Description

  The present invention relates to a gaming machine, and more particularly, to a charge removal structure for a decorative sheet (cell image sheet) of a game board.

In general, a game board such as a pachinko machine has a cell picture sheet attached to a board made of a veneer 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.
As related prior art, the following Patent Documents 1 and 2 are disclosed.

Japanese Patent Laid-Open No. 10-99491 JP 2002-191773 A

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.
The present invention has been made in view of such a current situation, and an object of the present invention is to provide a gaming machine capable of quickly and reliably removing static electricity charged in a metal layer of a cell drawing sheet.

This onset Ming gaming machine, as described in claim 1,
A game board in which a cell image sheet having a conductive metal layer is provided on the surface of the base plate and the surface of the cell image sheet is surrounded by an outer rail and an inner rail to form a game area;
A plastic molded product that is integrally provided with a boss through which a metal fixing screw is inserted, and that is fixed to a corner of the game board with the fixing screw passed through the boss;
A conductive static elimination fitting disposed between the boss and the game board and having a screw hole through which the fixing screw can be inserted, and further electrically connected to a separately formed ground wiring;
The tongue hole of the static elimination fitting has a screw hole diameter larger than the screw thread diameter of the fixing screw and contacts the screw groove surface of the fixing screw while elastically deforming from the hole edge toward the diameter direction. Are projected at equal intervals,
By fixing the fixing screw to the game board, the plastic molded product is fixed to the game board via the boss, and the tongue plate is brought into contact with the thread groove surface of the fixing screw to thereby form the metal layer of the cell drawing sheet. There is provided a gaming machine in which the static elimination fitting is electrically conducted through the fixing screw.

According to such a configuration, when the fixing screw is screwed into the screw hole, the tongue plate contacts the screw groove surface (spiral inclined surface) while being elastically deformed so as to be hard to be inserted into the screw groove. That is, the fixing screw is screwed into the screw hole so as to be guided by the tongue plate. As a result, the thread of the fixing screw is not cut off at the hole edge of the screw hole.
Further, since the tongue plate contacts the thread groove surface while being elastically deformed, electrical contact between the fixing screw (penetrating portion) and the static elimination fitting (relay portion) can be reliably ensured.

The present onset Ming gaming machine, before Symbol tongue plate is characterized in that it is provided two or more in the inner circumferential direction of the equally spaced positions of the screw holes.

According to such a configuration, the fixing screw can be supported in the vicinity of the center of the screw hole so as to be surrounded by the tongue plate, so that the axis of the fixing screw can be easily kept straight with respect to the sheet metal. As a result, the fixing screw can be easily tightened.
The specific arrangement of the tongue plate is, for example, two at 180 ° intervals along the inner periphery of the screw hole, three at 120 ° intervals, four at 90 ° intervals, six at 60 ° intervals, and 45 ° intervals. 8 etc. can be adopted.

The tongue plate is preferably formed so as to form a curved outline from the vicinity of the rising edge of the hole to the tip of the tongue plate .

  According to such a configuration, since there are no corners in the screw hole shape including the tongue plate, the screw hole can be easily punched into the sheet metal. Further, when the tongue plate is elastically deformed, the stress is less likely to concentrate at a specific location, and the bending strength of the tongue plate can be easily increased.

In addition, it is preferable that the static elimination fitting is in contact with a metal rail of the game board .

  According to such a configuration, a conductive path is formed between the metal layer of the cell drawing sheet and the metal rail of the game board via the static elimination fitting. Thereby, the static electricity accumulated in the metal layer of the cell drawing sheet can be efficiently eliminated.

Also, preferably, may be so as to contact the front Symbol neutralization bracket to the ground terminal of the by elastic deformation glass frame for opening and closing the bent surface on the front side of the gaming machine.

  According to such a structure, a favorable contact state can be maintained between the static elimination fitting and the ground terminal of the glass frame when the glass frame is closed. That is, when the glass frame is opened, the ground terminal is separated from the game board, and the static elimination fitting and the ground terminal are blocked. On the other hand, when the glass frame is closed, the ground terminal pressurizes the static elimination fitting and elastically deforms its bent surface. Thereby, a bent surface closely_contact | adheres to a ground terminal, and a contact state can be stabilized.

