Description

  The present invention relates to a gaming machine having a control board on which an IC chip is mounted via an IC socket.

  Conventionally, in gaming machines such as pachinko machines and slot machines, a method of electronically controlling the progress of a game using an IC chip mounted on a control board via an IC socket has been adopted. In such a gaming machine, it is technically possible to advance a game in an illegal manner in which, for example, jackpots frequently occur, by illegal modification that replaces a regular IC chip with an illegal IC chip. There has been a problem that remodeling acts are unending.

As a countermeasure for preventing the unauthorized modification as described above, a seal seal is affixed to a predetermined part such as an IC chip, a control board, or a board case for housing these (for example, Patent Document 1). . In this way, when trying to make unauthorized modifications, the seal will be broken, or there will remain traces of the seal being peeled off, making it easier to detect unauthorized modifications and, as a result, preventing unauthorized modification. A certain effect can be obtained.
Japanese Patent Application Laid-Open No. 2004-73836

  However, in some cases, instead of a regular seal, an illegal modification that replaces a regular IC chip with an unauthorized IC chip may occur, for example, by applying an elaborately forged seal. It is difficult to sufficiently suppress this.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a gaming machine that can more effectively suppress unauthorized modification of an IC chip.

In order to solve at least a part of the problems described above, the gaming machine of the present invention employs the following configuration. That is,
In a gaming machine having a control board on which an IC chip is mounted via an IC socket,
The IC socket is
A socket body to which the IC chip is mounted;
A cover portion covering at least a part of the upper surface portion of the IC chip,
The socket body has a pair of terminal insertion portions into which a pair of terminal rows formed on both sides of the IC chip are respectively inserted, and a plurality of connection portions for connecting the pair of terminal insertion portions to each other,
When the plurality of connecting portions are viewed between the pair of terminal insertion portions from one end side to the other end side of the terminal insertion portion extending in the column direction of the terminal row, the plurality of connection portions are mutually based on the control board. Are provided at different heights so that the plurality of connecting portions do not overlap each other ,
On one end side of the terminal insertion part, one end part of the cover part is connected in advance to the upper part of one end part of the socket body,
The other end of the terminal insertion portion, after mounting of the IC chip, the other end portion of the cover portion, are inseparably linked to the other end portion of the front Symbol socket body,
When the other end of the cover is connected to the other end of the socket body and the other end of the cover is viewed from the row direction of the terminal row, the other end of the cover and the The connecting portion with the other end portion of the socket body portion is provided at a position lower than the position of the plurality of connecting portions provided between the pair of terminal insertion portions with respect to the control board, and The other end portion of the cover portion is configured in a frame shape so that the space between the IC chip and the control board can be seen from the row direction of the terminal row.

Thus, in the gaming machine of the present invention, the IC socket for mounting the IC chip on the control board is composed of the socket body for mounting the IC chip and the cover portion covering at least a part of the upper surface portion of the IC chip. The socket body and the cover part are integrated. The socket body is composed of a pair of terminal insertion portions into which a pair of terminal rows formed on both sides of the IC chip are inserted, and a plurality of connection portions that connect the pair of terminal insertion portions to each other. The plurality of connecting portions, from the one end side of the terminal insertion portion extending in the direction of the terminal array at the other end, when viewed between a pair of terminal inserting portions do not overlap the plurality of connecting portions to each other In addition, they are provided at different heights with respect to the control board. And on the one end side of the terminal insertion part, the socket main body and the cover part are integrated by rotatably connecting the upper part of the one end part of the socket main body and the one end part of the cover part. Then, with the IC chip mounted on the socket body, the cover part is rotated so as to cover the upper surface part of the IC chip, and the other end part of the cover part and the other end part of the socket body are connected to the terminal insertion part. It is assumed that the other end side is connected inseparably. Furthermore, when the other end portion of the cover portion and the other end portion of the socket body portion are connected, the connection portion between the other end portion of the cover portion and the other end portion of the socket body portion when viewed from the row direction of the terminal row. However, it is provided at a position lower than the position of the plurality of connecting portions provided between the pair of terminal insertion portions with respect to the control board, and the shape of the other end portion of the cover portion is a row of terminal rows. It is configured in a frame shape so that the space between the IC chip and the control board can be seen from the direction. Therefore, one end of the cover part cannot be separated from the socket body unless the cover part or the socket body is broken, that is, the IC chip is removed from the IC socket unless the cover part or the socket body is broken. Will not be able to. According to the gaming machine of the present invention, if the cover part or the socket body is broken when a regular IC chip is replaced with an unauthorized IC chip, the fact of unauthorized modification is easily detected. Exchange can be effectively suppressed. In addition, a plurality of connecting portions, when viewed between the direction of the terminal row of the pair of terminal insertion portions, at different heights control board as a reference, and is provided urchin I nonoverlapping In addition, since the other end of the cover portion is configured in a frame shape so that the gap between the IC chip and the control board can be seen from the row direction of the terminal row, the IC chip and the control board are passed through the frame. It is possible to see through the gap, and it is possible to easily find the biasing part by visual observation. Note that “rotation” in this specification is not limited to a mode in which the cover portion is moved around an axis formed of, for example, a hinge, but the entire cover portion is covered so that the upper surface portion of the IC chip is covered by the cover portion. It is also intended to include embodiments that are deformed in part or in part.

