication key information and the main authentication key information used in the previous amusement hall are initialized (cleared) to ensure security. When the unified store code notified from the CU control unit 323 is changed, the SC 325b sets initialization (clear) of the authentication key in the communication control IC 325a and starts authentication with the temporary authentication key. Note that when the SC 325b initializes (clears) the authentication key information, the communication control IC 325a may also control to initialize (clear) the authentication key information, and particularly performs such control. Without authentication, since the SC 325b is not the main authentication key at the time of the next authentication with the communication control IC 325a, the authentication may return to the temporary authentication key.

  Further, the SC 325b initializes (clears) the board authentication key information and the main authentication key information in step S1104, and then transitions the authentication process to the board initial key authentication sequence and the temporary authentication key sequence (step S1105).

  In step S1103, the SC 325b transitions the authentication process to the board initial key authentication sequence, or transitions to the board authentication key authentication sequence. In step S1104, the SC 325b stores the authentication log information after transitioning to the board initial key authentication sequence. (Step S1106).

  FIG. 57 is a flowchart for explaining the board manufacturer code authentication operation. The board manufacturer code authentication is an authentication operation in which the SC 325b and the CU control unit 323 perform authentication using the board manufacturer code stored as initial information. Referring to FIG. 57, first, SC 325b and CU control unit 323 perform unit authentication by a challenge / response method using the stored board manufacturer code. (Step S1201). The response code generated at the time of single unit authentication is generated, for example, by performing block encryption of the challenge code using the stored board manufacturer code as a key and then hashing with a hash function.

  The SC 325b determines whether the authentication result obtained by checking the response code generated by the CU control unit 323 with respect to the generated challenge code is normal (step S1202). If the SC 325b determines that the authentication result is normal (step S1202: YES), the SC 325b determines whether it has already been authenticated with the board authentication key (step S1203). On the other hand, when the SC 325b determines that the authentication result is not normal (abnormal) (step S1202: NO), the SC 325b determines whether it is abnormal continuously (eg, three times) n times (step S1204).

  If the SC 325b determines that the board authentication key has already been authenticated (step S1203: YES), the process proceeds to the board authentication key authentication process and maintains the board authentication key authentication sequence (step S1205). On the other hand, if the SC 325b determines that the board authentication key has not been authenticated (step S1203: NO), the process proceeds to the board initial key authentication process (step S1206).

  SC325b returns a process to step S1201, when it is judged that it is not abnormal continuously n times (step S1204: NO). On the other hand, when the SC 325b determines that the abnormality is continuous n times (step S1204: YES), the board authentication key information and the main authentication key information are initialized (cleared) to ensure security (step S1207). . Thereby, the inconvenience that the board authentication key information and the main authentication key information are stolen can be prevented. Thereafter, the SC 325b makes a transition to a board initial key authentication process (step S1208).

  In step S1205, the SC 325b maintains the board authentication key authentication sequence, or transitions to the board initial key authentication process in steps S1206 and S1208, and then stores the authentication log information (step S1209).

<Health Check>
Next, in the gaming system according to the present embodiment, for example, even when communication between the CU 3 or P table 2 and the key management server is interrupted, the CU 3 or P table 2 is stably operated. It is possible to continue operation using the timed operation function. However, there is a possibility that the CU 3 and the P stand 2 are operated without performing communication with the key management server by intentionally using the timed operation function, and unauthorized business may be performed. Therefore, in the present embodiment, when the CU 3 or P unit 2 operating using the timed operation function continues to be disconnected from the key management server for a predetermined period, the timed operation function Is configured to be disabled. In the present embodiment, even if the timed operation function of the CU 3 or P unit 2 is disabled, the setting of the timed operation function is enabled again when communication with the key management server is recovered and a predetermined condition is satisfied. It is.

  FIG. 58 is a diagram for explaining processing for invalidating the timed operation function in the gaming system according to the present embodiment. With reference to FIG. 58, processing for invalidating the timed operation function will be described. A process for invalidating the timed operation function is a predetermined process performed between the key management server 800 and the hall server 801, between the hall server 801 and the CU control unit 323, and between the CU control unit 323 and SC 325b.

  First, the CU 3 including the CU control unit 323 and the SC 325 b communicates with the P stand 2 so that the player can play a game with the P stand 2. At this time, for example, in communication between the CU control unit 323 and SC 325b, encryption communication based on the secret key A is performed, and a status information request command from the CU control unit 323 is also a response of a status information response from the SC 325b. Is also encrypted based on the secret key A.

  The secret key A is regularly updated by a health check from the key management server 800, so that communication between the CU control units 323-SC325b can be normally performed. The key management server 800 shown in FIG. 58 transmits a health check request command to the CU control unit 323 and the SC 325b to perform a health check during normal communication between the CU control unit 323 and the SC 325b. However, since the communication between the key management server 800 and the hole server 801 is not connected, the health check request command does not reach the CU control unit 323.