Preferably, the static elimination fitting is formed by bending a metal strip .

  According to such a configuration, the static elimination fitting can be manufactured by simple processing of a metal strip material, and the manufacturing cost of the gaming machine can be suppressed. In addition, it is easy to attach a static elimination fitting even in a narrow space, and the static elimination fitting is unlikely to interfere with other components on the game board.

The present invention can be applied to various gaming machines having a configuration in which a cell image sheet having a metal layer is pasted on a game board surface. 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 .

[First Embodiment]
As shown in FIG. 1, in the gaming machine 10, a main body frame 13 and a glass frame 14 are attached to an outer frame 12. A game board mounting frame portion 93 (see FIG. 40) is provided at the front 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. 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. Of these, corner decorations that cover the four corners of the base plate 12 are integrally formed outside the game area P of the rail units 22A and 22B.

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.
On the other hand, 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 predetermined intervals. Has been.
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 rail surfaces of the intermediate rail unit 22B and the inner rail unit 22C are less frequently contacted by the game balls. Therefore, in these units 22B and 22C, the resin molding surface (inner circumference) that partitions the game area P is used. Surface) is used as a rail surface of the game ball as it is.

FIGS. 11A and 11B are enlarged views of the outer rail terminal 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. 11A, 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. 12, 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 2 2 A to the base plate 21 near the end of the outer rail.
In FIG. 12, the boss 31a and the partition walls 44, 45, and 46 have a uniform upper end surface, and the end fitting 50 is supported by these end surfaces.

  In the base 40, a pair of support pins 48 are formed on both sides of the boss 31a (see FIG. 11). 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 and 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. 12) opened in the unit front panel 41.

  As shown in FIGS. 13 and 14, the static elimination fitting 50 is a sheet metal formed by bending a metal strip, and has a flat folding portion 52 at one end of the flat plate portion 51 and a vertical folding 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. 12). That is, the fixing screws can be simultaneously passed through these screw holes H1 and H2.

  A serrated plate blade 58 is connected to the hole edge of the screw hole H1 in the circumferential direction along the hole surface. As shown in FIG. 15, the plate surface of the plate blade 58 is shaped like a scoop and faces the outside of the screw hole H <b> 1 (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. 16, 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. 17, 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. 12, 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. 13). 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. 12, 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 pedestal 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. 12). 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, the static elimination effect of static electricity by the static elimination fitting 50 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 into 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. 18, 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 divides the cell image sheet L with the blade edge of the plate blade 58 and brings it into contact with the static elimination fitting 50 and the metal layer L3, each layer of the cell image sheet L is attached to the base plate 21 together with the plate blade 58. Hard to be pushed down. 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.

  As mentioned above, although embodiment which employ | adopts a plate blade type static elimination metal fitting was described, embodiment of this invention may be accompanied by the change of the structure as needed, without being limited to this. 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.

[Second Embodiment]
Next, an embodiment of a gaming machine that employs a blade-type static elimination fitting will be described.
This type of gaming machine uses a static elimination fitting 120 shown in FIGS. 19 and 20 in place of the aforementioned static elimination fitting 50. A ground path of the cell image sheet is secured through a metal fixing screw (screw screw) through the central screw hole H1 of the static elimination fitting 120.

  Since the basic configuration of the gaming machine is substantially the same as the configuration of the first embodiment described above (see FIGS. 1 to 10), the description of each component such as the rail unit is the same as the description of the first embodiment. Follow.

In the second embodiment, FIGS. 21A and 21B are enlarged views of the outer rail terminal portion shown on the back side of the outer rail unit 22A and shown in FIG. 5 and FIG. 6 [Z].
As shown in FIGS. 21A and 21B, the back surface near the end of the outer rail is a pedestal 40 for attaching the static eliminator 120, and the static eliminator 120 is set in a predetermined direction on the pedestal 40. The The static elimination fitting 120 is sandwiched between the pedestal 40 and the base plate 21 in contact with the cell image sheet.

