Description

  The present invention relates to a gaming machine, and more particularly, to a corner chamfering (chamfering) structure of a corner decoration of a game board.

  A gaming machine such as a pachinko machine can be attached to the base frame or removed from the base frame when replacing the game board or repairing various devices. In recent years, symbol display devices and the like have become larger, and the load on the game board tends to increase accordingly.

  Conventionally, in order to firmly fix such a game board to a base frame, a movable locking device (for example, a rotation) that stops the base frame and the game board on a corner decoration that partitions the game area near the four corners of the game board. A gaming machine provided with a formula or a bucks type is known. In this type of gaming machine, for example, as shown in Patent Document 1, two locking devices are attached to the side edges of the four corners of the game board, and a total of four fasteners are attached to the base frame. stop. When the game board is fitted into the base frame, the game board is pushed horizontally from the front of the base frame, and the above-mentioned four locking devices are locked while maintaining the mounted state.

  However, in such a gaming machine, it is necessary to perform the above-described mounting operation with the glass frame opened, so that the gaming board is fitted in a narrow space on the hinge side of the base frame, and the upper and lower locking tools are attached. Each locking operation is extremely troublesome and troublesome.

  On the other hand, among the four locking devices of the game board, the locking device on the hinge side is replaced with the locking structure of the locking claw of the base frame and the locking groove of the corner decoration. There is a gaming machine that stops the game board (Patent Document 2 etc.).

  According to such a gaming machine, first, the game board is obliquely inserted from the front of the base frame to the hinge side, and the engaging groove of the corner decoration is fitted into the engaging claw of the base frame. Next, with the side end (fixed end) on the hinge side of the game board as an axis, the other side end (free end) is rotated to fit the game board into the base frame. In this state, if the two locking devices on the free end side of the game board are locked, the game board can be fixed to the base frame more easily than a gaming machine having four locking devices in the upper, lower, left and right directions. .

Japanese Patent Application Laid-Open No. 2003-144639 JP-A-11-169519

However, the configuration of the conventional gaming machine as described above has the following problems.
(1) Since the corner decoration side edge protruding portion is hooked on the locking claw of the base frame and used as the pivot shaft of the fixed end of the game board, there is a possibility that such a hooked portion may be damaged or deformed. .
(2) When the game board is inserted on the hinge side of the base frame, the side edge protruding portion of the corner decoration gets in the way.
(3) Since the corner end side protruding portion is hooked on the toe of the locking claw, a gap about the length of the locking claw is likely to occur between the base frame and the game board.

  The present invention has been made in view of such a current situation, and provides a gaming machine capable of smoothly and accurately mounting a game board on a base frame while ensuring a high structural strength of a corner decoration. The purpose is that.

[First invention]
The gaming machine of the present invention (first invention) is a gaming machine in which a gaming board is inserted obliquely forward from the hinge side of the base frame, and the gaming board is mounted on the base frame while rotating.
A locking claw provided on the hinge-side frame surface of the base frame;
Provided at a side end portion of the corner decoration of the game board, and a locking groove that fits into the locking claw and stops the game board to the base frame,
The side end portion of the corner decoration is a chamfered surface that is inclined toward the center of the board surface from the rear to the front of the game board.

In the configuration of the present invention (first invention), when a game board is mounted on the base frame, the game board is inserted obliquely from the front side on the hinge side of the base frame, and a corner decoration locking groove is formed on the base frame locking claw. At the same time, the corner face of the corner decoration faces the frame of the base frame.
Next, one side end (fixed end) of the game board, that is, the side end on the hinge side is used as an axis, and the other side end (free end) is rotated to fit the game board into the base frame.

  As described above, the conventional corner decoration structure has a structure in which the corner decoration side end protrusions are hooked on the locking claws of the base frame and used as a rotation shaft in order to improve the operability when the game board is rotated. Met. The present invention is a modification of such a conventional idea, in which a corner portion is not provided with a protruding portion as a starting point of rotation, and a corner surface is formed on the side end portion of the corner ornament, thereby The side edge portion of the corner decoration is prevented from interfering with the frame surface of the base frame during insertion and rotation.

