Description

  The present invention relates to a control board for controlling a game, and a control board unit in a gaming machine including a board case in which the control board is accommodated.

  Conventionally, in gaming machines such as slot machines and pachinko machines, electronic components such as ROM for controlling games, board-side connectors to which external connectors are connected, and printed wiring for electrically connecting electronic components and board-side connectors are provided. An electronic control system is used to control the gaming operations of various gaming machines by mounting the control board provided in the gaming machine and connecting the external connectors on the various gaming machines side controlled by the control board to the board side connectors. Yes.

In addition, the control board is a board-side connector so that unauthorized modification such as replacement of the ROM of the control board or unauthorized manipulation such as piano wire or the like entering the game machine to illegally control the control board cannot be performed. In such a form that only the surface is exposed, it is accommodated in a substrate case formed of a transparent synthetic resin material (see, for example, Patent Document 1).
JP 2001-178940 A

  However, in the gaming machine as described above, since the board-side connector is exposed from the opening provided in the board case, the board-side connector and the opening are caused by a molding error of the board case, variation in the mounting position of the board-side connector, etc. A gap is created between the edge of the control board and the control board is illegally controlled by inserting a fraudulent tool into the board case and shorting the printed wiring around the board-side connector. There is a risk of being.

  An object of the present invention is to provide a control board unit in a gaming machine that can reliably prevent an illegal act such as illegally controlling a control board using a fraudulent tool in view of conventional problems. And

According to the present invention, the above problem is solved as follows.
(1) An electronic component for controlling a game, a connector to which an external connector is connected, and a control board provided with a printed wiring are housed in a board case composed of a case body and a case lid for closing the case body, In a control board unit in a gaming machine in which an opening for exposing the connector is provided in the case lid, the printed wiring of the peripheral part of the connector is formed on the control board separately from the connector. A shielding plate for shielding is provided.

(2) In the above item (1), a flange portion that protrudes toward the shielding plate and whose end portion can contact the shielding plate is provided around the opening in the case lid.

(3) In the above item (2), a protrusion that can surround the outer peripheral edge of the shielding plate is provided at the end of the flange.

(4) In the above item (2) or (3), the shielding plate is provided with a concave groove into which the end of the flange portion can be recessed.

(5) In the above item (2) or (4), the shielding plate is provided with a protrusion that protrudes toward the case lid and can surround the outer periphery of the flange portion of the case lid.

(6) In any one of the above items (1) to (5), the shielding plate has a size capable of continuously shielding the printed wiring around the plurality of connectors provided on the control board.

(7) In any one of the above items (1) to (6), the control board is fixed to the case lid.

According to the present invention, the following effects can be achieved.
(A) According to the invention described in claim 1, since the printed wiring in the peripheral portion of the connector is shielded by the shielding plate, it is illegal to create a piano wire or the like in the gap between the lip of the opening and the outer surface of the connector. Even if the tool is inserted, it is possible to reliably prevent an illegal act such as a short circuit of the printed wiring.

(B) According to the invention described in claim 2, by providing the flange portion around the opening portion in the case lid body, the rigidity around the opening portion in the case lid body is increased to reduce the bending, and the end of the flange portion is reduced. The portion can be reliably brought into contact with the shielding plate. Thereby, the clearance gap between a case cover body and a shielding board can be shielded reliably, and the illegal act of making an unauthorized tool penetrate | invade in a board | substrate case can be prevented reliably.

(C) According to the invention described in claim 3, the protruding portion of the flange portion surrounds the outer peripheral edge of the shielding plate, so that the gap between the case lid and the shielding plate is reliably shielded. It is possible to more reliably prevent fraudulent acts such as intruding into the substrate case.

(D) According to the invention described in claim 4, the end of the flange portion is recessed into the concave groove of the shielding plate, so that the gap between the case lid and the shielding plate is reliably shielded. It is possible to more reliably prevent fraudulent acts such as causing the tool to enter the substrate case.

(E) According to the invention described in claim 5, the protrusions of the shielding plate surround the outer periphery of the flange portion of the case lid so that the gap between the case lid and the shielding plate is reliably shielded. It is possible to more reliably prevent fraudulent acts such as allowing unauthorized tools to enter the substrate case.

(F) According to the invention described in claim 6, since the printed wiring in the peripheral portion of the plurality of connectors can be continuously shielded by a single shielding plate, the printed wiring can be shielded in a wide range. The action can be more reliably prevented, and the assembling work of the shielding plate can be simplified.

(G) According to the invention described in claim 7, by fixing the control board to the board case, the connector can be easily exposed from the opening, and the assembling work can be improved.
