Description

The present invention relates to a gaming machine board case that houses a control board in a housing space formed by combining a case body and a lid member.

  Conventionally, gaming machines such as pachinko machines and slot machines have been provided with a control board having various electronic circuits and programs for controlling the gaming operations.

  By the way, in recent years, such a control board is replaced with an illegal control board containing a program advantageous to itself, or an illegal signal is given to the control board to cause a malfunction, etc. There are cases where fraudulent acts such as winning a lot of prize balls are performed on pachinko machines, which is a problem.

  Therefore, in order to prevent fraudulent acts on the control board, some important control boards are attached to the gaming machine in a state of being accommodated in a board case having a special structure as described in Patent Document 1, for example. It is like that. Such a substrate case is generally formed by fixing a body cylinder part integrally formed with a case body and a lid cylinder part integrally formed with a lid member to each other with a stopper such as a screw, for example. The main body and the lid member are fixed in a sealed state. And by providing a plurality of sets of the main body cylinder part and the cover cylinder part, a plurality of times of sealing and unsealing can be performed.

  In this case, in order to open the substrate case, the main body cylinder part and the lid cylinder part fixed to each other must be broken away from the case, and a trace of destruction remains. Therefore, the number of times of opening the substrate case can be known from the number of traces of such destruction, and when it is different from the planned number of times of opening, it is possible to detect that the opening has been made illegally and to prevent unauthorized opening. Can be prevented.

  However, since the board case of the gaming machine is formed to be transparent so that the internal state can be seen from the outside, the main body cylinder part and the cover cylinder part formed integrally with the board case are also transparent. There are often. Therefore, there is a problem that the number of the main body cylinder part and the cover cylinder part separated from the substrate case is difficult to distinguish at a glance.

  In addition, in the substrate case described in Patent Document 1, it is possible to open the substrate case without leaving a trace by opening the stopper by using a special tool or the like. Therefore, for example, as described in Patent Document 2 and Patent Document 3, a board case for a gaming machine that makes it difficult to open the stopper by bonding and fixing the stopper is also proposed.

  However, even in gaming machine board cases as described in Patent Document 2 and Patent Document 3, for example, a board case that reproduces a state in which a stopper is adhered is prepared, and the entire board case is replaced with an unauthorized control board. In such cases, it was difficult to detect fraud.

Japanese Patent Laid-Open No. 10-249021 JP 2004-49428 A JP 2002-253811 A

  Here, the present invention has been made in the background as described above, and the problem to be solved is that it is possible to more easily confirm the number of times of opening, and forgery for each substrate case. It is an object of the present invention to provide a gaming machine board case having a novel structure that can be effectively dealt with.

  Hereinafter, embodiments of the present invention made to solve the above-described problems will be described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible.

  That is, according to the first aspect of the present invention, in the state in which the plurality of main body cylindrical portions integrally formed with the case main body and the inner spaces of the plurality of lid cylindrical portions integrally formed with the lid member are connected, And at least one set of the lid tube portion is fixed to each other with a stopper to form a housing space surrounded by the case body and the lid member, and for a gaming machine that houses the control board in the housing space In the substrate case, the case main body is transparent including the main body cylindrical portion, and the lid member is transparent including the lid cylindrical portion, and the adhesive accommodating portion for accommodating the adhesive is the main body cylinder. An outlet means for allowing the adhesive to flow out from the adhesive accommodating portion by an insertion operation of the stopper, and the adhesive discharged by the outlet means While the stopper is fixed in the inserted state, the outflow hand In the color of the outflow allowed was adhesive, that as allowed to change differently from the color of the adhesive before outflow by the insertion operation of 該止 Me tool, characterized.

  According to the gaming machine substrate case structured according to this aspect, since the stopper is fixed to at least one of the main body cylinder part or the cover cylinder part with an adhesive, the main body cylinder part and the cover cylinder part are fixed. Is expressed more firmly. Thereby, it can be made more difficult to cancel the assembled state of the case body and the lid member.

  In addition, since the adhesive is applied to the main body cylinder part, the cover cylinder part, and the stopper, if you try to open the case by improperly operating the stopper, there will be no evidence of scratches on the adhesive. Remains. Therefore, for example, like a structure in which the stopper is concealed by the cap member, it is possible to reduce the possibility that the appearance similar to that before opening is reproduced by being sealed with a new cap member after unauthorized opening.

  At the same time, particularly in this embodiment, when the adhesive accommodated in the adhesive accommodating portion is caused to flow out by the outflow means, it is changed to a color different from that before the outflow. The color before hardening before flowing out is different from the color after hardening discharged from the adhesive container. Therefore, in order to forge the color of the adhesive, it is necessary to grasp the composition of the adhesive and the blending amount of the mixed colorant, and it is very difficult to forge the same color adhesive. is there. Therefore, forgery in which the stopper is again bonded with an adhesive prepared separately after the bonded stopper is forcibly pulled out can be detected more easily because the color of the adhesive is different. In addition, since it is difficult to counterfeit the adhesive, it is also difficult to counterfeit the board case that reproduces the state where the fasteners are adhered, and more effectively counters counterfeiting for each board case. I can do it. Note that the color of the adhesive in this embodiment includes not only colored but also colorless.

  In addition, the adhesive used to seal the substrate case is discolored from the state of accommodation in the adhesive container, and the color is different from the adhesive that has not yet been used. The number of times of opening the substrate case can be easily confirmed from the number of the main body cylinder portion and the lid cylinder portion where the agent is present or the number of the main body cylinder portion and the lid cylinder portion where the adhesive that has not yet been discolored exists.

  And according to this aspect, since the fixing of the stopper with the adhesive and the discoloration of the adhesive are performed along with the insertion operation of the stopper, the case assembly process is not increased without increasing the number of cases. The effect of preventing the action and the ease of checking the number of times of opening are improved.

