Then, the cover portion 112 may be separated from the base portion 111 in the direction perpendicular to the electronic substrate 300.

Further, on one end surface of the base portion 111, a base portion rotating shaft 117 that is rotatably supported by the case holder 200 is provided. The structure in which the base rotation shaft 117 is supported by the case holder 200 will be described later. Further, a caulking pin insertion portion 119 into which the caulking pin 400 is inserted is provided on the other end surface of the base portion 111. The caulking pin insertion portion 119 has an insertion hole 102 (see FIG. 15), which is a through hole into which the caulking pin 400 is inserted, and has a substantially cylindrical shape. The caulking pin insertion portion 119 is rotatably mounted on the shaft mounting portion 201 (see FIG. 7) of the case holder 200. Further, a screwing portion 140 screwed to the case holder 200 is rotatably connected to the caulking pin insertion portion 119 with respect to the caulking pin insertion portion 119. Specifically, the screwing portion 140 is integrated with the ring 141, and this ring 141 is difficult to remove on the outer circumference of the caulking pin insertion portion 119, and can rotate around the caulking pin insertion portion 119 as a rotation axis. It will be fitted like this. As a result, the screwing portion 140 integrated with the ring 141 is rotatably connected to the caulking pin insertion portion 119.

Further, at the end of the cover portion 112, a notch 118 is formed at a position corresponding to the caulking pin insertion portion 119 in a state where the base portion 111 and the cover portion 112 are combined. As described above, when the caulking pin 400 is inserted into the caulking pin insertion portion 119, the caulking pin 400 penetrates the base portion 111 and reaches the notch 118. In this way, the caulking pin 400 penetrates the base portion 111 and is caught in the notch 118 of the cover portion 112, so that it is difficult to slide the cover portion 112 with respect to the base portion 111 in the direction along the base portion 111. Become. Therefore, it is difficult to separate the cover portion 112 from the base portion 111 when the caulking pin 400 is inserted into the caulking pin insertion portion 119.

Specifically, first, the four corners of the electronic substrate 113 are fixed to the cover portion 112 with screws 120c to 120f. Next, the base portion 111 is fixed to the cover portion 112 to which the electronic board 113 is fixed by the screws 120a and 120b. As a result, the board case main body 110 is configured.

Although the configuration of the board case main body 110 has been described above, the protective cover 130 can be attached to the board case main body 110. Although the details will be described later, the protective cover 130 not only covers and protects the connectors 116a to 116c exposed to the outside from the board case main body 110, but also the board case 100 for a gaming machine attached to the case holder 200 is a case. It is intended to prevent the holder 200 from coming off. The protective cover 130 is attached to the board case main body 110 after the board case main body 110 is attached to the case holder 200.

(Explanation of the mounting structure of the board case body)
When the board case main body 110 is attached to the housing main body 10a, the board case main body 110 is attached to the case holder 200 arranged on the back plate inside the housing main body 10a as described above. The back plate of the housing body 10a is arranged parallel to the xy plane, and the case holder 200 is also arranged parallel to the xy plane. The board case main body 110 is attached to the case holder 200 arranged in the housing main body 10a in this way.

The mounting structure of the substrate case main body 110 according to the embodiment of the present invention will be specifically described with reference to the drawings. FIG. 7 is a diagram for explaining how the board case main body is attached to the case holder according to the embodiment of the present invention. Further, FIG. 8 is a perspective view showing a state in which the substrate case main body is attached to the case holder according to the embodiment of the present invention. Further, FIG. 9 is an enlarged view of the periphery of the rotation shaft of the base portion in a state where the substrate case main body is attached to the case holder according to the embodiment of the present invention. Further, FIG. 10 is a perspective view showing a state in which the substrate case body is rotated with respect to the case holder from the state of FIG. In the substrate case main body 110, the position shown in FIG. 8 is the holding position, and the position shown in FIG. 10 is the unfolding position.

