Description

  The present invention relates to a gaming machine member configured by assembling a plurality of members to each other by engagement, and a gaming machine including the gaming machine member.

  Gaming machines can be subject to various cheating activities. For example, a main control board is accommodated in the housing of the gaming machine, and a storage device (usually a ROM) in which a program for controlling the gaming machine is recorded is mounted on the main control board. However, there is known an illegal act of replacing this storage device with a forged one (so-called forged ROM). In order to prevent this type of fraud, each manufacturer of gaming machines has a structure in which an electronic board such as a main control board is housed and sealed in a case (a board case for gaming machines). The specific form of the board case for gaming machines varies depending on the type of electronic board accommodated therein and the installation location thereof, but a cover member that covers the upper surface side of the electronic board and a base that covers the lower surface side of the electronic board. The thing provided with the member is common.

  In this type of gaming machine substrate case, the cover member and the base member are usually sealed by engaging an engaging portion provided on one member with an engaged portion provided on the other member. It has a structure. The gaming machine substrate case is fixed to a gaming machine chassis via a chassis member such as a case holder. Even when the board case for gaming machines is assembled to the housing side member, it is usually sealed by engaging the engaging portion provided on one member with the engaged portion provided on the other member. Structure is adopted.

  By the way, in the gaming machine industry, the regular engagement between the cover member and the base member in a factory or the like is called “A caulking”, and the portion of the gaming machine substrate case to which “A caulking” is applied is “ It is called “A staking part”. Further, in a factory or the like, the regular engagement of the gaming machine substrate case with the housing side member such as the case holder is called “B caulking”, and the “B caulking” in the gaming machine substrate case and the housing side member is called “B caulking”. The portion to be applied is called “B caulking portion”. As will be described later, the “B caulking portion” is a portion that is assumed to be normally opened at the time of inspection by an inspection organization. Again, when assembling to the chassis side member, the regular engagement of the gaming machine board case with the chassis side member is called “C caulking”, and the “C caulking” in the gaming machine board case and the chassis side member is called “C caulking”. "Is called" C caulking part ".

  As described above, in a gaming machine member such as a board case for gaming machines provided with a “B caulking part” or a “C caulking part”, the “B caulking part” and the “C caulking part” usually have independent structures. The “B caulking portion” and the “C caulking portion” are each provided with an engaging portion and an engaged portion (for example, FIGS. 2 and 3 and paragraph 0065 in Patent Document 1). However, until now, one of the engaging portion and the engaged portion constituting the “B caulking portion” is not affected by the engagement function of the “B caulking portion”. It has also been proposed that the part can be reused as an engaging part or an engaged part of the “C caulking part” by making the structure separable from the above. When this structure is adopted, there is an advantage that the number of parts of the parts constituting the “B caulking part” and the “C caulking part” can be suppressed.

Japanese Patent Laid-Open No. 2004-136078

  However, as described above, one part of the “B-caulking part” can be separated from the “B-caulking part”, and the part can be reused as an engaging part or an engaged part of the “C-caulking part”. If it is possible to do so, the portion separated from the “B-caulking portion” after the “B-caulking portion” is normally opened until the “C-caulking portion” is sealed is a board case for gaming machines. Also, there is a problem in that it is completely separated from the housing side member, and only that portion can be carried independently. For this reason, there is a possibility that the portion may be replaced with a counterfeit product that can be easily disengaged between the time when the “B crimping portion” is normally opened and the time when the “C crimping portion” is sealed.

  The present invention has been made in order to solve the above-described problems. The engaged portion constituting one “crimping portion”, such as “B crimping portion”, is replaced with another “C crimping portion”, etc. Not only can it be reused as an engaged part that constitutes the “crimping part”, but the engaged part is removed from the original member such as a board case for a gaming machine or a housing side member and is not carried independently. By adopting a structure, a gaming machine member having an improved effect of preventing illegal acts is provided. It is also an object of the present invention to provide a gaming machine provided with this gaming machine member.

The above issues
A gaming machine comprising a first member and a second member that are assembled together by engagement to seal a gaming machine substrate or to attach a gaming machine substrate case sealing the gaming machine substrate to a housing side member A member for
The first member is
An engaged movable body movable between a first position and a second position;
A movable body holding portion for holding the engaged movable body in a state where it cannot be removed from other parts of the first member unless the first member is destroyed;
While having
The second member is
The first position at which the tip is engaged with the engaged movable body by pushing the engaged movable body at the first position in a direction non-parallel to the direction connecting the first position and the second position. Engaging portion;
A second position at which the tip is engaged with the engaged movable body by pushing the engaged movable body at the second position in a direction non-parallel to the direction connecting the first position and the second position. Engaging portion;
This is solved by providing a member for a gaming machine characterized by comprising:

By adopting such a configuration,
The engaged portion with which the first position engaging portion engages and the engaged portion with which the second position engaging portion engages are reused with one engaged portion (engaged movable body), Not only can the number of parts of the first member be reduced to reduce manufacturing costs,
The engaged portion (movable body for engagement) is removed from the other part of the first member (main body portion of the first member) and is not carried independently from the main body portion (the engaged portion is It is also possible to have a structure that does not walk alone.
Accordingly, it is possible to prevent an illegal act such as replacing the engaged portion (the engaged movable body) with a counterfeit product that can be easily disengaged.
The configuration according to the present invention can be particularly preferably employed in the portions called “B caulking” and “C caulking” that are engaged when the gaming machine board case is assembled to the chassis side member.

  By the way, in this specification, the positional relationship of each part is the first position engaging part or the second position engaging part and the engaged movable body, unless otherwise noted, such as “when ...”. The state after the engagement (the state after the first member and the second member are assembled) is described as a reference. For example, in the following description, “the first member and the second member surround the engaging portion including the first position engaging portion, the second position engaging portion, the engaged movable body, and the movable body holding portion. The description of “covered” and “the breaking portion at the time of normal opening is formed in the first member or the second member covering the base end side of the first position engaging portion or the second position engaging portion” However, these descriptions mean that after assembling the first member and the second member, each part has such a positional relationship, and the first member and the second member It does not prescribe the positional relationship of each part before assembling.

In the gaming machine member of the present invention,
The first member and the second member cover the periphery of the engaging portion including the first position engaging portion, the second position engaging portion, the engaged movable body, and the movable body holding portion.
Unless the first member or the second member is destroyed, it is preferable to prevent access to the engagement site.

By adopting such a configuration,
In addition to making unauthorized access to the engagement sites (first position engagement portion, second position engagement portion, engaged movable body and movable body holding portion) more difficult,
The engagement portion can be in a state surrounded by a member (first member or second member) provided with the engagement structure (a state where the engagement portion is sealed by the member including the engagement structure), It is also possible to seal the engaging portion without separately using a member other than the first member and the second member (for example, a dedicated member for covering the engaging portion).

As a specific structure for covering the periphery of the engagement portion with the first member and the second member, for example,
The second member is a gaming machine substrate case for sealing the gaming machine substrate,
The first member is a case holder whose rear side is fixed to the gaming machine housing and to which the board case for gaming machines is attached on the front side,
The movable body holding portion is arranged at a location where the rear surface side is covered with the rear wall portion of the case holder (first member),
While arranging the first position engaging portion and the second position engaging portion at the location where the front side is covered with the front wall portion of the gaming machine substrate case (second member),
The upper, lower, left, and right sides of the engagement portion are the upper wall portion, the lower wall portion, the left wall portion, and the right wall portion of the case holder (first member) or the board case for gaming machines (second member). The structure etc. which are arranged in the location covered are illustrated.

  In the gaming machine member of the present invention, when the periphery of the engagement portion is covered by the first member and the second member, the normal opening breakage portion formed weaker than the surroundings for the purpose of breaking at the time of normal opening Is preferably formed in a portion of the first member or the second member that covers the base end side of the first position engaging portion or the second position engaging portion.

By adopting such a configuration, the inspection machine of the gaming machine can engage the first position engaging part or the second position engaging part with the engaged movable body for the purpose of inspecting the gaming machine substrate. When unlocking (when opening properly), destroy the normal opening breakage part, insert a tool such as a nipper from the broken part, and engage the first position engagement part or the second position engagement part If the base end portion is cut or the like, the engagement between the first position engaging portion or the second position engaging portion and the engaged movable body can be released. In other words, as long as the breaking part at the time of normal opening and the engaging part for the first position or the engaging part for the second position are destroyed, the other parts (particularly the movable body to be engaged) are not damaged, and for gaming machines. The member can be easily opened normally. Therefore, the first member and the second member can be properly opened without causing damage that significantly lowers the sealing function, and the first member and the second member are again engaged after the regular opening. When resealing, the original first member and second member can be reused without replacement.
In addition, in the case of unauthorized opening, it is possible to make the trace remain in the breaking portion at the time of normal opening, and to make the gaming machine member more difficult to illegally access.

In the gaming machine member of the present invention,
The engaged movable body has a positioning fitting portion,
The movable body holder is
A first position fitted portion that engages with the positioning fitting portion when the engaged movable body is in the first position;
A second position fitted portion that engages with the positioning fitting portion when the engaged movable body is in the second position;
It is also preferable to have

By adopting such a configuration,
When the first member and the second member are assembled, an appropriate position (first position or second position) at which the movable body to be engaged can be engaged with the first position engaging section or the second position engaging section. Not only can it be moved and held at that position,
When carrying the first member to which the second member is not assembled, it is possible to prevent the engaged movable body from rattling and being damaged.

Furthermore, in the gaming machine member of the present invention,
Move the movable body holder
A holding body,
A holding unit occlusion body;
Consisting of
Hold the holder body
An internal space for accommodating the movable body for engagement in a movable state between the first position and the second position;
In the movable body to be engaged accommodated in the internal space, a portion to be exposed to the outside of the holding portion main body is engaged with the first position engaging portion and the second position engaging portion. An opening for engaging portion exposure;
A movable body accommodating opening for accommodating the engaged movable body in the internal space from the outside of the holding body;
On the other hand,
Holding part occlusion body,
It is also possible to close the opening for accommodating the movable body by fitting from the side opposite to the side on which the second member is assembled as viewed from the first member to the place where the holding portion main body is provided in the first member. preferable.

The reason why it is preferable to adopt this configuration is as follows.
That is, in the gaming machine member of the present invention, the movable body to be engaged is held against the movable body holding portion in a state where it cannot be removed from the other parts of the first member unless the first member is destroyed. The adoption of the structure to be used has already been described. As this structure, for example, the movable body holding portion is constituted by a holding portion main body and a holding portion closing body made of different members, and the holding portion is held by holding the movable body to be engaged with the holding portion main body. By assembling the holding part closing body to the main body and fixing it by bonding or the like, a structure can be mentioned in which the movable body for engagement is pressed by the holding part closing body so as not to be pulled out from the holding part main body.

  However, in this type of structure, the entire boundary line between the holding portion main body and the holding portion closing body is the front side of the first member (the first position engaging portion or the second position engaging portion of the second member). If the structure appears on the side where the movable body is held, a cutting tool such as a cutter is inserted into the boundary line from the front side of the movable body holding part, and the movable body holding part is cleaned along the boundary line. After cutting and disassembling the holding part main body and the holding part closing body, removing the engaged movable body and replacing it with a counterfeit, the holding part main body and the holding part closing body are bonded along the boundary line, etc. When cheating is done, there is no noticeable trace and it may be difficult to notice the cheating.

  In this regard, the holding unit closing body is fitted from the side opposite to the side where the second member is assembled as viewed from the first member (rear side) with respect to the location where the holding unit main body of the first member is provided. By adopting such a configuration, it becomes possible to prevent the entire boundary line between the holding part main body and the holding part closing body from appearing on the front side of the first member. In addition, it is possible to make the joint surface (welded surface, adhesive surface, etc.) between the holding portion main body and the holding portion closing body intricately complicated in three dimensions. Therefore, it is very difficult to cleanly disassemble the movable body holding portion using a tool such as a cutter in the operation from the front side of the first member.

Furthermore, in the gaming machine member of the present invention,
The second member shall have a weakened portion formed weakly,
It is also preferable that the base end portions of the first position engaging portion and the second position engaging portion are integrally provided on one surface side of the fragile portion.

  By adopting such a configuration, when the first position engaging portion or the second position engaging portion is pulled out from the engaged movable body, plastic deformation such as whitening remains in the fragile portion. Becomes possible, and it becomes easy to detect fraud.

In the gaming machine member of the present invention, when the first position engagement portion and the second position engagement portion are provided integrally with the weak portion formed in the second member,
At least one of the first position engaging portion and the second position engaging portion is referred to as a direction perpendicular to the one surface of the fragile portion (hereinafter referred to as “β direction”). called "beta ⁺ side" and the side farther from the one surface, a side close to the one surface of the weak portion in the beta direction. "beta ^- side" hereinafter) to the beta arranged at a predetermined distance ⁺ side It is composed of an engaging part and a β ^- side engaging part,
When the tip of the first position engaging portion or the second position engaging portion engaged with the engaged movable body is pulled out from the engaged portion, the β ^- side engaging portion is engaged. It is also preferable that the engaging surface of the β ⁺ side engaging portion contacts the engaged surface of the engaged movable body before the surface contacts the engaged surface of the engaged movable body. .

  By adopting such a configuration, when the first position engagement portion or the second position engagement portion is to be pulled out from the engaged movable body (the first position engagement portion or the second position engagement portion). The first position is derived from the tensile force applied from the engaged movable body to the first position engaging portion or the second position engaging portion when the engagement between the engaged movable body and the engaged movable body is released. It is possible to increase the moment generated in the vicinity of the boundary between the engaging portion for the second position or the engaging portion for the second position and the fragile portion, and to easily cause plastic deformation such as whitening in the fragile portion. In addition, it is possible to increase the engagement strength between the first position engaging portion or the second position engaging portion and the engaged movable body. Therefore, in the case of unauthorized access, it is possible to make the trace more likely to remain in the vulnerable part and its peripheral part.