  Further, since the IC socket requires high dimensional accuracy (for example, pin interval), it is extremely difficult to forge the IC socket. As a result, fraud can be more effectively suppressed. For example, even if a seal sticker is used to prevent an illegal act of exchanging an IC chip, if a counterfeit seal sticker is pasted after the IC chip is replaced with an illegal IC chip, the discovery of the fraud Will be difficult. Also, even if the IC chip is housed together with the control board in a board case that cannot be opened unless it is broken, if it is replaced with a counterfeit board case, it will be discovered that a regular IC chip has been replaced with an illegal IC chip. It is difficult. On the other hand, in the gaming machine of the present invention, since the cover part is configured integrally with the IC socket that is difficult to forge, even if an attempt is made to replace a regular IC chip with an unauthorized IC chip, such unauthorized modification It is extremely difficult to conceal this fact with a counterfeit IC socket. Therefore, if an IC chip is illegally exchanged, it can be detected immediately, and as a result, such illegal modification can be more effectively suppressed.

  In addition, since one end of the socket main body and one end of the cover part are rotatably connected and the socket main body and the cover part are integrated in advance, a part for suppressing unauthorized modification is attached to the socket main body ( There is no need to prepare separately from the IC socket), and the work of mounting the IC chip to the control board via the IC socket is not complicated. Therefore, in the gaming machine of the present invention, it is possible to easily suppress the unauthorized modification.

  As a configuration for connecting one end portion of the cover portion to one end portion of the socket body, various modes such as connecting via a hinge are conceivable. However, by forming the cover portion integrally with the socket body, You may connect. If the cover part is formed integrally with the socket body, for example, unlike the case where the cover part is connected to the socket body via a hinge, the number of parts of the IC socket can be suppressed, so that the manufacturing cost of the IC socket can be reduced. Can be suppressed.

  Various configurations are possible for the other end portion of the cover portion to be connected to the other end portion of the socket body in an inseparable manner, but for example, the other end portion of the socket body is inseparably fitted. A possible fitting portion may be provided at the other end of the cover portion. In this way, the other end of the cover part and the other end of the socket body have a complicated shape, which makes it more difficult to forge an IC socket and thus to make an illegal replacement of an IC chip. Become. Further, the other end portion of the cover portion can be connected to the other end portion of the socket body in a non-separable manner by a simple operation such as a fitting operation.

  Various materials are conceivable for forming the socket body and the cover part. For example, the socket body and the cover part may be formed of a transparent resin material. In this way, it is easy to visually inspect whether the IC chip mounted on the IC socket is a genuine product or a counterfeit product, so that it is possible to more effectively suppress unauthorized replacement of the IC chip. it can.

  The power supply board 119 also has a function of relaying transmission / reception of signals performed between the main control board 101 and the medal payout device 137. When a signal to pay out a game medal is output from the main control board 101, the signal is input to the medal payout device 137 via the power supply board 119. As a result, the game medal payout from the medal payout device 137 is performed. Game medals are discharged to the exit 9. The number of game medals paid out is counted by the medal payout device 137, and a game medal payout signal indicating the result is input to the main control board 101 via the power supply board 119. With such a configuration, the CPU 111 can manage the number of game medals stored in the gaming machine 1, the number of game medals paid out to the player, and the like.

B. Overview of control:
The basic flow of the gaming operation in the gaming machine 1 configured as described above is as follows. First, when a game medal is bet before the game starts, the winning lines L1 to L3 are activated according to the number of bets. Next, when the start lever 41 is operated by the player, the game is started by starting the rotation of the rotating cylinder 13, and then when the stop button 43 is operated by the player, the rotating of the rotating cylinder 13 is started. A single game is completed by stopping the game. When such a game is performed once, the gaming machine 1 determines whether or not a predetermined winning symbol combination is aligned on an effective winning line. As a result, when it is determined that a predetermined winning symbol combination is aligned on the effective winning line (winning is established), a game medal is paid out to the player according to the winning mode. In order to realize such a game, in the gaming machine 1 of the present embodiment, the computer including the CPU 111 described above executes the following control processing.

B-1. Control in the general gaming state:
FIG. 4 is a flowchart showing a general game process performed in the gaming machine 1 of the present embodiment. This general game process is a process executed after the gaming machine 1 is powered on and further processes such as ROM sum check and RAM clear are performed.

  As shown in FIG. 4, in the general game process, it is first determined whether or not a game medal is bet (step 10; hereinafter, “step” is abbreviated as “S”), that is, a game medal slot. It is determined whether or not a game medal has been betted by the insertion of a game medal from 33, the operation of the one-sheet insertion button 35 or the three-sheet insertion button 37, or the automatic re-insertion based on the winning of a re-game player (S10). .

