Abstract

<P>PROBLEM TO BE SOLVED: To provide a game machine which facilitates the discovery of the illegal modification of electronic parts. <P>SOLUTION: In the control board 800, a lattice-like pattern 810 is printed on top of a tally 910 applied on a seal 900 between both and the printing is made using an ink material removable with a chemical agent capable of erasing the tally 910 as well. As a result, after the peeling of the seal 900 off, the tally 910 left on the side of the control board 800 can not be erased without getting the pattern 810 put out on the control board 800 together with the tally 910. Thus, after the replacement of an IC chip 700 with the illegal part on the control board 800, a fake seal 900 and a fake tally 910 may be applied but the mark proving the erasion of the regular tally 910 is left somewhat on the control board 800. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a gaming machine in which the progress of a game is controlled by electronic components.

  Conventionally, a game machine such as a pachinko game machine or a slot machine employs a method of electronically controlling the progress of a game using a control board on which various electronic components such as an IC chip are mounted. In such a gaming machine, it is technically possible to advance a game in an unauthorized manner in which, for example, jackpots frequently occur by unauthorized modification such as replacement of regular electronic components with unauthorized electronic components.

  As a measure to prevent such unauthorized modification, a measure has been proposed in which a seal seal is pasted across the electronic component and the control board, and a seal is applied between the seal seal and the control board. (For example, Patent Document 1). In this way, since the seal that has been peeled off remains when the electronic component is tampered with, the tampering can be detected relatively easily. As a result, a certain effect can be obtained in preventing tampering.

Japanese Patent Laid-Open No. 10-15196

  However, even if such a method is used, there is a problem that it is difficult to find unauthorized modification if the seal seal or the seal is forged. This is because if the seal seal is peeled off and the percent mark remaining on the control board is erased, the electronic component is replaced with an illegal component, and if a forged seal seal and percent mark are applied on the electronic component, it will no longer be illegal modification. This is because it is difficult to identify whether or not the error has occurred. Of course, as described in Patent Document 1, it is possible to make it difficult to erase the mark by engraving the mark by laser processing, but this requires additional equipment investment.

  The present invention has been made in view of these problems, and an object of the present invention is to provide a gaming machine in which it is easier to find unauthorized modification of electronic components. Another object of the present invention is to provide a gaming machine capable of effectively preventing unauthorized modification with a simple configuration.

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 gaming machine in which the progress of the game is controlled by electronic components,
A control board on which the electronic component is mounted;
A sealing seal affixed so as to straddle the control board and the electronic component, and a seal is stamped between the control board and the control board;
The control board is characterized in that a predetermined pattern is formed in the vicinity of a portion where the mark is stamped in a state where at least a part of the mark is deleted when the mark is deleted.

  As described above, the control board of the gaming machine of the present invention has a predetermined pattern formed in the vicinity of the mark provided between the seal and the seal, and at least a part of the pattern is deleted when the mark is deleted. It is formed in the state. Therefore, if an attempt is made to erase the remaining mark on the control board side after the regular seal is peeled off, the pattern on the control board will be deleted together with the mark. For this reason, even after the electronic parts on the control board are replaced with unauthorized parts, even if a forged seal seal or mark is applied, there will be a trace of the legitimate mark off on the control board. Can be easily discovered, and as a result, unauthorized modification can be effectively prevented.

  As the pattern formed in the vicinity of the tally, it is desirable to employ a fine pattern that is difficult to restore, such as a striped pattern, a lattice pattern, or a geometric pattern. This is because the more difficult it is to restore the pattern, the more difficult it is to conceal the illegal modification, so that unauthorized modification can be prevented more effectively.

  Such a pattern can be formed by various methods. For example, the pattern may be formed by printing, and then the pattern can be easily formed. In this case, the pattern printing may be performed simultaneously with a so-called symbol printing process for printing a display such as a board name or an electronic component mounting position, so that the pattern can be formed more easily.

