Description

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

  In game machines such as a ball-type game machine and a revolving game machine, a control board is mounted inside, and a method of controlling the progress of the game by the control board is widely adopted. Various IC chips such as a central processing unit (so-called CPU) or ROM are attached to the control board via IC sockets. This IC socket is generally electrically connected by soldering to a control board.

  In such a gaming machine, since various information related to the game is stored in advance in the IC chip, for example, it is set so that it is rarely generated by replacing the IC chip that is properly mounted with another IC chip. In some cases, fraudulent acts such as frequent occurrence of a gaming state (so-called big hit state) advantageous to a player who is playing. As a measure for preventing such an illegal act, a technique has been proposed in which a regular IC chip is attached and then the IC chip is fixed to the control board by using a band so as to be bound to the control board (Patent Document). 1). According to such a technique, it is difficult to remove the mounted IC chip, which is effective in preventing unauthorized replacement of the IC chip.

Japanese Patent No. 3611149

  However, the proposed technique described above has a problem that it is not possible to completely prevent an illegal act of replacing an IC chip. That is, if the band that binds the IC chip is cut, the regular IC chip is replaced with an unauthorized IC chip, and then the band is rebound with the forged band, the discovery of the fact that the IC chip has been replaced is no longer possible. Have difficulty. For this reason, there has been a problem that fraud cannot be completely prevented.

  The present invention has been made to solve the above-described problems in the prior art, and an object thereof is to provide a technique capable of effectively preventing an illegal act of replacing 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,
A control board having connection holes;
An IC chip that has a terminal and is mounted on the control board via the IC socket by inserting the terminal into the insertion hole;
A binding member for binding the IC socket and the IC chip;
In a gaming machine comprising
The binding member is
A bottom portion located between the connecting portion of the IC socket and the control board;
A band portion covering at least a part of the upper surface portion of the IC chip so that the IC chip cannot be removed from the IC socket;
With
As long as the IC socket is not removed from the control board, the bottom of the binding member cannot be removed from between the connecting part and the control board. Engaging means for engaging the bottom and the IC socket is provided,
When the band portion of the binding member is cut, the bottom portion of the binding member remains engaged by the engaging means between the connecting portion and the control board. It remains as a cutting trace .

  In such a swivel type gaming machine of the present invention, a bundling member for bundling an IC chip so that it cannot be inserted and removed from the IC socket is attached to the control board by the IC socket so as not to be removable.

In this way, it is possible to prevent an illegal act of replacing a regular IC chip with another IC chip for the following reasons. First, in an illegal act of replacing an IC chip, it is necessary to cut a binding member that binds the IC chip and the IC socket in order to remove the mounted IC chip. Even if the binding member is cut, the binding member can not be removed from between the connection portion of the IC socket and the control board, and the bottom portion is engaged with the IC socket by the engaging means. The bottom of the binding member remains on the control board as it is. As a result, it becomes easy to find out the fact that the fraudulent act has been performed, and therefore it is possible to effectively prevent the fraudulent act of replacing the IC chip.

  Even if the binding member is counterfeited, it is necessary to remove the IC socket from the control board to remove the cut binding member in order to replace the IC chip. This means that the IC socket is soldered to the control board. This is extremely difficult. That is, in order for a fraudulent person to replace the IC chip illegally, it is necessary to remove the soldering of the IC socket, thereby making it difficult to execute the fraudulent action. As a result, it is possible to suppress fraud.

  An IC tag may be incorporated in a binding member for binding the IC chip to the IC socket. In this way, since the individual binding members can be identified, of course, it is possible to immediately determine whether the attached binding members are genuine or forged. Become. Further, if the data of the IC tag is read wirelessly, a forged binding member can be found more easily. As a result, even if a forged bundling member is attached instead of the regular bundling member, it can be easily discovered, so that it is possible to more surely prevent an illegal act of replacing the IC chip.

In such a gaming machine , the IC socket has a plurality of the connecting portions,
The engaging means is configured such that when the IC chip and the IC socket are bound by the binding member, a convex portion protruding from the bottom of the binding member is fitted between the plurality of connecting portions, The bottom of the binding member may be engaged with the IC socket .

  In this way, after the IC socket is attached to the control board, a part of the binding member is caught by the terminal insertion part or the connecting part of the IC socket, so that it is impossible to remove the binding member from the control board. Therefore, according to such a configuration, it is possible to easily realize that the bundling member is attached to the control board by the IC socket in a non-detachable manner.

  In the gaming machine described above, support portions may be provided at both ends of the bottom portion of the binding member, and the support portions may be locked with the connection portion of the IC socket.

In this way, after the IC socket is attached to the control board, the projecting part protruding from the bottom is caught by the connecting part of the IC socket, so that it is impossible to remove the binding member from the control board .

  In the gaming machine described above, a viewing portion may be provided on the support portion of the binding member so that the gap between the IC chip and the connection portion of the IC socket can be visually confirmed after binding.

  In this way, if the visual observation part is provided in the support part, it is possible to visually check whether the IC chip mounted on the IC socket is genuine or illegal even after being bound by the binding member. It becomes possible to inspect. In particular, when an individual ID is written on the back surface of the regular IC chip (the surface on the IC socket side), it is only necessary to check the ID, so that the IC chip can be easily inspected. Alternatively, even if an illegal act such as incorporating an unauthorized IC chip on the back side of the regular IC chip is performed, the unauthorized IC chip can be visually observed from the viewing unit. As a result, it is possible to more effectively prevent the act of illegally exchanging IC chips or incorporating illegal IC chips.

  Alternatively, in such a gaming machine, a fitting portion is provided in one of the IC socket and the binding member, and a fitting portion is provided in the other, and the IC is in a state where the fitting portion and the fitting portion are fitted. The socket may be attached to the control board.

