  Further, a restricting boss 879 for abutting and restricting the bending of the effect ROM substrate 90b is provided at a position corresponding to the second boss 821 projecting from the base member 801. By holding the effect control board 90a and the effect ROM board 90b with each other by the boss 879, the connection of board-side connectors BCN1 and BCN2 to be described later is restricted.

  In addition, an insertion hole is formed at a position corresponding to the board side connectors CN1 to CN5 etc. of the board case 800, and after the production control board 90a is accommodated in the board case 800, the board side connectors CN1 to CN5 etc. Once the connector is connected and attached once, a connector cover that can not be removed without leaving a trace may be attached.

  The effect control substrate 90a and the effect ROM substrate 90b are directly connected via the substrate connector BCN1 provided on the effect control substrate 90a and the substrate connector BCN2 provided on the effect ROM substrate 90b, and are integrated with each other. It is attached inside the cover member 802 in a state. Substrate side connectors CN1 to CN5 are provided on the back surface of the effect control substrate 90a. The board-side connectors CN1 to CN5 are connectors to which cable-side connectors (not shown) of cables connected to the game control board 40, the reel LED 55, the effect effect LED 52, and other effect devices are connected. A cable-side connector (not shown) is provided so as to be connectable.

A plurality of effect data ROMs 99a to 99d are attached to the rear surface of the effect ROM substrate 90b. Specifically, as shown in FIGS. 11C and 11D, the effect data ROMs 99a to 99d are detachably attached to the effect ROM substrate 90b via the ROM socket 910 provided on the back surface of the effect ROM substrate 90b. And connected to a wiring pattern (not shown) formed on the effect ROM substrate 90b. The ROM socket 910 includes a socket base 911 and mounting pieces 912a and 912b provided on the upper and lower portions of the socket base 911. Attachment pieces 912a, 912b includes a mount position (see FIG. 11 (D)) which effect data ROM99a~99d to the mounting state of being attached to the socket base 911, attaching the effect data ROM99a~99d respect to the socket base 911 , non-mounting position as a removable (see FIG. 11 (C)), provided rotatably in the socket base 911 between.

  Further, when the mounting pieces 912a and 912b are in the mounting position, the locking portions (not shown) provided on the mounting pieces 912a and 912b elastically lock on the locked portions formed on the socket base 911 Thus, the rotation to the non-attachment position is restricted. In addition, the locked state of the locking portion and the locked portion is extremely difficult to release with a human finger, and can be released through a special jig or the like (not shown). .

  Further, on the back surface of the effect ROM substrate 90b, a ROM cover 920 which is made of a translucent synthetic resin material and covers the effect data ROMs 99a to 99d attached to the ROM socket 910 is attached. The ROM cover 920 is formed in a square box shape whose front surface is open, and has a size capable of covering the effect data ROMs 99a to 99d together. Mounting pieces 921a to 921d for mounting are projected.

  Then, the rivets 922a to 922d attached to the attachment holes formed on the attachment pieces 921a to 921d are inserted into the insertion holes formed on the effect ROM substrate 90b, and the rivets 922a to 922a to protrude on the front side of the effect ROM substrate 90b. By squeezing the tip end of 922 d or the like to expand the diameter and restrict withdrawal (scaling), the effect ROM substrate 90 b is irremovably attached.

  Next, a method of storing the effect control board 90a and the effect ROM board 90b by the base member 801 and the cover member 802 configured as described above will be described based on FIG. 5, FIG. 6, and FIG.

  First, as shown in FIGS. 5 and 6, the effect control board 90a and the effect ROM board 90b are mounted on the mounting surface on which electronic components such as the board-side connectors CN1 to CN5 and the effect data ROMs 99a to 99d are mounted. The production ROM substrate 90 b is attached to the cover member 802 with the screws 875 and the production control substrate 90 a with the screws 875 while facing the front surface (inner surface) of the 802. Then, when the effect control board 90a is attached, the board side connector BCN1 is connected to the board side connector BCN2.

  The production control board 90a and the production ROM board 90b may be connected to the board side connectors BCN1 and BCN2 by attaching the production control board 90a after the production ROM board 90b is installed. You may attach to the cover member 802 in the state which connected and integrated BCN2.

  In this way, the effect control board 90a and the effect ROM board 90b are attached to the cover member 802 with the mounting surface on which the electronic components are mounted facing the cover member 802, so that the base member 801 covers the cover. Even if the member 802 is opened, the mounting surface on which the electronic component is mounted is not exposed unless the production control board 90a and the production ROM board 90b are removed from the cover member 802. It can be made to take time and effort as much as possible.

  Next, in order to assemble the cover member 802 to the base member 801, the locking pieces 870a and 870b of the cover member 802 are locked members 824a and 824a of the base member 801 as shown by two-dot chain lines in FIG. Insert into the locking hole 824h formed by 824b.

  At this time, even if the cover member 802 is inclined with respect to the base member 801 within a range of about 90 degrees, the locking pieces 870a and 870b cannot be inserted into the locking hole 824h, and the base member 801 If the cover member 802 is turned upright by rotating the cover member 802 by about 90 degrees (see the dashed line in FIG. 9A) and the bent piece 871b is parallel to the bottom plate 810, the cover member 802 can be inserted into the locking hole 824h. It becomes.

