Description

  The present invention relates to a control board case for a gaming machine that accommodates a control board of a gaming machine, and relates to a sealing structure that seals the case to prevent modification of the control board.

  As a sealing structure of a gaming machine control board case (hereinafter referred to as a control board case), one side wall of the cover is located on either the outer side or the inner side of the corresponding side wall of the base corresponding to the one side wall via a gap. The cover and the base are arranged so that the one side wall and the corresponding side wall are connected and fixed in the state having the gap, and the top of the cover is inserted to insert a cutting tool for the fixing member. An insertion port formed at a position above the gap of the wall, and a breakage portion provided in a state that can be broken at the insertion port and substantially closed the insertion port, and the breakage portion is broken. By doing so, there is known a device in which a cutting tool is inserted into the insertion port so that the fixing member can be cut halfway (for example, Patent Document 1).

Has been.

JP 2005-192792 A

  By the way, in the above-described conventional configuration, in order to release the sealing of the control board case, it is necessary to break the broken portion and insert the cutting tool into the insertion port. By checking, it can be confirmed that the seal has not been illegally released. However, in the configuration of Patent Document 1, a gap that is not covered with the rupture portion or a thin portion where the rupture portion is thin is provided on the outer peripheral edge of the insertion port in order to make the rupture portion easy to break. Yes. For this reason, in the case where there is a gap in the insertion port, if it is elongated such as a piano wire, the broken portion can be inserted into the insertion port without breaking. Moreover, even if there is no gap in the insertion port, a piano wire or the like can be inserted into the insertion port without leaving a conspicuous trace in the fractured portion by making a minute hole in the thin portion. For this reason, in the future, there will be a technique for improving fraudulent technology, in which a thin fraudulent tool is inserted into the insertion slot, the fixing member is cut without leaving a noticeable trace in the fracture portion, and the seal is illegally released. There is a possibility of development. In addition, there is a possibility that a technique of releasing the seal by pulling out from the side wall without damaging the fixing member by an unauthorized tool inserted into the insertion port may be developed. If the sealing of the control board case is illegally released by such a method, it will be difficult to detect the illegality if the sealing member is resealed by using a pulled-out fixing member or a duplicated fixing member.

  The present invention has been made in view of the present situation, and an object of the present invention is to propose a sealing structure of a control board case in which the case is not easily opened illegally as compared with the conventional configuration.

  The present invention is arranged in a control board case for a gaming machine that is assembled with a cover body that covers the front side of the control board and a base body that covers the back side of the control board, and seals the control board case for the gaming machine. A sealing structure having a first locking side wall provided on one side of the cover body, and a first locking wall provided on the base body so as to face the first locking side wall inward and outward. Two locking sidewall portions, a cutting gap formed between the first locking sidewall portion and the second locking sidewall portion, the first locking sidewall portion, A fixing member that engages both locking side walls and seals the control board case for gaming machines by penetrating the second locking side wall so as not to be removed, and an upper portion of the cutting gap A cover plate, and a shielding portion that vertically separates the cutting gap below the cover plate, the cover plate being broken A tool insertion opening substantially closed by an easy breaking portion, and the shielding portion has a tool passage opening substantially closed by an easy breaking portion below the tool insertion opening, and the fixing The member passes through the first locking side wall and the second locking side wall at least below the shielding portion, and inserts a cutting tool into the tool insertion port and the tool passage port. The sealing member is configured to release the sealing of the control board case for the gaming machine by cutting the fixing member in the cutting gap, and the lid plate is at least partially transparent, A sealing structure for a control board case for a gaming machine, wherein the breakage part of the shielding part is visible through a cover plate. Here, in the present invention, “upper” refers to the cover body side of the control board case, and “lower” refers to the base body side of the control board case.

