Description

  The present invention relates to a control device for a gaming machine in which a control board of a gaming machine is housed in a container, and more specifically, an unauthorized operation is performed on the internal control board from the outside of the container. The present invention relates to a technique that can reliably prevent this and can greatly improve the assembling property of the container.

  Conventionally, control relating to the appearance of balls in a gaming machine such as a ball ball game machine or a slot machine is performed by a control board called a main control board. In addition, in recent gaming machines, in addition to the main control board, there may be provided a control board called a sub-control board that substantially performs control related to the outgoing ball.

  And in such a gaming machine, it differs from the original game by falsifying the program, giving an illegal signal from the outside, etc. to the control program or input / output signal etc. of the main control board or sub control board An illegal act of playing an inappropriate game is a problem.

FIG. 9 is a perspective view showing an example of a main control board 23 used in a conventional control device for a gaming machine.
As shown in FIG. 9, various electronic components are mounted on the main control board 23, and a plurality of connectors 40 for electrically connecting the main control board 23 and an external device (not shown). The connector 50 is attached.

  Here, if the main control board 23 is exposed to the outside as it is, there is a possibility that electronic components such as a control ROM may be replaced with a non-genuine one. Moreover, since various electronic components, each connector 40, and each connector 50 are mutually connected by the wiring pattern printed on the main control board 23, the connection of an illegal component with respect to a wiring pattern, a short circuit of wiring, etc. It is also possible to perform. That is, it is conceivable that an unauthorized operation is performed on the main control board 23. If such an action cannot be effectively prevented, a serious damage will occur at a game store or the like.

  Therefore, a control board such as the main control board 23 is accommodated inside a container made of transparent resin, and measures are taken to prohibit unauthorized opening of the container so that the container cannot be easily opened. A technique for preventing an unauthorized operation on the main control board 23 and the like is known.

FIG. 10 is a plan view showing the control device 30 of such a conventional gaming machine.
As shown in FIG. 10, the control device 30 houses a main control board 23 (see FIG. 9) on which a plurality of connectors 40 and connectors 50 are mounted inside a board cover 33 (housing body). .

  Here, one end side of the substrate cover 33 is rotatably connected by a hinge 35, and the other end side is sealed by a lock member 39. Therefore, the controller 30 shown in FIG. 10 is prohibited from unauthorized opening of the substrate cover 33, and as a result, unauthorized replacement of electronic components mounted on the main control substrate 23 can be prevented.

  However, by prohibiting unauthorized opening of the board cover 33, it is possible to prevent unauthorized acts such as tampering with the program by directly exchanging the electronic components of the main control board 23, but the wiring pattern printed on the main control board 23 can be prevented. On the other hand, it is not possible to prevent illegal acts such as giving an illegal signal from the outside.

  That is, with respect to the peripheral portions of the connector 40 and the connector 50 mounted on the main control board 23, the board 40 and the connector 50 are electrically connected to the main control board 23 and an external device (not shown). The cover 33 is formed with an opening 34 into which the connector 40 or the connector 50 can be inserted.

  Therefore, a gap is generated between the opening 34 and the side surface of the connector 40, or between the opening 34 and the side surface of the connector 50, and the wiring pattern that connects the connector 40 and the connector 50 to the electronic component is partially formed. Exposed. As a result, unauthorized parts can be connected to the exposed portion, wiring can be short-circuited, and the like, and there is a possibility that an inappropriate game will be executed.

  Thus, even if the main control board 23 is accommodated in the board cover 33, the peripheral portions of the connector 40 and the connector 50 mounted on the main control board 23 remain as problems. Therefore, there is a strong demand for a technique that can reliably prevent an unauthorized operation from being performed on the internal main control board 23 from the outside of the board cover 33 including the peripheral portions of the connector 40 and the connector 50.