When the distal end of the first position engaging portion or the second position engaging portion is to be pulled out from the engaged portion, the engaging surface of the β ^- side engaging portion is engaged with the engaged movable body. Prior to abutting on the mating surface, as a specific structure in which the engaging surface of the β ⁺ side engaging portion abuts on the engaged surface of the engaged movable body,
beta ⁺ side engagement portion of the engagement surface and the beta ^- structure and providing the step (step in pushing direction of the engaging portion) between the mating surfaces of the side engaging portions,
In the engaged movable member, and beta ⁺ side engaging portion beta ⁺ side the engagement surface engaging surface is engaged in, beta ^- beta engaging surface of the side engaging portion are engaged ^- side the The structure etc. which provide a level | step difference (step difference in the pushing direction of an engaging part) between engagement surfaces are illustrated.

Moreover, in the member for voluntary gaming machines of the present invention,
The first member or the second member illegally releases the engagement between the first position engaging portion and the engaged movable body, or the second position engaging portion and the engaged movable body. It is also preferable to provide a thermal reaction part that changes the appearance by heating in the whitening part at the time of fraud release that can be whitened.

  In gaming machine members such as board cases for gaming machines, even when whitening occurs due to unauthorized access, there are cases in which traces of unauthorized access are erased by heating and making the whitened part transparent. It has been reported that by adopting such a configuration, it is possible to visually confirm the heating history of the portion. Therefore, it is possible to make it more difficult to illegally release the engagement without leaving a trace.

The cover member 110 is assembled to the front side of the base member 120, and the electronic substrate 500 is housed in the gaming machine substrate case 100.
[Resealing procedure 3]
A gaming machine substrate case 100 is assembled to the front side of a case holder 200 (a case side member) fixed to the front side of the back plate 10a ₁ (FIG. 2) of the main body 10a.
[Resealing procedure 4]
A protective cover 300 is assembled to the front side of the gaming machine substrate case 100.

  Hereinafter, the resealing procedures 1 to 4 will be described.

5.1 Resealing procedure 1
In the resealing procedure 1, the electronic substrate 500 after inspection is assembled on the rear surface side of the cover member 110 in the same procedure as the assembling procedure 1 described above.

5.2 Resealing procedure 2
In the resealing procedure 2, the cover member 110 is assembled on the front side of the base member 120 in the same procedure as the assembling procedure 2 described above. However, when performing the above assembly procedure 2, the engaging portion 170 constituting the “A crimping portion” is engaged with the engaged portion 130, but when performing the resealing procedure 2 In the regular opening procedure 3 described above, the “A caulking portion” is destroyed, and the “A caulking portion” cannot perform its function. For this reason, in the resealing procedure 2, the “A crimping portion” is not engaged. After the regular opening procedure 3 is performed, the “A caulking portion” remains in a destroyed state.

5.3 Resealing procedure 3
In the resealing procedure 3, the same procedure as the assembling procedure 3 described above is applied to the front side of the case holder 200 (the casing side member) fixed to the front side of the back plate 10a ₁ (FIG. 2) of the casing body 10a. Then, the gaming machine substrate case 100 is assembled. In this resealing procedure 3, the gaming machine substrate case 100 is assembled to the case holder 200 in a state where it cannot be removed from the case holder 200 unless the gaming machine substrate case 100 and the case holder 200 are destroyed. .

  In this regard, when performing the above assembling procedure 3, as shown in FIG. 17, the engaging portion 170 (first position engaging portion) constituting the “B caulking portion” is moved to the first position (FIG. 40 (a)) is engaged with the engaged movable body 220. However, when the resealing procedure 3 is performed, the engagement portion 170 of the “B crimping portion” is destroyed in the regular opening procedure 2 described above, and the function (B crimping) cannot be performed. . For this reason, in the resealing procedure 3, the engagement portion 170 of the “B-caulking portion” and the movable body 220 to be engaged are not engaged, and the engagement provided in the engagement portion 170 of the “B-caulking portion” is provided. The mating portion 170 (the engaging portion 170 at the portion indicated by the symbol “C” in FIG. 17) (second position engaging portion) is moved to the engaged movable body 220 at the second position (FIG. 40B). Is engaged. Therefore, when performing the resealing procedure 3, the engaged movable body 220 is moved to the second position in advance. The engagement state between the second position engaging portion 170 and the engaged movable body 220 is the same as the engagement state between the first position engaging portion 170 and the engaged movable body 170 (FIGS. 15 to 17). Therefore, the description is omitted.

  By the way, in the gaming machine industry, when reassembling the gaming machine board case removed from the housing side member (case holder 200, etc.) at the time of regular opening by an inspection engine or the like to the original housing side member, Engaging the gaming machine board case with the chassis side member is called “C caulking”, and the portion of the gaming machine board case and the chassis side member where “C caulking” is applied is called “C caulking part”. I'm calling. The “C caulking part” prevents the gaming machine board case from being illegally removed from the chassis side member after the regular opening by the inspection organization or the like (the gaming machine board case has been illegally removed from the chassis side member). (Sometimes so that the traces remain).

  In the present embodiment, the engaging portion 170 (second position engaging portion) and the engaged movable body 220 engaged in the resealing procedure 3 are also provided as the “C crimping portion”. (However, as described above, the engaged movable body 220 is also used as the “B crimping portion”). Therefore, in this specification, the engagement between the engaging portion 170 engaged in the resealing procedure 3 and the engaged movable body 220 is referred to as “C caulking”. The portion engaged by the engaging portion 170 and the engaged movable body 220 may be referred to as a “C crimping portion”. In the drawings of the present application, a portion corresponding to the “C caulking portion” is indicated by using a symbol “C”.

  The engagement portion 170 (second position engagement portion) constituting the “C crimping portion” is not particularly limited as long as it is a location where unauthorized access is difficult in the gaming machine substrate case 100 or the like. However, the engaging portion 170 constituting the “C caulking portion” is connected to the first position engaging portion 170 in the vicinity of the engaging portion 170 (first position engaging portion) constituting the “B caulking portion”. It is preferable to provide them in parallel (so that their mutual engaging directions are parallel). As a result, when the “caulking part” to be used is switched from “B caulking part” to “C caulking part”, the engaged movable body 220 may be moved by a short distance along a simple trajectory (linear trajectory). As a result, the case holder 200 can be easily designed. Further, the number of “C caulking sections” installed is not particularly limited. In this embodiment, as shown in FIG. 15 and FIG. 16, the “C caulking portion” ( One second position engaging portion) is provided.

  By the way, since the regular opening by the inspection institution or the like is not limited to once, in the case of a conventional board case for gaming machines, in addition to the “C caulking part”, the “D caulking part” and the “E caulking part” May be provided. In this case, the “C crimping portion” is destroyed at the second regular opening, the “D crimping portion” is used at the second resealing, and the “C crimping portion” is used at the third regular opening. The “D-caulking portion” is destroyed and the “E-caulking portion” is used for the third reseal. In the gaming machine substrate case 100 and the case holder 200 of this embodiment, a portion corresponding to the “D caulking portion” or the “E caulking portion” is not provided, but the gaming machine substrate case 100 and the case holder 200 include A portion corresponding to “D caulking portion” or “E caulking portion” can also be provided.

  When the “D crimping portion” or the “E crimping portion” is provided, the engaged movable body 220 is used as the “B crimping portion” and the second position is used as the “C crimping portion”. It is possible to move not only to the position but also to the third position used as the “D caulking part” and the fourth position used as the “E caulking part”, and to be engaged at the third position. This can be realized by providing a third position engaging portion that engages with the combined movable body 220 and a fourth position engaging portion that engages with the engaged movable body 220 at the fourth position. In this case, it is preferable that the first position engaging portion, the second position engaging portion, the third position engaging portion, and the fourth position engaging portion be arranged close to each other in parallel.

  When the engaging portion 170 (second position position engaging portion) of the “C crimping portion” and the movable body 220 to be engaged are engaged in the above procedure, the resealing procedure 3 is completed. In this state, although the “C crimping portion” for engaging the gaming machine substrate case 100 and the case holder 200 is functioning, the cover member 110 and the base member 120 in the gaming machine substrate case 100 are engaged. As described above, the “A caulking portion” that has been destroyed is not functioning as the “A caulking portion”.

  However, the board case 100 for gaming machines of this embodiment has a structure in which the cover member 110 cannot be removed from the base member 120 unless the cover member 110 is slid upward with respect to the base member 120 (the above-mentioned regularity). However, the case holder 200 has an upper wall portion 204 as shown in FIG. 14, and when the resealing procedure 3 is finished, the upper wall portion 204 is covered with the cover member 110. Is pushed from above, and the upward sliding of the cover member 110 is restricted. Therefore, when the gaming machine substrate case 100 is assembled to the case holder 200, the cover member 110 cannot be removed from the base member 120 even if the “A crimping portion” is not functioning. Yes.

5.4 Resealing Procedure In the resealing procedure 4, the protective cover 300 is assembled on the front side of the gaming machine substrate case 100 in the same procedure as the assembling procedure 4.

5.5 After Completion of Reseal Procedures 1 to 4 When all of the above reseal procedures 1 to 4 are completed, the gaming machine is ready to be installed in the hall. When a suspicious behavior is seen in the gaming machine installed in the hall, or when a failure or a suspicious point is recognized in the electronic board 500, the electronic board 500 or the like is returned to the manufacturer.

6). Manufacturer Return Procedure for Electronic Substrate etc. When returning the electronic substrate 500 of this embodiment to the manufacturer, it is assumed that the following return procedures 1 to 4 are performed.
[Return procedure 1]
The protective cover 300 is removed from the front side of the gaming machine substrate case 100.
[Return procedure 2]
The above-mentioned “C crimping portion” is released, and the board case 100 for gaming machines is removed from the case holder 200.
[Return procedure 3]
The cover member 110 and the base member 120 in the gaming machine substrate case 100 are engaged with each other by using an “F crimping portion” to be described later, and the electronic substrate 500 is sealed in the gaming machine substrate case 100.
[Return procedure 4]
The electronic substrate 500 is returned to the manufacturer while being sealed in the gaming machine substrate case 100.

  Hereinafter, the return procedures 1 to 4 will be described.

6.1 Return procedure 1
In the return procedure 1, the protective cover 300 is removed from the front side of the gaming machine substrate case 100 in the same procedure as the regular opening procedure 1 described above.

6.2 Return procedure 2
In the return procedure 2, the “C-caulking portion” is released in the same procedure as that for releasing the “B-caulking portion” in the regular opening procedure 2 described above, and the gaming machine substrate case 100 is removed from the case holder 200. However, when releasing the “B-caulking portion” in the regular opening procedure 2 described above, the normal-opening destruction portion 100a ₁ (FIG. 9) provided in the portion covering the “B-caulking portion” in the gaming machine substrate case 100. ), And a tool such as a nipper is inserted from the broken portion to cut the engagement portion 170 of the “B-caulking portion”. When releasing the “C-caulking portion” in the return procedure 2, The normal opening breaking portion 100a ₂ (FIG. 9) provided in the portion covering the “C caulking portion” in the machine substrate case 100 is broken, and a tool such as a nipper is inserted from the broken portion to obtain the “C caulking portion” ”Is cut.

  In the state where the return procedure 2 is completed, the board case 100 for gaming machines is removed from the case holder 200, and the upper wall portion 204 (FIG. 14) of the case holder 200 restricts the sliding of the cover member 110 upward. In addition to being ineffective, since the “A crimping portion” has already been destroyed and no longer functions as described above, the cover member 110 can be removed from the base member 120. .

6.3 Return procedure 3
As described above, when the return procedure 2 is completed, the cover member 110 is in a state where it can be removed from the base member 120. For this reason, the gaming machine substrate case 100 in this state cannot fulfill the sealing function of the electronic substrate 500. Therefore, if the gaming machine substrate case 100 is returned to the manufacturer in this state, if the illegal action such as replacing the ROM of the electronic board 500 with a counterfeit ROM is made in the middle of the return route, It becomes difficult to notice. Also, even if the manufacturer inspects the returned electronic board 500 and finds fraudulent acts such as replacement of counterfeit ROMs, the fraudulent acts were done in the hall or in the middle of the return route It becomes difficult to judge whether it is a thing. Therefore, in this return procedure 3, the cover member 110 and the base member 120 are reengaged, and the electronic substrate 500 is again sealed by the gaming machine substrate case 100.

  In this embodiment, the engaged portion 180 (see FIG. 31 described later) provided near the lower right corner of the base member 120 is separated from the base member 120 using a nipper or the like, and the separated portion is separated. The engaged portion 180 is fitted from above into the engaged portion insertion port 110b provided at the right end portion of the upper wall portion 114 of the cover member shown in FIG. The cover member 110 is assembled to the base member 120 by performing the same operation (backward movement operation and downward sliding operation) as that of the cover member 110 being assembled to the base member 120 in the assembling procedure 2. The member 110 and the base member 120 are engaged again. When the cover member 110 is slid downward, the engagement portion 170 provided at the upper right corner of the base member 120 (the engagement portion 170 indicated by the symbol “F” in FIG. 7A) is provided. Then, it is pushed into and engaged with the engaged portion 180 described above. Since the engaged portion 180 has a configuration in which a flange is provided around the engaged portion 180 and cannot pass through the engaged portion insertion port 110b, the engaged portion 170 is engaged with the engaged portion 180. After joining, the cover member 110 cannot be removed from the base member 120 unless the engaged portion 180 and the engaging portion 170 engaged therewith are destroyed.