  Then, as shown in FIG. 9A, the bent piece 871b is inserted into the locking hole 824h, and the other end side of the cover member 802 is slightly rotated around the locking rod 825c. Since 871b passes through the locking hole 824h, the locking pieces 870a and 870b can be further pushed into the locking hole 824h (see the white arrow in the figure).

  At this time, as shown in the enlarged view of FIG. 9A, the support walls 825a and 825b are inserted into the notch grooves 872a to 872d, so that the locking pieces 870a and 870b are engaged with the base of the plate-like piece 871a. It is inserted into the stop hole 824h. In this state, by further rotating the cover member 802, the control protrusions 868a to 868d are fitted in the first groove 818e, and the cover member 802 is in a laid posture substantially parallel to the base member 801 (FIG. 9A). (See solid line position). That is, the cover member 802 is in the second closed position (a position where a part of the base member 801 is not covered by the cover member 802) shifted in the insertion direction (left direction) of the locking pieces 870a and 870b with respect to the base member 801. It becomes a lying posture.

  Since the cover member 802 cannot fit the restricting protrusions 868a to 868d into the first grooves 818e of the restricting grooves 818a to 818d unless the engaging pieces 870a and 870b are inserted into the engaging holes 824h, the second portion. It can not be placed in the closed position at the closed position.

  Next, as shown in FIG. 9B, the base member 801 is closed by sliding the cover member 802 with respect to the base member 801 in the direction opposite to the insertion direction of the locking pieces 870a and 870b (right direction). Position at the first closed position. Specifically, the outer surface of the right side wall 851a of the cover member 802 contacts the inner surface of the right side wall 811 of the base member 801, and the inner surface of the left side wall 851b of the cover member 802 contacts the left side wall 890 of the base member 801. The position at which the movement is restricted is set as the first closed position. When the first closed position is reached, the mounting holes 862 of the sealing pieces 861a and 861b are aligned with the screw holes 817 of the sealing pieces 815a and 815b, so that the one-way screw 816 can be screwed in and the base A cover-side welded portion 901 is disposed on the back side of the side welded portion 900 and can be welded.

  Further, by this movement, the restricting protrusions 868a to 868d move in the second groove 818f facing in the left-right direction, and are arranged at the end on the back side at the first closing position, so that the cover member 802 is opened in the opening direction (rear surface). Direction) is restricted.

  Furthermore, as shown in the enlarged view in FIG. 9B, the bent walls 871b abut on the locking rod 825c at the first closed position by the support walls 825a and 825b being detached from the notch grooves 872a to 872d. That is, the locking pieces 870a and 870b are maintained in the locked state inserted into the locking holes 824h while the cover member 802 moves between the second closed position and the first closed position. In the first closed position, the bending piece 871b abuts on the locking rod 825c to restrict sliding movement, thereby preventing deviation from the locking hole 824h.

  Therefore, in the first closed position, the control protrusions 868a to 868d formed on the upper and lower long sides of the cover member 802 are fitted in the second groove 818f, and the cover side welding is performed on the back side of the base welding portion 900. The portion 901 is disposed (see FIG. 9B). Further, the locking pieces 870a and 870b formed on the left short side are maintained in the state of being locked to the locking rod 825c, so that the movement of the cover member 802 relative to the base member 801 in the opening direction is restricted. Ru. That is, the restricting grooves 818a to 818d and the restricting projections 868a to 868d constitute the locking means of the present invention.

  Further, in the state of being located at the first closed position, the effect control board 90a and the effect ROM board 90b connected via the board-side connectors BCN1 and BCN2 are the second bosses 821 and 821 projecting from the base member 801. And the restriction boss 879 projecting from the cover member 802, the positions corresponding to the board-side connectors BCN 1 and BCN 2 are sandwiched from the front and back, thereby preventing the connection of the board-side connectors BCN 1 and BCN 2 from being released. Be done.

  In addition, the effect ROM board 90b cannot be removed from the cover member 802 unless the effect control board 90a is removed from the cover member 802. Therefore, even if the cover member 802 is removed from the base member 801, the program is executed. The production ROM board 90b on which the production data ROMs 99a to 99d in which data and the like are stored cannot be easily removed. Furthermore, since the upper and lower ends of the effect ROM substrate 90b are supported from the front side by the support pieces 819a and 819b of the base member 801, bending or the like of the substrate is prevented.

  Next, as shown in FIGS. 5 and 6, a one-way screw 816 is attached to the attachment hole 862 of the sealing pieces 861 a and 861 b from the back side, and is screwed into the screw holes 817 of the sealing pieces 815 a and 815 b. The one-way screw 816 is a conventionally well-known one-way screw that can be rotated in a direction in which the screw is attached by a tool such as a screwdriver, but cannot be rotated in a direction in which the screw is removed.

  That is, when the one-way screw 816 attached to the attachment hole 862 is screwed into the screw hole 817, it is very difficult to remove the one-way screw 816 from the screw hole 817 and to open the cover member 802 to the base member 801. A stop state is configured. When the sealed state is configured, for example, the connecting piece 863b is cut with a tool such as a nipper, or a part of the cover member 802 or the base member 801 is broken, and the related portion related to sealing is not broken. As long as the sealing state is released, the cover member 802 can not be opened.

  Therefore, when the cover member 802 is opened after being in the sealed state, there is always a trace that the related part related to the sealing is destroyed, and thus the cover member 802 may be opened illegally. It becomes possible to confirm that.