Therefore, recently, a technique using a substrate cover 33 (container) in which a gap between the opening 34 and the side surface of the connector 40 or a gap between the opening 34 and the side surface of the connector 50 is minimized. That is, the container using this technology has a structure that allows various control boards such as the main control board 23 to be seen through from the outside. The container is provided with a step portion that comes into contact with the control board. An opening for fitting the connector is provided in the stepped portion. Then, the periphery of the opening is brought close to the connector so that the printed wiring pattern is not exposed, and the printed wiring pattern in the peripheral portion of the connector is covered by the stepped portion (for example, Patent Document 1). reference).
Japanese Patent No. 2905773

According to the technique described in Patent Literature 1 above, the internal control board can be easily seen through from the outside of the container, so that the electronic component mounted on the control board is illegally replaced or the like. Even so, the fact can be easily discovered.
Moreover, since the periphery of the opening of the container is close to the connector, it is possible to prevent an unauthorized operation from being performed on the wiring pattern of the control board from the opening.

However, in the technique described in the above-mentioned Patent Document 1, since the opening portion into which the connector is fitted is provided in the step portion of the housing body, a separate housing body is required for each control board having a different connector arrangement. turn into. Therefore, there are problems with the productivity and economics of the container.
In addition, the closer the opening of the container is to the connector, the more difficult it is to insert the connector into the opening, so it becomes difficult to cover the container from the upper side of the control board. There is a problem that gets worse.

  On the other hand, in consideration of the assembly of the container, the container (substrate cover 33) is rotated by using the hinge 35 as shown in FIG. 10 instead of covering the container from above the control board. A technique is also known in which the control board (main control board 23) can be easily accommodated inside.

  However, in the case of such a container, a gap corresponding to the radius of rotation is required between the opening and the connector, so that there is a limit to the degree of proximity between the periphery of the opening and the connector. For this reason, the technique described in Patent Document 1 cannot be applied to a container that is opened and closed using such a hinge, and there is a problem in that the assemblability of the container cannot be improved. .

  Therefore, the problem to be solved by the present invention is to reliably prevent an unauthorized operation from being performed on the internal control board from the outside of the container including the peripheral portion of the connector, It is an object of the present invention to provide a control device for a gaming machine that can be applied to a container that is opened and closed using a hinge so that the assemblability of the container can be greatly improved.

The present invention solves the above-described problems by the following means.
The invention of claim 1 is for electrically connecting a control board for controlling a gaming machine, the control board and an external device, a connector mounted on the control board, and the control board A control device for a gaming machine comprising a housing for housing the connector therein, wherein the connector includes a protective body surrounding a side surface of the connector, and the housing includes an opening into which the connector can be inserted; The connector is inserted into the opening of the container, and the container in a state in which the control board is housed in the container. The shielding piece is inserted between a side surface of the connector and the protective body.

  According to a second aspect of the present invention, in the gaming machine control device according to the first aspect, the protective body includes an upper surface opening into which the connector can be inserted, a side wall that can surround a side surface of the connector, and the connector. And a lower surface opening for mounting on the control board.

  According to a third aspect of the present invention, in the gaming machine control device according to the first or second aspect, the protective body is fixed by sandwiching the protective body between a lower surface of the connector and an upper surface of the control board. It has the fixed piece for performing.

  According to a fourth aspect of the present invention, in the gaming machine control device according to any one of the first to third aspects, the container has an opening into which a plurality of the connectors can be inserted simultaneously. The protective body has an upper surface opening portion into which a plurality of the connectors can be simultaneously inserted.

  According to a fifth aspect of the present invention, in the game machine control device according to any one of the first to fourth aspects, the container has an auxiliary shielding piece surrounding the shielding piece, The protective body is inserted between the shielding piece and the auxiliary shielding piece of the container.

  A sixth aspect of the present invention is the game machine control device according to any one of the first to fifth aspects, wherein the container or the protective body is made of a transparent resin.

  A seventh aspect of the present invention is the game machine control device according to any one of the first to sixth aspects, further comprising a support body on which the control board is placed, wherein the housing body is the support body. It is connected to the one end side of this so that rotation is possible.

  The invention of claim 8 is the game machine control device according to any one of claims 1 to 7, wherein the game machine is a ball game machine having a symbol variation display device, and the control The substrate controls the variation of the symbol displayed on the symbol variation display device.

