Description

  The present invention relates to a decorative sheet for a gaming machine used by being attached to a game board surface.

  As a decorative sheet to be attached to a game board surface of a gaming machine such as a pachinko machine, there is a sheet in which a transparent film made of a synthetic resin is attached to a printed surface of a backing paper on which a required pattern is printed. This decorative sheet is used so that its printed surface can be attached to the game board with the front side and the printed design can be seen through a transparent film. The game board on which the decorative sheet is affixed is provided with game parts such as nails, bonuses, and various winning holes.

When the gaming machine is worn out or the contents of the game become obsolete, the gaming machine is replaced with a new machine, but the used gaming machine is disassembled and partly recycled and reused. In addition, since such a process is costly, it may be discarded without being disassembled. However, since a conventional decorative sheet is made of a synthetic resin such as polyester or celluloid or cellulose acetate butyrate disclosed in JP-A-2003-38743 as a transparent film, such a decorative sheet is used. However, there is a disadvantage that it remains indefinitely without being easily decomposed even after being left for many years. In addition, the above-mentioned general-purpose synthetic resins have flame retardancy, and when incinerated, they generate harmful gases and pollute the atmosphere, so they cannot be disposed of as general waste. . Therefore, the conventional decorative sheet often becomes a problem for the disposal after disposal.
Furthermore, it is actually difficult to dispose of waste materials from pachinko machine bases, plant waste such as waste paper, or surplus crops such as corn for livestock feed, and these are used as raw materials for transparent films. If possible, it is very beneficial for recycling resources.
JP 2003-38743 A (FIG. 1)

  The present invention has been made in order to solve the above-described conventional problems and to provide a decorative sheet for a gaming machine having a high decomposition rate by effectively using plant waste and surplus crops.

  The gaming machine decorative sheet of the present invention made to solve the above problems is a gaming machine decorative sheet used by being attached to a gaming board surface, the decorative sheet comprising a transparent film, a backing paper, The pattern printing layer formed between them, and the transparent film is manufactured using a biodegradable plastic, and the decorative sheet is It consists of a transparent film and a pattern printing layer formed on the back surface of the transparent film, and the transparent film is manufactured using a biodegradable plastic.

  The pattern printing layer can be printed with biodegradable ink. In addition, as the biodegradable plastic, a fully degradable biodegradable plastic manufactured using plant waste as a raw material can be used, and a machine scrap material of a pachinko machine can be used as the plant waste. Furthermore, as the biodegradable plastic, a decay-type biodegradable plastic in which a plant-based natural polymer is mixed with a general-purpose synthetic resin can be used.

In the decorative sheet of the gaming machine of the present invention, since the transparent film constituting the decorative sheet is made of biodegradable plastic, the transparent film can be decomposed faster than before due to the decomposition action of microorganisms. Moreover, since the pattern printing layer is printed with biodegradable ink, it does not pollute the environment.
As a biodegradable plastic, a transparent film can be finally decomposed into harmless water, carbon dioxide and the like by using a fully degradable biodegradable plastic manufactured using plant waste as a raw material. By using the machine waste of the pachinko machine as the plant waste, the machine waste can be effectively utilized as a resource.
In addition, biodegradable plastics can be produced at low cost by using disintegrating biodegradable plastics, which are mixed with general-purpose synthetic resins, such as starch-derived plant-derived macromolecules from agricultural crops, especially surplus crops. In addition, it is possible to dispose of surplus crops and use them effectively.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
1 and 2 are diagrams showing a decorative sheet according to the present invention. The decorative sheet is a backing paper 3 in which a pattern printing layer 2 is formed on the back surface of a transparent film 1 manufactured using a biodegradable plastic. Is affixed. The pattern print layer 2 may be printed on the back surface of the transparent film 1. In this case, the backing paper 3 can be omitted.

  The biodegradable plastic is a fully degradable biodegradable plastic manufactured using plant waste as a raw material. As plant waste, used paper such as cardboard, flyers, recycled paper, raw garbage, surplus crops, wood flour, bamboo, straw, thinned wood, furniture waste, house demolition waste, pachinko machine stand waste However, when the machine base waste of the pachinko machine such as the machine frame and the plywood is used, the machine base waste can be used effectively, which is very preferable as a disposal method of the pachinko machine.

  Here, the completely degradable biodegradable plastic refers to a type in which all of the components constituting the plastic are finally decomposed into water, carbon dioxide and the like by the action of microorganisms. However, complete decomposition is not required even for a mixture of fillers and pigments, and these should have little influence on the natural world. In the production of such a biodegradable plastic, for example, first, plant fibers are taken out from the plant waste as described above. Next, cellulose, which is the main component of the plant fiber, is put in a buffer together with the cellulose-degrading enzyme to decompose the cellulose and take out sugar (polylactic acid). 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. And the transparent film which has a biodegradability of a complete decomposition | disassembly type | mold can be manufactured by forming this plastic in a sheet form.

  Completely degradable biodegradable plastics generate little heat even when incinerated, and no harmful substances such as dioxins are released. In addition, it can be returned to the original raw sugar by chemical decomposition. Therefore, since it can be recycled and used repeatedly, there is no fear of exhaustion like a limited oil resource.

  Alternatively, the biodegradable plastic may be replaced with a disintegrating (partially decomposing) biodegradable plastic in which a plant natural polymer is mixed with a general-purpose synthetic resin such as polyethylene or polypropylene. As the plant-based natural polymer, starch, chitosan, protein extracted from farm products such as corn for livestock feed, potato, and soybean can be used, and PVA (polyvinyl alcohol) can be added to these. In this disintegration-type biodegradable plastic, starch and the like are decomposed into microorganisms during the decomposition process, and the portion of the general-purpose synthetic resin that becomes the base material remains without being decomposed. However, since it collapses to a level that is recognized as being decomposed by the naked eye, it is not much different from a fully degradable biodegradable plastic. Although the degradation rate can be increased as the mixing ratio of the natural polymer is increased, the production cost of the transparent film is increased.

  The use of the decorative sheet of the gaming machine of the present invention is not limited to the gaming board surface of the pachinko machine, and can be used by sticking to the decorative surface of a gaming machine such as a slot machine. In addition, the biodegradable plastic used in the present invention is a pachinko machine ball tray, ball tank, ball guide rod, ornaments such as windmills and frame decorations, and all game parts that have conventionally used general-purpose synthetic resins. Can be used for

  In addition, it is desirable to print the pattern printing layer with biodegradable ink because it does not contaminate the environment. As such a biodegradable ink, a modified starch-based ink or an aliphatic polyester-based ink can be used.

  As described above, the decorative sheet for the gaming machine according to the present invention can be used effectively as a resource for plant waste and surplus crops, and can be quickly decomposed when left untreated. It has great value.

It is sectional drawing of the decoration sheet which concerns on this invention.