  In such a configuration, when properly releasing the seal of the control board case, in order to insert the cutting tool to the lower part of the shielding part, to break the fracture part of the tool insertion opening and the tool passage opening, The tool insertion opening and the tool passage opening will be opened. On the other hand, in this configuration, not only the breakage portion of the tool insertion opening, but also the breakage portion of the tool passage opening is visible through the lid, so when the seal of the control board case is illegally released, It is necessary to completely cut the fixing member without leaving any conspicuous traces at the broken portions of the tool insertion opening and the tool passage opening. However, since the tool passage opening is covered with the cover plate and disposed at a position deep in the cutting gap, it is difficult to bring an unauthorized tool close to the fractured portion. Even if an unauthorized tool is inserted into the tool insertion slot on the cover plate in a way that the trace is not conspicuous, and the unauthorized tool is brought close to the tool passage opening, Because it is a cramped state that cannot be operated satisfactorily, even if an unauthorized tool inserted into the tool insertion port is further inserted into the tool passage port, traces remain at the fractured portion of the tool insertion port, and fraud I will be exposed. For this reason, according to the sealing structure of the present invention, it becomes more difficult to release the sealing without leaving a trace, and if the sealing structure on the control board case is adopted, unauthorized opening of the control board case can be reliably prevented. It becomes.

  In the present invention, the fixing member includes a plurality of fixing pins that pass through the first locking side wall and the second locking side wall so as not to be extracted, and the plurality of fixing pins. A part of which passes between the tool insertion opening and the tool passage opening and crosses the cutting gap, and the rest of the plurality of fixing pins passes under the tool passage opening and passes through the cutting gap. A configuration is proposed that traverses the cutting gap.

  In such a configuration, since the plurality of fixing pins of the fixing member are arranged separately above and below the tool passage port, the fixing pin disposed on the upper side of the tool passage port becomes an obstacle, so that the shielding portion is crafted. This makes it difficult to insert the unauthorized tool into the tool passage opening.

  Moreover, in the said structure, the structure by which the said tool insertion port, the said tool passage port, and these several fixing pins are arrange | positioned in the up-down direction is proposed.

  When the fixing member includes a plurality of fixing pins, it is necessary to cut all the fixing pins in order to release the sealing of the control board case. In such a configuration, since the rupture part to be ruptured and cut and the fixing pin are arranged in a vertical line, when releasing the seal, the rupture part of the tool insertion hole → the upper fixing pin → the rupture part of the tool passage opening → Breaking and cutting work can be performed efficiently by a series of flows in order from the top with the lower fixing pin. In particular, in this configuration, if the common tool is used at the time of breakage of the breakage portion and at the time of cutting the fixing pin, it becomes possible to release the sealing of the control board case more smoothly. For this reason, according to this configuration, even if a plurality of fixing pins are passed through the locking side wall portion, the seal release operation is not complicated.

  Further, in the present invention, the fixing member is formed by projecting the plurality of fixing pins in one direction on one side surface of the operation portion, and the other side surface of the operation portion is projected from the fixing pin. A configuration is proposed in which each fixing pin is passed through the first locking side wall and the second locking side wall by pressing in the direction.

  In such a configuration, the plurality of fixing pins can be simultaneously penetrated through the first locking side wall portion and the second locking side wall portion by pressing the operation portion of the fixing member once. Therefore, it is possible to firmly seal the control board case with a plurality of fixing pins without increasing the labor of the sealing work.

  Also, in the present invention, a configuration is proposed in which the breakage portion of the tool passage opening is more likely to break than the breakage portion of the tool insertion opening.

  In such a configuration, the tool passage opening can be easily opened by a normal seal release operation by the amount that the broken portion of the tool passage opening is easily broken, and when an unauthorized seal release is attempted. In addition, traces are likely to remain in the broken part, and fraud is easily revealed. The cover plate exposed outside the case must have a certain level of strength so that it will not be accidentally damaged by an external shock. Is not directly applied, the broken portion of the tool passage opening can be configured to be very easily broken.

  Further, in the present invention, the outer periphery of the tool insertion port and the tool passage port is formed with a gap that is not blocked by the fracture portion, and / or a thin portion where the fracture portion is thin, A configuration is proposed in which the tool insertion port and the tool passage port are formed so that their outer peripheral edges do not coincide vertically.