  When the pattern is formed by printing, an ink material that is removed by a chemical (for example, an organic solvent) capable of erasing the markings may be used. By doing so, when the tally is erased using chemicals, at least a part of the pattern is also erased, so that it is possible to easily find out that unauthorized modification has been performed.

  In this case, the ink material used for pattern printing and the ink material used for the marking may have the same non-volatile component contained in the most, so that these ink materials are common. It will be removed by chemicals. Therefore, if an attempt is made to delete the mark using a chemical, at least a part of the pattern is also deleted, so that it is possible to easily find out that unauthorized modification has been performed.

  In such a gaming machine, a pattern may be formed by printing as described above, but a concavo-convex pattern may be formed by configuring the surface of the control board to be concavo-convex. In this case, if a pattern is formed so that the irregularities are smoothed when an attempt is made to erase the regular tally, it is possible to leave a trace where the tally has been removed. In this way, if the pattern formed on the surface of the control board is configured with a concavo-convex pattern, restoration can be made more difficult, so that unauthorized modification can be more effectively prevented.

  In addition, at least a part of the mark may be stamped on the pattern, so that it becomes more difficult to erase only the mark without erasing the pattern. Can be aimed at.

A closing button 37, a settlement button 39, a first stop button 43L, a second stop button 43C, a third stop button 43R, and the like are connected. When these buttons 35, 37, 39, 43 L to 43 R are operated by the player, a signal indicating the operation result is input to the main control board 101 through the central display lamp board 107. In the main control board 101, based on this input signal, the operation state for each button 35, 37, 39, 43L to 43R is determined.

  In addition to the central display lamp board 107, a left display lamp board 125, a right display lamp board 127, a start lever unit 129, a medal selector 131, and the like are also connected.

  The left display lamp board 125 is a board for performing on / off control of the 1 medal line lamp 15a, the 2 medal line lamp 15b, the 3 medal line lamp 15c, and the game start display lamp 17 provided on the left side of the display window 5. It is. Such On / Off control is performed by inputting a predetermined signal from the main control board 101 to the left display lamp board 125 via the central display lamp board 107.

  Further, the right display lamp substrate 127 performs on / off control of the stop display lamp 19 provided on the right side of the display window 5, the re-game lamp 21, the big bonus notification lamps 23a to 23c, the game medal insertion lamp 25, and the like. It is a substrate for. Such On / Off control is performed by inputting a predetermined signal from the main control board 101 to the right display lamp board 127 via the central display lamp board 107.

  The start lever unit 129 includes the aforementioned start lever 41 and a rotating cylinder rotation start sensor substrate (not shown) for detecting the operation of the start lever 41. When the start lever 41 is operated by the player, the operation is detected by the rotation-rotation start sensor board, and a rotation-rotation start signal indicating the detection result is further sent via the central display lamp board 107 to the main control board 101. Is input. With such a configuration, the computer on the main control board 101 can determine the operation state with respect to the start lever 41.

  The medal selector 131 is a device for selecting the game medals inserted from the game medal slot 33 based on the dimensions, and accepting only the game medals that meet the standard dimensions. In the medal selector 131, in addition to the function of selecting such game medals, the medal sensor board (not shown) detects the passage of the inserted game medals, and a blocker (operated by an electromagnetic solenoid (not shown)). A function of returning a game medal without accepting it is also provided. When the passage of a game medal is detected by the medal sensor board, a medal detection signal indicating the detection result is transmitted from the medal selector 131 to the main control board 101 via the central display lamp board 107. With this configuration, the computer on the main control board 101 can determine whether or not a game medal has been inserted from the game medal slot 33.

  In addition to the main control board 101, the stepping motors 133L, 133C, 133R, the rotation sensor boards 135L, 135C, 135R and the like are connected to the rotor board 103.

