Description

  The present invention relates to a gaming machine, and more particularly to a mechanism for attaching a front frame to an inner frame so as to be openable and closable.

  In general, a gaming machine represented by a pachinko machine or a slot machine using a game ball (or medal) as a game medium is attached to an outer frame that forms an outer frame of the machine body, and is attachable to and removable from the outer frame. And a front frame. In such a gaming machine, a mechanism (hinge) that allows the front frame to be attached and detached and opened and closed is provided to be exposed to the outside of the gaming machine. In addition, in order to easily and smoothly open and close the front frame, flexibility is provided between the hinge members in advance, so that a slight rattling occurs even when the front frame is closed. It has become.

  However, the backlash of the front frame in the closed state causes the front frame to be lifted forcibly to create a gap between the outer frame, and an unauthorized device is inserted from the gap to illegally operate the device in the gaming machine. It can cause fraud. In light of the fact that such fraud is performed, in recent years, a gaming machine has been proposed that strengthens the unity with the outer frame when the front frame is closed and restricts the upward movement of the front frame ( For example, see Patent Document 1).

The gaming machine described in Patent Document 1 has hinged members at the lower part of the outer frame and the lower part of the front frame, respectively, and both of them can be rotated via a support shaft. In addition, the outer frame side hinge member has a locking claw piece, and the front frame side hinge member has an engagement recess. It is to be locked to. Thereby, since unity with an outer frame becomes strong, the upward movement of a front frame can be controlled.
Japanese Patent No. 3634905 (FIG. 7 etc.)

  However, in the gaming machine described in Patent Document 1, an instrument such as a flathead screwdriver is inserted into the gap between the outer frame side hinge member and the front frame side hinge member to deform the front frame side hinge member. Further, by removing the hinge member on the front frame side from the support shaft, there is a possibility that a gap is formed between the front frame and the outer frame so that an illegal instrument can be inserted. In this case, the engaging claw pieces and the engaging recesses do not function, so that the above-described fraud cannot be prevented.

  Further, in recent gaming machines, various effects are performed to improve the interest of the player, but since complicated control is required for the realization thereof, the control device tends to be heavy. In particular, when the gaming machine is a slot machine, since the control device is provided on the front frame side, the front frame becomes heavier with the attachment of the control device, which may hinder the opening and closing of the front frame. Therefore, the thickness of each member of the hinge is reduced to reduce the weight of the gaming machine, but on the other hand, when the above equipment is inserted, the hinge member tends to bend, so the above fraudulent act May be easily done.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a gaming machine that can surely prevent fraudulent acts caused by creating a gap between the frames so that a fraudulent instrument can be inserted. It is in.

In order to solve the above-mentioned problem, the invention according to claim 1 is provided with a first frame provided with a first hinge part and a second hinge part corresponding to the first hinge part. In the gaming machine including the second frame to which the first frame can be opened and closed, the second hinge part includes an attachment piece attached to the second frame, and an end of the attachment piece. a flat base piece projecting perpendicularly from parts, provided on the base piece, said first hinged portion and a support shaft you rotatably supported, said first hinged portion, said first A vertical frame piece that is attached to one frame and extends in the vertical direction of the first frame , projects vertically from an end of the vertical frame piece, is arranged in parallel with the base piece, and A flat-plate-shaped hinge arranged so as to overlap the upper surface side of the base piece when the frame of the base is closed A receiving piece provided to the hinge receiving piece, the support shaft and a hole portion that is inserted into and supported on at least one of said base piece and said hinge receiving piece, the outer peripheral edge of the base piece or the hinge receiving piece A folded piece is formed so that at least its tip is positioned above the upper surface of the base piece or below the lower surface of the hinge receiving piece, and the support shaft is inserted and supported in the hole. Thus, when the first frame is supported by the second frame and the first frame is closed, the tip of the folded piece is located on the upper surface of the hinge receiving piece and the lower surface of the hinge receiving piece . A gist of the gaming machine is characterized in that it is arranged in the vicinity of at least one and a gap between the base piece and the hinge receiving piece is covered by the folded piece .