  As a result, according to the configuration of the present invention, the structural strength of the side edge portion of the corner decoration can be kept high, and the operability at the time of insertion and rotation of the game board into the base frame is improved. . Further, the corner decoration of the corner frame can be brought close to the frame surface of the base frame so that the gap between the base frame and the game board can be closed and these can be mounted.

[Second invention]
When fitting the corner ornamental locking groove into the locking claw of the base frame, depending on the angle of rise of the groove wall surface of the locking groove, the tip of the locking claw may be locked when the game board is inserted or rotated. It may get in the way when hitting the groove wall of the groove.

A gaming machine of the present invention (second invention) is a gaming machine having the configuration of the first invention,
The corner decoration locking groove is provided with a flank that slopes away from the front end of the locking claw from the rear to the front of the game board.

  According to such a configuration, a sufficient distance can be maintained between the flank and the tip of the locking claw in the locking groove of the base corner decoration, and contact between both can be avoided. This makes it possible to perform the work of mounting the game board on the base frame more comfortably.

[Third invention]
In general, a corner decoration of a game board is fixed to a front surface of a base plate made of a plywood board or the like with screws or the like. As described above, when the locking groove is provided at the side edge of the corner decoration, the plate surface of the base plate is exposed in the locking groove, and the locking claw of the base frame passes through the locking groove to cover the surface of the base plate. There is a risk of scuffing. Usually, the base plate has a softer surface than a synthetic resin corner decoration and is likely to have dents and wrinkles. Therefore, it is desirable to prevent the above-described problems in advance.

A gaming machine of the present invention (third invention) is a gaming machine having the configuration of the first invention,
It is equipped with a game board in which a corner decoration made of synthetic resin is attached to a base board made of plywood,
The corner decoration locking groove is provided with a partition plate that is in close contact with the plate surface of the base plate and partitions the plate surface of the base plate and the groove space of the locking groove.

  According to such a configuration, the locking groove of the corner decoration is partitioned from the plate surface of the base plate by the partition plate, so that when the locking claw is fitted into the locking groove, the tip of the locking claw is There is no direct contact with the board. Thereby, it can prevent that a dent and a wrinkle adhere to the board surface of a base board.

  According to the third aspect of the invention, since the partition plate is provided in close contact with the surface of the base plate, the gap between the game board and the locking claw is adjusted by the thickness of the partition plate, and the hinge of the base frame The incidental effect that the fixed state of the game board on the side can be stabilized can also be obtained.

[Inventions 1-3]
The present invention (first to third inventions) can be applied to various gaming machines having a corner decoration at the side end of the game board. For example, it is effective when applied to a gaming machine such as a pachinko machine, an arrangement ball machine, or a sparrow ball game machine.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, the present invention is applied to a pachinko machine.
As shown in FIG. 1, in the gaming machine 10, a main body frame (base frame) 13 and a glass frame 14 are attached to an outer frame 12. A game board mounting frame portion 93 (see FIG. 11) is provided at the front portion of the opening formed in the main body frame 13, and the game board 15 is detachably attached to the game board mounting frame portion 93. The main body frame 13 and the glass frame 14 are opened and closed to the front side of the gaming machine 10 by a hinge 16.

  Below the game board 15, a handle 17 for launching a game ball is provided. When the handle 17 is operated, a game ball is launched on the launch rail 18 and is discharged to the game area P of the game board 15 through a guide passage between the outer rail 15a and the inner rail 15b.

  As shown in FIG. 2, the game area P is provided with guide nails (not shown) for restricting the falling direction of the game ball, and a symbol display device 30 for displaying a lottery symbol between these guide nails, a lottery symbol A starting port 27 for starting display, a general winning port 28, an attacker device 29 for opening and closing at the time of a big hit and encouraging a winning game ball are arranged (see FIG. 2).

  The game board 15 includes a base plate 21 made of a plate material such as veneer and a rail unit 22 made of a plastic molding material (synthetic resin). A game area P is partitioned into a portion of the board surface of the game board 15 surrounded by the rail unit 22. A cell image sheet is affixed to the board surface of the game area P, and decorative printing for exciting games such as symbols, characters, characters, and backgrounds is applied to the sheet surface. The player views the printed surface through the glass frame 14 (see FIG. 1).

