<7. Mounting / sealing procedure and subsequent opening procedure>
When the main board case 43 as described above is mounted on a gaming machine, first, the main board case 43 is sealed in a state where the main control board 13 is stored, and an IC tag seal 45 is attached to the main board case 43. A procedure is performed in which the seal cover 50 is attached and the main board case 43 in that state is attached and sealed to the attachment base 36 fixed in advance in the casing of the gaming machine. Hereinafter, the mounting / sealing procedure and the subsequent opening procedure will be briefly described with reference to FIGS.

(7-A1. Attaching the Main Control Board 13 to the Main Board Case 43)
First, the main control board 13 is mounted on the main board case 43. As a previous step, the back case body 41, the front case body 42, and the closing sealing member 47 are connected to each other by the connecting member 52.

  In addition, with the mounting sealing member 48 inserted into the second back case side sealing mounting portion 74a, the back case body 41 and the front case body 42 are fitted together and slid to each other to be in a closed locked state, thereby closing the sealing If the member 47 is mounted on the sealing member holder 93 and the back case body 41 and the front case body 42 are connected, the unsealed main substrate case 43 can be easily transported as a unit. At this time, the mounting sealing member 48 is stored in the second sealing mounting portion 74, and the closing sealing member 47 is connected to the main board case 43 by the connecting member 52. There is no worry about losing.

  When the main control board 13 is mounted, the back case body 41 and the front case body 42 of the main board case 43 temporarily assembled in an unsealed state as described above are slid to the mounting unlocked state side. The main control board 13 is mounted inside the front case body 42.

(7-A2. Closing / sealing of main board case 43)
The front case body 42 to which the main control board 13 is mounted is closed by fitting from the front side to the back case body 41 in a state where the mounting sealing member 48 is inserted into the second back case side sealing mounting portion 74a. An unlocked state is set (FIG. 5A).

  At this time, the first and second back case side sealing mounting portions 73a and 74a on the back case body 41 side and the first and second front case side sealing mounting portions 73b and 74b on the front case body 42 side are mutually The shaft is shifted in the closing slide direction.

  Subsequently, the front case body 42 is slid rightward with respect to the back case body 41. As a result, in FIG. 2, the closing engagement means 54 on the back case body 41 side engages with the engaged portion 55b on the front case body 42 side, and the main board case 43 enters a closed lock state. Further, the first and second back case side sealing mounting portions 73a and 74a on the back case body 41 side and the first and second front case side sealing mounting portions 73b and 74b on the front case body 42 side are closed in the sliding direction. It becomes a state which mutually matched in the front-back direction orthogonal to (FIG.5 (b)).

  At this time, as can be seen from FIG. 7, the holding rib 129 on the second front case side sealing mounting portion 74b side is the rear end side in the insertion direction of the mounting sealing member 48 in the second back case side sealing mounting portion 74a. Therefore, the mounting sealing member 48 is fixed in a state in which the protruding portion 128 on the tip side protrudes from the through hole 78 to the back side.

  Subsequently, the closure sealing member 47 is detached from the sealing member holder 93 and inserted into the first seal mounting portion 73, and the retaining engagement claw 123 is attached to the back side end portion of the first front case side seal mounting portion 73b. It is set as the state (refer FIG. 7) engaged (FIG.5 (c)). As a result, the first back case side sealing mounting portion 73a and the first front case side sealing mounting portion 73b cannot be moved relative to each other in the closing slide direction. Therefore, the back case body 41 and the front case body 42 are closed. Regulated in the locked state. Moreover, since the retaining engagement claw 123 is covered with the first back case side sealing mounting portion 73a (see FIG. 7), the engagement of the retaining engagement claw 123 is released from the outside to be closed and sealed. The member 47 cannot be removed, and therefore the main board case 43 is in a closed sealing state in which sliding toward the closed unlocked state is prevented from being unreleasable.

(7-A3. Attaching the IC tag seal 45 and attaching the seal cover 50)
Subsequently, the IC tag seal 45 is pasted on the IC tag seal pasting surface 82, the seal cover 50 is overlaid so as to cover the surface of the IC tag seal 45, and the coupling pin 143 is inserted into the coupled portion 112 as shown in FIG. Install by passing through the slit.

