Description

  The present invention relates to a protection structure for a gaming machine storage medium including a control board having a storage medium for a gaming machine, and a board case for housing the control board, and a gaming machine including the protection structure.

  A gaming machine such as a pachinko machine or a slot machine is provided with a plurality of control boards on which various electronic components are mounted, and the control boards are accommodated in a board case. A storage device ROM in which game control information such as game lottery is stored is mounted on such a control board. Then, the control board is housed inside the board case, and the board case is closed so that the storage device ROM of the control board cannot be accessed from the outside in a state of being arranged in the gaming machine.

  The board case is generally composed of a base body that covers the back surface of the control board and a cover body that covers the mounting surface of the control board. By assembling the base body and the cover body, The stored control board is protected. However, even if the substrate case is closed in this way, a metal device such as a wire is inserted through a gap between the cover body and the base body, or a hole or the like is illegally formed in a side portion of the substrate case. A case has been reported in which an illegal act of intruding and illegally accessing the storage device ROM mounted on the control board has been reported.

  As a configuration for preventing such an illegal act, for example, Patent Document 1 discloses a cover body that constitutes a substrate case provided with a frame portion that surrounds a storage device ROM mounted on a control board. In this conventional configuration, the cover body and the case body are assembled, and the frame portion of the cover body surrounds the storage device ROM of the control board. The frame portion can prevent unauthorized access to the storage device ROM.

Japanese Patent Laid-Open No. 10-41607

  In the conventional configuration of Patent Document 1 described above, in order to effectively prevent unauthorized access to the storage device ROM by the frame portion provided on the cover body, the mounting surface of the control board on which the storage device is mounted and the mounting surface It is required to make the gap with the lower end of the frame portion as small as possible. This is because, as the gap becomes larger, the above-mentioned elongated metal instrument can easily enter from the gap, and even when the gap is somewhat small, the tip of the metal instrument can be inserted into the gap to be forced into the gap. Because there is. However, if the frame part of the cover body is designed so that the gap between its lower end and the mounting surface of the control board is as small as possible, mistakes during the assembly work of the cover body and the base body and molding in manufacturing Due to an error or the like, the lower end of the frame body may interfere with the circuit on the mounting surface of the control board, which may damage the circuit. For this reason, in the conventional configuration of Patent Document 1, it is necessary to provide a slight gap between the lower end of the frame portion of the cover body and the mounting surface of the control board. Therefore, in the case of this conventional configuration, there is a limit to the effect of preventing fraud using the above-described elongated metal device.

  The present invention proposes a protection structure for a storage medium for gaming machines capable of improving the anti-fraud effect for preventing unauthorized access to a storage medium provided on a control board, and a gaming machine equipped with the protection structure. .

The present invention provides a gaming machine storage medium protective structure comprising a control board having a storage medium for a gaming machine and a board case for housing the control board, wherein the control board includes the first board and the storage board. A transparent case base that includes a medium mounted thereon and a second substrate smaller than the first substrate disposed on the mounting surface of the first substrate, and the substrate case covers a back surface of the first substrate. And a transparent case cover body that is assembled to the case base body so as to cover the mounting surface of the first substrate, and an interior that houses the first substrate by the assembled case cover body and the case base body An air space is formed, and the case cover body is formed so as to be recessed from the outside of the case and bulge toward the internal air space, and includes a storage recess for disposing the second substrate from the outside of the case. Furthermore, the case Is desorbed non joined to Sukaba body, comprising a transparent shielding member for shielding the housing recess, the housing recess of the case cover body, extending made the sidewall portion from the outer surface to the inner airspace side of the case cover body And a floor wall part formed from the lower end edge of the side wall part, and at least a part of the side wall part is constituted by a curved side wall part that curves convexly toward the internal airspace side. This is a protection structure for a storage medium for a gaming machine.

