Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine having a board box for accommodating a control circuit board.

[0002]

2. Description of the Related Art In a conventional gaming machine, for example, a pachinko gaming machine, a control circuit such as an accessory control device for controlling a game of the gaming machine or a ball ejection control device for controlling a ball ejection device is provided on the back side of the gaming machine. Is provided in the box.

[0003] The board box is a resin or metal box containing a control circuit board on which various electronic components such as ICs (integrated circuits) and resistors are mounted to prevent short-circuits and dust. Is protected from intrusion,
It can be attached to the back side of a back mechanism base board or a game board provided on the back side of the front frame of the gaming machine.

For example, in the accessory control device, a CPU, a ROM (memory), a RAM (memory), and the like are provided in a control circuit, and game control is performed according to a program stored in the ROM, and a big hit or the like is performed. Is also controlled here.

[0005] The board box is generally a box body in which an upper cover member and a bottom cover member are overlapped, and a connector portion for electrically connecting to various other devices is provided so as to be exposed from the box. By connecting various wirings via a connector section, control relating to each of them can be performed.

Since the board box houses control circuit boards related to game control, it is liable to be mischievous or fraudulent. Therefore, in the board box,
Once opened, a seal is attached to the joint between the top lid member and the bottom lid member, or the surface of the substrate box is formed of clear resin and stored, so that it can be seen that it has been opened. The state of the control circuit board was made visible from the outside.

When storing the control circuit board in the board box, first, the control circuit board is locked to the bottom cover member of the board box by a fixing member such as a screw. When the member is provided, the protection member is also locked together, and thereafter the upper cover member and the bottom cover member are engaged to close the substrate box, and sealing (sealing, caulking) and the like are performed.

As described above, by covering the control circuit board with the upper lid member and the bottom lid member with the connector portion exposed, various wirings can be detached from the connector portion without opening the board box. Therefore, a configuration having both workability and safety is realized.

[0009]

Recently, one of the frauds that have occurred in game arcades is the mounting of a fraudulent board called a "hanging board" on a game machine. The "hanging board" is a board for inputting an incorrect signal to the control circuit board, and the jackpot is generated by the incorrect signal.

[0010] The injustice caused by the "hanging board" can be realized without any modification to the electronic components such as the ROM of the control circuit board covered by the board box. In this case, the fraudulent player attaches the “hanging board” to the gaming machine during the operation of the game store, but as a trick, once pulls out the wiring code from the connector portion of the control circuit board, and attaches the “hanging board” to the wiring code. In this connection, the wiring cord is inserted into the connector again. The installation work time is short (about 30 seconds), and the "hanging substrate" to be mounted is also miniaturized, so that it is not easy to find out.

[0011] Measures for preventing such fraud are as follows.
It is not applied in the conventional board box. That is,
Because the wiring cord can be easily attached and detached from the connector,
The mounting of the "hanging board" is easy, and the connector part of the half-sided wiring cord is hidden by the top cover member of the board box, etc., which reduces the workability of connection and reduces the size of the "hanging board". It is hard to discover.

[0012] Therefore, the present invention makes it possible to prevent an unauthorized component such as a "hanging board" from being easily attached without impairing the workability of connection of a wiring cord, and to find an attached unauthorized component. The purpose is to make it easier.

[0013]

According to a first aspect of the present invention, there is provided a gaming machine in which a control circuit board for controlling an electric operating device used in the gaming machine is housed in a board box. Various wiring cords extending from the actuator side have a connection terminal mounting area provided with each connection terminal mounting portion electrically connected via a connection terminal, the substrate box, the connection terminal mounting area An upper cover member and a bottom cover member that cover the control circuit board from the front side and the back side in the exposed state, and the connection terminal mounting area in a state where connection terminals of the various wiring cords are connected to the connection terminal mounting portions. And is formed in a substantially box shape with a bottom opening to cover
A cover member detachably attached to at least one of the upper lid member or the bottom lid member, wherein the cover member is formed using a material that allows the inside of the cover member to be seen through, and the cover terminal A notch is provided in one wall portion along the longitudinal direction, and various wiring cords in which connection terminals are connected to the connection terminal mounting portions are covered with the cover member attached to the upper lid member or the bottom lid member. The inside of the member was curved so that the cutout could pass through.

According to a second aspect of the present invention, in the first aspect, when the cover member is attached to the upper lid member or the bottom lid member, the cover portion is provided with a wall provided with the cutout portion in the connection terminal attachment region. It was formed by protruding a predetermined length outward.

In a third aspect based on the first and second aspects, the notch is cut to a predetermined height with respect to the connection terminal mounting area surface.

[0016]

According to the first and third aspects of the present invention, since the connection terminal mounting area of the control circuit board is covered by the cover member, the "hanging board" can be easily mounted on the control circuit board during the operation of the game store. Can be prevented. In addition, since the cover member is made of a transparent member, even if a small "hanging board" is attached to the control circuit board, it can be used to repair clogged balls in gaming machines during business hours, or for maintenance and inspection of gaming machines. "The hanging board" can be easily found by the clerk. In addition, the connection state between the various wiring cords and the connection terminal mounting portions, the state of the connection terminal mounting area can be confirmed, and the various wiring cords are bent inside the cover member,
Since it is led through the cutout side provided on the wall of the cover member along the longitudinal direction of the connection terminal mounting area, the blind spot obstructed by the wiring cord is small, and it is easier to find the `` hanging board '' Inspection work of the connection state, control circuit board, and the like can be easily performed. In addition, since the cover member is detachable, good workability of wiring connection can be obtained at the time of installation of the gaming machine, replacement of the gaming board, inspection, and the like. In addition, since the wiring cord is bent and guided inside the cover member, an excessive tensile force is not applied to the connection terminal portion of the wiring cord, and for example, some work is performed with the wiring extending from the board box. Also, even when the wiring is unintentionally pulled, the wiring cord can be prevented from coming loose from the connection terminal attachment portion and becoming loose.

According to the second aspect of the present invention, the wall portion provided with the notch portion of the cover member is formed so as to protrude outside the connection terminal mounting region by a predetermined length. Since the distance between the top cover member and the bottom cover member can be given a margin, the space formed by the cutout portion is widened, and the number of various wiring cords passing through this space can be increased.
