  However, in the pachinko gaming machines according to Patent Documents 1 and 2, glass plates are bonded to the front and rear surfaces of the synthetic resin holding frame, respectively, and the synthetic resin member and the glass member are attached. Since each of them has to be formed separately, and it consists of three members, it is troublesome to assemble them as well as it takes time to manufacture them from different materials. For this reason, there is a problem that the workability is poor and the production cost is high. In addition, since two glass plates are used, the weight increases and it is difficult to handle, which is not preferable because a large load is applied to the transparent plate holding frame. Furthermore, since the transparent plate holding frame is made of a combination of different materials such as a synthetic resin holding frame and a glass plate, there is a problem that it is difficult to carry out separation work in the case of disposal or recycling.

  Therefore, the present invention has been made to solve the above-mentioned problems, and since it is formed from a single material and has few constituent members, it has good workability and can be manufactured at low cost. An object of the present invention is to provide a transparent plate unit that can be easily separated and disposed of when it is disposed or recycled.

  In order to achieve such an object, the transparent plate unit of the present invention is a transparent plate unit that covers the front surface of a game board disposed in a gaming machine, and is formed of a transparent hard high-strength synthetic resin.

  The transparent plate unit of the present invention is a transparent plate unit that covers the front surface of a game board disposed in a gaming machine, and is formed into a flat hollow shape by integral molding with a transparent hard high-strength synthetic resin. It is characterized by comprising a pair of see-through plate portions that are separated and arranged in parallel so as to cover the front surface of each other.

  The transparent plate unit according to the present invention is formed of a transparent hard high-strength synthetic resin and is arranged in parallel so as to cover the front surface of the game board, and at least one of the opposing surfaces of these transparent plates The distance holding projections are integrally protruded from each other, and the distance holding projections are bonded or welded to a see-through plate facing the space-holding projections so that the two see-through plates are fixed at a predetermined interval. In this way, since the transparent plate unit is formed from a single material and has few constituent members, it is easy to assemble without being troublesome to manufacture them, the workability is good, and the manufacturing cost can be reduced. There is. Moreover, since the transparent plate unit is entirely made of a synthetic resin, it is suitable for weight reduction and easy handling, and a large load is not applied to the transparent plate holding frame. Furthermore, there is also an effect that the separation work in the case of disposal or recycling can be easily performed.

  In addition, there is a transparent plate unit that is formed into a flat hollow shape by integral molding with a transparent hard high-strength synthetic resin, and includes a pair of see-through plate portions that are separated and arranged in parallel so as to cover the front surface of the game board. In addition, since the transparent plate unit is made of a single component member, the manufacturing process is very simple and the assembly is not necessary, and the workability is excellent and the manufacturing cost can be further reduced. Also in this case, the transparent plate unit is preferably made of a synthetic resin as a whole, so that it is light in weight and easy to handle, and a large load is not applied to the transparent plate holding frame.

  Hereinafter, the best embodiment of the transparent plate unit according to the present invention will be described in detail. First, the present invention is applied to a gaming machine such as a pachinko gaming machine, an arrangement ball gaming machine, or a sparrow ball gaming machine. Of these, a case where the present invention is applied to a pachinko gaming machine will be described. Further, as the transparent synthetic resin used in the transparent plate unit of the present invention, for example, a hard high-strength synthetic resin that is hard and strong in strength such as engineering plastic is selected. For example, there are polycarbonate resin, acrylic resin, and polypropylene resin.

  Recently, a hard high-strength synthetic resin that exhibits a strength 2 to 5 times that of a steel plate using a polypropylene resin has been developed. The hard high-strength synthetic resin is cooled to below the melting point so as not to harden the polypropylene resin melted at high temperature, and the supercooled melt is momentarily pressed to crush it at once, and crystallizes while stretching the string-like molecules. Molded by the method. Thus, when the string-like molecules are stretched and crystallized, a synthetic resin that is hard and strong in strength is formed. A hard high-strength synthetic resin formed from a polypropylene resin and having a strength 2 to 5 times that of a steel plate is optimal as a synthetic resin applicable to the present invention.

  FIG. 1 is a perspective view of a transparent plate unit according to the present invention, FIG. 2 (a) is a perspective view showing an assembly process of the transparent plate unit, and (b) is an enlarged sectional view of the same part. The transparent plate unit A is formed in a substantially circular shape when viewed from the front. This is because, as will be described later, the window opening 11 that is opened in the transparent plate holding frame 10 and looks into the front game portion of the game board (not shown) is formed in a substantially circular shape. The transparent plate unit A includes a pair of perspective plates, that is, a front side perspective plate 1 and a rear side perspective plate 2. These front and rear see-through plates 1 and 2 are formed by, for example, injection molding.