  Here, as the “storage medium for the gaming machine”, a storage device ROM storing game control information such as a lottery of game, a storage device RAM storing information indicating the progress of the game temporarily, etc. In particular, a storage device ROM in which the game control information is stored is preferably used. The second substrate is mounted with at least a storage medium for gaming machines, and a CPU may be mounted in addition to the storage medium. In addition, “joining the shielding member to the case cover body so as not to be detachable” means that the shielding member and the case cover body are bonded with a predetermined adhesive, and one of the shielding member and the case cover body has an elastic claw portion. And the other is preferably provided with a stepped portion that engages with the claw portion. Note that a UV curable adhesive is suitable for the adhesive.

In such a configuration, the second substrate on which the storage medium is mounted is divided from the first substrate on which other electronic components are mounted, and the second substrate is separated from the internal air space that houses the first substrate. An air space to be stored (hereinafter referred to as a storage air space) is formed by a storage recess and a shielding member, and the entire or most of the storage air space is formed inside the internal air space. And since the accommodation airspace which accommodates a 2nd board | substrate is divided with an internal airspace only by the accommodation recessed part formed in the case cover body, the control board in the conventional structure of the above-mentioned patent document 1 is included in the structure of this invention. There is no equivalent to the gap between the frame and the frame. For this reason, it is assumed that an elongated metal device enters the internal air space through the gap between the case cover body and the case base body, or the metal device enters the internal air space through a hole that is illegally opened on the side of the board case. Even when it is done, the metal device can be prevented from entering the storage airspace. Therefore, according to the configuration of the present invention, the effect of preventing unauthorized access to the storage medium of the second substrate disposed in the storage airspace is dramatically improved as compared with the conventional configuration of Patent Document 1.
In such a configuration, the curved side wall portion can be relatively easily visually recognized from the outside of the shielding member. Thereby, even if a hole is illegally opened in the curved side wall portion of the storage recess by the metal device that has entered the internal air space, the trace can be easily found. Therefore, such illegal intrusion can be prevented, and the above-described operational effect of the present invention for preventing unauthorized access to the storage medium of the second substrate is further improved.

  Note that the storage air space storing the second substrate is protected only by the shielding member on the second substrate. However, if the shield member is illegally infiltrated by opening a hole in the shield member or if it is illegally entered from the boundary between the shield member and the case cover body, the trace of the intrusion remains relatively clear, and the trace is easily Can be found in Therefore, the configuration of the present invention is highly effective in preventing unauthorized access to the storage medium of the second substrate due to such intrusion.

  Moreover, the thing of the structure of this invention can be manufactured by attaching a shielding member, accommodating a 2nd board | substrate in an accommodation recessed part, after attaching a case cover body and a case base body. That is, the process until the case base body and the case cover body are assembled so as to store the first substrate and the process of storing the second substrate in the storage recess of the case cover body and bonding the shielding member thereafter are separated. Can be implemented separately. Thereby, for example, even if a lot of time is spent developing game control information recorded on the recording medium, the process until the case base body and the case cover body are assembled in parallel with the development. After implementing and developing the game control information, a step of disposing a second substrate on which the recording medium is mounted can be performed. Therefore, the configuration of the present invention can make the manufacturing process more efficient.

Further, the present invention provides a gaming machine storage medium protection structure comprising a control board having a storage medium for a gaming machine and a board case for housing the control board, wherein the control board is a first board, A second substrate that is smaller than the first substrate disposed on the mounting surface of the first substrate, and the substrate case includes a transparent case base body that covers a back surface of the first substrate; A transparent case cover body assembled to the case base body so as to cover the mounting surface of one substrate, and an internal air space for housing the first substrate is formed by the assembled case cover body and the case base body. The case cover body is formed so as to be recessed from the outer side of the case and bulge toward the inner air space side, and further comprises a storage recess for disposing the second substrate from the outer side of the case. Detach to the body A transparent shielding member that shields the housing recess, and the second substrate is interposed between the first substrate and one or more support members that are erected on the mounting surface of the first substrate. The housing recess of the case cover body is integrally formed with a floor wall portion disposed between the first substrate and the second substrate. A storage medium protecting structure for a gaming machine, wherein the floor wall portion is formed with a through-hole through which the support member penetrates.

In such a configuration, the effect of preventing unauthorized access to the storage medium of the control board is further improved.

In the protective structure for a storage medium for gaming machines described above, the bottom wall portion is disposed between the first substrate and the second substrate in a non-contact manner with both the substrates. Proposed.