  In addition, various things can be employ | adopted as a fastener in this aspect, A bidirectional | two-way screw, a one-way screw, or a spring pin etc. are illustrated. Also, various modes can be adopted as the specific structure of the adhesive accommodating portion for accommodating the adhesive and the outflow means for allowing the adhesive to flow out from the adhesive accommodating portion, for example, on the inner peripheral surface of the main body cylindrical portion. An opening space is formed in the main body cylinder portion, and the opening portion is covered with a lid in a state where the adhesive agent is accommodated in the space. The adhesive may flow out by abutting against the lid and opening the lid, or a bag body enclosing the adhesive may be provided as an adhesive container in the main body cylinder so that the stopper can be inserted. The bag body may be broken with a stopper to allow the adhesive to flow out.

  In addition, as a specific method for discoloring the adhesive that has flowed out of the adhesive container, as a second aspect of the present invention, in the gaming machine substrate case according to the first aspect, the adhesive may be used. As a two-pack type adhesive composed of a main agent and a curing agent, the main agent and the curing agent are colored in different colors and separately stored in a plurality of adhesive accommodating portions, and the outflow means removes the adhesive from the adhesive accommodating portion. A mode in which they flow out and mix with each other can be suitably employed.

  If it does in this way, the adhesive agent flowed out from the adhesive agent accommodating part can be easily changed into a different color. Since the main agent and the curing agent are colored, in order to counterfeit the adhesive, it is necessary to counterfeit the colors of the main agent and the curing agent. Thereby, forgery of an adhesive agent can be made more difficult. In this embodiment as well, it is possible to adopt colorless as the colors of the main agent and the curing agent. For example, when the main agent is colored and the curing agent is colorless, by mixing these two agents, the color of the main agent is diluted with the curing agent and different colors are developed.

  Furthermore, as a specific method for discoloring the adhesive that has flowed out of the adhesive container, as a third aspect of the present invention, in the gaming machine substrate case according to the first or second aspect, A mode in which a microcapsule containing a colorant is mixed in an adhesive, and the microcapsule is broken by the operation of inserting the stopper to cause the colorant to flow out can be suitably employed.

  In this way, the color of the one-component adhesive can be changed before and after the outflow from the adhesive container. Further, for example, from a substantially colorless and transparent state, it is possible to disperse the colorant and change it to a predetermined color. Therefore, this embodiment can also be used for a two-component adhesive. For example, the main agent and the curing agent are accommodated in the adhesive accommodating portion in a substantially colorless and transparent state using this embodiment. In addition, a predetermined color may be developed by breaking the microcapsules during outflow and mixing from the adhesive container.

  Furthermore, this aspect can be used in combination with the second aspect. For example, microcapsules containing a colorant having a color different from the colors of the main agent and the curing agent are mixed into the pre-colored main agent and the curing agent. In this way, when the main agent and the curing agent are mixed with each other, the colorant contained in the microcapsule can also be mixed, and the color is simply different from the color in which the main agent and the curing agent are mixed. It can also be changed.

  Hereinafter, in order to clarify the present invention more specifically, embodiments of the present invention will be described in detail with reference to the drawings.

  First, FIG. 1 and FIG. 2 show a board case 10 according to a gaming machine board case as a first embodiment of the present invention. The substrate case 10 is a case that accommodates a control substrate 12 that controls the operation of a gaming machine such as a pachinko machine or a slot machine, and has a structure in which a lid member 16 is superimposed on the case body 14 and assembled. In a state where the control board 12 is accommodated, the control board 12 is attached to an appropriate position of the gaming machine. In the following description, the vertical direction means the vertical direction in FIG. 2 unless otherwise specified.

  More specifically, the case main body 14 is formed of a transparent hard synthetic resin material such as polycarbonate (PC), and as shown in FIG. 3, along the outer peripheral edge portion of the rectangular bottom plate 18. A peripheral wall 20 extending over the entire circumference is integrally provided so as to have a substantially box shape opening to one side.

  Further, a plurality of (four in the present embodiment) main body cylinder portions 24 are provided on one side wall 22 of the case body 14 in the longitudinal direction (left side in FIG. 3), and the side wall 22 extends (in FIG. 3). , In the up-down direction). The main body cylinder portion 24 has a bottomed cylindrical shape having a pin insertion hole 25 that opens upward, and is integrally formed with a columnar main body connection portion 26 that extends outward (leftward in FIG. 3) from the side wall 22. Has been. Thereby, the case main body 14 is integrally formed including the main body cylinder portion 24 and the main body connecting portion 26.

  Here, the axial direction of the main body cylinder portion 24 is equal to the overlapping direction of the case main body 14 and the lid member 16 (vertical direction in FIG. 2), and the opening direction of the pin insertion hole 25 (main body cylinder portion 24). The direction in which the central axis of the case 14 extends and the opening direction of the case body 14 (a direction substantially orthogonal to the bottom plate 18) are substantially parallel to each other. Further, the upper surfaces of the main body cylinder portion 24, the main body connection portion 26, and the side wall 22 are formed on the same plane, while the lower end surface of the main body cylinder portion 24 is positioned slightly above the bottom plate 18 ( (See FIG. 5).

  The case body 14 having such a structure is provided with mounting pieces at appropriate positions such as the bottom plate 18 and the peripheral wall 20, and the case body 14 is configured to include the case main body via the mounting pieces. The board case 10 can be attached to a predetermined position of the gaming machine.

  On the other hand, the lid member 16 is formed of a transparent hard synthetic resin material such as polycarbonate (PC), like the case main body 14, and as shown in FIG. A peripheral wall 30 (see FIG. 5) extending along the entire periphery of the peripheral portion is integrally projected so as to have a substantially box shape opened to one side.