  Further, when the substrate case 800 in a sealed state is attached to the attachment plate 360, the one-way screw 816 attached to the sealing pieces 815a, 815b, 861a, 861b is further screwed to form the attachment plate 360. By screwing into the screw holes (not shown), the substrate case 800 can not be removed from the mounting plate 360 without leaving a trace. That is, the sealing pieces 815a, 815b, 861a, 861b and the one-way screw 816 constitute an attachment means.

  Further, as shown in FIG. 12, the cables connected to the board-side connectors CN1 to CN5 are connected to the notch recess 301 and the mounting plate 360 of the cable cover portion 300 in a state where the board case 800 is attached to the mounting plate 360. From the gap formed between the two. As described above, in the state where the substrate case 800 is attached to the attachment plate 360, a gap is formed between the notch recess 301 and the attachment plate 360, and a plurality of cables are inserted into the gap. In addition, it is formed at a position away from the rendering data ROMs 99a to 99d to the left. Furthermore, since the front and rear positions of the gap formed between the notch recess 301 and the mounting plate 360 and the presentation data ROMs 99a to 99d are different, it is possible to access the presentation data ROMs 99a to 99d from this gap. It is considered difficult.

  Next, welding of the base-side welding portion 900 and the cover-side welding portion 901 will be described based on FIGS. 14 to 16.

  As shown in FIGS. 14A and 14B, the base-side welded portion 900 is made of a plate-like member, and has a restricting portion 902a bent toward the rear side at the front end and a left side from the rear end of the restricting portion 902a. A hook-shaped restricting piece 902 is formed of a covering portion 902 b which is bent so as to be folded back toward. Further, an opening 907a is formed on the side of the right side wall 811 in the base-side welded portion 900, and connecting portions 908a and 908b whose upper and lower dimensions are shorter than the base-side welded portion 900 are formed at upper and lower positions of the opening 907a. ing.

  A protrusion 904 is formed in a reverse U shape in a front view on the back surface of the base side welding portion 900 and the connection portions 908a and 908b, that is, the welding surface with the cover side welding portion 901. The ridges 903 are formed on the

  As shown in FIGS. 14C and 14D, the cover-side welded portion 901 is made of a plate member. An opening 907b is formed on the right side wall 851a side of the cover-side welded portion 901, and connecting portions 909a and 909b having shorter vertical dimensions than the cover-side welded portion 901 are formed at the upper and lower positions of the opening 907b. .

  Further, the concave groove 905 capable of accommodating the projection 904 is viewed from the front at a position corresponding to the projection 904 on the front surface of the cover-side welding portion 901 and the connecting portions 909a and 909b, that is, the welding surface with the base-side welding portion 900. In addition to being formed in a reverse U-shape, in a region inside the concave groove 905, two projections 906a and 906b are formed in a reverse U-shape in a front view.

  The cover-side welded portion 901 and the base-side welded portion 900 configured as described above are ultrasonically welded using, for example, an ultrasonic welder. Specifically, as shown in FIG. 15, when the cover member 802 is disposed at the second closing position, the cover-side welding portion 901 and the base-side welding portion 900 are disposed to face each other. At this time, the protrusion 904 is disposed at a position corresponding to the recessed groove 905, and the top of the protrusion 906 abuts on the raised portion 903 which is the welding surface of the base-side welded portion 900.

  In this state, although not particularly shown, the cover side welding portion 901 is set on a predetermined installation surface of a jig (not shown) of the welding machine, and the base side welding portion 900 is pressed against the jig (not shown). And ultrasonically vibrate. At this time, the welding surface of the cover-side welding portion 901 and the welding surface of the base-side welding portion 900 are not in direct contact with each other, but only the top of the projection 906 is in contact with the welding surface of the raised portion 903. Since the tops of the projections 906 are melted out, ultrasonic vibration is applied while the welding surface of the cover-side welding portion 901 formed in a flat surface shape is in direct contact with the welding surface of the base-side welding portion 900. Compared to the case, it is possible to bring about a uniform molten state, and it is possible to obtain a stable welding strength, and the heat generation at the welded portion is abrupt, so that the welding can be performed in a short time. It becomes hard to get up.

  As described above, the welding surface of the cover-side welding portion 901 and the welding surface of the base-side welding portion 900 are melted and welded to be integrated with each other, so that it is extremely difficult to separate them (FIG. 15 ( B) Middle thick line part shows a welding part). Since the welding surface of the cover side welding portion 901 and the welding surface of the base side welding portion 900 are fixed in this manner, the sliding movement of the cover member 802 with respect to the base member 801 is restricted. It becomes impossible to release the locked state of 802. That is, unless the welding state between the welding surface of the cover-side welding portion 901 and the welding surface of the base-side welding portion 900 is released, a sealed state in which the cover member 802 can not be opened is formed.

  Here, for example, in the case where the cover-side welding portion 901 and the base-side welding portion 900 are peeled off by forcibly sliding the cover member 802 in the locking release direction with respect to the base member 801, the opposing surfaces are mutually opposed. Since it is melted and deformed, scratches and deformation marks remain on both the cover-side welded portion 901 and the base-side welded portion 900, that is, both the base member 801 and the cover member 802, so that the cover member 802 is opened ( It can be surely found that it may have been opened.