  At this time, the section of the base member 120 where the engaged portion 180 (FIG. 31) is cut is in a state where a hole (cutout hole) is opened. However, in the gaming machine substrate case 100 of the present embodiment, the partition wall portion 126 of the base member 120 (see FIG. 30A described later) and the partition wall portion 116 of the cover member 110 (see FIG. 21 described later). (b)), the space inside the gaming machine substrate case 100 that communicates with the outside through the cut-out hole is separated from the space in which the electronic substrate 500 is accommodated. For this reason, unless the partition wall portion 116 and the partition wall portion 126 are destroyed, the electronic substrate 500 cannot be accessed through the cutout hole.

  By the way, in the gaming machine industry, when returning an electronic board or the like to a manufacturer, engaging the cover member and the base member in the board case for the gaming machine that accommodates the electronic board or the like is called “F-caulking”. In the gaming machine substrate case, a portion to which “F caulking” is applied is called an “F caulking portion”. The “F-caulking section” prevents the gaming machine board case from being illegally opened when returning the electronic board or the like to the manufacturer (the trace remains when the gaming machine board case is opened illegally). To become) part.

  In the present embodiment, the engaging portion 170 and the engaged portion 180 engaged in the return procedure 3 are also provided as the “F crimping portion”. Therefore, in this specification, the engagement between the engaging portion 170 and the engaged portion 180 engaged in the return procedure 3 is referred to as “F caulking”, and this engagement in the board case 100 for gaming machines A portion engaged by the portion 170 and the engaged portion 180 may be referred to as an “F crimping portion”. In the drawings of the present application, a portion corresponding to the “F crimping portion” is indicated by using a symbol “F”.

  The “F-caulking portion” is not particularly limited as long as it is a location where it is difficult for unauthorized access to the gaming machine substrate case 100. In addition, the number of “F caulking sections” is not particularly limited. In this embodiment, as shown in FIGS. 8 and 9, an “F caulking portion” is provided at one place in the upper right corner of the gaming machine substrate case 100. The “F-caulking portion” is not provided with a part of the structure (for example, the push displacement restricting portion 140 and the proximity displacement restricting portion 150 shown in FIG. 24 described later) existing in the “A caulking portion” or the like. Except this, it is the same as “A caulking part” or the like. For this reason, detailed description is omitted about the mode of engagement of the “F crimping portion”. When the engagement of the “F crimping portion” is completed, the return procedure 3 ends.

6.4 Return procedure 4
In the return procedure 4, the electronic board 500 and the like are returned to the maker together with the gaming machine board case 100 through a predetermined return path.

6.5 After completion of return procedures 1 to 4 The manufacturer cancels the “F-caulking portion” in the board case 100 for gaming machines returned from the hall, etc., and applies to the base member 120 in the same manner as the regular opening procedure 3 described above. After the cover member 110 is slid upward, the cover member 110 is pulled out forward to remove the cover member 110 from the base member 120, and then the electronic substrate 500 is mounted in the same procedure as the regular opening procedure 4 described above. The cover member 110 is removed and the electronic substrate 500 is inspected and repaired. The release of the “F-caulking portion” destroys the normal opening destruction portion 100a ₃ (FIG. 7A) provided in the portion covering the “F-caulking portion” in the board case 100 for gaming machines, and the destroyed portion. This is performed by inserting a tool such as a nipper and cutting the engaging portion 170 of the “F crimping portion”.

7). Specific structure of gaming machine board case and peripheral members thereof The gaming machine board case of the present embodiment is the above-mentioned "3. Assembly procedure of gaming machine board case", "4. gaming machine board case, etc." Because it is assumed to be used as described in “Regular opening procedure of”, “5. Resealing procedure of board case for gaming machine” and “6. Manufacturer return procedure of electronic board”, etc. The substrate case 100, the case holder 200, and the like are provided with various devices suitable for such usage. Hereinafter, these devices will be described in detail.

However, in the following explanation, for convenience of explanation, the terms “α direction”, “α ⁺ side” and “α ⁻ side”, and “β direction”, “β ⁺ side” and “β ⁻ side” are used. May be used. The meaning of these phrases is as shown in FIG. FIG. 35 shows that the engaged portion of the engaging portion 170 provided as the “A crimping portion” on the base member 120 is pushed into the engaged portion 130 provided as the “A crimping portion” on the cover member 110. It is the figure which looked at the mode of the displacement of the engaging part 170 when pushing in the direction back side and making it engage from the back side (z-axis direction positive side) of the pushing direction.

That is, it is perpendicular to the pushing direction (z-axis direction) of the engaging portion 170 with respect to the engaged portion 130 and is on the surface of the fragile portion 100b ₁ (the surface on the side where the engaged portion 130 is provided; the same applies hereinafter). and call direction parallel to the "alpha direction", one side of the alpha direction is referred to as "alpha ⁺ side", the other side of the alpha direction ^- is called "alpha side". In the example of FIG. 35 (A caulking), x-axis direction positive side has become a "alpha ⁺ side", x-axis direction negative side ^- are "alpha side". Further, the direction perpendicular to the plane of the fragile portion 100b ₁ is called a "beta direction", the side far from the surface of the fragile portion 100b ₁ of the beta direction is referred to as "beta ⁺ side" fragile portion 100b ₁ of the beta direction The side close to the surface is called the “β ^- side”. In the example of FIG. 35 (A caulking), y-axis direction positive side has become a "beta ⁺ side", y-axis direction negative side ^- are "beta side".

The terms “α direction”, “α ⁺ side” and “α ⁻ side” and “β direction”, “β ⁺ side” and “β ⁻ side” mean other than “A caulking part”. The same applies to the “B caulking part” and the “C caulking part”. However, in this embodiment, since the pushing direction of the engaging portion 170 is different between the “A crimping portion”, the “B crimping portion”, and the “C crimping portion”, the “α direction” and the like, The relationship between the axis, the y-axis and the z-axis is also different. Specifically, in the “B caulking portion” and the “C caulking portion”, the z-axis direction shown in FIG. 16 is the “α direction”, the z-axis direction positive side is the “α ^- side”, and the z-axis direction negative side is “Α ⁺ side”.

In addition, in the “A caulking portion”, as shown in FIG. 13, the fragile portion 100b ₁ is provided on the engaged portion 130 side, and the positive side in the y-axis direction is the “β ⁺ side” (fragile portion 100b ₁ in the far side) from, y-axis direction negative side "beta ^- side" (whereas has a side close) the fragile portion 100b _1, in the "B caulking portion" and "C caulking portion" 18 as shown in the fragile portion 100b ₁ is provided in the engagement portion 170 side, y-axis direction positive side is "beta ^- side" in (closer to the weak portion 100b _1), y-axis direction negative side "beta ⁺ Side ". Thus, "beta ⁺ side" and the "A caulking portion" reversed and ^{- -} "side beta" and "beta side", "beta ⁺ side" in "B crimping portion" and "C crimping portion" and Therefore, be careful. This point will be described in detail later.

In the present embodiment, as will be described later, the “B caulking portion” and the “C caulking portion” are also provided with the weak portion 100b ₁ (FIG. 17). The same applies to the fragile portion 100b ₁ in which the normal direction is substantially parallel to the front-rear direction (y-axis direction).

As already mentioned, for a game machine board case 100 of this embodiment, via the case holder 200 is attached to the back plate 10a ₁ of the housing body 10a (FIG. 2). Therefore, as shown in FIG. 2, when the gaming machine substrate case 100 is attached to a predetermined location of the chassis body 10a (gaming machine chassis), the front wall portion 111 of the cover member 110 is positioned forward. It is arranged so as to face (the negative side in the y-axis direction in FIG. 2). In addition, as shown in FIG. 2, when the front door 10b of the gaming machine housing is opened, the front wall portion 111 of the cover member 110 opens the open surface 10a ₂ (opens the front door 10b) of the housing body 10a. The surface opened by this (refer to the surface indicated by the alternate long and short dash line in FIG. 2). In other words, between the front wall portion 111 (the board case for a game machine 100) and the open face 10a ₂ of the housing body 10a, in a state of absence of obstacles like blocking the line of sight. Therefore, as described above, the weak portion 100b ₁ provided on the front wall portion 111 of the cover member 110 can be easily visually recognized by the inspector.

In this way, by not interposing an obstacle that blocks the line of sight between the member providing the fragile portion 100b ₁ (whitening portion at the time of fraud release) and the open surface 10a ₂ of the housing body 10a, the fragile portion 100b ₁ ( It becomes possible for the inspector to easily confirm the fraud release whitening portion). This also applies to the case where the configuration according to the present invention is employed in other members (members other than the main control board unit 30; for example, the sub control board unit 31 in FIG. 2) attached to the housing body 10a. is there. Further, when the configuration according to the present invention is employed in a member (for example, the liquid crystal unit 32 or the connector unit 34 in FIG. 2) attached to the front door 10b instead of the housing body 10a, the weakened portion 100b ₁ ( A member that provides a fraud release whitening portion and an open surface 10b _{2 of the} front door 10b (a surface that overlaps with the open surface 10a ₂ of the housing body 10a when the front door 10b is closed. This is indicated by a two-dot chain line in FIG. By not interposing an obstacle that obstructs the line of sight between them, the inspector can easily confirm the weakened portion 100b ₁ (whitening portion at the time of fraud release). The normal direction of the fragile portion 100b ₁ (the whitening portion at the time of fraud cancellation) is set to be substantially parallel to the normal direction of the open surface 10a ₂ of the housing main body 10a (the fragile portion 100b ₁ ( If provided illegal cancellation whitened part).), or, prior to substantially the normal direction of the open surface 10b ₂ of the door 10b to be parallel (front door 10b side of the member to the fragile portion 100b ₁ (illegal cancellation When a whitening portion) is provided, it is preferable.

A method for forming the fragile portion 100b ₁ more fragile than the peripheral portion is not particularly limited. In this embodiment, weak portion 100b _1, by forming thinner than portions of the periphery thereof, forms brittle than the surrounding site, the plastic deformation of the whitening such that portion is likely to occur. Engaging in the present specification, as in the above fragile portion 100b _1, the gaming machine member provided (not only the cover member 110 and base member 120 also includes other members such as case holder 200.) Improper engagement between the engaging portion and the engaged portion around the portion, the engaged portion, or the portion of the gaming machine member where the engaging portion or the engaged portion is provided A portion that undergoes plastic deformation such as whitening upon release may be referred to as a “whitening portion at fraud release”.

The thickness of the fragile portion 100b ₁ is different depending on the molding material of the cover member 110, etc., it is not particularly limited. However, if the fragile portion 100b ₁ is made too thick, there is a possibility that a trace will hardly remain in the fragile portion 100b ₁ at the time of unauthorized access. Therefore, the thickness of the fragile portion 100b ₁ is preferably When 1mm or less, and more preferably when the 0.7mm or less, more preferably to 0.5mm or less. On the other hand, an excessively thin fragile portion 100b _1, not only the time of the unauthorized access, when engaged with the regular engaging portion 170 in the manufacturing plant or the like of the gaming machine with respect to the engaged portion 130 (above the set even when) performing with Step 2, the plastic deformation is likely to occur in the fragile portion 100b _1. Therefore, the thickness of the fragile portion 100b ₁ is generally a 0.05mm or more. The thickness of the fragile portion 100b ₁ is more preferable to set 0.1mm or more.

Further, the area of each fragile portion 100b ₁ (the area of one fragile portion 100b ₁ ) is not particularly limited. However, when each of the too narrow area of the fragile portion 100b _1, inevitably, the engaged portion 130 also becomes necessary to reduce, there is a possibility that molding of such engaged portion 130 becomes difficult. Therefore, the area of each of the fragile portion 100b ₁ is preferably When 5 mm ² or more, and more preferably to 10 mm ² or more. On the other hand, if the area of each fragile portion 100b ₁ is too large, the fragile portion 100b ₁ is easily damaged, and plastic deformation is likely to occur in the fragile portion 100b ₁ even in cases other than unauthorized access. . For this reason, it is preferable to provide the fragile portion 100b ₁ in a limited range. Specifically, each of the area of the weakened part 100b _1, preferably when the 300 mm ² or less, more preferably when the 200 mm ² or less, more preferably to 100 mm ² or less. If you can not too small dimensions of the engaged portion 130, so that the cover member 110 of the present embodiment, per one of the engagement portions 130, may be provided to divide the weakened portion 100b ₁ at a plurality of locations.

As long as the engaged portion 130 can engage the engaging portion 170 provided on the base member 120 side (the engaging portion 170 of the portion indicated by reference numeral “A” in FIG. 31 described later), The form is not particularly limited. In the cover member 110 of the present embodiment, as shown in FIG. 33 to be described later, the engaging portion 170 is set to the α ⁺ β ⁺ side engaging portions 172 and α located on the α ⁺ side (x-axis direction positive side). ⁺ beta ^- the side engaging portions 173, alpha ^- side located at (x-axis negative direction side) alpha ^- beta ⁺ side engaging portion 174 and the alpha ^- beta ^- because it consists of a side engaging portion 175, As shown in FIGS. 24 and 25, the engaged portion 130 on the cover member 110 side also includes an α ⁺ side engaged wall portion 131 disposed on the α ⁺ side (the positive side in the x-axis direction), and the α ⁻ side. α arranged to (x-axis direction negative side) ^- are constituted by the side the engagement wall portion 132. That is, the α ⁺ β ⁺ side engaging portion 172 and the α ⁺ β ⁻ side engaging portion 173 are engaged with the α ⁺ side engaged wall portion 131, and the α ⁻ side engaged wall portion 132 is engaged with α ^−. The β ⁺ side engaging portion 174 and the α ⁻ β ⁻ side engaging portion 175 are engaged.

