Description

  The present invention relates to a board case structure of a gaming machine suitable for use in a slot machine or a pachinko machine.

  A control board for controlling the operation of the gaming machine is provided in a housing of a gaming machine such as a slot machine or a pachinko machine. For example, in a slot machine, a main control board on which electronic components such as a CPU, a ROM, and a RAM are mounted is mounted in the casing, and the main control board is used for paying out award balls and medals, opening and closing of electric components, and reels. Rotation, the probability of symbol combinations, etc. are controlled. In addition, a sub-control board on which electronic components that receive signals from the main control board are mounted is mounted in a front panel casing that is attached to the main body casing so as to be openable and closable. It controls presentation display devices such as lamps. The main control board and the sub control board are each housed in a board case. The substrate case includes a case main body and a case cover that covers the case main body. Then, after the board case containing the control board on which the regular electronic components are mounted is attached to the mounting base of the gaming machine with a fastening screw, the fastening screw is further “clamped”. In addition, in order to prevent unauthorized actions such as CPU, ROM, RAM and other electronic components on the control board being replaced with modified electronic components, and to prevent the case cover from being illegally opened, the case cover is also illegally opened. If it is, it is sealed with a special screw or a sealing seal so that the trace remains (for example, see Patent Document 1).
