Description

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

  A gaming machine can be subject to various fraudulent acts. For example, a main control board is accommodated inside 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 a fraudulent act of replacing this storage device with a forged one (so-called forged ROM). In order to prevent this type of fraud, each maker of a game machine has a structure in which an electronic board such as a main control board is housed and sealed in a case (board case for game machine). The specific form of the gaming machine substrate case varies depending on the type of the electronic substrate accommodated in the gaming machine and the installation location thereof, etc. A cover member covering the upper surface side of the electronic substrate and a base covering the lower surface side of the electronic substrate It is common to have a member.

  In this type of gaming machine substrate case, the cover member and the base member are normally sealed by engaging the engaging portion provided on one member with the engaged portion provided on the other member. It has a structure. Therefore, in the conventional gaming machine substrate case, when the cover member is removed illegally from the base member, the engaging portion or the engaged portion or the periphery thereof can be easily found. In addition, a device has been applied to ensure that a trace of tampering remains.

  For example, in the past, a fragile portion that is more fragile than the surroundings is provided at and around the engagement portion by the engagement portion and the engagement portion, and the engagement between the engagement portion and the engagement portion is incorrect. There has also been proposed a gaming machine substrate case in which plastic deformation such as whitening or breakage is caused in the fragile portion when it is attempted to be released (illegal opening) (see, for example, connection in FIG. 10 of Patent Document 1). See section 15a and paragraph 0067 etc.). In this type of gaming machine substrate case, it is possible to determine whether or not the engagement has been illegally released by confirming the presence or absence of plastic deformation in the fragile portion.

JP 2005-144015 A

  However, in the gaming machine substrate case provided with a portion (whitening portion at the time of tampering release) intended to cause plastic deformation such as whitening at the time of tampering as in the above-described fragile portion, tampering In this case, even if whitening occurs in the whitening part at the time of fraud release, there is a possibility that traces of fraud release may be erased by heating the whitened part with a dryer or the like to make it transparent. The inventor of the present application has come to mind.

  The present invention has been made to solve the above-described problems, and even if whitening that has occurred in the whitening portion at the time of tampering removal during unauthorized opening has been erased by heating with a dryer or the like, the whitening may occur. By providing a history, and making it possible to discover the fact of tampering, it is possible to provide a gaming machine member such as a gaming machine substrate case and the like, which is enhanced in the tampering prevention effect. Another object of the present invention is to provide a gaming machine provided with this gaming machine member.

The above task is
A gaming machine member constructed by assembling an engaging portion provided in a first member and an engaged portion provided in a second member,
At least one of the first member and the second member is formed of a thermoplastic resin, and a part of the member formed of the thermoplastic resin engages the engagement between the engaging portion and the engaged portion. There is provided a whitening part at the time of fraud release that can be whitened when fraudulently released,
In the whitening part at the time of fraud release, a thermal reaction part whose appearance is altered by heating is provided ,
It is an object of the present invention to provide a gaming machine member characterized in that the heat reaction portion comprises a convex portion or a concave portion formed in the whitening portion at the time of fraud release in a state where it can not be separated from the surface of the whitening portion at the time of fraud release. Resolved by

  By adopting this configuration, it is possible to confirm the heating history of the whitening part at the time of fraud release by visually observing the state of the heat reaction part. Therefore, when the engagement between the engaging portion and the engaged portion in the first member or the second member is improperly released, the portion (whitening portion at the time of fraud release) which is whitened or the like is heated by a dryer or the like, Even if the whitening mark is erased, the heat reaction part will have a history of heating, which makes it possible to detect unauthorized access.

Also , if the heat reaction part is provided on another member (for example, a seal that can be attached to the first member or the second member) that can be separated from the first member or the second member,
(1) The separate member provided with the heat reaction part is finely separated from the first member or the second member.
(2) The whitened part in the first member or the second member is heated (at this time, the separate member provided with the heat reaction part is not heated), and the whitening mark of the part is erased.
(3) The separate member provided with the heat reaction part is fixed to the original place in the first member or the second member.
When the removal of the whitening mark is performed according to the above procedure, the heating history does not remain in the heat reaction part.
In this respect, by adopting the above configuration in which the thermal reaction portion is formed directly (integrally) with respect to the surface of the first member or the second member, the portion provided with the thermal reaction portion can be a first member And since it becomes impossible to separate from a 2nd member, it becomes possible to make it impossible to perform trace concealment by the procedure of said (1)-(3).
Further, the number of parts constituting the first member and the second member can be reduced.

  In the gaming machine member of the present invention, when the heat reaction unit is provided in a state where it can not be separated from the whitening unit at the time of fraud release, the heat reaction unit is a large number of fines formed on the surface of the whitening unit at the time of fraud release. It is preferable to be composed of a convex portion or a minute concave portion.

By adopting such a configuration, the heating and erasing (integrated in the first member or the second member) in an inseparable state from the first member or the second member with respect to the surface of the first member or the surface of the second member It becomes possible to easily form the thermal reaction part of the mold. The reason why the heat reaction part consisting of a large number of fine convex parts or fine concave parts becomes invisible or hard to see if it is heated (If the heat reaction part is composed of a large number of fine convex parts or fine concave parts, it becomes a thermal reaction part of heating erase type The reason is assumed to be as follows.
That is, before heating, the heat-responsive portion consisting of fine convex portions and the like is in a state where the edges of the convex portions and the like are sharp and easy to view (the shadow of the convex portions can be seen, and each convex portion And the light emitted from each convex part is dispersed and parts appear to be iridescent), but when heated, the convex parts etc. melt and the edges of the convex parts become round and the surface of the heat reaction part Becomes smoother than before heating (smoothing), making it difficult to see (the shadows of the projections are difficult to see or the light emitted from each It is guessed that it becomes difficult to appear.

  In the gaming machine member according to the present invention, in the case where the heat reaction portion is constituted by a large number of fine projections or fine recesses, the heat reaction portion is a large number of linear fine projections arranged at predetermined intervals. It is preferable to be composed of a part or a linear fine recess.

  By adopting such a configuration, it becomes possible not only to more easily process the heat reaction portion consisting of a large number of fine convex portions or fine concave portions, but also to easily exhibit the above-mentioned prism action.

  Further, in the gaming machine member according to the present invention, the engaging portion is formed of a rod-like protrusion having an engaging portion engaged with the engaged portion on the distal end side, and the base end of the rod-like protrusion It is preferable to provide the heat reaction part in the whitening part at the time of fraud release as the part is a whitening part at the time of fraud release.

  When trying to remove an engaging part consisting of a rod-like protrusion having an engaging part on the distal end side from the engaged part, it is usually necessary to bend and deform the proximal end side (proximal side of the rod-like protrusion) of the engaging part There is a possibility that whitening occurs on the proximal end side of the rod-like protrusion, but by adopting this configuration, it is difficult to eliminate whitening occurring in this part (erasure in a state where the heat reaction part is not degraded). Can.

Furthermore, in the gaming machine member according to the present invention, the engaging portion is connected to the other portion of the first member via the fragile portion formed to be more fragile than the other portions of the first member, It is also preferable to provide the heat reaction part in the whitening part at the time of fraud release with the fragile part as the whitening part at the time of fraud release. Similarly, the engaged portion is connected to the other portion of the second member via the fragile portion which is formed more fragile than the other portion of the second member, and the heat is removed from the whitening portion when the fraud is released. It is also preferable to provide a reaction part.

  When the engaging portion and the engaged portion are provided to the first member and the second member via the fragile portion as in this configuration, the engagement between the engaging portion and the engaged portion may be removed. In this case, it is considered that whitening is likely to occur particularly in the fragile part. By providing the thermal reaction part in the fragile part as in this configuration, the whitening elimination in the fragile part is eliminated (the thermal reaction part is degraded Can be made difficult).

  Furthermore, in the gaming machine member according to the present invention, the portion other than the portion provided with the heat reaction portion in the first member or the second member, or the third member made of thermoplastic resin assembled to these members. It is also preferable to provide a comparison part subjected to the same processing as the heat reaction part at a location.

  By adopting this configuration, a change in the heat reaction part (heat reaction part) can be obtained by comparing the heat reaction part with the comparison part (generally having the same appearance as the heat reaction part before heating). Makes it easy to notice the heated traces. Therefore, even if the whitening mark is erased, it is possible to make it easier to find out.

However, in the vicinity of the engaging portion 170 (the first position engaging portion) which constitutes the "B caulking portion", the engaging portion 170 which constitutes the "C caulking portion" is connected to the first position engaging portion 170. It is preferable to provide them in parallel (the engagement directions are parallel to each other). As a result, when switching the “crimped part” to be used from the “B-crimped part” to the “C-crimped part”, it is sufficient to move the movable body for engagement 220 a short distance by a simple trajectory (straight trajectory). As a result, the design of the case holder 200 is facilitated. Further, the number of "C crimped parts" installed is not particularly limited. In this embodiment, as shown in FIG. 15 and FIG. 16, “C crimped portion” (below the “B crimped portion”) in the vicinity of the center of the right edge of the gaming machine substrate case 100 etc. One second position engaging portion) is provided.