  In this way, if the IC socket and the binding member are fitted to each other by providing the fitting portion and the fitting portion, the binding member cannot be removed from the control board after the IC socket is attached to the control board. When the binding member is cut for the purpose of illegal replacement of the IC chip, the fact of the illegal act cannot be concealed unless the IC socket is removed. As a result, it is possible to suppress an illegal act of exchanging the IC chip. Moreover, since it is a comparatively simple structure which only provides a fitting part and a to-be-fitted part, it can be applied easily.

  In addition, about fitting of a fitting part and a to-be-fitted part, a fitting part and a to-be-fitted part are such that a binding member cannot be removed from a control board in the state where IC socket was being fixed to the control board. Is not necessarily fixed firmly to the IC socket.

  Further, it is possible to provide a fitting portion on either one of the connecting portion of the IC socket or the bottom portion of the binding member and provide the fitting portion on the other. In this way, in order to remove the cut binding member, even if an unauthorized person tries to destroy the fitting portion or the fitting portion, the fitting portion or the fitting portion is not attached when the IC socket is attached to the control board. Since it cannot touch a part, it is very difficult to destroy a fitting part and a to-be-fitted part. As described above, since it becomes even more difficult to execute fraud, it is possible to effectively prevent fraud.

An AC voltage of 100 V is supplied to the power supply board 280, and this electric power is converted into a DC voltage of a specified voltage and then supplied to each control board and board.

B. Overview of the game:
In the following, the contents of the control performed in order to advance the game in the rotary type gaming machine 1 having the above-described configuration will be described, but as an preparation, an outline of the game performed in the rotary type gaming machine will be described. Keep it.

  In starting the game, a game medal is inserted from the game medal slot 30 and a medal bet is placed. The number of game medals to bet is usually fixed to one or three. If game medals are stored in advance as credits, it is possible to bet 1 or 3 game medals by pressing the 1-sheet insertion button 32 or the 3-sheet insertion button 34, respectively. is there.

  When a game medal is bet and the start lever 36 is operated, the three spinning cylinders 20a, 20b, and 20c start to rotate. As described above with reference to FIG. 3, a plurality of symbols are drawn on each of the spinning cylinders. Therefore, when the rotating cylinder rotates, these symbols are variably displayed on the display window 20. Further, as described above with reference to FIG. 1, on the front side of the front door 2, three turning stop buttons 38 a, 38 b, 38 c are provided corresponding to the respective turning cylinders. When the rotating cylinder stop buttons 38a, 38b, 38c are pressed while the rotating cylinders 20a, 20b, 20c are rotating, the rotating cylinders corresponding to the pressed buttons stop rotating, and accordingly, the symbols that are displayed in a variable manner are displayed. Stopped display with any of the symbols. In this way, when the rotation of the three spinning cylinders 20a, 20b, and 20c is stopped, one of the symbols is stopped and displayed on each of the spinning cylinders. In the gaming machine 1 of the present embodiment, the size of the display window 20 is set such that three symbols are displayed for each cylinder. After all, when the three spinning cylinders 20a, 20b, and 20c are stopped and displayed, a total of nine symbols are displayed on the display window 20 in three columns in the vertical and horizontal directions. In addition, a plurality of pay lines are set in advance at positions where these nine symbols are displayed.

  FIG. 5 is an explanatory diagram showing a winning line set in the gaming machine 1 of the present embodiment. As shown in the drawing, in the gaming machine 1 of the present embodiment, the upper prize line L1, the middle prize line L2, the lower prize line L3, the diagonally upward winning line L4, and the diagonally downward rightward. A total of five pay lines of the pay line L5 are set. When only one game medal is bet, only the middle pay line L2 is valid, and when three game medals are bet, all five pay lines are valid. When the three spinning cylinders 20a, 20b, and 20c are stopped, some symbol combinations are obtained on the effective winning line. Here, it is assumed that only five types of pay lines are set as shown in FIG. 5, but the present invention is not limited to this. For example, the upper position of the left cylinder 20a and the middle cylinder 20b A prize line connecting the middle position and the upper position of the right cylinder 20c, or a prize line connecting the lower position of the left cylinder 20a, the middle position of the middle cylinder 20b, and the lower position of the right cylinder 20c. It is also possible to set more types of pay lines by adding a non-straight pay line or the like.

  And, if the symbol combinations on the effective winning line are the symbol combinations corresponding to the so-called “pocket” game combination, the winning combination of the small role is established, and depending on the type of the small role A certain number of game medals are paid out.

  In addition to the “small role”, a game role called “re-game role” is also provided. If the symbol combination that is valid on the winning line when the spinning cylinder is stopped is a symbol combination that corresponds to the “re-gamer”, no game medals will be paid out, but a new game medal The right to play a game again without betting is granted. That is, it is possible to play a game once again, assuming that the same number of game medals as the game medals bet when the winning of the re-gamer is established.

  Further, the game combination is provided with a so-called “bonus combination” such as “regular bonus combination (hereinafter referred to as RB combination)” and “big bonus combination (hereinafter referred to as BB combination)”. . If the symbol combination that is valid on the winning line when the three cylinders 20a, 20b, and 20c are stopped is a symbol combination corresponding to the RB combination, a regular bonus game (RB that is advantageous to the player) A gaming state called “gaming” is started. The RB game is a game state in which the type of game combination (the type of symbol combination from which game medals are paid out) is increased and the winning of the increased game combination (increased combination) is established with a high probability compared to the normal game. It is. This RB game ends when a predetermined number of games (for example, 12 games) are played or a predetermined number of times (for example, 8 times of winnings) are won. When the symbol combinations corresponding to the BB combination are prepared, a big bonus game (BB game), which is a game state that is more advantageous for the player than the RB game, is started. The BB game is composed of an introductory game until the winning of the RB role is established, and an RB game executed when the winning of the RB role is established. During the BB game, a predetermined number of games (for example, 465) Until the medal is paid out, the above-mentioned “RB game” can be performed a plurality of times. Therefore, when the BB game is started, the player can acquire a large amount of game medals.

