Description

  The present invention relates to a gaming machine in which a harness-side connector connected to a control board housed in a board case is covered with a connector cover.

  In recent years, game machines such as general pachinko machines and pachislot machines (slot machines) use a large number of electronic components and use a program control system to control and manage the game state of the game machine. Electronic parts such as a microprocessor unit (MPU), IC and LSI are mounted on a circuit board and used.

  For example, in the case of a pachislot machine, the program control method determines the winning (bonus) state, issues a medal payout command, monitors the player's start and stop operation states, and responds accordingly. It is responsible for centralized management operations of pachislot machines, such as controlling the rotation of the body reels and issuing commands to display the gaming status. The control program for that purpose is stored in a read-only memory (ROM), and it contributes to the provision of a flexible and economical pachislot machine, such as adding a new function by replacing this ROM.

By the way, in gaming machines with gambling characteristics such as pachinko and pachislot, illegal acts called “goto acts” have not been followed for a long time, but with the computerization of gaming machines, for example, a regular control program has been added. Such as replacing the read-only memory (ROM) with an illegal program ROM, accessing the electronic components and printed wiring on the circuit board using a wire, etc., and causing the electronic circuit to malfunction due to grounding or shorting, etc. Problems with cheating have also arisen.
Therefore, the circuit board of the gaming machine is housed in a board case made of a transparent hard resin, and measures for preventing these unauthorized access actions are taken (for example, see Patent Document 1).

Absent. For this reason, for example, a wire or the like is inserted from the gap, and the board circuit or electronic component is touched to change the operation of the board circuit to obtain a prize.

  In addition to this, in the past, a person involved in an amusement facility or the like has performed an illegal act of removing a legitimate harness from a board-side connector and replacing a board case containing a legitimate circuit board with a board case containing an illegal circuit board. In some cases, a data signal input device called a driving machine is connected to the board-side connector from which the regular harness is removed, and the normal mode is changed to a mode such as a replay time.

  In response to this, in recent years, an engagement claw for prohibiting the harness side connector from being pulled out from the board side connector by engaging the board side connector with respect to the harness side connector is provided. An operation part for releasing the engagement of the engagement claw with the connector is provided, a connector cover is attached to the harness side connector, the gap between the connector insertion opening and the connector of the board housing case is closed, and the harness side connector A slot machine that prevents the harness side connector from being pulled out from the board side connector by preventing the operation unit from being operated has been put into practical use. Here, the connector cover has a flat portion in which a through-hole through which the harness is inserted and four walls are opened, and one surface is opened, and the fitting portion of the harness-side connector protrudes from the opening.