  By the way, because regular opening by inspection organization etc. is not limited to once, in addition to "C-crimped part", "D-crimped part" and "E-crimped part" in the conventional gaming machine substrate case etc. May be provided. In this case, the "C-crimped part" is broken in the second regular opening, the "D-crimped part" is used in the second re-sealing, and the "C-crimped part" is used in the third regular opening. The “D-crimped part” is broken, and the “E-crimped part” is used at the third resealing. In the gaming machine substrate case 100 and the case holder 200 of the present embodiment, the portions corresponding to the “D-crimped portion” and the “E-crimped portion” are not provided, but the gaming machine substrate case 100 and the case holder 200 It is also possible to provide a portion corresponding to "D-crimped part" or "E-crimped part".

  In the case where the "D crimped portion" or the "E crimped portion" is provided, the engaged movable body 220 is used at the first position used as the "B crimped portion" and the second position used as the "C crimped portion" It is possible to move not only to the position but also to the third position used as the "D-crimped part" and the fourth position used as the "E-crimped part", and to be engaged in the third position. This can be realized by providing a third position engaging portion that engages with the compatible 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 in parallel in the vicinity.

  When the engagement portion 170 (second position position engagement portion) of the “C crimped portion” and the movable body 220 for engagement are engaged in the above-described procedure, the resealing procedure 3 is completed. In this state, although the "C caulking 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-crimped part” to be done is not broken as the “A-crimped part” because it has already been destroyed.

  However, the gaming machine substrate case 100 of this embodiment has a structure in which the cover member 110 can not 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 normal However, as shown in FIG. 14, the case holder 200 has the upper wall portion 204, and when the resealing procedure 3 is completed, the upper wall portion 204 serves as the cover member 110. Is pressed from the upper side to restrict the upward slide of the cover member 110. For this reason, in a state where the gaming machine substrate case 100 is assembled to the case holder 200, the cover member 110 can not be removed from the base member 120 even if the "A caulking portion" does not function. There is.

5.4 Resealing Procedure In 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 described above.

5.5 After Completion of Resealing Procedures 1 to 4 When all of the resealing procedures 1 to 4 described above are completed, the gaming machine is ready to be installed in the hall. When suspicious behavior is observed in the gaming machine installed in the hall, or a failure or suspicious point is recognized in the electronic substrate 500, the electronic substrate 500 and the like are returned to the manufacturer.

In addition to being ineffective, as described above, the "A crimped portion" is already broken and no longer functional, so 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 can be removed from the base member 120. Therefore, in the gaming machine substrate case 100 in this state, the sealing function of the electronic substrate 500 can not be achieved. Therefore, when the gaming machine substrate case 100 is returned to the manufacturer in this state, if the fraudulent action is taken such as the ROM of the electronic substrate 500 being replaced with a forged ROM in the middle of the return path, It becomes difficult to notice. In addition, even if the manufacturer inspects the returned electronic substrate 500 and finds an illegal act such as a forged ROM exchange, it is made in the middle of the return route whether the illegal act is done in the hall or not It becomes difficult to determine if it is a thing. Therefore, in the return procedure 3, the cover member 110 and the base member 120 are engaged again, and the electronic substrate 500 is sealed again by the gaming machine substrate case 100.

  In the present 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 separated. The engaged portion 180 is engaged with the engaged portion fitting port 110b provided at the right end 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 slide operation) as assembling the cover member 110 to the base member 120 in the assembly procedure 2. The member 110 and the base member 120 are engaged again. When the cover member 110 is operated to slide downward, the engaging portion 170 (the engaging portion 170 of the portion indicated by the symbol “F” in FIG. 7A) provided at the upper right corner of the base member 120 , Pushed into and engaged with the aforementioned engaged portion 180. The engaged portion 180 is provided with a flange around its periphery, and has a form in which it can not pass through the engaged portion insertion port 110b, so the engaging portion 170 engages with the engaged portion 180. After the engagement, the cover member 110 can not be removed from the base member 120 unless the engaged portion 180 and the engaging portion 170 engaged therewith are broken or the like.

  At this time, in the section where the engaged portion 180 (FIG. 31) in the base member 120 is separated, the hole (cut hole) is open. However, in the gaming machine substrate case 100 according to the present embodiment, the partition wall portion 126 (see FIG. 30A described later) of the base member 120 and the partition wall portion 116 of the cover member 110 (FIG. In the inside of the gaming machine substrate case 100, the space which communicates with the outside through the above-mentioned cutout hole is divided by the space b) into a space in which the electronic substrate 500 is accommodated. For this reason, the electronic board 500 can not be accessed through the above-mentioned cut holes unless the partition wall portion 116 or the partition wall portion 126 is broken or the like.

  By the way, in the game machine industry, when returning an electronic substrate or the like to a manufacturer, it is called "F-crimp" to engage the cover member and the base member in the gaming machine substrate case that accommodates the electronic substrate or the like. A portion of the gaming machine substrate case to which "F-crimping" is applied is called "F-crimping portion". "F-crimping unit" prevents the gaming machine substrate case from being opened illegally when returning the electronic substrate etc. to the manufacturer (if the gaming machine substrate case is opened illegally, its trace will remain Has become part of.

  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 caulking portion”. Therefore, in the present specification, the engagement between the engagement portion 170 engaged in the return procedure 3 and the engaged portion 180 is referred to as “F caulking”, and the engagement in the gaming machine substrate case 100 is performed. The part engaged by the part 170 and the to-be-engaged part 180 may be called "F crimping part." In the drawings of the present application, a portion corresponding to "F caulked portion" is indicated using a symbol "F".

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

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

6.5 After Completion of the Return Procedures 1 to 4 The manufacturer cancels the “F-crimped portion” in the gaming machine substrate case 100 returned from the hall or the like, and the base member 120 is processed similarly to the normal opening procedure 3 above. After the cover member 110 is slid upward, the cover member 110 is removed from the base member 120 by pulling it forward, and then the electronic substrate 500 is removed in the same procedure as the regular opening procedure 4 described above. The electronic board 500 is removed from the cover member 110, and the electronic board 500 is inspected and repaired. The release of the “F-crimped part” destroys the regular opening destruction part 100 a ₃ (FIG. 7A) provided on the part covering the “F-crimped part” in the gaming machine substrate case 100, and the destroyed part , And a cutting tool such as a nipper is inserted to cut the engaging portion 170 of the "F caulking portion".

7. Specific structure of the gaming machine substrate case and its peripheral members The gaming machine substrate case of this embodiment is the above-mentioned "3. Assembly procedure of gaming machine substrate case etc.", "4. gaming machine substrate case, etc. The game machine is assumed to use as described in the regular opening procedure of “5. Resealing procedure of substrate case etc. for gaming machine” and “6. Manufacturer return procedure of electronic substrate etc.” The substrate case 100, the case holder 200 and the like are subjected to various devices suitable for such a usage mode. Hereinafter, these devices will be described in detail.

However, in the following description, for convenience of explanation, the terms “α direction”, “α ⁺ side” and “α ⁻ side”, and “β direction”, “β ⁺ side” and “β ⁻ side” May be used. The meaning of these terms is as shown in FIG. FIG. 35 shows that the engaging portion of the engaging portion 170 provided as the “A crimped portion” on the base member 120 is pushed against the engaged portion 130 provided on the cover member 110 as the “A crimped portion”. It is the figure which looked at the mode of a displacement of the engaging part 170 at the time of pushing in and engaging in the back direction, from the pushing direction back side (z axial direction positive side).

That is, it is perpendicular to the pressing direction (z-axis direction) of the engaging portion 170 with respect to the engaged portion 130 and 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). The parallel direction is called "alpha direction", one side in the alpha direction is called "alpha ⁺ side", and the other side in the alpha direction is called "alpha ^- side". In the example of FIG. 35 (A crimp), the positive side in the x-axis direction is the “α ⁺ side”, and the negative side in the x-axis direction is the “α ⁻ 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 referred to as "β side". In the example of FIG. 35 (A crimp), the positive side in the y-axis direction is "beta ⁺ side", and the negative side in the y-axis direction is "beta ^- side".

Where the terms "alpha direction", "alpha ⁺ side" and "alpha ^- side", and "beta direction", "beta ⁺ side" and "beta ^- side" mean, except for "A crimped part" The same applies to the "B-crimped part" and the "C-crimped part". However, in the present embodiment, the pushing direction of the engaging portion 170 is different between the “A caulking portion” and the “B caulking portion” and the “C caulking portion”. The relationships with the axes, y-axis and z-axis are also different. Specifically, in the "B crimped portion" and the "C crimped 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 It is "alpha ⁺ side".