  The health check from the key management server 800 is performed once a day, for example, and the health check response to the transmitted health check request cannot be obtained because the communication between the key management server 800 and the hall server 801 is not available. The health check request is sent on the next day without re-sending.

  The communication between the CU control units 323 to SC 325b continues communication without any restriction because of the timed operation function even when the health check from the key management server 800 is not performed and the secret key A is not updated. Can be done. Therefore, communication between the CU 3 and the P stand 2 can be performed normally, and the CU 3 and the P stand 2 can be normally operated to enable the P stand 2 to operate.

  However, when the key management server 800 transmits a health check request command and does not reach the CU control unit 323, for example, 10 days (10 times if health check is performed once a day) continues. It is determined that the health check request time limit is exceeded. If it is determined that the health check request time limit is exceeded, the SC 325b disables the timed operation function and cannot perform communication between the CU control unit 323 and the SC 325b using the secret key A. When the secret key A cannot be used in the communication between the CU control units 323 and SC325b, the communication content is greatly limited, and the communication between the CU3 and the P stand 2 is also limited. Therefore, the operation of the CU 3 and the P stand 2 can be disabled, or can be operated with significant restrictions.

  In the communication between the CU control units 323 to 325b, the encryption communication based on the secret key A is not performed, and neither the status information request command from the CU control unit 323 nor the response of the status information response from the SC 325b is the secret key. Not encrypted based on A. Instead, communication may be performed by encryption based on the initial key A held in the CU control unit 323 or the SC 325b, for example. In this case, for example, commands that can be communicated between the CU control units 323 to SC 325b are greatly limited.

  As described above, in this embodiment, the timed operation function is invalidated when the state in which communication with the key management server is interrupted cannot be continuously checked for a predetermined period of time, so the timed operation function is used. Thus, it is possible to prevent the P platform 2 from operating illegally. The invalid condition for disabling the timed operation function is that there is a period during which the health check cannot be performed for 10 days. However, the health check request command is not received and the response of the health check response cannot be received. It may be a condition that the predetermined number of times has been reached.

  Next, processing for enabling the timed operation function for a gaming system in which the timed operation function is disabled will be described. FIG. 59 is a diagram for explaining processing for enabling the timed operation function in the gaming system according to the present embodiment. With reference to FIG. 59, processing for enabling the timed operation function will be described. The process for enabling the timed operation function is performed in a predetermined process between the key management server 800 and the hall server 801, between the hall server 801 and the CU control unit 323, and between the CU control unit 323 and SC 325b.

  First, the CU 3 including the CU control unit 323 and the SC 325b communicates with the P-unit 2, sends a status information request command from the CU control unit 323 to the SC 325b, and receives the response of the status information response from the SC 325b. It is transmitted to the control unit 323. At this time, the CU control unit 323 and the SC 325b perform timed operation when an invalid condition is established in a state in which a health check response to the transmitted health check request cannot be obtained because communication between the key management server 800 and the hall server 801 is disconnected. The function is disabled.

  Thereafter, when the line between the key management server 800 and the hall server 801 is restored and communication is possible, a health check response to the health check request transmitted from the key management server 800 is obtained. The state in which the health check from the key management server 800 becomes possible has passed for three days, and the key management server 800 makes a health check request on the fourth day. If the health check can be performed, the communication between the CU control units 323 and SC325b performs the encryption communication based on the secret key A.

  Specifically, the key management server 800 transmits a health check request command to the hall server 801, and the hall server 801 receiving the command transmits a health check request command to the CU control unit 323. Further, the CU control unit 323 receives a command from the hall server 801 and transmits a board state request command including a health check request as additional information to the SC 325b.

  Upon receiving the board status request command from the CU control unit 323, the SC 325b enables the timed operation function that has been disabled because the line is restored and the health check has been normally performed for three days. By enabling the timed operation function, even if communication between the key management server 800 and the hall server 801 is interrupted in the future and the health check cannot be performed, the CU control unit 323 and the SC 325b use the timed operation function to keep it secret. Communication based on the key A can be performed. As a result, the CU 3 and the P platform 2 can be stably operated even if a failure such as a disconnection with the key management server 800 occurs.

  Further, the SC 325b receives a substrate state request command and transmits a substrate state response response including a health check response as additional information to the CU control unit 323. The health check response includes the state information of SC 325 b and the state information of P base 2 received from P base 2. Although not shown in FIG. 40, the SC 325b makes a health check request to the P base 2 and receives a health check response from the P base 2, thereby acquiring the status information of the P base 2.

  The CU control unit 323 receives a response of the substrate state response from the SC 325b, and transmits a response of the health check response to the hall server 801. The response of the health check response includes, for example, information on the authentication state between the CU control units 323 and SC325b. Further, the hall server 801 receives a health check response response from the CU control unit 323 and transmits a health check response response to the key management server 800.