In such a configuration, it is possible to prevent the floor wall portion from interfering with the circuit on the first substrate when the case cover body is assembled to the case base body.

  The present invention also provides a gaming machine comprising the above-described protective structure for a storage medium for gaming machines.

  With such a configuration, the above-described operation and effects produced by the protection structure for the storage medium for gaming machines can be achieved.

It is provided separately from the first substrate 11 on which other electronic components are mounted. That is, the storage device ROM 21 and the storage device RAM 22 that should particularly prevent fraud are arranged separately from other electronic components.

Next, the above-described substrate case 3 will be described.
As shown in FIG. 3, the substrate case 3 includes a case base body 31 and a case cover body 32, and an internal air space 33 is formed by assembling the case cover body 32 to the case base body 31 (FIGS. 6 and 9). reference). The first substrate 11 is disposed in the internal air space 33. Here, since the first substrate 11 is disposed in the internal air space 33 such that the mounting surface 11a faces the case cover body 32, the first substrate 11 is formed by the case cover body 32 as shown in FIGS. The mounting surface 11 a is covered, and the back surface of the first substrate 11 is covered by the case base body 31.

  As shown in FIGS. 3 and 5, the case base body 31 has a substantially rectangular shallow box shape, and a flange that supports the first substrate 11 is formed inside the case base body 31. The case base body 31 communicates with each through hole at a position facing the through holes (not shown) opened at the four corners of the first substrate 11 in a state where the first substrate 11 is supported. Screw holes (not shown) are respectively formed. On the other hand, as shown in FIGS. 3 and 6, the case cover body 32 has a substantially quadrangular lid shape and includes four support protrusions 34 protruding from the four corners to the back side. Each support protrusion 34 comes into contact with the four corners of the first substrate 11 arranged inside the case base body 31 in a state where the case cover body 32 is assembled to the case base body 31. The support protrusion 34 has a bottomed cylindrical shape, and a hole penetrating the front and back is formed at the bottom, and this hole is a through hole of the first substrate 11 and a screw hole of the case base body 31. Communicate with.

  Furthermore, the case cover body 32 is formed with engaging protrusions 36 and 36 protruding leftward from the left edge thereof and elastic claw portions 35 and 35 protruding backward from the right edge thereof. On the other hand, the case base body 31 is formed with fitting holes 37, 37 for fitting the engagement protrusions 36, 36 of the case cover body 32 on the left side thereof, and the elastic claw 35 on the right side. , 35 are formed.

  As a procedure for assembling the case base body 31 and the case cover body 32, the first substrate 11 is supported on the case base body 31, as shown in FIG. Thereafter, as shown in FIG. 6, the case cover body 32 is assembled to the case base body 31 that supports the first substrate 11. At the time of this assembly, the engaging protrusions 36, 36 of the case cover body 32 are inserted into the fitting holes 37, 37 of the case base body 31, and the elastic claws 35, 35 of the case cover body 32 are attached. The case base body 31 is locked in the locking holes 38, 38. Thereby, the case cover body 32 is assembled to the case base body 31. In this state, a predetermined screw is screwed into the screw hole of the case base body 31 from the front side of the case cover body 32 through the hole of the support projection 34 and the through hole of the first substrate 11. Thus, the case cover body 32, the first substrate 11, and the case base body 31 are fastened. Further, the boundary between the case base body 31 and the case cover body 32 is bonded with a predetermined adhesive or the like. In this way, the case base body 31 and the case cover body 32 are joined to each other in a state where the first substrate 11 is disposed in the internal air space 33 in a non-detachable manner. After the joining, in order to open the case cover body 32 and the case base body 31, it is necessary to destroy at least one of them. For this reason, if it is illegally released, the trace remains, and it is possible to find such an illegal act relatively easily.