In addition, in the "A caulking portion", as shown in FIG. 13, fragile portion 100b ₁ is provided with the engaged portion 130 side, y-axis direction positive side is "beta ⁺ side" (fragile portion 100b ₁ While the y-axis direction negative side is the “β ⁻ side” (the side closer to the fragile portion ₁₀₀ b ₁ ) on the side far from the surface), in the “B crimped portion” and “C crimped portion”, FIG. 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, take care. This point will be described in detail later.

8. Board case for game machine (cover member and base member)
First, the gaming machine substrate case 100 will be described. As described above, the gaming machine substrate case 100 is configured by assembling the cover member 110 on the front side of the base member 120.

FIG. 22 is a view showing the cover member 110 as viewed from the front. FIG. 23 is a view showing the cover member 110 as viewed from the rear. FIG. 24 shows the engaged portion 130 provided as the “A crimped portion” on the cover member 110 as (a) viewed from the front upper right and (b) viewed from the rear upper left. FIG. FIG. 25 is a six-sided view of the engaged portion 130 in FIG. 24 with the surface on the z axis direction negative side in the same drawing as the front.

  As shown in FIG. 21, the cover member 110 of the present embodiment is provided so as to protrude rearward from the left edge and the right edge on both sides of the front wall 111 having a rectangular shape in front view and the front wall 111, respectively. Left wall portion 112 and right wall portion 113, upper wall portion 114 and lower wall portion 115 provided to project rearward from the upper edge portion and lower edge portion of the front wall portion 111, and the front wall portion 111; And a partition wall 116, 117 and the like for partitioning the rear space of the The upper wall portion 114 not only covers the upper surface of the cover member 110, but also functions as a "force-bearing wall portion" that abuts against a push-in displacement restricting portion 140 (Fig. 12) described later. For this reason, in the following, the upper wall portion 114 may be referred to as a “bearing wall portion 114”. Further, the partition wall portions 116 and 117 are not merely used as a simple partition, but also guide when the cover member 110 is vertically slid with respect to the base member 120 in the above-mentioned assembly procedure 2 and resealing procedure 2 and the like. It also serves as a functional part.

  As shown in FIG. 23, an engaged portion 130 is provided on the back side (rear surface side) of a portion of the front wall portion 111 that covers the “A crimped portion”. The engaged portion 130 is an engaging portion 170 provided on the side of the base member 120 in the case of “A crimping” in which the cover member 110 is assembled to the base member 120 (reference numeral “A” in FIG. (The engagement portion 170) of the portion indicated by (1) is a portion for engaging and engaging.

As will be described later, the engaged portion 130 of this embodiment has an α ⁺ -side engaged wall portion 131 (FIG. 24) located on the α ⁺ -side (the positive side in the x-axis direction) and an α ⁻ -side (x-axis) alpha located toward the negative side) ^- where having a side the engagement wall portion 132 (FIG. 24), alpha ⁺ side and a base end portion of the engagement wall portion 131 alpha ^- group on the side the engagement wall portion 132 end and a (front end), is formed integrally with the backside (rear side) of the weak portion 100b ₁ shown in FIG. 22. In the cover member 110 of this embodiment includes a fragile portion 100b ₁ of alpha ⁺ side the engaging wall portion 131 is provided, alpha ^- side the engaging wall portion 132 is allowed to divide the weakened portion 100b ₁ provided . How to integrate engaged portion 130 with respect to weakened portion 100b ₁ is not particularly limited, in the cover member 110 of this embodiment has been formed separately from the fragile portion 100b ₁ (cover member 110) By subjecting the engaged portion 130 to the cover member 110 by vibration welding, the engaged portion 130 is integrated with the fragile portion ₁₀₀ b ₁ .

The above fragile portion 100b _1, rather than the surrounding site by a thermoplastic resin has a brittle-formed portion, the while attempting to release illegally engagement of the engaging portion 170 with respect to the engaged portion 130 This portion is a portion for leaving a trace (plastic deformation such as whitening) caused by an external force applied to the engaging portion 130 (a portion corresponding to “a whitening portion at the time of fraud release” described later). That is, the fragile portion 100b _1, when unauthorized release the engagement between the engaging portion 170 and the engaged portion 130, and has a portion for causing plastic deformation of whitening or the like intentionally. Therefore, in the present embodiment, even when the gaming machine substrate case 100 is attached to a predetermined location in the gaming machine chassis, the fragile portion 100b ₁ can be easily viewed from the outside of the gaming machine substrate case 100. as it has been set the location and orientation to provide the fragile portion 100b _1. Specifically, as shown in FIG. 22, the front wall portion 111 of the cover member 110 (the front wall portion 111 is disposed forward when the gaming machine substrate case 100 is attached to the gaming machine case). in the normal direction of the fragile portion 100b ₁ is, so as to be substantially parallel to the longitudinal direction (y-axis direction) it is provided with a fragile portion 100b ₁ of the "a caulking portion". Further, in the present embodiment, as described later, although the fragile portion 100b ₁ (FIG. 17) is also provided to the “B crimped portion” and the “C crimped portion”, the “B crimped portion” and the “C crimped portion” are provided. The same applies to the case where the normal direction of the fragile portion ₁₀₀ b _{1 of} “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). For this reason, as shown in FIG. 2, when the gaming machine substrate case 100 is attached to a predetermined portion of the casing main body 10a (game machine casing), the front wall portion 111 of the cover member 110 is the front. It is arranged in a state of facing (the negative side in the y-axis direction in FIG. 2). In addition, as shown in FIG. 2, when the front door 10 b of the gaming machine case is open, the front wall portion 111 of the cover member 110 opens the open surface 10 a ₂ of the case body 10 a (opens the front door 10 b (See the plane indicated by the alternate long and short dash line in FIG. 2.) It is visible from the side. 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, fragile portion 100b ₁ provided in the front wall portion 111 of the cover member 110 can be inspected person to easily view.

As described above, by not interposing an obstacle that blocks the line of sight between the member providing the fragile portion ₁₀₀ b ₁ (whitening portion at the time of fraud release) and the open surface 10 a ₂ of the casing main body 10 a, the fragile portion ₁₀₀ b ₁ It becomes possible for an inspector to easily check the whitening section). The same applies to the case where the configuration according to the present invention is adopted for another member (member other than the main control board unit 30; for example, the sub control board unit 31 of FIG. 2 etc.) attached to the casing main body 10a. is there. When the configuration according to the present invention is adopted not by the housing body 10a but by a member attached to the front door 10b (for example, the liquid crystal unit 32 or the connector unit 34 in FIG. 2), the fragile portion 100b ₁ ( a member providing a fraudulent cancellation whitened part), when closing the open surface 10b ₂ (front door 10b of the front door 10b, indicated by a two-dot chain line in the plane. Figure 2 that overlaps the open face 10a ₂ of the housing body 10a By not interposing an obstacle that blocks the line of sight between the face and the face), the inspector can easily confirm the fragile portion 100b ₁ (whitening portion at the time of fraud release). The normal direction of the fragile portion ₁₀₀ b ₁ (whitening portion at the time of fraud release) is substantially parallel to the normal direction of the open surface 10 a ₂ of the casing main body 10 a (the fragile portion ₁₀₀ b 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 In the case where the whitening portion is provided), it is preferable.

A method of forming brittle than the surrounding region the fragile portion 100b ₁ 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. In this specification, the engagement provided on the gaming machine member (including not only the cover member 110 and the base member 120 but also other members such as the case holder 200) as in the fragile portion 100b ₁ described above. Improper engagement between the engaging portion and the engaged portion around the portion where the engaging portion or the engaged portion is provided in the portion, the engaged portion, or the gaming machine member The part which produces plastic deformation, such as whitening, in the case of cancellation | release may be called a "corruption cancellation whitening part."

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 too thick a fragile portion 100b _1, there is a possibility that hardly remain traces the fragile portion 100b ₁ when 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, if the fragile portion 100b ₁ is made too thin, when engaging the engaging portion 170 with the engaged portion 130 regularly in a game machine manufacturing plant or the like as well as in the case of unauthorized access The plastic deformation is likely to occur in the fragile portion 100b ₁ also when performing the attaching procedure 2). 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.

Moreover, (the area of one fragile portion 100b ₁₎ the area of each of the 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 wide, the fragile portion 100b ₁ becomes too easy to be broken, and plastic deformation is likely to occur in the fragile portion 100b ₁ even in cases other than unauthorized access . Thus, fragile portion 100b ₁ is preferably limited to providing a narrow 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 the dimension of the engaged portion 130 can not be made much smaller, it is preferable to divide the fragile portion 100b1 into a plurality of places for _one engaged portion 130 as in the cover member 110 of the present embodiment.