As shown in FIG. 22, 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 2 2 A to the base plate 21 near the end of the outer rail.
The boss 31a and the partition walls 44, 45, and 46 have a uniform upper end surface in FIG. 22, and support the static elimination fitting 120 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. 23). The tips of the support pins 48 protrude to a position higher than the upper end surface of the boss 31a (the support surface of the static elimination fitting 120), and the static elimination fitting 120 is sandwiched between the support pins 48.

  Between the unit side panel 42 and the partition wall 44, a storage space for a convex folded portion (bent surface) of the static elimination fitting 120 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. 22) opening in the unit front panel 41.

  As shown in FIG. 19 and FIG. 20, the static elimination fitting 120 is a sheet metal formed by bending a metal band plate, and has a flat folding portion 122 at one end of the flat plate portion 121 and a vertical folding portion at the other end. 123 and the horizontal folding part 124 are continued. A convex fold 125 having a U-shaped cross section is provided at an approximately middle position of the lateral fold 124.

  A screw hole H <b> 1 is formed in the flat plate portion 121. 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. 22). That is, a fixing screw (screw screw) can be simultaneously passed through these screw holes H1 and H2.

  Tongue plates 128 and 128 protrude from the hole edge of the screw hole H1. The tongue plates 128 are arranged at intervals of 180 ° on the inner periphery of the screw hole H1, and face the diameter direction and extend toward the center of the hole. The plate surfaces of the tongue plates 128, 128 are continuous with the plate surface of the flat plate portion 121, and bend so that the tip thereof swings up and down the screw hole H <b> 1. That is, the plate surfaces of the tongue plates 128, 128 are elastically deformed along the thread groove surface of the fixing screw (screw screw) as will be described later. Such tongue plates 128, 128 can be formed, for example, by punching a sheet metal.

FIG. 25 shows the relationship between the size of the fixing screw (screw screw) N of the static elimination fitting 120 and the screw hole H1. In FIG. 25, the alternate long and short dash line of the fixing screw N indicates the outer shape of the screw head, N1 indicates a screw groove, and N2 indicates a screw thread.
The screw hole diameter D1 of the screw hole H1 is sufficiently larger than the screw thread diameter of the screw thread N1 of the fixing screw N. Thus, when the fixing screw N is screwed into the screw hole H1, the screw thread N2 does not hit the hole edge of the screw hole H1.
On the other hand, the distance D2 between the tips of the tongue plates 128, 128 is smaller than the outer diameter of the screw groove N1 of the fixing screw N. Thus, when the fixing screw N is screwed into the screw hole H1, the tongue plates 128 and 128 are bent and come into contact with the groove surface of the screw groove N1.

As shown in FIG. 25, and only if the tip from rising near the hole edge of the tongue plate 128, 128 is formed so as to form the outline of the curves. Thus, by not providing a corner portion in the hole shape of the screw hole H1, the punching process of the screw hole H1 can be easily performed. Further, even if the tongue plates 128, 128 are bent up and down the screw hole H1, it becomes difficult for stress to concentrate on a specific location, and it becomes easy to keep the plate surface strength high.

  Arc grooves K1 and K2 are formed at both ends of the flat plate portion 121 with the screw hole H1 interposed therebetween. The distance between the arc grooves K1 and K2 is substantially equal to the distance between the support pins 48 and 48 (see FIG. 23). As a result, the antistatic fitting 120 can be temporarily fixed to the pedestal 40 by aligning the arc grooves K1 and K2 between the support pins 48, 48. 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. Such arc grooves K1 and K2 can be omitted if necessary.

  As shown in FIG. 24, the oblique folding portion 122 is bent at an angle of approximately 45 ° with respect to the length direction of the static elimination fitting 120. A warped bent portion 122a is formed at the tip of the diagonally folded portion 122 (see FIGS. 19 and 20). When the static elimination fitting 120 is set on the pedestal 40, the diagonally folded portion 122 fits in the gap between the partition wall 46 and the guide rail R, and the warped bent portion 122 a comes into contact with the guide rail R. That is, the contact between the warped bent portion 122a and the guide rail R secures a conductive path between the guide rail R and the static elimination fitting 120.

