Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaming board of a gaming machine such as a pachinko machine, and particularly in a synthetic resin gaming board, the strength of the gaming board is reduced due to an increase in size of various attachment members such as an accessory attached to the gaming board and a display device. Further, the present invention relates to an improvement of a game board that prevents a reduction in mounting strength and a reduction in molding accuracy.
[0002]
[Prior art]
A gaming board of a gaming machine such as a pachinko machine is provided with a light emitting unit that appropriately emits light on the board surface, a movable accessory, a liquid crystal screen display device, and the like. These members such as the light emitting part and the accessory are generally formed individually from plastic or the like, and are fitted into respective mounting openings formed in advance on the surface of the game board. Therefore, the game board has a large number of mounting openings for incorporating display devices and the like.
[0003]
In addition, there are game boards mainly composed of wood, and those in which synthetic resin is molded integrally with the material. Recently, examples of molding integrally using synthetic resin materials are increasing. The mounting port is also integrally molded. In addition, since the gaming machine drops game balls along the game board, the flatness of the game board surface is important, and even when molding with synthetic resin, ribs are set up on the back surface or the plate thickness is increased. The shape accuracy is increased by adjusting the shape.
[0004]
On the other hand, in order to increase the interest of the player, the light emitting unit and the accessory attached to the game board, the screen of the display device, etc. are enlarged, and the game board is decorated with these various members to give changes, and various games The content is made to be done.
[0005]
[Problems to be solved by the invention]
However, if the attachment member attached to the game board such as an accessory is made large, the area of the attachment port formed in the game board for attaching these will be enlarged, and large openings will be formed in various parts of the game board. . Then, the strength of the game board is reduced, and a large attachment member is fixed to the attachment port with a large area, so that it is difficult to accurately align, and the attachment strength of the attachment member is also reduced. There was a thing.
[0006]
In addition, in a game board made of synthetic resin, when the game board is injection molded, the flow of resin in the mold is blocked by the mounting opening, and the resin does not fill the entire mold and the resin is cut halfway. In other words, so-called short welds may occur.
[0007]
Furthermore, since the molten resin injected into the mold flows away from the mounting opening, the molten resin does not flow smoothly in the mold, and the heat transfer speed in the mold varies greatly depending on the mounting opening. Since the curing time of the molten resin varies depending on the location, it is difficult to control the temperature of the mold, and distortion, sinking, warping, and the like may occur in the molded game board. When warping or distortion occurs in the game board, a serious problem may occur for the gaming machine in which the delicate ball flow control by the nail is hindered.
[0008]
An object of the present invention is to provide a game board in which no warpage or distortion occurs in the game board even when an attachment opening having a wide opening area is provided, and the attachment member can be firmly attached to the attachment opening. And
[0009]
[Means for Solving the Problems]
In the present invention, in order to solve the above-described problem, a reinforcing beam is attached to the back side of the game board in an attachment port formed in the game board. The beam should be mounted across the mounting port while avoiding the attachment members such as accessories attached to the mounting port, and the beam can be molded integrally with the game board by injection molding, or a separate beam part can be formed. It is good also as attaching a beam part to the periphery of an attachment port with a screw | thread etc. FIG. Further, the beam does not straddle the attachment port, and it is sufficient that at least the back side of the attachment member attached to the attachment port can be protected even if one side of the beam is not in contact with the game board.
[0010]
This prevents a decrease in the strength of the game board due to the mounting opening and a decrease in the mounting strength of the accessory, display device, etc. In addition, when the game board is integrally molded, the inside of the beam passed to the mounting opening is injected. Since the molten resin flows, the flow of the molten resin around the mounting opening can be made smooth, the temperature of the resin can be controlled reliably, and the occurrence of distortion, sink, warpage, etc. of the game board can be prevented.
[0011]
Further, since the beams are provided on the back side of the attachment member such as a display device, when the attachment member is attached to the game board, they can be protected by the beam. Furthermore, an attachment hole or the like may be provided in the beam, and an attachment member such as a display device may be assembled to the attachment hole. In this way, the mounting member can be positioned on the game board, and the mounting member can be fixed not only around the mounting port but also on the beam side. Can be strengthened.
Further, a plurality of reinforcing members are provided, the plurality of reinforcing members intersect with each other, and both ends of the plurality of reinforcing members are attached to the end portions of the mounting openings, and each of the plurality of reinforcing members is A plate-shaped member having a large surface and a small surface is used, and the large surface of the plate-shaped member is configured to face a direction substantially perpendicular to the board surface of the game board. By doing in this way, a stronger reinforcement can be performed by the reinforcing member.