When attaching the board case main body 110 to the case holder 200, as shown in FIG. 7, the board case main body 110 is attached from the front side of the case holder 200. The case holder 200 includes a variable bearing portion 220 and a shaft mounting portion 201. The variable bearing portion 220 is supported so as to cover the outer circumference of the base portion rotating shaft 117, the shaft mounting portion 201 is an arc-shaped notch, and the caulking pin insertion portion 119 is rotatable on the shaft mounting portion 201. It will be placed. By attaching the board case body 110 to the case holder 200, as shown in FIG. 8, the variable bearing portion 220 supports the base portion rotating shaft 117 so as to cover the outer periphery thereof, and the shaft mounting portion 201 has an arc shape. The substantially cylindrical caulking pin insertion portion 119 is configured to be fitted. As a result, the caulking pin insertion portion 119 can rotate inside the shaft mounting portion 201 while the inner peripheral portion of the shaft mounting portion 201 is in contact with the outer peripheral portion of the caulking pin insertion portion 119.

As described above, the board case main body 110 is provided with a screw fixing portion 140 that is rotatable with respect to the caulking pin insertion portion 119, and the base portion rotation shaft 117 is supported by the variable bearing portion 220, and the base portion. After the rotating shaft 117 is supported by the shaft mounting portion 201, the substrate case body 110 is not easily detached from the case holder 200 by connecting the screwed portion 140 and the case holder 200 with the screws 140a.

Next, the configuration of the variable bearing portion 220 will be described. As shown in FIG. 9, the base portion rotating shaft 117 is supported by the variable bearing portion 220, but the variable bearing portion 220 includes a shaft lower support portion 221 that supports the base portion rotating shaft 117 from below. It is provided with a shaft upper support portion 222 located above the base portion rotation shaft 117. The shaft upper support portion 222 and the shaft lower support portion 221 are arranged so as to sandwich the base portion rotation shaft 117 from the vertical direction. Further, since both the lower shaft support portion 221 and the upper shaft upper support portion 222 have a shape that covers a part of the front side of the base portion rotating shaft 117, the base portion rotating shaft 117 is supported by the variable bearing portion 220. Even if it is rotated in this state, it does not easily come off from the variable bearing portion 220.

Further, the shaft lower support portion 221 has a protective cover rotating shaft 223 extending to the left. Details of the rotating shaft 223 for the protective cover will be described later. Further, the lower shaft support portion 221 does not easily bend, whereas the upper shaft support portion 222 has flexibility and can be bent in the vertical direction by applying a force. The deformation of the shaft upper support portion 222 is an elastic deformation, and when the force is stopped applied to the shaft upper support portion 222, the shaft upper support portion 222 returns to the original position. The shaft upper support portion 222 may be made of, for example, PC (polycarbonate). That is, the upper shaft support portion 222 usually has a shape that extends substantially in the horizontal direction, but easily bends in the vertical direction. Further, a gap d is formed between the shaft lower support portion 221 and the shaft upper support portion 222, and a part of the base portion rotation shaft 117 is exposed by the gap d. Further, the size of the gap d is variable due to the bending of the shaft upper support portion 222.

In this way, the base portion rotating shaft 117 is supported in a state where the outer circumference is covered by the shaft lower support portion 221 and the shaft upper support portion 222 arranged vertically, but the shaft upper support portion 222 bends. Therefore, it is easy to widen the gap d, and it is possible to easily remove the base portion rotating shaft 117 from the variable bearing portion 220. Further, since the caulking pin insertion portion 119 is also mounted on the mounting portion 201 without being fixed, the caulking pin insertion portion 119 can also be easily removed from the shaft mounting portion 201. That is, the board case body 110 can be easily removed from the case holder 200 before the screwing portion 140 and the case holder 200 are connected by the screws 140a. Further, since the screw 140a can be easily removed even after the screwing portion 140 and the case holder 200 are connected by the screw 140a, it is easy if the board case main body 110 needs to be removed for some reason. The board case body 110 can be removed.

Further, even when the screwed portion 140 and the case holder 200 are not connected by the screw 140a, the base portion rotating shaft 117 is rotatably supported by the variable bearing portion 220, and the caulking pin insertion portion 119. Is rotatably supported by the shaft mounting portion 201, so that the board case body 110 can be rotated forward with respect to the case holder 200 as shown in FIG. 10, whereby the board case can be rotated forward. The main body 110 does not easily come off. Here, the substrate case main body 110 is subjected to gravity downward, and when the substrate case main body 110 is rotated, a force is also applied to the front to some extent. On the other hand, the shaft lower support portion 221 that does not bend supports the lower portion and the lower front portion of the base portion rotation shaft 117, and the shaft mounting portion 201 is the lower portion of the caulking pin insertion portion 119. And supports the lower front. Therefore, if only the board case main body 110 is to be rotated, the board case main body is connected to the case holder 200 even if the screwed portion 140 and the case holder 200 are not connected by the screws 140a. 110 does not come off easily.

