<Main control board>
3 and 4 are external views of the surface of the main control board 210. FIG. In this embodiment, the front surface refers to one surface on which electronic components are mounted (also referred to as a mounting surface), and the back surface refers to one surface on which electronic components are not mounted (solder is exposed). It is also called a solder side. Specifically, FIG. 3 is an external view of the surface of the main control board 210 in a state where no electronic component is mounted, and is an external view showing the ground pattern 211 formed on the board. FIG. 4 is an external view of the surface of the main control board 210 with electronic components mounted thereon, and is an external view in which the ground pattern 211 is omitted. As shown in FIGS. 3 and 4, a company name 212 is described at the upper right end portion of the front surface of the main control board 210 (not shown, but the company name 212 is also described on the back surface). )

  As described above, the main control board 210 of the present embodiment has identification information for fraudulent board determination on the surface. Here, the main control board 210 provided with identification information for determining illegal boards means the main control board 210 in which a predetermined forgery discrimination rule is formed on the board or an electronic component mounted on the board. That is, the mounting rules on the main control board are different between the main control board 210 subjected to the forgery determination rule and the main control board not subjected to the forgery determination rule. And the forgery determination rule is a rule that can be determined as an error that occurs when designing a circuit board, and is not visually conspicuous, so if someone who recognizes the forgery determination rule sees it, While it is easy to discriminate between a board (main control board 210) and an unauthorized board (for example, an unauthorized board imitating the main control board 210), even if a person who does not recognize the forgery discrimination rule sees it, It is difficult to find the difference between the two control boards.

  Since various patterns exist in the forgery determination rule applied to the main control board 210 of the present embodiment, each pattern will be specifically described below. In the first to fifth embodiments, forgery discrimination rules are provided in the ground pattern 211 of the main control board 210, and the sixth to ninth embodiments are mounted on the main control board 210. It is the Example which provided the forgery discrimination rule in the silk character for identifying the electronic component or the said electronic component. In the following, the main control board of each embodiment is represented as a main control board 210A, B,..., And the main control board 210A, B,. Is written.

(First embodiment)
FIG. 5A is a main part diagram of the main control board 210A provided with the forgery determination rule of the first embodiment. FIG. 5A shows the shape of the ground pattern 211 in the vicinity of the company name 212. Specifically, the arrangement positions of the three ground patterns G1, G2, and G3 are shown.

  As shown in FIG. 5A, the ground pattern G1 is arranged slightly shifted downward in comparison with other adjacent ground patterns G2 and G3. That is, the ground patterns G2 and G3 are arranged on the reference line L1 whose upper edge is normally arranged, while the ground pattern G1 is forged with its upper edge slightly shifted from the reference line L1 and located below. It is arranged on the circuit board identification line L2. Here, the difference in the vertical direction between the reference straight line L1 and the counterfeit circuit board identification straight line L2 is visible to the naked eye, but is preferably a distance that cannot be determined that the deviation is apparent at first glance. About 2 mm is preferable. This is because if the distance is set so that it can be determined that the deviation is obvious, the person who makes the illegal substrate will notice the deviation, and the same illegal substrate may be manufactured. The reference straight line L1 and the counterfeit circuit board identification line L2 are virtually drawn straight lines and are not actually written on the board. In the first embodiment, the reference straight line L1 and the counterfeit circuit board identification straight line L2 are provided near the outer edge on the main control board 210A. This makes it easy to discriminate the deviation (inside the main control board 210A). If it is provided, it may be difficult to visually recognize where the forgery discrimination rule is located due to the arrangement of other components.

  As described above, in the first embodiment, the forgery determination rule is formed on the main control board 210A by making the arrangement of one ground pattern G1 different from the arrangement of the other ground patterns G2 and G3. That is, in the first embodiment, the forgery determination rule is the arrangement rule for the ground pattern 211. In the main control board that has not been subjected to the counterfeit discrimination rule, the ground patterns G1, G2, and G3 are arranged with their upper edges aligned with the reference straight line, and there is no vertical shift between the ground patterns. It has not occurred.

