When the mechanism plate 12 is opened, the pachinko ball of the ball guide gutter 66 is first stopped by rotating the ball stopper member 81 from the chain line state to the solid line state in FIG. By removing it from 69, the mechanism plate 12
Can be opened without the ball spilling. At this time, since the supply path of the pachinko balls such as the ball tank 65 and the ball guiding gutter 66 is provided in the front frame 3, the mechanism plate 12 does not tilt due to the ball weight of the pachinko balls, and the opening / closing operation becomes light. At the time of closing, the fixing tool 25 can be surely fitted and fixed to the locking portion 69 without displacement. In addition, since the front frame 3 is divided and formed, not only is inventory management and transportation convenient, but also the size of the mold for molding the front frame 3 is reduced, so that the manufacturing cost is reduced. Attachment of the hinge fittings 3a, 3b, etc. is simplified, and work efficiency is improved.

In the present embodiment, the front frame 3 is
Although it is divided and formed, it may be integrally formed in a frame shape as vertical and horizontal divided formation. Furthermore, even if the mounting frame portion of the game board 11 is formed as a separate body, the material of the front frame 3 is not limited to the above-mentioned one, and may be a material using wood or waste paper which has conventionally been used in many cases. Also, a ball tank 6 as a supply path for pachinko balls.
A part or the whole of the ball 5 and the ball guiding gutter 66 may be formed integrally with the front frame 3.

Further, as shown in FIG.
8 and the ball dispensing device 19 may be provided on the front frame 3 side, and by providing the ball dispensing device 19 on the front frame 3 side, the load on the mechanism plate 12 is reduced and the opening and closing is smoother, and the ball dispensing device 19 is provided. The device 19 can be used as ball stopping means, and it is not necessary to separately provide a ball stopping means. Also, the mechanism plate 12 also has only a passage portion such as the ball discharge gutter 20, and the opening of the ball discharge gutter 20 at the connection between the ball dispensing device 19 and the mechanism plate 12 may be enlarged, and the precision at the connection portion may be increased. Is not required, the size of the mold of the mechanism plate 12 can be reduced, and the cost can be reduced.

Further, for example, the upper frame 26 and the left and right frame 2
At the time of assembling the pieces 8 and 29, they are fastened together by using mounting screws of the ball tank 65 and the ball guiding gutter 66, or the lower frame 27
When assembling the left and right side frame portions 28 and 29, the firing device 4
It is preferable to use the mounting screws of the hinge 4 and the hinge 43 to fasten together. At this time, the static electricity of the firing device 44 and the static electricity of the upper ball receiving tray 6 attached to the glass door frame 5 and the front plate 7 are removed via the hinges 43 using the left and right side frame portions 28 and 29, and furthermore, By attaching the ball tank 65 and the ball guiding gutter 66 via a conductive member such as an iron plate, static electricity charged on the pachinko ball can be removed.

FIGS. 16 to 18 show an embodiment in which the entire front frame is provided with a conductive function, and the same components as those in the above embodiment will be described with the same reference numerals. 16 and 17, a conductive resin J1 obtained by mixing a conductive material such as carbon or stainless steel or other metal fine powder or fiber (preferably a coil) with synthetic resin such as ABS to impart conductivity.
Is a core material, and a skin material is a non-conductive resin J2 such as ABS.
As shown in FIG. 16, a front frame 3 is provided with a resin flow channel 90 near a ball tank 65 and a mounting boss 68 of a ball guiding gutter 66 as a supply path for pachinko balls as shown in FIG. To ensure that the conductive resin J1 turns around the mounting boss 68,
It is as if the wiring is laid all over the front frame 3. As shown in FIG. 17, the hinge fittings 3a and 3b connected to the machine casing 2 are fixed by screws 91 serving as conductive fasteners, and are electrically connected to the core material of the conductive resin J1 via the screws 91. And the hinge fittings are discharged through 3a and 3b. The conductive material includes a simple substance or an alloy of copper, iron, nickel, platinum, gold, silver, aluminum, or the like.

The ball tank 65 and the ball guiding gutter 66 as a supply path of the pachinko ball are formed of a conductive resin J1 as a conductive function, and a screw 91 as a conductive fastener is provided.
By screwing the mounting piece 74 to the mounting boss 68, the screw 91 is screwed into the conductive resin J1 of the core material, and the ball tank 65 and the ball guide gutter 66 are fixed to the front frame 3 in a conductive state. . Preferably, it is molded by sandwich molding using the conductive resin J1 as a skin material, and the strength is increased by providing a resin flow channel 90 so as not to hinder the flow of the pachinko ball particularly at the ends and corners that are easily impacted, The entire ball tank 65 and the ball guiding gutter 66 can be made tough and inexpensive as compared with the case where only the conductive resin J1 is used.

