DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a pachinko ball storage box used in a game arcade.

[0002]

2. Description of the Related Art Conventionally, a player stores pachinko balls in a pachinko ball storage box and places them on a stainless steel table in front of a pachinko game machine.

However, since the box containing pachinko balls is a transparent box (500 g) made of plastic (polycarbonate) and is a defective conductor, there are numerous pachinko balls (5.4 g / piece × 3000).
When the transparent box is filled in the transparent box, it is charged with static electricity and does not conduct. Therefore, there is a problem in that touching the pachinko ball and the housing box gives an electric shock to the human body and gives a sense of fear to the customer.

Therefore, there has been proposed a method in which two or four concave holes are provided in the bottom of the pachinko ball storage box for pachinko balls to enter, and the pachinko balls in the holes contact a stainless steel stand in front of the pachinko game machine and discharge. However, when the pachinko balls are rapidly filled, the discharge is insufficient and the discomfort caused by electric shock cannot be eliminated. In addition, although the idea of molding the entire pachinko ball storage box with conductive plastics was devised, the conductive plastics are opaque, so the appearance is poor and the stored balls cannot be seen from the side, so the player can enjoy a sense of superiority. Can't do it and doesn't fit into the fancy interior decoration.

BEST MODE FOR CARRYING OUT THE INVENTION A pachinko ball storage box 1 is placed on a stainless steel stand 2b provided at a front part of a pachinko game machine, and a pachinko ball 3 filled in a ball holder of the game machine is filled on the stainless steel stand 2b. Transfer to the pachinko ball storage box 1
The storage box 1 is sequentially filled.

[0008] The shining state of the filled ball 3 is observed from the side of the storage box 1 and adapts to the splendid atmosphere in the store.

Even if the user touches the storage box 1 filled with the pachinko balls 3 or the pachinko balls 3, the player can enjoy the game comfortably without electric shock and without fear of electric shock.

This is because the stored pachinko ball 3 has a static electricity (20
To 30 kv), but the static electricity is discharged to the stainless steel table 2b where the housing box 1 is placed via the conductive synthetic resins 2 'and 2 "on the upper and lower surfaces of the bottom plate 4, and the charge is eliminated. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A transparent container 1 made of an injection-molded synthetic resin made of polycarbonate resin is rectangular, and the side surface 1 'is formed by an inverted quadrangular pyramid. The area of the upper end opening is large and the area of the bottom plate 4 is small. A flange 6 is provided on the outer periphery of the upper end opening,
Handles 7, 7 integrally formed with the flange 6 are provided at both ends in the longitudinal direction.

Approximately ten through-holes 5 are formed in the bottom plate 4 at four corners and an inner peripheral edge, and a plate-shaped conductive synthetic resin 2 ′ (1.5 mm thick) having substantially the same dimensions as the bottom plate 4 is formed on the upper surface thereof. ), And a rectangular annular conductive synthetic resin 2 ″ as shown in FIG. 1 is arranged on the outer periphery of the lower surface of the bottom plate 4, and the upper surface of the conductive synthetic resin 2 ″ is positioned at a position corresponding to the through hole 5. A projection 8 to be inserted into the through hole 5 is formed, and the upper end is brought into contact with the conductive synthetic resin 2 ′ on the upper surface. The upper and lower conductive synthetic resins 2 ′,
2 "is integrally welded by ultrasonic welding at a position corresponding to the through hole 5 (FIGS. 2 and 3).

Instead of the ultrasonic welding method, as shown in FIG. 4, a mold 9 is fitted to the outer peripheral surface of the bottom of the housing box 1, and the molten conductive synthetic resin is injected and cooled from the opening to cool the upper and lower parts. The conductive synthetic resin plates 2 ′ and 2 ″ can be integrally formed through the through holes 5 and then released to expose the lower portion of the storage box 1.

When the lower end 1 "of the side plate 1 'projects below the lower surface of the bottom plate 4 as shown in FIGS. 2 to 4, the conductive synthetic resin 2" below the lower end 1 "of the side plate 1'. The lower surface is slightly (0.5 mm) projecting downward (0.5 mm) so that the lower surface contacts the surface of the stainless steel table 2b to support the pachinko ball storage box 1 on the surface of the same table 2b, and the lower surface forms a support surface 2a. You.

The conductor 2 is made of a synthetic resin such as PP, P
A mixture of E, Ps, ABS, PC, acrylic, or the like, and a conductive material such as graphite, carbon, Al powder, Fe powder, Cu powder, or the like can be used. When graphite was used as the conductive material, the electric resistance was remarkably reduced when about 20 parts by weight of the conductive material was mixed with about 80 parts by weight of the synthetic resin, and a conductive effect was recognized. That is, the surface resistivity of the conductor 2 is preferably set to 10 ⁸ Ω or less, more preferably 10 ⁶ Ω or less. The development of conductivity results from the formation of an electric path by contact between conductive particles dispersed in a resin.

The conductive synthetic resin 2 ′, 2 ″ above and below the bottom plate 4.
In other words, in addition to ultrasonic welding at the position of the through hole 5, it is possible to conduct electricity by bonding, caulking, or the like in addition to integration by spot welding (thermal fusion) or vibration welding.

The synthetic resin molded container 1 that is easily charged with static electricity is effective for the above-mentioned pachinko ball storage box, various OA equipment component boxes, home electric appliance component boxes, electronic component boxes, and the like. It can be used.