  Therefore, according to the first embodiment, a person who confirms forgery determination visually recognizes the displacement in the arrangement of the ground pattern 211 of the main control board 210A, so that the main control board 210A is a regular board or an illegal board. Can be determined. On the other hand, a third party who does not know the forgery discrimination rule (for example, a person who makes an illegal board and tries to replace the regular board with an illegal board) does not notice a deviation in the arrangement of the ground pattern 211 on the main control board 210A. The main control board 210A subjected to the forgery discrimination rule cannot be imitated. In addition, although the possibility that the counterfeit circuit board created by a third party has the same configuration as the main control board 210A in which the slight deviation of the ground pattern G1 is accidentally formed can be considered, in this embodiment, It is considered that the possibility that a third party who performs fraud is not aware of the slight deviation of the ground pattern G1 is much higher than the possibility.

  In the first embodiment, the forgery determination rule is formed in the ground pattern 211 in the vicinity of the company name 212 (the largest identification character on the main control board 210A). It is only necessary to visually recognize the vicinity of the prominent company name 212 on the main control board 210A, and it is easy to find a counterfeit discrimination rule.

(Second embodiment)

  As shown in FIG. 5B, the ground patterns G1, G2, and G3 are arranged so that their upper edges coincide with each other, but a stepped portion 213 that is recessed inward at a part of the upper edge of the ground pattern G1. Is formed. Here, the dent of the stepped portion 213 (the recessed bottom of the recessed stepped portion 213) is visible with the naked eye as in the first embodiment, but cannot be discriminated that the deviation is apparent at first glance. The distance is desirable, and about 0.5 mm to 2 mm is preferable. That is, the ground patterns G2 and G3 are arranged on the reference straight line L1 (not shown in FIG. 5B, see FIG. 5A) whose upper edges are normally arranged, while the ground patterns G1 The bottom side of the stepped portion 213 is arranged on the counterfeit circuit board identification line L2 (not shown in FIG. 5B, see FIG. 5A) positioned slightly below the reference line L1 and below. .

  As described above, in the second embodiment, by providing a step in the outer shape of one ground pattern G1, the arrangement of one ground pattern G1 is different from the arrangement of the other ground patterns G2 and G3. A counterfeit discrimination rule is formed on 210B. That is, also in the second embodiment, the forgery discrimination rule is the ground pattern arrangement rule. Note that, in the main control board that has not been subjected to the counterfeit discrimination rule, the stepped portion 213 is not formed in a part of the upper edge of the ground pattern G1, so that the upper edges of the ground patterns G1, G2, and G3 have the upper edge. Arranged so as to coincide with the reference straight line.

  Therefore, according to the second embodiment, the person who confirms the forgery determination visually recognizes the displacement (dent) in the arrangement of the ground pattern 211 of the main control board 210B, so that the main control board 210B is a regular board. It is possible to determine whether the board is an illegal board. On the other hand, a third party who does not know the forgery discrimination rule (for example, a person who makes an illegal board and tries to replace the regular board with an illegal board) does not notice a deviation in the arrangement of the ground pattern 211 on the main control board 210B. The main control board 210B subjected to the forgery discrimination rule cannot be imitated.

  In the second embodiment, the forgery discrimination rule is formed in the ground pattern 211 in the vicinity of the company name 212, so that the person who confirms the forgery discrimination is only in the vicinity of the company name 212 that stands out on the main control board 210B. It is easy to find counterfeit discrimination rules.

  Furthermore, in the second embodiment, the forgery determination rule is formed using the ground pattern G1 having the stepped portion 213 provided in advance, so that chances are surely eliminated. That is, in the first embodiment, although the probability is low, the forgery discrimination rule shown in FIG. 5 (a) may be formed accidentally, but in the second embodiment, such a chance is surely excluded. Is done.

(Third embodiment)
FIG. 6A is a main part diagram of the main control board 210C provided with the forgery determination rule of the third embodiment. FIG. 6A shows the shape of the ground pattern 211 in the vicinity of the company name 212. Specifically, the arrangement positions of the two ground patterns G1 and G2 are shown.

  As shown in FIG. 6A, the ground pattern G1 is arranged slightly shifted in the downward direction as compared with the other adjacent ground pattern G2. That is, the ground pattern G2 is arranged on the reference line L1 whose upper edge is normally arranged, while the ground pattern G1 is a counterfeit circuit board whose upper edge is slightly shifted from the reference line L1 and located below. It arrange | positions on the identification straight line L2. Here, since the dimension of the difference in the vertical direction between the reference straight line L1 and the counterfeit circuit board identification straight line L2 is the same as that in the first embodiment, the description thereof is omitted.