Therefore, according to the first aspect of the present invention, even if an instrument is inserted into the gap between the base portion (base piece) and the hinge receiving portion (hinge receiving piece) to deform the hinge receiving portion or the base portion, the base Since the lower surface of the part or the upper surface of the hinge receiving part abuts against the tip of the folded part (folded piece) , the hinge receiving part or the base part is deformed to support the supported part (hole part) (support) it is not possible to release the insertion state of the axis). Therefore, a gap is formed between the first frame and the second frame so that an illegal device can be inserted, and an illegal act performed by inserting the illegal device into the gaming machine from the gap can be reliably prevented.

  In addition, the material forming the first butterfly part and the second hinge part is not particularly limited, and a metal material, a resin material, or the like can be used, but in order to prevent deformation when the instrument is inserted, It is preferable to use a metal material having high strength. Moreover, although the formation method of a 1st butterfly part and a 2nd butterfly part is not specifically limited, If it forms by bending a metal plate, formation of a 1st butterfly part and a 2nd butterfly part will become easy. .

In the first aspect of the present invention, since the hole is provided in the first hinge part attached to the first frame, the weight of the first frame is reduced by the amount corresponding to the hole. Can do. That is, by reducing the weight of the first frame on which the control device or the like is provided, the possibility of hindering the opening and closing of the first frame can be reduced. Further, because not support shaft is provided which protrudes to the second hinged portion attached to the second frame, supporting the first frame when mounting the second frame, the hole with the aim Easy to insert the shaft.

By the way, since fraudulent acts are performed with as little conspicuousness as possible (for example, it is not necessary to extend their hands or stand up), there is a high possibility that the lower side of the gaming machine is targeted. . Therefore, it is preferable that the hinge receiving portion is provided at a lower end of the vertical frame portion (vertical frame piece) . In this way, it is difficult to insert the instrument into a part that is easily targeted (the gap between the hinge receiving part at the lower end of the vertical frame part and the base part), so that illegal acts can be effectively prevented. . In addition, the said hinge receiving part may be provided in the upper end of the said vertical frame part, and may be provided in the upper end and lower end of the said vertical frame part, respectively. In addition, when the said hinge receiving part is provided in the upper end and lower end of a vertical frame part, it is preferable to provide a base part in the upper end side and lower end side of a vertical frame part. Thereby, since a folding | returning part is provided in the upper end side and lower end side of a vertical frame part, an illegal act can be prevented further.

  The folded portion may be formed on the base portion or may be formed on the hinge receiving portion. If the folded portion is formed on both the base portion and the hinge receiving portion, the total area of contact between the tip portion of the folded portion and the base portion (or the hinge receiving portion) is increased. It is possible to more reliably prevent the act of inserting the instrument into the gap between the receiving part and deforming the hinge receiving part or the base part. And since the clearance gap between a base part and a hinge receiving part can be covered in more places, the insertion of the instrument to the clearance gap between a base part and a hinge receiving part can be prevented more reliably.

  In addition, the folded portion may be provided so as to be visible by being exposed to the outside of the gaming machine, or may be provided so as not to be visible by being shaded by other members. If the folded portion is provided so as to be visible, since the presence of the folded portion can be shown and the illegal act can be praised, the illegal act can be prevented in advance. On the other hand, if the folded portion is provided so as not to be visually recognized, the folded portion is less likely to become an obstacle.