  The outer peripheries of the tool insertion opening and the tool passage opening in which the gap and the thin-walled portion are formed are portions where unauthorized tools can be relatively easily inserted, but in such a configuration, the tool insertion opening and the tool passage opening Since it arrange | positions so that an outer periphery may not correspond up and down, it becomes difficult to insert the unauthorized tool inserted through the clearance gap or thin part of the tool insertion slot to the back of the cutting gap. Specific methods for disabling the outer peripheries of the tool insertion opening and the tool passage opening vertically include shifting the outer peripheries and making the size and outer shape of the tool insertion opening and the tool passage opening different. To do.

  Another aspect of the present invention is a control board case for a gaming machine comprising a plurality of the sealing structures. The above sealing structure cannot be reused because the fixing member is cut when releasing the seal, but such a control board case can be repeatedly sealed and released as many as the number of sealing structures provided. In the gaming machine inspection, the control board case can be temporarily opened to check the control board.

  Another aspect of the present invention is a locking structure for locking the control board case for gaming machines to a mounting holder fixed to the gaming machine, and the mounting holder is inserted through the base body. A locking plate portion, and a bottom portion of the base body is provided with an insertion groove through which the locking plate portion is inserted in the vicinity of the second locking side wall portion. The stop plate portion includes an engagement hole through which the fixing member can not be extracted, and the lock plate portion inserted through the base body includes the first lock side wall portion and the second lock side portion. The fixing member that is arranged in parallel with the locking side wall and penetrates the first locking side wall and the second locking side wall further passes through the locking plate. Then, both the side wall portions for locking and the locking plate portion are engaged to seal the control board case for gaming machines. A locking structure for a game machine control board case, characterized in that locking the gaming machine control board casing to the mounting holder.

  Since such a locking structure is realized by using the sealing structure of the control board case, it can be realized by a simple configuration as compared with the case where the locking structure is provided alone. Also, with this configuration, the control board case can be sealed and locked to the mounting holder at the same time, and the control board case can be unlocked and the mounting holder can be unlocked at the same time. Therefore, the work can be simplified as compared with the case where each work is performed separately.

  As described above, according to the present invention, it becomes more difficult to release the sealing of the control board case without leaving a noticeable trace as compared with the conventional configuration. This can be prevented more reliably. Further, according to the locking structure of the control board case of the present invention, it is possible to simplify the sealing of the case, the locking to the mounting holder, and the releasing operation thereof.

Moreover, since the upper fracture | rupture part 63 is fractured | ruptured and the tool insertion port 62 will be in an open state after cancellation | release of a locked state, it will become possible to grasp | ascertain that the locked state of the 1st sealing structure 41a has already been cancelled | released. .

  As described above, the first sealing structure 41a can seal the control board case 7 by pressing the operation portion 47 of the fixing member 12 to be in the locked state. Here, since the fixing member 12 includes a plurality of fixing pins 48a and 48b, the cover body 10 and the base body 11 are formed by passing the fixing pins 48a and 48b through the locking side wall portions 42 and 43, respectively. Can be firmly engaged. On the other hand, the fixing pins 48a and 48b are arranged in parallel on the inner surface of the operation portion 47 and project in the same direction. Therefore, all the fixing pins 48a and 48b can be moved by pressing the operation portion 47 once. The first locking side wall portion 42 can be collectively penetrated. Therefore, according to such a configuration, the cover body 10 and the base body 11 can be firmly engaged with little effort.