  The rail unit 22 includes an outer rail unit 22A, an intermediate rail unit 22B, and an inner rail unit 22C. Corner decorations 91 a to 91 d (see FIG. 2) that cover the four corners of the base plate 12 are integrally formed outside the game area P of each rail unit 22 </ b> A to 22 </ b> C. The corner decorations 91a to 91d are connected to each other vertically and horizontally and cover almost the entire board surface outside the game area P.

The outer rail unit 22A passes from the vicinity of the outer rail start end to the upper end of the game board 15 through the left end of the game board 15, and extends to the vicinity of the outer rail end. The intermediate rail unit 22 </ b> B extends downward from near the end of the outer rail through the right end of the game board 15 and extends to the vicinity of the lower center of the game board 15. The inner rail unit 22C extends upward from the vicinity of the lower center of the game board 15 along the inner side surface of the outer rail unit 22A.
As shown in FIG. 3, the outer rail unit 22 </ b> A and the intermediate rail unit 22 </ b> B are connected by a connecting pin 25, while the intermediate rail unit 22 </ b> B and the inner rail unit 22 </ b> C are connected by a connecting screw 26. .

As shown in FIGS. 5 and 6, bosses 31a to 31f through which fixing screws are passed and press-fit pins 32a to 32d are formed on the back surface of the outer rail unit 22A at a predetermined interval.
As shown in FIGS. 8 to 10, bosses 31g to 31i through which fixing screws are passed and press-fit pins 32e to 32h are formed on the back surfaces of the intermediate rail unit 22B and the inner rail unit 22C at a predetermined interval. Yes.
The rail units 22A to 22C and the base plate 21 are attached by aligning the bosses 31a to 31i and the press-fit pins 32a to 32h with the fixing holes formed in the base plate 21 in advance, and fixing screws and press-fit pins 32a. This is done by stopping at ~ 32h.

As shown in FIG. 5, a metal guide rail R is attached along the inner peripheral surface of the outer rail unit 22A in the rail length direction. The game ball rolls on the rail surface of the guide rail R, and the inner peripheral surface of the outer rail unit 22A does not touch the game ball directly.
Note that such a metal guide rail R is employed only for the outer rail unit 22A, and is not employed for the intermediate rail unit 22B and the inner rail unit 22C. That is, in the normal gaming state, the frequency of the game balls coming into contact with the rail surfaces of the intermediate rail unit 22B and the inner rail unit 22C is low. Therefore, in these units 22B and 22C, the resin molding surface (inner The peripheral surface) is used as it is as the rail surface of the game ball.

  The corner decorations 91a and 91b on the hinge side of the game board 15 are formed with locking grooves 92 and 92 at two locations on the upper and lower sides (see FIG. 2). These locking grooves 92 and 92 have a groove width and a groove length that fit into locking claws 94 and 94 of the main body frame 13 described later.

  Locking claws 94 are formed on the frame surface on the hinge side of the rectangular game board mounting frame portion 93 of the main body frame 13 (see FIG. 11). The locking claws 94 and 94 are disposed at two positions on the upper and lower sides of the frame surface at the same interval and height as the locking grooves 92 and 92. A back plate portion 94a (see FIG. 12) extends in the vertical direction of the locking claws 94, 94, and the side edge of the game board 15 is between the back plate surface of the back plate portion 94a and the game board mounting surface 93a. Stop so as to sandwich the part.

Next, the configuration of the side end portions of the corner decorations 91a and 91b will be described.
FIG. 13 is a plan view of the gaming machine 10 as viewed from above. The corner decorations 91a and 91b of the game board 15 have a chamfered surface 95 at their side ends (see FIG. 14). The chamfered surface 95 is an inclined surface that inclines toward the center of the game board 15 from the rear to the front of the game board 15, and extends with a uniform inclination in the height direction of the corner decorations 91a and 91b (FIG. 3). reference).

  As shown in FIG. 15, the locking groove 92 is formed by cutting out the chamfered surface 95 of the corner decoration 95a. The groove wall surfaces 92a, 92a and the groove wall surface 92b of the locking groove 92 are connected in a U-shape, and a groove space for fitting the locking claw 94 is formed.

