Description

  The present invention relates to a board case for a gaming machine, and more particularly to a board case for a gaming machine that accommodates circuit boards that are provided in the gaming machine and arranged in two stages.

  In game machines such as a throttle machine and a pachinko machine, a ROM in which game contents are written is mounted on a circuit board. As described in Patent Document 1, such a circuit board is sandwiched between a case base and a case lid attached to a gaming machine in order to prevent unauthorized exchange of ROM. The substrate case is housed inside so that the case base and the case lid cannot be separated by the sealing means.

  Various circuit boards are mounted in the gaming machine, but since the space part in the gaming machine is a limited area, it is necessary to use this space part effectively. Therefore, a board case is used in which another case lid that can accommodate another circuit board is integrally attached to the front side of the case lid.

JP 2004-65791 A

  In general, a substrate case that accommodates a circuit board is formed of a transparent or translucent material to facilitate confirmation of electronic components attached to the circuit board, but the circuit board is accommodated in two stages. In the case of the board, the electronic components attached to the upper circuit board can be visually confirmed by visually checking the inside of the board case from the front side, but the upper circuit board interferes with the lower circuit board. Thus, the electronic components attached to the lower circuit board cannot be visually confirmed.

  Therefore, when the circuit board accommodated in the upper case cover is removed, the electronic components attached to the lower circuit board can be visually confirmed. However, the upper case cover is often attached to the lower case cover by sealing means, and the upper case cover cannot be removed without breaking the sealing means, which is troublesome. Moreover, if the sealing means is broken, a new case lid or the like is required, which causes a problem that costs increase. For this reason, in the lower case, only circuit boards with electronic components that do not require visual confirmation can be accommodated, and the expansion of the freedom of arrangement of circuit boards in gaming machines is currently limited. is there.

  The present invention can easily check the electronic components attached to the circuit board accommodated in the lower case, and can increase the freedom of arrangement of the circuit board in the gaming machine. Therefore, it is an object of the present invention to provide a board case for a gaming machine that meets such demands.

  In order to solve such problems, the present invention provides a case base that is attached to a gaming machine (for example, the slot machine 1 in the embodiment), and a first case lid that is attached to the case base and formed of a transparent material. And a second case lid portion that is attached to the first case lid portion, and controls the operation of the gaming machine inside the first case formed by attaching the first case lid portion to the case base portion. One circuit board (for example, the image processing substrate 31 in the embodiment) is accommodated, and the second circuit board (for example, the embodiment) is formed inside a second case formed by attaching the second case lid to the first case lid. In which the second case lid is detachably attached to the first case lid, and the second circuit board is attached to the second circuit board. Second electronic case So as to face the inner surface of the top plate parts are disposed inside the second casing lid, characterized in that attached to the second casing lid.

  According to the present invention, the second case lid is detachably attached to the first case lid formed of a transparent material, and the second circuit board has the electronic component attached thereto attached to the second case lid. When the second case lid is removed from the first case lid by being disposed on the inner side of the second case lid so as to face the inner surface of the top plate portion and attached to the second case lid, The circuit board is also separated from the first case cover part together with the second case cover part, and the top plate part of the first case cover part is exposed. For this reason, the electronic component attached to the circuit board accommodated in the first case can be visually confirmed through the top plate portion. Moreover, since the second circuit board is separated from the first case lid simply by removing the second case lid from the first case lid, there is no need to remove the second circuit board from the second case lid. For this reason, visual confirmation of the electronic component of the circuit board accommodated in the 1st case can be performed easily. Therefore, it is possible to positively accommodate a circuit board on which an electronic component that requires visual confirmation is attached in the first case, and to increase the freedom of arrangement of the circuit board in the gaming machine.

  Further, the second case lid portion of the present invention is characterized in that the second case lid portion can be rotated around a rotation fulcrum provided on one end side of the first case lid portion.

  According to the present invention, the second case lid can be rotated about the rotation fulcrum provided on one end side of the first case lid so that the second case lid is the first case. The top plate portion of the first case lid portion can be exposed only by rotating with respect to the lid portion, and the electronic components of the circuit board accommodated in the first case can be visually confirmed. For this reason, visual confirmation of the electronic component of the circuit board accommodated in the 1st case can be performed more easily.

  The second circuit board of the present invention is attached to the second case lid by a sealing means.

  According to this invention, by attaching the second circuit board to the second case lid by the sealing means, it is impossible to touch the electronic component attached to the second circuit board unless the sealing means is broken. For this reason, fraudulent acts on the electronic components of the second circuit board can be prevented with high deterrence.

  According to the present invention, the second case lid is detachably attached to the first case lid formed of a transparent material, and the second circuit board is attached to the electronic component attached to the second case lid. An electronic component mounted on a circuit board housed in a lower-side board case by being placed inside the second case lid so as to face the inner surface of the top plate of the board and attached to the second case lid Thus, it is possible to provide a board case for a gaming machine in which the visual confirmation of the board can be easily performed and the freedom of arrangement of circuit boards in the gaming machine can be expanded.