  Further, the control board case 7 sealed by the first sealing structure 41a can be opened again by releasing the locked state of the first sealing structure 41a as described above. Here, in the locked state, as shown in FIG. 11, the tool insertion port 62, the tool passage port 65, and the two fixing pins 48a and 48b are arranged in a row so as to overlap each other. When the locked state of the one sealing structure 41a is released, (1) the upper broken portion 63 is broken, (2) the upper fixed pin 48a is cut, (3) the lower broken portion 66 is broken, and (4) the lower fixed pin is broken. The locked state can be efficiently released by cutting 48b and performing the breaking and cutting operations in order from top to bottom. In particular, in this embodiment, a nipper can be used for both the breaking of the breaking portions 63 and 66 and the cutting of the fixing pins 48a and 48b. Therefore, the breaking of the breaking portions 63 and 66 and the fixing pins 48a and 48b. By using a common tool for cutting, there is an advantage that the locked state can be released smoothly. Therefore, according to such a configuration, even when the cutting gap 44 is separated by the shielding portion 60 and the plurality of fixing pins 48a and 48b penetrate the locking side wall portions 42 and 43, the unlocking operation is performed. Is not complicated.

  On the other hand, when the control board case 7 sealed by the first sealing structure 41a is to be opened illegally, the locked state of the first sealing structure 41a is not left so as to prevent the unauthorized opening from being revealed. It is necessary to cancel. Here, in the first sealing structure 41a, not only the tool insertion port 62 but also the tool passage port 65 can be visually recognized through the transparent cover plate 56. As shown in FIG. 14, the tool is inserted into the cutting gap 44 without leaving any conspicuous traces in the breaking portions 63, 66 that close the tool insertion port 62 and the tool passage port 65, and the two fixing pins 48a, 48b must be cut. However, although the tool insertion port 62 is exposed at the upper part of the control board case 7 and is relatively easy to work with, the tool passage port 65 is covered with the cover plate 56 so that the cutting gap 44 is deepened. Therefore, it is difficult to bring an unauthorized tool close to the lower fracture portion 66. Even if an unauthorized tool can be inserted into the tool insertion port 62 of the cover plate 56 by a method in which traces are not conspicuous, an unauthorized tool inserted with the tool insertion port 62 hardly opened cannot be operated satisfactorily. In addition, since the upper fixing pin 48a that crosses between the tool insertion port 62 and the tool passage port 65 becomes an obstacle, the unauthorized tool is inserted into the tool passage port without leaving a noticeable trace in the lower fracture portion 66. It is impossible to insert the tool into the tool 65. If the tool is inserted into the tool passage port 65, the tool will be exposed. As described above, since the first sealing structure 41a is extremely difficult to release the locked state without leaving a noticeable trace, the first sealing structure 41a can reliably seal the control board case 7. It becomes.

  Further, in the first sealing structure 41 a, the thickness of the thin portion 67 of the lower fracture portion 66 is about half of the thin portion 64 of the upper fracture portion 63, and the lower fracture portion 66 is compared with the upper fracture portion 63. It is brittle and is easily broken. For this reason, when the locked state of the first sealing structure 41a is properly released, the lower broken portion 66 can be easily broken, while when the locked state is to be illegally released, the lower broken portion is broken. Since the portion 66 is fragile, there is an advantage that conspicuous traces are easily left and fraud is easily revealed. The upper fracture portion 63 is exposed at the upper portion of the case, whereas the lower fracture portion 66 is provided inside the cutting gap 44 and is not directly subjected to an impact from the outside. Even if the portion 66 is fragile and easily breaks, there is no possibility of being damaged by accidental impact.

  As described above, according to the first sealing structure 41a, the control board case 7 can be sealed and released by the same operation as the conventional sealing structure, while leaving no noticeable traces. It becomes more difficult to release the sealing of the control board case 7 as compared with the conventional configuration. For this reason, according to the first sealing structure 41a, it is possible to improve security without complicating the work of sealing and releasing the control board case 7.

Next, the configuration of the sealing structures 41b to 41d other than the first sealing structure 41a will be described.
As shown in FIGS. 9-11, the part which comprises each sealing structure 41a-41d in the left side part of the cover body 10 and the base body 11 is fundamentally the same shape, and seals other than the 1st sealing structure 41a The structures 41b to 41d have substantially the same configuration as the first sealing structure 41a, and have the same operational effects as the first sealing structure 41a. Specifically, the fourth sealing structure 41d disposed at the rear portion of the sealing device 40 has the same configuration as the first sealing structure 41a. On the other hand, the second sealing structure 41b and the third sealing structure 41c disposed in the center of the sealing device 40 have the same basic configuration as the first sealing structure 41a, but the second locking side wall 43 and the fixing member. The dimensions and arrangement of the holding frame 53 are slightly different from those of the first sealing structure. The second sealing structure 41b and the third sealing structure 41c have the same configuration.