The groove wall surfaces 92a and 92a rise substantially perpendicular to the surface of the base plate 21 and face each other.
The groove wall surface 92b is a flank surface that is inclined in the direction away from the center of the board surface, that is, away from the locking claw 94, from the rear to the front of the board surface (see FIG. 16).

  A partition plate 16 is provided at the bottom of the locking groove 92. The partition plate 96 is integrally formed with the corner decorations 91 a and 91 b and partitions the groove space of the locking groove 92 and the plate surface of the base plate 21. The back surface of the partition plate 96 coincides with the back surfaces of the corner decorations 91 a and 91 b and is in close contact with the base plate 21.

  Thus, by forming the partition plate 16 in the groove space of the locking groove 92, the locking claw 94 does not directly contact the plate surface of the base plate 21. Accordingly, when the game board 15 is fitted into the main body frame 13, the surface of the base plate 21 is prevented from being dented or scratched at the tip of the locking claw 94.

  Further, by adjusting the thickness D (see FIG. 16) of the partition plate 15 when the corner decorations 91a and 91b are formed, the gap between the game board 15 and the locking claws 95 can be easily filled. It becomes possible to keep the side end portion in a stable mounting state without rattling.

  When the game board 15 is mounted on the main body frame 13, as shown in FIG. 17, the game board 15 is inserted into the main body frame 13 from obliquely forward, and the locking groove 92 of the game board 15 is fitted into the locking claw 94. At this time, the cornering surfaces 95 of the corner decorations 91a and 91b face the frame surface of the game board mounting frame portion 93 so that the side edges of the game board 15 abut against the frame surface.

Next, the other side end (free end) of the game board 15 is rotated around the side end (fixed end) of the game board 15 that has come into contact with the frame surface, and at the same time, the side end (fixed end) of the game board 15 is rotated. Is pushed toward the frame surface (see FIG. 18). As a result, the game board 15 is completely fitted into the main body frame 13.
In this state, the locking devices 90 and 90 (see FIGS. 2 and 3) on the free end side of the game board 15 are locked, and the game board 15 is fixed to the main body frame 13.

  According to the configuration of the present embodiment, the side ends of the corner decorations 91 a and 91 b are the chamfered surfaces 95, so that the side end (fixed end) of the game board 15 is attached to the frame surface of the game board mounting frame section 93. The operation of insertion and rotation can be performed while abutting. That is, even if the side end (fixed end) of the game board 15 does not have a portion such as a protruding portion as a starting point of rotation, the game board 15 can be smoothly attached to the main body frame 13.

Further, since the side end portions of the corner decorations 91a and 91b are the chamfered surfaces 95, the structural strength can be kept high, and damage and deformation are unlikely to occur.
Further, when the game board 15 is mounted on the main body frame 13, the cornering surfaces 95 of the corner decorations 91a and 91b do not interfere with the work.
Further, since the side edge of the game board 15 can be pushed toward the frame surface of the game board mounting frame portion 93, the game board 15 can be accommodated in the frame of the main body frame 13 without any gap.

  Furthermore, in the present embodiment, the groove wall surface (flank) 92b of the locking groove 92 is inclined in a direction away from the toe of the locking claw 94, so that the toe of the locking board 92 is moved to the groove wall surface (relief) when the game board 15 is mounted. Surface) 92b. For this reason, the operation of inserting and rotating the game board 15 can be comfortably performed without being obstructed by the locking claw 94.

The configuration of the gaming machine 10 according to the present embodiment has been described above, but the embodiment of the present invention is not limited to this, and the configuration may be changed as necessary.
For example, in the above-described embodiment, the locking claws 94 and 94 and the locking grooves 92 and 92 are provided in two places in the height direction of the game board 15, but these numbers may be only one place. Three or more locations may be used.
The lengths and widths of the locking claws 94 and the locking grooves 92 are not limited to the above embodiment.

[Other inventions]
Next, another invention adopted in the gaming machine 10 will be described. In addition to the invention related to the corner ornament locking structure described above, a plurality of inventions are applied to the gaming machine 10 in various places.