  Here, for example, a plurality of main board cases 43 sealed as described above are prepared, and the seal cover 50, the back case body 41, and the front case body 42 without any trace of opening from the main board cases 43 are prepared. Even if the closing sealing member 47 and the like are successfully taken out, the back case body 41, the front case body 42 and the closing sealing member 47 are connected to the connecting member 52 (the first connecting band portion 49a and the second connecting band portion 49b). ), It is necessary to cut the connecting member 52 in order to create a new main board case 43 by combining them. That is, even if a new main board case 43 is created by combining the back case body 41, the front case body 42, the closing sealing member 47, etc. taken out from the plurality of main board cases 43, the state is still connected by the connecting member 52. Can not be reproduced, and such fraud can be effectively prevented.

(7-A4. Mounting / sealing of main board case 43 to mounting base 36)
Next, the main board case 43 in a closed and sealed state is fitted from the front side to the mounting base 36 fixed in advance to the gaming machine, and the mounting engaging means 57 on the mounting base 36 side is mounted on the mounting guide groove on the front case body 42 side. Each of the fitting portions 58a in 104 is fitted into an unlocked state and temporarily fixed by upper and lower temporary fixing hooks 155 and 156. In this mounted unlocked state, the protrusion 165 on the back side of the main board case 43 shown in FIG. 3 is engaged with the right side of the slide restricting part 164 on the mounting base 36 side. It cannot be slid to the wearing lock side (left side).

  Subsequently, the temporary fixing hook 156 is elastically deformed to temporarily release the engagement with the positioning rib 166, and then the main board case 43 is slid rightward with respect to the mounting base 36 (FIG. 6A). (B)). As a result, the mounting engagement means 57 on the mounting base 36 side shown in FIG. 1 engages with the mounting engaged means 58 on the front case body 42 side, and the main board case 43 is locked to the mounting base 36 in the first mounting lock. It becomes a state. At this time, as shown in FIG. 6B, the protrusion 128 on the main board case 43 side engages with the first mounting sealing engagement claw 157, and the sliding toward the mounting unlocked state is restricted. In addition, the engagement of the first mounting sealing engagement claw 157 cannot be released from the outside, and therefore, the main board case 43 is prevented from sliding to the mounting unlocked state with respect to the mounting base 36. The attached sealed state is obtained.

  The connector cover 46 may be attached after the main board case 43 is attached to the mounting base 36 and the harness side connector 105 is connected to the connector 61a on the main board case 43 side.

(7-B1. Removal of Main Board Case 43)
When the main board case 43 mounted in the pachinko gaming machine is opened for inspection or the like by the above procedure, the connector cover 46 is first removed and the harness side connector 105 is removed from the connector 61a. Then, using a tool such as a screwdriver, the closure lid 110 is pierced, the closure lid 110 is removed to open the end of the second sealing mounting portion 74, and the mounting sealing member 48 is extracted therefrom (FIG. 8). . As a result, the protrusion 128 that has been engaged with the first attachment sealing engagement claw 157 disappears, and the attachment sealing state is released. Therefore, the temporary fixing hook 156 is elastically deformed to engage with the positioning rib 166. Can be removed from the mounting base 36 by sliding the main board case 43 toward the mounting unlocked state with respect to the mounting base 36.

(7-B2. Removal of seal cover 50 and cutting of IC tag seal 45)
Subsequently, the seal cover 50 is removed from the main board case 43 removed from the mounting base 36, and the IC tag seal 45 is cut with a cutter knife or the like. Thereby, the main substrate case 43 is released from the sealed state by the seal cover 50 and the sealed state by the IC tag seal 45.

(7-B3. Opening of main board case 43)
Subsequently, the second connecting band portion 49b of the connecting member 52 is cut to release the connection between the main board case 43 and the closing sealing member 47, and then the connecting rib 108a of the first front case side sealing mounting portion 73b. -108d are cut using a cutting tool such as a nipper, and the first front case side sealing mounting portion 73b is removed from the front case body 42 together with the closing sealing member 47 (FIGS. 9A and 9B). Thereby, since the closed sealing state of the main substrate case 43 is released, the main substrate case 43 can be opened by sliding the back case body 41 toward the closed unlocked state with respect to the front case body 42. .

(7-C1.2 Main Board Case 43 Sealing)
In the main substrate case unit 14 of the present embodiment, once opened, the sealing can be performed again with the trace left. Hereinafter, the second sealing and opening procedure will be briefly described. Since the seal cover 50 is broken at the first opening, it cannot be mounted again at the second sealing. Further, the mounting sealing member 48 is not used for the second sealing.

  First, as in the first sealing, the front case body 42 is fitted to the back case body 41 from the front side to be in a closed unlocked state, and then the front case body 42 is attached to the back case body 41. Slide it to the right to lock it. At this time, the mounting sealing member 48 is not inserted into the second back case side sealing mounting portion 74a.

