Description

  The present invention relates to a fraud prevention structure for a pachinko machine that mainly prevents fraud using a wire such as a piano wire.

Conventionally, as a technology for preventing fraud by inserting a fraudulent execution tool such as a piano wire through the gap between the front frame (glass frame) of the pachinko machine and the inner frame and guiding the game ball to the winning mouth, patent literature There is an invention described in 1.
In this method, an anti-fraud piece made of a soft material of an anti-fraud member attached to the side surface of the inner rail provided on the game board surface is brought into close contact with the glass surface.
JP-A-8-164248

However, although the conventional technology has the advantage that the fraud prevention piece made of a soft material is in close contact with the glass surface and can reliably prevent the fraud execution tool from being inserted from the gap, the fraud execution tool insertion prevention function In the inner rail, it works only in a range where the tamper-proof member is attached, that is, only in a region where the inner rail is arranged.
On the other hand, recently, with the increase in the size of the symbol display device provided in the game area, the game board has also increased in size, and therefore the front frame has increased in size as well. For this reason, the axial support interval (hinge interval) of the front frame becomes longer and the gap becomes longer, which makes it easy to perform fraudulent actions.
In addition, in the above prior art, because the anti-tampering piece is attached to the side surface of the inner rail, it is compatible with the model and has low versatility, and its configuration and assembly cost are not small. Improvement was an issue.

  The present invention has been made in view of the problems as described above, and the function of preventing the insertion of the fraudulent execution tool is not limited to the arrangement area of the inner rail, but works in a wider area, and can be realized at low cost and repaired. Another object of the present invention is to provide a fraud prevention structure of a pachinko machine that can be easily performed and has a high defense effect against the destructive action to the insertion prevention function of the fraud execution tool.

Means for solving the above problems will be described below.
Each means is classified into sections, each section is given a number, and the number of other sections is quoted as necessary. This is for facilitating the understanding of the present invention, and the technical features described in the present specification are not limited to those described in the following sections.
Of the following means, (1) corresponds to claim 1 and (2) corresponds to claim 2. In each means, the operation and the like will be described as necessary.

(1) An inner frame to which a game board attached with an outer frame and having a game area is mounted; and a front frame whose side ends are pivotally supported so as to open and close the game board mounting area of the inner frame; In the pachinko machine comprising the front frame, the gap between the shaft support side end portion of the front frame and the side end portion of the inner frame adjacent to the shaft support side end portion overlaps when the front frame is closed. A frame-shaped barrier material having a predetermined strength that forms a barrier covering the entire range in the vertical direction is provided on each of the shaft support side end portion of the front frame and the side end portion of the inner frame. Anti-fraud structure for pachinko machines.
The material of the frame-shaped barrier material is not limited as long as it has a predetermined strength, but basically, a metal material (frame-shaped barrier metal fitting) such as an iron material is used.
The predetermined strength refers to a strength that is not easily bent by “keep-opening (bending)” using a bar or the like, in particular, rigidity when a barrier is formed by overlapping.
Each frame-like barrier material is preferably formed as a whole, but may be divided into a plurality.
(2) A front frame side frame-shaped barrier material and an inner frame side frame-shaped barrier material each having a U-shaped cross section, and the front frame side when the front frame is closed In a state where any one of the opposing pieces of the U-shaped portion of the frame-shaped barrier material enters into the opening of the U-shaped portion of the inner frame-side barrier material, both the frame-shaped barrier materials overlap and The pachinko machine fraud prevention structure according to item (1), wherein a barrier is formed.
If the barrier is formed with a U-shaped front frame side frame-shaped barrier material and an inner frame side frame-shaped barrier material, it is almost impossible to allow the cheating execution tool to enter the game area through this barrier portion, In addition, the strength against “pricking (bending)” using a bar or the like is remarkably increased.
Of course, the U-shape includes a substantially U-shape.

In the invention described in (1), the gap between the shaft support side end portion of the front frame and the side end portion of the inner frame (shaft support side gap) overlaps when the front frame is closed. A frame-shaped barrier material having a predetermined strength covering the range was provided on each of the end portion on the shaft support side and the side end portion of the inner frame of the front frame. In other words, when the fraudulent execution tool tries to enter the game area from the outside of the pivot support side gap, the frame-shaped barrier material is caused to function as a barrier over the forefront and the maximum area. Therefore, the effect of preventing the insertion of the fraudulent execution tool can be demonstrated more effectively and in a wider range than the conventional technology.
Further, the frame-like barrier material is basically formed in a simple shape such as a belt-like shape, and the frame-like barrier material only needs to be fixed to the front frame and the inner frame. It is highly versatile and can be realized at low cost, and it can be easily repaired (replaced).
Further, the frame-shaped barrier material increases in strength because the two overlap each other when the front frame is closed to form a barrier. Therefore, a destructive action to the insertion preventing function of the cheating execution tool, specifically, “pry opening (bending)” performed by inserting a bar tip into the shaft support side gap in order to insert the cheating execution tool. The defense effect against such as is increased.
According to the invention described in the item (2), it is possible to maximize the effect of preventing the insertion of the fraud executor and to further enhance the effect of preventing the destruction to the function of preventing the execution of the fraud executor. .