  A plurality of spacing holding projections 3 projecting toward the front fluoroscopic plate 1 along the outer peripheral edge thereof are integrally provided on the front surface 2a of the rear fluoroscopic plate 2 facing the front fluoroscopic plate 1. In addition, each spacing holding projection is positioned on the rear surface 1a of the front side viewing plate 1 facing the rear viewing plate 2 so as to correspond to each spacing holding projection 3 protruding along the outer peripheral edge of the rear viewing plate 2. A mounting recess 4 into which the tip of 3 is inserted is provided. These mounting recesses 4 also play a role of positioning when the rear perspective plate 2 is attached to the front perspective plate 1. On the outer peripheral end face of the rear see-through plate 2, mounting pieces 5 for attaching the transparent plate unit A to the rear face of the transparent plate holding frame 10 at four places on the outer periphery that are substantially equally divided are the front face 2a of the rear see-through plate 2. And projecting so as to be located in a plane parallel to.

  Therefore, an adhesive (not shown) is applied to the tip of each spacing holding projection 3 of the rear see-through plate 2 so that the front seeing plate 1 and the rear seeing plate 2 are opposed to each other. 3 and the mounting recesses 4 facing each other, they are brought close to each other, and the tip portions of the spacing holding projections 3 are fitted into the mounting recesses 4. As a result, the front and rear see-through plates 1 and 2 are arranged side by side so as to be separated from each other by a predetermined distance and overlap when viewed from the front side. The transparent plate unit A thus manufactured is mounted on the rear surface of the transparent plate holding frame 10 as shown in FIG. Each spacing holding projection 3 and each mounting recess 4 may be welded by applying ultrasonic waves to the site in a state where the spacing holding projection 3 is fitted into the mounting recess 4 without using an adhesive. . Even in this case, the front and rear see-through plates 1 and 2 are similarly arranged in parallel so as to be separated from each other for a predetermined period and overlap when viewed from the front side. In this embodiment, the spacing holding projection 3 is provided on the front surface 2a of the rear see-through plate 2, but conversely, it may be provided on the rear surface 1a of the front see-through plate 1. Further, the spacing holding projections 3 may be provided separately on the rear surface 1a of the front see-through plate 1 and the front surface 2a of the rear see-through plate 2.

  The transparent plate holding frame 10 will be described with reference to FIG. 3. The transparent plate holding frame 10 is attached to the front surface of a pachinko gaming machine (not shown) so as to be openable and closable, and exclusively covers the front side of the game portion of the game board. The transparent plate holding frame 10 is provided with a large circular window opening 11 so that the game portion of the game board can be seen from the front side. Then, the transparent plate unit A is mounted on the rear surface of the transparent plate holding frame 10 so as to close the window opening 11.

The engaging projection piece 12 is attached to the shaft. Each engagement protrusion 12 is attached to a support shaft 13 provided on the transparent plate holding frame 10, and each engagement protrusion 12 is rotated about the support shaft 13 along the rear surface of the transparent plate holding frame 10 with a fingertip. The projecting piece 12 is freely rotatable. In this case, it is preferable that a compression or tension coil spring (not shown) is wound around the support shaft 13, and each attachment piece 5 is pressed to the rear surface side of the transparent plate holding frame 10 by each engagement protrusion 12. In this way, the transparent plate unit A can be firmly fixed without rattling. In addition, a transparent plate platform 14 on which the transparent plate unit A is placed is integrally provided on the rear surface of the transparent plate holding frame 10 and outside the lower edge of the window opening 11. Therefore, the lower surface of the transparent plate unit A is placed on the upper surface of the transparent plate mount 14 so that the front see-through plate 1 is directed to the window opening 11 and temporarily held. In this state, each engagement protrusion 12 is rotated in a predetermined direction along the rear surface of the transparent plate holding frame 10 and engaged with each attachment piece 5.

  Thereby, the transparent plate unit A is mounted on the rear surface of the transparent plate holding frame 10. In this way, the transparent plate holding frame 10 to which the transparent plate unit A is mounted is a pachinko gaming machine (not shown) and covers the front surface of the game portion of the game board on the front surface of the main body frame on which the game board is disposed. Then, it is pivotally attached so that it can be freely opened and closed. The player enjoys the game by visually recognizing the game portion of the game board through the window opening 11 and further through the transparent plate unit A from the front side of the pachinko gaming machine.

  The transparent plate unit A according to the present invention is formed of a transparent hard high-strength synthetic resin, and is arranged in parallel so as to cover the front surface of the game board, and these front and rear side plates And a spacing holding projection 3 that is integrally projected on at least one of the opposing surfaces of the see-through plates 1 and 2. Then, the front projection plate 1 and the rear see-through plate 2 are fixed to each other with a predetermined interval by adhering or welding the spacing holding projections 3 to the front see-through plate 1 or the rear see-through plate 2 opposed thereto. Thus, since the transparent plate unit A is formed from a single material and has few constituent members, it is easy to assemble without assembling them. Further, since the transparent plate unit A is entirely made of a synthetic resin, it is light and easy to handle. Furthermore, separation work for disposal or recycling can be easily performed.