  Here, the second sealing structure 41b and the third sealing structure 41c not only seal the control board case 7, but also lock the control board case 7 to the mounting holder 9b (see FIGS. 2 and 3) of the housing 2. It also functions as a locking structure. The second sealing structure 41 b will be described as an example. First, as shown in FIG. 10, a mounting holder is provided in the vicinity of the second locking side wall 43 in the left central portion of the bottom wall 30 of the base body 11. An insertion groove 33 through which 9b is inserted is opened. And in the 2nd sealing structure 41b, as shown to Fig.15 (a), the locking plate part 95 of the attachment holder 9b inserted in the case from the insertion groove 33 is the inner side of the side wall part 42 for 1st locking. In addition, the engagement holes 97, 97 that are arranged in parallel and formed in the locking plate portion 95 are configured to face the fixing pin through holes 50, 50 of the first locking side wall portion 42. . In addition, the fixing member 12 of the second sealing structure 41b has the fixing pins 48a and 48b longer than the first sealing structure 41a so as to be able to penetrate the mounting holder 9b. In addition, about the part which is the same structure as the 1st sealing structure 41a among the 2nd sealing structures 41b, a code | symbol is made common in a figure and description is abbreviate | omitted.

  Like the first sealing structure 41a, the second sealing structure 41b is operated by pressing the fixing member 12 so that the fixing pins 48a and 48b penetrate the first locking side wall portion 42, thereby locking the locked state from the pre-lock state. It becomes. Here, in the second sealing structure 41b, as shown in FIG. 15 (b), the locking plate portion 95 of the mounting holder 9b is adjacent to the inside of the first locking side wall portion 42. The fixing pins 48 a and 48 b penetrating through the locking side wall portion 42 pass through the engagement holes 97 and 97 of the locking plate portion 95 and cannot be removed from the locking plate portion 95. Therefore, in the locked state of the second sealing structure 41b, not only the locking side wall portions 42 and 43 are engaged and the control board case 7 is sealed, but also the both locking side wall portions 42 and 43 are attached. By engaging the holder 9b, the control board case 7 is locked to the mounting holder 9b. Further, the locked state of the second sealing structure 41b can be released by opening the tool insertion port 62 and the tool passage port 65 and cutting the fixing pins 48a and 48b in the same manner as the first sealing structure 41a. . When the locked state of the second sealing structure 41b is released, the sealing of the control board case 7 is released and the locking of the control board case 7 to the mounting holders 9a and 9b is released.

  Thus, in the present embodiment, the second sealing structure 41b and the third sealing structure 41c also function as a locking structure for locking the control board case 7 to the mounting holders 9a and 9b. There is an advantage that the locking structure can be simplified. Moreover, in these sealing structures 41b and 41c, the control board case 7 can be sealed and locked to the mounting holder 9b at the same time by simply pressing the fixing member 12 into the locked state. By simply releasing the locked state, the seal release of the control board case 7 and the unlocking of the mounting holders 9a and 9b can be simultaneously performed. For this reason, in this embodiment, there is an advantage that each work can be made more efficient than the case where the sealing / locking work of the control board case 7 and the releasing work thereof are performed in separate procedures.