  The stepping motors 133 </ b> L to 133 </ b> R are motors for rotating / stopping each cylinder 13. These stepping motors 133L to 133R are provided in a number (three in the present embodiment) corresponding to the respective spinning cylinders 13L to 13R, and the shafts of the respective stepping motors 133L to 133R are used as the rotational axes of the corresponding respective spinning cylinders 13. It is used. The rotation / stop operation of these stepping motors 133L to 133R can be controlled by sending a signal from the main control board 101 to the stepping motors 133L to 133R via the rotating board 103. Accordingly, each cylinder 13 can be rotated / stopped by rotating / stopping the stepping motors 133L to 133R with a control signal from the main control board 101.

  The spinning sensor substrates 135L to 135R are for detecting passage of index portions (not shown) provided in each spinning cylinder 13, and the number corresponding to each spinning cylinder 13L to 13R (three in this embodiment). ) Is provided. When the index portion of each of the spinning cylinders 13 passes through the spinning cylinder sensor substrates 135L to 135R, and the passage is detected by each of the spinning cylinder sensor substrates 133L to 133R, a spinning cylinder index signal indicating the detection result is transmitted to the spinning cylinder substrate 103. Via each of the cylinder sensor boards 133L to 133R. For this reason, it is possible to manage the rotation angle of each spinning cylinder 13 (and thus the position of the symbol drawn on the outer peripheral surface of the spinning cylinder 13) by the main control board 101. Since the index portion of each of the spinning cylinders 13 passes through the spinning sensor substrate every time the spinning cylinder 13 makes one revolution, the spinning cylinder index signal is sent to each of the spinning cylinder sensor boards 133L to 133R every time the spinning cylinder 13 makes one revolution. To the main control board 101.

  In addition to the main control board 101, a medal payout device 137 and the like are connected to the power supply board 119. The power supply board 119 supplies power to the spinning board 103, the sub control board 105, the central display lamp board 107, and the like through the main control board 101, and also supplies power to the medal payout device 137.

  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 predetermined winning symbol combinations are aligned on the effective winning line (winning is established), game medals are 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. The regular bonus game (RB game) refers to 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. Sealing structure of electronic parts:
As described above, the gaming machine 1 according to the present embodiment operates on a control board (for example, the main control board 101 and the sub-control board 105) on which various electronic components such as an IC chip such as the CPU 111 and the ROM 113 are mounted. ). For this reason, if such an unauthorized modification of the electronic components is performed, the gaming machine 1 may operate in an unauthorized manner such that, for example, big bonuses are frequently won. Therefore, in this embodiment, the tampering is prevented by adopting a sealing structure as described below. In the following description, the sealing structure of the IC chip mounted on the control board will be described as an example.

  FIG. 15 is an explanatory diagram showing a state in which electronic components such as the capacitor 600 and the IC chip 700 are mounted on the control board 800. As shown in the figure, a seal seal 900 is stuck on the IC chip 700 so as to straddle the control board 800, and removal from the IC socket 750 is prohibited. Further, a split mark 910 is stamped between the seal sticker 900 and the control board 800 attached in this way. Therefore, even if the seal seal 900 is peeled off and the IC chip 700 is illegally replaced, there is a trace that the seal seal 900 is peeled off, such as the shape of the split seal 910 is broken, so that unauthorized modification can be found relatively easily. It is possible to do.

  Further, in the gaming machine 1 of the present embodiment, in order to make it easier to find unauthorized modification, a lattice-like pattern 810 is printed on the surface of the control board 800, and an index 910 is overlapped with the pattern 810. It has been pushed. The ink material used for printing the pattern 810 has the property that the non-volatile component contained most is the same component as the oil-based ink material used for the index 910, so that the index 910 is dissolved by an erasable chemical. ing. Therefore, if the index 910 is erased with a chemical, at least a part of the pattern 810 is erased, so that a trace of unauthorized modification remains, and as a result, it becomes possible to find unauthorized modification more easily.