  Furthermore, the width of the folded portion (the length of the connecting portion between the folded portion and the base portion or the length of the connecting portion between the folded portion and the hinge receiving portion) is preferably set as large as possible. . In this way, the contact area between the tip of the folded portion and the base portion (or the hinge receiving portion) is increased, so that an instrument is inserted into the gap between the base portion and the hinge receiving portion and the hinge receiving portion or the base portion is inserted. The action of deforming can be prevented more reliably. And since the clearance gap between a base part and a hinge receiving part can be covered over a wider range, insertion of the instrument to the clearance gap between a base part and a hinge receiving part can be prevented more reliably. However, if the width of the folded portion is too large, there is a high possibility of becoming an obstacle when the first butterfly portion is rotated or when the first frame is attached to the second frame. Therefore, it is preferable that the width of the folded portion is set as large as possible without causing an obstacle.

When the folded portion is formed on the base portion, it is preferable that the distance between the tip portion of the folded portion and the upper surface of the hinge receiving portion becomes wider toward the tip. If it does in this way, it will become easy to guide a hinge receiving part between the tip part of a return part, and a base part. On the other hand, when the folded portion is formed in the hinge receiving portion, it is preferable that the distance between the distal end portion of the folded portion and the upper surface of the base portion becomes wider toward the distal end. If it does in this way, it will become easy to guide a base part between the tip part of a return part, and a hinge receiving part.
According to a second aspect of the present invention, in the first aspect, the hinge receiving piece is bent vertically from an upper hinge receiving piece bent vertically from an upper end portion of the vertical frame piece and from a lower end portion of the vertical frame piece. The upper hinge receiving piece and the lower hinge receiving piece protruding in the same direction, the second hinge part being attached to the upper part of the front surface of the second frame, A lower second hinge part attached to the lower part of the front surface of the second frame, wherein the upper second hinge part is perpendicular to the upper attachment piece as the attachment piece and the upper end of the upper attachment piece An upper base piece that is the bent base piece, and the lower second hinge part is a lower attachment piece that is the attachment piece, and the base piece that is bent vertically from the lower end of the lower attachment piece. A lower base piece, the upper base piece and At least one of the upper hinge receiving piece protrudes from the outer peripheral edge of the upper base piece or the upper hinge receiving piece, and the tip thereof is located above the upper surface of the upper base piece or below the lower surface of the upper hinge receiving piece. An upper folded piece which is the folded piece folded back is formed, and at least one of the lower base piece and the lower hinge receiving piece has an outer peripheral edge of the lower base piece or the lower hinge receiving piece A lower folded piece, which is the folded piece that is folded back so that its tip is positioned above the upper surface of the lower base piece or below the lower surface of the lower hinge receiving piece, A bent piece that protrudes from the outer peripheral edge of the lower hinge receiving piece and is bent downward at a location where the lower folded piece does not contact with the side hinge receiving piece. The gist of the present invention is that a bent portion is formed that protrudes from the outer peripheral edge of the lower base piece and is bent upward at a location where the lower folded piece and the bent piece are not in contact with each other. And
The gist of the invention described in claim 3 is that, in claim 2, the width of the tip portion of the lower folded piece is smaller than the width of the tip portion of the upper folded piece.
According to a fourth aspect of the present invention, in any one of the first to third aspects, the first hinge part has a restriction piece protruding in a direction opposite to the hinge receiving piece with respect to the vertical frame piece. The gist of the present invention is that the second butterfly part is provided with a restriction port for engaging the restriction piece.

The gist of a fifth aspect of the present invention is that, in any one of the first to fourth aspects, the folded piece is formed on the base piece .

Therefore, according to the fifth aspect of the present invention, it is possible to more reliably prevent the act of inserting the instrument into the gap between the base portion and the hinge receiving portion to deform the hinge receiving portion or the base portion.

The support portion is a support shaft that protrudes from the upper surface of the base portion and is inserted into the hole portion as the supported portion, and the upper surface of the tip portion of the folded portion formed in the base portion is It is preferable to arrange so as to be lower than the upper end of the support shaft.