As long as the engaged portion 130 can engage the engaging portion 170 provided on the side of the base member 120 (the engaging portion 170 of the portion indicated by the symbol “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 described later, the engagement portion 170 is located on the α ⁺ side (the positive side in the x-axis direction), the α ⁺ β ⁺ side engagement portion 172 and α Because it is composed of the ⁺ β ⁻ side engaging portion 173 and the α ⁻ β ⁺ side engaging portion 174 and the α ⁻ β ⁻ side engaging portion 175 located on the α ⁻ side (the negative side in the x-axis direction), as shown in FIGS. 24 and 25, the engaging portion 130 of the cover member 110 side, and alpha ⁺ side (x-axis positive direction side) in placed the alpha ⁺ side the engaging wall portion 131, alpha ^- 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 α ⁻ The β ⁺ -side engagement portion 174 and the α ^- β ^- side engagement portion 175 are engaged.

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

Further, as shown in FIG. 24B, the engaged portion 130 of this embodiment includes the front end portion (rear end portion) of the α ⁺ -side engaged wall portion 131 and the α ⁻ -side engaged wall A connecting wall 133 is also provided to connect the front end (rear end) of the portion 132. Furthermore, in the engaged portion 130, the base end (front end) of the α ⁺ -side engaged wall 131 and the base end (front end) of the α ^-- side engaged wall 132 are connected. A bottom wall 134 is also provided. Therefore, as shown in the front view of FIG. 25, the engaged portion 130 has a frame shape in a front view, and is in a state in which the rigidity is enhanced. Therefore, it is possible to prevent the engagement portion 170 from being disengaged from the engaged portion 130 by unintended deformation of the engaged portion 130 which engages the engaging portion 170.

  Further, in the cover member 110 of the present embodiment, as shown in FIG. 11, the bearing wall is located at the front side (z-axis direction negative side) of the engaging portion 170 as viewed from the bearing wall 114. The push-in displacement restricting portion 140 is provided in a state of being separated from the portion 114 by a predetermined distance. When the push-in displacement restricting portion 140 pushes and engages the engaging portion 170 with respect to the engaged portion 130, the push-in displacement restricting portion 140 is displaced rearward in the pushing direction (z-axis direction positive side) to contact the bearing wall portion 114. By being in contact with each other, it is a portion for restricting the displacement of the engaged portion 130 to the rear side (z-axis direction positive side) in the pushing direction. More specifically, the push-in displacement control unit 140 is a part for exerting the following function.

That is, as described above, the engaged portion 130 is integrally formed 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 improperly pulled out. Where the engaging portion 170 is properly engaged with the engaged portion 130 in the manufacturing plant of the gaming machine, etc., as well as at the time of tampering with the fragile portion 100b ₁ Also when performing the assembly procedure 2), there is a possibility that traces such as whitening may remain. In particular, when the engaging portion 170 is pushed into and engaged with the engaged portion 130, the pressing force by the engaging portion 170 is also applied to the engaged portion 130, and the engaged portion 130 is engaged. 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 countermeasure is taken against the above problems, there is a possibility that the gaming machine substrate case 100 for which the unauthorized opening has not been performed may be mistaken as an unauthorized opening.

In this point, in the gaming machine substrate case 100 according to the present embodiment, when the engaging portion 170 is pushed into and engaged with the engaged portion 130 by providing the above-described push-in displacement restricting portion 140, 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 from the engaged portion 130 to release the engagement between the engaging portion 170 and the engaged portion 130, the above-mentioned push-in displacement restricting portion 140 is engaged with the engaged portion. When the engaging portion 170 is pulled out from the engaged portion 130, the portion 130 is displaced to the side in the pressing direction (the z-axis direction negative side) together with the portion 130 and does not abut on other portions such as the bearing wall 114. It does not exhibit the function of restricting the displacement of the engaged portion 130 to the front side in the pushing direction. For this reason, when trying to pull out the engaging portion 170 illegally from the engaged portion 130, the whitening etc. of the fragile portion ₁₀₀ b ₁ (the occurrence of a mark of unauthorized removal) is not inhibited by the pressing displacement regulating portion 140.

In the gaming machine substrate case 100 of the present embodiment, the fragile portion 100b is formed when the engaging portion 170 is pushed against the engaged portion 130 by providing the above-described push-in displacement restricting portion 140 in the above-described manner. _Although it is difficult to cause plastic deformation such as whitening in ₁₎ , the purpose of seemingly contradicting is that plastic deformation such as whitening tends to easily occur in the fragile portion 100b ₁ when the engaging portion 170 is pulled out from the engaged portion 130 Have succeeded in achieving at the same time.

The push-in displacement restricting portion 140 is engaged with the engaged portion 130 at a position on the cover member 110 on the front side in the pushing direction of the engaging portion 170 (the z-axis direction negative side in FIG. 11) as viewed from the bearing wall portion 114. As long as it is integrally provided (provided in a state of being displaced together with the engaged portion 130), the specific installation place is not limited. The pressing displacement restricting portion 140 is pressed directly to the engaging portion 170 (the pressing force of the engaging portion 170 is directly applied from the engaging portion 170 to the pressing displacement restricting portion 140), whereby the pressing direction is obtained. It may be displaced to the back side, and is not directly pressed by the engaging portion 170 (the pressing force of the engaging portion 170 is the α ⁺ -side engaged wall portion 131 or α ⁻ in the engaged portion 130. It may be made to be indirectly added to the pushing displacement regulating portion 140 via the side engaged wall portion 132 or the like.

As shown in FIG. 24A, the pressing displacement restricting portion 140 of the present embodiment is provided in a portion of the connecting wall portion 133 of the engaged portion 130 that extends on the back side in the pressing direction (the positive side in the z-axis direction) It has a convex shape. The push-in displacement restricting portion 140 is in a state of protruding toward 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 pushing the engaging portion 170 into the engaged portion 130, the surface of the end portion on the near side (z-axis direction negative side) in the pushing direction of the pushing displacement restricting portion 140. A portion (α in FIG. 33) on the β ⁺ side (the positive side in the y-axis direction) of the engaging portion 170 in 140a (hereinafter sometimes referred to as “engaging portion abutted surface of the pressing displacement regulating portion”). ^{The +} β ⁺ side engaging portion 172 and the α ⁻ β ⁺ side engaging portion 174 are in contact with each other. Therefore, the behavior of the α ⁺ β ⁺ side engaging portion 172, the α ⁻ β ⁺ side engaging portion 174 and the pressing displacement restricting portion 140 when the engaging portion 170 is pushed into the engaged portion 130 is stabilized. Is possible.

Moreover, in the present embodiment, as shown in FIG. 24A and the left side view of FIG. 25, the engaging portion abutted surface 140 a of the pressing displacement regulating portion 140 is located on the front side in the pressing direction (z in FIG. It is inclined so as to protrude to the β ⁻ side (the negative side in the y-axis direction in FIG. 24) from the negative side in the axial direction to the rear side in the pushing direction (the positive side in the z-axis direction in the same figure). Therefore, when the engaging portion 170 is pushed into and engaged with the engaged portion 130, the α ⁺ β ⁺ side engaging portion 172 and the α ⁻ β ⁺ side engaging portion 174 are solid lines in FIG. After being displaced from the initial position shown by the part to the first displacement position shown by the hatched hatching in the same figure, it is further guided by coming into contact with the engaging part abutted surface 140a of the pushing displacement restricting part 140 After being elastically displaced to the β ^- side (the negative side in the y-axis direction) up to the second displacement position shown by the broken line in FIG. 35, it elastically returns to the initial position.

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

In addition, as shown in FIG. 13, after engaging the engaging portion 170 with the engaged portion 130, a portion on the β ⁺ side (the positive side in the y-axis direction) in the engaging portion 170 (α ⁺ β in FIG. 33) ^The push-in displacement restricting portion 140 is positioned in the gap between the ⁺ side engaging portion 172 and the α ⁻ β ⁺ side engaging portion 174). For this reason, even if it is attempted to displace the α ⁺ β ⁺ side engaging portion 172 and the α ⁻ β ⁺ side engaging portion 174 in directions approaching each other in the α direction (x-axis direction) for the purpose of unauthorized release of engagement. The push-in displacement regulating unit 140 is in the way. That is, it is also possible to cause the pressing displacement regulating unit 140 to exhibit the same function as the proximity displacement regulating unit 150 described later.

The size of the gap _{G 1} between the push-displacement restricting portion 140 and the bearing wall portion 114 (FIG. 11) 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 can not restrict the displacement of the engaged portion 130 to the rear 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 same shall apply hereinafter)) is 3 mm or less. The gap _{G 1} is preferable to be 2mm or less, and more preferably 1mm or less.

Furthermore, in the present embodiment, as shown in FIG. 24 (b), 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 (z-axis direction positive side) The portion 150 is provided in a convex shape. The proximity displacement restricting portion 150 is in a state of protruding toward the side where the engaging portion 170 is inserted (the y-axis direction positive side). For this reason, as shown in FIG. 13, after engaging the engaging portion 170 and the engaged portion 130, a portion on the β ⁻ side (the y-axis direction negative side) in the engaging portion 170 (α in FIG. 33 ^The proximity displacement restricting portion 150 is positioned in the gap between the ⁺ β ^- side engaging portion 173 and the α ^- β ^- side engaging portion 175). That is, even if it is intended to displace the α ⁺ β ⁻ side engaging portion 173 and the α ⁻ β ⁻ side engaging portion 175 in the α direction (x-axis direction) so as to release the engagement improperly, The proximity displacement restricting portion 150 is in the way.