  The pattern 810 is preferably a fine pattern that is difficult to restore when a part of the pattern 810 is erased. For example, the line width is 0.2 to 0.5 mm and the line interval is 0.5 mm to 1 mm. Is good. However, making the pattern 810 too fine not only makes it difficult to print the pattern, but even if a portion of the pattern is erased and ink is applied to the erased portion, traces of erasure are found. Since it becomes difficult, it is not preferable. The pattern 810 may be a pattern other than a lattice pattern, and may be any pattern that is difficult to restore, such as a striped pattern or a geometric pattern.

  FIG. 16 is a flowchart showing a manufacturing process of the control board 800, and FIG. 17 is an explanatory diagram showing a state in which the above-described pattern 810 is formed in the manufacturing process of the control board 800. In manufacturing the control substrate 800, as shown in FIG. 17A, first, a process of forming the through hole 808 and the wiring pattern portion 824 in the insulating substrate (substrate substrate) 820 is performed. The procedure is described below.

  As shown in FIG. 16, first, after copper foil is bonded to the front and back surfaces of the insulating substrate 820 (S801), "hole drilling" is performed using an NC multi-axis drilling machine or the like (S805). The perforation is made in the insulating substrate 820 at the site where the through hole 808 is formed, the site where the mounting hole for attaching the control board 800 to the case or the like is formed.

  Next, the insulating substrate 820 is subjected to catalyst application and electroless copper plating (S810), and further subjected to electrolytic copper plating (S815), thereby forming a copper plating layer on the copper foil. Then, an etching resist material (for example, a dry film) is mounted on the surface of the insulating substrate 820 on which the copper plating layer is formed, and then exposure and development are performed to form an etching resist film (etching resistant film) on the exposed portion. (S820). However, an etching resist material that forms an etching resist film in a portion that is not exposed may be used. When the etching resist film is formed on the surface of the insulating substrate 820 in this manner, the portion of the copper foil that is not covered with the etching resist film (etching resistant film) is dissolved with an etching solution (S825). By this etching process, only unnecessary portions of the copper foil are dissolved, while necessary portions remain undissolved, so that a wiring pattern portion 824 is formed on the surface of the insulating substrate 820. .

  Since the etching resist film becomes unnecessary after the etching process, the etching resist film is removed using a predetermined chemical to expose the wiring pattern portion 824 and the insulating substrate 820 (S830). Through the above process, through holes 808 and wiring pattern portions 824 are formed in the insulating substrate 820 as shown in FIG.

  When the through hole 808 and the wiring pattern portion 824 are formed in the insulating substrate 820, then, as shown in FIG. 17B, a solder resist layer 830 is formed in a predetermined region of the insulating substrate 820 (S835). . First, the insulating substrate 820 is covered with a solder resist (solder resist) mask, and the solder resist ink is transferred through the solder resist mask to form a solder resist layer 830 on the insulating substrate 820. The solder resist mask is composed of a flat plate with holes, a passage hole portion that constitutes a portion through which the solder resist ink passes, and an island portion that constitutes a portion that does not allow the solder resist ink to pass through (the plate cannot be drilled. A portion having a shape). Therefore, the solder resist layer 830 is formed on the insulating substrate 820 in a region covered with the passage hole portion of the solder resist mask.

  When the solder resist layer 830 is formed on the insulating substrate 820, subsequently, as shown in FIG. 17C, the symbol 832 indicating the mounting position of the electronic component and the above-described pattern 810 are silk-printed. (S840) (S840). In this embodiment, since the same ink material is used for printing the symbol 832 and the pattern 810, the symbol 832 and the pattern 810 can be printed simultaneously. However, the ink material used for printing the symbol 832 and the ink material used for printing the pattern 810 may be different from each other, and in that case, the printing may be performed in two steps.

  FIG. 18 is an explanatory diagram showing a state in which a pattern 810, a symbol 832, and the like are formed on the control board 800 by the above-described steps. As shown in the drawing, on the control board 800, a symbol 832 indicating the name and mounting of an electronic component is formed at a predetermined position, and a pattern 810 is formed in the vicinity of the position where the index mark 910 is pressed. .

