Description

  The present invention relates to a gaming machine such as a slot machine, and more particularly to a cabinet structure having a shielding function.

  A gaming machine such as a slot machine is generally composed of a cabinet and an electronic control unit housed in the cabinet. In general, a wooden board material is used for the cabinet in consideration of tactile sensation, weight, and workability, and the cabinet is formed by being combined in a box shape. The electronic control unit is operated by a player's operation to control the execution of the game, and includes an integrated circuit element such as a microcomputer, electronic components, and the like. Electronic control units may be affected by noise such as electromagnetic waves, and measures such as an electric shield layer are often provided on the cabinet side to prevent malfunctions and illegal games.

For example, in an electronic game machine disclosed in Patent Document 1, an aluminum foil is attached to the inner surface of a wall plate material, and a shield layer is formed by connecting aluminum foils of adjacent wall plate materials. In addition, an iron plate is provided inside the cabinet to double the wall plate, and a method of applying a conductive paint has also been proposed. In either case, the outside of the electronic control unit is covered with an electric shield layer to block the passage of electromagnetic waves, and noise resistance is improved.

  By the way, in the metal foil-attached plate material in which aluminum foil or the like is pasted on the wood-based plate material, there is a problem that the workability of the cabinet is extremely low. The cabinet requires a large number of notches, fixing holes, ventilation holes, and the like for attaching members, and is drilled. Here, when drilling a plate with metal foil, if a cutting tool for low speed operation for woodworking is used, the blade surface is significantly worn out by the metal foil, so that it is polished at a frequency of 100 times or more compared with normal wood processing. It was necessary to do this, and there was a risk of breakage of the cutting tool. On the other hand, if a high-speed cutting tool for metal processing is used, the wood-based plate material may be overheated due to high-speed friction and burn out.

  The method of duplicating the wall board with the wood-based board material and the iron board requires that the two holes be separately perforated, which is troublesome twice, and it is not easy to match the hole positions.

  The method of applying a conductive coating to a wood-based board as a wall board can solve the problem of drilling, but is insufficient in terms of paint cost and lead time. That is, the wood-based board material is highly impregnated, and when an expensive conductive paint is applied, not only the surface but also the inside is impregnated, so a large amount of paint is required and the cost is high. In addition, when proceeding to the next step such as drilling or assembly, a long waiting time is required until the impregnated paint dries.

  The present invention has been made in view of the above background, and is a gaming machine having a cabinet that has good workability such as drilling, can be manufactured with a short lead time, and is excellent in economy. provide.

  A gaming machine according to the present invention is a gaming machine including a cabinet formed of a wall plate material and an electronic control unit disposed inside the cabinet, wherein at least a part of the wall plate material is a sheet-like shape. A conductive sheet material comprising a base material and a conductive coating layer formed by applying a conductive paint on at least one surface of the base material; and a wood-based board material to which the conductive sheet material is affixed on at least one side. It is characterized by becoming. The base material is preferably a paper material.

  The gist of the present invention is to use a wall sheet material composed of a conductive sheet material coated with a conductive paint on a base material such as paper material and a wooden board material to which the conductive paint material is applied in order to impart a shielding function to the cabinet. To do.

  The cabinet can be formed by combining a plurality of wall plates, for example, in a front open box shape. As a wall board material, the thing which stuck the electrically conductive sheet material to the wood type board material is used. As the wood-based board material, MDF (Medium Density Fiberboad, medium density fiber board) and particle board which are processed wood products can be used, and normal wood or plywood may be used.

  The conductive sheet material can be manufactured by coating a conductive paint on at least one surface of a sheet-like substrate to form a conductive coating layer. Although a coating layer can be formed on both sides of the base material to enhance the shielding effect, extra paint and labor are required, so it is selected in consideration of cost effectiveness. As the conductive paint, for example, a commercial product containing fine silver particles can be used. It is preferable that specifications such as the type and ratio of the metal contained in the paint are selected in accordance with the desired shielding effect, and the thickness of the coating layer is also set appropriately. The base material is preferably a paper material, the coating layer is reliably formed, and drying can be completed in a short time. The base material is not limited to a paper material, and a thin film made of a polymer resin can also be used.

  The conductive coating layer may be coated with a coating roller. Further, the conductive coating layer may be painted by a printing machine. The coating method is not particularly limited, but it is preferable to apply a long paper material in a short time using a coating roller or a printing machine. The conductive paint is preferably coated in a short time or while stirring the paint because the contained metal particles separate and precipitate over time. In addition, the paint loss rate can be reduced to 5% or less for painting rollers and 10% or less for printing presses. Compared with spray spraying, about half of the paint is scattered in the air. Is efficient. Furthermore, these two methods have an effect of making the thickness of the coating layer uniform, compared with spraying or brushing by spraying, and are excellent in economic efficiency.