  In the present embodiment, the four sealing structures 41a to 41d provided in the sealing device 40 are provided when the control board 8 is accommodated, mounted on the slot machine 1, when inspected by a supervisory agency, and when the control board 8 is installed. Used in order at the time of collection. Specifically, the control board case 7 is sealed by first locking the first sealing structure 41a when the control board 8 is accommodated in the manufacturing process. Then, the sealed control board case 7 is transported as it is and attached to the housing 2 of the slot machine 1 via the attachment holders 9a and 9b. Here, when the control board case 7 is attached to the housing 2, the control board case 7 is locked to the housing 2 by bringing the second sealing structure 41 b into a locked state. Then, after the control board case 7 is attached to the housing 2, if it is necessary for the supervisory organization to confirm that the regular ROM is mounted on the control board 8, the first sealing structure 41 a and the second sealing structure 41 a The locked state of the two-sealing structure 41b is released. As a result, the control board case 7 can be removed from the housing 2 and opened, and the control board 8 can be checked. After checking the control board 8, the control board case 7 is closed and attached to the attachment holders 9a and 9b of the housing 2, and the third sealing structure 41c is brought into a locked state. As a result, the control board case 7 is resealed and re-engaged with the housing 2, and the slot machine 1 can be continuously used in a state where the control board 8 is prevented from being illegally used. After that, when the control board 8 is recovered, the locked state of the third sealing structure 41c is released and the fourth sealing structure 41d is set to the locked state. Thereby, the control board case 7 can be removed from the housing 2 and transported while the sealed state of the control board case 7 is maintained.

  Thus, each sealing structure 41a-41d of the sealing device 40 cannot be reused once the locked state is released, but in this embodiment, by using these sealing structures 41a-41d in order, The control board case 7 can be resealed or re-engaged with the housing 2.

  The present invention is not limited to the embodiment described above, and various modifications can be made without departing from the scope of the present invention.

  FIG. 16 is a modification in which the configuration of the tool insertion port 62 and the tool passage port 65 is changed from the above embodiment. As apparent from comparison with FIG. 11, in this modification, the tool insertion port 62 and the tool passage port 65 are arranged slightly shifted in the plate surface direction of the cover plate 56 and the shielding portion 60, and the respective outer peripheral edges are arranged. Is configured so that the thin portions 64 and 67 formed along the respective outer peripheral edges do not overlap each other. In such a modification, even when an unauthorized tool can be inserted into the tool insertion port 62 via the thin wall portion 64, the thin wall portion 67 of the tool passage port 65 does not exist immediately below the tool insertion port 62, so that no noticeable trace remains. It becomes even more difficult to insert the unauthorized tool into the tool passage opening 65. In this modification, the tool insertion port 62 and the tool passage port 65 are arranged so as to be shifted so that the thin portions 64 and 67 do not overlap. However, the tool insertion port 62 and the tool passage port 65 are not overlapped. Even when the sizes and shapes of the two are different, it is possible to prevent the thin-walled portions and the gaps on the outer peripheral edge from overlapping each other. Specifically, the tool insertion port 62 may be made larger than the tool passage port 65, or one of the tool insertion port 62 and the tool passage port 65 may be rectangular and the other may be elliptical.

  Further, in the modification shown in FIG. 16, the fixing member 12 of the first sealing structure 41a is disposed so that the fixing pins 48a and 48b overlap with each other, whereas the other sealing structures 41b to 41d are fixed. The members 12a to 12c are arranged so as to be shifted in the front-rear direction of the control board case 7 so that the fixing pins 48a and 48b do not overlap vertically. As described above, when the fixing pins 48a and 48b are arranged to be shifted, the lower fixing pin 48b can be easily seen from above the control board case 7, and the state of each of the fixing pins 48a and 48b can be easily grasped. Become. In this modification, as shown in FIG. 16, the fixing members 12, 12a to 12c of the sealing structures 41a to 41d are different in the displacement widths of the upper and lower fixing pins 48a and 48b. The fixing pin through holes are formed in the locking side walls (not shown) of ˜41d according to the shift widths of the corresponding fixing pins 48a and 48b. Thus, in this modification, since the arrangement of the fixing pins 48a and 48b and the fixing pin through holes is different for each of the sealing structures 41a to 41d, the dedicated fixing members 12, 12a to 12c are provided for each of the sealing structures 41a to 41d. It must be used, making it difficult to produce a replica of the fixed member. For this reason, in such a modified example, it is difficult to perform an illegal act of cutting the fixing member, opening the control board case, and resealing using a replica of the fixing member.

