Description

  The present invention relates to a gaming machine such as a slot machine, and more particularly to a gaming machine that can prevent illegal acts such as ROM replacement and ROM tampering.

  A gaming machine such as a slot machine or a pachinko machine has a built-in microcomputer (CPU), and controls lottery, winning, payout, and production by a program. This type of gaming machine receives an operation from the player, performs an internal lottery and a prize determination according to the lottery result, and controls a game medium payout control according to the prize, and receives a command from the main board. And a sub-board for notifying the result of the internal lottery and performing various effects.

  In many games, the display itself such as a liquid crystal display device, a speaker, or a display lamp is used to notify a player of a prize or the like, or a specific small role is played between certain games during a so-called assist time (AT). Tell the user with some action. (Assist Time (AT): Even if a specific small role is established, the player will not be refunded unless the symbols on the reels are aligned. Alternatively, the assist time is drawn at any other opportunity, and if this is won, the player is instructed to perform an operation for establishing a specific small role for a certain game with some action)

  As with the AT, there is a gaming machine in which the weight of the winning rate is controlled by software on the sub-board side. The sub-board side has a function to adjust the protruding balls. Specifically, as described above, an instruction for obtaining a ball is displayed on the liquid crystal display device so that the player can easily obtain the ball if the player operates according to the instruction. This instruction is not always issued, but is issued in a specific case.

  In this way, the main board and the sub board realize the lottery, winning, payout, and production control by the program. The program for each board performs important control related to the game.

  There are some who try to get the ball out illegally by using the AT function. A ROM whose program has been tampered with in an advantageous manner is illegally attached to the main board or sub board.

  By the way, game machines such as slot machines and pachinko machines are regulated by law, and therefore the program for each board needs to be verified and approved in advance by the relevant organizations, and can be altered without permission. Not. The program mounted on each board, specifically the contents of the ROM, is determined at the time of application to the related organizations, and the contents of the ROM of the same type of gaming machine are always required to be the same.

  However, the ROM may be exchanged using illegal means and the contents of the program may be changed. The damage caused by such fraudulent acts is squeezing up the hall management and becoming a social problem. A ROM (particularly a sub-board) used in a gaming machine is a general-purpose semiconductor memory having a package conforming to a semiconductor standard (JEDEC, EIAJ, etc.). This is generally readily available and is simply a socket implementation, so it may be replaced with an illegal ROM. In addition, there are few preventive measures against exchanges by third parties.

  An object of the present invention is to solve such a problem, and an object of the present invention is to provide a gaming machine capable of preventing illegal acts such as ROM replacement and ROM tampering.

A gaming machine according to the present invention is a gaming machine comprising a substrate including at least a semiconductor memory and a connector for detachably mounting the semiconductor memory.
The semiconductor memory is a memory module housed in a rectangular parallelepiped or plate-shaped package, one of the side surfaces of which is a connection surface, and a connector is provided on the connection surface.
In order for the memory module to be mounted in parallel to the substrate and to be fitted to the connector of the substrate, the insertion / extraction direction of the connector of the substrate is directed substantially parallel to the substrate,
An opening is provided in a part of the memory module, and a board opening is provided at the position of the board corresponding to the opening when the connector of the memory module is fitted to the connector of the board.
When the memory module is mounted on the substrate, the opening of the memory module and the opening of the substrate are penetrated and locked by a locking member.

  A plurality of memory modules may be stacked and mounted. In this case, if the first connector is provided on the second connector provided on the substrate so as to be shifted by a predetermined distance in the insertion / extraction direction, the label of the lower second memory module can be exposed. It is preferable that the shift between the first connector and the second connector corresponds to the size of the display label on the memory module.

In the case where a plurality of memory modules are mounted in a stacked manner, when a plurality of openings are provided in each memory module, the displacement of the position of any one of the openings is made to correspond to the displacement of the first connector and the second connector.
The opening of the memory module is provided around the semiconductor memory and the package where there is no connection line.

  When mounting a plurality of memory modules in a stacked manner, when a plurality of openings are provided in each memory module, the intervals between the plurality of openings in the first memory module and the intervals between the plurality of openings in the second memory module are the same. In addition, if the distance from the connection surface to the opening in the first memory module is the same as the distance from the connection surface to the opening in the second memory module, each memory module is compatible. be able to.

  As the locking member, a caulking member including a hook shape and an eyelet shape can be used. A binding member (binder) or the like that can be tightened but cannot be loosened and can only be broken and cut is used.

  According to the present invention, since the semiconductor memory can be locked and sealed to the substrate, unauthorized parts replacement can be made difficult. Even if it is exchanged, it is possible to leave a trace.