From the viewpoint of preventing fraudulent activity, it is required that the board case body 110 cannot be easily removed. However, if the board case body 110 is attached to the case holder 200, the board case can be easily removed by removing the screws 140a. The main body 110 can be removed. Specifically, the base portion rotating shaft 117 can be removed from the variable bearing portion 220 by removing the screw 140a and bending the shaft upper support portion 222 upward to widen the gap d. Further, since the caulking pin insertion portion 119 is only mounted on the shaft mounting portion 201, it can be easily removed. When attaching the board case body 110 to the case holder 200, the base portion rotating shaft 117 may be inserted into the variable bearing portion 220 from the right direction, or the shaft upper support portion 222 may be bent upward. The base rotation shaft 117 may be fitted into the variable bearing portion 220 from the front.

Since the board case body 110 can be easily removed from the case holder 200 in this way, even if the board case body 110 needs to be removed for some reason such as inspection or inspection, it can be easily removed without damaging the members. be able to. Even with the screws 140a attached, the screw fastening portion 140 is rotatably attached to the caulking pin insertion portion 119 as described above, so that the board case main body 110 is moved forward as shown in FIG. It is possible to rotate to.

The lower shaft support portion 221 may be integrated with the case holder 200, but the upper shaft support portion 222 is preferably separated from the case holder 200. That is, the case holder 200 is manufactured by injection molding using, for example, a mold, and the shaft lower support portion 221 may also be manufactured integrally with the case holder 200 during this injection molding. On the other hand, it is preferable that the shaft upper support portion 222 is manufactured separately from the case holder 200 without being integrally injection-molded with the case holder 200, and is retrofitted to the case holder 200. As a result, the shaft upper support portion 222 can be easily adjusted by making it a flexible material or reducing the thickness, unlike the member integrally manufactured by injection molding. Therefore, the shaft upper support portion 222 having the desired properties can be easily manufactured. Further, by retrofitting the shaft upper support portion 222 to the case holder 200, even if an excessive force is applied to bend the shaft upper support portion 222 and the shaft is damaged, a new shaft can be easily installed. The upper support portion 222 can be installed in the case holder 200.

(Explanation of the mounting structure of the protective cover)
When attaching the protective cover 130 to the board case main body 110, as described above, the protective cover 130 is attached to the board case main body 110 attached to the case holder 200.

The mounting structure of the protective cover 130 according to the embodiment of the present invention will be specifically described with reference to the drawings. FIG. 11 is a diagram for explaining how a protective cover is attached to the substrate case body according to the embodiment of the present invention. Further, FIG. 12 is a perspective view showing a state in which the protective cover is attached to the substrate case body according to the embodiment of the present invention. FIG. 13 is a perspective view showing a state in which the gaming machine substrate case is rotated with respect to the case holder from the state of FIG.

When attaching the protective cover 130 to the board case main body 110, as shown in FIG. 11, the protective cover 130 is attached from the front side of the board case main body 110. The protective cover 130 includes a protective cover bearing portion 131 and a connector protective portion 132. As shown in FIG. 12, the protective cover bearing portion 131 has a substantially circular through hole and is engaged with the protective cover rotating shaft 223 provided in the variable bearing portion 220. Specifically, the protective cover bearing portion 131 is supported so as to cover the outer periphery of the protective cover rotating shaft 223. Therefore, when the protective cover 130 is attached to the board case main body 110, the protective cover 130 is shifted to the left side (negative side in the x-axis direction) with respect to the board case main body 110 from the front side of the board case main body 110. Is brought close to each other, and the through hole of the protective cover bearing portion 131 is passed through the protective cover rotating shaft 223 from the left side of the protective cover rotating shaft 223. The protective cover rotation shaft 223 is provided substantially parallel to the base rotation shaft 117. The connector protection unit 132 covers the connectors 116a and 116b and protects them from the outside. Further, the connector protection unit 132 can also prevent the terminals connected to the connectors 116a and 116b from being replaced by an illegal act or the terminals from being illegally connected.