As shown in FIG. 12, when pushing the engaging portion 170 into the engaged portion 130, the surface 150a of the end portion of the proximity displacement regulating portion 150 on the near side (z-axis direction negative side) in the pressing direction (below And the engaging portion 170 is in contact with the “contact portion contact surface of the proximity displacement restricting portion”. In this respect, in the present embodiment, as shown in FIG. 24 (b) and the left side view of FIG. 25, the engaging portion abutted surface 150 a of the proximity displacement restricting portion 150 It is inclined so as to protrude to the β ⁺ side (the y-axis direction positive side in FIG. 24) from the z-axis direction negative side to the pressing direction back side (the z-axis direction positive side in FIG. 24). 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 solid lines in FIG. After being displaced from the initial position shown by the part to the first displacement position shown by the hatched hatching in the same figure, it is further guided by coming into contact with the engaging part abutted surface 150a of the proximity displacement restricting part 150. After being elastically displaced to the β ⁺ side (the positive side in the y-axis direction) up to a second displacement position indicated by the broken line in FIG. 35, the sheet is elastically returned to the initial position. That is, in the gaming machine substrate case 100 of the present embodiment, when the engaging portion 170 is pushed into and engaged with the engaged portion 130, the α ⁺ β ⁺ side engaging portion 172 and the α ⁻ β ⁺ Not only the side engaging portion 174 but also the α ⁺ β ⁻ side engaging portion 173 and the α ⁻ β ⁻ side engaging portion 175 are elastic in both the α direction (x axis direction) and the β direction (y axis direction) It is supposed to be displaced. Thus, by complicating the engaging structure of the engaging portion 170 and the engaged portion 130, the engaging portion 170 engaged with the engaged portion 130 is unfairly removed from the engaged portion 130. It has become possible to make things 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. Therefore, a plate-like portion perpendicular to the fragile portion 100b ₁ in the gaming machine substrate case 100 or the like (for example, the bearing wall portion 114 described above, the α ⁺ -side engaged wall portion 131 of the engaged portion 130, The α ^- side engaged wall portion 132 etc.) is less visible than the fragile portion 100b ₁ and hardly noticed even if plastic deformation such as whitening occurs in the plate-like portion, the plate-like portion There is a possibility that an unauthorized access to the engaged portion 130 may be attempted by using the

  In this respect, in the present embodiment, as shown in FIG. 28, the engagement member protection member 160 shown in FIGS. 26 and 27 is attached to the engagement member 130, and the engagement member 130 is engaged. By protecting it, such unauthorized access is prevented. FIG. 26 is a view showing the engagement member protection member 160 as seen from (a) front diagonally upper right and (b) rear diagonally upper left. FIG. 27 is a six-sided view in which the face on the negative side in the z-axis direction in FIG. FIG. 28 is a view showing a state where the engagement portion protection member 160 of FIG. 26 is attached to the engagement portion 130 of FIG. 24 as viewed from the rear upper left.

As shown in FIG. 26, the engagement member protection member 160 of this embodiment includes a back surface protection part 161, a side surface protection part (left side surface protection part 162 and right side surface protection part 163), and a flat surface protection part 164. It is a metal member equipped 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 portions 130. It is a plate-like part that covers. The side surface protection portions 162 and 163 are surfaces substantially perpendicular to the fragile portion ₁₀₀ b ₁ of the outer surfaces of the engaged portions 130 and substantially parallel to the pressing direction of the engagement portion 130 (x-axis direction positive side or x It is a plate-like portion that covers the surface facing the axial negative side, hereinafter referred to as the “side surface of the engaged portion”. The flat surface protection portion 164 is a surface on the opposite side to the surface integrally provided on the fragile portion 100b ₁ among the outer surfaces of the engaged portions 130 (a surface facing the positive side in the y-axis direction. Hereinafter, “engaged portions It is a plate-like part that covers the

By protecting the engaged portion 130 with the engaged portion protecting member 160, the fraudulent from the direction perpendicular to the normal direction (viewer's line of sight) of the fragile portion ₁₀₀ b _{1 with} respect to the engaged portion 130. It becomes possible to prevent access. Further, as will be described later, the engaged portion protection member 160 is fixed to the engaged portion 130 or the fragile portion 100b ₁ or the like, and the engaged portion using a tool such as a driver or a drill. When a hole is made in the protection member 160, the external force applied from the tool to the engagement portion protection member 160 is fragile from the engagement portion protection member 160 via the engagement portion 130. indirectly to parts 100b _1, or consists of the engaged portion protection member 160 to be directly added to the fragile portion 100b _1, it can cause plastic deformation of the whitening such 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, by making the trace of unauthorized access to a portion that is difficult for the inspector to easily see in a portion that is easily visible to the inspector, it is easy for the inspector to find the trace of unauthorized access to the portion that is difficult to visually check Can.

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 cover only the back surface, the left side surface, the right side surface, and a part of the flat surface of the engaged portion 130 It is also good. However, in the engagement member protection member 160 according to this embodiment, the back surface protection member 161, the left side surface protection member 162, the right side surface protection member 163, and the flat surface protection member 164 respectively The left side, the right side and substantially the entire plane are covered. Further, 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 may be formed by joining separate members. However, the engagement member protection member 160 in this 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 portion protection member 160 is not only excellent in strength that is less likely to be damaged, etc., but also of the protection portions 161, 162, 163, and 164 that constitute the engaged portion 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.

  Further, in the engaged portion protection member 160 according to this embodiment, as shown in FIG. 26, the left side surface protection portion 162 and the right side surface protection portion 163 are provided with the fitting pieces 160a. The fitting piece 160a is, as shown in FIG. 28, a fitting piece receiving portion provided on the engaged portion 130 when the engaged portion protecting member 160 is attached to the engaged portion 130. It is fitted in 130b. Thus, the engaged portion protection member 160 can be positioned with respect to the engaged portion 130. The way in which the fitting piece 160a is provided is not particularly limited, but in the present embodiment, the metal plate forming the left side protection portion 162 and the right side surface protection portion 163 is provided on the inner surface side of the engagement portion protection member 160. By cutting and raising, the fitting piece 160a is formed. For this reason, the fitting piece 160 a is elastically displaceable with respect to the left protecting portion 162 and the right side protecting portion 163. Therefore, when the fitting piece 160a is fitted in the fitting piece receiving portion 130b, the fitting piece 150a can be kept in close contact with the engaged portion 130. Therefore, not only the rattling of the engaged portion protection member 160 can be prevented, but also the external force applied to the engaged portion protection member 160 can be reliably transmitted to the engaged portion 130. ing.

Furthermore, in the engaged portion protection member 160 according to the present embodiment, as shown in FIG. 28, the fitting direction front side of the engaged portion protection member 160 with respect to the engaged portion 130 (y The axially positive side is inclined in such a direction as to largely protrude on the inner surface side of the side surface protection portions 162 and 163. For this reason, as shown in FIG. 28A, when attaching the engaged portion protection member 160 to the engaged portion 130, protection of the engaged portion is prevented without causing a large resistance. The member 160 can be pushed to a desired position. Therefore, when mounting the engaged portion protection member 160, it is difficult to transmit the force for pushing the engaged portion protection member 160 to the fragile portion 100b _1, and the fragile portion at the time of mounting the engaged portion protection member 160. it is possible to prevent the whitening and the like of 100b _1.

On the other hand, as shown in FIG. 28 (b), when trying to pull out the engagement portion protection member 160 mounted on the engagement portion 130 to the front side (the y axis direction positive side) in the mounting direction, The end in the mounting direction near side (the y-axis direction positive side) of the fitting piece 160a is engaged with the fitting piece receiving portion 130b. That is, the engaged portion protection member 160 is in a state where it is difficult to remove the engaged portion 130 from the engaged portion 130. Also, when trying to pull out the engaged portion protection member 160 forcibly from the engaged portion 130, the pulling force is easily transmitted to the fragile portion 100b ₁ through the engaged portion 130, and the fragile portion 100b. Plastic deformation such as whitening is likely to occur in ₁ ).