  In FIG. 16, for example, from a used game machine etc., two substrate cases A and B sealed by welding as described above are obtained, and one of these two substrate cases A and B is used on the base side. The base member 801 in which the welded portion 900 is not destroyed is acquired, and the cover member 802 in which the cover-side welded portion 901 is not destroyed is acquired from the other, and illegal production data is obtained by the base member 801 and the cover member 802. After accommodating effect ROM substrate 90b on which ROMs 99a to 99d are mounted, an example of a fraudulent act of welding cover side welding portion 901 and base side welding portion 900 to newly form a sealed state is shown. As shown in FIG. 16A, the acquired substrate cases A and B are welded and sealed by the above-described welding methods, respectively.

  Here, when acquiring the base member 801 in which the base side welding part 900 is not destroyed from one board case A, the joining surface from the side surface of the base side welding part 900 to the welding surface of the cover side welding part 901 is obtained. It is preferable to insert a cutter or the like in between, but in the sealed state, since the left side surface of the cover side welded portion 901 and the base side welded portion 900 is covered with the regulating portion 902a, the cover side welded portion 901 and It is extremely difficult to insert a cutter or the like between the joint surfaces with the base-side welded portion 900.

  Therefore, as indicated by a one-dot chain line in FIG. 16B, it is conceivable to remove a part of the cover-side welding portion 901 with a cutting machine such as a router (not shown). However, even in this case, the right end of the welded portion of the cover-side welded portion 901 is approaching the covering portion 902b, so that even if it is cut by a router, it is inserted between the covering portion 902b and the base-side welded portion 900. The remaining welded portion 901P will remain.

  In addition, when acquiring the cover member 802 from which the cover-side welded portion 901 is not broken from the other substrate case B, a cutter or the like is similarly provided between the side surface of the cover-side welded portion 901 and the base-side welded portion 900 between the joining surfaces. It is preferable to insert and peel, but in the sealed state, it is extremely difficult to insert a cutter or the like because the cover-side welding portion 901 and the left side surface of the base-side welding portion 900 are covered by the regulation portion 902a. There is.

  Therefore, as shown by a dashed-dotted line in FIG. 16C, it is conceivable to remove the cover-side welded portion 901 from the front side by, for example, a cutting machine such as a router (not shown). In this case, the entire area of the welded portion in the welded plate portion 261 can be cut by a router.

  Then, as shown in FIG. 16D, the base member 801 of the substrate case A and the cover member 802 of the substrate case B obtained by removing one of the cover-side welding portion 901 and the base-side welding portion 900. When forming the sealed state by accommodating the effect ROM substrate 90b on which the incorrect effect data ROMs 99a to 99d are mounted, the remaining welded portion 901P remains in the base-side welded portion 900 of the substrate case A, A part of the cover-side welding portion 901 of the cover member 802 of the substrate case B must be cut in advance. As a result, since the cut portion C remains between the tip of the cover-side welded portion 901 and the remaining welded portion 901P, it can be visually confirmed that the sealed state has been formed improperly. In particular, since the base-side welded portion 900 is formed of a transparent synthetic resin material, the base-side welded portion 900 is transparent even if the cut portion C is disposed so as to overlap the front end side portion of the covering portion 902b. And the cutting part C can be confirmed.

  As described above, the two board cases A and B are obtained from the used gaming machine, and the base member 801 in which the base-side welded portion 900 is not destroyed is obtained from one of the two board cases A and B. After the cover member 802 whose cover side welded part 901 is not broken is acquired from the other side and the effect ROM substrate 90b on which the illegal effect data ROMs 99a to 99d are mounted is accommodated by the base member 801 and the cover member 802, Even when trying to form a new sealed state by welding the cover-side welded portion 901 and the base-side welded portion 900, the trace remains in some form, so it is surely found that there is a possibility of fraud can do.

  Further, at least one of the base member 801 and the cover member 802 is provided with an encapsulating portion in which the dye is encapsulated by releasing the sealing, and the encapsulating portion is released by releasing the sealing between the base member 801 and the cover member 802. Is broken and the internal dye oozes out so that the dye adheres to the base member 801 and the cover member 802. By such a configuration, it is difficult to reuse the base member 801 and the cover member 802. It becomes.

  Further, in the present embodiment, projections 906a and 906b having a substantially reverse U-shape in a front view are formed on the cover-side welding part 901, and the welding parts are formed by dissolving the projections 906a and 906b. As a result, the weld formed by being melted and crushed at the time of welding also has a substantially inverted U shape when viewed from the front, and the cover-side weld 901 and the base-side weld 900 are transparent synthetic resins. By being formed of a material, the welded portions in a substantially reverse U-shape in front view can be visually recognized from the outside. On the other hand, when the sealing state is formed by the injustice as shown in FIG. 16, the projections 906a and 906b have been removed by cutting, and the welding surface of the cover-side welding portion 901 having a flat surface is mutually formed. Since the welded surface of the base-side welded portion 900 is ultrasonically welded, the shape of the welded portion after curing is different from a regular welded portion formed in a substantially inverted U shape when viewed from the front, so the welded after curing It is possible to confirm that there is a possibility that an illegal act has been performed by the difference in the shape of the parts. In addition, the welding between the flat surfaces can not provide a uniform molten state, and can not obtain stable welding strength.