  As described above, in the third embodiment, the forgery determination rule is formed on the main control board 210C by making the arrangement of one ground pattern G1 different from the arrangement of another ground pattern G2. That is, in the state where the two ground patterns G1 and G2 are adjacent to each other, the forgery determination rule may be formed so that one ground pattern G1 is different from another one ground pattern G2. In the main control board that does not form the counterfeit discrimination rule, the ground patterns G1 and G2 are arranged with their upper edges aligned with the reference straight line, and the vertical deviation occurs between the two ground patterns G1 and G2. Not.

  Therefore, according to the third embodiment, as in the first embodiment, the person who confirms the forgery determination visually recognizes the deviation in the arrangement of the ground pattern 211 in the vicinity of the company name 212 of the main control board 210C. It is possible to easily determine whether the main control board 210C is a regular board or an unauthorized board. Further, as in the first embodiment, a third party who does not know the forgery determination rule does not notice the displacement in the arrangement of the ground pattern 211 of the main control board 210C. It cannot be created.

(Fourth embodiment)
FIG. 6B is a main part diagram of the main control board 210D provided with the forgery determination rule of the fourth embodiment.

FIG. 6C shows the shape of the ground pattern 211 in the vicinity of the heat sink 215. Specifically, the arrangement positions of the two ground patterns G1 and G2 are shown.

  The ground pattern G1 shown in FIG. 6C is the same as the ground pattern G1 shown in FIG. That is, the ground pattern G1 is arranged slightly shifted downward as compared with the other adjacent ground pattern G2, and the shift is the same as that of the third embodiment.

  As described above, in the fifth embodiment, the arrangement of one ground pattern G1 in the vicinity of the heat sink 215, which is an electronic component that stands out on the board, is different from the arrangement of the other adjacent ground pattern G2, and the main control board 210E. A counterfeit discrimination rule is formed above.

  That is, the fifth example is different from the third example only in that the forgery determination rule formed in the vicinity of the company name 212 in the third example is formed in the vicinity of the heat sink 215 which is a prominent electronic component. This is the same as the third embodiment. Even in this case, the person who confirms the counterfeit discrimination only needs to visually recognize the vicinity of the heat sink 215 conspicuously on the main control board 210, so that the counterfeit discrimination rule can be easily found, and the main control board 210E is the regular board. It is possible to easily determine whether the board is an illegal board.

  In this embodiment, the counterfeit discrimination rule is formed on the ground pattern G1 near the heat sink 215. However, if the counterfeit discrimination rule is a visually noticeable electronic component, the counterfeit discrimination rule is applied to the ground pattern near the electronic component other than the heat sink 215. It may be formed. Here, the visually conspicuous electronic component is an electronic component whose appearance such as size and color is conspicuous compared with other electronic components and can be recognized at a glance. The heat sink 215 is the largest electronic component on the main control board 210E.

(Sixth embodiment)
FIG. 7A is a main part view of the main control board 210F provided with the forgery discrimination rule of the sixth embodiment. FIG. 7A shows an arrangement position of an electronic component 216 (for example, a resistor) mounted on the substrate of the main control board 210F and a silk character 217 for explaining the electronic component 216. 7A, a plurality of electronic components 216 (for example, resistors) having the same function are arranged in the vertical direction, and silk letters 217 corresponding to the plurality of electronic components 216 are respectively electronic components 216. The case where it is displayed on the right side of is shown.

  As shown in FIG. 7A, the plurality of electronic components 216 are arranged at equal intervals in the vertical direction, but the silk letters 217 associated with the electronic components 216 are partially non-vertical in the vertical direction. They are arranged at equal intervals. Specifically, the vertical interval d2 between the silk character “R17” and the silk character “R18” is arranged to be wider than the vertical interval d1 between other silk characters (thus, silk The vertical space d3 between the character “R16” and the silk character “R17” is arranged to be narrower than the vertical space d1 between other silk characters).

  Thus, in the sixth embodiment, a plurality of electronic components 216 having the same function are arranged, and the vertical direction of a specific silk character 217 in the vicinity of the electronic component group that stands out on the substrate. The forgery discrimination rule is formed on the main control board 210F by differentiating the arrangement of the above-mentioned from the arrangement of the other silk characters 217 in the vertical direction. That is, in the sixth embodiment, the forgery determination rule is the arrangement rule for the silk characters 217. In the main control board that does not form the forgery determination rule, the silk character strings are arranged at equal intervals d1 in the vertical direction.