  Furthermore, in the engaged portion protection member 160 according to the present embodiment, as shown in FIG. 27, the rising portion 160 b is provided at the front edge of the plane protection portion 164. As shown in FIG. 28 (b), the rising portion 160 b is located 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 part is in contact with the surface on the side (z-axis direction negative side). Thus, the engaged portion protection member 160 attached to the engaged portion 130 is not only in the mounting direction (y-axis direction) of the engaged portion protection member 160 but also in the engagement portion 170. It is possible to prevent backlash in the pressing 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 plastic deformation such as whitening more noticeable, these whitening portions at the time of fraud release are generally formed of a transparent thermoplastic resin, like the cover member 110, the base member 120, and the like. However, even if whitening occurs in the whitening part at the time of fraud release, the trace of the fraudulent opening may be erased by heating the whitened part with a dryer or the like to make it transparent. In this respect, in the gaming machine substrate case 100 and the like of the present embodiment, by providing the heat reaction portion whose appearance is deteriorated by heating in the whitening portion at the time of fraud release, the presence or absence of the act of erasing traces of fraud opening as described above. Can be determined from the appearance of the heat reaction part. Specifically, as shown in FIG. 22, the heat reaction portion 100c is provided in the fragile portion 100b ₁ (whitening portion 100b at the time of fraud release), and as shown in FIG. 33, the proximal end of the rod-like protrusion of the engagement portion 170. The heat reaction unit 100 c is provided also in the unit 100 b ₂ (whitening unit 100 b at the time of fraud release).

The thermal reaction part 100c is not particularly limited as long as the appearance is deteriorated by heating.
The appearance of the thermal reaction portion 100c may be altered as follows.
(1) The thermal reaction part 100c that was visible or easy to see before heating becomes invisible or hard to see after heating.
(2) The thermal reaction part 100c that appeared 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 illustrated.
In the following, the thermal reaction part whose appearance is degraded in the aspect of the above (1) may be referred to as "heat elimination type thermal reaction part", and the thermal reaction part whose appearance is altered in the aspect of the above (2) It may be called "heat reaction type of heat mutation type". The heat reaction part 100c of the present embodiment is of the heating and erasing type.

  The thermal reaction portion 100c may be provided in a simple dot shape, a simple linear shape, or a simple surface shape, but when provided in a pattern consisting of characters, figures, symbols, or a combination thereof, the thermal reaction portion 100c Can be easily identified. As shown in FIGS. 22 and 33, the thermal reaction unit 100c of the present embodiment is a graphic character string (character string of “ABC”) composed of alphabets.

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 one.
However, in this case, after the fraud release
(1) The separate member provided with the heat reaction unit 100c is cleanly separated from the whitening unit 100b at the time of fraud release.
(2) The whitening part 100b at the time of fraud release is heated at the whitening part at the time of fraud release (at this time, the separate member provided with the heat reaction part 100c is not heated), and the whitening mark of the place is erased.
(3) The separate member provided with the heat reaction part 100c is fixed to the original place in the whitening part 100b at the time of fraud release.
When the removal of the whitening mark is performed according to the above procedure, the heating history does not remain in the heat reaction unit 100c.

  For this reason, it is preferable that the thermal reaction part 100c be provided in a state where it can not be separated from the surface of the whitening part 100b at the time of fraud release (formed integrally with the surface of the whitening part 100b at the fraud release). As a result, it becomes possible to make it impossible to erase the whitening mark according to the procedure of the above (1) to (3). The thermal reaction part 100c of this embodiment is also integrally formed on the surface of the whitening part 100b at the time of fraud release.

The method of integrally forming the thermal reaction part 100c with respect to the whitening part 100b at the time of fraud release is also not particularly limited.
As an integral formation method of thermal reaction part 100c to whitening part 100b at the time of fraud release,
(1) A method of forming a recess or a projection on the surface of the whitening portion 100b at the time of fraud release (the recess or the projection may be formed, for example, by engraving, fogging, embossing, etc.) (2) by heating The method of applying the paint etc. which change in appearance on the surface of whitening part 100b at the time of fraud release (3) The method etc. of mixing the pigment etc. which deteriorate by heating in the molding material of whitening part 100b at the time of fraud release are illustrated.

FIG. 29 is a perspective view of a portion of the whitening portion 100b at the time of fraud release with the thermal reaction portion 100c provided, which is cut along a plane perpendicular to the surface (front surface) of the whitening portion 100b at the fraud release. 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 minute convex portions 100c ₁ etc. become prisms and the light emitted from each minute convex portion 100c ₁ is dispersed and a portion appearing iridescent appears) or when heated, the minute convex portions 100c ₁ etc. becomes rounded edges, such as the fine convex portion 100c ₁ by melting, the surface of the heat-reactive part 100c becomes smoother state than before heating (smoothing) for, hardly visually (fine protrusions 100c ₁ And so on, and it is presumed that the light emitted from each of the fine convex portions 100c ₁ does not disperse, and it becomes difficult for a part that looks like a rainbow to appear.

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 The 100 c ₂ and the minute recess 100 c ₂ are in parallel with each other at 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 etc. becomes easy to be seen, the above-mentioned prism action in the fine convex part ₁₀₀ c ₁ etc. becomes more prominent easily, etc. It is guessed that it is doing.

The height H ₁ of the fine convex portion ₁₀₀ c ₁ (FIG. 29) (which corresponds to the depth of the fine concave portion 100 c ₂ in the heat reaction part ₁₀₀ c of the present embodiment) is not particularly limited. However, if the height of the fine convex portion 100c ₁ is too high (the fine concave portion 100c ₂ is too deep), the thermal reaction portion 100c becomes difficult to smooth as described above even if the thermal reaction portion 100c is heated, There is a possibility that the change in appearance of the heat reaction unit 100c may be reduced. For this reason, the height H ₁ of the fine convex portion ₁₀₀ c ₁ is usually 300 μm or less. The height _{H 1} of the fine protrusion 100c ₁ is preferable to be 100μm or less, more preferable to be 50μm or less, more preferable to be 10μm or less is optimal when is 5μm 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.

The arrangement pitch P ₁ of the fine projections ₁₀₀ c ₁ (FIG. 29) (which matches the arrangement pitch of the fine recesses 100 c ₂ in the heat reaction portion ₁₀₀ c of this embodiment) is 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. Arrangement pitch _{P 1} of the fine protrusion 100c ₁ is preferable to be 100μm or less, more preferable to be 50μm or less, more preferable to be 10μm or less is optimal when is 5μm 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 unit 100d is provided at a location different from the location where the heat reaction unit 100c is provided in the cover member 110. The comparison portion 100d is formed by performing the same processing as the heat reaction portion 100c on a portion formed of the same material (the same thermoplastic resin) as the portion forming the heat reaction portion 100c in the cover member 110. There is. That is, if the heat 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 does not necessarily have to coincide with the pattern for providing the heat reaction unit 100c, but the comparison unit 100d of this embodiment, like the heat reaction unit 100c, uses the character string "ABC" It is represented by a graphic pattern. For this reason, the comparison unit 100d before heating is designed to look almost the same as the thermal reaction unit 100c before heating.

  As described above, by providing the comparison unit 100 d at a place other than the place where the heat reaction unit 100 c is provided, the heat reaction unit 100 c is compared with the comparison unit 100 d to change the heat reaction unit 100 c. It becomes easy to notice. That is, it can be easily determined whether the heat reaction unit 100c has been heated. Therefore, even when the whitening mark generated in the whitening portion 100b at the time of fraud release at the time of fraud release is heated and eliminated, it is possible to discover that fact.

The place where the comparison unit 100d is provided is not particularly limited as long as it is a portion formed of the same material as the heat reaction unit 100c in the gaming machine members such as the cover member 110 and the base member 120. In the example of FIG. 22, although the thermal reaction part 100c provided in the fragile part 100b ₁ and the comparison part 100d for comparing with the thermal reaction part 100c are both provided in the same member (cover member 110), The comparison unit 100d may be provided on another member (for example, the base member 120, the protective cover 300, and the like) other than the member provided with the thermal reaction unit 100c to be compared with the comparison unit 100d.

  However, if the comparison unit 100 d is too close to the thermal reaction unit 100 c, the thermal reaction unit 100 b is heated when the tampering whitening unit 100 b is heated for the purpose of erasing the trace of the whitening generated in the tampering whitening unit 100 b. The heat applied to 100c is likely to be applied to the comparison unit 100d as well, and the comparison unit 100d is easily altered in the same manner as the heat reaction unit 100c. For this reason, by comparing the heat reaction part 100c with the comparison part 100d, it becomes difficult to notice the deterioration occurring in the heat reaction part 100c. Therefore, it is preferable that the comparison unit 100d be disposed at a position separated to some extent from the heat reaction unit 100c. Specifically, the comparison unit 100d is preferably provided at a position separated by 5 mm or more from the heat reaction unit 100c, and more preferably provided at a position separated by 10 mm or more.