  The vertical folding part 123 and the horizontal folding part 124 form bending angles that are substantially perpendicular and parallel to the flat plate part 121, respectively (see FIG. 19). The length of the vertically folded portion 123 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. 22, the vertically folded portion 123 can be inserted to the bottom position of the storage space, and at this time, the plate surface of the lateral folding portion 124 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 part 123 and the horizontal folding part 124 (see FIG. 19). These through holes S <b> 1 and S <b> 2 serve to absorb the distortion of the plate surface of the static elimination fitting 120.
Further, as shown in FIG. 22, 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 120 to the pedestal 40.

  The convex fold 125 is raised substantially perpendicular to the plate surface of the lateral fold 124, and when the static elimination fitting 120 is set on the base 40, the convex fold 125 fits into the small window W of the unit front panel 41. (See FIG. 22). When the vicinity of the rail end of the rail unit 22 is viewed from the front of the game board 15, the protruding fold 125 protrudes 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 125 of the static elimination fitting 120, and the static elimination fitting 120 is connected to the ground wiring. .

  The contact between the static elimination fitting 120 and the ground terminal 59 is performed by the convex folding portion 125 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 125 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, the static elimination effect of static electricity by the static elimination fitting 120 will be described.
When the rail unit 22 is fixed to the base plate 21, as shown in FIG. 26, the static elimination fitting 120 is set on the pedestal portion 40, and the boss 31 a is tightened to the base plate 21 through a metal fixing screw N. Then, the fixing screw N breaks through the cell drawing sheet L and gets into the base plate 21, and comes into contact with the metal layer L3 of the cell drawing sheet L as shown in FIG. At the same time, since the fixing screw N contacts the hole edge of the static elimination fitting 120 (screw hole H1) via the tongue plates 128, 128, the metal layer L3 is grounded through the fixing screw N and the static elimination fitting 120. Become. In the cell image sheet L shown in FIG. 27, 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.

  As described above, according to the gaming machine 10 of the present embodiment, the metal layer L3 of the cell drawing sheet L contacts the static elimination fitting 120 via the fixing screw N and forms a path to be grounded. Even if static electricity is charged, the static electricity is immediately discharged to the outside from the static elimination fitting 120 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.

Further, when the fixing screw N is screwed into the screw hole H1 of the static elimination fitting 120, the tongue plates 128, 128 come into contact with the inclined surface of the screw groove while being elastically deformed, so that the screw of the fixing screw N is formed by the hole edge of the screw hole H1. The mountain is not shaved, and the electrical connection between the static elimination fitting 120 and the fixing screw N can be reliably ensured.
Further, since the fixing screw N is sent downward (tightening direction) in a state where the tongue plates 128 are fitted in the screw grooves, it is difficult to idle.

  Further, since the tongue plates 128, 128 extend facing the diameter direction of the screw hole H1, the fixing screw N can be easily kept near the center of the screw hole H1, and the screwing operation can be easily performed.

Further, as described above, since the static elimination fitting 120 is also in contact with the metal guide rail R at the oblique fold 122, 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.
Furthermore, since the static elimination fitting 120 has a simple configuration in which a band plate material (sheet metal) is formed by bending, the manufacturing cost can be relatively low.

  As mentioned above, although the game machine 10 by the tongue plate type static elimination metal fitting 120 was demonstrated, embodiment of this invention is not limited to this, You may involve the change of the structure as needed. For example, in the embodiment described above, the static elimination fitting 120 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.

  Moreover, in the said embodiment, although the pair of tongue plates 128 and 128 which face the diameter direction of the screw hole H1 were used, the number of tongue plates can also be increased as needed. For example, as shown in FIG. 28, slits may be formed radially at 45 ° intervals in the peripheral portion of the screw hole H1, and a tongue plate 128s may be formed between these slits. Each tongue plate 128s faces each other in the diameter direction of the screw hole H1, and keeps the fixing screw N near the center of the screw hole H1.

Further, as shown in FIG. 29, both the plate blades 128t and 128t and the tongue plates 128u and 128u may be provided at the hole edge of the screw hole H1. The plate blades 128t and 128t face each other in the length direction of the flat plate portion 121, and the tongue plates 128u and 128u are arranged so as to face each other in the width direction of the flat plate portion 121.
According to such a configuration, since the ground path can be formed in both the plate blades 128t and 128t and the tongue plates 128u and 128u, it becomes possible to further improve the reliability of the charge removal of the cell image sheet.