[Other invention 1: Static elimination structure of cell image sheet]
In general, a game board such as a pachinko machine has a cell image sheet pasted on a board surface made of a plywood board or the like. The cell image sheet decorates the game board surface with an image printed on a transparent film, and among them, there is a cell image sheet having a metallic luster. Such a cell image sheet is printed with a decorative pattern on a transparent film such as PET (polyethylene terephthalate) or cabloid, and an aluminum foil (metal layer) is pasted thereon, and further adhered to the metal layer. It is formed by pasting backing paper with an agent. The reflection of light by such a metal layer adds a metallic texture to the printed design and background, creating a unique atmosphere in the game area.

  However, such cell picture sheets are easily charged with static electricity on the metal layer during gaming, and as a result, the game ball sparks when it comes into contact with an accessory or a nail or the like, and electromagnetic noise that causes malfunction of various control devices is generated. Easy to cause.

Therefore, the gaming machine of the present invention is a gaming machine in which a cell image sheet having a metal layer is attached to the surface of a gaming board,
A static elimination fitting that is driven through the cell picture sheet into the surface of the game board,
This static eliminator is
An intrusion portion that is driven into the cell image sheet and contacts the metal layer;
A relay portion that is connected to the penetration portion, is exposed on the surface of the game board, and contacts a predetermined ground terminal around the game board.

  According to the gaming machine of the present invention, when the static elimination fitting is driven into the surface of the game board, the penetration portion penetrates the cell drawing sheet and comes into contact with the metal layer inside the sheet. On the other hand, the relay part of the static elimination fitting contacts an existing ground terminal (for example, a skeleton iron plate of a glass frame) installed in the gaming machine. As a result, the metal layer of the cell drawing sheet is grounded via the static elimination fitting, and even if static electricity is generated in the metal layer, the charge can be immediately released to the outside.

The gaming machine of the present invention is a gaming machine in which a cell picture sheet having a metal layer is attached to the surface of a gaming board,
A static elimination fitting that is driven through the cell picture sheet into the surface of the game board,
This static elimination metal fitting has a penetration part which is driven into the cell picture sheet and comes into contact with the metal layer, and the penetration part is preferably a plate blade.

  According to such a configuration, since the plate blade-shaped static elimination fitting is driven into the cell image sheet, the cell image sheet is divided by the blade edge, and the transparent film layer pushed downward covers the peripheral surface, and shavings are not generated. It does not occur, and the side surface of the plate blade easily comes into contact with the metal layer. Further, since the contact area between the plate blade and the metal layer is increased, a wide conductive path can be secured. The plate blade includes not only a saw blade and a knife blade but also an arc-shaped or cylindrical blade.

Hereinafter, specific examples of the present invention will be described based on the configuration of the gaming machine 10.
FIGS. 19A and 19B are enlarged views of the outer rail end portion on the back surface side of the outer rail unit 22A and shown in FIG. 5 and FIG. 6 [Z].
As shown in FIG. 19A, the back surface near the end of the outer rail is a pedestal 40 for attaching the static elimination fitting 50, and the static elimination fitting 50 is set on the pedestal 40 in a predetermined direction. The static elimination fitting 50 is sandwiched between the base 40 and the base plate 21 in contact with the cell image sheet.

As shown in FIG. 20, the pedestal 40 includes a boss 31a raised on the unit front panel 41, partition walls 44, 45, 46, and the like. The boss 31a is a boss for screwing the outer rail unit 21A to the base plate 21 near the start end of the outer rail.
The boss 31a and the partition walls 44, 45, 46 have a uniform upper end surface in FIG. 20, and support the static elimination fitting 50 at these end surfaces.

  A pair of support pins 48 are formed on both sides of the boss 31a of the base 40 (see FIG. 19). The tips of these support pins 48 protrude to a position higher than the upper end surface of the boss 31a (support surface of the static elimination fitting 50), and the static elimination fitting 50 is sandwiched between the support pins 48.

  Between the unit side panel 42 and the partition wall 44, a storage space for a convex fold (bent surface) of the static elimination fitting 50 described later is provided. This storage space is opened to the front side of the game board 15 by a small window W (see FIG. 20) that opens in the unit front panel 41.

  As shown in FIGS. 21 and 22, the static elimination fitting 50 is formed by bending a metal strip, and has a flat folded portion 52 at one end of the flat plate portion 51 and a vertical folded portion at the other end. 53 and the horizontal folding part 54 are continued. A convex fold portion 55 having a U-shaped cross section is provided at a substantially intermediate position of the horizontal fold portion 54.

