Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a pachinko machine,
More specifically, the present invention relates to an earthing mechanism provided in a pachinko machine.

[0002]

2. Description of the Related Art In a so-called pachinko machine, parts and members made of an insulator such as a synthetic resin, that is, parts and members that are easily charged, are frequently used. Pachinko balls or the like may rub on the surface of such parts. Alternatively, static electricity is generated in the parts / members due to contact (collision) or the like. On the other hand, with the recent increase in complexity and diversification of pachinko games, pachinko machines themselves have been highly electronically equipped. Therefore, the electronic components mounted on the pachinko machine may be damaged or malfunction in the control circuit due to the static electricity generated by the parts / members (hereinafter referred to as “static electricity generating parts”) made of an insulator such as synthetic resin which is easily charged. It is important to take some countermeasures against static electricity in the pachinko machine in order to prevent the occurrence.

As one means for achieving this, a pachinko machine may be provided with a grounding mechanism for preventing the static electricity generating section from being charged with static electricity. For example, JP-A-61-2937
No. 7 and JP-A-8-32004 disclose a general lead wire or a metal plate attached to a ball passage (that is, a tank rail extending from a ball storage tank) provided on the back of a pachinko machine. Alternatively, it is disclosed that one end of a metal plate is connected to a conductive portion (hereinafter referred to as a “conductor portion”) of a pachinko machine and grounded.

[0004]

Incidentally, the static electricity generating portion in the pachinko machine is not limited to a part on the back side of the pachinko machine such as the above-mentioned ball storage tank and the ball passage, but is made of an insulating material such as synthetic resin. Any part that can contact and friction with a pachinko ball or the like can be a static electricity generating part. For example, various prize devices mounted on the game board on the front side of the pachinko machine, or pachinko balls (prize balls) provided on the front side of the pachinko machine
Any of the synthetic resin members such as the trays described above can be static electricity generating parts. Therefore, in order to completely prevent the electronic components mounted on the pachinko machine from being damaged or malfunctioning due to static electricity, not only the above-mentioned ball storage tank and the ball passage, but also the grounding of the static electricity generating section on the front side of the pachinko machine. It is desirable to apply. This is because electronic components such as a proximity switch are also mounted on various winning devices mounted on the game board, and it is necessary to prevent erroneous operation of these components due to static electricity.

[0005] However, the construction of a grounding mechanism using a general lead wire or metal plate as described in the above-mentioned publication limits the portion applied to the pachinko machine main body.
For example, in the current configuration of a pachinko machine, a prize-winning device or the like (static electricity generating portion) on the front side of the pachinko machine (for example, in a game board surface requiring hermeticity) and the conductor portion of the pachinko machine main body are directly connected to a lead wire or metal. It is difficult to electrically connect using a plate. In the case of grounding each of a plurality of static electricity generating units arranged separately in a pachinko machine, depending on the above-mentioned conventional metal plate, metal plates are individually attached to the plurality of static electricity generating units, and these are individually attached. Need to be grounded. That is, it is necessary to separately attach metal plates to a plurality of static electricity generating portions, connect each metal plate to a conductor portion of the pachinko machine body by a lead wire or the like, and individually ground them. Was. Therefore, depending on the conventional ground mechanism made of a lead wire or a metal plate, the structure of the pachinko machine has to be complicated or a significant design change has to be made.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a pachinko machine capable of realizing grounding at a plurality of static electricity generating parts at once with a simple structure. That is.

Alternatively, one static electricity conduction path composed of the conductor portion is formed. Therefore, according to the first pachinko machine of the present invention, the grounding process is not performed for each static electricity generating unit as in the conventional ground mechanism, and any one of the static electricity conducting paths formed by using the conductive sheet is used. By performing the grounding process at one portion, the static electricity can be removed from all of the static electricity generating portions at the plurality of locations constituting the static electricity conduction path at once.

The present invention is also the first pachinko machine of the present invention, wherein the conductive sheet is disposed between the static electricity generating section and / or the conductor section and the pachinko machine main body. (Hereinafter referred to as “the second pachinko machine of the present invention”).