[Other inventions]
Next, another invention adopted in the gaming machine 10 will be described. A plurality of inventions are applied to the gaming machine 10 in addition to the above-described invention relating to the static elimination structure of the cell image sheet.

[Other invention 1: Game board tightening structure]
In a game machine of the type having the rail unit 22 on the game board 15 as in the above embodiment, the number of press-fit pins for fixing the rail unit 22 to the base plate 21 tends to increase. For this reason, the work process at the time of fixing the rail unit 22 to the base board 21 may become complicated, and the problem of causing the enlargement and complexity of a fixing device may arise.

  On the other hand, a collect basket for collecting game balls is usually attached to the back of the game board. The assembly rod is generally fixed to the back surface of the base plate with a screw or the like.

In order to solve the problems as described above, the present invention has focused on the point that the fixing means for the rail unit and the fixing means for the assembly rod are used in common.
That is, the gaming machine of the present invention is a gaming machine comprising a gaming board for fixing the rail unit on the front surface of the base plate and the collective basket on the back surface,
A through hole is formed at a predetermined position of the base plate, and the rail unit and the collecting rod are aligned with the through hole and fastened together with screws.

  According to such a configuration, since the fixing screw of the rail unit and the fixing screw of the assembly rod are made common, the fixing operation of both can be performed at the same time, and the work process is greatly simplified. Further, since the number of dedicated press-fit pins and screws for fixing the rail unit can be reduced, it is difficult to increase the size and complexity of the fixing device.

  When a specific example is shown in the embodiment, the rail unit 22 is a lower part of the outer rail unit 22A, and two bosses B1 (see FIG. 6) vertically in the vicinity of the side end thereof, and a lower part of the intermediate rail unit 22B. In the vicinity of the side end, two bosses B1 are formed in the vertical direction (see FIGS. 9 and 10).

  As shown in FIG. 30 and FIG. 31, 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. 32, a through hole T is formed in a lower portion of the base plate 21 at a position that coincides with 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.

[Other invention 2: Opening and closing mechanism of protective cover]
A protective cover may be provided in the vicinity of the start end of the outer rail of the game board in order to prevent the foul ball (falling ball) and the launch ball from colliding with the front glass. Normally, the protective cover is held almost vertically with respect to the rail surface. On the other hand, when cleaning the rail surface, remove the protective cover or fold the protective cover made of flexible material and look into the rail surface. I am doing so.
However, such a conventional protective cover is troublesome to attach once the protective cover is removed. In addition, when the protective cover is bent, the protective cover tends to be an obstacle during cleaning.

In order to solve the above problems, the gaming machine of the present invention is a gaming machine having a protective cover covering the rail surface in the vicinity of the outer rail starting end of the gaming board.
The protective cover is supported on the front side of the game board by a support shaft so as to be openable and closable, and includes a locking claw that regulates an opening and closing angle of the protective cover in the vicinity of the opening and closing shaft of the protective cover. did.

  According to such a configuration, since the protective cover is supported on the front side of the game board by the support shaft so as to be opened and closed, the opening and closing operation can be easily performed. Moreover, since the opening angle of the protective cover can be kept constant by the locking claw, the protective cover is unlikely to become an obstacle when cleaning the rail surface.

  If a specific example is shown by this embodiment, as shown in FIG. 33, the protective cover 70 will be attached to the vicinity of the rail start end of the outer rail unit 22A. The protective cover 70 is attached to a position that covers the guide rail R inside the glass frame 14.

  As shown in FIGS. 34 and 35, the protective cover 70 is made of a transparent plastic material, and extends in a strip shape along the arc-shaped rail surface of the guide rail R. Support shafts 71, 71 are integrally formed at the lower end of the protective cover 70. As the support shafts 71 and 71 are fitted and rotated on the bearings 74 (see FIG. 33) of the outer rail unit 22A, the protective cover 70 is opened and closed on the front side of the game board 15.

  A spring plate 72 is formed at the lower end of the protective cover 70 between two parallel open slits. A locking claw 73 is formed at the tip of the spring plate 72 and in the vicinity of the opening / closing axis of the protective cover 70.