When the engaging portion 170 is pushed into and engaged with the engaged portion 130, the α ⁺ side (x axis direction positive side) α ⁺ β ⁺ side engaging portion 172 and α ⁺ β ⁻ side engagement The portion 173 receives a pressing force from the α ⁺ side engaged wall portion 131, and the α ⁻ β ⁺ side engagement portion 174 and the α ⁻ β ⁻ side engagement portion 175 on the α ⁻ side (x axis direction negative side) The pressing force is received from the α ^- side engaged wall portion 132. Therefore, when the engaging portion 170 is pushed into the engaged portion 130 and engaged, as shown in FIG. 35, α ⁺ β ⁺ side engagement on the α ⁺ side (x axis direction positive side) The portion 172 and the α ⁺ β ⁻ side engaging portion 173, and the α ⁻ side (x-axis direction negative side) α ⁻ β ⁺ side engaging portion 174 and the α ⁻ β ⁻ side engaging portion 175 of FIG. From the initial position indicated by the solid line portion to the first displacement position indicated by hatching in the same figure, after elastically moving in the direction of approaching each other in the α direction (x-axis direction), the elastic position is restored to the initial position again. , Α ⁺ side engaged wall portion 131 and α ⁻ side engaged wall portion 132 are engaged.

Further, as shown in FIG. 24B, the engaged portion 130 of the present embodiment includes a front end portion (rear end portion) of the α ⁺ side engaged wall portion 131 and an α ⁻ side engaged wall. A connecting wall portion 133 that connects the front end portion (rear end portion) of the portion 132 is also provided. Further, the engaged portion 130 is connected to the base end portion (front end portion) of the α ⁺ side engaged wall portion 131 and the base end portion (front end portion) of the α ⁻ side engaged wall portion 132. A bottom wall 134 is also provided. For this reason, as shown in the front view of FIG. 25, the engaged portion 130 has a front view frame shape and is in a state in which the rigidity is increased. Therefore, it is possible to prevent the engaging portion 170 from being detached from the engaged portion 130 due to unintended deformation of the engaged portion 130 engaging the engaging portion 170.

  Further, in the cover member 110 of the present embodiment, as shown in FIG. 11, the load bearing wall is located at a position on the front side (z-axis direction negative side) of the engaging portion 170 when viewed from the load bearing wall 114. The indentation displacement restricting portion 140 is provided in a state spaced from the portion 114 by a predetermined interval. When the engaging portion 170 is pushed into and engaged with the engaged portion 130, the indentation displacement restricting portion 140 is displaced toward the back side in the pushing direction (the positive side in the z-axis direction) and contacts the load bearing wall 114. By being in contact therewith, it becomes a part for regulating the displacement of the engaged portion 130 thereafter to the back side in the pushing direction (positive side in the z-axis direction). More specifically, the indentation displacement restricting portion 140 is a portion for exhibiting the following functions.

That is, as already described, the engaged portion 130 is integrated with the fragile portion 100b ₁ in order to easily leave a trace when the engaging portion 170 engaged with the engaged portion 130 is illegally pulled out. when provided, this is fragile portion 100b _1, not only at the time of tampering when engaging the engagement portion 170 in a manufacturing factory or the like of the gaming machine to the normal with respect to the engaged portion 130 (of the When performing the assembling procedure 2), traces such as whitening may remain. This is because when the engaging portion 170 is pushed and engaged with the engaged portion 130, the pushing force by the engaging portion 170 is also applied to the engaged portion 130, and the engaged portion 130. This is because attempts to displace the pushing direction rear side (z-axis positive direction side) with respect to weakened portion 100b _1. For this reason, if no countermeasures are taken against the above-described problem, there is a possibility that the gaming machine substrate case 100 that has not been tampered with is misidentified as having been tampered with.

In this respect, in the gaming machine substrate case 100 of the present embodiment, the above-described indentation displacement restricting portion 140 is provided, so that when the engaging portion 170 is pushed into the engaged portion 130 and engaged, to regulate the displacement of the pushing direction inner side of the engaging portion 130 (z-axis direction positive side), the displacement of the pushing direction rear side of the engaged portion 130 for fragile portion 100b ₁ (z-axis positive direction side) It can be made smaller. Therefore, when the engaging push the engagement portion 170 with respect to the engaged portion 130, it becomes difficult to excessive force is applied to the fragile portion 100b _1, resulting plastic deformation of whitening or the like vulnerable portion 100b ₁ It is possible to make it difficult.

On the other hand, when the engaging portion 170 is pulled out of the engaged portion 130 and the engagement between the engaging portion 170 and the engaged portion 130 is to be released, the above-mentioned push displacement restricting portion 140 is not engaged. Since it is displaced together with the portion 130 toward the front side in the pushing direction (the negative side in the z-axis direction) and does not come into contact with other parts such as the load-bearing wall portion 114, The function of restricting the displacement of the engaged portion 130 toward the front side in the pressing direction is not exhibited. For this reason, when the engaging portion 170 is illegally pulled out from the engaged portion 130, whitening or the like of the fragile portion ₁₀₀ b ₁ (occurrence of illegal release trace) is not hindered by the indentation displacement restricting portion 140.

In the gaming machine substrate case 100 of the present embodiment, the above-described pushing displacement restricting portion 140 is provided in the above manner so that when the engaging portion 170 is pushed into the engaged portion 130, the fragile portion 100b. _Although it is difficult for plastic deformation such as whitening to occur in FIG. ₁ , when the engaging portion 170 is pulled out from the engaged portion 130, a seemingly contradictory purpose is to easily cause plastic deformation such as whitening in the fragile portion ₁₀₀ b _1. Has been achieved successfully.

The indentation displacement restricting portion 140 is formed on the cover member 110 at a position on the near side in the pushing direction of the engaging portion 170 (the z-axis direction negative side in FIG. 11) when viewed from the load bearing wall 114. If it is provided integrally (provided in a state of being displaced together with the engaged portion 130), the specific installation location is not limited. The indentation displacement restricting portion 140 is directly pressed by the engaging portion 170 (the pushing force of the engaging portion 170 is directly applied from the engaging portion 170 to the indentation displacement restricting portion 140), thereby pushing in the pushing direction. The engagement portion 170 may not be directly pressed (the pushing force of the engagement portion 170 may cause the α ⁺ side engaged wall portion 131 or α ⁻ in the engaged portion 130 to be displaced). It may be configured to be indirectly added to the push displacement restricting portion 140 via the side engaged wall portion 132 or the like.

As shown in FIG. 24A, the push displacement restricting portion 140 of the present embodiment is provided in a portion extending on the far side in the push direction (z axis direction positive side) in the connecting wall portion 133 of the engaged portion 130. It is a convex part. The indentation displacement restricting portion 140 is in a state of protruding to the side where the engaging portion 170 is inserted (the negative side in the y-axis direction). For this reason, as shown in FIG. 12, when the engaging portion 170 is pushed into the engaged portion 130, the surface of the end portion on the front side in the pushing direction (z-axis direction negative side) in the pushing displacement restricting portion 140. 140a (hereinafter, sometimes referred to as “the engaging portion contact surface of the push-in displacement restricting portion”) on the β ⁺ side (y axis direction positive side) of the engaging portion 170 (α in FIG. 33). ⁺ Β ⁺ side engaging portion 172 and α ⁻ β ⁺ side engaging portion 174) come into contact with each other. Therefore, the behavior of the α ⁺ β ⁺ side engaging portion 172, the α ⁻ β ⁺ side engaging portion 174, and the push displacement restricting portion 140 when the engaging portion 170 is pushed into the engaged portion 130 is stabilized. Is possible.

Further, in this embodiment, as shown in the left side view of FIG. 24A and FIG. 25, the engaging portion contact surface 140a of the push-in displacement restricting portion 140 is set to the front side in the push direction (z in FIG. 24). It is inclined so as to protrude from the β ^- side (y-axis direction negative side in FIG. 24) from the negative side in the axial direction to the back side in the pushing direction (positive side in the z-axis direction in the figure). Therefore, when the engaging portion 170 is pushed into the engaged portion 130 and engaged, the α ⁺ β ⁺ side engaging portion 172 and the α ⁻ β ⁺ side engaging portion 174 are shown by the solid line in FIG. After being displaced from the initial position indicated by the portion to the first displacement position indicated by hatching in the same figure, by further abutting and being guided by the engaging portion contact surface 140a of the push displacement restricting portion 140, After elastically displacing to the β ^- side (y-axis direction negative side) up to the second displacement position indicated by the broken line portion in FIG.

That is, in the gaming machine substrate case 100 of the present embodiment, when the engaging portion 170 is pushed into the engaged portion 130 and engaged, the α ⁺ β ⁺ side engaging portion 172 and the α ⁻ β ⁺ side are engaged. The engaging portion 174 is elastically displaced in both the α direction (x-axis direction) and the β direction (y-axis direction). As described above, the engagement structure of the α ⁺ β ⁺ side engaging portion 172 and the α ⁻ β ⁺ side engaging portion 174 and the engaged portion 130 is complicated, thereby engaging the engaged portion 130. It is possible to make it more difficult to illegally remove the engaging portion 170 from the engaged portion 130.

As shown in FIG. 13, after engaging the engaging portion 170 with the engaged portion 130, a portion on the β ⁺ side (y axis direction positive side) of the engaging portion 170 (α ⁺ β in FIG. 33). ⁺ side engaging portion 172 and alpha ^- in the gap beta ⁺ side engaging portion 174), push displacement regulating portion 140 is adapted to position. For this reason, even if the α ⁺ β ⁺ side engaging portion 172 and the α ⁻ β ⁺ side engaging portion 174 are intended to be displaced toward each other in the α direction (x-axis direction) for the purpose of illegally releasing the engagement. The indentation displacement restricting portion 140 is in the way. That is, it is possible to cause the indentation displacement restricting portion 140 to perform the same function as the proximity displacement restricting portion 150 described later.

The size of the gap G ₁ (FIG. 11) between the indentation displacement restricting portion 140 and the load bearing wall 114 is not particularly limited. However, if too large the gap G _1, when engaged by pushing the engagement portion 170 with respect to the engaged portion 130, push displacement regulating portion 140 disappears into contact with the bearing wall portion 114, the indentation depth There is a possibility that the restricting portion 140 cannot restrict the displacement of the engaged portion 130 toward the back side in the pushing direction. Therefore, the gap G _{1 (the} gap G _1, etc. If there are engaged portion protection member 160 to be described later, when there is a separate member in the gap G ₁ is excluding the thickness of the separate members The value is the same hereinafter.) Is usually 3 mm or less. The gap _{G 1} is preferable to be 2mm or less, and more preferably 1mm or less.

Further, in the present embodiment, as shown in FIG. 24B, the proximity displacement restriction is applied to a portion of the bottom wall portion 134 of the engaged portion 130 that extends to the back side in the pushing direction (the z-axis direction positive side). The part 150 is provided in a convex shape. The proximity displacement restricting portion 150 is in a state of projecting to the side where the engaging portion 170 is inserted (the positive side in the y-axis direction). For this reason, as shown in FIG. 13, after engaging the engaging portion 170 and the engaged portion 130, the β ^- side (y-axis direction negative side) portion of the engaging portion 170 (α in FIG. 33). ⁺ beta ^- side engaging portion 173 and the alpha ^- beta ^- in the gap of the side engaging portions 175), proximate the displacement restricting portion 150 comes to the position. That is, even if the α ⁺ β ⁻ side engaging portion 173 and the α ⁻ β ⁻ side engaging portion 175 are to be displaced toward each other in the α direction (x-axis direction) for the purpose of illegally releasing the engagement, The proximity displacement restricting section 150 becomes an obstacle.

As shown in FIG. 12, when the engaging portion 170 is pushed into the engaged portion 130, a surface 150 a (hereinafter referred to as an end portion) of the proximity displacement restricting portion 150 on the near side in the pushing direction (the z-axis direction negative side) The engagement portion 170 comes into contact with the “engagement portion contact surface of the proximity displacement restricting portion”. In this respect, in this embodiment, as shown in the left side view of FIG. 24B and FIG. 25, the engaging portion contact surface 150a of the proximity displacement restricting portion 150 is set to the front side in the pushing direction (in FIG. 24). It is inclined so as to protrude from the β ⁺ side (y-axis direction positive side in FIG. 24) from the z-axis direction negative side to the push-in direction back side (z-axis direction positive side in the figure). Therefore, when the engaging portion 170 is pushed into and engaged with the engaged portion 130, the α ⁺ β ⁻ side engaging portion 173 and the α ⁻ β ⁻ side engaging portion 175 are shown by the solid line in FIG. After being displaced from the initial position indicated by the portion to the first displacement position indicated by hatching in the same figure, by further abutting and guiding the engaging portion contact surface 150a of the proximity displacement restricting portion 150, After elastically displacing to the β ⁺ side (y axis direction positive side) up to the second displacement position indicated by the broken line portion in FIG. 35, the elastic return is made to the initial position. That is, in the gaming machine substrate case 100 of this embodiment, when the engaging portion 170 is pushed into the engaged portion 130 and engaged, the α ⁺ β ⁺ side engaging portion 172 and the α ⁻ β ^{+ are} engaged. In addition to the side engaging portion 174, the α ⁺ β ⁻ side engaging portion 173 and the α ⁻ β ⁻ side engaging portion 175 are also elastic in both the α direction (x axis direction) and the β direction (y axis direction). It is designed to be displaced. Thus, by complicating the engagement structure between the engaging portion 170 and the engaged portion 130, the engaging portion 170 engaged with the engaged portion 130 is illegally removed from the engaged portion 130. Can be made even more difficult.