In the second pachinko machine of the present invention, the conductive sheet is interposed between the static electricity generating section and / or the conductor section and the pachinko machine main body, thereby making accurate and delicate positioning without performing the positioning. The conductive sheet can be easily attached to the pachinko machine main body, and it is not necessary to separately secure a space for attaching the conductive sheet to the pachinko machine as when a conventional metal plate or lead wire is provided. For this reason, according to the second pachinko machine of the present invention,
There is no need to change the existing shape of the pachinko machine or the arrangement and configuration of parts, and grounding from a plurality of static electricity generating parts can be realized at once while maintaining the appearance of the entire pachinko machine.

Further, the present invention is the first or second pachinko machine of the present invention, wherein the pachinko machine has a static electricity generating portion or a conductor portion disposed on the front side and a pachinko machine disposed on the back side. Pachinko machine (hereinafter referred to as "third pachinko machine of the present invention") in which a static electricity generating portion or a conductive portion is electrically connected by the conductive sheet.
I will provide a.

In the third pachinko machine of the present invention, the static electricity generating portion or the conductor portion disposed on the front side of the pachinko machine and the static electricity generating portion or the conductor portion disposed on the back side of the pachinko machine are formed of the conductive sheet. Electrically connected by
That is, in the third pachinko machine of the present invention, the static electricity generated in the static electricity generating portion on the front side of the pachinko machine can be conducted to the back side of the pachinko machine via the conductive sheet. For this reason, according to the third pachinko machine of the present invention, the static electricity generated in the static electricity generating section on the pachinko machine front side is not provided without providing a grounding wire on the pachinko machine front side that impairs the beauty of the entire pachinko machine. It can be efficiently removed from the back side of the pachinko machine.

As shown in FIGS. 1 and 2, this pachinko machine 1 is formed in a frame shape on a hinge portion 3a of a wooden frame 3 formed in a rectangular frame shape, like a general conventional pachinko machine. The front frame 2 is constructed by being pivotally mounted so as to be openable and closable. Below the front frame 2, a filling plate 4 for filling a gap between the front frame 2 and the wooden frame 3 is fitted. A rectangular opening is formed in the center of the front frame 2, and a metal edge member 6 is screwed to a peripheral edge of the opening to reinforce the opening. Thus, the metal frame 11 and the front plate 1 are provided in the opening (that is, the inner edge of the edge member 6).

For this reason, static electricity is easily generated and charged in the portion due to friction or collision with the pachinko balls released from the upper plate opening 12a to the upper plate 7. Therefore, these members arranged on the front side of the pachinko machine 1 correspond to static electricity generating units in the pachinko machine 1. In addition, each member which comprises this pachinko machine 1 mentioned above
The components are the same as those provided in a general pachinko machine and do not characterize the present invention, and therefore, detailed description thereof will be omitted.

On the other hand, as shown in FIG. 2A, a metal locking member 16 for locking the front frame 2 to the wooden frame 3 so as to be lockable is provided at the open end of the back surface of the front frame 2. Is installed.
The lock member 16 has a pair of upper and lower hook pieces 16a, 16b.

A part of 6 extends and extends to the front surface of the front frame 2 to form a keyhole 17. As a result, the keyhole 1
7 can be locked by inserting a predetermined key (not shown). That is, when the front frame 2 is closed to the wooden frame 3, the pair of hook pieces 16 a and 16 b are engaged with engaging openings (not shown) provided at corresponding locations on the wooden frame 3 side, The closing and locking of the front frame 2 are simultaneously achieved (FIG. 2B). Then, by inserting a predetermined key into the keyhole 17 and sliding the pair of hook pieces 16a, 16b, the engagement between the hook pieces 16a, 16b and the wooden frame 3 (the above-mentioned engaging opening) is released. Thus, the front frame 2 can be opened again. The hook pieces 16a,
The structure itself of the locking mechanism consisting of 16b and the engagement opening may be the same as that provided in a general pachinko machine, and is not particularly related to the implementation of the present invention, and therefore detailed description is omitted.

