DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine provided in a ball game machine such as a pachinko game machine (hereinafter referred to as a "pachinko machine" and collectively referred to as a "ball game machine") or an arrangement ball game machine. Related to panel equipment.

[0002]

2. Description of the Related Art A game board device which is provided on the back of a conventional game board and serves as a mounting base for a prize ball passage and a game control board is integrally structured and fixed around the game board with screws or the like. Is referred to as a slide device, and the slide device is fixed to a game board device with screws. A game control board is detachably attached to the rail of the slide device, and further secured with screws or springs so that the game control board does not fall off the slide device.

When a control board is attached, a harness with a connector is inserted into the control board.
The harness can be easily attached and detached. On the table of the game board, a prize hole or a windmill is attached, and in particular, a game machine with a first-class special electric accessory (hereinafter referred to as a first class) or a game with a second class special electric accessory that has a special prize hole Machines (hereinafter referred to as the second type) and the like tend to be clogged due to the structure of the game balls as a cascade of balls, and the prize ball is provided with a groove with the same length and angle as the path in the path of the winning ball. It has been proposed to install a horizontal groove to break the cascade. Also, when attaching and detaching the game control board, the length of the harness is made longer so that the harness can be easily inserted and removed, and anyone can easily exchange the game control board.

As disclosed in Japanese Examined Patent Publication No. 5-2216, the game board device is fixed with screws so that the winning game ball is guided inside each upright rib or the guiding L-rail and flows to the winning detecting device. What is being done,
There is also a method in which a guide rib of a winning ball is provided on the back side of a game board by a method of opening the entire game board apparatus to the right by a hinge provided on a mechanism board as disclosed in Japanese Patent Application Laid-Open No. H11-157,086. The prize-winning tool provided on the game board is provided with an electric portion such as a lamp or a solenoid, and there is a wiring connection method disclosed in Japanese Patent No. 1803365.

[0005]

However, if the game board device is fixed with screws, the prize balls (game balls) which are won from the respective winning ports and are gathered inside mesh with each other, and if more prizes continue, a dumpling shape is formed. And prize balls will not be paid out. All of the winning balls caught in the dumpling shape cannot be discharged unless the lowermost portion of the winning ball is broken. This has the drawback that the ball-shaped winning ball cannot be broken unless the gaming board device is once removed, whereas the open / close door type disclosed in Japanese Utility Model Publication No. 6-144 is available. With this opening / closing door system, when the game board device is opened, the electric control board is first turned and opened, but the harness of the circuit board to be connected is set to the length of the turning range, and when the electric control board is closed, the circuit is closed. The base harness becomes slack. This slack may be applied by any means, but if the circuit board harness is lengthened, it is possible to perform fraudulent acts such as installing a board that is likely to be a big hit etc. Become. In addition, when the opening / closing door type game board device connected to this mechanism board is provided to be opened sideways, the right side where the hinge mechanism is provided is an opening area opened in the mechanism board in relation to the hinge mechanism and the prize ball payout apparatus. Is limited, and if a mechanical winning device such as a side tulip is provided, it is impossible to cope with renju.

Another drawback of the horizontal opening is that because of the mechanism panel hinge mechanism, the opening / closing door cannot be set at a fixed position, and an L rail for guiding a winning ball is provided in the opening / closing door. It is very difficult. It is because of the positional relationship between the exit leading from the winning opening and the L rail for guidance, if it is higher than the exit, the winning ball stops at the exit, if it is lower than the exit, it will bounce due to the head drop and it may bite with the winning ball next won. . As a countermeasure, the L-rail for guidance must be directly hit on the back of the game board, which increases the manufacturing cost.

[0007] In the collecting gutter shown in Japanese Patent Publication No. 7-100080, if the above-mentioned biting occurs, it is impossible to loosen the beads without removing the collecting plate itself, and wiring is laid on the back side. It is very troublesome because there is. Here, if the positional relationship in which the game balls overlap is described, the game balls are engraved, and there is a non-slip phenomenon between the game balls and the game balls due to the engraving, so that a specific positional relationship cannot be maintained. Rolling brake is applied. The fact that the brakes are applied means that when overlapping at less than 1/4 of the game ball, the lower game ball brakes the upper game ball, and when it overlaps 3/4 or more, the upper game ball becomes the lower game ball. Like braking. Therefore, the localization overlap of the game balls is 1/4 at the position aligned with the hexahedral structure, and the honeycomb state of the 3/4 state naturally collapses. Next, a hinge mechanism is provided at the top and bottom of the opening and closing door of this mechanism panel. If a vertical hole for the hinge mechanism is provided in the plastic molding of the opening and closing door itself, a punching die for the hinge is required, and the hinge member is attached. In that case the part must be needed. That is, the cost is increased in any case.

Next, as described in Japanese Patent Publication No. 1-26311, a description of the contents divided into the types of winnings by partitions,
Even the contents disclosed in Japanese Patent Publication No. Hei 4-213508, which is very similar to the Japanese Patent Publication No. Hei 1-26311, have no means to suppress the passing speed of the game balls, and the drop impact may cause the bottom of the gutter to be damaged. In the amusement arcades, the troublesome work of repairing gutters is often seen. The present invention has been made in view of the above-mentioned drawbacks, and provides an excellent game board device.

[0009]

The above-described embodiment has other excellent components. First, a security device is provided, and it is possible to monitor installation of the unauthorized game control base without permission.

In this monitoring system, only the maintenance personnel authorized by the public are allowed to attach / detach the game control board. The pachinko machine must clearly indicate that the game control board has been attached / detached, and report it to the government. The game board device of the present invention can be said to have an excellent effect also in this point because it is obliged to do so. Secondly, a groove for preventing warpage is provided, and the provision of the groove for preventing warpage causes a depletion of a beech material, which is a raw material of a game board, so that some Lauan wood is inevitably used.

The partly used material is called a mix material, and a technique has been developed in which the lauan material is put inside and a beech material is bonded to the outside at the stage of manufacturing the veneer board which is the basis of the game board. More veneer boards are now available. However, since the elemental structure, which is a drawback of Rawan wood, has a fine space inside, when used as a game board because the adhesive for laminating is infiltrated, or there is uneven adhesion Unusual warping occurs due to overdrying. Thus, when a groove is provided by setting the position where warping is likely to occur, the depth and width of the groove, the warping force is collected by this groove, and the warpage can be prevented. Therefore, it can be said that a pachinko machine using a game board provided with grooves is a very effective means in terms of cost and environment. The above-described inner frame control line connector 71 and security connector 83 are both female type and are buried inside. The inner frame control line connector 71 is screwed into the base seat 84 at a mounting portion of the inner frame control line connector 71 (not shown). The security connector 83 is fixed to the security device 47 with a screw at a mounting portion of the security connector 83 (not shown).

The inner frame control line connector 71 and the security connector 83 are both submerged, and the connector (not shown) of the opponent game board control device 28 is also of a male type. It can be easily installed simply by knocking 44 down. This is the game board controller 2
8, a recessed portion (not shown) is placed on the slide rail 70, and a connecting device (not shown) is connected to the base lock lever 44 to pull the slide rail 70 rightward and further into the base seat 84. Therefore, anyone can easily perform the mounting work, and the labor of the assembling work can be saved.