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol shows the same or an equivalent part between each figure.
FIG. 1 is a front view showing an embodiment of a pachinko machine to which a fraud prevention structure according to the present invention is applied, and FIG. 2 is a perspective view schematically showing a state in which an inner frame and a front frame of the pachinko machine are opened.
In these drawings, reference numeral 12 denotes an outer frame 2 used for attachment to a pachinko machine installation location called an island.
On the front side of the outer frame 12, there is a substantially frame-shaped inner frame 14 having a window portion (game board mounting area described later). The right side is attached so that it can be opened and closed.

Further, on the front side of the inner frame 14, the front frame 20 is pivotally supported by the upper left and right sides of the inner frame 14 on the left side (right side in FIG. 2) of FIG. In Fig. 2, the left side) is attached to be freely opened and closed. The front frame 20 is provided with a translucent plate frame on which a translucent plate (translucent plate) is attached, and usually a glass plate frame 18 on which a transparent glass plate 16 is attached.
The front frame 20 and the inner frame 14 can be locked by a locking device (cylinder lock) 22 provided below the right side of the inner frame 14.

  Below the front frame 20 is a ball that stores award balls and rental balls paid out from a prize ball payout device (not shown) through a prize ball payout outlet 23 and guides them to a ball launching device (not shown). A dish unit 26 including a dish part 24 is attached to the inner frame 14 so as to be openable and closable on the left side. An ashtray 28 is attached to the left side and a firing handle 30 is attached to the right side at the lower front portion of the dish unit 26. The launch handle 30 is a handle for causing the game ball to be launched from the above-described ball launcher and for controlling the launch intensity.

A game board 32 is attached to the window portion of the inner frame 14 so as to close the window portion. In the present embodiment, the game board 32 is detachably attached to the window portion (can be replaced).
The game board 32 has a sheet-like cell 34 made of synthetic resin attached to the surface of a plywood board 33, and the board surface 32a is surrounded by an outer rail 36, an inner rail 37, and rail decorations 38, 39. A circular game area 40 is formed.

The game area 40 is provided with game area components such as a symbol display device 42, a big prize opening 44, a start prize opening 46, a general prize opening 48, a windmill 50, or side decorations 52a and 52b. In addition to the game area components, an out port 54 is disposed at the lowest position of the game area 40 and a large number of game nails (not shown) are driven therein.
At least the game area 40 of the board surface 32a can be seen through the transparent glass plate 16 from the front side of the front frame 20 (the front side of the pachinko machine) when the front frame 20 is closed to the inner frame 14.

  The front frame 20 is provided with a decoration 61 whose front surface is covered with a translucent resin plate in a state of protruding frontward (player side) at a position surrounding the periphery of the transparent glass plate 16. In the decoration 61, speakers 62 for outputting game sound effects (including synthesized sounds) are disposed, and lamps (not shown) such as three-color LEDs are disposed at a plurality of locations.

In addition, the pachinko machine of this embodiment is a model which arrange | positions a ball | bowl launcher on the lower left side of the game board 32, and discharges a game ball upward. To this ball launcher, the game balls stored in the ball tray portion 24 of the tray unit 26 are arranged in a line and supplied one by one. The game ball supplied to the ball launching device is launched from the ball launching device by a turning operation of the launching handle 30 in the clockwise direction by the player, guided by the rails 36 and 37, and sent into the game area 40.
The game balls sent into the game area 40 flow down in the game area 40 while colliding with obstacles such as game nails and windmills 50, and in the middle, the general winning port 48, the start winning port 46 or the big winning port. The game balls that won 44 and did not win are finally collected from the outlet 54.

  The number of winning balls to be paid out to the ball tray section 24 differs depending on whether the game ball is won by the general winning port 48, the starting winning port 46, or the large winning port 44. For example, 5 are set for the general winning opening 48 and the starting winning opening 46, 15 are set for the large winning opening 44, and the number of prize balls to be paid out is set to be awarded to the large winning opening 44. There are many.