  Next, another transparent plate unit B according to the present invention will be described. 4A is a perspective view of another transparent plate unit according to the present invention, FIG. 4B is an enlarged sectional view of the same part, and FIG. 5 is a perspective view showing a state in which the transparent plate unit is mounted on the transparent plate holding frame. is there. The material used for the other transparent plate unit B is also selected from a transparent resin material, that is, a hard high-strength synthetic resin that is hard and strong in strength, such as the engineering plastic. For example, there are polycarbonate resin, acrylic resin, and polypropylene resin. In addition, a hard high-strength synthetic resin formed from a polypropylene resin as described above and having a strength 2 to 5 times that of a steel plate is also optimal in this case.

  The other transparent plate unit B is formed in a substantially square shape when viewed from the front. This is because, as will be described later, a window opening 21 that is opened in the transparent plate holding frame 20 and looks into a game portion of a game board (not shown) is formed in a substantially square shape. The other transparent plate unit B is formed in a flat hollow shape. In this case, one of the pair of parallel flat side walls having a large area is the front side seeing plate portion 6a, and the other side opposite thereto is the rear side seeing plate portion 6b. In addition, the front see-through plate portion 6a and the rear see-through plate portion 6b are separated from each other by a predetermined distance, and one side surface of the front and rear see-through plate portions 6a, 6b is opened, and the opening The other transparent plate unit B is mounted on the rear surface of the transparent plate holding frame 20 so that 7 becomes the lower surface. The other transparent plate unit B is integrally formed by, for example, injection molding. In this case, if the other side facing the one side provided with the opening 7 is also opened, the other transparent plate unit B is formed by, for example, extrusion molding.

  Similar to the transparent plate unit A, the other transparent plate unit B holds the other transparent plate unit B on both side plate portions 8 and 8 between the front side seeing plate portion 6a and the rear side seeing plate portion 6b. Mounting pieces 9 for mounting on the rear surface of the frame 20 are provided so as to protrude from the top and bottom of each side plate portion 8. These mounting pieces 9 are also provided so as to be positioned in a plane parallel to the front surface of the front see-through plate portion 6a.

  On the rear surface of the transparent plate holding frame 20, engaging protrusions 22 that engage with the mounting pieces 9 at the positions corresponding to the mounting pieces 9 along the outer peripheral edge of the window opening 21 are pivotally attached. Similarly to the above, each engagement protrusion 22 is attached to a support shaft 23 provided on the transparent plate holding frame 20, and is rotated along the rear surface of the transparent plate holding frame 10 with a fingertip around the support shaft 23. Thus, each engaging protrusion 22 is freely rotated. Also in this case, it is preferable that a compression or tension coil spring (not shown) is wound around the support shaft 23 and each attachment piece 9 is pressed to the rear surface side of the transparent plate holding frame 20 by each engagement protrusion piece 22. In this way, the transparent plate unit B can be firmly fixed without rattling. In addition, a transparent plate platform 24 on which another transparent plate unit B is mounted is integrally provided on the rear surface of the transparent plate holding frame 20 and outside the lower edge of the window opening 21. Therefore, the lower surface of the other transparent plate unit B is placed on the upper surface of the transparent plate mount 24 so that the front see-through plate portion 6a is directed to the window opening 21, and is temporarily held. In this state, each engagement protrusion 22 is rotated in a predetermined direction along the rear surface of the transparent plate holding frame 20 to be engaged with each attachment piece 9.

  As a result, another transparent plate unit B is mounted on the rear surface of the transparent plate holding frame 20. Thus, the transparent plate holding frame 20 to which the other transparent plate unit B is mounted is a pachinko gaming machine (not shown), and the front side of the gaming portion of the gaming board is placed on the front surface of the main body frame on which the gaming board is arranged. It is pivotally attached so that it can be opened and closed. The player enjoys the game by visually recognizing the game portion of the game board through the window opening 21 and the other transparent plate unit B from the front side of the pachinko gaming machine.

  Thus, the other transparent plate unit B according to the present invention is formed into a flat hollow shape by integral molding with a transparent hard high-strength synthetic resin, and a pair of front and rear sides arranged side by side so as to cover the front surface of the game board Since the side see-through plate portions 6a and 6b are provided and are made of a single component, the manufacturing is extremely simple and there is no need for assembly. Also in this case, since the other transparent plate unit is entirely made of a synthetic resin material, the weight is reduced and the handling is easy. Furthermore, separation work for disposal or recycling can be easily performed.