  Furthermore, the side wall 32 on one side in the longitudinal direction of the lid member 16 (left side in FIG. 4), more specifically, on the side where the main body cylinder portion 24 is positioned in the assembled state to the case main body 14, An equal number (four in this embodiment) of lid cylinders 34 are integrally formed side by side in the extending direction of the side wall 32 (the vertical direction in FIG. 4). The lid cylinder part 34 has a substantially cylindrical shape having through holes 36 opened in both axial directions, and is integrally formed with a columnar lid coupling part 38 extending outward (leftward in FIG. 4) from the side wall 32. Has been. Thereby, the lid member 16 is integrally formed including the lid cylinder part 34 and the lid coupling part 38.

  Each of the plurality of lid cylinders 34 has an equal shape, and has a substantially cylindrical shape opening upward with an outer diameter dimension equal to the outer diameter dimension of the main body cylinder part 24 provided in the case body 14. The extending direction of the central axis is equal to the overlapping direction of the case main body 14 and the lid member 16. Further, the bottom surfaces of the lid cylinder part 34, the lid coupling part 38, and the side wall 32 are formed on the same plane, while the upper end surface of the lid cylinder part 34 is positioned slightly below the top plate 28. (See FIG. 5).

  As shown in FIG. 5, in the present embodiment, the through hole 36 is formed with a step surface 40 that protrudes radially inward at the lower end in the axial direction, and the axially lower side is sandwiched by the step surface 40. A small-diameter pin insertion hole 42 is provided, and an axially upper portion is a large-diameter head insertion hole 44. Here, the diameter dimension of the pin insertion hole 42 is equal to the diameter dimension of the pin insertion hole 25 formed in the main body cylinder portion 24, and is smaller than the diameter dimension of the pressing plate portion 70 of the pin 62 described later. On the other hand, the diameter of the head insertion hole 44 is slightly larger than the diameter of the pressing plate 70.

  Further, in particular, the cover cylinder portion 34 in the present embodiment is formed with a pair of accommodation cavities 46 a and 46 b so as to surround the head insertion hole 44. The accommodation cavities 46a and 46b are cavities extending with a predetermined width in the circumferential direction of the lid cylinder portion 34. In the present embodiment, the accommodation vacancies 46a and 46b each have a substantially half circumference around the lid cylinder portion 34. It is formed with a circumferential length. Further, in the accommodation cavities 46a and 46b, an air hole 48 is formed at an appropriate position at the upper end in the axial direction of the lid cylinder portion 34, and an exhaust hole 50 is formed at an appropriate position at the lower end. The air holes 48 and the discharge holes 50 are opened on the inner peripheral surface 51 of the head insertion hole 44 so that the accommodation cavities 46a and 46b communicate with the external space. And the opening part to the head insertion hole 44 of the air hole 48 and the discharge hole 50 is liquid-tightly sealed by the sealing pin 52 integrally formed with the cover cylinder part 34. FIG.

  Adhesives are accommodated in these accommodation spaces 46a and 46b. As such an adhesive, various conventionally known adhesives can be appropriately employed. However, in the present embodiment, a two-pack type epoxy adhesive is used, and the main agent is provided in one accommodation space 46a. (A agent) 54a is accommodated, and a curing agent (B agent) 54b is accommodated in the other accommodation space 46b. In addition, in order to facilitate mixing of the A agent and the B agent by the operation of inserting the pin 62, which will be described later, or to facilitate the flow in the communication passage 78, the ultra low viscosity A agent and the ultra low viscosity B agent are used. It is more preferable. Thus, in this embodiment, the adhesive accommodating part is comprised including the accommodation empty spaces 46a and 46b.

  Further, the colors of the main agent 54a and the curing agent 54b are made different from each other by, for example, mixing a pigment. In the present embodiment, the main agent 54a is colored red and the curing agent 54b is colored blue. In particular, in this embodiment, since the lid member 16 and the lid cylinder portion 34 formed integrally with the lid member 16 are transparent, the colors of the main agent 54a and the curing agent 54b accommodated in the accommodation cavities 46a and 46b. Is visible from the outside.

  The lid cylinder portion 34 having such a structure is integrally connected to the lid member 16 via a lid coupling portion 38 that is orthogonal to the side wall 32 and protrudes outward in the horizontal direction of the lid member 16. Yes. In addition, the protrusion dimension and the width dimension from the side wall 32 of the lid connection part 38 are made equal to the protrusion dimension and the width dimension from the side wall 22 of the main body connection part 26. Further, the separation distance in the arrangement direction of the lid connection portions 38 is equal to the separation distance in the arrangement direction of the main body connection portions 26.

  Although not shown, the lid member 16 has a window for connecting the connector provided on the control board 12 to the outside, a heat exhaust hole for discharging the heat of the control board 12 to the outside, and the like. Formed. The control board 12 is fixed to the lid member 16 by screws or the like. The control board 12 is a control board that controls the operation of the gaming machine, and is based on a main control board that controls the overall operation of the pachinko machine or slot machine as a gaming machine or a control signal from the main control board. An example is a payout control board for controlling payout of award media.

  When assembling the case main body 14 and the lid member 16 having the above-described structure, first, the case main body 14 and the lid member 16 to which the control board 12 is attached are opposed to each other, and the lid member 16 are overlapped in a state slightly shifted in the direction opposite to the side where the main body cylinder portion 24 of the case main body 14 is provided (the right direction in FIG. 1).