  3 and 6, the case cover body 32 is provided with a storage recess 41 that is recessed in a substantially square shape from the front side to the back side on the outer surface portion 32 a facing the mounting surface 11 a of the first substrate 11. Further, partition wall portions 39a and 39b projecting from the back side of the outer surface portion 32a are provided between the right edge of the case cover body 32 and the storage recess 41. Here, the housing recess 41 is provided near the left side edge of the case cover body 32, and the partition walls 39a and 39b are arranged side by side on the right side portion of the case cover body 32 (see FIG. 9). . The partition walls 39a and 39b are formed along the vertical direction of the case cover body 32, and are arranged inside the case base body 31 in a state where the case cover body 32 and the case base body 31 are assembled. It is close to the mounting surface 11a of the first substrate 11 (see FIG. 9). By providing such partition walls 39a and 39b, it is possible to prevent intrusion into the housing recess 41 if it is illegally intruded from the right side of the substrate case 3, such that the substrate case 3 The effect of preventing unauthorized intrusion from the right side portion to the storage recess 41 is remarkably improved.

  The storage recess 41 is formed so as to bulge to the back side of the outer surface portion 32a of the case cover body 32, and as shown in FIG. 6, the substantially square floor wall portion 41a and the outer surface portion 32a to the back side. The four side wall portions 41b and 41c are extended to reach the floor wall portion 41a. Here, the size of the storage recess 41 is set so that the second substrate 12 can be stored in the recessed air space. Further, the storage recess 41 includes the first substrate 11 disposed in the internal air space 33 in the state where the case cover body 32 and the case base body 31 are assembled, and various mounting components and floors mounted on the first substrate 11. The depth from the outer surface portion 32a to the floor wall portion 41a is set so as not to contact the wall portion 41a (see FIG. 9).

  As shown in FIGS. 6 and 7, four through holes 42 are formed in the floor wall 41 a of the storage recess 41 so as to penetrate the four support members 15 erected on the mounting surface 11 a of the first substrate 11. Has been. In the state where the case base body 31 and the case cover body 32 are assembled, the upper end portions of the four support members 15 erected on the first substrate 11 are connected to the floor wall portion 41 a via the through holes 42. Each protrudes above. The second substrate 12 is placed on the upper end of each support member 15 thus protruding, and the second substrate 12 is fastened to the support member 15 with a fixing screw. 11 and disposed inside the storage recess 41 as shown in FIG. In a state where the second substrate 12 is disposed in the storage recess 41, the second substrate 12 is adjacent to the floor wall portion 41 a of the storage recess 41 in a non-contact manner and is disposed on the mounting surface 12 a of the second substrate 12. The storage device ROM 21 and the storage device RAM 22 are accommodated in the storage recess 41 (see FIG. 9).

  Furthermore, the hole 43 for connectors is formed in the floor wall part 41a of the accommodation recessed part 41 like FIG. The connector hole 43 is for projecting the connector 23 disposed on the back surface of the second substrate 12 to the back side of the floor wall portion 41a. As described above, the connector 23 of the second substrate 12 is connected to the second substrate 12 via the connector hole 43 in a state where the second substrate 12 is arranged on the upper end of the support member 15 erected on the first substrate 11. It protrudes to the back side of the floor wall portion 41 a and is connected to the connector receiving portion 26 of the first substrate 11.

  The storage recess 41 is configured such that the left side wall 41c is a curved side wall 41c that curves in a convex manner toward the inner air space 33 side. The curved side wall portion 41c is easier to visually recognize the substantially entire area than the other side wall portion 41b when the storage concave portion 41 is viewed from the front side of the case cover body 32. Therefore, if a hole or the like is illegally formed in the curved side wall portion 41c, the illegal hole or the like can be easily found.