  FIG. 36 shows a state where the protective cover 70 is removed from the outer rail unit 22A. Bearings 74 and 74 are arranged at equal intervals with the support shafts 71 and 71 of the protective cover 70 at the protective cover mounting portion of the outer rail unit 22A. The bearings 74 and 74 have a bottomed cylindrical shape, and the support shafts 71 and 71 are inserted by being shifted in the axial direction from the open cylinder ends.

  A protrusion 75 is formed between the bearings 74 and 74. When the protective cover 70 is attached to the outer rail unit 22 </ b> A, the inclined surface of the protrusion 75 hits the locking claw 73 of the protective cover 70.

In the normal state, as shown in FIG. 37, the locking claw 73 has the end surface near the rail surface of the bulging portion 73 a (the lower right end surface in FIG. Keep it almost perpendicular to the surface.
When the upper end portion of the protective cover 70 is held by hand and opened to the outside, as shown in FIG. 37 (B), the bulging portion 73a rotates while shifting so as to rise up the inclined surface of the projection 75, and the spring plate 72 is moved. Bend. When the protective cover 70 is opened to a certain angle, the contact surface between the bulging portion 73a and the protrusion 75 is switched to release the flexure of the spring plate 72, and the end surface on the opposite side of the bulging portion 73a (FIG. 37A). The lower left end surface) hits the inclined surface of the protrusion 75, and the opening angle of the protective cover 70 is maintained (see FIG. 37C).

Thus, according to this embodiment, since the protective cover 70 is supported by the support shaft 71 so as to be opened and closed, the opening / closing operation is simplified. Further, since the opening / closing angle of the protective cover 70 is regulated by the locking claw 73, the rail surface can be easily cleaned with one hand while the protective cover 70 is opened.
Furthermore, by limiting the opening angle of the protective cover 70 to a range of less than 90 ° from the standing state, it is possible to cope with forgetting to close the protective cover 70. That is, in the above range, even if the glass frame 14 is tightened with the protective cover 70 opened, the protective cover 70 is pushed by the glass plate and returns to the standing state (FIG. 37A) by the spring effect of the spring plate 72. . As a result, maintenance of the gaming machine can be performed with peace of mind.

[Other invention 3: Detaching handle for game board]

[Other invention 4: Chamfering of rail unit]
The gaming machine according to the embodiment is configured such that the game board 15 is mounted by inserting the game board 15 into the opening of the main body frame 13 (game board mounting frame section 93) from the front of the main body frame 13. On the other hand, in the gaming machine of the above-described embodiment, the corner decoration constituting the front portion of the rail unit 22 is integrally provided on the base plate 21 of the gaming board 15.
If the corner decoration is integrally fixed to the base plate in this manner, the thickness of the corner decoration may be in the way, and it may be difficult to insert and attach the game board from the front of the main body frame. In particular, the corner decoration on the hinge side of a gaming machine tends to hit the frame surface of the main body frame, and tends to be an obstacle to the mounting operation.

The gaming machine of the present invention is a gaming machine having a configuration in which a gaming board is mounted by inserting a gaming board into the opening of the main body frame from the front of the main body frame,

A sufficient distance is maintained (see FIG. 43), and the locking groove 92 is easily fitted into the locking piece 94.

[Other invention 5: Press-fit pin storage structure of rail unit]
The rail unit having a plurality of press-fit pins as in the above embodiment, when the rail units are stacked, the press-fit pins hit the adjacent rail units and form a gap between the units. Is inconvenient.

  The gaming machine of the present invention is a gaming machine including a rail unit having a plurality of press-fit pins, and a storage hole that can store press-fit pins of other adjacent rail units on a unit surface opposite to the press-fit pins of the rail unit. It was set as the structure which provides.

According to such a configuration, when the rail units are stacked, by storing the press-fit pins in the storage holes of the overlapping rail units, the gap between the units is reduced. As a result, the rail units can be stacked in a compact manner, and handling such as transportation and storage becomes convenient.
Note that the present invention may be applied not only to the press-fit pin but also to other protruding portions such as a boss protruding on the rear surface of the rail unit.