As shown in FIG. 2B, the pachinko machine 1
A game board 14 constituting a game area 14a (that is, an area where nails, windmills and the like (not shown) are appropriately arranged; see FIG. 1) of the pachinko machine 1 is mounted at a substantially central portion on the back side. As shown in FIG. 1, on the surface of the game board 14,
As in the case of a general conventional pachinko machine, a launch ball guiding rail 21 for guiding a pachinko ball fired from a launching device (not shown) of the pachinko machine to the upper part of the game board 14 is mounted in a circular spiral shape. Have been. The inner area surrounded by the launch ball guiding rail 21 corresponds to a game area 14a in the present game board 14. A plurality of mounting holes (not shown) for mounting various game machines are formed in the game area 14a. Thus, as shown in FIG. 1, the normal winning device 23 that forms the normal winning opening 23a, the large winning device that includes the variable winning opening 24a that opens and closes according to the pachinko gaming situation, and a plurality of normal winning openings 24c ( 24 and the like are inserted and mounted in the mounting holes, respectively. The gaming board 14 is usually equipped with a game device such as a symbol display device or a decorative indicator lamp in addition to the normal winning device 23 and the large winning device 24 shown in FIG. Is not shown because it is not particularly necessary.

By the way, the ordinary winning device 23, the large winning device 24 itself, and the path of the pachinko ball formed inside the winning devices 23 and 24 (hereinafter referred to as "winning ball passage") are mainly made of synthetic resin or the like. It is formed of an insulator (nonconductor). For this reason, static electricity is easily generated and charged in the winning devices 23 and 24 due to friction and collision with the pachinko balls passing through the game area 14a and the pachinko balls winning the winning ports 23a, 24a and 24c. Therefore,
These prize devices 23 and 24 arranged on the game board 14 (game area 14a) and other game devices (so-called official items) similarly formed mainly of an insulator such as a synthetic resin,
It corresponds to a static electricity generating unit in the pachinko machine 1. This will be described in detail with reference to FIG. 10 using the large winning device (attacker) 24 as an example. As shown in FIG. 10, the large prize winning device 24 is a synthetic resin molded into a flat plate shape corresponding to a pedestal equipped with various structures, similarly to other general roles provided on the game board 14. The base 25 is made as a base. An appropriate number of screw holes are provided in the peripheral portion of the base 25, and a part of the holes is inserted into mounting holes provided in the game board 8 in advance so that the game board 8 can be inserted.
Screwed to the surface (see FIG. 1). The base 25 is usually plated for the purpose of improving decorativeness and the like, and has a decorative seal 2 made of a resin film on its surface.
9 is affixed. On the front side of the base 25, the variable winning opening 24a and the normal winning opening 24c are provided, and a decorative cover member 28 made of synthetic resin is mounted.
Inside the decorative cover member 28, a lamp and a lamp board (not shown) are provided. In addition, the floating winning opening 24
A switch 26a (typically, an electromagnetic proximity switch, a mechanical contact switch, or the like) for detecting a winning of a game ball is provided in a prize ball passage inside (a V zone, for example) or inside the normal prize port 24b. I have. On the other hand, on the back side of the base 25, a switch terminal 26b connected to the ball detection switch 26a, and a pachinko machine 1 main body for controlling opening and closing of the variable winning opening 24a and other various operations in the real winning device 24. Substrates 27a for transmitting and receiving electric signals,
27b is mounted.

As described above, the large prize winning device 24 illustrated in FIG. 10 and other general accessories are often made of an insulator such as a synthetic resin capable of easily generating static electricity by the collision or contact of a pachinko ball on the surface thereof. On the other hand, the ball detection switch 26a (switch terminal 26
b) and many electronic components such as the boards 27a and 27b are also mounted. That is, static electricity generated in the seal 29 on the surface of the large winning device 24 (gear) and the winning ball passages inside the various winning openings 24a and 24c due to the collision or contact of the pachinko balls is applied to the plated portion of the base 25 (ie )
Through the electronic component, which may cause a malfunction. In addition, the conduction of the static electricity generated by the collision or contact of the pachinko balls to the electronic components can occur even if the surface of the base 25 is not plated. Therefore, it is important to take countermeasures against static electricity of the large prize device 24 and other accessories (especially those on which a large amount of synthetic resin is used on the surface and a large number of electronic components are mounted) mounted on the game board 14. It is one aspect of the problem to be solved by the present invention to perform effective grounding (that is, electrostatic treatment) on these attached accessories.

