Description

  The present invention relates to a pachinko gaming machine in which each side end of an inner frame and a front frame is pivotably supported by a pivotal support portion provided on one side end of an outer frame so that the transparent plate is fixed to the front frame and the front frame. It is related with the fraud prevention member which can prevent effectively the fraud act performed by inserting a piano wire etc. in the game board surface from the clearance gap between.

The pachinko machine has an outer frame assembled to the island facility of the game hall, an inner frame that supports the game board and is pivotally supported on one side edge by the outer frame, and a transparent covering the front of the game board And a front frame (glass frame) that supports the panel (glass panel) and is pivotally supported by a shaft support portion provided on one side edge of the inner frame so that the one side edge is rotatable.
Conventionally, when the front frame is closed with respect to the inner frame that is attached to the outer frame, between the one side edge of the inner frame provided with the opening and closing shaft and the one side edge of the front frame. A fraudulent act is carried out in which an illegal device such as a piano wire or a cell board is inserted into the game area from the formed gap and interferes with a game ball or a board component to advance the game advantageously for the player.

In order to prevent such fraud, Patent Document 1 discloses a technique for preventing the insertion of a fraudulent instrument by disposing a fraud prevention piece made of a soft material between the inner rail and the glass surface. Has been.
However, with this conventional technology, it is only possible to prevent the insertion of unauthorized equipment only in the area where the inner rail is arranged, and the recent pachinko game where the board area has expanded with the increase in the size of the symbol display device In the machine, it was possible to insert a fraudulent instrument from an area where the inner rail was not arranged, which was insufficient to prevent fraud.
Further, in Patent Document 2, a rib having a U-shaped cross section is provided on the left end edge of the inner frame holding the game board, and an I shape is provided on the left end edge of the front frame holding the glass panel covering the game board. A fraud prevention structure is proposed in which when the front frame is closed against the inner frame, the I-shaped rib fits into the recess of the U-shaped rib to fill the gap between the two frames. Has been.
However, because the fixed surface of the U-shaped rib is located in the gap between the inner frame and the front frame, insert a fraudulent execution tool such as a bar or screwdriver through the gap and remove the rib from the inner frame to remove the illegal device. It was possible to newly form a gap to be inserted, which was not sufficient to prevent fraud.

By the way, conventionally, an act of illegally opening a winning opening on the game board surface by pressing an unauthorized device through a contact surface between a front frame and a glass panel attached and fixed to the back of the front frame has been performed. The portion of the contact surface between the front frame and the glass panel where such an illegal act is performed is located on the side opposite to the opening / closing axis, and cannot be handled by the conventional anti-fraud technology. It was.
That is, of the contact surface between the front frame and the glass panel, the end on the opening / closing axis side and the upper and lower sides are inserted into a fraudulent instrument by making a long contact length that is complicatedly bent stepwise or crank-shaped. However, the width of the other end edge opposite to the opening / closing axis is reduced because it is necessary to arrange a locking mechanism for locking between the glass panel edge and the front frame edge. Therefore, the width of the contact surface between the front frame and the glass panel is narrow, and it is easy to insert unauthorized equipment.

This will be explained based on a partial rear perspective view of the front frame of FIG. 13, a cross-sectional view of the front frame of FIG. 14, and a cross-sectional view of the main part of the front frame of FIG. The glass panel 110 is detachably fixed at several positions by a fixing lever 120 with the outer peripheral side front surface attached to the back surface. The front frame 100 is pivotally supported by a pivotal support portion having one side edge 101 provided on one side edge of the outer frame (not shown).
By assembling and fixing the outer peripheral side front surface of the glass panel 110 to the rear surface of the front frame, the opening of the front frame is closed by the glass panel. A sheet metal frame member 140 is annularly fixed to the rear side of the front frame, and a thick resin member 141 is annularly fixed to the front portion of the sheet metal frame member 140. The glass panel 110 is positioned and fixed by being supported on the outer peripheral edge by a stepped glass panel support surface formed on the inner peripheral surface of the resin member 141 arranged in an annular shape along the peripheral edge of the opening of the front frame. The lever 120 is fixed to the front frame by fastening.