Here, in the present embodiment, only the left side wall 41c constituting the housing recess 41 is the curved side wall 41c, and the reason for this will be described below.
(1) In the control board unit 1, as shown in FIG. 1, the board case 3 (the case base body 31 and the case cover body 32) is formed in a substantially rectangular shape with the left-right direction as the longitudinal direction. Therefore, there is room for securing a sufficient space on the left and right sides of the storage recess 41, and the left and right side wall portions 41b and 41c of the storage recess 41 can be curved side wall portions. The left and right side wall portions 41b and 41c will be described in (2) below. On the other hand, since the vertical direction of the substrate case 3 is shorter than the horizontal direction, there is no room for securing a sufficient space above and below the storage recess 41. Therefore, in this embodiment, the upper and lower side wall portions 41b of the storage recess 41 are not curved side wall portions.
(2) When the control board unit 1 is attached to the slot machine 61, the attachment position is generally one of the A position, the B position, and the C position as shown in FIG. Here, the slot machine 61 includes a housing 62 that houses a reel 65 and a front door 63 that is attached to the housing 2 via a hinge mechanism so as to be openable and closable. A viewing window 66 is provided for viewing the image from the outside. In the slot machine 61, the A position is located immediately above the viewing window 65 on the back surface of the front door 63, and the B position is located directly above the reel 65 on the inner surface of the left side wall 62a of the housing 62. The position is located directly above the reel 65 on the inner surface of the back wall 62 b of the housing 62. When the control board unit 1 is attached to the position A, the control board unit 1 is attached with the left side portion (see FIG. 1) facing upward and the front side of the case cover body 31 facing the back of the slot machine 1. On the other hand, when mounting at the position B, the control board unit 1 is mounted with its left side (see FIG. 1) facing upward and the front side of the case cover body 31 facing right of the slot machine 1. On the other hand, when the control board unit 1 is attached to the position C, the control board unit 1 is attached with the left side (see FIG. 1) facing upward and the front side of the case cover body 31 facing the front side of the slot machine 1. Among these mounting positions, in particular, the B position and the C position are directly above the reel 65, so that the wiring and members connected to the reel 65 of the control board unit 1 mounted at the B position and the C position It overlaps with the lower part (the part near the right edge in FIG. 1) from the front side. Therefore, it is difficult to visually recognize the lower part of the control board unit 1 (the portion near the right edge in FIG. 1) with the front door 63 opened. For this reason, in the control board unit 1 of the present embodiment, the housing recess 41 is formed near the left side edge that is upward when attached to the slot machine 1 (see FIG. 1), and the front door 63 of the slot machine 1 is provided. In the opened state, the second substrate 12 of the storage recess 41 is easily visible. The storage recess 41 has a curved side wall 41b that is the upper side wall 41b when attached to the slot machine 1, and, as described above, when an illegal hole or the like is opened in the curved side wall 41b. It is easier to find. Further, as described above, the control board unit 1 is provided with the partition walls 39a and 39b of the case cover body 32 in the lower part (the portion near the right edge in FIG. 1) that is difficult to see when attached to the slot machine 1 (see FIG. 9), the effect of preventing intrusion reaching the storage recess 41 is significantly improved even when the board case 3 is illegally invaded from the right side of the substrate case 3. By providing the partition walls 39a and 39b in this manner, the disadvantage that the lower part of the control board unit 1 (the portion near the right edge in FIG. 1) is difficult to visually recognize when attached to the slot machine 61 is compensated. That is, in the control board unit 1 of the present embodiment, the storage recess 41 is provided in the upper part (the portion near the left edge in FIG. 1) that is easily visible when attached to the slot machine 61, and the upper side wall 41c is a curved side wall. On the other hand, partition portions 39a and 39b are provided in the lower portion (the portion near the right edge in FIG. 1) that is difficult to see when attached to the slot machine 61.

  Further, as shown in FIGS. 3 and 8, a flat plate-shaped shielding member 46 that shields the housing recess 41 is joined to the case cover body 32. The shielding member 46 closes the opening of the housing recess 41 in the outer surface portion 32 a of the case cover body 32. And the above-mentioned 2nd board | substrate 12 is accommodated in the airspace 47 (henceforth an accommodation airspace) shielded by the shielding member 46 (refer FIG. 9). Here, the shielding member 46 is bonded to the outer surface portion 32a of the case cover body 32 with a predetermined UV curable adhesive. Since this UV curable adhesive cannot be released after being cured, in order to remove the shielding member 46, it is necessary to destroy the shielding member 46 or the like. For this reason, if it is illegally released, the trace remains, and it is possible to find such an illegal act relatively easily. Further, since the shielding member 46 is flat, the height at which the shielding member 46 protrudes from the outer surface portion 32a of the case cover body 32 to the front side in a state of being adhered to the case cover body 32 is very small. is there. Thereby, the arrangement space for arranging the control board unit 1 of this embodiment in the gaming machine does not need to be increased by providing the shielding member 46, and is equivalent to the conventional configuration in which the shielding member 46 is not provided. The installation space is sufficient. That is, it can be said that the configuration including the flat shielding member 46 is advantageous in terms of the space for arranging the control board unit 1.