  Subsequently, the closing sealing member 47 separated from the front case body 42 at the first opening is inserted into the second sealing mounting portion 74 instead of the first sealing mounting portion 73 this time (FIG. 10). The second front case side sealing mounting portion 74b constituting the second sealing mounting portion 74 can be inserted with the closing sealing member 47 by removing the closing lid 110 (see FIG. 8) at the first opening. It is in a state. As a result, the second back case side sealing mounting portion 74a and the second front case side sealing mounting portion 74b cannot be moved relative to each other in the closing slide direction. Therefore, the back case body 41 and the front case body 42 are closed. Regulated in the locked state. Moreover, since the retaining engagement claw 123 is covered with the second back case side sealing mounting portion 74a, the engagement of the retaining engagement claw 123 is released from the outside and the closing sealing member 47 is removed. Therefore, the main board case 43 is in a closed sealed state in which sliding to the closed unlocked state is prevented from being unreleasable.

(7-C2.2 Mounting / Sealing of Main Board Case 43 to Mounting Base 36)
Next, after removing the projection 165 (FIG. 3) on the back side of the main board case 43 with a nipper or the like, the main board case 43 is fitted into the mounting base 36 to be in an unlocked state, and temporarily fixed by the upper and lower temporary fixing hooks 155 and 156. Fix it. Then, the main board case 43 is slid with respect to the mounting base 36 in the second mounting lock state side, that is, leftward opposite to the first time. At this time, since the protrusion 165 corresponding to the slide restricting portion 164 has already been removed, the slide to the second mounting lock state side is not restricted.

  As a result, the engagement protrusion 80 (FIG. 3) on the main board case 43 side engages with the second attachment sealing engagement claw 158, and the sliding toward the attachment unlocked state is restricted (FIG. 11). In addition, the engagement of the second mounting sealing engagement claw 158 cannot be released from the outside, and therefore the main board case 43 is prevented from sliding to the mounting unlocked state with respect to the mounting base 36 so as not to be released. The attached sealed state is obtained.

(7-D1.2 main board case 43 removal)
When removing the main board case 43 mounted as described above, first the opening lid 79 (FIG. 3) is pierced by using a tool such as a screwdriver in the first sealing mounting portion 73, and the opening lid 79 is removed. Thus, an opening 81 is formed (FIG. 12). Then, the second mounting sealing engagement claw 158 is pressed through the opening 81 to release the engagement with the engagement protrusion 80, and the main board case 43 is slid toward the mounting unlock state with respect to the mounting base 36. It is possible to remove from the mounting base 36.

(7-D2.2 opening of the main board case 43)
Subsequently, the connecting ribs 108c to 108d and 107 of the second front case side sealing mounting portion 74b are cut using a cutting tool such as a nipper, and the second front case side sealing mounting portion 74b is closed with the closing sealing member 47. At the same time, it is removed from the front case body 42 (FIG. 13). Thereby, since the closed sealing state of the main substrate case 43 is released, the main substrate case 43 can be opened by sliding the back case body 41 toward the closed unlocked state with respect to the front case body 42. .

<8. Structure of connecting rib 107>
Here, fraudulent acts that may be performed in connection with the cutting of the connecting rib will be described.

  FIG. 14 shows the process of taking out the first front case side sealing mounting portion 73b in the first sealing mounting portion 73. FIG. 14A shows the connecting ribs 108a to 108d of the first front case side sealing mounting portion 73b. The figure which showed a mode that it cut | disconnects using cutting tools, such as a nipper, (b) is the figure which showed the space part 73c after removing the 1st front case side sealing mounting part 73b from the front case body 42 And (c) is a view showing the removed first front case side sealing mounting portion 73b.

  In such a normal removal operation, it is preferable that the operation of cutting using a cutting tool such as a nipper is easy. For this reason, the connecting ribs 108a to 108d are formed in a plate shape having a rectangular cross section. That is, when the connecting ribs 108a to 108d are cut with a cutting tool such as a nipper, the trace of the cutting always remains, so only the ease of cutting work is regarded as important, and the possibility of fraud has not been considered. .

  However, for the second sealing mounting portion 74, suppose that both sides of the second front case side sealing mounting portion 74b are supported by plate-like connecting ribs 108a to 108d having the same rectangular cross section as the first front case side sealing mounting portion 73b. In this case, the connecting ribs 108a to 108d of the second front case side sealing mounting portion 74b are cut into a beautiful cut using a special cutting tool, and the second front case side sealing mounting portion 74b is closed and sealed. After removing from the front case body 42 together with the stop member 47 (FIG. 13), the second front case side sealing mounting portion 74b is returned to its original position, and the cut portion is traced using a transparent adhesive. There was a report of a possible fraudulent act of connecting so as not to remain.