  As described above, in this embodiment, the timed operation function is invalid when the health check can be performed continuously for a predetermined period when the line with the key management server is restored and communication is possible. Since it is enabled, it is possible to operate stably without impeding the operation of the amusement hall using the timed operation function. Further, since it is not necessary for the clerk to operate each CU 3 or P stand 2 in order to enable the timed operation function that is invalid, the work of the clerk can be reduced. Note that the return condition for enabling the timed operation function is that the health check can be performed for 3 days. However, the return condition is not limited to this, and a health check request command is sent to respond to the health check response. It is also possible to make it a condition that the number of times that can be received becomes a predetermined number. Also, the period during which health check is disabled (for example, 10 days), which is an invalid condition for disabling the timed operation function, is compared to the period during which health check is enabled (for example, 3 days), which is a return condition for enabling the timed operation function. This makes it possible to operate the CU 3 and the P stand 2 stably without impeding the operation of the game hall while preventing unauthorized use of the timed operation function.

<Slot machine>
Next, a slot machine will be described as another example of the gaming machine. FIG. 60 is a perspective view showing a state in which the front door of the slot machine is opened. In the description so far, the slot machine is also abbreviated as “S” in the following, because the pachinko gaming machine is abbreviated as “P”.

  The above gaming system using game balls and holding balls is also applied to the S units. However, in the S platform, the game is played without using balls, and hence the game balls will be referred to as game points and the holding balls as points.

  Referring to FIG. 60, a slot machine (hereinafter sometimes abbreviated as a gaming machine or S unit) 2S is provided such that front door 2bS is openable and closable with respect to main body frame 2aS with its left edge as a swing center. It has been. Although not shown in FIG. 60, a CU is connected to the left side of the S base 2S in the same manner as the P base.

  In S 2S, the number of bets is set by using the game points, and the game points are added and updated in accordance with the winning. For this reason, when a game is played on the S platform 2S, a medal insertion operation is not necessary. Therefore, the S stand 2S is not provided with a medal insertion slot and a medal payout opening.

  Inside the casing of the S unit 2S, reels 2L, 2C, and 2R (hereinafter also referred to as a left reel, a middle reel, and a right reel) in which a plurality of types of symbols are arranged on the outer periphery are juxtaposed in a horizontal direction. Of the symbols arranged on the reels 2L, 2C, and 2R, three consecutive symbols are arranged so that they can be seen from the see-through window provided on the front door 2bS. A plurality of types of symbols are drawn in a predetermined order on the outer peripheral portions of the reels 2L, 2C, and 2R.

  A touch panel display 510 is provided in a portion surrounding each reel 2L, 2C, 2R of the front door 2bS. The display 510 is a display corresponding to the P displays 54, and displays various types of information (game points, points, etc.) of the same type as the display 54, as well as the number of bets set in the game. Is displayed. The display unit 510 is connected to the CU display control unit 350 in the same manner as the display unit 54 in FIG. 4 and is controlled on the CU side. The indicator 510 is not provided in a portion surrounding each of the reels 2L, 2C, 2R, but is provided at a lower panel portion (at a position below the start switch 7S shown in FIG. You may provide in the panel part provided with the conventional S medal payout opening.

  Further, the front door 2bS has a single BET switch 5S that is operated when setting the number of bets using “game points = 1” corresponding to one medal, and the maximum determined according to the game state. When setting the number of bets (for example, “game point = 3” in the normal game state before BB occurrence and RT (Replay Time) where the winning probability of replay is high, “game point = 2” in the bonus) The MAXBET switch 6S is operated, the start switch 7S is operated when the game is started, and the stop switches 8L, 8C, 8R are respectively operated when the rotation of the reels 2L, 2C, 2R is stopped. Yes.

  In the case of playing a game on the S machine 2S, first, similarly to the P machine, after securing a game point using the adjacent CU, the number of bets is set using the game point. The game points can be obtained by withdrawing the remaining amount of the prepaid card inserted into the CU, points, or a stored medal (corresponding to P stored balls) deposited in the game hall. In order to use the game points, the single BET switch 5S or the MAXBET switch 6S may be operated. In the present embodiment, for example, by setting the number of bets to 1, the game points are deducted by 1, and the display of the game points on the display 510 is also subtracted and updated. When the bet number is set, the pay line determined according to the bet number and the gaming state is valid, and the operation of the start switch 7S is valid, that is, the game can be started.

  When the start switch 7S is operated while the game can be started, the reels 2L, 2C, and 2R rotate, and the symbols of the reels 2L, 2C, and 2R continuously change. When any one of the stop switches 8L, 8C, 8R is operated in this state, the rotation of the corresponding reels 2L, 2C, 2R is stopped, and the display result is derived and displayed on the fluoroscopic window.

  Then, when all the reels 2L, 2C, 2R are stopped, one game is completed, and a predetermined symbol combination (hereinafter also referred to as a role) on the activated pay line is displayed on each reel 2L, 2C, When the 2R display result is stopped, a prize is generated, a game point determined according to the prize is given to the player, and the display of the game point on the display 510 is also added and updated.