As shown in the above embodiment, the front frame 3 is divided and the left and right side frame portions 28, 29 are formed by die-casting of an aluminum alloy and assembled with a conductive fastener. Although the entire front frame 3 may have conductivity, it goes without saying that the entire front frame 3 may be integrally formed by sandwich molding or multiple molding.

As described above, by imparting conductivity to the entire front frame 3, static electricity generated and discharged due to the flow of the pachinko balls or the like is conducted to the front frame 3 by the conductive fastener 91, and is transmitted through the hinge mechanism 4. The pachinko ball is in a non-static state. For this reason, even if the player touches the pachinko balls stored in the upper ball tray 6, no electric shock is caused, and a situation that gives the player uncomfortable feeling can be eliminated. In addition, the instantaneous application of static electricity prevents the high voltage from flowing to the wiring board and the electronic circuit board, thereby preventing malfunction of the electronic device.

It should be noted that a conductive plate or the like may be separately provided on the ball tank 65 and the ball guiding gutter 66 as a conductive function so that conduction is made via the conductive plate. Also, a part or all of the front and rear left and right side walls and the bottom wall of the ball tank 65 and the ball guiding gutter 66 may be formed of metal to have a conductive function.

When the front frame 3 is formed by sandwich molding, the core material is made of the conductive resin J1 and the skin material is made of the nonconductive resin J2 such as ABS, so that the mixing ratio of the conductive resin which is high in material cost is increased. As a low mixing ratio of about 30%, the amount of use can be greatly reduced, and the manufacturing cost can be reduced. In addition, since the conductive resin J1 having a low impact strength can be covered with the non-conductive resin J2 such as ABS having a high impact strength, the front frame 3 made of only the conductive resin J1 can be covered.
Thus, the impact strength can be improved. Therefore, the impact strength of the entire front frame 3 can be improved, and the roots of the bosses and ribs provided on the front frame 3 can be reinforced. Even in this case, damage can be prevented. Further, when the core material of the front frame 3 is made of the conductive resin J1, if the screw 91 as the conductive fastener is of a length near the base of the boss 68, the molding condition is slightly varied, Even if the conductive resin does not turn all the way up to the opening end of the screw hole of the boss 68, it is possible to ensure conduction.

Further, when the front frame 3 is formed by multiple molding of the conductive resin J1 and the non-conductive resin J2, as shown in FIG.
By molding the ball guiding gutter 66 with the conductive resin J1, it is possible to conduct with each other by attaching them in a contact state without using a conductive fastener and a conductive fastener. At this time, since the conductive resin is of a gray-black type, the non-conductive resin J on the front surface, which is particularly visible to the player,
2 may look dull due to the conductive resin,
By interposing a white resin between the non-conductive resin J2 and the conductive resin J1, the appearance can be improved without dulling the surface color. In addition, it is preferable to use a resin having good fluidity to reduce the thickness because the thickness is inevitably increased in the case of a three-layer structure, but there is a possibility that peeling may occur due to the material of the white resin of the intermediate layer, ABS
It is preferable to use a polyamide having good compatibility with polypropylene, or to use a polypropylene having low compatibility with an additive for increasing compatibility. Further, instead of the white resin, a white film may be formed by filling the first layer, inserting the film, and then filling the second layer again.

As described above, at least the surface is formed of a synthetic resin having conductivity, and a relatively large member such as the front frame 3 is formed of a conductive resin. Is obtained.

Also, by providing the entire front frame 3 with conductivity, it is possible to conduct the glass door frame 5 mounted on the front frame 3, the upper and lower ball receiving trays 6, 8 and the game board 11. The entire static electricity can be eliminated. Further, the winning ball collecting cover 14 and the substrate box 17 are provided with conductivity, and are provided in contact with the front frame 3 and the contact pieces to form the winning ball and the substrate box 1.
7 can also be removed. Also, the support plate 3
By providing the cover 34 having a shape that covers substantially the entire surface of the device 1 with conductivity, static electricity can be removed through the cover 34 in contact with the out ball and the winning ball. In particular, it is preferable that the winning ball collecting cover 14, the substrate box 17 and the cover body 34 are formed of a resin mixed with stainless steel fiber and have conductivity.

Further, by forming the machine frame 2 by sandwich molding using the conductive resin J1 as a core material, or by forming at least the surface of the machine frame 2 as the conductive resin J1, multiple molding is performed through the hinge mechanism 4 without using a ground wire. The static electricity of the pachinko gaming machine 1 can be grounded to the installation island.

I can guide you.

Further, by providing the front frame with a conductive function, the static electricity of the pachinko balls in the supply path can be removed, and it is possible to prevent the player from feeling uncomfortable or to prevent the board from being adversely affected.
