Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a game board used in a gaming machine such as a pachinko machine.
[0002]
[Prior art]
In the game board of the pachinko machine, a transparent decorative sheet printed with a pattern is pasted on the front of the game board, and various winning devices, variable display devices, and the like are surrounded by an annular guide rail. Various game parts such as an illumination lamp are arranged.
By the way, in recent years, from the viewpoint of protecting the global environment, such a game board must also use plant waste, etc., can be recycled, or should not pollute the environment when discarded. Etc. are demanded. For example, Japanese Patent No. 2732724 discloses a game board based on a molded body made of synthetic resin, particularly ABS resin. Japanese Patent No. 2966380 discloses a method of manufacturing a game board that is molded using polyethylene. However, when a game board is manufactured only from general-purpose synthetic resins such as ABS resin and polyethylene, no plant waste can be used. In addition, game boards made from synthetic resin alone are flame retardant and cannot be disposed of as general waste, and are not easily disassembled when disposed of in landfills. There are problems such as destruction.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view showing a game area of a pachinko gaming machine, in which a large number of nails 12 are driven into a game area 11 of a game board 1 surrounded by an annular guide rail 10, and a symbol start prize is obtained. Game parts such as a mouth 2, a specific winning opening 3, a third type starting winning opening 4, a large winning opening 5, an accessory 7 having a variable display device 6, an impeller 8, and an illumination lamp 9 are arranged.
[0008]
The above-mentioned pachinko gaming machine is of the right-handed type, and when a ball wins the symbol start winning opening 2, the display state of the variable display device 6 starts to fluctuate and is stopped after a certain time, and the variable display device that has stopped When the display results of 6 are aligned with the preset display, the specific winning opening 3 is opened. Then, when the ball wins the specific winning opening 3, a jackpot right is generated. When the right is generated, when a ball wins the third type start winning opening 4, the jackpot is determined, and the big winning opening 5 is opened, and a predetermined number of balls or a predetermined number of balls can be received. If the ball wins the start winning opening 4 during the jackpot final determination period, the jackpot right for the next round can be obtained. And, it is possible to repeat up to 16 times, with the grand prize opening 5 being opened once by winning the start prize opening 4.
[0009]
Here, in this embodiment, the game board 1 is formed of a molding material in which plant waste and a thermoplastic resin are mixed and kneaded. Waste paper such as cardboard, flyers and recycled paper, wood flour, bamboo, straw, thinned wood, waste from furniture, waste from dismantling houses can be used as plant waste, but waste paper or plant fibers taken from this waste paper are used. However, it is desirable because molding conditions such as fluidity during molding are stabilized.
[0010]
A general-purpose synthetic resin such as polyethylene or polypropylene is mixed with plant waste such as waste paper and kneaded to obtain a molding raw material. Since the game board 1 molded from this molding raw material can be disposed of as combustible garbage as well as general garbage such as paper, a flame-retardant material such as the game board 1 made of only a general-purpose synthetic resin of vinyl polymerization type. As a result, it is possible to omit the trouble of sorting. In addition, waste paper that is waste can be used effectively. When used paper is mixed with a general-purpose synthetic resin, it is desirable that the amount of used paper be 50% or more because the environment-friendly game board 1 mainly composed of used paper can be formed.
[0011]
Further, as the thermoplastic resin, a plant resin synthesized from sugar extracted from plant waste and decomposing cellulose extracted as a main component of the plant fiber can be used. This plant-based thermoplastic resin is a recyclable plastic that is biodegradable and photodegradable and can be recycled. A molded body, that is, the game board 1 can be manufactured by mixing waste paper or the like with such a thermoplastic resin to form a molding raw material, and then performing injection molding, extrusion molding, or compression molding.
[0012]
The manufacturing process of the thermoplastic resin and molded object from plant waste is shown in FIG. First, plant fibers are taken out from used paper such as cardboard, flyers and recycled paper. Next, cellulose, which is the main component of the plant fiber, is put into a buffer together with cellulase (cellulose-degrading enzyme) to decompose the cellulose and take out sugar (polylactic acid). Color materials such as printing ink and toner adhering to the waste paper can be removed at this stage. Next, a biodegradable and photodegradable plastic can be synthesized by adding a fatty acid such as dicarboxylic acid to the recovered sugar and copolymerizing it. A game board 1 as shown in FIG. 3 can be manufactured by using, as a forming raw material, a small piece obtained by cutting waste paper or the like into this plastic, or a mixture of kneaded plant fibers extracted from waste paper or the like.