Incidentally, in the gaming machine board case 100 of this embodiment, as inspector of the presence or absence of unauthorized access is easily visually fragile portion 100b _1, when placing the gaming machine board case 100 in the housing of the gaming machine to, and arranged so that the normal direction of the fragile portion 100b ₁ is a line-of-sight direction of the inspector substantially parallel. Thus, in a game machine circuit board case 100 and the like, a vertical plate-like portion fragile portion 100b ₁ (e.g., above or bearing wall portion 114, Ya alpha ⁺ side the engaging wall portion 131 of the engaged portion 130 alpha ^- side the engagement wall portion 132, etc.) it is difficult to visually compared and the weak portion 100b _1, even if plastic deformation of the whitening and the like to the plate-shaped portion has occurred, since it is difficult to notice, the portion of the plate-like As a clue, unauthorized access to the engaged portion 130 may be attempted.

  In this regard, in this embodiment, the engaged member protection member 160 shown in FIGS. 26 and 27 is attached to the engaged portion 130 as shown in FIG. By protecting, unauthorized access as described above is prevented. FIGS. 26A and 26B are views showing the engaged member protection member 160 as viewed from (a) the front diagonal upper right and (b) the rear diagonal upper left, respectively. FIG. 27 is a six-sided view of the engaged member protection member 160 of FIG. 26 with the surface on the negative side in the z-axis direction in FIG. FIG. 28 is a diagram showing a state in which the engaged portion protection member 160 of FIG. 26 is attached to the engaged portion 130 of FIG.

As shown in FIG. 26, the engaged member protection member 160 according to this embodiment includes a back surface protection unit 161, a side surface protection unit (a left side surface protection unit 162 and a right side surface protection unit 163), and a flat surface protection unit 164. It is the metal member provided with. As shown in FIG. 28, the back surface protection portion 161 is a surface on the back side in the pushing direction (a surface facing the positive side in the z-axis direction among the outer surfaces of the engaged portion 130; hereinafter referred to as “back surface of the engaged portion”). .) Is a plate-like part. Side protection section 162 and 163, among the outer surfaces of the engaged portion 130, substantially perpendicular to the fragile portion 100B _1, and substantially a plane parallel to the pushing direction of the engaging portion 130 (x-axis positive direction side or x A surface facing the negative side in the axial direction (hereinafter referred to as “side surface of the engaged portion”) is a plate-like portion. Flat protection unit 164, among the outer surfaces of the engaged portion 130, the surface is a surface which is provided integrally with the fragile portion 100b ₁ facing the opposite side surface (y-axis positive direction side. Hereinafter, "engaged portion It is a plate-like part that covers the flat surface of.

By protecting the engaged portion 130 in the engaged portion protection member 160, against the engaged portion 130, fraud from a direction perpendicular to the normal direction (inspector's line of sight direction) of the fragile portion 100b ₁ Access can be prevented. Further, as will be described later, the engaged member protection member 160 is fixed to the engaged portion 130 or the fragile portion 100b ₁ or the like. When an attempt is made to make a hole in the protective member 160, the external force applied from the tool to the engaged member protective member 160 is weak from the engaged member protective member 160 via the engaged member 130. It can be applied indirectly to the portion 100b ₁ or directly from the engaged member protection member 160 to the fragile portion 100b ₁ , and can cause plastic deformation such as whitening in the fragile portion 100b _1. become. That is, even when the unauthorized access from a direction perpendicular to the normal direction of the fragile portion 100b ₁ was made, leaving its mark on the fragile portion 100b _1, it is possible to easily discover the existence of the unauthorized access. In other words, making it easier for the inspector to find the trace of unauthorized access by leaving the trace of unauthorized access to the part that is difficult for the inspector to see, in the part that is easy for the inspector to see. Can do.

The back protection part 161, the left side protection part 162, the right side protection part 163, and the plane protection part 164 cover only a part of the back, left side, right side, and plane of the engaged part 130, respectively. Also good. However, in the engaged member protection member 160 according to the present embodiment, the back surface of the engaged portion 140, the back surface protection portion 161, the left side surface protection portion 162, the right side surface protection portion 163, and the flat surface protection portion 164, respectively. The left side surface, the right side surface, and substantially the entire plane are covered. Moreover, the back surface protection unit 161, the left side surface protection unit 162, the right side surface protection unit 163, and the plane protection unit 164 may be formed by connecting separate members. However, the engaged member protection member 160 of the present embodiment is formed by bending a single metal plate (one flat metal plate cut into a predetermined shape). It has become. As a result, the engaged member protection member 160 not only has an excellent strength that is difficult to be damaged, but also the protection members 161, 162, 163, and 164 that constitute the engaged member protection member 160. out even when an external force is applied to any of the protective part may be the external force so transmitted to the fragile portion 100b _1.

  In addition, in the engaged member protection member 160 of this embodiment, as shown in FIG. 26, the left side protection part 162 and the right side protection part 163 are provided with fitting pieces 160a. As shown in FIG. 28, the fitting piece 160 a is a fitting piece receiving portion provided in the engaged portion 130 when the engaged portion protection member 160 is attached to the engaged portion 130. It fits in 130b. Thus, the engaged portion protection member 160 can be positioned with respect to the engaged portion 130. Although the direction in which the fitting piece 160a is provided is not particularly limited, in this embodiment, the metal plate forming the left side protection part 162 and the right side protection part 163 is disposed on the inner surface side of the engaged part protection member 160. The fitting piece 160a is formed by cutting and raising. For this reason, the fitting piece 160a is elastically displaceable with respect to the left side protection part 162 and the right side surface protection part 163. Therefore, in a state where the fitting piece 160a is fitted in the fitting piece receiving portion 130b, the state where the fitting piece 150a is in close contact with the engaged portion 130 can be maintained. Therefore, not only can the engaged member protection member 160 be prevented from rattling, but also the external force applied to the engaged member protection member 160 can be reliably transmitted to the engaged member 130. ing.

Furthermore, in the engaged portion protection member 160 of the present embodiment, the fitting piece 160a is, as shown in FIG. 28, the front side in the mounting direction of the engaged portion protection member 160 with respect to the engaged portion 130 (y (Axially positive side) is provided so as to be inclined so as to protrude largely toward the inner surface side of the side surface protection parts 162 and 163. For this reason, as shown in FIG. 28A, when the engaged portion protection member 160 is attached to the engaged portion 130, the engaged portion protection is not caused without causing a large resistance. The member 160 can be pushed to a target position. Therefore, at the time of mounting of the engaged portion protection member 160, a force pushing the engaged portion protection member 160 is hardly transmitted to the fragile portion 100b _1, weak portion during attachment of the engaged portion protection member 160 It is possible to prevent 100b ₁ whitening and the like.

On the other hand, as shown in FIG. 28B, when trying to pull out the engaged portion protection member 160 attached to the engaged portion 130 to the front side in the mounting direction (positive side in the y-axis direction). The end of the fitting piece 160a on the front side in the mounting direction (y axis direction positive side) is locked to the fitting piece receiving portion 130b. In other words, the engaged-portion protection member 160 is difficult to remove from the engaged portion 130. Further, when an attempt forcibly pull out the engagement portion protection member 160 from the engaged portion 130, the pullout force is easily transmitted to the fragile portion 100b ₁ through the engaged portion 130, fragile portion 100b ₁ tends to cause plastic deformation such as whitening.

  Furthermore, in the engaged portion protection member 160 of the present embodiment, as shown in FIG. 27, an upright portion 160 b is provided at the front edge of the planar protection portion 164. As shown in FIG. 28 (b), the upright portion 160 b is in front of the connecting wall portion 133 of the engaged portion 130 in the pushing direction when the engaged portion protection member 160 is attached to the engaged portion 130. This is a portion that comes into contact with the side (z-axis direction negative side) surface. As a result, the engaged member protection member 160 attached to the engaged portion 130 is not only in the mounting direction (y-axis direction) of the engaged member protection member 160 but also in the engagement portion 170. It is possible to prevent rattling in the pushing direction (z-axis direction).

Meanwhile, the board case 100 for a game machine of the present embodiment, fragile portion 100b ₁ of the cover member 110, about which are "illegal cancellation whitened portion" described above. As described later, the base end portion 100b ₂ of the rod-like protrusions of the engaging portion 170 (FIG. 33) also, stress is likely to concentrate, since the plastic deformation of the whitening and the like is likely to occur, as "bad cancellation whitened portion" We are using. In order to make the plastic deformation such as whitening conspicuous, these whitening portions at the time of unauthorized release are usually formed of a transparent thermoplastic resin like the cover member 110 and the base member 120. However, even when whitening occurs in these whitening portions at the time of fraudulent cancellation, the trace of fraudulent opening may be erased by heating the whitened portion with a dryer or the like to make it transparent. In this regard, in the gaming machine substrate case 100 or the like of the present embodiment, by providing a thermal reaction part that changes appearance by heating in the whitening part at the time of unauthorized release, the presence or absence of the act of erasing the trace of unauthorized opening as described above Can be determined from the appearance of the thermal reaction section. Specifically, as shown in FIG. 22, the thermal reaction part 100c is provided in the fragile part 100b ₁ (the whitening part 100b when fraud is released), and the base end of the rod-shaped protrusion of the engaging part 170 is shown in FIG. The thermal reaction part 100c is also provided in the part 100b ₂ (the whitening part 100b when fraud is released).

The heat reaction part 100c will not be specifically limited if the appearance changes in quality by heating.
As an aspect of the appearance change of the thermal reaction part 100c,
(1) The thermal reaction part 100c that was visible or easy to see before heating becomes invisible or difficult to see after heating.
(2) The thermal reaction part 100c that was visible in one aspect before heating becomes visible in another aspect after heating (for example, the color of the thermal reaction part 100c changes before and after heating).
Etc. are exemplified.
In the following, the thermal reaction part that changes in appearance in the above-mentioned aspect (1) may be referred to as a “heat-erasable thermal reaction part”, and the thermal reaction part that changes in appearance in the above-mentioned aspect (2) is referred to as “ It may be referred to as a “heat-mutated thermal reaction part”. The thermal reaction part 100c of this embodiment is of a heat erasure type.

  The thermal reaction unit 100c may be provided in a simple dot shape, a simple line shape, or a simple plane shape. However, if the thermal reaction unit 100c is provided in a pattern formed of characters, figures, symbols, or a combination thereof, the thermal reaction unit 100c is provided. Can be easily identified. As shown in FIGS. 22 and 33, the thermal reaction unit 100c of this embodiment is a graphic representation of a character string consisting of alphabets (a character string “ABC”).

Further, heat-reactive part 100c is provided in the illegal cancellation whitened portion 100b separate member separable from the (fragile portion 100b ₁ or bar projection of the base end portion 100b ₂ of the engaging portion 170) surface (e.g., seals, etc.) It may be a thing.
However, in this case, after canceling fraud,
(1) A separate member provided with the thermal reaction part 100c is cleanly separated from the whitening part 100b at the time of unauthorized release.
(2) The portion that has been whitened at the time of fraud release in the whitening portion 100b at the time of fraud release is heated (at this time, another member provided with the thermal reaction portion 100c is not heated), and the whitening trace at that portion is erased.
(3) The other member provided with the thermal reaction part 100c is fixed to the original place in the whitening part 100b at the time of unauthorized release.
When the whitening trace is erased by the procedure, the heating history does not remain in the thermal reaction unit 100c.

  For this reason, it is preferable that the thermal reaction unit 100c be provided in a state where it cannot be separated from the surface of the whitening portion 100b at the time of fraud release (formed integrally with the surface of the whitening portion 100b at the time of fraud release). As a result, it becomes possible to prevent the whitening mark from being erased by the procedures (1) to (3). The thermal reaction part 100c of this embodiment is also formed integrally with the surface of the whitening part 100b at the time of fraud cancellation.

A method of integrally forming the thermal reaction part 100c with the whitening part 100b at the time of fraud release is also not particularly limited.
As a method of integrally forming the thermal reaction portion 100c with respect to the whitening portion 100b at the time of fraud release,
(1) Method of forming a concave or convex portion on the surface of the whitening portion 100b at the time of fraud cancellation (the concave portion or convex portion can be formed by, for example, engraving, fogging or embossing) (2) by heating Examples include a method of applying paint or the like whose appearance changes to the surface of the whitening portion 100b at the time of unauthorized release (3) a method of mixing a pigment or the like that changes in quality with heating into the molding material of the whitening portion 100b at the time of unauthorized release.

FIG. 29 is a view of a portion where the thermal reaction portion 100c in the whitening portion 100b at the time of fraud cancellation is cut by a plane perpendicular to the surface (front surface) of the whitening portion 100b at the time of fraud cancellation and viewed from an oblique direction. Heat-reactive part 100c of the present embodiment, as shown in FIG. 29, a one formed by fine engraving numerous fine convex portions 100c ₁ and fine recesses 100c ₂ on the surface of the fraudulent cancellation whitened portion 100b ing.

Heating the heat-reactive part 100c consisting of fine protrusions 100c ₁ and fine recesses 100c _2, why the thermal reaction unit 100c is or less visible invisible, is presumed to be as follows. That is, the heat-reactive part 100c consisting of fine protrusions 100c ₁ etc., before the heating is in a state of standing sharp edges, such as the fine convex portion 100c _1, visually easily (shadow such fine convex portions 100c ₁ Or the projections 100c _{1 and the} like become prisms, and the light emitted from each of the fine projections 100c ₁ is dispersed, and a rainbow-colored portion appears.) When heated, however, the fine projections 100c ₁ Are melted and the edges of the fine convex portions 100c _{1 and the} like are rounded, and the surface of the thermal reaction portion 100c becomes smoother (smoothed) than before heating, so that it is difficult to see (the fine convex portions 100c ₁ may become shadows obscuring the like, the emitted light is not spectrally from each fine convex portion 100c _1, the portion visible iridescent or hardly appear) is presumed for.