  Therefore, in this embodiment, as shown in FIG. 15, on one side of the second front case side sealing mounting portion 74b, two connecting ribs 108c to 108d having a plate shape with a rectangular cross section are attached to the sealing support frame 109. The other one side is configured such that one connecting rib 107 having a fragile surface 107a is hung over the space between the sealing support frame 109 and the other side. Here, the linking rib having a fragile surface refers to a linking rib having a special shape having a fragility in which the shape of the surface changes when the linking rib is cut.

  As such a fragile special shape, the connecting rib 107 in this embodiment has a triangular shape when the upper surface 107a serving as the outer surface is viewed in the direction along the side of the second front case side sealing mounting portion 74b. It is formed in a shape (triangular wave shape) in which the protrusions of the cross section are continuous. Further, as can be seen from FIG. 16, the connecting rib 107 is formed in a gate shape as a whole when viewed from the second front case side sealing mounting portion 74b side, and the upper side portion 105 having the fragile surface 107a and both sides thereof. And side portions 106 for reinforcement. The length W of the upper side portion 105, that is, the length W in the direction along the side where the connecting rib 107 of the second front case side sealing mounting portion 74b is located corresponds to the width of the connecting rib 107, The width W of the connecting rib 107 is substantially equal to the length L of the side of the second front case side sealing mounting portion 74b. Therefore, the connecting rib 107 is configured as one wide connecting rib. Since the side portions 106 are positioned at both ends of the connecting rib 107 in the cutting direction (arrow Y direction in FIG. 16), the outer surface of the side portions 106 at both ends is one side of the second front case side sealing mounting portion 74b. Are separated by a distance corresponding to both ends. This separation distance is the same as the distance between the outer surfaces of the connecting ribs 108a and 108b of the first back case side sealing mounting portion 73a. That is, the connecting rib 107 has a shape in which the side portions 106 and 106 having the same configuration as the connecting ribs 108 a and 108 b are connected by the upper side portion 105.

  As shown in FIG. 17, the connecting rib 107 is formed so that the side portions 106 on both sides thereof are formed with the same thickness t1 as the connecting ribs 108 c to 108 d and the same height H, and connects the upper ends of the side portions 106. The upper side 105 is provided. Here, the upper side portion 105 is formed to have a thickness t2 that is substantially the same as or slightly smaller than the thickness t1 of the side portions 106. The upper surface of the upper side portion 105, that is, the ridge having a triangular cross section that imparts brittleness to the outer surface of the connecting rib 107 is the direction along the side of the second front case side sealing mounting portion 74b, that is, the cutting direction (see FIG. A suitable number of triangles are formed in a predetermined pitch P and depth d in the direction of 16 arrows Y). In this embodiment, ten triangular cross-section ridges are provided so that the triangles in the cross-section are continuous at a depth that does not reach the wall thickness t2, whereby the upper surface is formed as a fragile surface 107a.

<9. Action of connecting rib 107>
When the connecting rib 107 is configured as described above, the following operational effects can be obtained. When cutting the connecting rib 107, the connecting rib 107 is cut as shown by an arrow Y in FIG. Since this cutting cuts the fragile surface 107a in the direction in which the protrusions of the triangular cross section are continuous, a series of triangular protrusions must be cut one after another. As a result, the tip of the protrusion of the triangular cross section is chipped small at the time of cutting, and the triangular protrusion is damaged, and the continuity of the triangular waveform is lost, and the cut end cannot be cut cleanly.

  Therefore, even if the connecting rib 107 is cut and the main substrate case 43 is illegally opened, a transparent adhesive is applied to the cut ends and the cut ends of the connecting ribs 107 are connected to each other. Remarks of cutting remain noticeably on the surface 107a, and the connection location is immediately visible with the naked eye from the outside, and it becomes possible to detect fraud. For this reason, by forming a number of protrusions, such as protrusions having a triangular cross-section, on the upper surface of the connecting rib 107 and imparting brittleness, no trace of cutting remains in the cut portion using a transparent adhesive. It is possible to prevent an illegal act of connecting to the network.

<10. Modification>
In the above embodiment, the shape of the protrusion forming the brittle surface 107a of the connecting rib 107 is a triangular corrugated shape, but at least the outer surface of the connecting rib 107 (the upper surface along the plane of FIG. 17). The cross-sectional shape can be imparted with a weakness in the sawtooth cross-sectional waveform, for example, as shown in FIG. 18 (a). Or a fragile surface 107a having a wavy cross-sectional waveform with continuous wavy projections as shown in FIG. 18B.