  In order to release the sealed state, for example, the connecting piece 863b of the sealing pieces 861a and 861b is cut with a tool such as a nipper to release the connected state between the tubular portion 863a and the cover member 802, and the cover side After the connecting portions 908a, 908b, 909a, and 909b between the welded portion 901 and the base-side welded portion 900 are cut by a cutter or the like, the cover member 802 is slid toward the second closing position with respect to the base member 801. That is, the locking pieces 870a and 870b are slid toward the direction of inserting into the locking holes 824h. As a result, the restricting protrusions 868a to 868d move to the first groove 818e (see FIG. 9B), so that the restriction of opening the cover member 802 by the restricting grooves 818a to 818d is released.

  Next, from the second closed position where the locking pieces 870a and 870b are inserted deeply into the locking hole 824h, the right end of the cover member 802 is rotated around the locking rod 825c, and the cover member 802 is moved relative to the base member 801. When the standing posture is raised, the cover member 802 is slid along the base member 801 in the standing posture, whereby the bent piece 871b can be extracted from the locking hole 824h.

  Thus, in the sealed state, the substrate case 800 is in the connected state of the connection pieces 863b of the sealing pieces 816a and 816b, the connection parts 908a, 908b, 909a and 909b of the base side welding part 900 and the cover side welding part 901. Sealed state unless one of the connection state, the fitting state of the control protrusions 868a to 868d into the control grooves 818a to 818d, and the locking state of the locking pieces 870a and 870b and the locked members 824a and 824b is released. Can not be released. When either of these is canceled, a trace remains because a part of the base member 801 or the cover member 802 is broken, cut, or deformed.

  Further, in the sealed state, as shown in FIG. 11, a ROM cover 920 that covers the production data ROMs 99a to 99d is attached to the production ROM board 90b by rivets 922a to 922d, thereby providing a simple structure for production. Removal of the data ROMs 99a to 99d can be restricted.

  In this embodiment, for example, when the production data ROMs 99a to 99d are inspected, the ROM cover 920 can be removed by cutting the rivets 922a to 922d, and the ROM cover 920 can be attached again using the rivets 922a to 922d. In other words, the ROM cover 920 can be reused, but the ROM cover 920 cannot be removed unless the ROM cover 920 is destroyed, that is, the ROM cover 920 cannot be reused once removed. . Also, if the ROM cover 920 is provided with a plurality of attachment portions and attached to the effect ROM substrate 90b using the attachment portions, the ROM cover 920 cannot be removed unless the attachment portions are destroyed, but other attachment portions are used. The ROM cover 920 may be reusable by being attached to the effect ROM board 90b.

  In this embodiment, the effect ROM board 90b is arranged at a position where the interval between the inner surface of the back plate 850 of the cover member 802 and the outer surface of the ROM cover 920 is such that the effect data ROMs 99a to 99d cannot be removed. 11B, even if the rivets 922a to 922d are cut and the ROM cover 920 is removed from the effect ROM board 90b, the ROM cover 920 is attached to the inner surface of the back plate 850 of the cover member 802. Since it cannot be shifted from the covering position where it abuts and covers the effect data ROMs 99a to 99d, it is extremely difficult to remove the effect data ROMs 99a to 99d.

  In this embodiment, the production data ROMs 99a to 99d are covered by the ROM cover 920. However, the present invention is not limited to this, and the board case 800 may be covered by the ROM cover 920. The effect ROM substrate 90b may be disposed at a position where the distance between the inner surface of the back plate 850, which is the inner surface, and the upper surface of the effect data ROMs 99a to 99d can not be removed for the effect data ROMs 99a to 99d.

  Specifically, for example, as shown in FIG. 17A, in the sealed state, the back plate 850 of the cover member 802 is disposed close to the effect data ROMs 99a to 99d, and the mounting pieces 912a and 912b are arranged. When it is going to rotate from the attachment position to the non-attachment position, the attachment pieces 912a and 912b may come into contact with the inner surface of the back plate 850 and cannot be made to rotate to the non-attachment position.

  Alternatively, even when the effect data ROMs 99a to 99d are removed from the socket base 911, the effect data ROMs 99a to 99d can be rotated from the inner surface of the socket base 911 to the back plate 850 even if the effect data ROMs 99a to 99d are removed from the socket base 911 99d may not be extracted. In this way, in the state of being housed in the substrate case 800, it becomes impossible to remove the effect data ROMs 99a to 99d attached to the effect ROM substrate 90b by the inner surface of the substrate case 800.

  In addition, as described above, the effect ROM is such that the distance between the inner surface of the back plate 850, which is the inner surface of the substrate case 800, and the upper surfaces of the effect data ROMs 99a to 99d is not such that the effect data ROMs 99a to 99d cannot be removed. In the case where the substrate 90b is disposed, for example, as shown in FIG. 17B, in the sealed state, a projecting portion 853 that protrudes inward from the inner surface of the back plate 850 of the substrate case 800 is formed. The effect ROM board 90b may be arranged at a position where the interval between the inner surface of the projecting portion 853 and the upper surfaces of the effect data ROMs 99a to 99d is such that the effect data ROMs 99a to 99d cannot be removed.

  In this embodiment, the ROM socket 910 is attached to the socket base 911 by operating the attachment pieces 912a and 912b. However, the present invention is not limited to this, for example, as shown in FIG. As shown in the figure, when the connection terminal 99f extending from the production data ROM 99e is inserted into the socket base 911A attached to the production ROM board 90b, the back which is the inner surface of the board case 800 is provided. The effect ROM substrate 90b may be disposed at a position where the distance between the inner surface of the plate 850 and the upper surface of the effect data ROM 99e can not be removed from the effect data ROM 99e.