On the other hand, on the back side of the game board 14 (that is, on the back side of the pachinko machine 1), a board storage case 20 typically made of synthetic resin is provided. Inside the board storage case 20, a circuit for controlling the various gaming machines provided on the gaming board 14 (for example, controlling the display of a symbol display device (not shown) and controlling the opening and closing of the variable winning opening 24a). The board is mounted, and constitutes a main control unit in the pachinko machine 1. In addition, on the side of the game board 14, various devices required for performing a pachinko game, such as a prize ball storage tank 18 and a prize ball payout device 19, are provided. The ball passages in the prize ball storage tank 18 and the prize ball payout device 19 are usually formed of an insulator (non-conductor) such as a synthetic resin. For this reason, static electricity is easily generated and charged due to friction or collision with the pachinko ball flowing at the location. Therefore, these devices arranged on the back of the pachinko machine 1 correspond to the static electricity generating section of the pachinko machine 1.

Hereinafter, the features of the grounding mechanism of the present invention provided in the pachinko machine 1 will be described with reference to the drawings. FIG. 3 is a partially cutaway rear view of the game board 14 in the pachinko machine 1. 4 and 5 are a sectional view taken along line AA and a sectional view taken along line BB of FIG. 3, respectively.

As shown in FIGS. 1 and 3, the normal prize device 23 and the large prize device 24 are partially inserted into the mounting holes provided in the game board 14 in advance (hereinafter, a part to be inserted is simply inserted). Parts 23b, 24b) are inserted and fixed by screws v on the front side of the game board 14. As described above, in the present embodiment, the outer wall of the insertion portion 24b (that is, a part of the base 25) of the large winning device 24 is plated to have electric conductivity. Therefore, the insertion portion 24 of the large winning device 24
The outer wall b corresponds to a conductor portion in the pachinko machine 1.
Here, as shown in FIG. 3 and FIG. 4, in the present embodiment, the conductive sheet 30 is sandwiched and mounted in a gap between the mounting hole of the game board 14 and the insertion portion 23b of the normal winning device 23. Both ends of the conductive sheet 30 are exposed on the front side and the back side of the game board 14, respectively. In addition, the conductive sheet 30 according to the present embodiment is a thin tape-shaped flexible mesh sheet in which a thin copper wire forms a so-called mesh (mesh), and is used for the pachinko machine 1 (here, the game board 14). It can be closely attached to the surface along the shape.

As shown in FIG. 4, one end of the conductive sheet 30 interposed therebetween (the back side of the game board 14).
Is a mounting hole of the game board 14 and a large winning device 24 insertion portion 24
It is also sandwiched in the gap with b and is sent out to the front side of the game board 14 again. Then, both ends of the conductive sheet 30 arranged in this way are screws v for fixing the ordinary winning device 23 and the large winning device 24, respectively.
To the game board 14. At this time, as described above, since the conductive sheet 30 according to the present embodiment has a mesh shape, the screw v can be made to penetrate at any position. For this reason, in the present conductive sheet 30, there is no need to separately provide a hole for screwing, and further, it is not necessary to perform positioning at the time of attachment. Therefore, as shown in FIG. 4, the conductive sheet 30 can be easily placed on the game board 14 together with the prize devices 23 and 24 while being sandwiched under the screw mounting portions of the normal prize device 23 and the large prize device 24. Screws can be worn.