  A ninth aspect of the present invention is the gaming machine control device according to any one of the first to seventh aspects, wherein the gaming machine is a slot machine having a reel displaying a symbol, and the control board. Controls the rotation of the reel.

  In each of the above inventions, a protective body surrounding the side surface of the connector is provided. And the shielding piece of a container is inserted between the side surface of a connector, and the side wall of a protection body. That is, the periphery of the side surface of the connector is surrounded by a shielding piece from the housing body side to the control board side, and the periphery of the shielding piece is surrounded by the side wall of the protective body from the control board side to the housing body side. Therefore, when considered in a cross section, the side surface of the upward connector, the shielding piece of the downward housing, and the side wall of the upward protective body are alternately present.

  Therefore, even if there is a gap between the side surface of the connector and the shielding piece of the container, or between the shielding piece of the container and the side wall of the protective body, it is arranged in a staggered manner from the outside of the container. The control board inside the container cannot be reached without passing through the side of the connector, the shielding piece of the container, and the side wall of the protective body. The connection of various parts is prevented.

  In addition, since the opening of the container can be enlarged to some extent with respect to the connector inserted into the opening, the container is rotatably connected to the support on which the control board is placed using a hinge or the like. Even if it is a container, a connector does not become a hindrance at the time of an assembly of a container, and a control board can be easily accommodated in the inside of a container.

  Here, the protection body has, for example, an upper surface opening part into which the connector can be inserted, a side wall capable of surrounding the side surface of the connector, and a lower surface opening part for mounting the connector on the control board. Such a protective body must be fixed so as not to be detached from the control board. At this time, a fixed piece is provided on the protective body, and the fixed piece is attached to the lower surface of the connector and the upper surface of the control board. So that the protective body can be fixed at the same time that the connector is mounted on the control board.

  In addition, if a plurality of connectors can be simultaneously inserted into the opening of the container and a plurality of connectors can be simultaneously inserted into the upper surface opening of the protective body, the control board having a different connector arrangement can be accommodated. However, it is only necessary to prepare separate protective bodies according to the arrangement of the connectors. Therefore, if such a protective body is used, a container can be made common to various control boards having different connector arrangements.

  Further, if the container is provided with an auxiliary shielding piece surrounding the shielding piece and the side wall of the protective body is inserted between the shielding piece of the containing body and the auxiliary shielding piece, the side wall of the upwardly facing protective body The surrounding area is also surrounded by a downward-facing auxiliary shielding piece. Then, since the auxiliary shielding pieces are also arranged in a zigzag shape, it becomes possible to more reliably prevent connection of unauthorized parts.

  Furthermore, if the container or the protective body is made of a transparent resin, it is possible to easily find unauthorized replacement of electronic components mounted on the control board inside the container or around the protective body. Become. That is, since the internal control board can be easily seen through from the outside of the container without opening the container, it becomes obvious at a glance whether the electronic component mounted on the control board is a genuine product. Here, in order to detect fraud, it is preferable to form both the container and the protective body with a transparent resin.

  Note that the gaming machine using such a control device may be a ball game machine having a symbol variation display device or a slot machine having a reel displaying symbols, and in the case of a ball game machine The control board controls the fluctuation of the symbol displayed on the symbol fluctuation display device, and the control board in the case of the slot machine controls the rotation of the reel. Here, it is natural that the control board includes both the main control board and the sub control board, whether it is a ball game machine or a slot machine.

  According to the gaming machine control device of the present invention, the protective body surrounding the side surface of the connector is provided, and the shielding piece of the container is inserted between the side surface of the connector and the protective body. Even if there is a gap between the shielding piece and between the shielding piece and the protective body of the container, it is difficult to connect unauthorized parts to the internal control board from the outside of the container. . Therefore, the control device for a gaming machine of the present invention can reliably prevent an unauthorized operation on the control board inside the container.