  A screw hole H <b> 1 is formed in the flat plate portion 51. The screw hole H1 is positioned so as to overlap with the screw hole H2 of the boss 31a when the static elimination fitting 50 is set on the base 40 (see FIG. 20). That is, the fixing screws can be simultaneously passed through these screw holes H1 and H2.

  In the circumferential direction of the screw hole H1, serrated plate blades 58 are continued along the hole surface. As shown in FIG. 23, the plate surface of the plate blade 58 is shaped like a scoop and faces the outside of the screw hole H1 (in the axial direction of the screw hole). Lined up. Such a bevel-shaped plate blade 31a can be formed, for example, by piercing a plate surface of the flat plate portion 51 with a tip cross-shaped drilling tool or the like.

  Arc grooves K1 and K2 are formed on both side ends of the flat plate portion 51 across the screw hole H1. As shown in FIG. 24, the distance between the arc grooves K1 and K2 is substantially equal to the distance between the support pins 48 and 48 described above. As a result, by removing the arc grooves K1 and K2 between the support pins 48, 48, the static elimination fitting 50 can be temporarily fixed to the base 40. Further, the screw hole H2 of the boss 31a and the screw hole H1 of the flat plate portion 51 can be easily aligned by temporary fixing.

  As shown in FIG. 25, the diagonally folded portion 52 is bent at an angle of approximately 45 ° with respect to the length direction of the static elimination fitting 50. A dome-shaped convex portion 52 a is formed on the outer surface of the diagonally folded portion 52. When the static eliminator 50 is set on the pedestal 40, the diagonally folded portion 52 is accommodated in the gap between the partition wall 46 and the guide rail R, and the convex portion 52a contacts the guide rail R. That is, a conductive path between the guide rail R and the static elimination fitting 50 is secured by the contact between the convex portion 52a and the guide rail R.

  The vertical folding portion 53 and the horizontal folding portion 54 form bending angles that are substantially perpendicular and parallel to the flat plate portion 51, respectively. The length of the vertically folded portion 53 substantially matches the depth of the storage space between the unit side panel 42 and the partition wall 44. As a result, as shown in FIG. 20, the vertical folding portion 53 can be inserted to the bottom position of the storage space, and at this time, the plate surface of the horizontal folding portion 54 is the bottom surface of the storage space (the back surface of the unit front panel 41). Overlapping.

Rectangular through holes S1 and S2 are formed in the vicinity of the folding lines of the vertical folding portion 53 and the horizontal folding portion 54 (see FIG. 21). These through holes S <b> 1 and S <b> 2 serve to absorb the distortion of the plate surface of the static elimination fitting 50.
Further, as shown in FIG. 20, the through hole S <b> 1 fits into the protrusion 44 a of the partition wall 44, and stabilizes the mounting state of the static elimination fitting 50 to the base 40.

  The convex fold 55 is raised substantially perpendicular to the plate surface of the lateral fold 54, and when the static elimination fitting 50 is set on the base 40, the convex fold 55 fits into the small window W of the unit front panel 41. (See FIG. 20). When the vicinity of the rail end of the rail unit 22 is viewed from the front of the game board 15, the projecting folds 55 protrude from the front of the unit (see FIGS. 1 and 2).

  As shown in FIG. 1, an iron plate serving as a frame skeleton is exposed on the back side of the glass frame 14, and a part of the iron plate is bent to form a tongue-shaped ground terminal 59. The ground terminal 59 is grounded by the existing ground wiring of the gaming machine 10 including the frame skeleton (metal part) of the glass frame 14. When the glass frame 14 is closed to the main body frame 13 side from the opened state of the gaming machine 10 shown in FIG. 1, the ground terminal 59 comes into contact with the convex folded portion 55 of the static elimination fitting 50, and the static elimination fitting 50 is connected to the ground wiring. .

  The contact between the static elimination fitting 50 and the ground terminal 59 is performed by the convex folding portion 55 being pushed and bent by the ground terminal 59 when the glass frame is closed. For this reason, the bent surface of the convex folded portion 55 is elastically deformed and brought into close contact with the metal surface of the ground terminal 59, and the contact state is kept good.