  In the process of S10, when it is determined that no game medal is bet (S10: NO), the determination process (S10) is repeated to wait until a game medal is bet. On the other hand, when a game medal is bet, a series of processes described below is started. First, it is determined that a game medal is bet (S10: YES), and as a result, the rotation rotation start process shown in FIG. 5 is executed (S20).

  FIG. 5 is a flowchart showing the rotation rotation starting process performed in the gaming machine 1 of the present embodiment. This rotation rotation starting process is a process for starting the rotation of the rotation cylinder 13 when a predetermined condition is satisfied. In the spinning cylinder rotation start processing of the present embodiment, when two conditions are satisfied, that is, the start lever 41 is turned on, and a predetermined time (4 in the present embodiment is 4) from the start of rotation of the spinning cylinder 13 in the previous game. .1 second) or more, the rotation of the rotating cylinder 13 is started.

  In the rotation rotation starting process, as shown in FIG. 5, it is first determined whether or not the start lever 41 is ON (S210). If it is determined that the start lever 41 is not turned on (S210: NO), the determination processing (S210) is repeated to wait until the start lever 41 is turned on. On the other hand, if it is determined that the start lever 41 is ON (S210: YES), it is determined whether or not a predetermined time has elapsed since the start of rotation of the drum 13 in the previous game (S220).

  In the process of S220, when it is determined that a predetermined time has not elapsed since the start of rotation of the cylinder 13 in the previous game (S220: NO), the determination process (S220) is repeatedly executed for that predetermined period. Wait until has passed. On the other hand, if it is determined that a predetermined time has elapsed since the start of rotation of the drum 13 in the previous game (S220: YES), the main control board 101 outputs a drive signal to the stepping motors 133L to 133R. The body 13 starts to rotate (S230), and then returns to the general game process shown in FIG.

  As shown in FIG. 4, in the general game process, following the spinning rotation start process (S20), the lottery process during the general game shown in FIG. 6 is performed (S30). FIG. 6 is a flowchart showing a lottery process during a general game performed in the gaming machine 1 of the present embodiment. This general game lottery process is a process of performing an internal lottery process (hereinafter referred to as “internal lottery”) by using the lottery table shown in FIG. 7. That is, by acquiring one random number that can take a value in the range of [00001] to [16000] and referring to the lottery table of FIG. 7 based on the acquired random number value, Role) Select one of “Lose” or “Lose”. Note that in a spinning-type game machine, winning a winning combination is not established (determined) just by winning a predetermined combination (hereinafter referred to as “internal winning”) by internal lottery using a lottery table. In order for a winning to be established, it is necessary to stop display in a state where the symbol combinations corresponding to the internal winning combination are aligned on the active line.

  FIG. 7 is an explanatory diagram showing a lottery table used in the lottery process during a general game. As shown in FIG. 7, the lottery tables used in the general game lottery process include a “general game lottery table” and an “internal winning lottery table”. Each of these lottery tables is a table that stores a correspondence relationship between a random value and a combination (or loss). For example, in the “general game lottery table”, “tin tint” is associated with random numbers in the range of “2521 to 2574”.

  Since the correspondence between the random number value and the combination is determined for each lottery table in this way, the winning probability of each combination is set to the value enclosed in parentheses for each lottery table in FIG. become. For this reason, the winning probability is different between the case where the internal lottery is performed using one lottery table and the case where the internal lottery is performed using another lottery table. For example, in the “general game lottery table”, as described above, a “tin tint” is associated with random numbers in the range of “2521 to 2574”. In the “lottery table”, “tin tins” are associated with random numbers in the range of “3121 to 3620”. For this reason, when the internal lottery is performed using the “general game lottery table”, the winning probability of “Snin Minoru” is “50/16000”. In the case of performing an internal lottery using the “table”, the winning probability of the “tin small part” is “500/16000”.

  The reason why the winning probabilities are different for each lottery table in this way is to change the winning probabilities for a predetermined combination according to the gaming state of the gaming machine 1 by switching the lottery table used for the lottery process. is there. In this embodiment, as will be described below, the lottery table is switched according to the difference in the gaming state such as whether the BB combination or the RB combination is being won internally (described later). Change the winning probability.

  Therefore, in the general game lottery process, as shown in FIG. 6, it is first determined whether the big bonus combination (BB combination) or the regular bonus combination (RB combination) is being won internally (S320). “Internally winning” means that an internal winning was made in a game played in the past, but the symbol combination corresponding to the role won internally is not yet available on the active line, so the internal winning state is It means that it has been carried over to the game. For example, even if the BB role was won internally in the previous game, if the symbol combination corresponding to this BB role is not aligned on the active line, the state where the BB role was won internally will be carried over to the current game. It becomes. In addition, for the small combination and re-playing combination, the internal winning state is not carried over.

  If it is not the state in which the BB combination or RB combination is won internally (internal winning) (S320: NO), an internal lottery is performed based on the “general game lottery table” shown in FIG. 7 (S330). That is, by acquiring one random number that can take the values of [00001] to [16000], and referring to the “general game lottery table” based on the acquired random number value, various winning modes (role) Or any one of the loses. In this process, for example, when a random number having a value of [2550] is acquired, “tin tint” is selected (internal winning).