  In addition, even in the case of a container that is rotated using a hinge or the like, a gap is provided between the side surface of the connector and the shielding piece of the container, and between the shielding piece of the container and the protective body. Thus, the control board can be easily accommodated inside the container. Therefore, the assemblability of the container can be greatly improved.

Further, the protective body 70 has a fixing piece 74 for sandwiching and fixing the protective body 70 between the lower surface of each connector 50 and the upper surface of the main control board 23.

  Then, instead of directly attaching each connector 50 to the main control board 23, each connector 50 is simultaneously inserted into the upper surface opening 71 of one protective body 70 shown in FIG. A fixing piece 74 is sandwiched between the lower surface and the upper surface of the main control board 23, and each connector 50 is attached to the main control board 23 through the lower surface opening 73. Then, as shown in FIG. 5, the periphery of each connector 50 becomes the main control board 23 surrounded by the protective body 70 shown in FIG. 6B.

FIG. 7 is a partial cross-sectional view showing the control device 30 of the gaming machine according to the first embodiment, and shows a state where the main control board 23 is housed inside the board cover 33.
In FIG. 7, the connector 40 is inserted into the protective body 60 (see FIG. 6A), but this relationship is the same between the connector 50 and the protective body 70 (see FIG. 6B). It is. That is, even if the connector 50 is inserted into the protective body 70, it becomes as shown in FIG. 7 (the code in this case is shown in parentheses).

  As shown in FIG. 7, when the connector 40 is inserted into the upper surface opening 61 of the protective body 60 and attached to the main control board 23, the fixing piece 64 of the protective body 60 is attached to the lower surface of the connector 40 and the upper surface of the main control board 23. It is sandwiched between. Therefore, the protective body 60 is fixed. Further, the side surface 41 of the connector 40 is surrounded by the side wall 62 of the protective body 60.

  As shown in FIG. 7, in a state where the main control board 23 on which the connector 40 is mounted via the protective body 60 is housed in the board cover 33, the connector 40 is inserted into the opening 34 of the board cover 33. The upper surface 42 of the connector 40 is exposed to the outside of the substrate cover 33. Therefore, if a harness (wiring bundle) (not shown) is connected to the exposed upper surface 42 of the connector 40, the main control board 23 and the external device are electrically connected.

  Here, the board cover 33 has a shielding piece 81 formed at the lip of the opening 34 into which the connector 40 is inserted. The shielding piece 81 is inserted between the side surface 41 of the connector 40 and the side wall 62 of the protective body 60 in a state where the main control board 23 is accommodated inside the board cover 33. Then, the periphery of the side surface 41 of the connector 40 is surrounded by the shielding piece 81 of the board cover 33, and the periphery of the shielding piece 81 is surrounded by the side wall 62 of the protective body 60.

  Therefore, as shown in FIG. 7, the side surface 41 of the upward connector 40, the shielding piece 81 of the downward substrate cover 33, and the side wall 62 of the upward protective body 60 are provided around the opening 34 of the substrate cover 33. It will exist alternately. And the clearance gap between the side surface 41 of the connector 40 and the shielding piece 81 of the board | substrate cover 33, and the clearance gap between this shielding piece 81 and the side wall 62 of the protection body 60 are narrow space | interval of 2 mm or less, respectively.

  Therefore, even if the control device 30 of the gaming machine according to the first embodiment inserts a wire or the like from the opening 34 of the board cover 33, the side surface 41 of the connector 40 arranged in a staggered manner, the shielding of the board cover 33. The main control board 23 accommodated inside the board cover 33 cannot be reached unless it passes through between the piece 81 and the side wall 62 of the protection body 60. As a result, it is possible to prevent a short circuit of the wiring with respect to the wiring pattern printed on the main control board 23, an unauthorized connection of components, and the like.

  As described above, in the gaming machine control device 30 of the first embodiment, the substrate cover 33 and the substrate base 31 (see FIG. 3) are rotatably connected. As described above, there is a gap between the shielding piece 81 of the substrate cover 33 and the side surface 41 of the connector 40, and this gap corresponds to the rotation radius of the substrate cover 33.