  Therefore, according to the sixth embodiment, the person who confirms the forgery determination visually recognizes the displacement in the vertical arrangement of the silk letters 217 written on the right side of the electronic component 216 of the main control board 210F. It is possible to easily determine whether the main control board 210F is a regular board or an unauthorized board. On the other hand, since a third party who does not know the forgery discrimination rule does not notice the vertical displacement of the silk characters 217 of the main control board 210F, the third party imitates the main control board 210F with the forgery discrimination rule. It is not possible.

  Further, in the sixth embodiment, the counterfeit discrimination rule is formed at the portion where the plurality of electronic components 216 having the same function are arranged, so that the person who confirms the counterfeit discrimination is the board of the main control board 210F. It is only necessary to visually recognize the vicinity of the electronic component 216 that stands out above, and it is easy to find a counterfeit discrimination rule.

  In this embodiment, the vertical interval between the silk character “R16” and the silk character “R17” is made narrower than usual. However, the silk character “R16” and the silk character “R17” are made narrower. You may arrange | position so that a part may overlap.

  In the present embodiment, the case where the silk character string 217 corresponding to the electronic component is arranged on the right side of the electronic component has been described. However, the arrangement position of the silk character string 217 is not limited thereto, and is close to the electronic component 216. Any position may be used as long as it is arranged in association with the electronic component 216.

  Furthermore, when the arrangement rule of the silk character string 217 is a forgery determination rule, various modifications can be considered. FIG. 7B shows a modification of the sixth embodiment.

  The silk character 217a shown in FIG. 7B forms a forgery discrimination rule in one silk character string “R20”. That is, in the silk character “R20”, since the arrangement position of “0” is shifted to the right side than usual, the character interval d2 between “2” and “0” becomes wider than the normal character interval d1. Yes. In the silk character “R20”, a punctuation mark 218a “.” Is added after “0”.

  The silk character 217b shown in FIG. 7B also forms a forgery discrimination rule in one silk character string “R19”. That is, in the silk character “R19”, since the arrangement position of “R” is shifted to the right side than usual, the character interval d3 between “R” and “1” is narrower than the normal character interval d1. Yes. Further, in the silk character “R19”, only the font “1” is printed differently (“1” of the silk character 217b shown in FIG. 7B and “1” of the silk character shown in FIG. 7A). ).

  As shown in FIG. 7B, “1” of the silk character “R19” is changed to another character after printing the normal font “1” (after printing the silk character “R19”). In the process, the additional portion 218b may be printed over the “1” portion so that only the font “1” is different. That is, after the silk characters are printed with the same common font at first, the fonts of the specific silk characters may be different as a result of printing with additional marks superimposed only on the specific silk characters. Of course, the silk character 217b may be printed in a single process.

  As described above, in the modification of the sixth embodiment, a plurality of electronic components 216 having the same function are arranged, and the specific silk characters 217a and 217b in the vicinity of the portion that is conspicuous on the substrate are arranged. Forgery discrimination rules are formed on the main control board 210F by making the arrangement in the silk letters different from the arrangement in the silk letters of the other silk letters 217. That is, also in the modified example of the sixth embodiment, the forgery determination rule is the arrangement rule of the silk characters 217a and 217b.

  Therefore, according to the modification of the sixth embodiment, the person who confirms the forgery determination is arranged on the arrangement of the silk characters 217a and 217b on the right side of the electronic component 216 on the main control board 210F in the silk character string. By visually recognizing the deviation, it is possible to easily determine whether the main control board 210F is a regular board or an unauthorized board.

FIG. 8A shows an arrangement position of an electronic component 216 (for example, a resistor) mounted on the board of the main control board 210. FIG. 8A shows a case where a plurality of electronic components 216 (for example, resistors) having the same function are arranged in two rows in the vertical direction.

  In the seventh embodiment, as shown in FIG. 8A, some of the electronic components 216 include a counterfeit determination mark b in addition to the resistance value (color code) a. Is added.

  In this way, in the seventh embodiment, a plurality of electronic components 216 having the same function are arranged, and in a portion that stands out on the substrate, a counterfeit discrimination mark b is provided on some of the electronic components 216. Is added to make it different from the other electronic components 216 in appearance, and forgery discrimination rules are formed on the main control board 210G. That is, in the seventh embodiment, the forgery determination rule is a mark written on the electronic component 216. It should be noted that the counterfeit discrimination mark b is not described in any of the plurality of electronic components 216 in the main control board that does not form the counterfeit discrimination rule.