  When the game ball wins the start winning opening 46, the symbol display device 42 starts displaying the symbols in a variable manner. If the symbol (stop symbol) when the predetermined time has passed after the start of fluctuation is a big hit, the big prize opening 44 is opened. The large winning opening 44 has a wide opening width and is repeated a plurality of times, such as up to 15 times if a predetermined condition is satisfied, so the number of winning balls obtained during this time is significantly larger than the case where a big hit is not made Become.

  The precondition that is a big win is that the game ball wins the start winning opening 46, and the winning to the starting winning opening 46 is often targeted for fraud. In addition, since cheating is performed by allowing the cheating execution tool to enter the game area 40, the cheating execution tool is inserted through the gap between the inner frame 14 and the front frame 20. This gap occurs when the front frame 20 is viewed from the front, that is, in FIG. 1, respectively, on the upper and lower sides and the left and right sides of the front frame 20. Of these, it is difficult to insert the cheating agent from the upper gap. It is conspicuous and the insertion work from the lower gap or the right gap is difficult due to the structure of the pachinko machine at that portion. Therefore, the cheating execution tool is often inserted through the gap 80 on the left side (the pivot support side) of the front frame 20, and winning in the general winning opening 48 closest to the gap 80 is also targeted for cheating. There are many cases.

An embodiment of a structure for preventing fraud in such a pachinko machine (fraud prevention structure) will be described in detail below.
The hatched portion 70 in FIG. 2 indicates the arrangement position of the frame-shaped barrier material that prevents the intrusion of an improper act such as a piano wire, and FIG. 3 shows an arrangement example of the frame-shaped barrier materials 71 and 72 in this embodiment. Show.
FIG. 3 shows the embodiment with the front frame 20 removed from the inner frame 14 in order to make the present embodiment easier to understand, but actually the front frame 20 can be opened and closed to the inner frame 14 as shown in FIG. Is attached. 3 is a pin that projects from the upper end surface of the left side portion (the right side portion in FIG. 3) of the front frame 20 and pivotally supports the front frame 20 on the inner frame 14 at the top. The glass plate frame 18 (transparent glass plate 16) attached to the back surface of the front frame 20 is not shown.

As shown in FIG. 3, the frame-shaped barrier members 71, 72 are on the left side of the front frame 20 in the gap between the inner frame 14 and the front frame 20, that is, between the end portions on the shaft support side of the front frame 20 and the inner frame 14. (Refer to FIG. 2, hereinafter, this gap is referred to as a shaft support side gap).
Specifically, the frame-shaped barrier member 71 is fixed to a shaft support side end (the left end as viewed from the front, the right end in FIGS. 2 and 3) of the front frame rear surface. The frame-shaped barrier member 72 is fixed to the inner surface of the barrier member mounting plate portion 14 a formed at the left end of the inner frame 14, specifically, the left end of the inner frame 14. When the strength of the barrier material mounting plate portion 14a is small, the barrier material mounting plate portion 14a is positioned on the inner surface of the barrier material mounting plate portion 14a and fixed to the left end portion of the front surface of the inner frame via a connector (not shown).
The length L1 of the frame-shaped barrier members 71 and 72 is equal to or longer than the total length of the pivot support side gap, and in this embodiment, is substantially equal to the total length.

As will be described in detail later, the frame-shaped barrier members 71 and 72 overlap each other when the front frame 20 is closed, and form a barrier that covers the axial support side gap from the inside to the entire vertical range. Hereinafter, these will be described with reference to FIGS.
4 shows a frame-like barrier material on the front frame side (hereinafter referred to as a front frame-side frame-like barrier material) 71, and FIG. 5 shows a frame-like barrier material on the inner frame 14 side (hereinafter referred to as an inner-frame-side frame-like barrier material). 72) 72.
The front frame side frame-shaped barrier material 71 and the inner frame side frame-shaped barrier material 72 are both formed to have a substantially U-shaped portion (a U-shaped portion) in cross section.
The front frame side frame-shaped barrier material 71 and the inner frame side frame-shaped barrier material 72 are U-shaped as shown in FIG. 3 when the front frame 20 (see FIG. 3) is closed. In a state in which any one of the pair of opposing pieces enters the opening of the U-shaped portion of the inner frame side frame-shaped barrier member 72, the two frame-shaped barrier members 71 and 72 overlap to form the barrier. To do.