  In the case of S units, it is possible to count game points as in the case of P units. As shown in FIG. 1, the S stand 2S is provided with a counting button 28S for counting game points and converting them into points. The ball lending button, the card return button, and the replay button are provided on the CU side (see FIG. 4). The player executes the counting operation based on an arbitrary timing or a display for prompting the counting operation on the display unit 510 in the same manner as the P units. Then, the game points are counted and the display 510 displays a state in which the points are increased while the game points are decreased. The ball lending button may be provided not on the CU side but on the P platform side and the S platform side. In that case, the operation signal of the ball lending button may be directly input to the CU 3 or may be transmitted to the CU 3 as a status information response via the P unit 2 or the S unit (slot machine) 2S. It may be.

  The types of winning combinations are determined according to the state of the game, but can be broadly divided into special roles with a shift to the big bonus (BB) and regular bonus (RB), and small roles with payout of medals. And a re-gamer (replay) that allows the next game to be started without the need to set the bet amount.

  Which of a plurality of types of winning combinations is to be won or whether any winning combination is to be excluded is determined by, for example, a main control unit (S) that controls the S base 2S when a start operation is detected. It corresponds to the main control unit 161 of the stand). This determination is made, for example, by drawing a random number generated from a predetermined random number generator or generated on software.

  After that, the main control unit waits for the reel stop operation by the player, draws in the symbol corresponding to the winning combination in the predetermined frame number range based on the stop operation time, otherwise draws another symbol Is controlled to stop the three symbols and determine whether or not there is a prize. If the main control base determines that a winning is made, the main control base gives the player game points according to the type of winning (adds game points).

  The payout control unit of the S platform 2S is mounted on a payout control board (not shown). The payout control board is delivered from the frame maker to the hall in a state of being attached to the main body frame 2aS by the frame maker.

  On the other hand, the main control board (not shown) of the S platform 2S is delivered to the hall from the slot machine manufacturer separately from the main body frame 2aS in a state of being attached to the board mounting board for connecting the wiring. The board mounting board is a board corresponding to the game board 26 shown in FIG. 3, and includes a connector similar to the convex drawer connector 32 provided on the game board 26.

  To connect a mounting mechanism for mounting the board mounting board and a convex drawer connector on the board mounting board side to a predetermined position (for example, below the reels 2L, 2C, 2R) in the main body frame 2aS of the S base 2S. The connector is provided. The attachment mechanism and the connector have the same structure as the attachment mechanisms 34a and 34b and the concave drawer connector 33 shown in FIG. 3, and are devised so that the board attachment board can be easily fixed to the attachment mechanism. The wiring extending from the concave drawer connector is connected to the reels 2L, 2C, 2R, various operation switches (buttons), and the like.

  The S base 2S has a configuration for detecting the opening of the front door 2bS corresponding to the front frame 5 of the P base 2 and detecting the connection between the main body frame 2aS and the board mounting board. The main control board is also connected in series.

  With the S units, the game can be started by setting a predetermined number of bets for one game using the gaming value, and variable display capable of variably displaying a plurality of types of identification information each of which can be identified A slot machine in which one game is completed when a display result is derived to the device and a winning can be generated according to the display result derived to the variable display device, and the display result is displayed on the variable display device. Before deriving, predetermining means for determining whether or not to allow a plurality of types of winnings to occur, and control for causing the variable display device to derive a display result according to the determination result of the predetermining means A slot machine is configured that includes a derivation control means for performing and a granting means for imparting a game value when the winning occurs.

  FIG. 61 is an explanatory diagram for explaining various data stored in each of the card unit and the slot machine and its transmission / reception mode. The transmission / reception mode shown in FIG. 61 is obtained by replacing the terminology in FIG. 37 described as the configuration of P units with that for S units, and the mode is the same as that described with reference to FIG. Here, further explanation is omitted.

<Modifications and feature points>
Next, modifications and feature points of the present embodiment described above are listed.

  (1) In this embodiment, the addition sequence number and the counting sequence number are defined in the message format as different data, but these may be shared as a request sequence number. In particular, the addition of game balls and the counting of game balls are the opposite processes, so it is unlikely that both processes will occur at the same time. From this point of view, it is possible to reduce the amount of message data by sharing both serial numbers. It is.

  Further, in the present embodiment, when a new request is generated until the request sequence number reaches a predetermined upper limit value, the sequence number is updated based on the previously updated value. However, instead of such control, when all the processes corresponding to one request are completed, the request sequence number may be initialized to a predetermined initial value.

  Request sequence numbers such as addition sequence numbers and count sequence numbers, and normal sequence numbers are not counted up one by one, but are updated (additional update, subtraction) according to a predetermined rule stored in both P unit 2 and CU3. Update, update by other arithmetic expressions). In this case, the serial number is not “sequential numbers” such as 1, 2, and 3, but data that is updated based on concepts such as A, B, and C.

  (2) When a slot machine (S units), which is an example of a gaming machine, is applied to the gaming system, for example, a game in which there are P reels and various sensor parts attached to the reels and a main control board that controls the reels. Corresponding to the board, the other configuration corresponds to the front frame of the P units. However, the various detection switches 41a, 701, and 33, the firing control board 31, and the firing motor 18 in the front frame shown in FIG.

