Description

  The present invention relates to a gaming machine equipped with a control unit that covers a base back cover with a base protective cover and accommodates a control base for controlling game contents inside the base box.

  In gaming machines such as pachinko machines and slot machines, game contents are controlled by signals from a control circuit configured on a control board. For this reason, tampering with the control circuit components on the control board, for example, a chip such as a CPU or a ROM, which is replaced with a modified CPU or a modified ROM, is often a problem.

Basically, in order to prevent unauthorized modification, conventionally, in a pachinko machine, for example, as shown in FIG. 12, in a base box composed of a base back cover 16 and a base protective cover 17, the control base 15 is connected to the base back. It is fixed to the cover 16 side and covered with a base protection cover 17. And it caulked with the caulking member etc. so that the board | substrate protective cover 17 cannot be opened easily. A sealing seal 18 is attached to the boundary between the base protection cover 17 and the base back cover 16 to prevent opening. This is because if the base protection cover 17 is opened, the sealing seal 18 is broken, so that the tampering of the control base 15 can be easily detected. The base box is entirely formed of a transparent resin. This is because the arrangement state of the chips of the control board 15 can be seen without opening the board protection cover 17 so that it can be detected immediately if the control board 15 is illegally modified.

  As described above, despite various measures for preventing fraud, unauthorized modification such as replacement of the built-in ROM is still performed. In particular, there is a malicious modification that removes regular roms on the spot and replaces them with remodeled roms, so-called back roms, while keeping an eye on pachinko parlors during business hours. In this case, since the unauthorized modification is performed during the business hours of the pachinko parlor, it is necessary to perform the unauthorized modification in a short time so as not to be noticed by the store clerk. However, in the conventional gaming machine, the control base is mounted on the base back cover side, and the surface of the control base is exposed as long as the base protection cover is removed. Therefore, it is possible to quickly replace the regular rom with the back rom. It was.

  Further, unauthorized modification may be performed by inserting an instrument through a slight gap between the base back cover and the base protective cover.