In the thermal reaction unit 100c of the present embodiment, the fine convex portions 100c ₁ and fine recesses 100c ₂ is formed in a linear shape, adjacent fine protrusions 100c ₁ and the fine convex portions 100c _2, and the fine adjacent recess 100c ₂ and fine recess 100c ₂ are arranged in parallel with a predetermined interval. Thus regularly the arrayed linear fine protrusions 100c ₁ and fine recesses 100c ₂ can be easily formed by the above finely engraved like. The thus regularly arranged linear thermal reaction unit 100c consisting of fine protrusions 100c ₁ and fine recesses 100c ₂ is greater change in appearance before and after heating. The reason is that, in the heat reaction part 100c before heating, the shadow of the fine convex part 100c _{1 and the} like is easily seen, and the prism action in the fine convex part 100c _{1 and the} like is more likely to appear. Presumed to be.

(In the heat-reactive part 100c of the present embodiment corresponds to the depth of the fine recesses 100c _2.) The height _{H 1} (FIG. 29) of the fine protrusion 100c ₁ is not particularly limited. However, if the fine convex part 100c ₁ is made too high (the fine concave part 100c ₂ is made too deep), even if the thermal reaction part 100c is heated, the thermal reaction part 100c becomes difficult to smooth as described above, and before and after heating. There is a possibility that the change in the appearance of the thermal reaction unit 100c is reduced. Therefore, the height _{H 1} of the fine protrusion 100c ₁ is usually a 300μm or less. The height H ₁ of the fine convex part 100c ₁ is preferably 100 μm or less, more preferably 50 μm or less, further preferably 10 μm or less, and most preferably 5 μm or less. The height limit of an H ₁ of the fine protrusion 100c ₁ is not particularly limited, preferred considering the molding easiness and processability, etc. of the fine protrusion 100c _1, when the set more than 0.1 [mu] m. In the thermal reaction unit 100c of the present embodiment, the height _{H 1} of the fine protrusion 100c ₁ has a 1 [mu] m.

(In the heat-reactive part 100c of the present embodiment corresponds to the arrangement pitch of the fine recesses 100c _2.) Fine arrangement pitch _{P 1} of the convex portion 100c ₁ (FIG. 29) is also not particularly limited. However, an excessively wide arrangement pitch P ₁ of the fine protrusion 100c _1, there is a possibility that the arrangement density of the fine protrusion 100c ₁ becomes too coarse, it is difficult to visually heat-reactive part 100c before heating. Therefore, the arrangement pitch _{P 1} of the fine protrusion 100c ₁ is usually a 300μm or less. The arrangement pitch P ₁ of the fine protrusions 100c ₁ is preferably 100 μm or less, more preferably 50 μm or less, further preferably 10 μm or less, and most preferably 5 μm or less. The lower limit of the arrangement pitch P ₁ of the fine protrusion 100c ₁ is not particularly limited, preferred considering the molding easiness and processability, etc. of the fine protrusion 100c _1, when the set more than 0.1 [mu] m. In the thermal reaction unit 100c of the present embodiment, the height _{P 1} of the fine protrusion 100c ₁ has a 2 [mu] m.

Further, in the gaming machine substrate case 100 of the present embodiment, as shown in FIG. 22, the comparison portion 100 d is provided at a location different from the location where the thermal reaction portion 100 c is provided on the cover member 110. The comparison portion 100d is formed by performing the same processing as the thermal reaction portion 100c on a portion formed of the same material (the same thermoplastic resin) as the portion forming the thermal reaction portion 100c in the cover member 110. Yes. That is, if the thermal reaction part 100c is formed by fine engraving, the comparison part 100d is also formed by the same fine engraving. Etc. The height _{H 1} of the fine protrusion 100c ₁ (FIG. 29) and the arrangement pitch _{P 1} of the fine protrusion 100c ₁ (FIG. 29) is also set the same in a comparison unit 100d and the heat-reactive part 100c. The pattern for providing the comparison unit 100d is not necessarily matched with the pattern for providing the thermal reaction unit 100c, but the comparison unit 100d of this embodiment uses the character string “ABC” in the same manner as the thermal reaction unit 100c. It is represented by a graphic pattern. For this reason, the comparison part 100d before heating has almost the same appearance as the thermal reaction part 100c before heating.

  Thus, by providing the comparison part 100d in a place different from the place where the thermal reaction part 100c is provided, by comparing the thermal reaction part 100c with the comparison part 100d, the change that has occurred in the thermal reaction part 100c It becomes easy to notice. That is, it becomes possible to easily determine whether or not the thermal reaction unit 100c is heated. Therefore, even when the whitening mark generated in the whitening portion 100b at the time of fraud release is heated and erased at the time of fraud release, it is possible to find out.

The place where the comparison part 100d is provided is not particularly limited as long as it is a part formed of the same material as the thermal reaction part 100c in the gaming machine member such as the cover member 110 and the base member 120. In the example of FIG. 22, a thermal reaction unit 100c provided in the fragile portion 100b _1, and a comparison unit 100d for comparing this heat-reactive part 100c, both are provided on the same member (the cover member 110), but The comparison unit 100d may be provided on a member (for example, the base member 120, the protective cover 300, or the like) different from the member provided with the thermal reaction unit 100c to be compared with the comparison unit 100d.

  However, if the comparison unit 100d is too close to the thermal reaction unit 100c, the thermal reaction unit 100b may be heated when the whitening unit 100b for unauthorized cancellation is heated for the purpose of erasing the trace of whitening that has occurred in the whitening unit 100b for unauthorized cancellation. The heat applied to 100c is easily applied to the comparison unit 100d in the same manner, and the comparison unit 100d is easily altered in the same manner as the thermal reaction unit 100c. For this reason, by comparing the thermal reaction part 100c and the comparison part 100d, it becomes difficult to notice the alteration that has occurred in the thermal reaction part 100c. Therefore, it is preferable that the comparison unit 100d is disposed at a location some distance from the thermal reaction unit 100c. Specifically, the comparison part 100d is preferably provided at a position 5 mm or more away from the thermal reaction part 100c, and more preferably provided at a position 10 mm or more away.

  On the other hand, if the comparison unit 100d is too far from the thermal reaction unit 100c, it is difficult to compare the comparison unit 100d with the thermal reaction unit 100c. For this reason, it is preferable to arrange the comparison unit 100d at a location somewhat close to the thermal reaction unit 100c. Specifically, the comparison unit 100d is preferably provided within a radius of 200 mm from the thermal reaction unit 100d, and more preferably provided within a radius of 100 mm from the thermal reaction unit 100d.

Although not adopted in the gaming machine substrate case 100 of the present embodiment, an identification display unit provided with a display made up of characters, figures, symbols, colors, or combinations thereof is superimposed on the thermal reaction unit 100c. It can also be provided. In other words, it is preferable that the identification display portion is disposed in a place on the back side (back side) of the thermal reaction unit 100c as viewed from the person who confirms the heating history of the thermal reaction unit 100c. Thereby, it is possible to further easily identify the appearance change before and after heating of the thermal reaction unit 100c. For example, in the case where the thermal reaction unit 100c is the above-described heating erasure type and the above-described identification display unit is provided, the identification that was covered or not visible by the thermal reaction unit 100c before heating is performed. After the heating of the display unit, the thermal reaction unit 100c can be made inconspicuous (transparent or the like) or can be easily seen.

The partition walls 126 and 127 are not only used as partitions, but also as guides when the cover member 110 is slid vertically with respect to the base member 120 in the assembly procedure 2 and the resealing procedure 2 described above. It has become a functional part.

  As shown in FIG. 31, on the front side of the rear wall 121 of the base member 120, the “A caulking part”, the “B caulking part”, the “C caulking part” and the “F caulking part” are formed. Are each provided with an engaging portion 170. The two engaging portions 170 provided in the “A caulking portion” of the base member 120 are used as the “A caulking portion” of the cover member 120 when the cover member 110 is assembled to the base member 120. It is a part for pushing and engaging with the provided engaged portion 130 (FIG. 23). Further, the engaging portion 170 provided in the “B crimping portion” and the “C crimping portion” of the base member 120 is a “B crimping” for assembling the base member 120 (the board case 100 for the gaming machine) to the case holder 200. And in the case of “C caulking”, it is a part for pushing and engaging with the engaged movable body 220 (FIG. 15) provided in the case holder 200.

  Furthermore, the engaging portion 170 provided in the “F crimping portion” of the base member 120 is engaged when the cover member 110 and the base member 120 are “F crimped” in the return procedure 3 described above. It is a part for pushing and engaging with (FIG. 31). In the gaming machine substrate case 100 of the present embodiment, as shown in FIG. 31, initially (at the time of factory shipment), the engaged portion 180 is integrally formed at the lower right corner of the base member 120. It has become. As described in the return procedure 3 above, the engaged portion 180 is separated from the base member 120 when performing “F-caulking”, and the separated engaged portion 180 is removed from the cover member 110. By engaging the engaged portion insertion port 110b (FIG. 7A) provided at the right end portion of the upper wall portion 114 from above, the “F crimping portion” of the base member 120 The engaging portion 170 is in an engageable state. The engaged portion 180 is in a state of being connected only to a portion around the engaged portion 180 in the base member 120 through an easily breakable portion such as a fine rib when shipped from the factory. It can be easily separated.

  In the base member 120, an engaging portion 170 constituting an “A caulking portion”, an engaging portion 170 constituting a “B caulking portion”, an engaging portion 170 constituting a “C caulking portion”, and an “F caulking portion” The engaging portion 170 constituting the “part” may have different specifications such as dimensions and shapes. However, in this case, the number of parts having different specifications may increase, and the fixing operation of the engaging portion 170 with respect to the base member 120 may be complicated.

  For this reason, in the base member 120 of this embodiment, all the engaging portions 170 shown in FIGS. 33 and 34 are used, and the specifications of these engaging portions 170 are the same. In addition, as shown in FIG. 31, the pushing direction (z-axis direction) in the “A crimping portion” and the “F crimping portion”, and the pushing direction (x-axis direction) in the “B crimping portion” and the “C crimping portion”. However, in any “crimping portion”, the fixing surface 171a (FIG. 33) of the engaging portion 170 is fixed to the base member 120 from the front. Therefore, it is possible to reduce manufacturing costs and the like.

In the following, for convenience of explanation, the specific configuration of the engaging portion 170 will be described by taking as an example the case where the engaging portion 170 is used as an “A crimping portion”, and the engaging portion 170 will be referred to as a “B crimping portion”. A description of the case of using as a “C-caulking part” or the like is omitted. In the base member 120 of the present embodiment, the engaging portions 170 such as “B caulking portion” and “C caulking portion” have the same form as the engaging portion 170 of “A caulking portion”. The contents described regarding the engaging portion 170 of the “crimped portion” also apply to the other engaging portions 170. However, as already mentioned, "A caulking portion", than the "B caulking portion" and "C caulking portion", since the different locations to provide the fragile portion 100b _1, "B caulking contents stated below When applying to the “part” and “C crimping part”, it is necessary to reverse the “β ⁺ side” and the “β ^- side”.

The form of the engaging portion 170 is not particularly limited as long as it can be engaged with the engaged portion 130. As shown in FIG. 33, the engaging portion 170 of this embodiment includes a fixed base 171 for fixing to the base member 120, and an α ⁺ β ⁺ side engagement provided so as to protrude from the fixed base 171 toward the back in the pressing direction. The joint portion 172, the α ⁺ β ⁻ side engagement portion 173, the α ⁻ β ⁺ side engagement portion 174, and the α ⁻ β ⁻ side engagement portion 175 are configured. The α ⁺ β ⁺ side engaging portion 171 is located on the α ⁺ side and the β ⁺ side, the α ⁺ β ⁻ side engaging portion 172 is located on the α ⁺ side and the β ⁻ side, and α ⁻ The β ⁺ side engagement portion 173 is located on the α ⁻ side and the β ⁺ side, and the α ⁻ β ⁻ side engagement portion 174 is located on the α ⁻ side and the β ⁻ side.

The α ⁺ β ⁺ side engaging portion 172, the α ⁺ β ⁻ side engaging portion 173, the α ⁻ β ⁺ side engaging portion 174, and the α ⁻ β ⁻ side engaging portion 175 are all pushed in by the engaging portion 170. It consists of rod-shaped protrusions arranged substantially parallel to the direction (z-axis direction), and an engagement portion (hook portion) for engaging with the engaged portion 130 is formed on the tip side thereof. Yes. alpha ⁺ side alpha ⁺ beta ⁺ side engaging portion 172 and alpha ⁺ beta ^- side engaging portion 173 (. In the following, the which may be referred to as "alpha ⁺ side engaging portion 172, 173") the hook portion of the Is provided in a state of projecting to the α ⁺ side so as to be able to engage with the α ⁺ side engaged wall portion 131 of the engaged portion 130 (FIG. 24), and the α ⁻ side α ⁻ β ⁺ side engagement. The hook portions of the joint portion 174 and the α ^- β ^- side engaging portion 175 (hereinafter, sometimes referred to as “α ^- side engaging portions 174, 175”) are engaged portions 130 (FIG. 24). ) To be engaged with the α ^- side engaged wall portion 132 in a state protruding from the α ^- side.

a pushing direction inner side surface of the hook portion of the alpha ⁺ side engaging portion 172, 173, alpha ^- as The pushing direction inner side surface of the hook portion of the side engaging portions 174, 175, the pushing direction inner side It is formed in an inclined state so as to approach each other. For this reason, when the engaging portion 170 is pushed into the engaged portion 130, the surface on the far side in the pushing direction of the hook portions of the α ⁺ side engaging portions 172 and 173 is located on the engaged portion 130 (FIG. 24). alpha ⁺ by abutting the pushing direction front side of the surface on the engaging wall portion 131, the hook portion of the alpha ⁺ side engaging portion 172 and 173 alpha ^- and the side elastic displacement, alpha ^- side engaging portion by abutting the pushing direction front side of the surface on the engaging wall portion 132, alpha ^{- -} pushing direction inner side surface of the hook portion of the 174 and 175, alpha engaged portion 130 (FIG. 24) side The hook portions of the engaging portions 174 and 175 are elastically displaced toward the α ⁺ side. That is, when the engaging portion 170 is pushed into the engaged portion 170 and engaged with each other, as shown by hatching in FIG. 35, the α ⁺ side engaging portions 172 and 173 and the α ⁻ side engaging portion 174 and 175 are elastically displaced toward each other in the α direction.