  FIG. 6 is an explanatory diagram showing the types of gaming combinations set in the gaming machine 1 of this embodiment and the symbol combinations that establish the winnings of the gaming combinations in association with each other. As shown in the figure, the symbol combination for establishing the winning combination of the BB role includes a symbol combination in which three symbols called “Red Seven” are arranged, and a symbol combination in which three symbols called “Blue Seven” are arranged. Is set. The symbol combination that establishes the winning combination of the RB role is set to a symbol combination including three symbols called “bars”. The symbol combination for winning the winning combination is a combination of three “tin” symbols, three “watermelon” symbols, or a left cherry 20a symbol “cherry”. Is set to Furthermore, the symbol combination that establishes the re-game is set to a symbol combination in which three symbols of “re-game” are arranged. Further, FIG. 6 also shows a privilege that is given to the player when winning of these game actors is established. In addition, the small part that won the prize with the design of "Suzu" is called "Suzu's small part", and the small part that won the prize with the design of "Watermelon" is "Little part of watermelon" and "Cherry" A small role that has won a prize with the above pattern may be called a “cherry small role”.

  Of course, when the spinning cylinders 20a, 20b, and 20c are stopped, it is not always possible to win any game combination. In this case, after betting one or three game medals again, the next game is played by operating the start lever 36 and rotating the spinning cylinder. In the gaming machine 1 of this embodiment, the game progresses by repeatedly performing such operations.

  The progress of such a game is controlled by the main control board 200. Below, the processing content which the main control board 200 is performing in order to control progress of a game is demonstrated.

C. Overview of control:
FIG. 7 is a flowchart showing the first half of a game control process performed by the main control board 200 for controlling the progress of the game in the gaming machine 1 of the present embodiment. FIG. 8 is a flowchart showing the second half of the game control process performed by the main control board 200 in the gaming machine 1 of this embodiment. This game control process is a process executed after power is turned on to the gaming machine 1 and an initialization process such as a checksum of the ROM mounted on the main control board 200 and the sub control board 220 is further performed. .

  As shown in FIG. 7, when the game control process is started, a game state setting process (step 100. Steps are abbreviated as “S” hereinafter) is first performed. Although details of the game state setting process will be described later, in this process, the following process is roughly performed. In the gaming machine 1 according to the present embodiment, as described above, special game states such as a big bonus game (BB game) and a regular bonus game (RB game) are provided, and it is easy to win game players according to the game state. The types of gamers who win the shells are different. Therefore, the current gaming state is grasped and it is determined whether or not the termination condition is satisfied. If the termination condition is satisfied, the gaming state is terminated and the gaming state is switched. By switching the gaming state in this way, the game progresses while greatly changing the impression of the game.

  Following the game state setting process, the main control board 200 performs a medal insertion confirmation process (S102). In the medal insertion confirmation process, whether or not a game medal has been inserted from the game medal insertion slot 30, or whether or not the one-sheet insertion button 32 or the three-sheet insertion button 34 has been operated when the game medal is stored as credit. To check. As described above, the inserted game medal is detected by the medal sensor built in the medal selector 106, and the detection signal is supplied to the main control board 200. Further, when the various input buttons 32 and 34 are operated, the operation signals are supplied to the main control board 200. The main control board 200 can determine whether or not a game medal is inserted based on these signals. When a game medal is inserted, the game can be started. When the various insertion buttons 32 and 34 are operated, a process of subtracting the inserted number from the stored number of game medals is also performed at the same time.

  If the insertion of the game medal can be confirmed as described above, it is possible to start the game at any time by operating the start lever 36, but before that, it is confirmed whether or not the settlement button 40 has been operated. (S104). That is, even after betting game medals, it is possible to settle the medals including the bet game medals before the start lever 36 is operated and the rotating cylinders 20a, 20b, 20c are rotated. It has become. If the settlement button 40 has been operated (S104: yes), a settlement process is performed to perform a process of paying out game medals stored as credits and inserted game medals (S106). The payout of game medals is performed by outputting a control signal indicating the number of game medals to be paid out from the main control board 200 to the medal payout device 118. When the game medals are paid out in this way, the state returns to the state before the game starts (S100), and the subsequent processing is performed.

  On the other hand, if the settlement button 40 has not been operated (S104: no), it is determined whether or not the start lever 36 has been operated (S108). As described above, when the player operates the start lever 36, the operation signal is supplied to the main control board 200, and the three spinning cylinders 20a, 20b, and 20c rotate to start the game. The main control board 200 can determine whether or not the start lever 36 is operated based on the operation signal of the start lever 36. If the start lever 36 has not been operated (S108: no), it is determined that the player has not yet started the game, so confirming whether or not the settlement button 40 has been operated (S106), Wait until the start lever 36 is operated. On the other hand, when the start lever 36 is operated (S108: yes), the internal lottery process is started (S110).

  In the internal lottery process, a process is performed for determining whether or not any of the game combinations described above with reference to FIG. Even if one of the game actors is won in the lottery, the winning of the game actor is not immediately established, and by operating the rotation stop buttons 38a, 38b, 38c, it corresponds to the winning game actor. If the symbol combinations are not aligned on an effective winning line, a winning combination for a gamer cannot be established. On the other hand, no matter what timing the rotation stop buttons 38a, 38b, 38c are operated, it is not possible to align the corresponding symbol combinations on the winning line, unless they are the winning players in the lottery. ing. In that sense, such a lottery is called an internal lottery because it is a lottery performed internally as a precondition for establishing a combination of symbols and establishing a winning combination for a gamer. In addition, the state of winning the internal lottery is called an internal winning state (or simply, internal winning).