  The case base body 31, the case cover body 32, and the shielding member 46 described above can be manufactured by a manufacturing method in which a predetermined synthetic resin is injection molded, a manufacturing method in which press molding is performed, or the like. In this embodiment, the case base body 31, the case cover body 32, and the shielding member 46 are molded from the same synthetic resin and are made of a colorless and transparent synthetic resin. As a result, the case base body 31 and the case cover body 32 are assembled and further adhered to the shielding member 46 (the control board unit 1), and the first cover disposed in the internal air space 33 from the outside of the case cover body 32. One substrate 11 and the second substrate 12 disposed in the storage air space 47 can be visually recognized.

  As shown in FIG. 9, the substrate case 3 of the present embodiment is formed by an internal air space 33 formed by the case base body 31 and the case cover body 32, a storage recess 41 of the case cover body 32, and a shielding member 46. The storage airspace 47 is partitioned, and the storage airspace 47 is provided inside the internal airspace 33. In order to fit this board case 3, the control board 2 has a two-stage hierarchical structure including a first board 11 disposed in the internal airspace 33 and a second board 12 disposed in the storage airspace 47. Further, the second substrate 12 is mounted with a storage device ROM 21 and a storage device RAM 22 that store game control information such as game lottery. That is, the high-priority storage device ROM 21 and storage device RAM 22 to be protected from fraud are mounted on the second substrate 12 separately from other mounting components, and the second substrate 12 is stored in the internal air space 33. It is protected by a double structure with airspace 47.

In the control board unit 1 having such a structure, the case base body 31 is disposed on a gaming machine such as a slot machine via a predetermined fixing mechanism so that the outer surface portion 32a of the case cover body 32 can be visually recognized (FIG. 10). reference). The first board 11 and the second board 12 can be visually recognized from the front side of the case cover body 32 in a state where the control board unit 1 is disposed in the gaming machine.
In the state in which the control board unit 1 is arranged in the gaming machine in this way, as a fraudulent act of illegally accessing the storage device ROM 21 or the storage device RAM 22 of the second board 12, The shielding member 46 may be destroyed. However, in any case, since the fraudulent act from the surface side of the case cover body 32 remains in the shielding member 46 or the case cover body 32, it is easy to find out that the fraudulent act has been performed. it can. Therefore, fraud from the surface side of the case cover body 32 can be prevented.
Further, as another illegal act, an elongated metal device may be intruded from the side portion (any one of the top, bottom, left, and right sides) of the substrate case 3. Since various wirings and parts are arranged around the control board unit 1 in the state where it is arranged in the gaming machine, it is relatively difficult to find the trace of the side of the board case 3 described above. However, even when the second case 12 is intruded into the internal air space 33 from the side of the substrate case 3 as described above, the second substrate 12 is protected by the storage recess 41 and it is extremely difficult to enter the storage air space 47. It is. Therefore, unauthorized entry into the storage airspace 47 in which the second substrate 12 is disposed can be prevented. On the other hand, when entering the internal air space 33 from the side of the substrate case 3 and further entering the storage air space 47 of the storage recess 41, holes or the like are formed in the side walls 41b and 41c constituting the storage recess 41. It is most likely to open. However, when the side walls 41b and 41c are penetrated by making holes or the like in this way, traces generated in the side walls 41b and 41c can be found from the front side of the case cover body 32. For this reason, it is possible to prevent an illegal act of entering a hole or the like in the side wall portions 41 b and 41 c of the storage recess 41.
In particular, in the configuration of the present embodiment, as described above, partition wall portions 39a and 39b are provided in the portion near the right edge of the substrate case 3 that is relatively invisible when attached to the gaming machine (slot machine 61). Since the entry from the right side of the board case 3 to the storage recess 41 is prevented, the left side edge portion of the board case 3 on the opposite side is relatively easy to see when attached to the gaming machine. The left side wall 41c of the storage recess 41 is used as the curved side wall 41c, so that when a hole or the like is illegally opened into the curved side wall 41c, the trace can be found more easily. .