  Therefore, according to the eighth embodiment, the person who confirms the forgery determination visually recognizes the presence or absence of the forgery determination mark b written on the electronic component 216 of the main control board 210G, so that the main control board 210 is properly registered. It is possible to easily determine whether it is a substrate or an unauthorized substrate. On the other hand, since a third party who does not know the forgery determination rule does not notice the presence of the forgery determination mark b written on the electronic component 216 of the main control board 210G, it imitates the main control board 210G with the forgery determination rule. Cannot be created.

(Eighth embodiment)
FIG. 8B is a main part diagram of the main control board 210H provided with the forgery discrimination rule of the eighth embodiment. FIG. 8B shows an arrangement position of an electronic component 219 (for example, an IC such as a ROM) mounted on the board of the main control board 210H.

  As shown in FIG. 8B, when a plurality of electronic components 219 are mixed with parts from a plurality of manufacturers, for example, a notch 221 is formed on the left side for the electronic component 219a manufactured by Company A. In addition, regarding the electronic component 219b manufactured by B company, the cutout portion 221 is formed on the right side.

  As described above, in the eighth embodiment, the arrangement of one electronic component 219a is different from the arrangement of another electronic component 219b, and the forgery determination rule is set in the arrangement direction of the electronic component 219 mounted on the main control board 210H.

In the main control board that does not form the forgery discrimination rule, the electronic component 219a manufactured by company A and the electronic component 219b manufactured by company B are both arranged with the notch 221 facing in the same direction.

  Therefore, according to the eighth embodiment, a person who confirms forgery determination visually recognizes the orientation of the electronic components 219 on the main control board 210G, so that the main control board 210G is a regular board or an unauthorized board. Can be easily determined.

(Ninth embodiment)
FIG. 8C is a main part view of the main control board 210I provided with the forgery determination rule of the ninth embodiment. FIG. 8C shows an installation direction of the electronic component 222 (for example, a capacitor) mounted on the board of the main control board 210I.

  As shown in FIG. 8C, the electronic component 222 is disposed at a slight inclination with respect to the substrate. That is, in the ninth embodiment, the forgery determination rule is formed in the installation direction of the electronic component 222 mounted on the main control board 210I. In the main control board that does not form the counterfeit discrimination rule, the electronic component 222 is erected vertically to the board.

Can be easily determined.

  Although FIG. 8C illustrates an example in which one electronic component 222 is disposed slightly obliquely from the vertical, the number of electronic components 222 disposed obliquely is limited to one. It may be plural. Also, a predetermined rule may be provided for the direction of tilting. For example, the electronic component 222 may be inclined toward the lower edge of the substrate. When the plurality of electronic components 222 are inclined in the vertical direction, the upper edge and the lower edge of the substrate are alternately inclined in a fixed direction. Also good.

<Board storage case>
Next, with reference to FIG. 9, a method for attaching the main control board 210 provided with the forgery determination rule of each embodiment described above to the inside of the housing of the slot machine 100 will be described.

  As shown in FIG. 9A, the main control board 210 is housed in a board housing case 240 and installed inside the housing. That is, the board storage case 240 includes a front cover 250, a back cover 260, and a main control board 210 as shown in FIG. Since the front cover 250 and the back cover 260 of the substrate storage case 240 are molded using a translucent resin in the present embodiment, the main control substrate 210 stored inside from the outside of the substrate storage case 240 is visually recognized. It is possible.

  As shown in FIG. 9 (b), the substrate storage case 240 forms a single box for storing the main control substrate 210 inside by combining the front cover 10 and the back cover 20, so that in this combined state As shown in FIG. 9A, the substrate storage case 240 is installed on the back surface above the reel unit. At this time, the substrate storage case 240 is installed in a state in which the front cover 250 faces the front side, that is, in a state in which the front cover 250 is visible when the front door 102 is opened.

  In the present embodiment, as described above, the surface of the main control board 210 has a counterfeit discrimination rule, so that the counterfeit discrimination rule is visible from the outside when the front door 102 is opened. . That is, in the present embodiment, the main control board 210 has a counterfeit discrimination rule on the surface and the front cover 250 is made of a translucent resin. Therefore, a person who confirms the counterfeit discrimination can easily perform the main control board 210 from the outside. The above counterfeit discrimination rule can be visually recognized.