  As described above, when the internal lottery is performed based on the “general game lottery table” (S330), the process returns to the general game process shown in FIG. On the other hand, if it is determined in the process of S320 that the BB combination or RB combination is in an internal winning state (S320: YES), a lottery is performed based on the “internal winning lottery table” (S340). Returning to the general game process shown in FIG.

  The lottery process during the general game is performed as described above, but as shown in FIG. 7, the “internal winning lottery table” used in this process is compared with the “general game lottery table”. The winning probabilities for the small role, replaying role, etc. are set high. In other words, when the BB role or RB role is being won internally, the winning probability of the small role, re-playing role, etc. will be higher than the normal general gaming state until winning of the BB role or RB role is established. ing.

  As described above, even if a winning combination is won internally, the winning combination of the winning combination is not established. In order to establish a winning combination for an internal winning combination in the general game of this embodiment, a combination of symbols corresponding to the internal winning combination needs to be stopped and displayed on the active line. FIG. 8 is an explanatory diagram showing combinations of symbols to be stopped and displayed on the active line in order to establish each winning in the general gaming state. In FIG. 8, the number of game medals to be paid out when each winning is established is also displayed.

  For example, in order to establish the “BB role” winning combination, as shown in FIG. 8, a combination of symbols “7-7-7” or “volcano-volcano-volcano” is aligned on the effective line. Thus, the first cylinder 13L to the third cylinder 13R need to be stopped. Further, in order to establish the “tin tint”, the first cylinder 13L to the third cylinder 13R are arranged so that the symbol combination “tin-tin-tin” is aligned on the effective line. I need to stop.

  Therefore, in the general game process shown in FIG. 4, when the lottery process in the general game is finished, the spinning rotation stop process shown in FIG. 9 is executed to reflect the lottery result (S40). FIG. 9 is a flowchart showing the rotation rotation stopping process performed in the gaming machine 1 of the present embodiment. This spinning cylinder rotation stopping process is a process of stopping the rotation of the spinning cylinder 13 when a predetermined condition is satisfied. In the rotation rotation stop processing of the present embodiment, when the stop button 43 is turned on within a predetermined time (30 seconds in this embodiment) after the rotation of the rotation cylinder 13 is started and the rotation speed becomes constant. Alternatively, the rotation of the rotating drum 13 is stopped when a predetermined time (30 seconds in the present embodiment) elapses after the rotation speed of the rotating drum 13 is started and the rotation speed becomes constant.

  Therefore, in the rotation rotation stopping process, as shown in FIG. 9, it is first determined whether or not the stop button 43 is turned on (S410). In the process of S410, when it is determined that the stop button 43 is not turned on (S410: NO), it is determined whether or not a predetermined time has elapsed since the rotation speed of the rotating cylinder 13 becomes constant ( S420). As a result, when it is determined that the predetermined time has elapsed since the rotation speed of the rotating cylinder 13 becomes constant (S420: YES), the first rotating cylinder 13L, the second rotating cylinder 13C, and the third rotating cylinder 13R. The stop position (stop angle) is determined (S430). Then, the first cylinder 13L, the second cylinder 13C, and the third cylinder 13R are sequentially stopped at the determined stop position (S440). On the other hand, in the process of S420, when it is determined that the predetermined time has not elapsed since the rotation speed of the rotating cylinder 13 becomes constant (S420: NO), the process of S410 is performed again for a predetermined time. Wait until has passed.

  In the process of S410, when it is determined that any of the stop buttons 43 has been turned on (S410: YES), the stop position of the rotating drum 13 corresponding to the stop button 43 that has been turned on is determined (S430). ). The stop position is determined based on the operation timing of the stop button 43 and the result of the internal lottery. When the stop position of the rotating cylinder 13 is determined, the rotating cylinder 13 is stopped at the stop position (S440).

  If the predetermined rotating cylinder 13 is stopped in the process of S440, it is next determined whether or not the rotation of all the rotating cylinders 13 is stopped (S450). As a result, when it is determined that the rotation of all the cylinders 13 has stopped (S450: YES), the process returns to the general game process shown in FIG. On the other hand, if it is not determined that the rotation of all the cylinders 13 has been stopped as a result of the process of S450 (S450: NO), the process returns to the process of S410, and it is determined whether or not the stop button 43 is turned on. To do. Thereafter, when it is determined that the rotation of all the cylinders 13 has stopped (S450: YES), the process returns to the general game process shown in FIG.

  As shown in FIG. 4, in the general game process, after returning from the rotating rotation stop process, it is next determined whether or not a winning combination for any of the winning combinations has been established (S50). The determination as to whether or not a winning is achieved is made by determining whether or not the combination of symbols corresponding to the winning combination (see FIG. 8) is stopped and displayed on the active line. . As a result, if it is determined that no winning combination has been established (S50: NO), the process returns to S10 and waits until a game medal is bet again. When it is confirmed that a bet is made (S10: YES), the above-described series of processing is executed again. On the other hand, if it is determined that a winning combination is established (S50: YES), the process of S60 is executed.