  On the other hand, when the comparison unit 100d is too far from the heat reaction unit 100c, it becomes difficult to compare the comparison unit 100d with the heat reaction unit 100c. For this reason, it is preferable that the comparison unit 100d be disposed at a position near the thermal reaction unit 100c to a certain extent. Specifically, the comparison unit 100d is preferably provided in a range of a radius of 200 mm from the thermal reaction unit 100d, and more preferably in a range of 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 portion on which a display comprising characters, figures, symbols, colors, or a combination thereof is provided is superimposed on the heat reaction portion 100c. It can also be provided. That is, it is preferable that the identification display unit be disposed so as to overlap the back side (back side) of the heat reaction unit 100c when viewed from a person who checks the heating history of the heat reaction unit 100c. As a result, it is possible to further easily distinguish the apparent deterioration before and after the heating of the heat reaction unit 100c. For example, in the case where the thermal reaction unit 100c is of the above-described heating and erasing type, when the above-described identification display unit is provided, the thermal reaction unit 100c is covered by the thermal reaction unit 100c and is invisible or invisible After heating, the display unit can make the thermal reaction unit 100c appear inconspicuous (transparent or the like) or can be easily seen.

The partition wall portions 126 and 127 are used not only as mere partitions but also as guides for sliding the cover member 110 in the vertical direction with respect to the base member 120 in the above-mentioned assembling procedure 2 and resealing procedure 2 or the like. It has become a functional part.

  As shown in FIG. 31, on the front face side of the rear wall 121 of the base member 120, at the locations that constitute the above-mentioned “A crimped part”, “B crimped part”, “C crimped part” and “F crimped part” Each has an engaging portion 170. The two engaging portions 170 provided on the “A crimped portion” of the base member 120 are attached to the “A crimped portion” of the cover member 120 during “A crimped” in which the cover member 110 is assembled to the base member 120. It becomes a part for pushing in and engaging with the provided engaged portion 130 (FIG. 23). Further, the engagement portion 170 provided on the “B caulking portion” and the “C caulking portion” of the base member 120 assembles the base member 120 (game board case 100) to the case holder 200 “B caulking” And at the time of "C staking", it is a part for pushing in and engaging with the movable body 220 for engagement provided in the case holder 200 (FIG. 15).

  Furthermore, the engagement portion 170 provided in the “F caulking portion” of the base member 120 is the engaged portion 180 when “F caulking” the cover member 110 and the base member 120 in the above-described return procedure 3. It is a portion for pushing in 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. The engaged portion 180 is separated from the base member 120 at the time of “F caulking” as described in the above-described return procedure 3, and the separated engaged portion 180 is formed of the cover member 110. By fitting the engaged portion insertion port 110b (FIG. 7A) provided at the right end of the upper wall portion 114 from the upper side, the “F crimped portion” of the base member 120 The engaging portion 170 is made engageable. At the time of factory shipment, the engaged portion 180 is connected to the portion around the engaged portion 180 in the base member 120 only through the easily breakable portion such as a fine rib, It can be easily separated.

  In the base member 120, the engaging portion 170 constituting the "A crimped portion", the engaging portion 170 constituting the "B crimped portion", the engaging portion 170 constituting the "C crimped portion", "F crimped" The engaging portions 170 constituting the portion may have different specifications such as dimensions and shapes. However, in this case, the number of parts having different specifications may be increased, 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 the present embodiment, any one of the engaging portions 170 shown in FIGS. 33 and 34 is used, and the specifications of the engaging portions 170 are the same. In addition, as shown in FIG. 31, the pressing direction (z-axis direction) in the “A crimped portion” and the “F crimped portion”, and the pressing direction (x axis direction) in the “B crimped portion” and the “C crimped portion”. In any of the "crimped portions", the fixing surface 171a (FIG. 33) of the engaging portion 170 is fixed to the base member 120 from the front, although it is different. Therefore, it is possible to reduce the manufacturing cost and the like.

In the following, for convenience of explanation, the specific configuration of the engaging portion 170 will be described by taking the case where the engaging portion 170 is used as the “A caulking portion” as an example, and the engaging portion 170 “B caulking portion” Description of the case of using as "C caulking part" etc. is omitted. In the base member 120 of the present embodiment, since the engaging portions 170 such as the “B caulking portion” and the “C caulking portion” have the same form as the engaging portions 170 for the “A caulking portion”, “A The contents described for the engagement portion 170 of the caulking portion also apply to the other engagement portions 170. However, as described above, since the place where the fragile portion 100b ₁ is provided is different between the “A crimped portion” and the “B crimped portion” and the “C crimped portion”, the contents described below are “B crimped When applying to "part" and "C crimped part", it is necessary to reverse "beta ⁺ side" and "beta ^- 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 according to this embodiment has a fixed base 171 for fixing to the base member 120, and an α ⁺ β ⁺ -side engagement provided protruding from the fixed base 171 to the rear side in the pushing direction. engaging portion 172, α ⁺ β ^- side engaging portion 173, α ^- β ⁺ side engaging portion 174 and the alpha ^- beta ^- is composed of a side engaging portion 175. alpha ⁺ beta ⁺ side engaging portion 171 is located in the alpha ⁺ side and beta ⁺ side, alpha ⁺ beta ^- side engaging portion 172, alpha ⁺ side and beta ^- located on the side, alpha ^- 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 pressed in the engaging portion 170. It consists of a rod-like protrusion arranged substantially in 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 There is. 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 It is engaged portion 130 so as to be engaged with the alpha ⁺ side the engaging wall portion 131 (FIG. 24), provided in a state protruding alpha ⁺ side, alpha ^- side alpha ^- beta ⁺ side engagement The hook portions of the joint portion 174 and the α ^- β ^- side engagement portion 175 (hereinafter, may be referred to as “α ^- side engagement portions 174 and 175”) are engaged portions 130 (FIG. 24). ) of alpha ^- so as to be engaged with the side to be engaging wall portion 132, alpha ^- is provided in a state protruding to the side.

The push direction back side of the hook portion of the α ⁺ -side engaging portion 172, 173 and the back side of the push direction of the hook portion of the α ^- side engaging portion 174, 175 become the pushing direction back side It is formed in the inclined state so that it may mutually approach. Therefore, when pushing the engaging portion 170 into the engaged portion 130, the surface on the back side in the pushing direction of the hook portions of the α ⁺ -side engaging portions 172 and 173 is the surface of 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 to the α ⁺ side. That is, when the engaging portion 170 is pushed into and engaged with the engaged portion 170, 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 in directions approaching each other in the α direction.

Further, as described above, the engaging portion abutted surface 140a of the pressing displacement regulating portion 140 and the engaging portion abutted surface 150a of the proximity displacement regulating portion 150 approach each other as they become farther in the pushing direction. It is inclined to Therefore, when pushing the engaging portion 170 in the engaged portion 130, beta ⁺ side of alpha ⁺ beta ⁺ side engaging portion 172 and the alpha ^- beta ⁺ side engaging portion 174 (hereafter "beta ⁺ and it may be referred to as the side engaging portions 172, 174 "), beta ^-. side alpha ⁺ beta ^- side engaging portion 173 and the alpha ^- beta ^- side engaging portion 175 (hereafter" beta ^- side The engaging portions 173 and 175 "may be elastically displaced in directions approaching each other also in the β direction as shown by a broken line in FIG.

Thus, the engagement portion 170 of this embodiment is configured to be elastically displaced in both the α direction and the β direction when performing the engagement. For this reason, when trying to release the engagement by the engaging portion 170 improperly, the α ⁺ -side engaging portions 172, 173 and the α ^-- side engaging portions 172, 173 are brought closer to 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 toward each other in the β direction. Is required. In addition, in the present embodiment, when the engaging portion 170 is engaged with the engaged portion 130, the pushing displacement restricting portion 140 (FIG. 24) is formed in 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 more difficult.

Therefore, it is difficult for the engagement portion 170 to unfairly release the engagement without leaving a trace such as whitening on it. In particular, the base end 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 be concentrated), and is a portion that is easy to use 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 the whitening unit), for the same reason as the heat-reactive part 100c provided above the fragile portion 100b 1 _(FIG. 22), may be provided heat-reactive part 100c that appearance altered when heated.

In this case, all base end portions 100 b _{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. The thermal reaction unit may be provided on the front side of the gaming machine substrate case 100, and it is effective to provide the thermal reaction unit on a portion that is easily visible from the front side of the gaming machine substrate case 100. In the engaging portion 170 (the engaging portion 170 of the “A crimped portion”) of the present embodiment, the α ⁺ β ⁻ side engaging portion 173 and the α ⁻ β ⁻ side engaging portion in 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 gaming machine substrate case 100 . For this reason, as shown in FIG. 33, in the engaging portion 170 of the present embodiment, the thermal reaction portion 100c is provided on the surface of the base end portion of the α ⁺ β ⁻ side engaging portion 173 facing forward. 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 heat reaction part 100c in the engaging part 170, it is also possible to employ | adopt the following structures. FIG. 36 is an oblique view of the engaging portion 170 of another embodiment. In the engaging portion 170 of FIG. 33, all 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 However, in the engagement portion 170 of FIG. 36, the α ⁺ β ⁻ side engagement portion is easily visible from the front side of the gaming machine substrate case 100, although it extends substantially linearly 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, alpha ⁺ beta ^- side engaging portion 173 and the alpha ^- beta ^- proximal end 100b ₂ side engaging portion 175, unauthorized release plastic deformation is particularly prone part of the whitening and the like when the (illegal cancellation whitening It is a preferable part by utilization as the part 100b.