  In this embodiment, as shown in FIG. 9B, at least a position A ′ where the forgery determination rule of the front cover 250 can be visually recognized (a position that covers the forgery determination rule of the main control board 210, The front cover position positioned immediately above or near the forgery discrimination rule provided on the control board 210 is a smooth shape. The reason why the position A ′ of the front cover 250 is smooth is that it is difficult to visually recognize the forgery determination rule of the main control board 210 through the front cover 250 when the unevenness is formed.

  Note that a mark may be added near the position A ′ of the front cover 250 in order to make the visual recognition position clearer. Here, for example, when the silk character “R17” is printed on the main control board 210, “R17” is added as a molded character to the front cover 250 positioned immediately above the silk character “R17”. As described above, the information having the same meaning may be added to both the main control board 210 and the front cover 250. In this case, the person who confirms the forgery determination looks for the mark position of the front cover 250, and when there is a mark corresponding to the front cover 250 and there is no mark corresponding to the main control board 210. In addition, it can be determined that the main control board 210 is an unauthorized board.

<Basic control of games>
FIG. 12 is a flowchart of main processing of the main control unit showing basic control of the game in the slot machine 100 of the present embodiment. Basic control of the game is performed mainly by the Main CPU 310 of the main control unit 300, and the processing of steps S102 to S109 in FIG.

  In step S101, when power is turned on, first, various initialization processes are performed.

  In step S102, processing related to medal insertion is performed. Here, it is checked whether or not medals have been inserted, and the winning line display lamp 120 is turned on according to the number of medals inserted. It is not necessary to insert a medal when winning the re-game in the previous game.

  In step S103, processing related to a game start operation is performed. Here, it is checked whether or not the start lever 135 has been operated. If it is determined that the start operation has been performed, the number of inserted medals is determined. In addition, a start lever reception command is transmitted to the sub-control unit 400. The sub-control unit 400 grasps the start of the game by receiving this start lever reception command.

  In step S104, a valid winning line is determined.

  In step S105, the random number generated by the random number generator 311 is acquired.

  In step S106, an internal lottery of a winning combination is performed using the random number acquired in step S105 and the lottery data in the winning combination lottery table stored in the ROM 312. As a result of the internal lottery, when any winning combination is won internally, the winning combination flag is internally turned ON. Also, an internal winning result command is transmitted to the sub-control unit 400. For example, internal winning result commands such as re-game winning, BB (big bonus) winning, small role 1 winning, small role 2 winning, and small role 3 winning are transmitted. The sub-control unit 400 grasps the result of the internal lottery by receiving this internal winning result command. In step S106, reel stop control data is selected based on the internal lottery result.

  In step S107, rotation of all reels 110 to 112 is started by reel rotation start processing.

  In step S108, the stop buttons 137 to 139 can be accepted, and the rotation of the reels 110 to 112 corresponding to the pressed stop buttons 137 to 139 is stopped by the reel control process. At this time, the reels 110 to 112 are stopped based on the reel stop control data selected in step S106. In step S108, a stop position symbol command is transmitted to the sub-control unit 400. By receiving this stop position symbol command, the sub-control unit 400 grasps at which symbol position each reel 110 to 112 is stopped.

  In step S109, the winning determination of the symbols stopped when the stop buttons 137 to 139 are pressed is performed. Here, it is determined that the winning combination has been won when the winning symbol combination corresponding to the winning combination won or the flag carryover winning combination is displayed (displayed) on the active line. For example, if “Replay-Replay-Replay” is arranged on the active line, it is determined that the game is won again. In step S109, a determination result command is transmitted to the sub-control unit 400. For example, in this embodiment, determination result commands such as a BB prize, a re-game prize, and a small role 1 prize are transmitted. The sub-control unit 400 grasps the winning result by receiving the determination result command.

  In step S110, a medal payout process is performed. In this medal payout process, if any winning combination with payout (dividend) is won, the number of medals corresponding to the winning combination is paid out.

  In step S111, game state control processing is performed. In the game state control process, control for shifting the game state is performed. For example, in the case of BB winning, preparation is made so that the BB game can be started from the next time, and in those final games, the normal game can be started from the next time. prepare. In step S111, a state command indicating the current gaming state is transmitted to the sub-control unit 400. The sub-control unit 400 grasps the current gaming state by receiving this state command.

  Thus, one game is completed, and thereafter, the game proceeds by repeating steps S102 to S111.