  When the pattern 810 or the like is printed by silk printing (S840), subsequently, a “solder leveling process” is performed on the portion where the solder resist layer 830 is not formed (S845), thereby the inner peripheral surface of the through hole 808 and the like. Solder coating is applied to the land portion of the opening of the through hole 808. In this solder leveling process, “flux treatment”, “solder immersion”, “hot air leveling”, etc. are performed in this order after “pre-treatment” such as degreasing / derusting, soft etching, etc. “Post-processing” is performed.

  After the solder leveling process is performed, other processes (for example, a drying process and an external finishing process) are performed (S850), and further, through various electronic component mounting processes such as the capacitor 600, the IC chip 700, and the IC socket 750 ( S860), the control board 800 is completed. In the completed control board 800, a seal seal 900 is applied from above the IC chip 700, and further, a split mark 910 is provided between the seal seal 900 and the control board 800, as shown in FIG. The chip 700 can be sealed.

  As described above, a lattice-like pattern 810 is printed on the control board 800 of the gaming machine 1 so that at least a part of the control board 800 overlaps the index mark 910, and the index mark 910 is removed by an erasable chemical. Ink material is used. Therefore, if the index 910 remaining on the control board 800 side is to be erased after the seal seal 900 is peeled off, a part of the pattern 810 on the control board 800 is also erased together with the index 910. For this reason, even if the IC chip 700 on the control board 800 is replaced with an illegal part and then a forged seal seal or mark is applied, a trace of the mark 910 being erased remains on the control board 800. Thus, such unauthorized modification can be easily detected, and thus unauthorized modification can be effectively prevented.

  In this embodiment, since the pattern 810 is printed simultaneously with the symbol 832, the pattern 810 can be easily formed.

C-1. First modification:
In the above-described embodiment, the pattern 810 is printed using an ink material that is removed by chemicals that can be erased to remove at least a part of the pattern 810 when the index 910 is erased. . However, the present invention is not limited to such an embodiment. As will be described below, a resin layer that is dissolved by chemicals capable of erasing the index 910 is formed on the surface of the control substrate 800, and the resin layer A pattern may be printed on top.

  FIG. 19 is an explanatory diagram showing a laminated structure of the control board 800 according to the first modification. As shown in the figure, a resin layer 840 that is dissolved by a chemical that can erase the index 910 is formed on the surface of the control substrate 800, and a pattern 842 is printed on the resin layer 840. Even in this case, if the index 910 is erased with a chemical, the surface of the resin layer 840 is dissolved, and as a result, at least a part of the pattern 842 is also erased, so that unauthorized modification can be easily detected.

  In order to manufacture the control board 800 according to the first modified example, in the manufacturing process described with reference to FIG. 16, the resin layer 840 is provided between the solder resist forming process (S835) and the silk printing process (S840). The formation process may be performed.

C-2. Second modification:
In the first modified example, the pattern 842 is printed on the surface of the resin layer 840 that is dissolved by a chemical that can erase the index 910. However, the present invention is not limited to this, and the surface of the resin layer 840 is uneven. By forming it into a shape, various uneven patterns such as a “satin texture pattern” and a “frosted glass pattern” may be formed.

  FIG. 20 is an explanatory diagram showing a laminated structure of the control board 800 according to the second modification. As shown in the figure, a resin layer 840 that is dissolved by a chemical that can erase the index mark 910 is formed on the surface of the control substrate 800, and an uneven pattern (uneven pattern) 844 is formed on the surface of the resin layer 840. Is formed. Even in such a configuration, if the index 910 is erased with a chemical, the surface of the resin layer 840 is dissolved, and as a result, at least a part of the pattern 844 disappears, so that unauthorized modification can be easily detected. Further, if the pattern 844 is configured to be uneven, it is more difficult to restore the uneven pattern 844, so that unauthorized modification can be more effectively prevented.