Further, the engagement portion 170 of FIG. 33, alpha ⁺ beta ^- had a heat-reactive part 100c provided only on the side engaging portion 173 proximal end portion. In addition, in the engaging portion 170 of FIG. 33, the thermal reaction portion 100c is provided in a pattern in which characters are illustrated. 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 even more difficult to erase the trace of the heat reaction without damaging the thermal reaction part 100c.

  The way of providing the engaging portion 170 to the base member 120 is not particularly limited. In the base member 120 of the present embodiment, an engaging portion 170 which is a separate member from the base member 120 is fixed at a predetermined position on the base member 120 afterward. The method for fixing the engaging portion 170 to the base member 120 is not particularly limited, but in the base member 120 of the present embodiment, the fixing surface 171a of the fixed base 171 of the engaging portion 170 is vibration welded to the target location 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 Plastic deformation such as whitening occurs in the fragile portion 100b ₁ (whitening portion 100c at the time of fraud release) when the engaging portion 170 is illegally pulled out from the engaged portion 130 (in the case of fraud release) 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 beta ⁺ side engaging portion 172 and 174 (only alpha ⁺ beta ⁺ side engaging portion 172 in the figure are drawn.)

The movable part for engagement 220 used as the engaged part of the "B caulking part" and the "C caulking part" is the same as the engaged part 130 used as the "A caulking part". It has a structure.

FIG. 42 is a view of the engaged movable body 220 from the front upper right corner. FIG. 43 is a six-sided view of the to-be-engaged movable body 220 in FIG. 42, with the surface on the negative side in the x-axis direction in the same drawing as the front. As shown in FIG. 42, the movable movable body 220 according to this embodiment has an α ⁺ -side engaged wall portion 221 located on the α ⁺ -side (z-axis direction negative side), and an α ⁻ -side And an α ^- side engaged wall portion 222 located on the positive side). 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 corresponds to the engaged portion 130. It corresponds to the α ^- side engaged wall 132 in FIG. The movable body 220 for engagement corresponds to a connecting wall 223 corresponding to the connecting wall 133 of the engaged portion 130 (FIG. 24) and a bottom wall 134 for the engaged portion 130 (FIG. 24). The connecting wall portion 224 is also provided. For this reason, the movable body 220 for engagement has a frame shape in a front view (see the front view in FIG. 42) as in the engaged portion 130, and is in a state in which the rigidity is enhanced.

  Further, in the engaged portion 130 of the “A crimped portion”, as shown in FIG. 24, the push-in displacement restricting portion 140 is provided on the connection wall portion 133, and the proximity displacement restricting portion 150 is provided on the bottom wall portion 134. On the other hand, in the movable body 220 for engagement, as shown in FIG. 43, the proximity displacement restricting portion 230 having the same function as the proximity displacement restricting portion 150 is provided on both the connection wall 223 and the connection wall 224. (A portion having the same function as that of the push-in displacement restricting portion 140 is not provided on the engaged movable body 220.) The configuration described in the proximity displacement regulating unit 150 can also be adopted in the pressing displacement regulating unit 230. Therefore, the detailed description of the proximity displacement control unit 230 is omitted.

Furthermore, in the "A caulking portion", as shown in FIG. 13, beta ⁺ (in the figure are drawn only alpha ⁺ beta ⁺ side engaging portion 172.) Side engaging portion 172 engaging surface 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 When the engaging portion 170 engaged with the engaged portion 130 is to be pulled out from the engaged portion 130, the β ^- side engaging portions 173 and 175 close to the fragile portion 100b ₁ are Before the engaging surface 170a of the engaging portion 130 abuts on the engaging surface 130a of the engaged portion 130, the engaging surfaces 170a of the .beta..sup. ⁺ Side engaging portions 172 and 174 far from the fragile portion 100b ₁ are engaged Although the device was made to abut on the engaged surface 130a of 130, "B crimped portion" and "C crimped portion" However, the same device as this 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 The above-described effect is obtained in a manner different from that of the “A-crimped portion”.

That is, in the “A crimped portion”, as shown in FIG. 13, in the engaging portion 170, the side (positive side in the y-axis direction) closer to the fixing surface 171a of the fixed base 171 is the β ⁺ side (the side farther from the fragile portion) The side (the y-axis direction negative side) far from the fixed surface 171a of the fixed base 171 is the β ⁻ side (the side closer to the fragile portion 100b ₁ ). On the other hand, in the "B crimped portion" and the "C crimped portion", as shown in FIG. 18, the side closer to the fixing surface 171a of the fixed base 171 (y axis direction positive side) is β ^The negative side (closer to the fragile portion) and the side (y-axis direction negative side) farther from the fixed surface 171a of the fixed base 171 is the β ⁺ side (the remote side 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 When the) is used as it is in the "B crimped portion" and the "C crimped portion", the state shown in FIG. 44 is obtained. FIG. 44 shows an engagement portion with respect to an engaged portion (a movable object 220 for engaged surface in which the engaged surface 220a is flat) in which the case holder 200 is provided as a “B crimped portion” or a “C crimped portion” It is the figure which looked at the state which engaged 170 from the downward direction. (Beta) ⁺ side engagement parts 172 and 174 (only the (alpha) ⁺ beta ⁺ side engagement part 172 is drawn in the same figure) in the engagement part 170 of FIG. 44 and the beta ^- side engagement parts 173 and 175 (the same FIG the alpha ⁺ beta ^-. depicted only side engaging portion 173) is, for the reasons already mentioned, the engagement portion 170 of FIG. 13 beta ⁺ side engaging portions 172, 174 and beta ^- side engagement Parts 173 and 175 are reversed.

Therefore, from the state shown in FIG. 44, the engaging portion 170 when an attempt is made to pull out from the engaged movable member 220 is closer to the fragile portion 100b ₁ (bad cancellation whitened portion 100b) beta ^- side engaging portion 173, After the engagement surface 170a of 175 abuts on the engagement surface 220a of the engagement movable body 220, the engagement surfaces 170a of the β ⁺ -side engagement portions 172 and 174 which are far from the fragile portion 100b ₁ It comes in contact with the engaged surface 220a of the movable body 220 for alignment. Therefore, the above-described effect obtained by the “A crimped portion” can not be obtained by the “B crimped portion” and the “C crimped portion”.

For this reason, in the present embodiment, as shown in FIG. 18, the engagement of the engagement portion 170 with the engagement surface 220a of the movable engagement object 220 constituting the “B crimped portion” and the “C crimped portion”. It is provided with a step S ₂ over the step S ₁ in mating surface. As a result, even when parts having the same form as the engaging portions 170 of the “A crimped portion” are used as the engaging portions 170 of the “B crimped portion” and the “C crimped portion”, the fragile portion ₁₀₀ b ₁ The β ⁺ side far from the fragile portion 100b ₁ before the engagement surface 170a of the β ⁻ side engagement portions 173 and 175 close to the whitening portion 100b abuts on the engagement surface 220a of the movable body for engagement 220 The engagement surface 170 a of the engagement portions 172 and 174 abuts on the engagement surface 220 a of the movable engagement object 220. Therefore, also in the "B crimped portion" and the "C crimped portion", similarly to the "A crimped portion", when the engaging portion 170 is illegally pulled out from the engaged movable body 220 (during fraudulent 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 engagement surface 220 a of the movable body 220 for engagement is not particularly limited as long as it is larger than the step S ₁ (FIG. 13) on the engagement surface 170 a of the engagement 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-described effects may not be achieved. Therefore, the difference _S 2 -S ₁ is usually a 0.1mm 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-like held portion 225 is provided on the back side in the pushing direction of the movable body for engagement 220. The held portion 225 is a portion for being held in a state of being fitted into the internal space of the movable body holding portion 210, as shown in FIG.

It is wider than the direction of the width W _2.

  For this reason, the movable body for engagement 220 held by the movable body holding portion 210 can not be removed from the movable body holding portion 210 unless the movable body holding portion 210 is broken or the like. In other words, the movable body 220 for engagement is removed from the other portion (the main body of the case holder 200) in the case holder 200, and can not be carried independently from the main body. Therefore, it is also possible to prevent fraudulent acts such as exchanging the engaged movable body 220 with a forged product that can be easily released.

  Further, as shown in FIG. 42, the engagement movable body 220 is provided with a positioning fitting portion 220b. The positioning fitting portion 220 b is a portion for positioning the movable body for engagement 220 with respect to the movable body holding portion 210. That is, as shown in FIG. 41, when the movable body for engagement 220 is at the first position, the positioning fitting portion 220b is engaged with the first position for mating portion 210b of the movable body holding portion 210. When the to-be-engaged movable body 220 is at the second position, it is fitted to the second position to-be-fitted portion 210 c of the moving body holding portion 210.