  The glass panel 110 has a configuration in which two glass plates 111 are arranged so as to face each other with a predetermined gap G interposed therebetween, and the outer peripheral edge of each glass plate is held and integrated by an annular frame member 112 made of resin. The glass panel 110 is fixed by the fixing lever 120 provided on the front frame in a state where the outer periphery and the front surface of the glass panel 110 are attached to the rear surface of the front frame 100 (inner peripheral step surface of the resin member 141). As is apparent from FIG. 14, one side edge of the glass panel 110 penetrates deeply toward the one side edge (opening / closing axis side) 101 of the front frame, while the other side edge of the glass panel is the other side of the front frame. It terminates before the edge 102. This is because there is no obstacle at one side edge of the front frame, so there is little trouble even if one side edge of the glass panel is extended toward one side edge of the front frame. Since it is necessary to arrange a locking mechanism 105 for locking at the side edge 102, in order to avoid interference between the other edge of the glass panel and the locking mechanism, the other edge of the glass panel is locked. This is because it needs to be terminated before this. In this way, at one side edge of the front frame on the opening / closing axis side, a large contact area between the rear surface of the front frame and the glass panel can be secured, so the contact surface 130 has a stepped shape (crank shape) as shown in FIG. ) To prevent the insertion of unauthorized equipment. In addition, since the space on the opening and closing shaft side has a space, it is possible to adopt the tamper-proof structure disclosed in Patent Documents 1 and 2, but there is a patent on the other end edge 102 side. There is no room on the space to adopt the prevention structure of Document 2.

  On the other hand, on the other side edge 102 of the front frame where the space for supporting the glass panel is limited, as shown in FIG. 15, the contact surface 131 between the other side edge of the glass panel and the back of the front frame (resin member 141). Only has an L-shaped surface with a short contact length, and has a structure in which an unauthorized device can be easily inserted. That is, a resin member 141 supported by a sheet metal frame member 140 is fixed to a portion where the front frame supports the other edge of the glass panel, and an L-shaped contact surface 131 having an extremely short contact length is used. Since it only supports the edge of the glass panel, it is easy to press-in a fraudulent instrument such as a wire or a thin plate while deforming the elastic member 141 from the insertion direction indicated by the arrow D in FIG. It is possible to open a prize opening on the board and get a ball illegally.

As shown in each figure, the frame structure of the pachinko gaming machine 1 has a plate-like shaft support portion 3 protruding forward from the upper and lower ends of one side end (left end) 2a of the rectangular frame-shaped outer frame 2. A pivotal support 21 projecting forward from the upper and lower ends of one side end (left end) 20a of an inner frame (game board mounting frame) 20 that supports the game board 25, and a front frame that supports the glass panel 50 ( The inner frame 20 with respect to the outer frame 2 and the outer frame 2 by simultaneously supporting the supported portions 31 projecting forward from the upper and lower ends of one side end (left end) 30a of the glass frame 30) Each of the front frames 30 is supported to be openable and closable.
In this way, the pachinko gaming machine 1 to which the tamper-proof member 60 of the present invention is applied is configured to support the outer frame 2 having the pivot support 3 on one side and the game board 25 and rotate the one side by the pivot 3. The inner frame 20 that is pivotally supported and the glass panel (transparent panel) 50 covering the front of the game board are detachably supported, and the one end 30a is pivotally supported by the pivot support 3 so as to be rotatable. And a front frame 30.

A bulging portion 32 that bulges forward, a launch lever 33, and the like are provided at the lower portion of the front frame 30, and a basin portion 32a that stores a game ball is disposed in the bulge portion 32. This is means for launching a game ball in the tray 4.
The fraud prevention member 60 is made of a material that can be manufactured by injection molding, such as resin or rubber, and the outer peripheral edge of the glass panel 50 when the front outer periphery of the glass panel 50 is attached to the back of the front frame 30 and fixed. When a contact surface 37a into which a fraudulent instrument such as a wire or a thin plate can be inserted is formed between the rear surface of the front frame and the front frame (resin member 37), It is a means for preventing an unauthorized device from being inserted into the game board surface through the contact surface 37a and the gap 37b.
A glass panel 50 is detachably fixed at several positions by a fixing lever 35 on the back surface of the rectangular annular front frame 30 with the front surface on the outer peripheral side attached thereto.
By assembling and fixing the outer periphery of the glass panel 50 to the back surface of the front frame, the opening 30A of the front frame is closed by the glass panel. A sheet metal frame member 36 is annularly fixed to the back side of the front frame, and a thick resin member 37 is annularly fixed to the front portion of the sheet metal frame member 36 (FIGS. 10 and 11). reference).