  As described above, the control board unit 1 of the present embodiment has a high function of protecting the second board 12 on which the storage device ROM 21 and the storage device RAM 22 are mounted, and ensures unauthorized access to the storage device ROM 21 and the storage device RAM 22. And can be stably prevented. And when the structure of a present Example is compared with the conventional structure of the patent document 1 mentioned above, the effect which prevents an illegal act is remarkably higher than this conventional structure. Furthermore, the control board unit 1 of the present embodiment is formed so that the housing recess 41 for housing the second board 12 is not in contact with the mounting surface 11a of the first board 11, so that There is no possibility of interfering with the circuit on the substrate as in the conventional configuration of 1.

  In the control board unit 1 of this embodiment, the first substrate 11 is arranged on the case base body 31, the case cover body 32 is assembled to the case base body 31 and fixed by screws or an adhesive, and then the case cover It can be manufactured by disposing the second substrate 12 in the housing recess 41 of the body 32 and bonding the shielding member 46. That is, the process of manufacturing the state in which the case base body 31 and the case cover body 32 are joined to the state where the first substrate 11 is disposed in the internal air space 33 (see FIGS. 5 and 6), It is possible to separate and separate the step of arranging the shielding member 46 and adhering the shielding member 46 (see FIGS. 7 and 8). Thereby, even when a relatively large amount of time is spent developing game control information stored in the storage device ROM 21, the manufacturing process is advanced to the process before the second substrate 12 is disposed (see FIGS. 5 and 6). Therefore, the manufacturing process of the control board unit 1 can be made efficient.

  In the above-described configuration of the present embodiment, the structure of the control board unit 1 realizes the gaming machine storage medium protection structure according to the present invention. The storage device ROM 21 and the storage device RAM 22 constitute a storage medium according to the present invention.

  On the other hand, as another example of the above-described embodiment, a configuration in which the shielding member 46, the case base body 31, and the case cover body 32 are formed in different transparent colors can be proposed. For example, the case base body 31 and the case cover body 32 are made transparent colors such as clear orange and clear yellow, and the shielding member 46 is made colorless and transparent. According to such a configuration, when a hole or the like is illegally opened in the side wall portions 41b and 41c of the storage recess 41 as described above, the shielding member 46 and the storage recess 41 have different transparent colors. It is easier to find from the outside of 46. Therefore, according to such a configuration of another example, it is easy to find a trace of fraud, and the effect of preventing the fraud is further improved. In addition, since the structure of this another example is the same structure as the Example mentioned above except having formed the shielding member 46, the case base body 31, and the case cover body 32 with a different transparent color as mentioned above, A description of the components is omitted.

  Further, in the configuration of the above-described embodiment, the one side wall portion constituting the housing recess of the case cover body is a curved side wall portion. However, the configuration is not limited to this, and a plurality of side wall portions are curved side wall portions. It can also be. For example, the other three side walls excluding the right side wall facing the partition walls 39a and 39b may be configured as curved side walls. Moreover, you may make it comprise all the four side walls as a curved side wall.

  Moreover, in the structure of the Example mentioned above, although it is the structure to which a flat shield member is applied, not only this but the shield member of various shapes can also be used. For example, a shape that curves to the front side or a shape that curves to the back side can be used. In addition, as above-mentioned as a shielding member, the structure which reduced the height which protrudes to the front side as much as possible is suitable on the relationship of installation space.

  Further, in the configuration of the above-described embodiment, the storage device ROM and the storage device RAM are mounted on the second substrate. However, the configuration is not limited thereto, and for example, the storage device ROM is mounted on the second substrate. Further, a configuration may be adopted in which a storage device RAM and a CPU are mounted. In this configuration, since the effect of preventing unauthorized access to the CPU is also improved, unauthorized acts can be further prevented.

  In this invention, it is not limited to the Example mentioned above, About the structure other than the above-mentioned Example, it can change and implement suitably within the range of the meaning of this invention.