  A conventional S unit is provided with a credit function. When this function is enabled, the credit is subtracted when the number of bets is set, and the credit is added when a winning occurs. However, there is an upper limit for credits, and when a winning occurs when the number of credits reaches the upper limit value, medals are paid out from the hopper.

  On the other hand, in the S units according to the present embodiment, game points are subtracted when the bet number is set, and game points are added when a winning occurs. Further, when the game points reach a predetermined number, a display for prompting a counting operation is made, and the gaming points are converted into points by performing the counting operation. For this reason, it is not necessary to pay out medals when the credit reaches the upper limit unlike the conventional S units. As a result, it is not necessary to provide a hopper on the S platform according to the present embodiment.

  As a result, the amusement hall does not need to secure a large number of medals, reducing the economic burden. The game arcade is also freed from operations such as replenishment / collection of medals and maintenance operations to deal with clogged medals. The player is relieved from the hassle of inserting medals for each betting operation after the credit is full, and can easily concentrate on the game.

  On the other hand, if S units become medalless, a player who has won a large number of medals will not be able to act to show off his arms by stacking boxes with medals beside the seat. Inconvenience arises. However, in this embodiment, since the function of displaying the dollar box is provided as described above, it is possible to prevent such inconvenience. In addition, it is desirable for the dollar box display in the case of S units to have a large number of medals loaded instead of a large number of balls.

  When S machines are applied as a gaming machine, each type of data is expressed as follows using two types of data, “Points” and “Game Points”, and “Credit” and “Credit Excess Points”. It is also possible to configure a gaming system that is converted. Note that these four types of data are displayed on the S displays 510 or 29S.

  First, when a conversion operation (lending operation, saving medal payout operation, point payout operation) from the remaining amount of a prepaid card, a saving medal, or a point is detected, each is withdrawn and converted into a game point. The

  A game point is data corresponding to a medal in a conventional slot machine. For this reason, for example, it is desirable to display the number of game points on the display 510 or the display 29S, and to display the number of medal images corresponding to the game points. For example, when a pseudo-insertion medal operation (for example, an operation of pushing a medal) such that a player touches the medal image and inserts it into the slot machine is detected, the medal image disappears and the game points are subtracted. Instead, one bet is set. By performing such a pseudo medal insertion operation three times, the bet number is set to the maximum value of three.

  Thereafter, when a pseudo medal insertion operation is further detected, a credit is added in accordance with the detection. An upper limit value (for example, 50) is set for the credit, and when the credit exceeds the upper limit value, a credit excess point is added.

  The betting amount setting can be performed using the game points as described above, and can also be performed using credits. That is, if the one-sheet BET switch 5S is operated, 1 is added to the betting number setting value and 1 is subtracted from the credit. If the MAXBET switch 6S is operated, the bet number is set to 3, and the credit is subtracted according to the bet number setting.

  As a result of the game, when a winning occurs, a number of points corresponding to the winning is added to the credit. When a winning that exceeds the upper limit of credit occurs, the score for the excess is stored as a credit excess point. This credit excess point corresponds to a medal to be paid out when a winning occurs exceeding the upper limit of credit in the conventional slot machine. For this reason, for example, it is desirable to display the credit excess points on the display 510 or the display 29S and to display the number of medal images corresponding to the credit excess points. Further, it is desirable to change the color of this medal image so that it can be distinguished from the medal image corresponding to the game point.

  Further, it is desirable that the credit excess points are converted into game points by the player's operation. For example, when a pseudo medal conversion operation (for example, an operation of pushing a medal) is performed such that the player touches the medal image corresponding to the credit excess point and converts it to a game point, the medal image disappears and the credit excess Points are subtracted and game points are added.

  Alternatively, if the credit becomes less than the upper limit value, the credit excess point may be automatically converted into credit.

  When the player performs a counting operation, each of the game points, credits, and credit excess points is counted and converted into points. As a result, the player's points are posted as “card possession number + game points + credits + credit excess points”. The “card possession number” is the number of points before conversion (the number of possessions currently owned by the player) that has not been converted into game points.

  In the above description, the four types of data of points, game points, credits, and credit excess points may be stored on both sides by exchanging data between the CU and S units. You may memorize | store only in the S stand side only by CU side. Further, the credit excess point may be a target for dollar box display.

  Moreover, although the example using a credit excess point was demonstrated in the above description, it is not necessary to use a credit excess point. In this case, when the credit limit is exceeded, it may be added to the game points.

  (3) In the present embodiment, game points are added by consuming card power. Alternatively, game points are added by consuming stored balls (stored medals). That is, the card frequency or the stored ball is converted into game points. On the other hand, the card power and the stored balls are not converted into points (count balls, count medals). However, the card power and the stored ball may be once converted into points.