That is, on the back surface of the front frame 30, a sheet metal frame member 36 disposed along the outer peripheral edge of the glass panel (transparent panel) 50 fixed thereto, and a resin member disposed along the sheet metal frame member 37, a glass panel support frame (transparent panel support frame) P is formed. The gap 37b is formed between the glass panel support frame P and the glass panel 50, and a first locked portion 36a ′ and a second locked portion 36a ″ described later are formed on a sheet metal frame material. Is provided.
The glass panel 50 is positioned by supporting the outer peripheral edge and the front surface by a stepped glass panel support surface 37a formed on the inner peripheral surface of the resin member 37 arranged in a ring shape along the opening peripheral edge of the front frame. Then, it is fixed to the front frame by fastening the fixing lever 35.
The glass panel 50 is configured by holding and integrating the outer peripheral edges of each glass plate with a resin-made annular frame member 52 and a packing 53 in a state where two glass plates 51 are arranged to face each other with a predetermined gap G interposed therebetween. And is fixed by a fixing lever 35 provided on the front frame in a state where the front surface along the outer periphery of the glass panel 50 is attached to the rear surface of the front frame 30 (inner peripheral step surface 37a of the resin member 37). .

As is apparent from FIG. 10, one side edge of the glass panel 50 penetrates deeply toward one side edge (opening / closing axis side) 30a of the front frame, while the other side edge of the glass panel is the other side of the front frame. It terminates in front of the edge 30b. This is because there is no obstacle at one side edge of the front frame, so that one side edge of the glass panel can be extended toward one side edge of the front frame, while the other side of the front frame Since it is necessary to secure a space for disposing the locking mechanism 40 for locking at the end edge 30b, in order to avoid interference between the other end edge of the glass panel and the lock mechanism, the other end edge of the glass panel is provided. This is because it needs to be terminated before the lock mechanism 40.
Since the length in the thickness direction (length in the front-rear direction) of the contact surface between the rear surface of the front frame and the glass panel can be secured sufficiently long at one side edge of the opening / closing axis side of the front frame, the contact surface is shown in FIG. As shown in FIG. 4, it is possible to prevent the unauthorized device from being inserted by forming a stepped shape (crank shape). Further, since there is a space in the portion on the opening / closing axis side, it is possible to adopt a protrusion or other tamper-proof structure, but a tamper-proof structure such as a protrusion on the other end edge 30b side. There is no room on the space to adopt.

Further, on the other side edge 30b of the front frame where the space for supporting the glass panel is limited, as shown in FIG. 11, the contact surface 37a between the other side edge of the glass panel and the front frame back surface (resin member 37). Is merely an L-shaped surface with a short contact length in the thickness direction, and it is easy to insert an unauthorized device. That is, a resin member 37 supported by a sheet metal frame member 36 is fixed to a portion where the front frame supports the other side edge of the glass panel, and an L-shaped contact surface 37a having a very short contact length. Since it only supports the edge of the glass panel, it is easy to press-fit a fraudulent instrument 70 such as a wire or a thin plate while deforming the resin member 37 from the insertion direction indicated by the arrow D in FIG. Therefore, it is possible to open a winning opening on the game board surface and obtain a ball illegally.
In contrast, in the present invention, a gap 37b formed between the rear face of the front frame and one end edge of the glass panel 50, in other words, the rear face side communicating with the contact face 37a between the sheet metal frame member 36 and the resin member 37. A fraud prevention member 60 made of resin or rubber is attached and fixed to the gap 37b of the gap 37b so that it cannot be removed by the fraudulent instrument 70 press-fitted into the contact surface 37a from the direction of arrow D. Cheating can be effectively prevented.