As described above, as a result of connecting the ordinary winning device 23 and the large winning device 24 with the conductive sheet 30, the ordinary winning device 23 and the large winning device 24 become one static electricity via the conductive sheet 30. As a result, static electricity generated in the normal winning device 23 due to friction and collision of the pachinko balls inside and outside the normal winning opening 23a is transferred from the normal winning device 23 (typically, a plated portion) to the conductive sheet 30. (In this embodiment, the conductor may include a screw v) to be transmitted to the insertion portion 24b (that is, the plated outer wall portion) of the large winning device 24.

Further, in the present embodiment, as shown in FIGS. 3 and 5, the conductive sheet is provided in the gap between the mounting hole of the game board 14 and the insertion portion 24b of the large prize winning device 24 also in the lower portion of the large prize winning device 24. Conductive sheet 3 similar to 30
1 is sandwiched. Like the conductive sheet 30, one end of the conductive sheet 31 is sandwiched under the screw mounting portion of the large winning device 24 on the front side of the game board 14, and the game device 14 together with the winning device 24 is held. Is screwed on. On the other hand, the other end of the conductive sheet 31 is fixed by a screw v separately provided on the back side of the game board 14 (FIG. 3). Thus, as shown in FIGS. 3 and 5, the grounding of the large winning device 24 is realized by attaching the ground wire 35 to the screw v. That is, the static electricity generated in the large winning device 24 due to friction or collision with the pachinko balls inside and outside the normal winning opening 24c and the variable winning opening 24a is transferred to the insertion portion 24b of the large winning device 24 (ie, the plated outer wall portion). ) Is transmitted to the screw v and the conductive sheet 31, and then flows off to the ground (typically, the entire game machine installation area (island) in the game hall) through the conductor v and the ground wire 35. . Here, as described above, in the present embodiment, the large prize device 24 and the normal prize device 23 above the large prize device 24 constitute an electrostatic conduction path electrically connected by the conductive sheet 30. The ordinary winning device 23
Is also transmitted to the large prize device 24 via the conductive sheet 30, and together with the static electricity generated by the large prize device 24, the conductive sheet 31 and the ground line 3.
5 can be washed off to the ground.

As described above, in the present pachinko machine 1, since the conductive sheets 30 and 31 are made of a flexible mesh member made of copper or the like, the pachinko machine 1 can be easily pachinko machine with a screw v or an adhesive. It can be directly mounted in a plane on the main body 1 (here, the game board 14).
Furthermore, since the conductive sheets 30 and 31 can be arranged by utilizing the gap between the pachinko machine 1 main body (here, the game board 14) and the static electricity generator (here, the winning devices 23 and 24), the conventional lead wire and There is no need to separately secure a space as when a metal plate is separately provided. Therefore, by using the conductive sheets 30 and 31 of the present invention, a plurality of static electricity generating units (here, the prize winning device 23) can be used without changing the existing configuration (here, the game area 14a of the game board 14). , 24, etc.) can be grounded at once. Further, according to the grounding mechanism of the present invention, since it is not necessary to arrange a lead wire or a metal plate on the front of the pachinko machine 1, the pachinko machine 1
The grounding of the accessories mounted on the game board 14 can be realized without impairing the overall appearance.

Next, the upper plate 7 mounted on the pachinko machine 1 will be described.
A grounding mechanism for grounding the front plate 12 will be described with reference to the drawings. FIG. 6 is a partial front view showing a main part of the front surface of the pachinko machine 1. FIG. 7 is a partial rear view showing a main part on the open side of the rear surface of the front frame 2. FIG.
FIG. 7 is a cross-sectional view taken along line CC in FIG. 6 (however, the front plate 12 and the wooden frame 3 are not shown in this drawing).

As shown in FIG. 6, a conductive sheet 32 similar to that described above is sandwiched between the edge member 6 and the front frame 2 at the lower end on the open side of the opening of the front frame 2. Along the opening of the front frame 2, it is attached from the front side to the back side with an adhesive. As shown in FIGS. 7 and 8, the conductive sheet 32 is sandwiched between the edge member 6 and the front frame 2 on the front side of the front frame 2 by screws v. On the other hand, on the back side of the front frame 2, the front frame 2 is fixed together with the lock member 16 by screws v while being sandwiched between the lock member 16 and the front frame 2.