In this case, even if an instrument is inserted between the base part and the hinge receiving part to deform the hinge receiving part or the base part with the support shaft inserted into the hole part, The provided hole part maintains the state located below the upper end of the support shaft. That is, since the state where the support shaft is inserted into the hole portion is maintained, an unauthorized device is inserted between the first frame and the second frame, and the hinge receiving portion or the base portion is deformed to depend on the support portion. Unauthorized acts performed by releasing the support of the supported portion can be prevented more reliably.

Moreover, it is preferable that the said hinge receiving part is each provided in the upper end and lower end of the said vertical frame part.

In this way, when the base portion is positioned on the lower surface side of each hinge receiving portion, the folded portion is also positioned on the upper end side and the lower end side of the vertical frame portion, respectively. For this reason, it is possible to prevent the instrument from being inserted into the gap between the base portion and the hinge receiving portion on both the upper end side and the lower end side. Therefore, it is possible to more reliably prevent a fraudulent act that is caused by generating a gap between the first frame and the second frame so that a fraudulent instrument can be inserted.

Further, the with the support portion is disposed at the distal end portion of the base portion, the folded portion formed in the base portion that is disposed in the vicinity of the support portion preferably.

  By the way, in the prior art described in Patent Document 1, the support shaft is arranged at the tip of the hinge member on the outer frame side. The engaging concave portion of the wearing member is arranged several cm or more away from the support shaft. Therefore, if an instrument is inserted between both hinge members and the hinge member is deformed, it will come off from the support shaft before the locking claw pieces and the engagement recesses function.

Therefore , if the folded portion is disposed in the vicinity of the support portion, even if an instrument is inserted between the base portion and the hinge receiving portion in the vicinity of the support portion to attempt to deform the hinge receiving portion or the base portion, the hinge receiving portion. Immediately the upper surface of the abuts against the tip of the folded portion. Therefore, since the deformation of the hinge receiving part or the base part is more reliably prevented, the support of the supported part by the support part can be reliably prevented from being released.

The tip portion of the folded portion is oriented perpendicular to the front of the gaming machine, the lower surface of the tip portion is preferably arranged substantially parallel to the upper surface of the base portion.

  By the way, in the prior art described in Patent Document 1, the distal end portion of the locking claw piece of the outer frame side hinge member protrudes forward of the gaming machine, and thus constitutes the outer frame side hinge member. It is easy to deform by inserting an instrument between the horizontal piece and the locking claw piece.

Therefore, the direction in which the distal end portion of the folded portion is orthogonal to the front of the gaming machine (i.e., the lateral direction of the gaming machine) if to face, a gap between the tip and the hinge receiving portion of the folded portion, exposed to the front It becomes difficult to insert the instrument between the folded portion and the base portion. For this reason, it becomes easy to prevent the fraudulent act which produces the clearance gap which can insert a fraudulent instrument between the 1st frame and the 2nd frame.
According to a sixth aspect of the present invention, in the second or third aspect, the support shaft is disposed at a tip portion of the lower base piece, and the lower folded piece formed on the lower base piece is the The gist is that the support shaft is disposed in the vicinity of the support shaft, and the support shaft is surrounded by the lower folded piece, the bent piece, and the bent portion.

As described above in detail, according to the first to sixth aspects of the present invention, there is provided a gaming machine that can reliably prevent a fraudulent act that is caused by creating a gap that allows a fraudulent instrument to be inserted between the frames. it is possible.

The protruding amount of the bent piece 79 is substantially equal to the thickness of the flange portion 74a. Due to the bent piece 79 and the bent piece 57 on the lower hinge receiving piece 53b side, a gap generated between the base piece 73 and the lower hinge receiving piece 53b is not exposed forward in a state where the front frame 2 is closed. .