  Then, the lid member 16 is slid and displaced with respect to the case main body 14 in the direction in which the main body cylinder portion 24 is provided. In particular, in the present embodiment, a pair of protrusions 56, 56 projecting outward are formed at the end of the case main body 14 opposite to the side where the main body cylinder portion 24 is formed. A projecting plate portion 58 projecting downward is formed on the side of the peripheral wall 30 opposite to the side on which the lid tube portion 34 is formed. The projecting plate portion 58 corresponds to the projection 56 in the assembled state to the case body 14. A pair of insertion holes 60, 60 that are opened inward are formed at the positions to be opened. Then, when the lid member 16 is slidably displaced with respect to the case main body 14, the projection 56 is fitted into the insertion hole 60. Thereby, the site | part on the opposite side to the side in which the main body cylinder part 24 and the cover cylinder part 34 of the case main body 14 and the cover member 16 were provided will be mutually fixed. In addition, as a specific structure for assembling the case main body 14 and the lid member 16, various assembling structures in the board case for gaming machines can be appropriately employed and are limited to the above-described structures. Not.

  Then, as described above, the lid member 16 is slid and displaced with respect to the case main body 14, so that the respective lid cylinder portions 34 provided on the lid member 16 are displaced on the main body cylinder portion 24 of the case main body 14. . Thereby, as shown also in FIG. 5, each main body cylinder part 24 and the cover cylinder part 34 are piled up on the same central axis in the up-down direction. Thereby, the pin insertion hole 25 of the main body cylinder part 24 and the through hole 36 of the cover cylinder part 34 are overlapped on the same central axis and communicated with each other. The internal spaces are communicated with each other. In addition, the main body cylinder part 24 and the lid cylinder part 34 do not necessarily need to be in contact with each other, and may be positioned with a gap therebetween.

  Next, a pin 62 as a stopper is inserted and fixed to any one of the pair of the main body cylinder portion 24 and the lid cylinder portion 34 positioned on the same central axis. A pin 62 is shown in FIGS. The pin 62 is configured by assembling a pressing member 66 to the spring pin 64.

  The spring pin 64 is formed by rounding a plate material such as steel, spring steel, spring stainless steel or the like, and has a cylindrical shape in which a notch 68 extending while meandering in the axial direction is formed in a part of the circumferential direction. Yes. As a result, the spring pin 64 is configured to generate a restoring force in the diameter increasing direction by applying a force in the diameter decreasing direction. The spring pin 64 is slightly larger in diameter than the pin insertion holes 25 and 42 of the main body cylinder portion 24 and the lid cylinder portion 34 in a state where a force in the diameter reducing direction is not exerted. The specific shape of the spring pin 64 is merely an example. For example, a linear shape extending in the axial direction may be adopted as the cut 68. It is also possible to form the spring pin 64 by winding a plate material one or more times.

  On the other hand, the pressing member 66 is integrally formed with an insertion shaft 72 that protrudes to one side in the thickness direction from the central portion of the pressing plate portion 70 that has a diameter larger than the diameter of the spring pin 64 and has a disk shape as a whole. It is a formed structure. Here, the diameter dimension of the pressing plate portion 70 is larger than the diameter dimension of the pin insertion hole 42 in the lid cylinder portion 34 and slightly smaller than the diameter dimension of the head insertion hole 44. Further, the pressing plate portion 70 is formed with one notch 74 as a through passage that opens outward in the radial direction and penetrates in the thickness direction. Note that the dimension of the notch 74 in the radial direction of the pressing plate portion 70 is such that when the pin 62 described later is pushed in, the sealing pin 52 that protrudes into the head insertion hole 44 of the lid cylinder portion 34 is provided in the notch 74. In order to prevent passing through, it is preferable that the size of the sealing pin 52 be smaller than the protruding dimension into the head insertion hole 44. Then, the insertion shaft 72 is inserted from one end of the spring pin 64 in the axial direction, whereby the pin 62 is configured, and the pressing plate portion 70 is provided in a hook shape protruding radially outward at the pin 62. At the same time, the notch 74 formed in the pressing plate portion 70 is displaced in the radial direction with respect to the spring pin 64 and is positioned away from the central axis of the spring pin 64. As described above, in the present embodiment, the leg portion of the stopper is configured by the spring pin 64, and the head portion of the stopper is configured by the pressing plate portion 70. The end of the spring pin 64 opposite to the side on which the pressing plate portion 70 is provided is the insertion end 75.

  As shown in FIG. 5, the pin 62 having such a structure is inserted from the upper opening portion of the through hole 36 in the cover cylinder portion 34 toward the main body cylinder portion 24 from the insertion end portion 75. . Then, by pressing the upper surface 76 of the pressing plate portion 70 with a tool or the like, the spring pin 64 straddles the pin insertion hole 42 of the cover cylinder portion 34 and the pin insertion hole 25 of the main body cylinder portion 24 as shown in FIG. insert. Thus, in the present embodiment, the upper surface 76 of the pressing plate portion 70 is an insertion operation end surface on which a tool or the like acts during the insertion operation. As a result, the spring pin 64 is inserted across the pin insertion holes 42 and 25 of the lid cylinder portion 34 and the main body cylinder portion 24 to reduce the diameter. As a result, the restoring force of the spring pin 64 acts on the pin insertion holes 42 and 25, and the outer peripheral surface of the spring pin 64 is pressed against the inner peripheral surfaces of the pin insertion holes 42 and 25. In this way, the pair of main body cylinder part 24 and lid cylinder part 34 are fixed to each other via the spring pin 64.