  That is, even if the effect data ROM 99e is taken out of the socket base 911A, the effect data ROM 99e may be in contact with the inner surface of the back plate 850 so that the connection terminal 99f can not be pulled out of the socket base 911A.

  Further, since the ROM socket 910 requires a special jig for removing the production data ROMs 99a to 99d, the production data attached to the production ROM board 90b housed in the board case 800 without opening the board case 800. It becomes impossible to remove the ROMs 99a to 99d.

  Further, in this embodiment, in the sealed state, sealing pieces 815a, 815b, sealing pieces 816a, 816a as sealing means for sealing so that the base member 801 and the cover member 802 cannot be opened without leaving a trace. 816 b and one way screw 816, base side welding portion 900 and cover side welding portion 901, restricting grooves 818 a to 818 d and restricting projections 868 a to 868 d, locking pieces 870 a and 870 b and locked members 824 a and 824 b Sealed around the perimeter. Specifically, at least one sealing means is provided on each of the upper side, the lower side, the left side, and the right side of the substrate case 800. At least a part of these sealing means includes a base-side welded portion 900 provided on the base member 801 via the connecting portions 908a and 908b, and a cover provided on the cover member 802 via the connecting portions 909a and 909b. The base member 801 and the cover member 802 are sealed so that they cannot be opened by welding the base side weld portion 900 and the cover side weld portion 901.

  Therefore, since the base member 801 and the cover member 802 are sealed by the sealing means around the periphery of the substrate case 800, it becomes difficult to form a gap between the base member 801 and the cover member 802. The effect data ROMs 99a to 99d attached to the effect ROM board 90b are removed without using the gap formed between the cover member 802 and the board case 800, and replaced with unauthorized parts. Can be prevented. Further, since sealing is performed by welding the base-side welded portion 900 and the cover-side welded portion 901, sealing between the base member 801 and the cover member 802 is strengthened.

  In this embodiment, the base side welded portion 900 and the cover side welded portion 901 are welded so that the base member 801 and the cover member 802 cannot be opened, but the present invention is limited to this. For example, at least a part of the sealing means is a base side adhesive portion provided on the base member 801 via the connecting portions 908a and 908b. And the cover-side adhesive portion 901 provided on the cover member 802 via the connecting portions 909a and 909b, and by bonding the base-side adhesive portion 900 and the cover-side adhesive portion 901, the base member 801 and the cover The member 802 may be sealed so that it cannot be opened.

  In this embodiment, the sealing means is provided at a plurality of locations around the periphery of the substrate case 800. However, the present invention is not limited to this, and the base member 801 and the cover are provided over the entire periphery of the substrate case. You may make it seal so that it cannot open by welding or adhere | attaching the junction part with the member 802. FIG.

  Specifically, like the substrate case 800A as a modified example shown in FIG. 19, connecting pieces 930 and 931 continuous over the entire circumference of each of the base member 801A and the cover member 802A are extended outward, and these connecting pieces The sealed state may be formed by bonding 930 and 931 to each other by welding or adhesion. In this way, no gap is formed between the base member 801A and the cover member 802A. .

  Further, a concave portion 932 and a convex portion 933 are formed on the joint surfaces of the joint pieces 930 and 931, respectively, and the joint pieces 930 and 931 are welded in a state where the convex portion 933 is fitted to the concave portion 932, thereby forming a more gap. Even if there is a welding leak, the gap between the concave portion 932 and the convex portion 933 is hardly formed.

  Further, in this case, the elastic locking claws 934 are formed from a plurality of locations on the inner surface of the side wall of the cover member 802A toward the base member 801A, and at positions corresponding to the elastic locking claws 934 on the inner surface of the side wall of the base member 801A, The elastic locking claw 934 forms a locking portion 935 that can be elastically locked, and the elastic locking claw 934 is elastically locked to the locking portion 935 when the base member 801A and the cover member 802A are assembled. You may do so.

  Since these elastic locking claws 934 and locking portions 935 are locked inside the substrate case 800A, once the base member 801A and the cover member 802A are assembled and locked, the base member 801A. Unless the cover member 802A is destroyed, the locked state cannot be released, that is, the base member 801A and the cover member 802A cannot be opened. That is, the elastic locking claws 934 and the locking portion 935 constitute a sealing means for sealing the base member 801A and the cover member 802A so as not to be opened without leaving a trace.

  Further, in the present embodiment, the board case 800 is an example of the entrance restricting means for restricting entrance from between the base member 801 and the cover member 802, the outer side walls 812a and 812b, the outer side walls 852a and 852b, and the guide wall 867a, Although 867b, right side wall 811 and right side wall 851a, left side wall 890 and left side wall 851b are described, the present invention is not limited to this, and a structure formed on the base member 801 or the cover member 802 is used. For example, as shown in a substrate case 800B as a modified example shown in FIG. 20, the entry restriction wall 940 is provided separately from the base member 801B and the cover member 802B. The means may be formed.