  In order to manufacture the control board 800 according to the second modified example, the concave / convex pattern 844 may be formed simultaneously with the formation of the resin layer 840, or after the formation of the resin layer 840, a sand blaster device, a marking device, or the like. The uneven pattern 844 may be added by processing with the above.

C-3. Third modification:
In the second modified example described above, as shown in FIG. 20, the uneven pattern 844 is formed on the resin layer 840 laminated on the solder resist layer 830, but the present invention is not limited to this. An uneven pattern may be formed on the solder resist layer.

  FIG. 21 is an explanatory diagram showing a laminated structure of the control board 800 according to the third modification. The solder resist layer 850 of this modification is formed of a solder resist ink that is dissolved by a chemical that can erase the index 910. As shown in the drawing, the surface of the solder resist layer 850 has an uneven pattern (uneven pattern) 852. Is formed. Even in such a configuration, if the index 910 is erased with a chemical, the surface of the solder resist layer 850 is dissolved, and as a result, at least a part of the concavo-convex pattern 852 disappears, so that unauthorized modification can be easily detected. .

  In order to manufacture the control substrate 800 according to the third modified example, when the solder resist layer 850 is formed, a concavo-convex pattern 852 may be added together, or after the solder resist layer 850 is formed. The pattern 852 may be formed by processing with a sand blaster or a marking device.

C-4. Fourth modification:
Moreover, in the said Example, as demonstrated using FIG. 17 etc., although the pattern 810 is printed on the surface of the soldering resist layer 830, it is not restricted to this, A pattern is formed under a soldering resist layer. May be printed.

  FIG. 22 is an explanatory diagram showing a laminated structure of the control board 800 according to the fourth modification. Similarly to the third modified example, the solder resist layer 860 of the present modified example is formed of a solder resist ink that is dissolved by an erasable chemical, and a pattern 862 under the solder resist layer 860 is also formed. The index 910 is printed using an ink material dissolved by an erasable chemical. Even in this case, when the index 910 is erased with a chemical, the solder resist layer 860 is dissolved, so that the pattern 862 can be erased.

  In order to manufacture the control board 800 according to the fourth embodiment, the pattern 862 may be printed before the solder resist forming step (S835) described above with reference to FIG.

  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 embodiment, the present invention has been described as being applied to a revolving game machine. However, the present invention is not limited to this, and for example, a ball game machine such as a pachinko game machine or an arrange ball game machine. The present invention can be applied.

  Moreover, in the said Example, although demonstrated as a thing in which a pattern disappears with the chemical | medical agent which can delete a mark, it is not restricted to this. For example, the pattern may be formed so as to be easily erased by friction, and in this case, even when the marking is erased, the pattern disappears and a trace of illegal modification can be left.

  In the above-described embodiment, the pattern is formed only in the vicinity of the position where the marking is imprinted (see FIGS. 15 and 18). However, the present invention is not limited to this, and the pattern is formed on the entire control board. It may be formed.

  Further, in the above embodiment, the present invention is applied to the configuration in which the IC chip is sealed with a sealing seal. However, the present invention is not limited to this, and other electronic components may be sealed with a sealing seal. The present invention can be applied.

  In the above embodiment, “silk printing” is adopted as a printing method when a pattern is formed by printing. However, the printing method is not limited to this, and various printing methods can be adopted. For example, an inkjet method may be employed.

  Control boards such as the main control board 101 and the sub control board 105 are housed in a board case. However, in order to more effectively prevent unauthorized modification, a caulking structure is adopted for the board case, It is desirable that the substrate case containing the control board be sealed, for example, by sticking a seal seal. Thereby, when the substrate case is opened for the purpose of illegal modification, a trace of the opening can be left.

  Further, when a rewritable ROM such as an EPROM or a flash ROM is mounted on the control board, for example, the electrical terminals in a state where the ROM is not mounted on the board by a connector or the like and mounted on the board. It is desirable to prevent rewriting. Thereby, it is possible to prevent the ROM from being rewritten illegally in a state where it is mounted on the substrate.