The fraud prevention member 60 includes a fitting projection 61 fitted in a gap 37b formed between the rear face of the front frame (inner circumferential surface of the resin member) and the outer peripheral edge of the glass panel, and a base of the fitting projection 61. A base portion 62 that is integrated with the end portion and is exposed to the back side when the fitting protrusion is fitted into the gap, and a locked portion 37c that protrudes from the fitting protrusion 61 and is within the gap 37b. And a locking projection 63 for stopping. Furthermore, a locking piece 64 folded back in a substantially U shape extends from the tip of the base portion 62 (FIG. 8).
When the fitting protrusion 61 is fitted in the gap 37b, the gap 37b is closed by the cooperation of the fitting protrusion 61 and the base portion 62, and an unauthorized device is prevented from entering the game board surface side. It is configured.
The sheet metal frame member 36 is provided with a locked piece 36a extending to the outer position of the gap 37b, and a first locked part 36a is provided at the bottom (the end near the gap 37b) of the locked piece 36a. 'And a second locked portion 36a "are provided at the tip of the locked piece 36a (Fig. 11).

When fitting protrusion 61 of fraud prevention member 60 is fitted in gap 37b, locking protrusion 63 engages with first locked portion 36a 'and prevents fraud prevention member from falling out of the gap. To do. Further, the engaging piece 64 of the tamper-proof member engages with the second locked portion 36a ″, thereby increasing the engaging force with the sheet metal frame member 36, and stably fixing the tamper-proof member to the front frame. (FIG. 9).
When the fitting projection 61 of the fraud prevention member 60 is fitted into the gap 37b, the fitting projection 61 including the locking projection 63 is fitted into the gap 37b, while the locking projection 63 is After engaging with the first locked portion 36a ′, it is difficult to remove the tamper-proof member 60 from the gap. If the lock mechanism is illegally released to open the front frame and the anti-fraud member 60 is to be removed, if the strength and structure are devised so that the locking projection 63 is damaged, This leaves a trace of unauthorized removal of the anti-fraud member, making it possible to discover fraud.

Alternatively, when the front frame is in a closed state, a fraudulent instrument is press-fitted from the contact surface 37a to press the fraud prevention member 60 and fall off from the gap 37b, or a part of the fraud prevention member is damaged, Although it is possible that the illegal device causes the illegal device to reach the winning opening on the game board surface, in this case, if the locking protrusion 63 is broken when the anti-fraud member is removed, a trace of the illegal activity may be left. Is possible.
In addition, when the front frame 30 is closed to the inner frame 20 in a state where the fraud preventing member 60 is set on the front frame 30 as shown in FIG. 12, the base portion 62 of the fraud preventing member 60 is set on the inner frame 20. When the front frame 30 is closed, a part of the game board 25 or a part of the board surface, in this example, is configured to be in pressure contact with the front surface of the protrusion 26 (back rubber support part) provided on the outer periphery of the game board. The tamper-proof member can be held between the front frame and the protrusion 26 with pressure. For this reason, even if it tries to press-fit a fraudulent instrument from the contact surface 37a and remove a fraud prevention member, such an attempt cannot be completed.

As described above, when a fraudulent instrument can be inserted from the contact surface between the glass panel and the front frame of the pachinko gaming machine, the anti-fraud member is attached in advance to the clearance provided on the back side of the contact surface. By blocking the intrusion route, it is possible to effectively prevent the press-fitting of an unauthorized device. In particular, since the fraudulent instrument is locked by the locked portion provided on the front frame side, even if it is attempted to remove the fraud prevention member by the fraudulent instrument, it cannot be removed. In addition, when the anti-fraud member is separated from the gap by pressure from the surface side by an improper device, the engagement protrusion can be broken to leave a trace of fraudulent acts. The venue side can take quick measures. In addition, the tamper-proofing member is more difficult to be detached or damaged by pressing the tamper-proofing member with a game board or a board surface component provided inside the front frame.
Moreover, this tamper-proof member is a low-cost resin molded product, and has the advantage that a crime prevention effect can be exhibited by simply mounting it on the front frame of an existing pachinko gaming machine.
Further, the place where the tamper-proof member can be mounted is not limited to the edge facing the opening / closing shaft described in the above embodiment, but may be any place where a tampering tool can be press-fitted.
The fraud prevention member of the present invention can be applied not only to the front frame (glass frame) of pachinko gaming machines but also to general gaming machines having glass frames.