  Specifically, the entry restriction wall 940 has a size that can be accommodated in the substrate case 800B, and is disposed along the inner surface of the side wall of the base member 801B or the cover member 802B when accommodated. It is formed in a square frame shape. Therefore, as shown in FIG. 20C in particular, in the sealed state, the entry restriction wall 940 is disposed close to the inside of the joint between the base member 801B and the cover member 802B, so that the base member 801B and the cover Even if a gap is generated in the joint by twisting member 802B, foreign matter such as a wire can be made to enter inside or the effect data ROMs 99a to 99d can be taken out from the gap due to the presence of the entry control wall 940. Can not

  By doing in this way, it can control that foreign materials, such as a wire, enter the inside, without complicating the structure of base member 801B and cover member 802B.

  Further, in this embodiment, the base-side welded portion 900 and the cover-side welded portion 901 as sealing means are formed only at one place on the right side of the substrate case 800, but the present invention is limited to this. 20A and 20B, a plurality of base-side welded portions 950 and cover-side welded portions 951 as sealing means may be provided over the periphery of the substrate case 800.

  As described above, in the slot machine 1 as the embodiment of the present invention, a circuit is mounted with effect data ROMs 99a to 99d as electronic parts related to the control for giving the player an advantage. A effect ROM substrate 90b as a substrate, a substrate case 800 for storing the effect ROM substrate 90b, sealing pieces 815a and 815b as sealing means for sealing the substrate case 800 so that the substrate case 800 can not be opened without leaving a trace Retaining pieces 816a and 816b and one way screw 816, base side welding portion 900 and cover side welding portion 901, restricting grooves 818a to 818d and restricting projections 868a to 868d, locking pieces 870a and 870b and engaged members 824a and 824b, Effect data ROMs 99a to 99 mounted on the effect ROM substrate 90b housed in the substrate case 800. As removal restriction means for restricting the removal of, and a ROM cover 920.

  By doing so, the removal of the production data ROMs 99a to 99d attached to the production ROM board 90b housed in the board case 800 is restricted, so that the board case 800 is attached to the production ROM board 90b without opening. It is possible to prevent the rendered effect data ROMs 99a to 99d from being removed and replaced with unauthorized parts.

  Further, in the present embodiment, the ROM cover 920 as a covering member attached to the effect ROM substrate 90b and covering at least a part of the effect data ROMs 99a to 99d is applied as the restricting means, and the substrate has a simple structure. The removal of the effect data ROMs 99a to 99d mounted on the effect ROM substrate 90b housed in the case 800 can be restricted.

  In this embodiment, the ROM cover 920 is directly attached to the effect ROM board 90b. However, the ROM cover 920 may be attached via an attachment member provided on the effect ROM board 90b.

  Further, in this embodiment, by including the ROM socket 910 which requires a special jig (not shown) for removing the effect data ROMs 99a to 99d as the restricting means, it is special for removing the effect data ROMs 99a to 99d. Since a jig is required, it is impossible to remove the effect data ROMs 99a to 99d mounted on the effect ROM substrate 90b stored in the substrate case 800 without opening the substrate case 800.

  Further, as the restricting means, in the state where the effect ROM board 90b is housed in the substrate case 800, the interval between the inner surface of the substrate case 800 and the upper surfaces of the effect data ROMs 99a to 99d cannot be removed. A structure (see FIGS. 11A, 11B, 17A, 18B, 18A, and 18B) in which the effect ROM substrate 90b is disposed at the interval may be used. With this structure, it is impossible to remove the effect data ROMs 99a to 99d mounted on the effect ROM substrate 90b by the inner surface of the substrate case 800 in the state of being housed in the substrate case 800.

  Further, as a restricting means, the projection portion 853 is provided at a position corresponding to the rendering data ROMs 99a to 99d inside the substrate case 800, and the projection ROM 85b and the rendering in the state where the rendering ROM substrate 90b is stored in the substrate case 800. The production data ROMs 99a to 99d may have a structure in which the production data ROMs 99a to 99d cannot be removed (see FIG. 17B). This makes it impossible to remove the production data ROMs 99a to 99d mounted on the production ROM board 90b.

  Further, in the present embodiment, the substrate case 800 is composed of a base member 801 as a base body and a cover member 802 as a cover body, and the effect ROM substrate 90b is accommodated between the base member 801 and the cover member 802; The gap between the base member 801 and the cover member 802 is not formed. However, the gap may be formed. In the structure in which the gap is formed, the gap is larger than the thickness of the production data ROMs 99a to 99d. It is preferable to reduce the size, and by doing so, it becomes impossible to exchange the production data ROMs 99a to 99d attached to the production ROM board 90b through the gap between the base member 801 and the cover member 802.

  In this embodiment, the production ROM board 90b and the production ROM board 90b as circuit boards on which the production data ROMs 99a to 99d as electronic parts related to the control for giving the player an advantage are attached. Sealing pieces 815a and 815b, sealing pieces 816a and 816b and one-way screws 816 as sealing means for sealing the substrate case 800 so that the substrate case 800 can not be opened without leaving a trace, and the base-side welding portion 900 and cover side welding portion 901, restricting grooves 818a to 818d, restricting projections 868a to 868d, locking pieces 870a and 870b and locked members 824a and 824b, and the sealing means is provided around the substrate case 800. And at least a part of the sealing means is connected to the base member 801 via the connecting portions 908a and 908b. A base-side welded portion 900 as a provided base-body-side welded portion, and a cover-side welded portion 901 as a cover-body-side welded portion provided on the cover member 802 via connecting portions 909a and 909b. The base member 801 and the cover member 802 are sealed so that they cannot be opened by welding the welded portion 900 and the cover-side welded portion 901 (see FIG. 9).