[0013]
Since sugar is expensive, plant waste such as waste paper and plant fiber is mixed as a filler (filler) in a larger amount than the amount of the thermoplastic resin, and kneaded and diluted to obtain an inexpensive molding raw material. Thereby, the game board 1 can be manufactured at a very low cost. The mixing ratio of the plant waste is preferably 1 to 4 with respect to the thermoplastic resin 1.
[0014]
Moreover, what mixed the biodegradable plastics with general-purpose synthetic resins, such as a polypropylene, and was made into the partial decomposition | disassembly (degradation) type biodegradable plastic can also be used as a thermoplastic resin. This partially degradable biodegradable plastic is suitable for an environment having the same level of degradability as a normal fully degradable biodegradable plastic. The mixing ratio of the biodegradable plastic is preferably 1% or more in order to increase the decomposition rate, and more preferably 10% or more. The decomposition speed of the game board 1 can be increased as the mixing ratio is increased.
[0015]
The above thermoplastic resin can be reduced in density and reduced in weight by forming a foam by foaming at the time of molding using a normal foaming agent such as azodicarbonamide. Moreover, the density of a thermoplastic resin can be made small also by mixing the foamed polyethylene etc. which were foamed previously with a thermoplastic resin.
[0016]
Then, the molded game board 1 can be nailed by cooling and solidifying the molding raw material by injection molding or the like. Alternatively, it is possible to manufacture the game board 1 having a toughness that ensures toughness by adjusting the amount of used paper, vegetable fiber, and the like to be kneaded. In addition, a fluidizing agent for securing fluidity and a bleaching agent for waste paper can be appropriately added to the forming raw material.
[0017]
In the case where the molded game board 1 is soft so that it cannot securely hold the nail that has been struck and is wobbled by a ball collision, as shown in FIG. 4, the surface of the plywood board The game board 1 can be manufactured by injecting, extruding, etc. the molding raw material and having the plywood board inserted therein and the molding raw material is integrally coated on the surface of the plywood board. In this way, the game board 1 is reinforced by the plywood board, so that the nail can be reliably supported. Therefore, plant waste can be used effectively and consumption of plywood can be suppressed.
[0018]
As described above, since the forming raw material is produced from plant waste such as waste paper, plant waste that has been disposed of in the past can be effectively used as a resource. Biodegradable plastics produced from waste paper etc. are decomposed into water and carbon dioxide by natural microorganisms and degrading enzymes after use. For this reason, landfill disposal is possible, and even when incinerated, the amount of generated heat is small and no harmful substances such as dioxins are released. Biodegradable plastics can be returned to the original raw sugar by chemical recycling (chemical decomposition). Therefore, since it can be recycled and used repeatedly, there is no fear of exhaustion like a limited oil resource.
[0019]
【The invention's effect】
As described above, the game board for gaming machine of the present invention is formed from a molding raw material in which plant waste such as waste paper and general-purpose synthetic resin such as polypropylene are mixed and kneaded. Waste can be used effectively and can be disposed of as general waste after use, eliminating the need for separate collection.
In addition, when molded using a biodegradable plastic synthesized from sugar obtained by decomposing cellulose such as waste paper as a thermoplastic resin, the game board shall be biodegradable and photodegradable. Since it can be used, it can be disposed of in landfills after use, and even when incinerated, it generates little heat and does not release dioxins or other harmful substances.
Moreover, the density of a thermoplastic resin can be made small and weight reduction can be achieved by making a thermoplastic resin into a foam or mixing a foam with a thermoplastic resin.
Furthermore, by integrally covering the surface of the plywood with the molding material, a game board that can reliably support the nail can be manufactured using plant waste.
Therefore, the present invention has extremely great value as it can provide a game board for an environment-friendly game machine by effectively using plant waste such as waste paper.