  Further, the ridges having a cross-sectional shape such as a triangular shape, a sawtooth shape, and a wave shape that impart these weaknesses need to always exist continuously over the entire cutting direction (Y direction) of the connecting rib 107. As shown in FIGS. 19 (a) to 19 (c), continuity is partially lost by thinning out some of the tooth shapes (projections) constituting the triangular waveform, sawtooth waveform, or wavy waveform. The brittle surface 107a can also be in the form of a broken shape, that is, a shape in which triangles, sawtooth, and wave shapes are intermittently arranged.

  Further, in the form in which the upper surface of the connecting rib 107 is a fragile surface 107a having a sawtooth waveform, as shown in FIG. 19 (d), the direction of the sawtooth waveform is halfway as viewed in the cutting direction (Y direction). It can also be set as the form changed into the reverse direction from. Further, also in this embodiment, as shown in FIG. 19 (e), the continuity is partially lost by thinning a part of the sawtooth ridge from the sawtooth waveform, that is, a triangle, a sawtooth shape, and a waveform. It can be set as the form which arrange | positioned this protrusion intermittently.

  In the embodiment described above, the connection rib 107 is viewed from the side of the second front case side sealing mounting portion 74b, and the entire shape of the connection rib 107 is configured in a gate shape (see FIG. 16), but as shown in FIG. (A) M-shape with the center lowered linearly, (b) Concave shape with the center lowered in an arc shape, (c) Roof shape with the center raised linearly, (d) Center shape in an arc shape It can be configured as a raised convex shape.

  Further, in the above-described embodiment, the description has been given of the form in which the protrusions of the triangular cross section extend long in the direction orthogonal to the cutting direction (Y direction), but the triangular cross-section protrusions or the sawtooth shape constituting the fragile surface 107a. The corrugated protrusions and the corrugated protrusions do not necessarily have to extend long in a direction perpendicular to the cutting direction (Y direction), but are staggered as a large number of protrusions on the upper surface of the connecting rib 107 or They may be arranged randomly. Therefore, these many protrusions can also be arranged so as to draw characters, symbols, and the like with the protrusions.

  Further, the main reason for providing both side portions 106 on the connecting rib 107 is to reinforce the upper side portion 105 that has been made brittle on the upper surface 107 a by a triangular waveform or the like. Is not necessarily provided at right angles, and for example, as shown in FIG. 20 (e), the entire connecting rib 107 may be provided in a trapezoidal shape. Further, depending on circumstances, one of the side portions 106 may be omitted, or both the side portions 106 may be omitted, and the connecting rib 107 may be configured with only the upper side portion 105.

  Moreover, in the said embodiment, although it supported by the wide connection rib 107 which has the weak surface 107a only about one side of the 2nd front case side sealing mounting part 74b, the wide which has the weak surface 107a about both sides. These connecting ribs 107 can also be supported.

  Moreover, in the said embodiment, although the one connection rib 107 was arrange | positioned and supported about one side of the 2nd front case side sealing mounting part 74b, the connection rib with a weak surface is 2 with respect to one side. The second front case side sealing mounting portion 74b can also be supported by arranging as described above.

  Moreover, in the said embodiment, although the connection rib 107 with a weak surface was provided only in the 2nd front case side sealing mounting part 74b, the connecting ribs 108c-108d and 108a- of the 1st front case side sealing mounting part 73b were provided. Instead of 108b, a connecting rib 107 with a fragile surface 107a can be provided.

  In the above-described embodiment, the connecting rib 107 is configured such that the side portions 106 and 106 are connected to each other in a gate shape or the like at the upper side portion 105, but each side portion 106 that is independent without being connected at the upper side portion 105. As shown in FIG. 21, a fragile surface 107a can be formed on the top surface (that is, the outer surface) or the side surface. In FIG. 21, (a) is an example in which a ridge having a triangular cross section is provided on the top of the side part 106 to form the fragile surface 107a, and (b) is the thickness of the side part 106 on the top of the side part 106. An example in which the fragile surface 107a is formed by providing a triangular cross-section with some flat portions on both sides in the direction, (c) is slightly on both sides in the thickness direction of the side portion 106 on the top of the side portion 106. This is an example in which the brittle surface 107a is formed by providing a trapezoidal cross-section ridge leaving the flat portion. Further, (d) forms a fragile surface 107a by providing a triangular cross-section ridge on the top of the side portion 106, and also provides a fragile surface 107a by providing a triangular cross-section ridge on the side of the side portion 106. This is an example of formation.