  The conductive sheet material can be attached to the wood-based plate material using an adhesive or the like. Usually, the conductive sheet material is preferably attached to the entire surface of the wood-based board material, but may be omitted if there is an unnecessary portion in terms of shielding performance. Further, the surface to be attached may be any of an inner surface, an outer surface, and both surfaces when assembled as a cabinet. For example, a conductive sheet material may be affixed to the inner surface and a cover material may be affixed to the outer surface. Or you may make it affix on an outer surface in order of a conductive sheet material and a surface covering material.

  The wall board material in which the conductive sheet material is pasted to the wooden board material can be finished in a cabinet by performing drilling and assembly in the next process. The perforating process may be performed in a plate material state before assembly, or may be performed in a box state after assembly. In any case, since the conductive sheet material and the wooden board material can be co-processed with the woodworking cutting tool, the workability is extremely good, and the wear on the blade surface is not different from that during normal wood processing.

  You may make it have a conduction | electrical_connection means which conducts between the electrically conductive coating-film layers of the said wall board material. When a plurality of wall plates are assembled, the conductive coating layers are brought into contact with each other to cause conduction, and a conduction means may be provided in order to ensure this conduction. Examples of the conduction means include performing additional coating between the conductive coating layers, and using L-shaped metal fittings for both assembling and ensuring conduction.

  In the above description, the conductive sheet material is manufactured and then pasted on the wood-based board material. However, the manufacturing order may be reversed. That is, first, a base material may be attached to a wooden board, and then a conductive paint may be applied to the surface of the base material.

  A gaming machine can be configured by assembling an electronic control unit inside the cabinet formed as described above. Since the electronic control unit may be the same as the conventional one, a detailed description is omitted.

  Since the gaming machine of the present invention includes a cabinet formed of a wall plate made of a conductive sheet material and a wood-based plate material, it has good workability including drilling and can be manufactured with a short lead time. It is. Moreover, in the aspect in which the conductive coating layer is applied by a coating roller or a printing machine, the loss rate of the coating can be kept low, and the thickness of the coating layer can be made uniform, which is economical. Excellent in properties.

  The best mode for carrying out the present invention will be described with reference to FIGS. FIG. 1 is a diagram illustrating a cabinet of a gaming machine according to an embodiment of the present invention. The cabinet 1 is formed in a box shape with an open front by combining five wall plate materials of a bottom plate 21, a back plate 22, a top plate 23, a right side plate 24, and a left side plate 25. An unillustrated door is disposed in the front opening so as to be openable and closable. An electronic control unit (not shown) is disposed inside the cabinet 1, and various members forming a display unit, an operation unit, and the like are further provided to constitute a gaming machine.

  FIG. 2 is a partial enlarged view for explaining a joint portion (A portion in FIG. 1) between the bottom plate 21 and the right side plate 24 of the cabinet 1. Since the five wall plates have the same structure, the bottom plate 21 will be described as an example. The bottom plate 21 is composed of an MDF material 3 that is a kind of wood-based plate material and a conductive sheet material 4. The conductive sheet material 4 has a two-layer structure, and is manufactured by applying a conductive paint containing fine particles of silver and copper to one side of a long paper material 41 corresponding to a base material using a printing machine. Yes. The conductive coating is dried to form a conductive coating layer 42 (indicated by hatching in FIG. 2), and has the properties of an electric conductor in the same manner as the metal foil, so that it can have a shielding function. After the conductive sheet material 4 is attached to the entire surface of one side of the MDF material 3 using an adhesive, the conductive sheet material 4 is cut into a predetermined size and subjected to perforation processing to manufacture the bottom plate 21.

  The five wall plate materials 21 to 25 that have been subjected to perforation processing are assembled into a predetermined box shape with the conductive sheet material 4 inside. At this time, at the place where the wall plate materials abut each other, the conductive coating layers 42 come into contact with each other as shown in part B of FIG. Eventually, the conductive coating layers 42 of all the five wall plate members 21 to 25 become conductive and function as an electric shield layer. Even if some conduction is uncertain, a shielding effect is produced, but it is certain if a conduction means is provided. As the conduction means, the conductive paint layer 42 may be overcoated at a location where the conductive coating layers 42 are in contact with each other.

  In the present invention, a conductive sheet material composed of a sheet-like base material and a conductive coating layer is pasted on a wall plate material forming a cabinet. For example, the electronic control unit disposed inside the cabinet is electrically conductive. Various applications are possible, such as pasting a sheet material to provide a direct shielding function.

It is a figure explaining the cabinet of the game machine of the Example of this invention. In the Example of FIG. 1, it is the elements on larger scale explaining the coupling | bond part of the baseplate and right side board of a cabinet.