  This internal lottery is performed using a dedicated table called a lottery table, and in this table, a correspondence relationship between a game combination and an internal lottery random number is set. Here, the internal lottery random number is a random number acquired when the main control board 200 receives a start lever operation signal. In the gaming machine 1 according to the present embodiment, the internal lottery random number is 2-byte data and can take a random value in the range of 0 to 65535. The random numbers for lottery can be generated by hardware using a dedicated random number generation circuit mounted on the main control board 200, or generated by software using a random number generation program. Is also possible.

  FIG. 9 is an explanatory diagram conceptually showing a lottery table used during a normal game which is the most common gaming state. As shown in the drawing, a random number value of 0 to 7000 is set for “tin tint”. This means that if the acquired random number value is within this range, the small winning combination of tin will be won internally. Similarly, random numbers 7001 to 7100 are set for “red 7 BB combination”, and 7101 to 7200 random number values are set for “blue 7 BB combination”. In addition, random numbers 7201 to 7300 are set for the “RB combination”, random numbers 7301 to 7500 are set for the “watermelon small combination”, and random numbers 7501 to 7600 are set for the “cherry small combination”. However, random values of 7601 to 20100 are set for the “replaying combination”. Note that no game combination is set in the random numbers 20101 to 65535, and therefore, if the acquired random number is within this range, it is “lost”.

  In the internal lottery process, as described above, it is detected that the start lever 36 has been operated to obtain an internal lottery random number, and by referring to the lottery table, which game player has won the internal winning combination, Alternatively, it is determined whether any game player has not won the game internally. When any game combination is won internally, the winning game combination is set in the internal winning flag. Here, the internal winning flag is a flag used for storing the result of the internal lottery, and is set to a predetermined address of the RAM 203 mounted on the main control board 200.

  FIG. 10 is an explanatory diagram showing the data structure of the address for which the internal winning flag is set. As shown in the drawing, in the gaming machine 1 of the present embodiment, the lower 7 bits of 1-byte data provided at a predetermined address on the RAM 203 are used as the internal winning flag. The first bit in these 7 bits is a bit for storing the internal winning combination for the red BB role, and the next bit is for storing the internal winning combination for the blue seven BB role. The next bit is a bit for storing the internal winning of the RB combination. Similarly, the following four bits are used to store the internal winning combination of the tin small part, the watermelon small part, the cherry small part, and the re-playing part. In the internal lottery process (S110) shown in FIG. 7, an internal lottery random number is acquired, and referring to the lottery table, it is determined whether or not any game player has been won internally, and any game If the winning combination is internal winning, a process of setting “1” to the corresponding bit of the internal winning flag shown in FIG. 10 is performed.

  When the internal lottery process is performed, the main control board 200 subsequently starts the spinning cylinder rotation start process (S112). In the rotation rotation starting process, it is determined whether or not a predetermined condition is satisfied. If the condition is satisfied, a process of rotating the three rotation cylinders 20a, 20b, and 20c is performed. In the rotation rotation start processing of this embodiment, when the start lever 36 is operated and a predetermined time (for example, 4.1 seconds) has elapsed since the rotation of the rotation cylinders 20a, 20b, and 20c was started last time. As the rotation of the rotating cylinder is started, a drive signal is output to the rotating cylinder motors 24a, 24b, and 24c provided in the respective rotating cylinders 20a, 20b, and 20c, so that the three rotating cylinders 20a, 20b, and 20c are output. Rotate.

  When the three spinning cylinders 20a, 20b, and 20c are thus rotated, the main control board 200 performs a process of stopping the rotation of the spinning cylinder (rotating cylinder rotation stopping process) (S114). In this processing, after confirming that the rotational speeds of all the spinning cylinders are stabilized at a predetermined speed, the operation of the spinning cylinder stop button corresponding to each spinning cylinder is validated. When the rotating cylinder stop buttons 38a, 38b, and 38c are operated, the operation signals are supplied to the main control board 200. The main control board 200 detects in which rotation position each turn cylinder was located when each rotation stop button was operated based on whether an operation signal from each turn stop button was received. And based on the result, the stop position about each rotator is determined, and the rotator is stopped at the determined position. When determining the stop position of each of the spinning cylinders, the result of the internal lottery performed previously is referred to. Even if is operated, the stop position of the spinning cylinder is determined so that the symbol combination that establishes the game combination is not stopped and displayed. On the other hand, when an internal winning is made for a certain game player, the stop position of each cylinder is determined so that the symbol combination that establishes the internal winning game player is stopped and displayed unless the timing is not too late. It is like that.

  As described above, when the three cylinders 20a, 20b, and 20c are stopped, the main control board 200 determines whether or not any game player has won a prize (S116). Here, “a winning of a game combination is established” means that the symbol combinations corresponding to the internal winning game combination are displayed together on an effective winning line. As described above, in the gaming machine 1 according to the present embodiment, even if one of the game players is won internally in the internal lottery process (S110), depending on the timing of pressing the rotation stop buttons 38a, 38b, 38c, The symbol combinations corresponding to the game actors are not necessarily aligned on an effective winning line. Therefore, after stopping the rotation of the spinning cylinder, the main control board 200 determines whether or not the winning combination of the game player won in the internal lottery has been established.

  If it is determined that no winning combination has been established (S116: no), the game ends, and the process returns to the top of the game control process of FIG. 7 to perform the game state setting process. (S100 in FIG. 7). In the gaming machine 1 of the present embodiment, when a bonus combination (“BB combination” or “RB combination”) is won in the internal lottery process (S110) described above, the symbol combination corresponding to the valid winning line is stopped. Only when the bonus combination winning is not displayed, the internal winning of the bonus combination is carried over, and the game is performed with the internal winning flag of the bonus combination set after the next game. On the other hand, when other winning combinations (“small role” or “re-playing role”) are won internally, the symbol combination corresponding to the winning combination cannot be stopped and displayed on the effective winning line. The internal winning will be reset without being carried over after the next game.