Further, as already described, the engaging portion abutting surface 140a of the pushing displacement restricting portion 140 and the engaging portion abutting surface 150a of the proximity displacement restricting portion 150 come closer to each other toward the back in the pushing direction. It is inclined to. For this reason, when the engaging portion 170 is pushed into the engaged portion 130, the β ⁺ side α ⁺ β ⁺ side engaging portion 172 and the α ⁻ β ⁺ side engaging portion 174 (hereinafter referred to as “β ⁺ Side engagement portions 172 and 174 ”), and β ⁻ side α ⁺ β ⁻ side engagement portion 173 and α ⁻ β ⁻ side engagement portion 175 (hereinafter referred to as“ β ⁻ side ”). The engagement portions 173 and 175 "may be expressed as the broken lines in FIG. 35 so as to be elastically displaced toward each other in the β direction.

Thus, the engaging part 170 of this embodiment is elastically displaced in both the α direction and the β direction when the engagement is performed. For this reason, when the engagement by the engagement portion 170 is illegally released, the α ⁺ side engagement portions 172 and 173 and the α ⁻ side engagement portions 172 and 173 are moved toward each other in the α direction. A very difficult task of pulling out the engaging portion 170 while displacing the β ⁺ side engaging portions 172 and 174 and the β ⁻ side engaging portions 173 and 175 in a direction approaching each other in the β direction. Is required. In addition, in this embodiment, when the engaging portion 170 is engaged with the engaged portion 130, the pushing displacement restricting portion 140 (FIG. 24) is inserted into the gap between the β ⁺ side engaging portions 172 and 174. Since the proximity displacement restricting portion 150 (FIG. 24) is positioned in the gap between the β ^- side engaging portions 173 and 175, the operation is further difficult.

Therefore, it is difficult for the engaging portion 170 to illegally release the engagement without leaving a trace such as whitening. In particular, the base end portion 100b _{2 of} the α ⁺ β ⁺ side engaging portion 172, the α ⁺ β ⁻ side engaging portion 173, the α ⁻ β ⁺ side engaging portion 174, and the α ⁻ β ⁻ side engaging portion 175 (FIG. 33). ) Is a portion where elastic deformation is likely to occur (a portion where stress is likely to concentrate), and is a location that can be easily used as the whitening portion 100b at the time of fraud release. Therefore, the base end portions of the α ⁺ β ⁺ side engaging portion 172, the α ⁺ β ⁻ side engaging portion 173, the α ⁻ β ⁺ side engaging portion 174, and the α ⁻ β ⁻ side engaging portion 175 (at the time of unauthorized release) The whitening portion may be provided with a thermal reaction portion 100c that changes in appearance when heated for the same reason as the provision of the thermal reaction portion 100c in the fragile portion 100b ₁ (FIG. 22).

In this case, all the base end portions 100b _{2 of} the α ⁺ β ⁺ side engaging portion 172, the α ⁺ β ⁻ side engaging portion 173, the α ⁻ β ⁺ side engaging portion 174, and the α ⁻ β ⁻ side engaging portion 175 are used. Although a thermal reaction part may be provided on the board, it is effective to provide it on a part that is easily visible from the front side of the board case 100 for gaming machines. In the engagement portion 170 (engagement portion 170 of the “A crimping portion”) of this embodiment, the α ⁺ β ⁻ side engagement portion 173 and the α ⁻ β ⁻ side engagement portion are provided inside the gaming machine substrate case 100. 175 is positioned in front of the α ⁺ β ⁻ side engaging portion 173 and the α ⁻ β ⁻ side engaging portion 175, and is a portion that is easily visible from the front side of the board case 100 for gaming machines. . Therefore, the engaging portion 170 of the present embodiment, as shown in FIG. 33, alpha ⁺ beta ^- the surface facing the front at the proximal end of the side engaging portion 173 is provided with a heat-reactive part 100c. Specific configuration of the heat-reactive part 100c of the engaging portion 170 are the same as that described for the thermal reaction unit 100c in the fragile portion 100b _1, it omitted a detailed description.

However, when providing the thermal reaction part 100c in the engaging part 170, the following structures are also employable. FIG. 36 is an oblique view of the engaging portion 170 of another embodiment. In the engagement portion 170 of FIG. 33, all of the α ⁺ β ⁺ side engagement portion 172, the α ⁺ β ⁻ side engagement portion 173, the α ⁻ β ⁺ side engagement portion 174, and the α ⁻ β ⁻ side engagement portion 175 are all included. However, in the engaging portion 170 of FIG. 36, the α ⁺ β ⁻ side engaging portion that is easily visible from the front side of the gaming machine substrate case 100 is extended from the base end portion to the tip end portion. 173 and alpha ^- beta ^- and is curved proximal portion 100b ₂ of the side engaging portion 175. Thus, alpha ⁺ beta ^- side engaging portion 173 and the alpha ^- beta ^- the base end portion 100b ₂ of the base end portion 100b ₂ of the side engaging portions 175, in particular it made stress easily concentrated. In other words, the α ⁺ β ⁻ side engaging portion 173 and the base end portion 100b ₂ of the α ⁻ β ⁻ side engaging portion 175 are portions that are particularly susceptible to plastic deformation such as whitening upon unauthorized release (whitening upon unauthorized release). The portion is preferably used as the portion 100b.

Further, in the engaging portion 170 of FIG. 33, the thermal reaction portion 100c is provided only at the base end portion of the α ⁺ β ⁻ side engaging portion 173. In addition, in the engaging part 170 of FIG. 33, the thermal reaction part 100c was provided in the pattern which made the character a figure. In contrast, in the engagement portion 150 of FIG. 36, alpha ⁺ beta ^- side engaging portion 173 and the alpha ^- beta ^- from the proximal end 100b ₂ side engaging portion 175 over the vicinity of the distal end portion, the thermal reaction unit 100c Are continuously provided in a strip shape. Therefore, the engagement portion 170 of FIG. 36, alpha ⁺ beta ^- side engaging portion 173 and the alpha ^- beta ^- proximal end of the side engaging portions 175 100b ₂ like whitening generated in the (illegal cancellation whitened portion 100b) It is further difficult to erase the traces of the above without altering the thermal reaction part 100c.

  A method of providing the engaging portion 170 with respect to the base member 120 is not particularly limited. In the base member 120 of this embodiment, the engaging portion 170 made of a member different from the base member 120 is fixed afterwards to a predetermined location in the base member 120. A method for fixing the engaging portion 170 to the base member 120 is not particularly limited, but in the base member 120 of this embodiment, the fixing surface 171a of the fixing base portion 171 of the engaging portion 170 is vibration welded to the target portion. Thus, the engaging portion 170 is fixed to the base member 120.

By the way, the following devices are also applied to the engaging portion 170 of this embodiment. That is, as already mentioned, in the cover member 110 of the present embodiment, as shown in FIG. 13, a state in which the engaged portion 130 is connected to the main body portion of the cover member 110 through the fragile portion 100b ₁ Therefore, when the engaging portion 170 is illegally pulled out from the engaged portion 130 (when the fraud is released), plastic deformation such as whitening occurs in the fragile portion 100b ₁ (the whitening portion 100c when fraud is released). where are easy, also the engaging portion 170 side, devised to plastic deformation is likely to occur in such as whitening to the fragile portion 100b _1.

Specifically, as shown in FIG. 13, the engagement surface 170a of the β ⁺ side engagement portions 172 and 174 (only the α ⁺ β ⁺ side engagement portion 172 is illustrated in FIG. 13) ^- located in the pushing direction front side than the engagement surface 170a of the (z-axis direction negative side) ^- (only side engaging portion 173 is depicted in the figure alpha ⁺ beta.) side engaging portion 173 and 175 as, beta ⁺ and the engagement surface 170a of the side engaging portions 172, 174, beta ^- are provided with a step _{S 1} between the engagement surface 170a of the side engaging portions 173 and 175. For this reason, when the engaging portion 170 engaged with the engaged portion 130 is illegally pulled out, the β ^- side engaging portions 173 and 175 close to the fragile portion 100b ₁ (the whitening portion 100b when fraud is released). before the engagement surface 170a abuts the engaging surface 130a of the engaged portion 130 of the engagement surface 170a is engaged portion distant beta ⁺ side engaging portion 172 and 174 from the fragile portion 100b ₁ 130 abuts on the engaged surface 130 a of 130.

By adopting the above configuration, when the engaging portion 170 is illegally pulled out from the engaged portion 130 (at the time of unauthorized release), the pressing force applied from the engaging portion 170 to the engaged portion 130 is reduced. The moment generated from the boundary portion between the engaged portion 130 and the fragile portion 100b ₁ (the whitening portion 100b when fraud is released) is increased to further easily cause plastic deformation such as whitening in the fragile portion 100b _1. Is possible. In addition, the engagement strength between the engaging portion 170 and the engaged portion 130 can be increased. Therefore, when the illegal cancellation, it is possible to the traces it tends to remain more vulnerable portions 100b ₁ and its peripheral portion.

The level of the step S ₁ (FIG. 13) between the engagement surfaces of the β ⁺ side engagement portions 172 and 174 and the engagement surfaces of the β ⁻ side engagement portions 173 and 175 is not particularly limited. However, the step S ₁ is too small, there is a possibility that the above effect is hardly exerted. Thus, step _{S 1} is usually a 0.1mm or more. Step _{S 1} is preferable to be 0.3mm or more, and more preferably 0.5mm or more. The step S ₁ has no particular upper limit, but for reasons of design of the engaging portion 170 and the like, the step S ₁ is preferably 5 mm or less, and more preferably 3 mm or less.

Moreover, in the base member 120 of this embodiment, the following devices are also given. That is, as shown in FIG. 17, the weakened portion 100b ₁ is also provided around the “B caulking portion” and the “C caulking portion” in the base member 120, and the engaging portion 170 constituting the “B caulking portion” a fixing surface 171a, and a fixing surface 171a of the engaging portion 170 constituting the "C caulking portion", are fixed to these weak portions 100b _1. In other words, the engaging portion 170 of the "C caulking portion" and the engagement portion 170 of the "B caulking portion" is in a state of being connected to the main body portion of the base member 120 through a fragile portion 100b _1. The fragile portion 100b _1, like the fragile portion 100b ₁ of the "A caulking portion", has become one provided as an illegal cancellation whitened portion 100b.

The thickness and area such weak portion 100b ₁ of the "B caulking portion" and "C caulking portion" are the same as those described for fragile portion 100b ₁ of the "A caulking portion", and a description thereof will not be repeated. Further, although not adopted in the base member 120 of the present embodiment, it is the same as the case where the thermal reaction part 100c (FIG. 22) is provided in the weak part 100b ₁ (whitening part 100b when fraud is released) of the “A crimping part”. For this reason, the fragile part 100b ₁ (whitening part 100b when fraud is canceled) in the “B caulking part” or the “C caulking part” can also be provided with a thermal reaction part that changes its appearance when heated.

FIG. 37 is a view showing the case holder 200 as viewed from (a) the front diagonally upper right and (b) the state viewed from the rear diagonal upper left. FIG. 38 shows the case holder 200 as viewed from the front. FIG. 39 is a diagram showing the case holder 200 as viewed from the rear. FIG. 40 shows (a) a state in which the engaged movable body 220 is in a first position where it can be used as a “B caulking portion”, and (b) an engaged portion around the movable body holding portion 210 in the case holder 200. It is the figure which looked at the state in which the movable body 220 exists in the 2nd position which can be used as a "C crimping part" from the diagonally upper left front. Figure 41, the periphery of the movable holding member 210 in the case holder 200, as viewed from the x-axis direction positive side is cut in _X 1 -X ₁ plane of FIG. 38.

  As shown in FIG. 37, the case holder 200 of the present embodiment includes a rear wall portion 201 having a rectangular shape in front view, a right wall portion 203 provided to protrude from the right edge portion of the rear wall portion 201 to the front side, The rear wall portion 201 includes an upper wall portion 204, a lower wall portion 205, and the like provided so as to protrude forward from the upper edge portion and the lower edge portion of the rear wall portion 201, respectively. The upper wall portion 204 and the lower wall portion 205 not only cover the upper surface and the lower surface of the gaming machine substrate case 100 but also the gaming machine with respect to the case holder 200 in the assembly procedure 3 and the resealing procedure 3 described above. It is also a part that functions as a guide when sliding the substrate case 100 in the left-right direction.

  As shown in FIG. 38, a movable body holding part 210 is provided at a portion constituting the “B caulking part” and the “C caulking part” in the case holder 200. In the present embodiment, the movable body holding part 210 is provided in a state protruding from the vicinity of the center of the right edge on the front surface of the rear wall part 201 to the front side. As shown in FIG. 40, the movable body holding unit 210 moves the engaged movable body 220 between a first position shown in FIG. 4A and a second position shown in FIG. It is a part for holding in a possible state.

