Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pachinko machine.
[0002]
[Prior art]
Many pachinko machines are made of a synthetic resin that is lightweight and resistant to corrosion. However, since the synthetic resin has a property that the dielectric constant is low and the static electricity tends to accumulate, the control device that controls the operation content adjacent to the synthetic resin gaming member may malfunction due to the accumulated static electricity. There is a risk of it happening. Therefore, in the conventional pachinko machines, in order to prevent the accumulation of static electricity, game members such as mechanism plates, game ball tanks, and lower dishes, which are likely to accumulate static electricity, contain antistatic agents and conductive materials. Some are made of synthetic resin, and are configured so that a ground wire is drawn out from these game members and discharged to a metal outside the machine base.
[0003]
[Problems to be solved by the invention]
However, as described above, a pachinko machine provided with a ground wire on a predetermined game member cannot sufficiently discharge and remove the accumulated static electricity, and the control device may malfunction. In addition, some pachinko machines are configured such that a mechanism plate is formed by connecting a plurality of members from the viewpoint of ease of assembly at the time of manufacture. In particular, static electricity tends to accumulate at the connecting portions of each member, and even if a ground wire is provided, static electricity cannot be effectively removed. Therefore, the control device malfunctions frequently.
[0004]
The object of the present invention is to solve the problems of the conventional pachinko machine and to have excellent performance for preventing static electricity retention (hereinafter referred to as static electricity retention prevention performance), and malfunction of the control device due to the accumulated static electricity. It is to provide a pachinko machine that does not cause any problems.

Further, when the upper plate 13 is filled with game balls, the overflowing game balls flow down to the lower plate 14.
[0014]
In the pachinko machine 1, as described above, at least a part of the game member is a synthetic resin containing an antistatic agent or a conductive material (that is, polycarbonate filled with carbon black, ABS resin containing ferrite, cationic surface activity (ABS resin containing an agent, ABS resin filled with carbon fiber). At least a part of the resin is placed in contact with the metal middle frame 2. For this reason, static electricity efficiently flows from a synthetic resin game member containing these antistatic agents or conductive materials to a metal middle frame and flows to the outside of the machine base, so it has excellent static electricity retention prevention performance, Troubles caused by accumulated static electricity are unlikely to occur.
[0015]
Further, in the pachinko machine 1, the game ball tank 4 has an iron plate 28 attached thereto, and the game ball tank 4 is installed in the middle frame 2 with the iron plate 28 in contact with the middle frame 2. Static electricity hardly accumulates at the connecting portion between the middle frame 2 and the middle frame 2, and troubles caused by static electricity accumulated at the connecting portion between the game ball tank 4 and the middle frame 2 are less likely to occur.
[0016]
Further, in the pachinko machine 1, the game ball tank 4, the mechanism plate 3, and the lower plate 14 in which static electricity is likely to stay are formed of a synthetic resin containing an antistatic agent or a conductive material, and at least a part thereof is middle. Since it is installed in contact with the frame 2, it has a very high antistatic property and prevents troubles caused by the accumulated static electricity.
[0017]
On the other hand, the pachinko machine 1 has a conductive layer 20 made of a conductive paint interposed in at least a part of the connecting portion between the first member 5 and the second member 6 of the mechanism plate 3, so that the mechanism is Although the plate 3 is easy to assemble, static electricity does not easily accumulate in the connection portion of the mechanism plate 3, and troubles caused by static electricity accumulated in the connection portion of the mechanism plate 3 do not easily occur.
[0018]
In addition, in the pachinko machine 1, since the mechanism plate 3 has an insulating layer 23 made of an insulating material interposed in an installation portion of the relay substrate 22, static electricity staying on the mechanism plate 3 flows to the relay substrate 22. Trouble caused by is difficult to occur.
[0019]
The configuration of the pachinko machine of the present invention is not limited to the aspect of the above embodiment, and includes an outer frame, a middle frame, a mechanism plate, a game ball tank, an upper plate, a lower plate, a conductive layer, an insulating layer, and the like. The configuration of the shape, structure, etc. can be changed as needed.
[0020]
For example, a pachinko machine is not limited to a game ball tank, mechanism plate, or lower plate formed of a synthetic resin containing an antistatic agent or a conductive material, but other members such as an upper plate and a front frame Alternatively, a synthetic resin containing an antistatic agent / conductive material may be used. As described above, the game ball tank, the mechanism plate, and the lower plate are members that are particularly prone to accumulate static electricity. Therefore, when only these members are formed of a synthetic resin containing an antistatic agent / conductive material, Although the pachinko machine can be manufactured at low cost, it is excellent in static electricity retention prevention performance. The game members are not limited to those integrally formed by injection molding using a synthetic resin containing an antistatic agent / conductive material, and only a part thereof contains the antistatic agent / conductive material. It may be formed of a synthetic resin, or a coating made of a synthetic resin containing an antistatic agent / conductive material on the surface. Further, the method for preventing the static electricity from staying at the contact portion between the game member and the middle frame is not limited to the method of attaching the iron plate to the game member as in the above embodiment, and the contact portion between the game member and the middle frame A part formed of a synthetic resin containing a conductive material is attached (for example, a polyolefin seal containing a conductive material is attached), and the gaming member is brought into contact with the middle frame via the part (contact The gaming member is installed in the middle frame), and the game member is attached to the middle frame by applying a conductive paint to the contact portion of the gaming member with the middle frame and bringing the coated portion into contact with the middle frame. A method of installation may be used. Even when such a configuration is employed, static electricity can be effectively prevented from staying at the contact portion between the gaming member and the middle frame.
[0021]
On the other hand, the mechanism plate is not limited to one formed by connecting two members, and may be formed by connecting three or more members. In addition, as in the above-described embodiment, it is not limited to those in which a conductive paint is interposed in the connection part between the member and the member, and the connection part between the member and the member has high conductivity such as copper, iron, gold or the like. It may be a metal plate or a metal foil sandwiched between them. Even when such a configuration is adopted, similarly to the above embodiment, the pachinko machine is less likely to accumulate static electricity at the connection portion of the mechanism plate and less likely to cause trouble due to static electricity remaining at the connection portion of the mechanism plate. .
[0022]
Further, the middle frame is not limited to one formed entirely of metal, but may be formed partially from synthetic resin or the like. In the case of using a middle frame partly formed of a synthetic resin or the like, the gaming member formed of a synthetic resin containing an antistatic agent / conductive material is in contact with the metal part of the middle frame. It is necessary to install.
[0023]
【The invention's effect】
In the pachinko machine of the present invention, a metal plate and / or a conductive material is interposed in at least a part of a connecting portion of each component of the mechanism plate, so that the assembly of the mechanism plate is easy at the time of manufacture. Regardless of this, static electricity is unlikely to accumulate in the connecting portion of the mechanism plate, and troubles caused by static electricity remaining in the connecting portion of the mechanism plate are unlikely to occur.
In addition, each part of the mechanism plate is made of a synthetic material containing a conductive material or an antistatic agent, and a part of the mechanism plate is placed in contact with the middle frame. Static electricity efficiently flows into the middle frame made of the product and flows to the outside of the machine base, so it has excellent antistatic retention performance, and troubles caused by accumulated static electricity are unlikely to occur.
Furthermore, since a metal plate and / or a conductive material is also interposed between the fitting portion and the fitting protrusion, that is, the connecting portion between the middle frame and the game ball tank, static electricity hardly accumulates in the connecting portion, Troubles caused by static electricity staying at the connection between the middle frame and the game ball tank are unlikely to occur.