  On the other hand, if it is determined that a winning combination of any game combination is established (S116: yes), first, it is determined whether or not the winning combination is a re-playing combination (FIG. 8). S118). If the re-game player has been won (S118: yes), the re-game flag is set to ON (S120). Here, the re-game flag is a flag for storing that the re-game player has won a prize. If this re-game flag is set to ON, the number of game medals that have been inserted in the game that won the re-game player will be automatically re-set in the next game medal insertion confirmation process (S102 in FIG. 7). It is thrown in. When the re-game flag is turned on in this way, the process returns to the first game state setting process of the game control process of FIG. 7 (S100), and a new game is started.

  On the other hand, if the winning game combination is not a re-playing game combination (S118: no), it is determined whether or not the winning game combination is the BB combination (S122). As described above with reference to FIG. 6, the BB combination is a game combination in which a winning is established when the “Red Seven” symbol is aligned or the “Blue Seven” symbol is aligned on the effective winning line. . If it is determined that the BB combination has been won (S124: yes), after setting the BB game flag to ON (S124), the game control process returns to the beginning and a new game is started. Here, the BB game flag is a flag indicating whether or not the game state is set to an advantageous game state called the above-described big bonus game (BB game). As described above, the gaming machine 1 of this embodiment is provided with a plurality of gaming states, and the game progresses while switching these gaming states. The current game state is indicated by the state of a dedicated flag called a game state flag. At a predetermined address of the RAM 203 mounted on the main control board 200, a 1-byte area for setting a game state flag is secured.

  FIG. 11 is an explanatory view exemplifying the data structure of an area for 1 byte in which the game state flag is set. In the gaming machine 1 of the present embodiment, the lower 2 bits of 1-byte data at a predetermined address on the RAM 203 are used as the gaming state flag. The first bit of these 2 bits is set in the BB game flag, and when the BB game flag is turned ON (S124), "1" is set in this bit. The re-game flag described above is also set to a predetermined address in the RAM 203 mounted on the main control board 200, similarly to the game state flag. In the gaming machine 1 according to the present embodiment, the one bit higher than the two bits used as the gaming state flag is used as the re-gaming flag, and in S120, a process of setting “1” to this bit is performed.

  When the game state setting process (S100) is started by returning to the beginning of the game control process with the BB game flag set to ON, it is detected that the BB game flag is ON and the game state is BB game. Then, the above-described series of processing is performed. Details of the process of switching the gaming state to the BB game based on the BB game flag in S100 will be described later.

  On the other hand, if the winning game combination is not the BB combination (S122: no), it is determined whether the winning game combination is the RB combination (S126). As shown in FIG. 6, the RB combination is a game combination in which a winning combination is established when three “bar” symbols are arranged on an effective winning line. If it is determined that the RB combination is won (S126: yes), the RB game flag is set to ON (S128). Here, the RB game flag is a flag indicating whether or not the game state is the regular bonus game (RB game) described above. The lower bits of the two bits of the gaming status flag shown in FIG. 11 are set in the RB gaming flag, and when the RB gaming flag is turned ON, “1” is set in this bit. When returning to the beginning of the game control process with the RB game flag set to ON, in the game state setting process (S100), the game state is switched to the RB game, and the following series of processes is performed.

  On the other hand, if it is determined that the winning game combination is not the RB combination (S126: no), since it is not any of the re-game combination, the BB combination, and the RB combination, To be judged. Therefore, a process of paying out the number of game medals corresponding to the winning game combination is performed (S130). In other words, if the winning game is a bell small role, 15 game medals are paid out, if a watermelon small role is paid out, 10 game medals are paid out, and if it is a cherry small role, 2 game medals are paid out. Process to pay out. Such processing is performed by determining the number of game medals to be paid out inside the main control board 200 and then outputting a control signal from the main control board 200 to the medal payout device 118. When the game medals are paid out in this way, the game control process shown in FIGS. 7 and 8 is returned to the beginning, and a new game is started.

  As described above, in the gaming machine 1 of this embodiment, when a game medal is inserted and the start lever 36 is operated, the rotation of the spinning cylinders 20a, 20b, 20c is started, and the spinning cylinder stop buttons 38a, 38b, A game in which a game medal is paid out is repeatedly performed depending on whether or not a winning combination of a game player is established when the crotch is stopped by pressing 38c. Although the basic operation of this game is common, the gaming machine 1 of this embodiment is provided with a plurality of game states, and depending on which game state it is, it is easy to win a game player. By switching the type of game player to win, the impression of the game can be greatly varied. The process for switching the game state is performed in the game state setting process (S100) performed at the head of the game control process shown in FIGS. Hereinafter, the contents of the game state setting process will be described in detail.

C-1. Game state setting process:
FIG. 12 is a flowchart showing the flow of the game state setting process performed by the gaming machine 1 of the present embodiment. When the game state setting process is started, first, the CPU 201 of the main control board 200 refers to the game state flag shown in FIG. 11 and determines whether or not the BB game flag is set to ON (S200). . As described above with reference to FIG. 8, the BB game flag is displayed when it is determined that a winning combination for the BB combination has been established by arranging the symbol combinations corresponding to the BB combination on the effective winning line (see FIG. 8). S122: yes), the flag is set to the ON state.

  If the BB game flag is set to ON (S200: yes), it is then determined whether or not the BB game end condition is satisfied (S202). As described above, in the gaming machine 1 of this embodiment, when the number of game medals paid out during the BB game reaches a predetermined number (for example, 465), the BB game is set to end. . Therefore, it is determined whether or not a predetermined number of game medals have been paid out after the start of the BB game. If the game medals have been paid out, it is determined that the BB game end condition is satisfied (S202: yes), and the BB game is determined. In order to finish the game, the BB game flag is set to OFF (S204). Further, as described above, the BB game is composed of a plurality of RB games, and when the BB game end condition is satisfied, the RB game performed in the BB game is also ended. At the same time, the RB game flag is set to OFF.