  In the process of S60, it is determined whether or not the winning combination is a re-playing combination. As a result, when it is determined that the winning combination is a re-game player (S60: YES), automatic re-insertion (the same number of game medals as the number used in the current game is automatically bet). (S70), the process returns to S10 and waits until a game medal is bet again. When it is confirmed that a bet is made (S10: YES), the above-described series of processing is executed again.

  On the other hand, if it is determined that the winning combination is not a re-game player as a result of the process of S60 (S60: NO), a medal payout process is executed (S80). In the medal payout process, the number of game medals (see FIG. 8) corresponding to the winning combination is paid out to the player. In the gaming machine 1 of the present embodiment, the gaming medals paid out to the player by winning a prize are temporarily stored in the gaming machine 1.

  Once the medal payout process (S80) is performed, it is next determined whether or not the winning combination is an RB winning combination (S90). In this process, when it is determined that the winning combination is the RB combination (S90: YES), the regular bonus game process shown in FIG. 10 is executed (S100), and then the process returns to S10. Wait until a game medal is bet again. When it is confirmed that a bet is made (S10: YES), the above-described series of processing is executed again. The regular bonus game process will be described later with reference to FIG.

  When it is determined that the winning combination is not the RB combination (S90: NO), it is subsequently determined whether the winning combination is the BB combination (S110). As a result, if it is determined that the winning combination is the BB combination (S110: YES), the big bonus game process shown in FIG. 12 is executed (S120), and then the process returns to S10 and the game is played again. Wait until a medal is bet. When it is confirmed that a bet is made (S10: YES), the above-described series of processing is executed again. The big bonus game process will be described later with reference to FIG. On the other hand, if it is determined that the winning combination is not the BB combination (S110: NO), the process returns to S10 without shifting to the process of S120, and waits until a game medal is bet again.

B-2. Control in regular bonus gaming state:
FIG. 10 is a flowchart showing a regular bonus game process (S100) performed in the gaming machine 1 of the present embodiment. As described above, when a winning combination of RB combination is established, this regular bonus game process (RB game process) is executed. Note that the regular bonus game (RB game) is a game that is played after the RB game process is started after the RB winning combination is established and until the RB game process is completed. In this RB game, (For example, a combination in which a combination of symbols that cannot be won during a general game is a winning combination, or a combination in which such a combination of symbols and a combination that is a winning combination in a general game is a winning combination) Win with probability.

  As shown in FIG. 10, when the RB game process is started, it is first determined whether or not a game medal is bet (S510). This process is the same as the process of S10 in the general game process. In this process, if it is determined that a game medal has been bet (S510), a rotating rotation start process is executed (S520). Since this process is the same as the turning rotation start process (see FIG. 5) performed in the general game process, the description thereof is omitted here.

  When the spinning rotation start process is completed, a regular bonus lottery process (RB lottery process) is executed (S530). In the RB lottery process, an internal lottery is performed using a lottery table (not shown) for RB games.

  When the RB lottery process is completed, a spinning cylinder rotation stop process is executed (S540). Since this process is the same as the spinning cylinder rotation stop process (see FIG. 9) performed in the general game process, the description thereof is omitted here.

  When all the spinning cylinders 13 are stopped in the spinning cylinder rotation stop process of S540, it is next determined whether or not any winning combination has been established (S550). Whether or not a winning has been established is determined by determining whether or not the symbol combinations shown in FIG. 11 are stopped and displayed in a state where they are aligned on the active line, corresponding to the winning combination. As a result of the process of S550, when it is determined that a winning of any combination is established (S550: YES), a predetermined number (see FIG. 11) of game medals is paid out to the player (S560), and then S570 Transition to processing. On the other hand, if it is determined that no winning combination has been established (S550: NO), the process proceeds to S570 without paying out game medals. FIG. 11 is an explanatory diagram showing the award symbol combination and the number of game medals paid out in the RB gaming state.

  In the process of S570, it is determined whether or not to end the RB game process. For example, when the number of games performed in the currently executed RB game process reaches a predetermined number (12 in this embodiment), or the number of winnings established in the currently executed RB game process is the predetermined number of times. It is determined that the RB game process is to be ended when the number of times reaches (in this example, 8 times). As a result of such processing, when it is determined that the RB game process is to be ended (S570: YES), the process returns to the general game process shown in FIG. On the other hand, when it is determined that the predetermined termination condition is not satisfied and the RB game process is not terminated (S570: NO), the process returns to S510.

B-3. Control in Big Bonus gaming state:
FIG. 12 is a flowchart showing the big bonus game process (S120) performed in the gaming machine 1 of the present embodiment. As described above, when a winning combination of BB combination is established, this big bonus game process (BB game process) is executed. The big bonus game (BB game) refers to a game that is performed after the BB game process is started after the BB winning combination is established and until the BB game process is completed.