  As described above, according to the main control board 210 of the slot machine 100 of the present embodiment, it is a rule that can be determined as an error that occurs when a circuit board is designed on the main control board 210, and visually. Since the counterfeit discrimination rules that are not conspicuous are applied, it is difficult to notice that the counterfeit countermeasure is taken even if the counterfeit countermeasure is taken, and it is possible to easily confirm whether the board is a regular board or an illegal board.

<Other embodiments>
As mentioned above, although embodiment of this invention has been described, various deformation | transformation and change can be performed with respect to embodiment of this invention in the range which does not deviate from the summary of this invention.

  For example, in the main control board 210 of the above embodiment, the forgery determination rule is formed on the front surface, but may be formed on the back surface. FIG. 13A is a diagram showing a main part of the main control board 210J in which forgery discrimination rules are formed on the back surface. FIG. 13A shows the state of the front and back surfaces when an electronic component 219 (for example, an IC such as a ROM) disposed near the company name 212 is soldered to the substrate.

  As shown in FIG. 13A, the plurality of pins 223 protruding from the electronic component 219 are fixed to the substrate by solder 224 in a state where the pins 223 pass through holes formed in the substrate and protrude from the back surface. . At this time, among the plurality of pins 223, a specific pin 223a is clinched (bended state) and soldered.

  Thus, in this modification, the clinch of the specific pin 223a of one electronic component 219 is used as a forgery determination rule. Note that specific pins are not clinched in one electronic component 219 of the main control board that does not form counterfeit discrimination rules. In order to facilitate the discovery of this specific pin 223a, in this modification, a mark mark 225 is attached to the pin position on the corresponding surface.

  Therefore, according to this modification, the person who confirms the forgery determination can visually recognize the presence or absence of the clinch of the specific pin 223 of the electronic component 219 disposed near the company name 212 of the main control board 210J. It is possible to easily determine whether the substrate 210J is a regular substrate or an unauthorized substrate. On the other hand, since a third party who does not know the forgery determination rule does not notice the clinch of the specific pin 223a of the main control board 210J, the third party cannot imitate the main control board 210J subjected to the forgery determination rule.

  In FIG. 13A, the clinch of the specific pin 223a of the electronic component 219 is set as a forgery determination rule. However, as shown in FIG. 13B, the amount of solder when the pin 223 is soldered is determined as a forgery. It is good also as a rule, and as shown in FIG.13 (c), it is good also considering the leg length of the pin 223 as a forgery discrimination rule.

  For example, as shown in FIG. 13B, the amount of solder 224a soldering a specific pin 223a exposed on the back surface is more conspicuous than the amount of solder 224 soldering another pin 223. It is increasing. In this way, in the modification shown in FIG. 13B, the forgery determination rule is the amount of solder expressed on the back surface. It should be noted that the amount of solder is substantially uniform on the back surface of the main control board where no forgery discrimination rule is applied.

  Moreover, as shown in FIG.13 (c), the length of the leg | foot of the specific pin 223a exposed on the back surface is remarkably longer than the length of the leg | foot of the other pin 223. FIG. As described above, in the modification shown in FIG. 13C, the forgery determination rule is the length of the foot of the pin 223 protruding from the back surface. Note that the lengths of the legs of the pins 223 are substantially uniform on the back surface of the main control board on which no forgery determination rule is applied.

  In this way, the forgery determination rule may be formed on the back surface in addition to being formed on the front surface of the main control board 210.

  In the above embodiment, an example in which a counterfeit discrimination rule is provided for the main control board 210 has been described. However, a control board that provides a counterfeit discrimination rule is not limited to the main control board 210. For example, forgery determination rules may be provided for the sub-control board 220, the display control board 230, and the relay board.

  In the above embodiment, the present invention is applied to a slot machine using medals. However, the present invention is not limited to this. For example, a slot using a game ball (for example, a pachinko ball) as a game medium. It can also be applied to machines and pachinko machines.

  For example, the control board provided with the counterfeit discrimination rule used in the embodiment and the modification example described above is configured to be able to enter a launching device that launches a ball into a predetermined game area and a ball launched from the launching device. A winning opening, a detecting means for detecting a ball that has entered the winning opening, a payout means for paying out a ball when the detecting means detects a ball, and a variable display device that variably displays a predetermined symbol (identification information). It may be used for a pachinko gaming machine in which a variable display device displays a stop after a change of a symbol and notifies a transition of a gaming state when a game ball enters the winning opening and wins. .