As shown in FIG. 5, the inner frame side frame-shaped barrier member 72 is screwed to the inner frame 14 by screwing a screw (not shown) into the bottom piece of the U-shaped portion (one piece connecting a pair of opposing pieces). Is done. A circle 51 in FIG. 5 indicates a screwing position.
The front frame side barrier member 71 cannot be screwed to the front frame 20 at the same position as the inner frame side barrier member 72. This is because the direction of the opening of the U-shaped portion of the front frame side barrier member 71 is not appropriate for forming the barrier.
Therefore, in this embodiment, as shown in FIG. 4, the front frame side frame-shaped barrier member 71 is divided into a front frame side frame-shaped barrier member 71a having a substantially crank-shaped cross section and an L-shaped front frame side frame-shaped barrier member. 71b is combined and formed as shown. According to this configuration, after the crank-shaped front frame-side frame-shaped barrier member 71a is screwed to the back surface of the front frame 20, the front-frame-side frame-shaped barrier member 71a is L-shaped and the front-frame-side frame-shaped barrier member 71b. By screwing, the front frame side frame-shaped barrier member 71 is screwed to the rear surface of the front frame. That is, the front frame side frame-shaped barrier material 71 can be easily screwed to the rear surface of the front frame. A circle 41 in FIG. 4 indicates a screwing position.

The front frame-side frame-shaped barrier material 71 and the inner frame-side frame-shaped barrier material 72 are such that the cheating execution tool (piano wire or the like) tries to enter the game area 40 (see FIG. 3) from the outside of the pivot support side gap. In some cases, it functions as a barrier at the forefront. Further, the front frame side frame-like barrier material 71 and the inner frame side frame-like barrier material 72 are formed by causing the bar tip to enter the support side gap when the barrier is formed. It is also required to be able to protect against the “peeling (bending)” of the part. Therefore, the front frame side frame-like barrier material 71 and the inner frame side frame-like barrier material 72 can resist the advance input such as pushing and pushing of the cheating execution tool, that is, without being broken or punched, In addition, the material, thickness, and the like are selected so as to have strength, particularly rigidity, capable of preventing the above-described “pricking (bending)”.
In the present embodiment, the front frame side frame-shaped barrier material 71 and the inner frame side frame-shaped barrier material 72 are made of a metal material such as an iron material, and have a U-shaped portion as described above. Therefore, even if it is not too thick, the strength is increased.

  In the example shown in FIG. 3, one front frame side frame-shaped barrier member 71 and one inner frame side frame-shaped barrier material 72 each cover the entire length in the vertical direction of the shaft support side gap. May be divided into a plurality of pieces in the vertical direction so as to cover the entire length in the vertical direction of the shaft support side gap as a whole.

6 to 10 show the inner frame-side frame-like barrier material from the state in which the front frame 20 is opened approximately 90 ° to the inner frame 14 (FIG. 6) to the state in which the front frame 20 is closed at 0 ° (FIG. 10). FIG. 7 is a diagram showing the positions and orientations of a front frame side frame-shaped barrier member 71 with respect to 72 from above. 7, 8, and 9 show an aspect in which the front frame 20 is opened with respect to the inner frame 14 in the order of approximately 45 °, 15 °, and 5 °. An arrow A in each figure indicates the rotation direction of the front frame 20 (front frame side frame-shaped barrier member 71).
As can be seen from FIG. 10, when the front frame 20 is closed, one of a pair of opposed pieces of the U-shaped portion of the front frame side frame-shaped barrier member 71, in this embodiment, the front frame side frame-shaped barrier member 71 b. Enters the opening of the U-shaped portion of the inner frame side frame-shaped barrier member 72. That is, the front frame side frame-shaped barrier material 71 and the inner frame side frame-shaped barrier material 72 are overlapped to form a barrier 73 (see FIG. 11). Since the front frame side frame-shaped barrier member 71 and the inner frame side frame-shaped barrier material 72 have the length L1 substantially equal to the entire length of the shaft support side gap as described above, the barrier 73 is formed in the vertical direction of the shaft support side gap. The entire range will be covered.

According to the embodiment described above, when the fraudulent execution tool attempts to enter the game area 40 (see FIG. 3) from the outside of the pivot support side gap, the forefront and the maximum area are covered. Since the front frame side frame-shaped barrier material 71 and the inner frame side frame-shaped barrier material 72 are provided so as to become the barrier 73 (see FIGS. 10 and 11), the effect of preventing the insertion of the fraudulent execution tool is achieved in the prior art. Compared to effective and wide range.
In addition, the front frame side frame-shaped barrier material 71 and the inner frame side frame-shaped barrier material 72 are formed in a simple shape and only need to be fixed to the front frame 20 and the inner frame 14, so that the anti-fraud structure is highly versatile. In addition, it can be realized at low cost and can be easily repaired (replaced).
Further, the strength of the front frame side frame-shaped barrier material 71 and the inner frame side frame-shaped barrier material 72 is increased because they overlap to form the barrier 73 when the front frame 20 is closed. Therefore, the destructive action to the insertion prevention function of the fraudulent execution tool, specifically, the anti-brushing effect against “pricking (bending)” performed by inserting the tip of the bar into the shaft support side gap is increased.