In the present embodiment, the present invention is applied to the outer rail unit 22A. As shown in FIG. 6, four press-fit pins 32a to 32d are provided on the back surface of the outer rail unit 22A along the rail surface. Also, a boss B1 protrudes from the lower part of the unit.

As a result, there is no gap between the outer rail units 22A, and the outer rail units 22A can be transported and stored in a compact form.

[Other Invention 6: Rail Unit Locking Mechanism]
Conventionally, a plurality of divided rail units (outer rail unit, intermediate rail unit, and inner rail unit) are transported and stored in a state of being easily handled and assembled to a game board (base plate). However, it was troublesome to assemble the adjacent units on the game board (base plate) while matching their arc-shaped rail surfaces accurately so as not to hinder the ball from sliding and rolling.
Therefore, in the present invention shown in the above embodiment, in a gaming machine having a configuration in which a gaming area is partitioned by combining a plurality of divided rail units (outer rail unit 22A, intermediate rail unit 22B, and inner rail unit 22C). Of the divided rail units, at least two units (intermediate rail unit 22B, inner rail unit 22C) are rotatably supported.

  According to such a configuration, before the rail unit is assembled to the front surface of the game board (base plate), when the rail unit is transported, stored, etc., the units that are pivotally supported are closed to each other in a compact form. It can be folded in, and there is no trouble in transportation and storage. On the other hand, when the rail unit is assembled to the game board (base plate), if the units are rotated around the rotation axis, the rail unit can be immediately deployed so as to form a game area, In addition, the arc-shaped rail surfaces of adjacent units can be easily matched and assembled.

  In the above invention, when the rail unit pivotally supported is transported, stored, or the like, even if the units are kept in a closed state, rattling or gratting may occur. Further, when the rail unit is assembled to the game board (base plate), it is preferable that these rail surfaces (see FIG. 3) can be easily positioned in the deployment direction while the rail unit is deployed.

  Therefore, the gaming machine of the present invention is configured to pivotally support the rail unit divided into two or more, and the rail unit is formed with overlapping portions that overlap each other while sliding on each other. The lock claw and the lock hole are provided so as to fit each other when the rail unit is closed around the rotation axis and when the rail surfaces of the rail unit coincide.

According to such a configuration, when the units supported by the rotating shaft are closed, the overlapping portion is slid to fit the lock claw and the lock hole provided in the closed position in advance. Then, the units are locked while being closed, and handling such as transportation becomes easy.
When the rail unit is deployed, the rail surfaces of the units can be easily and accurately matched in the deployment direction by fitting the lock claw and the lock hole provided at the deployment position.

When a specific example is shown in the embodiment, the rail unit 22 of the gaming machine 10 is divided into an outer rail unit 22A, an intermediate rail unit 22B, and an inner rail unit 22C. Among these units, as shown in FIG. 45, the intermediate rail unit 22B and the inner rail unit 22C are pivotally supported by a connecting screw 26 (rotating shaft). The intermediate rail unit 22B and the inner rail unit 22C are formed with bosses 110 and 111 of the connecting screw 26, and these bosses 110 and 111 overlap each other.
As shown in FIG. 45, lock holes M1 and M2 are opened in the boss 110 of the intermediate rail unit 22B. On the other hand, on the boss 111 of the inner rail unit 22C, a lock claw 112 that can be fitted into the lock holes M1 and M2 protrudes downward in FIG. The lock holes M1 and M2 and the lock claw 112 are concentric with respect to the center of the connection screw 26.

  When closing the intermediate rail unit 22B and the inner rail unit 22C, the boss 110 and the boss 111 are slid so that the lock pawl 112 fits into the lock hole M2, as shown in FIG. At this time, as shown in FIG. 47, the intermediate rail unit 22B and the inner rail unit 22C are folded around the connecting screw 26, which is convenient for transportation and storage.

  On the other hand, when the inner rail unit 22C is rotated counterclockwise around the connecting screw 26 from the state shown in FIG. 46, the overlapping portions 110 and 111 slide and lock into the lock hole M1 as shown in FIG. The nail 112 is fitted. At the same time, the rail surfaces of the intermediate rail unit 22B and the inner rail unit 22C coincide.