Next, static electricity neutralizing action by the gaming machine 10 will be described.
When the rail unit 22 is fixed to the base plate 21, the static elimination fitting 50 is set on the pedestal portion 40, and when the boss 31 a is screwed through the base plate 21, the entire rail unit 22 is screwed by the screw N as shown in FIG. Is pressed against the base plate 21, and at the same time, the plate blade 58 of the static elimination fitting 50 sandwiched between the boss 31 a and the base plate 21 penetrates the cell image sheet L and pierces the base plate 21. Then, the side surface of the plate blade 58 comes into contact with the metal layer L3 of the cell image sheet L, and the metal layer L3 is grounded. In the cell image sheet L shown in FIG. 26, the lowermost layer L1 is a backing paper layer, the second layer L2 is an adhesive layer, the third layer L3 is a metal layer such as aluminum foil, the fourth layer L4 is an ink layer, the uppermost layer. The upper layer L5 (surface layer) indicates a transparent film layer.

  In this way, according to the gaming machine 10, since the metal layer L3 of the cell drawing sheet L contacts the static eliminator 50 via the plate blade 58 and forms a path to be grounded, the metal layer L3 is charged with static electricity. Even then, static electricity is immediately discharged to the outside from the static elimination metal fitting 50 through the ground terminal. As a result, electromagnetic wave noise due to static electricity is unlikely to occur in the gaming machine 10, and malfunction of the control device or the like can be prevented in advance.

  In addition, since the gaming machine 10 has a configuration in which the blade edge of the plate blade 58 is inserted into the cell drawing sheet L and comes into contact with the metal layer L3, each layer of the cell drawing sheet L is placed below the base plate 21 together with the plate blade 58. Hard to be pushed in. Thereby, the static elimination metal fitting 50 and the metal layer L3 contact reliably without being interrupted by other layers, and the reliability of the conductive path is increased.

  Further, since the plate blade 58 is raised along the hole surface of the screw hole H of the static elimination metal fitting 50, the plate blade 58 can be simultaneously inserted into the cell image sheet L when the static elimination metal fitting 50 is fixed with the screw N. In addition, it is possible to reduce the trouble of mounting the static elimination fitting 50.

Further, as described above, since the static elimination fitting 50 is also in contact with the metal guide rail R at the diagonally folded portion 52, the guide rail R is charged with static electricity, for example, when the launch ball is charged. However, such static electricity can be removed at the same time.
Further, since the static elimination fitting 50 has a simple configuration in which a band plate material is formed by bending, the manufacturing cost can be relatively low.

  In addition, this embodiment may be accompanied by the change of the component part as needed. For example, in the above-described embodiment, the static elimination fitting 50 is attached to the outer rail unit 22A, but instead, it may be attached to the intermediate rail unit 22B or the inner rail unit 22C. Further, the plurality of plate blades 58 of the static elimination fitting 50 are arranged in a ring shape along the hole surface of the screw hole H1, but it is not always necessary to provide all of them. You may make it the structure of a plate-shaped blade. Moreover, the plate blade of the static elimination metal fitting 50 is not limited to a cylindrical shape, and may be a flat plate shape.

In the vicinity of the side end, two bosses B1 are formed in the vertical direction (see FIGS. 9 and 10).

  As shown in FIGS. 27 and 28, a collecting rod 61 and a substrate box 62 are fixed to the lower back of the base plate 21, and among these, four corners of the collecting rod 61 are kept at the same interval as the boss B1. Two bosses B2 are formed.

As shown in FIG. 29, a through hole T is formed in a lower portion of the base plate 21 at a position corresponding to the bosses B and B2.
When the rail unit 22 and the collecting rod 61 are fixed to the base plate 21, both the bosses B and B <b> 2 are aligned with the through hole T with the base plate 21 interposed therebetween, and are fastened together with screws 63.

  In this way, by fastening the rail unit 22 and the collecting rod 61 together with the base plate 21, these fixing operations are simplified. Further, the number of press-fit pins 32a to 32h (see FIGS. 6 and 10) of the rail unit 22 is relatively small, and the fixing device for press-fitting the rail unit 22 into the base plate 21 can be easily downsized. Work such as positioning to the is easy.