  On the other hand, when the BB game flag is set to OFF (S200: no), or when it is determined that the BB game end condition has not yet been established (S202: no), the RB game flag is turned ON. It is determined whether it is set (S206). As described above with reference to FIG. 8, the RB game flag is a flag that is set to an ON state when it is determined that a winning combination of RB has been established (S <b> 126 in FIG. 8: yes).

  If the RB game flag is set to ON (S206: yes), it is next determined whether or not the RB game end condition is satisfied (S208). As described above, the RB game is ended when a predetermined number of games are performed (for example, 12 times) or when a predetermined number of times is won for the winning combination (for example, 8 times). If it is determined that any of the end conditions is satisfied (S208: yes), the RB game flag is set to OFF to end the RB game (S210).

  On the other hand, when the RB game flag is set to OFF (S206: no), or when it is determined that the RB game end condition has not yet been established (S208: no), the RB game flag Is omitted (S210).

  As described above, it is determined whether or not the current gaming state is a bonus game (BB game or RB game), and whether or not the bonus game end condition is satisfied, and the condition is satisfied. If the bonus game has been completed, the lottery table is selected according to the current game state flag setting (S212). As described above, the lottery table is a table that is referred to in the internal lottery process (S110 in FIG. 7), and the correspondence between the random numbers for internal lottery and the game combination is set. In addition, since the probability of winning a game combination internally varies depending on the gaming state, a dedicated lottery table is prepared in advance for each gaming state. In S212, processing for selecting an appropriate lottery table from a plurality of lottery tables is performed according to the current setting of the game state flag.

  For example, if neither the BB game flag nor the RB game flag is set to ON, the game state is a normal game. Accordingly, the lottery table for normal games shown in FIG. 9 is selected.

  On the other hand, when the BB game flag is ON, the lottery table for the BB game is selected so that the game state is BB game. FIG. 13 is an explanatory diagram illustrating a lottery table for BB games used in the gaming machine 1 of this embodiment. Compared with the normal game lottery table shown in FIG. 9, the BB game lottery table in FIG. 13 does not have a random number range for the BB role, and during the BB game, the bonus combination is won. The BB game is prevented from starting again. In addition, the random number range is not set for the re-playing combination, and a random value is set for a special combination called “JACIN” instead. In the gaming machine 1 of the present embodiment, RB gaming is started in the BB game when JACIN is elected internally and three symbols of “re-games” are arranged.

  When the RB game flag is set to ON, the lottery table for RB game is selected in order to set the game state to RB game. In addition, since RB game is performed in BB game, both the RB game flag and the BB game flag may be ON. In this case, too, a lottery table for RB game is selected. FIG. 14 is an explanatory diagram illustrating a lottery table for RB games used in the gaming machine 1 of this embodiment. Compared to the regular game lottery table of FIG. 9, in the RB game lottery table, no random number range is set for the BB role and the RB role, so that the bonus role winning is not established during the RB game. It has become. Further, instead of setting a random number range for the re-playing combination, a wide range of random number values are set for the combination called “JAC”. In the gaming machine 1 according to the present embodiment, a predetermined number (for example, 15) of game medals are paid out when three symbols of “re-playing game” are arranged by winning the JAC internally. Therefore, if the series of processes after the internal lottery process (S110 in FIG. 7) described above is performed with the RB game lottery table selected, a JAC winning can be established with a high probability. Since 15 game medals are paid out for each winning prize, the player can efficiently acquire the game medals.

  As described above, an appropriate lottery table is selected from the three types of lottery tables (FIGS. 9, 13, and 14) based on the current setting of the game state flag (BB game flag, RB game flag). When selected, the game state setting process in FIG. 12 is terminated, and the process returns to the game control process shown in FIGS. In the game control process, the game proceeds by performing a series of processes after the internal lottery process using the lottery table thus selected. The game state is switched depending on which lottery table is selected in the game state setting process, and the types of game combinations that can be won in the internal lottery and the ease of winning the game combination are switched.

  Here, as described above, the progress of the game is controlled by the main control board 200, and IC chips such as a CPU 201 and a ROM 202 are mounted on the main control board 200. The ROM 202 stores in advance a program for controlling the progress of the game or important information about the game such as the lottery table used in the internal lottery process described above. If an illegal act to be exchanged is performed, for example, there is a possibility that the game is performed in an illegal manner in which a big bonus combination (BB combination) that is very advantageous for the player is frequently won internally. In view of these points, in the gaming machine 1 of the present embodiment, even if the gaming machine 1 is replaced with an illegal ROM, the gaming machine 1 can be easily discovered and has the following configuration in order to ensure the fairness of the game. ROM 202 is attached.

D. ROM mounting structure:
FIG. 15 is a perspective view showing a state in which the ROM 202 of this embodiment is attached to the main control board 200. FIG. 16 is an exploded view showing how the ROM 202 is attached to the main control board 200. Hereinafter, a configuration for attaching the ROM 202 to the main control board 200 will be described with reference to these two drawings.

  As shown in FIG. 15, the ROM 202 is attached to the main control board 200 via the IC socket 400. A plurality of connection pins 402 are provided downward on the bottom surface of the IC socket 400 (see FIG. 16). After the connection pins 402 are inserted into the connection holes 210 provided in the main control board 200, the main control board is provided. Soldering is performed from the back side of 200. By doing so, the IC socket 400 is fixed to the main control board 200 and is electrically connected to the main control board 200.

  Further, in the gaming machine 1 of the present embodiment, when the IC socket 400 is fixed to the main control board 200, the IC socket 400 is attached in a state where the binding member 500 is sandwiched between the IC control board 200 and the main control board 200. Yes. As shown in FIG. 16, the binding member 500 is provided with a bottom portion 502, and the IC socket 400 is further provided with a connecting portion 408 for connecting a pair of terminal insertion portions 406 to each other. ing. When the IC socket 400 is fixed to the main control board 200, the bottom 502 is sandwiched between the connecting portion 408 and the main control board 200, and the binding member 500 is fixed to the main control board 200.