  Further, particularly in the present embodiment, the pressing plate portion 70 of the pin 62 is protruded inward of the head insertion hole 44 in the process of inserting and pushing the pin 62 into the cover cylinder portion 34 and the main body cylinder portion 24. The sealing pin 52 is brought into contact with the sealing pin 52, and the sealing pin 52 is broken from the base end portion. As a result, the air holes 48 and the discharge holes 50 of the accommodation cavities 46a and 46b are opened in the head insertion hole 44, and the main agent 54a and the curing agent 54b respectively accommodated in the accommodation cavities 46a and 46b are stored in the head. It flows out into the part insertion hole 44. Thus, in this embodiment, the outflow means is configured including the sealing pin 52 and the pressing plate portion 70. It is more preferable that the sealing pin 52 has a hollow structure so that the accommodation cavities 46a and 46b can communicate with the external space regardless of where the sealing pin 52 is broken.

  In this case, the pin 62 is positioned in a state in which the pressing plate 70 is slightly lifted from the stepped surface 40 of the through hole 36 in the lid cylinder portion 34 in a state of being inserted into the lid cylinder portion 34 and the main body cylinder portion 24. At the same time, the opening of the pin insertion hole 42 opened in the stepped surface 40 of the lid cylinder portion 34 is sealed by the spring pin 64 of the pin 62 and the insertion shaft 72 of the pressing member 66 inserted in the spring pin 64. It has been stopped. As a result, the main agent 54a and the curing agent 54b that have flowed out of the accommodation cavities 46a and 46b are mixed and deposited on the step surface 40 while hardly falling into the pin insertion hole 42.

  Further, a communication passage 78 is formed between the notch 74 in the pressing plate portion 70 of the pin 62 and the inner peripheral surface 51 of the head insertion hole 44 to communicate the upper surface 76 and the lower surface 79 of the pressing plate portion 70 in the insertion direction. Is done. As a result, when the main agent 54a and the curing agent 54b are further deposited while being mixed with each other, the main agent 54a and the curing agent 54b pass through the communication path 78 from the lower surface 79 of the pressing plate portion 70 onto the upper surface 76. Thus, it is deposited on the upper surface 76. Thus, in the present embodiment, the communication path 78 is a flow path that causes the adhesive to wrap around the insertion operation end face of the stopper. Thereafter, the main agent 54 a is cured, and an adhesive layer 80 that covers substantially the entire pressing plate portion 70 including the upper surface 76 is formed. Thus, in this embodiment, the upper surface 76 of the pressing plate portion 70 as the insertion operation end surface is a covering surface covered with the adhesive. Then, the pressing member 66 of the pin 62 is bonded to the lid cylinder portion 34 with the adhesive layer 80, whereby the pin 62 is fixed in a state where the spring pin 64 is inserted into the pin insertion holes 25 and 42. Become.

  Further, particularly in the present embodiment, the main agent 54a is colored red and the curing agent 54b is colored differently from blue. As a result, the main agent 54a and the curing agent 54b that have flowed out of the accommodation cavities 46a and 46b are mixed, whereby a purple color is developed in the adhesive layer 80. As described above, in this embodiment, the main agent 54a and the curing agent 54b as adhesives are uncured color accommodated in the accommodation cavities 46a and 46b after the curing is caused to flow out from the accommodation cavities 46a and 46b. It can be changed to a different color. In the present embodiment, when the pin 62 is pushed in, the pressing plate portion 70 and a tool for pushing the pin 62 enter the main agent 54a and the curing agent 54b, thereby mixing the colors of the main agent 54a and the curing agent 54b. This is more suitably performed.

  As described above, the main body cylinder portion 24 and the lid cylinder portion 34 are fixed to each other by the restoring force of the spring pin 64, and the pin 62 is fixed by the adhesive layer 80. The portion 34 is fixed so as not to be released. As a result, the lid member 16 is fixed to the case body 14, and an accommodation space 82 is formed between the case body 14 and the lid member 16, and the control board 12 is accommodated in the accommodation space 82.

  When the lid member 16 is removed from the case main body 14, the main body cylinder portions fixed to each other by cutting the connecting portion formed by overlapping the main body connecting portion 26 and the lid connecting portion 38 with a tool such as a nipper. 24 and the lid cylinder part 34 are separated from the case main body 14 and the lid member 16. Thereby, the fixed state of the case main body 14 and the lid member 16 is released, and the lid member 16 can be displaced in the assembly release direction (rightward in FIG. 1) with respect to the case main body 14. .

  In the substrate case 10 having the structure according to this aspect, since the pins 62 are fixed by the adhesive layer 80, it is possible to make it more difficult to forcibly pull out the pins 62. Thereby, the fixed state of the main body cylinder part 24 and the cover cylinder part 34 can be expressed more firmly, and unauthorized opening can be prevented more effectively.

  In particular, in this embodiment, substantially the entire pressing member 66 of the pin 62 is covered with the adhesive layer 80, and the upper surface 76 of the pressing plate portion 70 is covered with the adhesive layer 80. Thereby, the contact of the tool with the press plate part 70 from the outside can be made substantially impossible. Therefore, it is possible to more effectively reduce the possibility that the pin 62 is illegally opened by hooking the pressing plate portion 70 with a tool or the like and forcibly pulling it out. Further, particularly in the present embodiment, the pressing plate portion 70 and the inner peripheral surface 51 of the head insertion hole 44 are formed by making the diameters of the head insertion holes 44 of the pressing plate portion 70 and the lid cylinder portion 34 substantially equal. So that almost no gap is formed between the pressing plate portion 70 and the inner peripheral surface 51 of the head insertion hole 44, and it is difficult to insert a tool into the gap. In addition, since there is only one notch 74 formed in the pressing plate portion 70, it is difficult to pull the pin 62 by hooking a tool on the notch 74. Further, particularly in the present embodiment, the discharge holes 50 of the accommodation cavities 46a and 46b are positioned above the pressing plate portion 70 of the pin 62 in the inserted state. As a result, the main agent 54a and the curing agent 54b are allowed to flow out onto the upper surface 76 of the pressing plate portion 70 so that the upper surface 76 can be more reliably covered.