  (4) In the present embodiment, game points are converted into points by counting operation. The conversion rate in this case is 1: 1. However, the conversion rate in the case of conversion may be other than 1: 1. For example, when 100 game points are converted, 97 points obtained by subtracting three of them may be converted into points. Or you may make it convert into the number of game balls obtained by multiplying a predetermined ratio of less than 100% with respect to a point.

  (5) The recording medium for recording the holding point in an identifiable manner may be one using a mobile terminal such as a smartphone. In this case, the communication unit for communicating with the mobile terminal is provided in the CU, and the CU recognizes the ID stored in the mobile terminal by holding the mobile terminal over the communication unit. The game is made possible by the procedure as described. On the other hand, at the end of the game, the portable terminal is again held over the communication unit, so that the score at the end of the game is added to the player's score through the ID.

  (6) The operation means for counting game points may be provided on the CU side. In this case, the operation means may be displayed on a touch panel, or may be constituted by a physical switch.

  (7) In the present embodiment, when an uncounted game point remains when a card return operation is performed, a message prompting for counting is displayed on the display of P units or the CU side. However, instead of such a configuration, when an uncounted game point remains when the card return operation is performed, the counting display is automatically started and the display on the P table or the CU side is used. It may be notified that automatic counting has started because there are still uncounted game points, or that, in addition, the card will be returned after completion of automatic counting.

  Alternatively, when an uncounted game point remains when the card return operation is performed, it is determined that there is a possibility that the player may leave the table temporarily, and the display (CU side or P stand side) You may display the message which confirms whether it is temporary leaving. Further, the display device may be constituted by a touch panel so that the player can input a response to the message. Furthermore, if the response input is the end of the game, a message prompting the counting operation is displayed. On the other hand, if the response input is temporarily away from the desk, the card may be temporarily ejected while the ID of the card is stored on the CU side, the P platform side, or both. Thereafter, when a card with the same ID is inserted, the game is resumed from the original state.

  (8) During the big hit, the judgment reference value for judging that the number of game balls is full may be increased. In other words, the determination reference value for the full tank determination may be different depending on whether or not the big hit. As a result, it is possible to prevent the number of game balls from rapidly increasing during the big hit, and making a full tank determination immediately to stop firing.

  (9) The number of game balls when a big hit occurs is memorized. During the big hit, even if the criterion value for full tank is exceeded, the increased number of game balls allowed after the big hit has occurred If it is within a value (for example, 1000 balls), it is good also as what does not determine a full tank.

  (10) As the counting operation means for counting the game balls, one that exhibits a counting function when operated a predetermined number of times twice or more may be employed. As a result, erroneous operation can be prevented. Further, in this case, one function may be used to exhibit another function different from the counting function. For example, when there is no operation for a predetermined time (for example, within 1 second) after the operation is performed once, a function to turn on a lamp for calling a store clerk is exhibited, and within 1 second from 1 operation. When the second operation is detected, it is conceivable to perform the counting function.

  (11) “Predetermined processing” of “recording medium processing means for processing so that predetermined processing can be performed using the game point as the holding point when a predetermined recording medium processing operation is detected” , CU processing when using a card ejected from the CU inserted into another CU connected to another gaming machine (processing to withdraw the possessed ball that can be specified by the card and convert it into a gaming ball , Or shared ball processing, or wagon service processing). Alternatively, the “predetermined process” may be a process in which a prize is exchanged by receiving a card with a prize exchange machine for exchanging prizes and consuming the points specified by the card.

  Further, the above-described “recording medium processing operation for processing so that a predetermined process can be performed as a holding point” is, for example, a card return operation. In addition, the “predetermined process” is a process of recording a score so as to be specified on a card inserted in the CU when a card return operation is detected, and returning the card. Here, “recordably specified” means that the score is directly recorded on the card, and the card ID and score are recorded on the server connected to the CU without recording the score on the card. And a method of storing IDs and points in association with each other in the server.

  (12) If a counting operation is performed while the ball is being fired, the counting operation may be invalidated if the number of game balls at that time is equal to or less than a reference value. In addition, even when the number of game balls when the counting operation is detected during the ball firing exceeds the reference value, the number of balls counted in one counting operation is set to a predetermined number If the value obtained by subtracting the predetermined number from the number of game balls when the counting operation is detected is less than the reference value, the counting operation may be invalidated.

  Further, whether or not a game is in progress may be determined based on whether or not a ball launching operation has been detected, and the number of in-game balls (floating balls floating in the game area 27) becomes zero. Whether or not (not in game) or not (in game) may be determined. Further, it is conceivable to determine whether or not the game is in progress based on whether or not the variable display device is changing, whether or not it is a big hit, whether or not the attacker is open.

  Further, “in game” when S units are applied as a gaming machine and the counting operation during the game is invalidated is, for example, a period from the start of rotation of the reels 2L, 2C, and 2R to the stop. . Alternatively, it is a period from when the start operation is detected until the reels 2L, 2C, 2R are stopped.