  As shown in FIGS. 6 to 8, 10, and the like, the base piece 73 is integrally formed with a folded piece 77 as a “folded portion”. The folded piece 77 protrudes from substantially the entire left side of the outer peripheral edge of the base piece 73 and is folded to the upper surface 73 a side of the base piece 73. That is, the front end portion 78 of the folded piece 77 is folded so as to face a direction perpendicular to the protruding direction of the base piece 73 (a direction perpendicular to the front of the slot machine 1). More specifically, the base end portion 80 of the folded piece 77 is bent perpendicularly to the base piece 73, and the distal end portion 78 of the folded piece 77 is bent perpendicularly to the base end portion 80 to form the base piece. 73 is located above the upper surface 73a of 73. The width of the connecting portion between the distal end portion 78 and the proximal end portion 80 is considerably smaller than the width of the proximal end portion 80, and is set to about 1/3 of the proximal end portion 80 in the present embodiment. In addition, the width of the connection portion between the distal end portion 78 and the base end portion 80 is smaller than the width of the distal end portion 68 of the folded piece 67 of the upper second hinge portion 61. The width of the tip 78 gradually decreases as it goes to the tip. The folded piece 77 is arranged in the vicinity of the support shaft 74, and the shortest distance from the support shaft 74 is set to 1 cm or less (about 0.8 cm in the present embodiment). The front end portion 78 is disposed close to the upper surface 53d of the lower hinge receiving piece 53b in a state where the front frame 2 is closed (see FIGS. 6A and 10B). The upper surface 78a of the front end portion 78 is disposed so as to be lower than the upper end of the support shaft 74, and the lower surface 78b of the front end portion 78 is disposed so as to be higher than the flange portion 74a (FIG. )reference). Further, the lower surface 78b of the distal end portion 78 is disposed substantially parallel to the upper surface 73a of the base piece 73, but the distance between the distal end portion 78 and the upper surface 73a slightly increases toward the distal end. For this reason, when closing the front frame 2, it becomes easy to guide the lower hinge receiving piece 53b between the base piece 73 and the tip 78.

  Next, operations of the first butterfly portion 51, the upper second hinge portion 61, and the lower second hinge portion 71 will be described.

  In the present embodiment, a folded piece 77 is provided on the base piece 73, and a folded piece 67 is provided on the base piece 63. For this reason, even if an instrument is inserted into the gap between the base piece 73 and the lower hinge receiving piece 53b to deform the lower hinge receiving piece 53b, the upper surface 53d of the lower hinge receiving piece 53b remains at the tip of the folded piece 77. Since the contact with the portion 78 is prevented, the support shaft 74 cannot be removed from the hole 54b. Similarly, even if an instrument is inserted into the gap between the base piece 63 and the upper hinge receiving piece 53a to deform the upper hinge receiving piece 53a, the upper surface 53c of the upper hinge receiving piece 53a is connected to the tip end portion 68 of the folded piece 67. Since the contact is prevented, the support shaft 64 cannot be removed from the hole 54a. Therefore, since a gap cannot be formed between the front frame 2 and the middle frame 3, it is possible to reliably prevent an unauthorized device from entering through the gap.