  As described above, since the pin 62 is fixed by the adhesive layer 80, the fixing state of the main body cylinder part 24 and the cover cylinder part 34 can be expressed more firmly, and the unauthorized opening operation can be made more difficult. I can do it. For example, if the pin 62 is illegally pulled out, a trace such as a scratch remains on the adhesive layer 80. Thereby, it is possible to easily confirm the fact that the tampering has been opened. In addition, since the adhesive layer 80 remains scratched, it is possible to make a person who tries to open it illegally and to prevent illegal acts.

  Further, particularly in the present embodiment, the main agent 54a and the curing agent 54b are colored, and by mixing both colors, a color different from that before curing is expressed in the adhesive layer 80. Therefore, in order to reproduce the hue of the adhesive, it is necessary to examine the composition, and it is virtually impossible to reproduce the hue of the adhesive. Therefore, for example, even if the pin 62 is forcibly pulled out, the pin 62 is inserted again, and even if the upper surface 76 of the pressing plate portion 70 is covered with a new adhesive, the fact that it has been illegally opened due to the difference in color is revealed. And can make counterfeiting difficult. Further, since it is difficult to reproduce the color of the adhesive layer 80, it is also difficult to forge a substrate case in which the pins 62 are fixed with an adhesive. Can be dealt with more effectively. Further, in the present embodiment, since the adhesive layer 80 goes around the upper surface 76 of the pressing plate portion 70, the color of the adhesive layer 80 can be easily confirmed from above the substrate case 10.

  Furthermore, the adhesive layer 80 existing on the main body cylinder 24 and the lid cylinder 34 fixed to each other is colored so that the positions of the main body cylinder 24 and the lid member 34 fixed to each other can be easily visually confirmed from the outside. I can do it. Thereby, the opening frequency of the substrate case 10 can be easily confirmed. In particular, in the present embodiment, since the cover cylinder portion 34 is transparent, the colors of the main agent 54a and the curing agent 54b accommodated in the accommodation cavities 46a and 46b can be visually recognized from the outside. Therefore, the number of unused main body cylinder parts 24 and lid cylinder parts 34 can be easily confirmed.

  In the present embodiment, the outflow of the main agent 54a and the curing agent 54b from the accommodation cavities 46a and 46b, the color mixture of the main agent 54a and the curing agent 54b, and the covering of the pressing plate portion 70 are the operations for inserting the pin 62. To be done by. Thereby, without increasing the assembly process of the case main body 14 and the lid member 16, it is possible to improve the prevention effect against fraud and the ease of confirmation of the number of times of opening.

  Next, FIG. 9 shows the main part of a substrate case as a second embodiment of the present invention. In the following description, members and parts that are substantially the same as those of the first embodiment described above are denoted by the same reference numerals as those of the first embodiment, and detailed description thereof is omitted. To do.

  In the present embodiment, a pair of bag bodies 90a and 90b formed of, for example, an aluminum sheet or a laminate sheet with a resin is disposed on the step surface 40 of the lid cylinder portion 34, and the main agent is attached to the bag body 90a. While 54a is accommodated, the curing agent 54b is accommodated in the bag 90b. Thus, in this embodiment, the adhesive agent accommodating part is comprised by the bag bodies 90a and 90b.

  Then, as shown in FIG. 9A, the pin 62 is inserted into the through hole 36 of the lid cylinder portion 34. Here, an appropriate number of sharp-shaped projections 92 projecting downward from the lower surface 79 of the pressing plate portion 70 are formed on the pin 62 in the present embodiment. By pressing the pin 62, the bag bodies 90a and 90b are formed. Is broken by the protrusion 92, and the main agent 54a and the curing agent 54b accommodated therein are allowed to flow out. Thus, in this embodiment, the outflow means is configured including the protrusion 92.

  As a result, the main agent 54a and the curing agent 54b that have flowed out from the bags 90a and 90b are mixed, and a color different from that before the flow is developed and deposited on the step surface 40. Further, the main agent 54 a and the curing agent 54 b that do not completely enter between the pressing plate portion 70 and the step surface 40 by further pressing the pin 62 pass through the communication passage 78 formed between the notch 74 and the inner peripheral surface 51. Then, it is wrapped around the upper surface 76 of the pressing plate portion 70. In this way, as shown in FIG. 9B, the adhesive layer 80 that covers the entire pressing member 66 is formed, and the upper surface 76 of the pressing plate portion 70 is covered with the adhesive layer 80. According to this aspect, it is possible to configure the adhesive accommodating portion and the outflow means with a simpler configuration.

  Moreover, the principal part of the board | substrate case as 3rd embodiment of this invention is shown in FIG. As shown in FIG. 10 (a), the lid tube portion 34 in the present embodiment has a pair of bags each containing the main agent 54a and the curing agent 54b on the stepped surface 40, as in the second embodiment. Body 90a, 90b is provided. And especially in this embodiment, the one-way screw 94 is used as a stopper.

  The one-way screw 94 has a screw groove 97 formed on an upper surface 76 as an insertion operation end surface of a screw head 96 as a head, and a surface that receives a tool force when a tool such as a screwdriver is turned in a tightening direction is an axis. While the tool is raised in the direction to receive the force of the tool, when the tool is turned in the loosening direction, the surface that receives the force of the tool is tilted so that the force of the tool is released, thereby The screw is only allowed to rotate.

  Further, the inner peripheral surface of the pin insertion hole 42 in the lid cylinder portion 34 is a flat surface, while the pin insertion hole 25 in the main body cylinder portion 24 has a screw groove for screwing the leg portion 98 of the one-way screw 94. Is formed. Then, as shown in FIG. 10A, a one-way screw 94 is inserted from the leg 98 into the through hole 36 of the lid cylinder 34, and the leg 98 is inserted into the main body cylinder as shown in FIG. 10B. The 24 pin insertion holes 25 are screwed together.