  As shown in FIG. 12, in the BB game process, first, it is determined whether or not a game medal is bet (S620). This process is the same as the process of S10 in the general game process. In this process, if it is determined that a game medal has been bet (S620: YES), a rotation rotation start process is executed (S630). Since this process is also the same as the rotating cylinder rotation start process (see FIG. 5) performed in the general game process, the description thereof is omitted here.

  When the rotation rotation starting process of S630 is completed, a lottery process during the BB game is executed (S640). This BB game lottery process is a process of performing an internal lottery using the big bonus game lottery table shown in FIG.

  FIG. 13 is an explanatory diagram showing a lottery table (BB game lottery table) used in the BB game lottery process. This BB game lottery table is a table that stores the correspondence between random values and winning combinations (or loses). The numerical values shown in parentheses in FIG. 13 are the winning probabilities of the respective roles. As is clear from the BB gaming lottery table shown in FIG. 13, during the BB game, a re-game player is not won.

  In the BB game process shown in FIG. 12, when returning from the above-mentioned lottery process during the BB game (S640), the rotation rotation stop process is subsequently performed (S650). Since this process is the same as the spinning cylinder rotation stop process (see FIG. 9) executed in the general game process of FIG. 4, the description thereof is omitted here.

  If all the spinning cylinders 13 are stopped in the spinning cylinder rotation stop process of S650, it is next determined whether or not any winning combination has been established (S660). Whether or not a winning has been established is determined by determining whether or not the symbol combinations shown in FIG. 14 are stopped and displayed in a state where they are aligned on the active line, corresponding to the winning combination. FIG. 14 is an explanatory diagram showing a winning symbol combination and a payout number of game medals in a big bonus (BB) game state.

  As a result of the process of S660, when it is determined that a winning combination of any winning combination has been established (S660: YES), the number of game medals corresponding to the winning winning combination (see FIG. 14) is paid out to the player ( After that, the process proceeds to S680. On the other hand, as a result of the process of S660, if it is determined that no winning combination has been established (S660: NO), the process proceeds to S680 without paying out game medals.

  In the process of S680, it is determined whether or not the winning combination is an RB winning combination. As a result, when the winning combination is the RB combination (S680: YES), the RB game process is executed (S690), and then the process proceeds to S700. Note that winning in the RB combination in the BB gaming state is generally called jack-in winning or jack-in. Since the contents of the RB game process in the BB game state are the same as the RB game process called from the general game process (see FIG. 10), the description thereof is omitted here. On the other hand, in the process of S680, when it is determined that the winning combination is not the RB combination (S680: NO), the process proceeds to S700 without executing the RB game process.

  If it is determined as a result of the process of S660 that no winning combination has been established (S660: NO), the process proceeds to S700 without performing the processes of S670 to S690.

  In the process of S700, it is determined whether or not the BB game process end condition is satisfied. This determination is made based on the number of game medals paid out to the player during the BB period, the number of RB game processes executed during the BB period, and the like. For example, when the number of game medals paid out to the player during the BB period reaches an upper limit number (for example, 465), or the number of RB game processes performed during the BB period is a predetermined number ( For example, when it reaches three times, it is determined that the BB game process end condition is satisfied.

  As a result of the process of S700, when it is not determined that the BB game process end condition is satisfied (S700: NO), the process returns to S620. On the other hand, when it is determined that the BB game process end condition is satisfied (S700: YES), the process returns to the general game process shown in FIG.

C. IC socket configuration:
As described above, the operation of the gaming machine 1 according to the present embodiment is controlled by an IC chip (for example, the CPU 111, the ROM 113, or the like) mounted on the control board (for example, the main control board 101). The regular IC chip is set so that proper operation is performed in the gaming machine 1. However, if the IC chip is illegally modified to be exchanged for an illegal one, for example, winning of a big bonus frequently occurs. There is also a possibility that the gaming machine 1 operates in an unauthorized manner. Therefore, in this embodiment, such an illegal modification can be more effectively suppressed by adopting a configuration as described below in an IC socket for mounting an IC chip on a control board. Hereinafter, the configuration of the IC socket employed in this embodiment will be described.

  FIG. 15 is an explanatory diagram showing a state in which the IC chip 700 is mounted on the control board 800 via the IC socket 600 of this embodiment. In the present embodiment, in order to strengthen the suppression of illegal modification of the IC chip, the IC chip 700 is a chip in which a unique IC is written. As shown in the figure, the IC socket 600 includes a socket main body 602 to which the IC chip 700 is mounted, a cover portion 604 for preventing the IC chip 700 from being illegally removed from the socket main body 602, and the like. . Terminals 702 extending downward are arranged in rows on the opposite side surfaces of the IC chip 700, and the IC chip 700 is attached to the socket body 602 via the terminals 702. The cover portion 604 covers a part of the upper surface portion of the IC chip 700, thereby preventing the IC chip 700 from being removed from the IC socket 600.

