Description

  The present invention relates to a sealing structure for a board case of a gaming machine for housing a circuit board.

  In gaming machines such as pachinko machines and slot machines, circuit boards mounted with electronic components such as ROM chips in which winning probabilities are written are used, but this circuit board has an opening in the case body and the case body. It is accommodated in a substrate case made up of a cover. The substrate case is provided with a sealing structure that makes it impossible to open the lid in order to prevent an unreasonable advantage from replacing the internal ROM chip.

  As a substrate case having a conventional sealing structure, for example, there is one described in Patent Document 1. In this state, the lid is assembled to the case body, and the internal space of the case side tube portion and the cover side tube portion is connected to each other. A spring pin that is inserted across the cover-side cylinder part is fitted to at least one of the case-side cylinder part and the cover-side cylinder part, and the case main body and the lid body are fixed.

  However, in the above, since the attachment piece connecting the lid side cylinder portion and the lid body can be opened simply by cutting with a nipper or the like, no trace of opening is left on the case body side. Therefore, for example, if an intact case body taken out from a gaming machine that is no longer used after destroying and opening the case body and replacing it with an unauthorized ROM, it is determined that the board case has been unlawfully opened. There was a problem that it was not connected.

Patent Document 2 describes a substrate case locking structure that seals a lid body to a case body with a first sealing member and a second sealing member. In this case, it can be opened simply by cutting the bridge of the case body and the bridge of the lid, but it is not always necessary to cut both bridges, and it can be opened only by cutting one of the bridges. Therefore, there was a problem similar to that described above. Furthermore, when both bridges are cut, the support part of the first sealing member and the support part of the second sealing member are separated from the substrate case while containing the sealing member. For example, the sealing member itself is destroyed. Then, after opening and replacing with an illegal ROM, if the intact sealing member in the support part separated and discarded from the substrate case is used, it is impossible to determine that the substrate case is illegally opened. there were.