  The engaged movable body 220 serves as both the engaged portion of the “B caulking portion” and the engaged portion of the “C caulking portion”. That is, the engaged movable body 220 functions as an engaged portion of the “B caulking portion” when it is in the first position (FIG. 40A) (see FIG. 17), and the second position (FIG. When in b)), it functions as the engaged portion of the “C crimping portion”. For this reason, the engaged portion of the “B crimping portion” and the engaged portion of the “C crimping portion” are reused by one movable movable body 220 to reduce the number of parts of the case holder 200 and manufacture. Costs can be held down.

  As long as the movable body 220 to be engaged can be engaged with the engaging portion 170 provided as the “B caulking portion” and the engaging portion 170 provided as the “C caulking portion” on the base member 120, The form is not limited. In the present embodiment, as described above, the engaging portion 170 of the “A caulking portion”, the engaging portion 170 of the “B caulking portion”, and the engaging portion 170 of the “C caulking portion” have the same form. Therefore, the engaged movable body 220 used as the engaged portion of the “B caulking portion” and the “C caulking portion” is similar to the engaged portion 130 used as the “A caulking portion”. It has a structure.

FIG. 42 is a view of the engaged movable body 220 as viewed from the front oblique upper right. 43 is a six-sided view of the engaged movable body 220 of FIG. 42 with the x-axis direction negative surface in FIG. As shown in FIG. 42, the engaged movable body 220 of this embodiment includes an α ⁺ side engaged wall portion 221 positioned on the α ⁺ side (z-axis direction negative side) and an α ⁻ side (z-axis direction). The α ^- side engaged wall portion 222 located on the positive side) is provided. The α ⁺ side engaged wall portion 221 corresponds to the α ⁺ side engaged wall portion 131 of the engaged portion 130 (FIG. 24), and the α ⁻ side engaged wall portion 222 is the engaged portion 130. This corresponds to the α ^- side engaged wall 132 in FIG. The engaged movable body 220 corresponds to the connecting wall portion 223 corresponding to the connecting wall portion 133 of the engaged portion 130 (FIG. 24) and the bottom wall portion 134 of the engaged portion 130 (FIG. 24). A connecting wall 224 is also provided. Therefore, like the engaged portion 130, the engaged movable body 220 has a front view frame type (see the front view of FIG. 42), and is in a state of increased rigidity.

  In addition, in the engaged portion 130 of the “A caulking portion”, as shown in FIG. 24, a pushing displacement restricting portion 140 is provided on the connecting wall portion 133, and a proximity displacement restricting portion 150 is provided on the bottom wall portion 134. As shown in FIG. 43, the engaged movable body 220 is provided with a proximity displacement restricting portion 230 having the same function as the proximity displacement restricting portion 150 on both the connecting wall portion 223 and the connecting wall portion 224. (The portion having the same function as the indentation displacement restricting portion 140 is not provided in the engaged movable body 220). The configuration described in the proximity displacement regulating unit 150 can also be adopted in the indentation displacement regulating unit 230. For this reason, the detailed description about the proximity displacement control part 230 is omitted.

Furthermore, in the “A caulking portion”, as shown in FIG. 13, the engagement surfaces of β ⁺ side engagement portions 172 and 174 (only the α ⁺ β ⁺ side engagement portion 172 is illustrated in FIG. 13). 170a is, beta ^- (in the figure alpha ⁺ beta. ^{that -} only the side engaging portion 173 are illustrated) side engaging portion 173 and 175 pushing direction front side than the engagement surface 170a of the (z-axis direction negative side so as to be positioned), the engagement portion 170 engaged with the engaged portion 130 while attempting to pull out from the engaged portion 130, beta close to the fragile portion 100b ₁ ^- side engaging portion 173 and 175 before the engagement surface 170a abuts the engaging surface 130a of the engaged portion 130 of the engagement surface 170a is engaged portion distant beta ⁺ side engaging portion 172 and 174 from the fragile portion 100b ₁ Although it has been devised to contact the engaged surface 130a of 130, "B caulking part" and "C caulking part" However, the same idea is applied. However, in the present embodiment, the "A caulking portion", than the "B caulking portion" and "C caulking portion", reversed the location of the fragile portion 100b _1, and "beta ⁺ side", "beta ^- side ”Is reversed, so that the above-described effect can be obtained in a manner different from that of the“ A caulking portion ”.

That is, in the “A caulking portion”, as shown in FIG. 13, in the engaging portion 170, the side close to the fixed surface 171 a of the fixed base portion 171 (the positive side in the y-axis direction) is the β ⁺ side (the side far from the weak portion) ), and the farther from the fixing surface 171a of the fixed base 171 side (y-axis direction negative side), beta ^- it has been a side (side close to the fragile portion 100b _1). On the other hand, in the “B caulking portion” and the “C caulking portion”, as shown in FIG. 18, the side closer to the fixing surface 171 a of the fixing base portion 171 (the y axis direction positive side) is β ^- side (the side closer to the weak portion), and the side farther from the fixing surface 171a of the fixed base 171 (y-axis direction negative side), a beta ⁺ side (the side away from the fragile portion 100b _1).

Therefore, the engaging portion 170 of the step _{S 1} to the engagement surface 170a in exactly the same manner as the engaging portion 170 is provided showing the engaging portion 170 (FIG. 13 of exactly the same form as the engagement portion 170 shown in FIG. 13 ) In the “B caulking portion” and the “C caulking portion” as they are, the state shown in FIG. 44 is obtained. 44 shows an engagement portion with respect to an engaged portion (an engaged movable body 220 having a flat engaged surface 220a) provided as “B crimping portion” or “C crimping portion” on the case holder 200. FIG. It is the figure which looked at the state which engaged 170 from the lower part. In the engaging portion 170 of FIG. 44, β ⁺ side engaging portions 172 and 174 (in FIG. 44, only the α ⁺ β ⁺ side engaging portion 172 is depicted) and β ⁻ side engaging portions 173 and 175 (same as above). In the figure, only the α ⁺ β ⁻ side engagement portion 173 is drawn.) For the reasons described above, β ⁺ side engagement portions 172 and 174 and β ⁻ side engagement in the engagement portion 170 of FIG. The parts 173 and 175 are reversed.

Therefore, when trying to pull out the engaging portion 170 from the engaged movable body 220 from the state shown in FIG. 44, the β ^- side engaging portion 173 close to the fragile portion 100b ₁ (the whitening portion 100b when fraud is released). 175 engagement surface 170a is, after the contact with the engaging surface 220a of the engaged movable member 220, the engaging surface 170a of the distant beta ⁺ side engaging portion 172 and 174 from the fragile portion 100b ₁ is to be engaged It comes into contact with the engaged surface 220a of the combined movable body 220. Therefore, the above-described effect obtained in the “A caulking part” cannot be obtained in the “B caulking part” and the “C caulking part”.

For this reason, in this embodiment, as shown in FIG. 18, the engagement portion 170 is engaged with the engaged surface 220a of the engaged movable body 220 constituting the “B crimping portion” and the “C crimping portion”. A step S ₂ is provided that exceeds the step S ₁ at the mating surface. As a result, even if a part having the same form as the engaging part 170 of the “A caulking part” is used as the engaging part 170 of the “B caulking part” and the “C caulking part”, the weak part 100b ₁ (at the time of unauthorized release) whitening unit 100b) closer to the beta ^- before the engagement surface 170a of the side engaging portions 173 and 175 abut against the engaging surface 220a of the movable member 220 for the engaged, farther beta ⁺ side from a fragile portion 100b ₁ The engaging surfaces 170a of the engaging portions 172 and 174 come into contact with the engaged surface 220a of the engaged movable body 220. Therefore, in the “B crimping portion” and the “C crimping portion” as well as the “A crimping portion”, when the engagement portion 170 is illegally pulled out from the engaged movable body 220 (at the time of unauthorized release). the moment generated in the vicinity of the boundary portion between the engaging portion 170 and the weak portion 100b ₁ is increased, it is possible to plastic deformation easier to occur such as whitening fragile portion 100b _1.

The step S ₂ (FIG. 18) on the engaged surface 220a of the engaged movable body 220 is not particularly limited as long as it is larger than the step S ₁ (FIG. 13) on the engaging surface 170a of the engaging portion 170. However, if the difference S ₂ −S ₁ between the step S ₂ and the step S ₁ is too small, the above effects may not be achieved. For this reason, the difference S ₂ −S ₁ is normally set to 0.1 mm or more. The difference S ₂ −S ₁ is preferably 0.3 mm or more, and more preferably 0.5 mm or more. The difference _S 2 -S _1, particularly no upper limit, for reasons such as Design of the engaged movable member 220, the difference _S 2 -S ₁ is preferably When 5mm or less, and more preferably to less than 3mm.

Further, in the present embodiment, as shown in FIG. 42, a flange-shaped held portion 225 is provided on the far side in the pressing direction of the engaged movable body 220. As shown in FIG. 41, the held portion 225 is a portion that is held in a state of being fitted in the internal space of the movable body holding portion 210. The width W _{1 in the} direction perpendicular to the sliding direction (z-axis direction) in the held portion 225 is perpendicular to the sliding direction (z-axis direction) in the engaged portion exposing opening 211 a of the movable body holding portion 210. It is wider than the width W _{2 in the} direction.

  For this reason, the engaged movable body 220 held by the movable body holding section 210 is in a state where it cannot be removed from the movable body holding section 210 unless the movable body holding section 210 is destroyed. In other words, the engaged movable body 220 is detached from the other part of the case holder 200 (the main body part of the case holder 200) and is not carried independently from the main body part. Accordingly, it is possible to prevent an illegal act such as replacing the engaged movable body 220 with a counterfeit product that is easily disengaged.

  Further, the engaged movable body 220 is provided with a positioning fitting portion 220b as shown in FIG. The positioning fitting portion 220 b is a portion for positioning the engaged movable body 220 with respect to the movable body holding portion 210. That is, as shown in FIG. 41, the positioning fitting portion 220b is fitted to the first position fitted portion 210b of the movable body holding portion 210 when the engaged movable body 220 is in the first position. When the engaged movable body 220 is in the second position, the movable body holding portion 210 is fitted into the second position fitted portion 210c.

  As a result, when the gaming machine substrate case 100 is assembled to the case holder 200 (when performing “B caulking” or “C caulking”) in the assembling procedure 3 and the resealing procedure 3 described above, The combined movable body 220 can be engaged with the engaging portion 170 (first position engaging portion) of the “B caulking portion” or the engaging portion 170 (second position engaging portion) of the “C caulking portion”. It can be moved to an appropriate position and held at that position. Further, when carrying the case holder 200 to which the board case 100 for gaming machines is not yet assembled, it is possible to prevent the engaged movable body 220 from rattling and being damaged with respect to the movable body holding portion 210. It has become. The place where the positioning fitting portion 220b is provided is not particularly limited, but is provided on the outer peripheral portion of the held portion 225 in this embodiment.

  The movable body holding portion 210 is configured to be able to slide the engaged movable body 220, and the engaged movable body 220 cannot be removed unless the movable body holding portion 210 is destroyed. If 220 can be held, the specific structure is not particularly limited. As such a structure, for example, the movable body holding portion 210 is configured by a holding portion main body and a holding portion closing body made of different members, and the engaged movable body 220 is held by the holding portion main body. Then, a structure is provided in which the holding unit closing body is assembled to the holding unit main body and fixed by adhesion or the like, so that the engaged movable body is pressed by the holding unit closing body so as not to be pulled out from the holding unit main body. be able to.

  However, in this type of structure, the entire boundary line between the holding portion main body and the holding portion closing body is arranged on the front side of the case holder 200 (the engaging portion 170 of the “B crimping portion” or the “C crimping portion” is arranged. A cutting tool such as a cutter is inserted into the boundary line from the front side of the movable body holding section 210, and the movable body holding section 210 is cut cleanly along the boundary line. Then, after disassembling the holding portion main body and the holding portion closing body, removing the engaged movable body 220 and replacing it with a counterfeit, the holding portion main body and the holding portion closing body are bonded together along the boundary line. When cheating is done, there is no noticeable trace and it may be difficult to notice the cheating. For this reason, in this embodiment, the movable body holding part 210 is configured as follows so that the entire boundary line between the holding part main body and the holding part closing body does not appear on the front side of the case holder 200. I am doing so.

  45 (a) shows a movable body holding when the engaged movable body 220 is arranged on the left side of the holding section main body 211, and (b) when the engaged movable body 220 is housed in the holding section main body 211. It is the figure which looked around the part 210 from the front diagonal left. 46A and 46B show the movable part holding body 212 (a) before fitting into the predetermined position of the case holder 200 from the rear side and (b) after fitting into the predetermined position. It is the figure which looked around the part 210 from the front diagonal left. 48A and 48B show the case holder 200 before (a) fitting the holding portion closing body 212 into the predetermined position of the case holder 200 from the rear side, and (b) after fitting into the predetermined position. It is the figure which looked at from back diagonally upper left.

  In this embodiment, as shown in FIG. 45, the movable body holding portion 210 is separated from the holding portion main body 211 provided integrally with the main body portion of the case holder 200 and the main body portion of the case holder 200. It is comprised with the holding | maintenance part obstruction body 212 which consists of a member. The holding portion main body 211 is provided with an engaged portion exposing opening 211a. As shown in FIG. 45B, in the engaged movable body 220 accommodated in the internal space of the holding portion main body 211. The engaged portion is exposed to the outside of the holding portion main body 211 from the engaged portion exposing opening 211a. The holder main body 211 is also provided with a movable body accommodating opening 211 b for accommodating the engaged movable body 220 from the outside of the holder main body 211 in the internal space of the holder main body 211.