  FIG. 16 is an explanatory diagram showing the overall configuration of the IC socket 600 of this embodiment. An insertion hole 606 into which the terminal 702 of the IC chip 700 is inserted is provided in the upper surface portion of the socket main body 602 on which the IC chip 700 is placed, and the lower surface portion of the socket main body 602 is correspondingly provided. The connection pins 607 to be soldered to the control board 800 are projected. The insertion hole 606 is connected to the terminal 702 of the IC chip 700 to ensure electrical connection, and the connection pin 607 is accurately connected to the circuit layout of the control board 800 with high accuracy. 602. Therefore, the IC chip 700 can be reliably mounted on the control board 800 via the IC socket 600. In turn, high technology is required to manufacture the IC socket 600.

  The cover portion 604 covering the upper surface of the IC chip 700 is formed integrally with the socket body 602 by a resin material, and has a shape extending from one end portion of the socket body 602 toward the other end portion. One end portion of the cover portion 604 formed in this way is in a state of being connected in advance to one end portion of the socket main body 602 via a cover support portion 608 provided on the upper surface portion of the socket main body 602. The cover portion 604 is supported by the cover support portion 608 via a flexible bent portion 609, and thus can rotate around the bent portion 609. A transparent resin is used as a resin material for integrally molding the socket body 602 and the cover portion 604.

  The cover portion 604 is preliminarily coupled to the socket main body 602 at one end portion as described above, while initially separated from the socket main body 602 at the other end portion. However, the structure of the other end of the cover 604 is such that the IC chip 700 can be coupled to the other end of the socket body 602 after the IC chip 700 is mounted on the socket body 602. That is, the other end portion of the cover portion 604 is provided with a fitting convex portion 610 that can be fitted to the other end portion of the socket body 602, while the other end portion of the socket body 602 is fitted. A fitting recess 612 that can be fitted to the mating projection 610 is provided. As will be described later, the fitting convex portion 610 and the fitting concave portion 612 are configured such that once they are coupled, they cannot be separated. Therefore, the IC chip 700 is removed from the IC socket 600 by covering the upper surface portion of the IC chip 700 attached to the socket body 602 with the cover portion 604 and further fitting the fitting convex portion 610 into the fitting concave portion 612. You can prevent that.

  FIG. 17 is an explanatory diagram showing a state in which removal of the IC chip 700 from the IC socket 600 is prevented by covering a part of the upper surface portion of the IC chip 700 with the cover portion 604. In order to prevent the IC chip 700 from being removed, as shown in FIG. 5A, the cover 604 may be rotated so that the fitting convex portion 610 is fitted into the fitting concave portion 612. As shown in FIG. 5B, when the fitting convex portion 610 is fitted into the fitting concave portion 612, the upper surface portion of the IC chip 700 is covered with the cover portion 604. It is possible to prevent 700 from being removed from the IC socket 600. Note that it is preferable that the cover portion 604 is in close contact with the upper surface portion of the IC chip 700 because unauthorized removal of the IC chip 700 can be prevented more reliably.

  18A is a cross-sectional view taken along the line AA in FIG. 17B, and the fitting convex portion 610 provided at the other end of the cover portion 604 is in relation to the fitting concave portion 612 of the socket body 602. FIG. It shows a state where it is inserted so that it cannot be detached (separated). FIG. 18B is a cross-sectional view individually showing cross-sectional shapes of the fitting convex portion 610 and the fitting concave portion 612. As shown in FIG. 18 (b), return portions 610a project from the left and right side surfaces of the fitting convex portion 610, while on the inner side surfaces of the fitting concave portion 612 facing each other, An engaging portion 612a that engages with the return portion 610a from the rear end side in the insertion direction of the fitting convex portion 610 is formed. The engaging surface where the return portion 610a and the engaging portion 612a engage with each other is set to be substantially perpendicular to the insertion direction of the fitting convex portion 610. Therefore, as shown in FIG. 18A, when the fitting convex portion 610 is inserted into the fitting concave portion 612, the fitting convex portion 610 and the peripheral portion of the fitting concave portion 612 are fitted from the fitting concave portion 612. The convex portion 610 cannot be removed.

  As described above, in the IC socket 600 of this embodiment, one end portion of the cover portion 604 that covers at least a part of the upper surface portion of the IC socket 600 is connected in advance to one end portion of the socket body 602. Yes. Then, after the IC chip 700 is mounted on the socket body 602, the other end portion of the cover portion 604 is connected to the other end portion of the socket body 602 in an inseparable manner. Therefore, the IC chip 700 cannot be removed from the IC socket 600 unless the cover portion 604 or the socket body 602 is broken. If the cover part 604 or the socket body 602 is broken when the regular IC chip 700 is replaced with an unauthorized IC chip, the fact of unauthorized modification is easily detected. Unauthorized replacement of the IC chip 700 can be effectively suppressed.

  In particular, since the IC socket 600 requires high dimensional accuracy (for example, the interval between the insertion holes 606 and the connection pins 607), it is extremely difficult to forge the IC socket 600. In the gaming machine 1 of the present embodiment, since the cover portion 604 is integrally formed with the IC socket 600 that is difficult to forge, even if an attempt is made to replace the regular IC chip 700 with an unauthorized IC chip, It is extremely difficult to conceal the fact of tampering with counterfeit IC sockets. Therefore, even if the IC chip 700 is illegally exchanged, it can be detected immediately, so that unauthorized modification can be more effectively suppressed.

