Description

  The present invention relates to a game board and a ball game machine, and more particularly to a ball game machine such as a pachinko machine and a smart ball, and a game board used therefor.

In pachinko halls where a large number of pachinko gaming devices are installed, new pachinko gaming devices are frequently replaced so as not to bore the player.
At that time, the display device having a variable display unit made of an expensive liquid crystal panel or the like and the game board are exchanged together, or the entire housing of the pachinko gaming machine is exchanged. As a result, it was very expensive. Moreover, at this time, even the components of the pachinko gaming machine that do not need to be exchanged are exchanged together. For example, liquid crystal panels and the like have been disposed of without being reused even though they have little deterioration and can be reused sufficiently.
Further, in the conventional pachinko gaming machine, the gaming board is provided with a display device that includes a variable display unit made of a liquid crystal panel or the like on the gaming board. Since a large number of wires are derived from the display device, it is difficult to replace only the game board while leaving the display device.

For solving this problem, for example, Patent Document 1 is known.
In this game board, a permeable front substrate made of a soft material and a permeable back substrate made of a hard material are used. The front board can be attached to and detached from the main body frame or back board of the ball game machine, and when changing the surface, only the front board on which the pattern film is arranged and the obstacle nail is implanted can be removed and replaced. It is a thing.
Examples of the soft material include transparent rubber such as ethylene-propylene rubber, chloroprene rubber, polyurethane rubber, polyvinyl chloride resin, polyethylene resin, and the like.
Examples of the hard material include acrylic resin, acrylonitrile-butadiene-styrene resin (ABS resin), and polycarbonate resin. The thickness of the front substrate was 2 to 4 mm, and the thickness of the back substrate was 1 to 3 mm.

However, the game board of Patent Document 1 is composed of a front substrate made of a soft material and a back substrate made of a hard material. For this reason, when the game board is manufactured, it is necessary to superimpose and bond the front substrate and the back substrate, or to screw them together, which makes it troublesome to superimpose both substrates.
Also, with transparent rubber such as ethylene-propylene rubber, chloroprene rubber, polyurethane rubber, and soft substrate made of polyvinyl chloride resin, polyethylene resin, etc., the material is too soft and the planting of obstacle nails is not stable Moreover, due to repeated nail adjustments in the pachinko hall, the nail hole of the front substrate became large, and the driven nail was easily rattled.

By the way, as a substrate of a conventional game board, it consists of a permeable single plate using a resin composition in which a large amount of plasticizer is blended with cellulose acetate resin such as cellulose diacetate or cellulose acetate butyrate. Many things are used. However, such a conventional substrate uses a large amount of plasticizer, so it is not friendly to the natural environment, and the plasticizer bleeds and hinders the slipperiness of the ball and the problem of clouding the display screen Has a point.
On the other hand, recently, a specific amount of polybutylene succinate is added to cellulose acetate butyrate, and the film obtained by the solution casting method has been shown to be excellent in transparency (Non-patent Document 1), There is no mention or suggestion about the use of the film.

  In the resin composition, the blending ratio of the (B) aliphatic polyester is usually 1 to 50% by weight, preferably 5 to 40% by weight. If it is less than 1% by weight, the flexibility of the resulting sheet is impaired, cracking occurs when nailing, and workability in molding equipment such as an extruder is deteriorated. On the other hand, if it exceeds 50% by weight, the haze value becomes high and the transparency is impaired.

If necessary, an antistatic agent, a stabilizer, an antioxidant, or a dye or pigment for adjusting the color tone may be added to the resin composition.
Moreover, a conventionally well-known method is used about the method of kneading these additives in a synthetic resin. For example, the synthetic resin, the antistatic agent and the stabilizer may be sufficiently mixed with a mixing stirrer and molded into a plate shape by an apparatus such as extrusion, block press, or casting.