  When the one-way screw 94 is inserted into the through hole 36 and the pin insertion hole 42, the screw head 96 crushes the bag bodies 90a and 90b. Thereby, the main agents 54a and 54b accommodated in the bag bodies 90a and 90b are caused to flow out. Here, the diameter dimension of the screw head 96 of the one-way screw 94 is made smaller than the diameter dimension of the head insertion hole 44 of the lid cylinder portion 34, and the screw head 96 and the inner peripheral surface 51 of the head insertion hole 44 are arranged. A predetermined gap 100 is formed between them. Further, when the one-way screw 94 is further pushed, a part of the main agent 54 a and the curing agent 54 b is wound around the upper surface 76 of the screw head 96 through the gap 100. Thus, in the present embodiment, the outflow means is configured including the screw head 96 and the flow path is configured including the gap 100.

  Then, as shown in FIG. 10C, the one-way screw 94 is inserted into the pin insertion hole 25 until the screw head 96 is locked by the stepped surface 40, so that the one-way screw 94 is fixed to the main body cylinder portion 24. At the same time, the stepped surface 40 of the cover cylinder part 34 is sandwiched between the screw head 96 and the upper surface of the main body cylinder part 24 so that the main body cylinder part 24 and the cover cylinder part 34 are fixed to each other. . Further, the screw head 96 is fixed to the lid tube portion 34 by the adhesive layer 80, and a part of the main agent 54 a and the curing agent 54 b is interposed between the one-way screw 94 and the pin insertion hole 25 by screwing the one-way screw 94. The one-way screw 94 and the pin insertion hole 25 are directly bonded to each other. Thereby, the main body cylinder part 24 and the cover cylinder part 34 are fixed more firmly. And according to this aspect, since the one-way screw 94 is screwed and rotated, the main agent 54a and the curing agent 54b can be stirred, and the color of the main agent 54a and the color of the curing agent 54b can be mixed. It can be done more effectively. Further, the adhesive layer 80 is wrapped around the upper surface 76 of the screw head 96 and enters the screw groove 97 of the screw head 96, so that the operation of the one-way screw 94 can be made more difficult.

  Next, FIG. 11 shows an essential part of a substrate case as a fourth embodiment of the present invention. In the present embodiment, an accommodation space 102 having a predetermined circumferential length is formed outside the through hole 36 in the lid cylinder portion 34, and an appropriate place on the circumference of the accommodation space 102 is A lid 104 is provided to be openable and closable. In particular, in the present embodiment, the lid 104 is guided by the guide groove 105 formed in the lid cylinder portion 34 and is movable in the vertical direction. The lid 104 is positioned upward due to a sliding contact resistance with the guide groove 105 or the like. A closed closed state and an open state positioned below can be selected. In the closed state of the lid 104, the accommodation space 102 is sealed, while in the opened state of the lid 104, the accommodation space 102 is opened on the inner peripheral surface 51 so as to communicate with the external space. It has become. Further, an action protrusion 106 that protrudes inward of the through hole 36 is integrally formed on the lid 104.

  Also, the adhesive 107 is accommodated in the accommodation space 102 with the lid 104 closed. As the adhesive 107, for example, a one-component type such as an epoxy type, an acrylic type, or a urethane type is used, and preferably has an extremely low viscosity in order to facilitate the flow in the communication path 78. Is used. Thus, the adhesive used in the present invention is not necessarily limited to the two-component type, and a one-component type can also be used. Furthermore, as shown in FIG. 12, microcapsules 110 containing a colorant 108 are mixed in the adhesive 107. In the present embodiment, a pigment is used as the colorant 108. In this case, the color of the colorant 108 accommodated in the microcapsule 110 is different from the color of the adhesive 107. In particular, in the present embodiment, the adhesive 107 is substantially colorless and transparent. The capsule 110 contains a blue pigment as the colorant 108.

  Then, when the pin 62 having the same structure as that of the first embodiment is inserted into the through hole 36 of the lid cylinder portion 34, the pressing plate portion 70 is brought into contact with the action protrusion 106 of the lid 104. It is done. Furthermore, the lid 104 is opened by the insertion operation of the pin 62, and the adhesive 107 accommodated in the accommodation space 102 is caused to flow out. As a result, as shown in FIG. 11B, an adhesive layer 80 that covers substantially the entire pressing plate portion 70 including the upper surface 76 is formed. Thus, in this embodiment, the outflow means is configured including the lid 104 and the pressing plate portion 70.

  Here, when the pin 62 is pushed in, the microcapsule 110 mixed in the adhesive 107 is crushed and the colorant 108 accommodated therein is caused to flow out of the microcapsule 110. As a result, the color of the adhesive 107 is changed and a color different from that before curing is developed in the adhesive layer 80. In the present embodiment, the adhesive 107 is substantially colorless and transparent, and the colorant 108 is blue, so that blue is developed in the adhesive layer 80. As is apparent from this embodiment, in order to change the color of the adhesive, not only the two liquid adhesives having different colors are mixed, but also the color of the one liquid adhesive is changed before and after the outflow. It may be changed with.

  Although several embodiments of the present invention have been described in detail above, these are merely examples, and the present invention should not be construed as being limited in any way by specific descriptions in these embodiments. Absent.

  For example, as a specific structure in which the adhesive that has flowed out of the adhesive container is changed to a color different from that before the flow by inserting the stopper, the one-pack type adhesive is applied to the bag body 90a shown in FIG. While being accommodated, a coloring agent may be accommodated in the bag 90b. Even in this case, the bag 90a, 90b is broken during the insertion operation of the pin 62, and the adhesive and the colorant are mixed, whereby the color of the adhesive can be changed.