By mounting the conductive sheet 32 in this manner, when the front plate 12 is closed in the opening of the front frame 2, a part (side wall portion) of the front plate 12 is connected to the conductive sheet 32. Can be contacted. As a result, the upper plate 7, the front plate 12, and the lock member 16 constitute one electrostatic conduction path via the conductive sheet 32, and as a result, the friction of the pachinko balls in the upper plate 7 and the upper plate opening 12a, etc. The generated static electricity is conducted from the side wall of the front plate 12 to the conductive sheet 32, and further conducted from the conductive sheet 32 to the lock member 16 and grounded. Here, a ground wire (not shown) is provided at the lock member 16 or at an appropriate place where the lock member 16 comes into contact (for example, a part of the wooden frame 3 in which the edge member 6 and the hook pieces 16a and 16b are accommodated), thereby forming the upper plate 7 In addition, the static electricity generated by the front plate 12 can be washed away to the ground (typically, the entire game machine installation area (island) in the game hall).

As described above, in the pachinko machine 1, the static electricity generating portion (here, the upper plate 7 and the front plate 12) on the front side of the pachinko machine 1 and the conductor portion (here, the lock member 16) on the back side of the pachinko machine 1 are provided. ) Can be electrically connected by the conductive sheet 32, and as a result, the static electricity generated on the front side of the pachinko machine 1 can be guided to the back side of the pachinko machine 1 and grounded. At this time, according to the grounding mechanism of the present invention, since the thin flexible conductive sheet 32 is used,
It is not necessary to arrange a lead wire or a metal plate that impairs aesthetic appearance on the front side of the pachinko machine 1, and furthermore, holes are formed in the front plate 12 and the front frame 2 for penetrating the lead wire or the metal plate, which are problematic for security. No need to form.

Although the preferred embodiment of the pachinko machine of the present invention has been described with reference to the drawings, in the pachinko machine of the present invention, the conductive sheet has flexibility, It is only necessary that the conductor portion is connected so as to be electrically conductive, and is not limited to the above-described embodiment. For example, the conductive sheets 30, 3 used in the above-described embodiment
A mesh-like sheet body that can be easily screwed to a pachinko machine main body without the need for positioning or the like is used as 1 and 32, but other structures can also be used. For example, a thin foil (such as a copper foil) is also suitably used as the conductive sheet in the present invention.

The conductive sheet according to the present invention can be used for grounding any of the winning devices 23 and 24 and the upper plate 7 as well as the static electricity generating portion of the pachinko machine 1. It is clear from the description of the embodiments and does not depart from the scope of the claims of the present application. For example, as schematically shown in FIG. 9 as a preferred example, a plurality of static electricity generating portions (for example, a ball tray such as the upper plate 7 or a prize ball storage tank 18) of a pachinko machine and a plurality of conductor portions (typically) are provided. Specifically, the edge members 6 and the metal parts such as the lock member 16) may be connected by lead wires 37, and the conductor parts may be electrically connected to each other by the conductive sheet 40. In this case, by providing the grounding line 36 at one position of the conductive sheet 40 or the conductive portion (metal portion), the static electricity of the entire static electricity generating portion can be reduced at once to the ground (typically, a game machine installation area (typically a game machine installation area in a game hall) Island), the same applies hereinafter)) (FIG. 9A). Alternatively, a plurality of static electricity generating portions of the pachinko machine are electrically connected to each other with a conductive sheet 41, and the conductive sheet 41 is connected to one portion of a conductor portion (metal portion) of the pachinko machine by a lead wire 37 or the like. It may be electrically connected. In this case, by providing the grounding line 36 on the conductor portion, the static electricity of the entire static electricity generating portion can be flushed to the ground at once (FIG. 9B). Alternatively, a plurality of static electricity generating portions and a plurality of conductor portions (metal portions) of the pachinko machine are electrically connected to each other by a conductive sheet 42, and the conductor portions are electrically connected to each other by a conductive sheet 40. May be connected. In this case, the conductive sheet 3