  (13) In order to change the number of game points to be converted by one operation according to the time for which the counting button is kept pressed, for example, when a long press (for example, continuous operation for 1 second or more), While all are counted, only 200 balls may be counted in a short press (for example, continuous operation for less than 1 second). However, in this case, when the remaining number of game balls is small, for example, when it is less than 200 balls, it is desirable that all game balls are counted by operating the counting button.

  (14) When the number of points counted by one short pressing operation of the counting button is made different according to the remaining number of game points, for example, the following may be considered. For example, when the number of game points is less than 200, all the game points are counted by one short press operation of the counting button. When the game points are 200 or more and less than 1000, 200 points are counted by one short press operation. When the game points are 1000 or more and less than 5000, 1000 points are counted by one short press operation. When the game points are 5000 or more and less than 10,000, 2000 points are counted by one short press operation. When the number of game points is 10,000 or more, 2500 points are counted by one short press operation. The above numerical values are specific examples and can be set as appropriate.

  (15) When counting game balls (game points) and converting the points, not only counting display but also counting sound may be output from the speaker 270. In addition, when counting the game points, it is conceivable to display an image in which balls are dropped one by one from the ball storage tray to the counter.

  (16) Timing for performing conversion display (display indicating that game balls are counted and the number of balls is increased) based on the counting operation and subtracting game points on the data The timing for adding the points can be varied. The calculation may be executed after the conversion display is completed. For this purpose, count data may be transmitted from the gaming machine to the CU after the conversion display is completed. It should be noted that such a modification can be similarly applied to the case where the points are converted into game points.

  (17) In the present embodiment, in the communication between the CU and the gaming machine, a command-response system is adopted in which the CU is a primary station and the gaming machine is a secondary station. The relationship between and may be reversed. Alternatively, instead of adopting such a communication system having a master-slave relationship, a system may be employed in which both send data to the other party when a request to communicate occurs.

  (18) In this embodiment, game balls (game points) are stored on both the gaming machine side and the CU side. However, game balls (game points) are stored only on the game machine side, and the CU side. Then, it may not be stored. On the other hand, the card holding balls (scoring points) are stored only on the CU side, but may also be stored on the gaming machine side. In particular, game balls (game points) are stored only on the gaming machine side, while card holding balls (points) are stored only on the CU side to clarify the division of data storage management. Good.

  (19) The counting display and various notifications performed on the display 54 may be similarly performed on the display 312.

  (20) In CU3, based on the value of the added ball number counter (added ball number) and the value of the subtracted ball number counter (subtracted ball number) transmitted from the P platform side, the stored number of game balls is updated. When the number of game balls stored is subtracted based on the value of the counting ball number counter transmitted from the P platform side, if the value of the number of game balls becomes negative, an error (abnormal) determination is made. Then, error processing may be performed. As a specific example of error processing, error notification is performed by an abnormality notification lamp or the like, or an error notification signal indicating that an error has occurred is transmitted to the hall management computer or hall server 801 (in this case, for hall use). Error notification may be performed by the management computer or hall server 801).

  (21) When a lending operation or a conversion operation (lending operation) from a holding point (holding ball) to a gaming point (game ball) is detected, the gaming points may be counted up one by one. In order to shorten the waiting time of the player, a display may be made so that a plurality of points (for example, 25 points equivalent to 100 yen) are counted up. Conversely, when a game point counting operation is executed, a display may be made so that the points are counted up by a plurality of points. Furthermore, the number of units for counting up and displaying game points or points may be set from a plurality of types. In the setting, it is conceivable to use a touch panel of P or S display devices.

  (22) A touch sensor may be provided on the hitting operation handle, and the counting operation may be invalidated while the touch sensor detects that the player is holding the hitting operation handle. Invalidating the counting operation means detecting the counting operation but not executing the counting operation based on the detection output, or not detecting the counting operation itself. Or, if the player does not invalidate the counting operation only by touching the hitting operation handle, and if the counting operation is disabled if the hitting operation handle is turned to such an extent that the ball firing drive pulse is output. Good.

  In these cases, when a counting operation is detected, a message “Please release handle” may be displayed on the display of the gaming machine or CU. Alternatively, when the counting operation button is displayed as an icon on the touch panel screen, the counting operation button may be grayed out to notify the player that the operation is impossible.

  (23) At least one or all of the ball lending button, the card return button, the replay button, and the counting button may be provided on the gaming machine side, or may be provided on the CU side. Further, it is conceivable that the button is displayed on the display device on the gaming machine side or the CU side described as the touch panel type display device.

  (24) The gaming system according to the present embodiment includes a point use operation means for executing a predetermined point use process using points. Here, the predetermined score use processing includes processing for executing the wagon service, or processing for dividing and sharing the score (held ball) (processing for dividing and transferring the score to another person). It is a concept. The holding point use operation means is, for example, a touch panel. Alternatively, the point use operation means may be a remote controller that is given to a clerk of the game store to instruct the CU or the gaming machine to execute the point use processing.