As described above, the protective cover 130 is attached to the board case main body 110 so that the protective cover rotating shaft 223 penetrates the protective cover bearing portion 131. At this time, the connector protection portion 132 is arranged so as to cover the connectors 116a and 116b. After attaching the protective cover 130 to the board case main body 110, the board case main body 110 and the protective cover 130 may be connected by screws 133. In this way, with the protective cover rotating shaft 223 penetrating the protective cover bearing portion 131, the substrate case main body 110 and the protective cover 130 are integrated to form the gaming machine substrate case 100. The board case 100 cannot be easily removed from the case holder 200. Specifically, the movement of the gaming machine substrate case 100 in the vertical direction and the front-rear direction is restricted by the protective cover bearing portion 131. Further, since the shaft lower support portion 221 is sandwiched from the left and right by the protective cover bearing portion 131 and the end surface of the substrate case main body 110, the substrate for the gaming machine is not separated from the substrate case main body 110 and the protective cover 130. The movement of the case 100 in the left-right direction is also restricted.

Therefore, in the case of the board case body 110 to which the protective cover 130 is not attached, the protective cover 130 could be easily removed from the case holder 200 by simply removing the screws 140a from the case holder 200. However, the protective cover 130 can be removed from the board case body 110. By attaching it to the case holder 200, it becomes difficult to remove it from the case holder 200. Further, by attaching the protective cover 130, the connectors 116a and 116b are protected.

Here, since the inner diameter of the protective cover bearing portion 131 is sufficiently larger than the outer diameter of the protective cover rotating shaft 223, as shown in FIG. 13, a gaming machine in which the substrate case main body 110 and the protective cover 130 are integrated. The board case 100 can also be rotated forward with respect to the case holder 200. That is, although it is difficult to remove the gaming machine board case 100 from the case holder 200, it can be rotated forward with respect to the case holder 200. By rotating the gaming machine board case 100 forward with respect to the case holder 200, the back surface of the gaming machine board case 100, which is on the case holder 200 side and is not exposed to the outside, is exposed before the rotation. Will be done. As a result, even if a fraudulent act is performed by damaging the back surface of the gaming machine board case 100, it can be easily recognized.

As described above, the protective cover 130 includes a protective cover bearing portion 131 and a connector protective portion 132. Here, the protective cover bearing portion 131 is for making it difficult for the gaming machine substrate case 100 to come off from the case holder 200. Further, the connector protection unit 132 protects the connectors 116a and 116b. That is, the protective cover 130 has these a plurality of functions. Since a plurality of functions can be shared by one member in this way, the number of parts can be reduced. Therefore, space saving and cost reduction are possible.

(Explanation of caulking pin mounting structure)
When the caulking pin 400 is inserted into the caulking pin insertion portion 119 and attached, it is attached to the caulking pin insertion portion 119 of the gaming machine board case 100 attached to the case holder 200 as described above.

The mounting structure of the caulking pin 400 according to the embodiment of the present invention will be specifically described with reference to the drawings. FIG. 14 is a perspective view showing an external configuration of a caulking pin according to an embodiment of the present invention, and FIGS. 14 (a) and 14 (b) are perspective views viewed from different angles. Further, FIG. 15 is an enlarged view of the vicinity of the caulking pin insertion portion in FIG. 6, FIG. 15 (a) is a perspective view, and FIG. 15 (b) is a view seen from the front side. Further, FIG. 16 is a diagram for explaining how the caulking pin is inserted into the caulking pin insertion portion according to the embodiment of the present invention. Further, FIG. 17 is a perspective view showing the inner configuration of the caulking pin insertion portion according to the embodiment of the present invention. Further, FIG. 18 is a perspective view showing a state in which the caulking pin is inserted into the caulking pin insertion portion according to the embodiment of the present invention. Further, FIG. 19 is a diagram for explaining how the caulking pin is inserted into the caulking pin insertion portion obtained by cutting a part of the embodiment of the present invention. Further, FIG. 20 is a perspective view showing a state in which the caulking pin is inserted into the caulking pin insertion portion obtained by partially cutting the embodiment of the present invention.

First, the configuration of the caulking pin 400 will be described. The caulking pin 400 is inserted into the insertion hole 102 of the caulking pin insertion portion 119 as described above. The insertion hole 102 will be described later. Here, FIGS. 14 (a) and 14 (b) are perspective views of the caulking pin 400 viewed from different angles. As shown in FIG. 14, the caulking pin 400 has a substantially cylindrical caulking pin main body portion 401, a rib 402, a caulking pin claw portion 403, an instruction blocking plate 404, and an arrow portion, which are portions to be inserted into the insertion hole 102. 405 and. A hollow portion 406 is formed inside the caulking pin main body 401, and as described above, the caulking pin support portion 301 (see FIG. 23) of the caulking cover 300 is inserted into the hollow portion 406.