  By doing this, since the base member 801 and the cover member 802 are sealed by the sealing means around the periphery of the substrate case 800, it is difficult to form a gap between the base member 801 and the cover member 802 Using the gap formed between the base member 801 and the cover member 802, the production data ROMs 99a to 99d attached to the production ROM board 90b are removed without opening the board case 800, and illegal parts are removed. Can be prevented from being replaced. Further, at least a part of the sealing means is a base-side welding portion 900 provided on the base member 801 via the connection portions 908a and 908b, and a cover side provided on the cover member 802 via the connection portions 909a and 909b. Since the base member 801 and the cover member 802 are sealed by welding the welded portion 901, the base member 801 and the cover member 802 are firmly sealed.

  In the present embodiment, the base side welding portion 900 provided on the base member 801 via the connecting portions 908a and 908b, and the cover side welding portion 901 provided on the cover member 802 via the connecting portions 909a and 909b, The base side welding portion 900 provided on the base member 801 via the connecting portions 908a and 908b and the cover side welding portion provided on the cover member 802 via the connecting portions 909a and 909b. The base member 801 and the cover member 802 are firmly sealed even with such a configuration.

  In addition, the sealing unit seals the base member 801 and the cover member 802 so as not to be opened by welding or bonding the bonding portion between the base member 801 and the cover member 802 over the entire circumference of the substrate case 800. In this case, the joint between the base member 801 and the cover member 802 is welded or bonded all around, so that a gap is formed between the base member 801 and the cover member 802. Absent.

  Further, that the base member 801 and the cover member 802 are sealed by the sealing means around the periphery of the substrate case 800 does not necessarily have to be sealed all around, and the substrate case 800 as in the present embodiment. Any structure may be used as long as the base member 801 and the cover member 802 are sealed by a plurality of sealing means provided at intervals around the periphery.

  The sealing means seals the base member 801 and the cover member 802 so that they cannot be opened by sticking a seal (a so-called sealing seal) that leaves a trace when peeled over the entire circumference of the substrate case 800. It is good also as a structure, and since the joining part of the base member 801 and the cover member 802 extends over the whole periphery and the seal | sticker which leaves a trace when it peels off is affixed, a base member is left without leaving a trace. It becomes impossible to form a gap between 801 and the cover member 802.

  Further, it is preferable that a plurality of sealing means are provided around the periphery of the substrate case 800, and by doing so, the joint portion between the base member 801 and the cover member 802 is welded or bonded at a plurality of locations over the entire circumference. Therefore, it is difficult to form a gap between the base member 801 and the cover member 802. In particular, it is preferable that at least one sealing means be provided on each side of the substrate case 800. With such a configuration, a gap is formed between the base member 801 and the cover member 802. Can be prevented more reliably.

  Further, the sealing means forms a substantially C-shaped groove portion in cross-sectional view on one entire long side of the base member 801 or the cover member 802, and fits in the groove portion on one entire long side of the base member 801 or the cover member 802. The base member 801 and the cover member 802 may be sealed by forming a rail portion to be joined and fitting the rail portion into the groove portion. With such a configuration, the base member 801 and the cover are covered. It is possible to prevent a gap from being formed at a long-side joint where a gap is easily formed between the member 802 and the member 802.

  Further, in the present embodiment, the board case 800 serves as an entrance restricting means for restricting entrance from between the base member 801 and the cover member 802, the outer walls 812a, 812b, the outer walls 852a, 852b and the guide walls 867a, 867b, By providing the right side wall 811 and the right side wall 851a and the left side wall 890 and the left side wall 851b, entry from the gap formed between the base member 801 and the cover member 802 is restricted, so the substrate case 800 is opened. It is possible to prevent the production data ROMs 99a to 99d mounted on the production ROM board 90b without being replaced with unauthorized parts.

  Also, the outer wall 852a, 852b, etc. of the cover member 802, the vicinity of the joint between the cover member 802 and the base member 801 may be made thicker than other parts, such as the back plate 850, and such a configuration. Thus, even when the substrate case 800 is twisted, it is difficult to form a gap between the base member 801 and the cover member 802.

  Further, in the present embodiment, when the base member 801 and the cover member 802 are integrally attached, the substrate case 800 can not be reused when opened after that, but a spare sealing portion is provided. The substrate case 800 may be reused by allowing the substrate case 800 to be sealed after being opened by using a spare sealing portion.

  In this embodiment, the substrate case 800 is configured to be attached to the mounting plate 360 installed on the front door 1b so as not to be removed without leaving a trace. It is good also as a structure directly attached with respect to 1b or the housing | casing 1a so that removal is impossible, without leaving a trace. In addition, by providing a plurality of sealing portions for attaching to the mounting plate 360, the front door 1b, the housing 1a, etc., and making it possible to attach using a spare sealing portion after removal, the substrate case 800 It is good also as a structure which can be utilized again.

  In the present embodiment, a rewritable flash ROM is used as the production data ROM. However, a ROM (production program ROM) that can only be written in a manufacturing factory may be used, which makes it difficult to forge the ROM. Therefore, it is possible to prevent the illegality of replacing with an illegal ROM.