  Further, the upper surface 78 a of the tip 78 of the folded piece 77 is disposed so as to be lower than the upper end of the support shaft 74, and the folded piece 77 is disposed in the vicinity of the support shaft 74. Further, the upper surface 68 a of the tip end portion 68 of the folded piece 67 is disposed so as to be lower than the upper end of the support shaft 64, and the folded piece 67 is disposed in the vicinity of the support shaft 64. Therefore, even if an instrument is inserted between the base piece 73 and the lower hinge receiving piece 53b to deform the lower hinge receiving piece 53b, the hole 54b provided in the lower hinge receiving piece 53b The state where the support shaft 74 is inserted is maintained. In addition, since the folded piece 77 is in the vicinity of the support shaft 74, even when an instrument is inserted to deform the lower hinge receiving piece 53 b, the upper surface 53 d of the lower hinge receiving piece 53 b immediately contacts the folded piece 77. It is more reliably prevented by touching. Similarly, even if an instrument is inserted between the base piece 63 and the upper hinge receiving piece 53a to deform the upper hinge receiving piece 53a, the hole portion 54a provided in the upper hinge receiving piece 53a has a support shaft. The state where 64 is inserted is maintained. In addition, since the folded piece 67 is in the vicinity of the support shaft 64, the upper surface 53c of the upper hinge receiving piece 53a immediately contacts the folded piece 67 even if an instrument is inserted to deform the upper hinge receiving piece 53a. It is prevented more reliably. Therefore, it is possible to more surely perform an illegal act by inserting a fraudulent instrument between the front frame 2 and the middle frame 3 and removing the support shaft 74 from the hole 54b or removing the support shaft 64 from the hole 54a. Can be prevented.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) According to the slot machine 1 of the present embodiment, an instrument is inserted into the gap between the base piece 63 and the upper hinge receiving piece 53a to deform the upper hinge receiving piece 53a and remove the support shaft 64 from the hole 54a. The action is prevented by the folded piece 67. Further, the folding piece 77 prevents the act of inserting an instrument into the gap between the base piece 73 and the lower hinge receiving piece 53b to deform the lower hinge receiving piece 53b and remove the support shaft 74 from the hole 54b. . Therefore, it is possible to reliably prevent an illegal act performed by inserting an unauthorized instrument into the slot machine 1 through a gap generated between the front frame 2 and the middle frame 3.

  (2) Since the upper second hinge part 61 of the present embodiment is integrally formed with the folded piece 67, the upper second hinge part 61 has a three-dimensional shape and is difficult to be deformed. The rigidity of 63 is improved. Thereby, it becomes easy to support the front frame 2 by the upper second butterfly 61. By the way, since the weight of the front frame 2 is applied to the lower second hinge part 71 of the present embodiment, higher rigidity than that of the upper second hinge part 61 is required. However, since the lower second hinge part 71 is integrally formed with the folded piece 79 in addition to the folded piece 77, the lower second hinge part 71 has a three-dimensional shape and is not easily deformed. The rigidity of the base piece 73 is higher than that of the base piece 63. Therefore, the front frame 2 can be easily supported by the lower second butterfly portion 71.

  (3) For example, when the folded pieces 67 and 77 are formed on the mounting pieces 62 and 72 located far from the hinge receiving pieces 53a and 53b, it is necessary to increase the number of times of folding when the folded pieces 67 and 77 are formed. Therefore, formation of the folding pieces 67 and 77 is difficult. On the other hand, the folding pieces 67 and 77 of the present embodiment are formed on the base pieces 63 and 73 located closer to the hinge receiving pieces 53a and 53b than to the mounting pieces 62 and 72. As a result, since the number of times of folding when the folded pieces 67 and 77 are formed is reduced, the folded pieces 67 and 77 can be easily formed.

  (4) In the present embodiment, the metal plate that forms the first butterfly portion 51 is thinner than the metal plate that forms the upper second hinge portion 61 and the lower second hinge portion 71. Thereby, since the front frame 2 to which the first hinge part 51 is attached is reduced in weight, the front frame 2 can be easily rotated.

  (5) In the present embodiment, the restriction piece 55 is provided in the first hinge part 51 and the restriction port 65 for engaging the restriction piece 55 is provided in the upper second hinge part 61. Thereby, the act of causing the front frame 2 to move upward with the support shaft 64 (or support shaft 74) inserted into the hole 54a (or hole 54b) to create a gap with the middle frame 3, This is prevented not only by the folded pieces 67 and 77 coming into contact with the hinge receiving pieces 53a and 53b but also by the restriction piece 55 engaging the restriction opening 65. Therefore, it is possible to more reliably prevent an illegal act performed by inserting an illegal instrument into the slot machine 1.

  In addition, you may change embodiment of this invention as follows.

  In the above embodiment, the base piece 63 is formed with the folded piece 67 protruding from the base piece 63 and the tip 68 is folded, and the base piece 73 is projected from the base piece 73 and the tip 78 is formed.