The rib 402 is installed on the outer peripheral portion of the caulking pin main body 401, and has a shape extending along the axial direction in which the rib 402 is inserted into the caulking pin insertion portion 119. The caulking pin 400 is inserted from the right side to the left side. The caulking pin claw portion 403 is installed on the outer peripheral portion of the caulking pin main body 401 so as to project outward from the outer peripheral portion of the caulking pin main body 401. A slit 407 is formed in the caulking pin main body 401 so as to surround the caulking pin claw portion 403. Here, since the hollow portion 406 is formed inside the caulking pin main body 401, the caulking pin claw portion 403 surrounded by the slit 407 can be bent inward of the caulking pin main body 401. Specifically, when a force is applied to the caulking pin claw portion 403, the caulking pin main body portion 401 bends due to elastic deformation. When this force is released, the caulking pin claw portion 403 returns to the original position. The rib 402 and the caulking pin claw portion 403 are both inserted into the caulking pin insertion hole 102 when the caulking pin main body portion 401 is inserted into the caulking pin insertion hole 102. When the caulking pin main body 401 is inserted into the insertion hole 102, the caulking pin claw portion 403 comes into contact with the inner wall of the insertion hole 102 and bends inward of the caulking pin main body 401. The instruction blocking plate 404 is arranged so as to cover the instruction portion 101 (see FIG. 16) which is a part of the outer peripheral portion of the caulking pin insertion portion 119 when the caulking pin main body portion 401 is inserted into the insertion hole 102. The width of the instruction blocking plate 404 is the distance w1. Further, the arrow portion 405 is for informing the user of the correct insertion position when inserting the caulking pin 400.

Next, the configuration of the caulking pin insertion portion 119 will be described. As shown in FIGS. 15 (a) and 15 (b), the caulking pin insertion portion 119 is formed with an insertion hole 102 into which the caulking pin 400 is inserted. Further, an indicator portion 101 is formed on the outer periphery of the caulking pin insertion portion 119. Specifically, the character "B" and the character "C" are formed on the indicator 101. The instruction unit 101 informs the user of the position where the caulking pin 400 is to be inserted into the caulking pin insertion unit 119. Although the details will be described later, the caulking pin 400 is inserted into the caulking pin 400 in a state where the arrow portion 405 is aligned with the “B” or “C” of the indicating portion 101.

When the caulking pin 400 is inserted into the caulking pin insertion portion 119, as shown in FIG. 16, the caulking pin 400 is inserted into the caulking pin insertion portion 119 from the right side with the gaming machine board case 100 attached to the case holder 200. Will be inserted into. When the caulking pin 400 is completely inserted into the caulking pin insertion portion 119, the caulking pin 400 covers the screwing portion 140 and the screw 140a as shown in FIG. Therefore, when the caulking pin 400 is inserted into the caulking pin insertion portion 119, it becomes difficult to remove the screw 140a, and it becomes difficult to remove the gaming machine board case 100 from the case holder 200.

Further, when the caulking pin 400 is inserted into the insertion hole 102, the caulking pin claw portion 403 is caught by the caulking pin locking portion 104 (see FIG. 17) of the caulking pin insertion portion 119, and the caulking pin 400 is pulled out from the caulking pin insertion portion 119. Becomes difficult. However, the caulking pin insertion portion 119 according to the present embodiment includes two caulking pin locking portions (difficult to release portion, removal restriction portion) 104, and the caulking pin is inserted by cutting off the first caulking pin locking portion 104. The caulking pin 400 can be pulled out from the portion 119. However, since there are two caulking pin locking portions 104, if the caulking pin 400 is pulled out twice, the caulking pin insertion portion 119 cannot be used.

Further, thin-walled portions 103, which are thin portions, are formed above and below the letters "B" and "C". The thin-walled portion 103 is a portion where it is easy to cut this portion with a tool such as a nipper or a knife. As will be described later, by cutting the thin-walled portion 103, the caulking pin 400 inserted into the caulking pin insertion portion 119 can be pulled out. Further, the distance w2 between the thin-walled portions 103 formed above and below the letters "B" and "C" is smaller than the distance w1 which is the width of the instruction blocking plate 404. Although the details will be described later, since the distance w2 is smaller than the distance w1, the thin-walled portion 103 can be covered with the instruction blocking plate 404, and the thin-walled portion 103 can be prevented from being cut.