  Moreover, in the said Example, although the cover body 10 comprised the cover plate 56 and the base body 11 comprised the shielding part 60, as shown to Fig.17 (a), the base body 11 changed the cover plate 56 into. And the cover body 10 may constitute the shielding part 60. Also, as shown in FIG. 17B, one of the cover body 10 and the base body 11 is both the cover plate 56 and the shielding part 60. You may make it comprise. Moreover, in the said Example, although the side wall part 42 for 1st latching of the cover body 10 was arrange | positioned inside, the side wall part 43 for 2nd latching of the base body 11 was arrange | positioned outside, FIG.17 (b). As shown, the first locking side wall portion 42 may be disposed on the outer side, and the second locking side wall portion 43 may be disposed on the inner side.

  In addition, the fixing member according to the present invention is not limited to the configuration in which the two fixing pins 48a and 48b are provided as in the above-described embodiment. For example, the fixing member may have three or more fixing pins. Good. Further, the configuration of the fixing pin is not limited to a rod-like body having a barb 49 formed at the tip end, and may be any shape that penetrates the locking side walls 42 and 43 so as to be removable, and is provided on the fixing member. It is not necessary for each fixing pin to have the same shape. As shown in FIG. 17C, the operation portion 47 of the fixing member 12 is not limited to a plate-like body, and may have a rounded shape. The fixing member 12 may be a fixing member holding frame 53. It does not matter if it is not held. Moreover, like the sealing structure described in Patent Document 1, the fixing member can be integrally formed with the cover body or the base body, or can be fixed to the cover body or the base body.

  Moreover, although the fracture | rupture parts 63 and 66 of the said Example are the structures by which the thin part 64 and 67 was provided in the outer periphery, the shape of the fracture | rupture part which concerns on this invention changes suitably not only in the structure of an Example. It is possible. For example, like the fracture | rupture parts 63a and 66a shown in FIG. 18, the whole can also be made thin. Moreover, like the fracture | rupture parts 63b-63d shown in FIG. 18, the clearance gap 68 is formed in the outer periphery of the tool insertion port 62, and the fracture | rupture parts 63b-63d are made into the tool insertion port via the narrow connection part 69. It is good also as a structure connected with the periphery of 62. FIG. Moreover, the clearance gap 68 of the outer periphery of the tool insertion port 62 shown in FIG. 18 can also be changed into a thin part.

  Moreover, the control board case 7 of the said Example comprises four sealing structures 41a-41d based on this invention, However, The number of the sealing structures provided in the control board case 7 can be changed suitably. . In this case, the respective sealing structures may have the same configuration or may have completely different configurations. In the above embodiment, the second sealing structure 41b and the third sealing structure 41c also serve as a locking structure for locking the control board case 7 to the mounting holder 9b. The locking structure can be provided separately from the sealing structure. For example, in the 2nd sealing structure 41b and the 3rd sealing structure 41c of the said Example, the fixing member 12 is comprised so that both the side walls 42 and 43 for locking and the locking plate part 95 may be penetrated. (See FIG. 15), the configuration of the sealing structures 41b and 41c is changed so that the fixing member 12 penetrates one of the locking side walls 42 and 43 and the locking plate 95. By doing so, it is possible to obtain a locking structure for locking the control board case 7 to the mounting holder 9b without sealing the control board case 7.

  Moreover, in the said Example, although the cover body 10 and the base body 11 are comprised with transparent resin, the cover body and base body which concern on this invention can permeate | transmit a cover plate and can visually recognize the fracture | rupture part of a shielding part. If it is a structure, other parts may be opaque. For example, in order to facilitate confirmation from the outside, the breakage portion and the fixing member may be colored with a conspicuous color. Moreover, although the said Example demonstrated the control board case 7 which accommodates the control board 8 of the slot machine 1, this invention is not restricted to this structure, The control board case of other game machines, such as a pachinko game machine, is demonstrated. The type of control board to be accommodated is not particularly limited.