  Further, as described above, since one end of the cover 604 is connected in advance to one end of the socket body 602, unauthorized modification is prevented when the IC chip 700 is mounted on the control board 800 via the IC socket 600. There is no need to provide a separate part for this purpose. Therefore, it is possible to easily take measures for preventing unauthorized modification.

  In addition, since the cover portion 604 is formed integrally with the socket body 602, the number of components constituting the IC socket 600 is suppressed unlike when the cover portion is assembled to the socket body via a hinge, for example. Can do. Therefore, the manufacturing cost of the IC socket 600 can be suppressed, which is preferable.

  Further, as described above, when the fitting convex portion 610 is inserted into the fitting concave portion 612, the other end portion of the cover portion 604 can be connected to the other end portion of the socket body 602. Thus, in the gaming machine 1 of the present embodiment, the other end portion of the cover portion 604 can be connected to the other end portion of the socket body 602 in a non-separable manner by a relatively simple operation called a fitting operation. it can.

  In addition, since the fitting convex portion 610 and the fitting concave portion 612 have complicated shapes, it becomes possible to make it more difficult to forge the IC socket 600 and further to illegally replace the IC chip 700. The effect of preventing unauthorized modification can be enhanced.

  Further, since the socket body 602 and the cover portion 604 are formed of a transparent resin material, it is easy to visually inspect whether the IC chip 700 mounted on the IC socket 600 is a genuine product or a counterfeit product. can do. Therefore, unauthorized replacement of the IC chip 700 can be more effectively suppressed.

C-1. First modification:
In the IC socket 600 according to the above embodiment, as shown in FIG. 18, the return portion 610 a and the engaging portion 612 a for preventing the fitting convex portion 610 from being removed from the fitting concave portion 612 are only one stage. Is provided. However, the present invention is not limited to this, and the return portion 610a and the engaging portion 612a may be provided in a plurality of stages along the insertion direction of the fitting convex portion 610.

  FIG. 19 is an explanatory diagram showing a state in which the return portion 610a and the engaging portion 612a are provided in a plurality of stages (two stages in this modification) along the insertion direction of the fitting convex portion 610. Thus, if the return portion 610a and the engaging portion 612a are provided in a plurality of stages along the insertion direction of the fitting convex portion 610, the fitting convex portion 610 can be more reliably removed from the fitting concave portion 612. can do.

C-2. Second modification:
As shown in FIG. 16, the socket body 602 has a pair of long terminal insertion portions 614 in which insertion holes 606 and connection pins 607 are arranged, and this set of terminal insertion portions. A plurality of connecting portions 616 connecting the 614 to each other are provided. In the above embodiment, as shown in FIG. 16, these connecting portions 616 are provided at the same height position so as to be in close contact with the plate surface of the control board 800. The configuration of the socket body 602 is not limited to this, and for example, a mode (second modified example) as described below may be adopted.

  FIG. 20 is an explanatory diagram showing the overall configuration of the IC socket 600 according to the second modification. As shown in the drawing, in the IC socket 600 of the second modified example, the height positions of the connecting portions 616 are set to be different from each other. As a result, a terminal is inserted between the IC chip 700 and the control board 800. When viewed from one end side to the other end side of the portion 614, the plurality of connecting portions 616 are configured not to overlap each other. Therefore, in the gaming machine 1 according to the present modification, a visual inspection is easily performed between the IC chip 700 and the control board 800 with the IC chip 700 inserted into the IC socket 600 by the method described below. be able to.

  FIG. 21 is an explanatory diagram showing a method for visually inspecting between the IC chip 700 and the control board 800 in the second modification. As shown in the drawing, even when the unauthorized part X is hidden behind the connecting portion 616 when the gap between the IC chip 700 and the control board 800 is observed from one end side (A direction) of the terminal insertion portion 614, By observing from the opposite side (the other end side of the terminal insertion portion 614: the B direction), the unauthorized component X can be easily found. Even if the unauthorized part Y is hidden behind the connecting portion 616 when observed from the B direction, the unauthorized part Y can be easily found by observing from the opposite A direction. This is because the height positions of the plurality of connecting portions 616 are different from each other. As described above, according to the IC socket 600 of this modified example, it is possible to find an unauthorized part provided between the IC chip 700 and the control board 800 very easily.

  As described above, according to the gaming machine 1 of the present modified example, even if an unauthorized part is provided between the IC chip 700 and the control board 800, it can be easily detected. The action can be further effectively suppressed.

  Since the other end portion of the cover portion 604 is configured in a frame shape (referred to as “frame portion 604b”), visual observation is performed from the other end portion side (B direction) of the terminal insertion portion 614. In addition, the space between the IC chip 700 and the control board 800 can be visually observed through this frame. Further, the frame portion 604b on the other end side of the cover portion 604 is formed so as not to overlap each connecting portion 614 when performing visual observation from the B direction. Therefore, the cover portion 604 does not hinder the visual inspection between the IC chip 700 and the control board 800.