  (25) In the above-described embodiment, the number of game balls and game points are directly added by the occurrence of a win. Instead, the points are added by the occurrence of a win, and the added points are given. It may be controlled to withdraw and add the number of game balls or game points.

  (26) In the above-described embodiment, when the value is deducted within the range of the valuable value owned by the player (prepaid balance, holding balls, savings) and the corresponding game points are deducted, the value deducted However, instead, for example, it may be controlled to add game points that are smaller by the amount equivalent to the consumption tax with respect to the value actually withdrawn.

  (27) In this embodiment, a key management server is installed in a key management center that is remote from the game arcade. However, the key management server may be installed in the game hall. Thereby, compared with the case where a key management server is installed outside the game hall, it is easier to speed up communication between the CU and the key management server, and the occurrence rate of communication failures can be reduced.

  (28) The CU control unit 323 receives the board security information (including the board authentication key and update information) from the key management server 800 via the hall server 801. However, instead of this, the board security information is transmitted from the key management server 800 to the CU control unit 323 without using the hall server 801 between the key management server 800 and the CU control unit 323. For example, it is conceivable that the key management server 800 and the CU are directly connected to each other, or a relay communication device different from the hall server 801 is provided between the key management server 800 and each CU.

  (29) In the present embodiment, as an example of the game information, the description has been given by taking the ball number, the game ball, the remaining amount of the card, the storage ball, and the number of balls information and the game table information. However, the game information includes other information related to the game on the gaming machine. For example, when a player's favorite character selected or customized by the player can be displayed on variable display means (variable display device) such as the variable display device 278 or the display device 54, information that can specify the character Is also included in the game information. Information on the screen design including the character that matches the player's preference is transmitted to the server at the end of the game in association with the player's card ID and stored, for example, when starting a new game. You may make it download from a server to CU or P stand.

  (30) Check whether there is a change in the number of holding balls or game balls on the CU or P stand, and if the number of held balls or game balls does not change for a predetermined period, notify the CU or P stand of that fact You may do it. Alternatively, a notification signal may be output to an external device (a hall computer, a calling lamp on the P platform). This makes it easier for the store clerk to grasp, for example, a table that has been abandoned while the remaining few balls are left unattended.

  (31) Alternatively, when a player's game ball changes even though the card is not inserted into the CU, the fact may be notified by the CU or P platform. Alternatively, a notification signal may be output to an external device (a hall computer, a calling lamp on the P platform). Thereby, for example, after the game is finished and the card is ejected, the store clerk makes it easy for the store clerk to grasp the stand where the ball caught on the game board wins and the game ball is left as it is paid out.

  (32) In the present embodiment, the CU 3 compares and determines the previous game table information and the latest game table information from the P table 2 with the data stored on its own, and the data on the P table 2 side does not increase illegally. Confirm that the data is correct. If an error determination is made on the CU3 side, such a situation is simply due to the exchange of CU3 (regular data to be compared is not stored in the CU3 after the exchange), and this is based on fraud. Since there is a possibility that it is not a thing, the store clerk confirms the error and cancels the error with a portable terminal device such as a remote control. However, when the CU 3 is replaced with a new one in this way, the CU 3 may not perform the above error determination at all. Alternatively, the above error determination function may not be provided in the CU 3 regardless of whether or not it has been replaced.

  (33) In the present embodiment, a card, which is a recording medium capable of specifying the valuable value owned by the player, is inserted into the card insertion / discharge port 309 at the start of the game, and is removed from the card insertion / discharge port 309 after the game ends. The configuration has been described. However, the present invention is not limited to this, and the card may be placed on the card reading unit at the start of the game and removed from the card reading unit after the game ends. In other words, the recording medium receiving means for receiving the recording medium capable of specifying the valuable value owned by the player may be attached to the recording medium receiving means at the start of the game and removed from the recording medium receiving means after the game ends.

  (34) In the present embodiment, the P stand 2 receives the “store code” and “SC board ID” notified from the security board 325 of the CU 3 when the card is received and communication is restored, and the P stand The configuration has been described in which the “store code” and “SC board ID” held in 2 are determined to match, the recovery process is performed if they match, and the game is prohibited from continuing if they do not match. However, the present invention is not limited to this, and the P stand 2 determines whether the “store code” notified from the security board 325 of the CU 3 matches the “store code” held in the P stand 2 or The “SC board ID” notified from the security board 325 of the CU 3 and the “SC board ID” held in the P platform 2 are determined to match, and if they match, recovery processing is performed and a mismatch is detected. In this case, it may be configured to prohibit the continuation of the game.

  (35) In the present embodiment, even if the key management server 800 transmits a health check request command and does not reach the CU control unit 323, for example, for 10 days, it is determined that the health check request time limit is exceeded, The configuration in which the timed operation function of the CU 3 or the P stand 2 is invalidated has been described. However, the present invention is not limited to this, and the number of days until the timed operation function of the CU 3 or P unit 2 is invalidated is displayed on the display unit 54, or the timed operation function having a plurality of restriction levels is stepwise. It may be invalidated.