  In this way, the ROM 202 is mounted on the IC socket 400 fixed to the main control board 200. As shown in FIG. 16, a terminal 205 extending downward is provided on the side surface of the ROM 202, and this terminal 205 is inserted into the insertion hole 404 provided on the upper surface of the terminal insertion portion 406 of the IC socket 400. insert. Then, the terminal 205 is electrically connected to the main control board 200 via the connection pins 402.

  Next, with the ROM 202 mounted on the IC socket 400, the band portion 504 extending from one end of the binding member 500 is tightened through the insertion hole 508 provided at the other end. As a result, as shown in FIG. 15, the ROM 202 and the IC socket 400 are attached to the main control board 200 while being bound by the binding member 500. The tip of the band portion 504 and the inside of the insertion hole 508 have a structure that cannot be removed once tightened. Further, FIG. 16 shows a state in which the band member 504 protruding from the insertion hole 508 is cut off after the binding member 500 is tightened.

  As described above, the ROM 202 of this embodiment is attached to the main control board 200 while being bound to the IC socket 400 by the binding member 500. Accordingly, since the ROM 202 cannot be removed from the IC socket 400 unless the binding member 500 is cut, it is difficult to replace the regular ROM 202 with an unauthorized ROM.

  Even if the band portion 504 of the bundling member 500 is cut for the purpose of illegally replacing the ROM 202, the gaming machine 1 of the present embodiment can easily find illegal acts for the following reasons. Yes. First, as shown in FIG. 16, the binding member 500 is provided with support portions 506 at both ends of the bottom portion 502 facing upward. When the IC socket 400 is fixed to the main control board 200, the support portion 506 is positioned outside the IC socket 400 (see FIG. 15), and the support portion 506 is caught by the connecting portion 408. Can not be removed. That is, even if the ROM 202 is illegally replaced, the binding member 500 remains in a cut state, so that the fact of the illegal act can be easily found. As a result, it is possible to effectively prevent an illegal act of replacing the ROM 202.

  When the support portion 506 is broken, the binding member 500 can be detached from the main control board 200. However, even in this case, it is extremely difficult to insert the counterfeit binding member (having the same structure as the binding member 500) between the IC socket 400 and the main control board 200 and attach it as it was. It is. That is, in order to attach the forged binding member, it is necessary to remove at least the soldering between the IC socket 400 and the main control board 200. The work of removing this soldering requires labor and time, and is a difficult work for performing an illegal act. After all, it is difficult to attach a forged binding member after destroying the support portion 506, so that it is possible to suppress fraud.

  In addition, if an IC tag is incorporated in the bundling member 500 in advance, even if a forged bundling member is attached instead of the regular bundling member 500, it can be easily identified. It becomes possible to prevent more reliably.

  Further, as shown in FIG. 15, in the gaming machine 1 of the present embodiment, an opening 510 is provided in the support portion 506 of the binding member 500, and the back surface of the ROM 202 (the surface on the IC socket 400 side) is provided. It is visible.

  FIG. 17 is an explanatory diagram showing a state in which the space between the ROM 202 and the IC socket 400 is viewed through the opening 510. The white arrow in the figure represents the viewing direction. As shown in the figure, the opening 510 is provided at a position where it can be seen through between the ROM 202 and the connecting portion 408 of the IC socket 400. For this reason, even after the binding member 500 is tightened, the unique ID written on the back surface of the ROM 202 can be visually checked to determine whether the ROM 202 is genuine. For this reason, it is possible to more effectively prevent an illegal act of replacing the ROM 202.

  In addition, since the space between the ROM 202 and the IC socket 400 can be visually observed by the opening 510 provided in the binding member 500 of the present embodiment, the opening 510 of the present embodiment corresponds to the “viewing portion” of the present invention. Equivalent to. Further, in the gaming machine 1 of the present embodiment, the opening 510 is provided in the binding member 500, but of course, it is not limited to this as long as the back surface of the ROM 202 can be visually observed. For example, the same effect can be obtained by forming the binding member 500 from a transparent material.

E. Modified example:
E-1. First modification:
In the embodiment described above, the support portions 506 are provided upward at both ends of the bottom portion 502 of the binding member 500, and the binding member 500 cannot be removed by being caught by the connecting portion 408. As explained. However, the binding member 500 is not limited to such a shape, and for example, a locking portion may be provided on both sides of the binding member 500. Below, the 1st modification which provided such a latching part is explained.

  FIG. 18 is an exploded view showing a state in which the IC socket 400 and the binding member 500 of the first modified example are fixed to the main control board 200. Similar to the above-described embodiment, the IC socket 400 of the first modified example is attached with the bottom 502 of the binding member 500 sandwiched between the IC socket 400 and the main control board 200. As shown in FIG. 18, locking portions 512 extending in the lateral direction are provided on both sides of the binding member 500. When the IC socket 400 is fixed to the main control board 200, the locking portion 512 is positioned outside the IC socket 400, and even if the binding member 500 is to be removed, the locking portion 512 is not attached to the IC socket 400. The terminal insertion portion 406 is hooked.

  For this reason, similarly to the above-described embodiment, even when the ROM 202 is illegally exchanged, the cut binding member 500 remains, and it becomes easy to find an illegal act. As a result, fraud can be effectively prevented.

E-2. Second modification:
In the embodiment and the first modification described above, the binding member 500 is provided with a portion (support portion 506 or locking portion 512) that is locked to the IC socket when the binding member is to be removed. As explained. However, if the binding member 500 can be attached to the main control board 200 in a non-detachable manner by fixing the IC socket 400 to the main control board 200, the shape of the binding member 500 is not limited to these. Absent. For example, the IC socket 400 may be provided with a protrusion, and the binding member 500 may be provided with an insertion hole. Below, the 2nd modification which employ | adopted such a structure is demonstrated.