  Alternatively, in the second embodiment shown in FIG. 9, in addition to the bag 90a containing the main agent 54a and the bag 90b containing the curing agent 54b, a colorant having a different color from the main agent 54a and the curing agent 54b is used. You may arrange | position the accommodated bag body in the location which can be destroyed in insertion operation of the pin 62, such as between the bag bodies 90a and 90b, for example. In this way, when the pin 62 is inserted, the bags 90a and 90b and the bag containing the colorant are destroyed, and the colorant is mixed with the main agent 54a and the curing agent 54b. Thereby, the color of an adhesive agent can be changed into a different color.

  Further, in the first embodiment, by mixing the pre-colored main agent 54a and the curing agent 54b, a color different from that before the outflow from the accommodation cavities 46a and 46b is expressed. However, for example, the main agent 54a and the curing agent 54b are made substantially colorless and transparent, and the microcapsules 110 as in the fourth embodiment are mixed in at least one of the main agent 54a and the curing agent 54b, so that the accommodation spaces 46a and 46b are contained. When the microcapsule 110 is broken by the pin 62 at the time of outflow from the main body, a color different from that before the outflow may be developed together with the mixing of the main agent 54a and the curing agent 54b.

  Further, as shown in FIG. 13, instead of the notch 74 formed in the pin 62 in the first embodiment, the through-hole penetrating in the thickness direction without opening outward in the radial direction of the pressing plate portion 70. A path 112 may be formed. In this way, the space between the pressing plate portion 70 and the inner peripheral surface 51 of the lid cylinder portion 34 can be formed without a substantial gap over the entire circumference, and the insertion of a tool into the gap can be further performed. While making it difficult, the sealing pin 52 in the first embodiment can be more reliably crushed.

  The specific structure of the stopper is not limited to the structure as in each of the above embodiments, and various conventionally known stoppers can be appropriately employed.

  Further, the position of the adhesive accommodating portion is not necessarily limited to the lid cylinder portion, and may be provided in the main body cylinder portion, or may be provided in both the main body cylinder portion and the lid cylinder portion. Also good. In each of the above embodiments, the adhesive is allowed to flow out from the adhesive accommodating portion using the head of the stopper, but the adhesive may be allowed to flow out using the leg of the stopper. Of course, it is possible. For example, in the second embodiment (see FIG. 9), the bag bodies 90 a and 90 b are formed with a diameter dimension substantially equal to the diameter dimension of the head insertion hole 44, and the bag bodies 90 a and 90 b are connected to the pins 62. They may be arranged on the step surface 40 so as to overlap in the insertion direction. In this way, when the pin 62 is inserted, the tip of the spring pin 64 serving as the leg breaks the bag bodies 90a and 90b, so that the adhesive can flow out.

  Furthermore, it goes without saying that the number and arrangement positions of the main body cylinder part and the cover cylinder part are not particularly limited. For example, in the above-described embodiment, four sets of the main body cylinder part and the cover cylinder part are provided, but it is also possible to provide more or less.

  The preferred technical idea of the present invention that can be understood from the above embodiment will be described below.

(1) A discharge path for allowing the adhesive to flow out is provided in the adhesive accommodating section, and a sealing section for sealing the discharge path is provided, and when the stopper is inserted, the sealing section is used with the stopper. The board case for a gaming machine according to any one of claims 1 to 3, wherein the outflow means is configured by destroying the board.

  In this way, the outflow means can be configured with a simple configuration. In order to make the adhesive flow out more smoothly, an air hole communicating with the external space is provided in the adhesive container together with the discharge path, and this air hole is inserted into the stopper in the same manner as the discharge path. Along with this, sealing may be performed in a breakable manner. For example, in the first embodiment, a discharge path is formed by the discharge hole 50, an air hole is formed by the air hole 48, and a sealing portion is formed by the sealing pin 52.

(2) The gaming machine substrate according to any one of claims 1 to 3, or the technical idea (1), wherein the outflow means is configured by providing a protrusion that pierces the adhesive accommodating portion in the stopper. Case.

  If it does in this way, at the time of insertion operation of a stopper, an adhesive can be made to flow out more easily by pressing a projection against an adhesive storage part and making a hole. For example, in the second embodiment, the protrusion 92 is formed on the lower surface 79 of the pressing plate portion 70 of the pin 62 so as to pierce the bag bodies 90a and 90b as the adhesive accommodating portion.

(3) The outflow means is configured by providing a lid in the adhesive accommodating portion so as to be opened and closed, and engaging the stopper with the lid by an operation of inserting the stopper to open the lid. Item 4. A gaming machine board case according to any one of Items 1 to 3 or the technical idea (1) or (2).

  If it does in this way, opening operation of an adhesive agent accommodating part can be performed more reliably. For example, in the fourth embodiment, the lid 104 can be opened and closed in the accommodation space 102 serving as the adhesive accommodating portion, and the pressing plate portion 70 acts on the projection of the lid 104 when the pin 62 is inserted. By engaging the portion 106, the lid 104 is opened.

(4) A discharge path for allowing the adhesive to flow out is provided in the adhesive accommodating portion, and the discharge path is positioned above an insertion operation end face of the stopper fixed in the inserted state. The board case for gaming machines according to any one of 1 to 3 or any one of technical ideas (1) to (3).

  In this way, since the adhesive is allowed to flow out from above the insertion operation end face of the stopper, the insertion operation end face can be more reliably covered with the adhesive. For example, in the first embodiment, the discharge hole 50 as a discharge path is opened on the inner peripheral surface 51 above the upper surface 76 of the pressing plate portion 70 of the pin 62 in the inserted state.