  FIG. 19 is an exploded view showing a state in which the IC socket 400 and the binding member 500 of the second modified example are fixed to the main control board 200. Similar to the above-described embodiment and the first modification, the IC socket 400 of the second modification is attached with the binding member 500 sandwiched between the main control board 200 and the IC socket 400. As shown in FIG. 19, the IC socket 400 of the second modified example is provided with a protruding portion 410 extending downward from the connecting portion 408, and the bottom portion 502 of the binding member 500 (with the IC socket 400). An insertion hole 514 is provided in a portion sandwiched between the main control board 200 and the main control board 200. When attaching the IC socket 400 to the main control board 200, the protrusion 410 is inserted into the insertion hole 514 provided in the binding member 500 so that the binding member 500 is fixed to the main control board 200. It has become. A broken line arrow in FIG. 19 represents a state in which the protrusion 410 is inserted into the insertion hole 514. It should be noted that when the IC socket 400 is fixed, the tip of the protrusion 410 comes into contact with the main control board 200. Further, since the protrusion 410 provided in the connecting portion 408 is fitted into the insertion hole 514 of the binding member 500, the protrusion 410 of the second modified example is the “fitting portion” of the present invention. The insertion hole 514 corresponds to the “fitted part” of the present invention.

  As described above, in the gaming machine 1 according to the second modification, the bundling member 500 cannot be removed from the main control board 200 by passing the protrusion 410 through the insertion hole 514. For this reason, as in the above-described embodiment, even if the bundling member 500 is cut and the regular ROM 202 is replaced with an illegal ROM, it becomes easy to find the trace at an early stage. As a result, it is possible to effectively prevent an illegal act of replacing the ROM 202.

  Further, if the binding member 500 of the second modification is formed of a flexible material, the binding member 500 bends according to the size of the IC socket 400 (and the ROM 202), so the band portion 504 and the insertion hole 508 Regardless of the size of the IC socket 400, the binding member 500 can be applied only by adjusting the tightening. Therefore, it is not necessary to prepare the binding member 500 for each size of the IC socket 400, and the binding member 500 can be shared.

  In the above description, the protrusion 410 is provided, but the protrusion 410 may be replaced by the connection pin 402. That is, the width of the binding member 500 is made wider than that of the IC socket 400, and the insertion holes 514 are provided at positions corresponding to the connection pins 402, respectively. Then, when the IC socket 400 is fixed to the main control board 200 after the connection pin 402 is passed through the insertion hole 514, the binding member 500 is fixed to the main control board 200 as in the case where the protrusion 410 is provided. be able to.

E-3. Third modification:
In the second embodiment described above, the protrusion 410 is provided on the IC socket 400 and is inserted into the insertion hole 514 of the binding member 500. However, conversely, it is also possible to provide the binding member 500 with a convex portion for fitting into the IC socket 400. Below, the 3rd modification which provided the convex part in the binding member 500 is demonstrated.

  FIG. 20 is an exploded view showing a state in which the IC socket 400 and the binding member 500 of the third modified example are fixed to the main control board 200. As shown in the figure, in the binding member 500 of the third modified example, a convex portion 516 is provided on the bottom portion 502 (a portion sandwiched between the IC socket 400 and the main control board 200). Then, when the IC socket 400 is fixed to the main control board 200, the convex portion 516 is located between the connecting portion 408 and the connecting portion 408 of the IC socket 400 (hereinafter, this portion is shown) as indicated by broken line arrows in the drawing. And the binding member 500 is fixed to the main control board 200.

  For this reason, as in the above-described embodiments and modifications, even if the ROM 202 is illegally replaced, the fact is easily detected. As a result, fraud can be effectively prevented.

  Here, as long as the convex portion 516 is fitted into the interval portion (between the connecting portion 408 and the connecting portion 408) to such an extent that the binding member 500 cannot be removed from the main control board 200, how will it be? Any shape (or size) may be used. Of course, the convex portion 516 can be formed in advance according to the shape (size) of the interval portion, and by doing so, the binding member 500 can be more reliably fixed. When the IC socket 400 is fixed, the convex portion 516 of the binding member 500 is inserted into the interval portion of the IC socket 400, and therefore the convex portion 516 of the third modification corresponds to the “fitting portion” of the present invention. The spacing portion of the third modification corresponds to the “fitted portion” of the present invention.

  Also, in many IC sockets that are widely used in general, a pair of terminal insertion portions 406 are connected by a plurality of connecting portions 408, and a spacing portion is provided between the connecting portions 408. Therefore, if the convex part 516 is provided in the binding member 500, it can apply easily, without processing an IC socket, and it becomes possible to give the binding member 500 versatility.

  While various embodiments of the present invention have been described above, the present invention is not limited thereto, and is not limited to the wording of each claim unless it departs from the scope described in each claim. Improvements based on the knowledge that a person skilled in the art normally has can also be added as appropriate to the extent that those skilled in the art can easily replace them.

  For example, in the above-described embodiments and modifications, the case where the ROM 202 is attached to the main control board 200 has been described. However, as long as the ROM 202 is attached to the board via an IC socket, the invention is not limited to the ROM. It can also be applied to the mounting of IC chips in general. Further, as long as the IC chip is a substrate mounted via an IC socket, the present invention can be suitably applied not only to the main control substrate 200 but also to various substrates such as the sub control substrate 220 and the door substrate 240.

  Moreover, it is good also as adding the fitting part and to-be-fitted part provided in the 2nd modification or the 3rd modification to the IC socket 400 and the binding member 500 of the Example mentioned above. By doing so, not only the support portion 506 of the binding member 500 is caught by the IC socket 400 but also fixed by the fitting between the fitting portion and the fitted portion, so that the binding member 500 can be attached and detached more firmly. It becomes possible to prevent.