When the caulking pin main body 401 is inserted into the insertion hole 102 of the caulking pin insertion portion 119, the caulking pin 400 is inserted so that the rib 402 is fitted into the groove 105 formed in the caulking pin insertion portion 119. The groove 105 is formed in the inner peripheral portion of the insertion hole 102 along the direction in which the caulking pin 400 is inserted. Therefore, if the rib 402 is not in the direction of fitting into the groove 105, the caulking pin main body 401 cannot be inserted into the caulking pin insertion portion 119. That is, the caulking pin 400 is positioned in the rotation direction with the insertion direction of the caulking pin 400 as the rotation axis. By inserting the arrow portion 405 of the caulking pin 400 so as to point to the letter "B" of the indicating portion 101 of the caulking pin insertion portion 119, each member is arranged so that the rib 402 fits into the groove portion 105. Then, when the caulking pin 400 is inserted into the insertion hole 102 in this way, the caulking pin claw portion 403 is caught by the caulking pin locking portion 104.

As shown in FIGS. 15 and 17, a hole 104a is formed in the inner wall of the insertion hole 102, and the end portion of the hole 104a is a caulking pin locking portion 104. The caulking pin locking portion 104 is formed at the end of the hole 104a on the indicator 101 side. There are two caulking pin locking portions 104, and they are formed at positions advanced from "B" and "C" of the indicating portion 101 along the direction in which the caulking pin 400 is inserted. As described above, the rib 402 and the groove 105 position the caulking pin 400, and the caulking pin claw portion 403 is guided to the caulking pin locking portion 104. When the caulking pin 400 is inserted into the caulking pin insertion portion 119 so that the arrow portion 405 points to the letter "B" of the indicator portion 101, the rib 402 is fitted into the groove portion 105. At this time, the caulking pin claw portion 403 passes through the position on the inner wall of the insertion hole 102 on the back side where the “B” of the indicator portion 101 is described. When the caulking pin main body 401 is inserted into the insertion hole 102, as described above, the caulking pin claw portion 403 is pushed by the inner wall of the insertion hole 102 and inserted in a state of being bent inward of the caulking pin main body 401. .. Then, when the caulking pin locking portion 104 is reached, the caulking pin claw portion 403 returns to the original state and is caught by the caulking pin locking portion 104. Therefore, it becomes difficult to remove the caulking pin 400 from the caulking pin insertion portion 119.

As described above, when the caulking pin 400 is inserted into the caulking pin insertion portion 119, as shown in FIG. 18, the screw 140a screwed to the screwing portion 140 is covered by the caulking pin 400. It becomes difficult to remove it, and it becomes difficult to remove the gaming machine board case 100 from the case holder 200. Further, when the caulking pin 400 is inserted into the caulking pin insertion portion 119, the tip of the caulking pin main body portion 401 penetrates the base portion 111, reaches the notch 118 of the cover portion 112, and fits into the notch 118. .. As a result, it becomes difficult to slide the cover portion 112 with respect to the base portion 111 in order to separate the cover portion 112, and thus it becomes difficult to separate the base portion 111 and the cover portion 112. Even with the caulking pin 400 attached, it is possible to rotate the gaming machine board case 100 with respect to the case holder 200.

Further, when the caulking pin 400 is inserted into the caulking pin insertion portion 119 and inserted to a state where it is difficult to remove the caulking pin 400, the instruction blocking plate 404 is arranged so as to cover the letter "C" of the instruction unit 101, and the instruction unit It makes it difficult to see the letter "C" in 101. Further, as described above, since the distance w2 between the thin-walled portions 103 is smaller than the distance w1 which is the width of the indicator blocking plate 404, not only the letter "C" of the indicator portion 101 but also above and below it. The formed thin-walled portion 103 is also covered with the instruction blocking plate 404. As a result, even if an attempt is made to cut the thin-walled portion 103, it is difficult to cut the thin-walled portion 103 because the thin-walled portion 103 is covered with the instruction blocking plate 404.

Further, in particular, as shown in FIG. 16, in the caulking pin insertion portion 119, the caulking pin insertion portion 119 corresponding to the right side (positive side in the x-axis direction) of the characters “B” and “C” of the indicator portion 101. A thin portion is formed at the edge portion, and the structure has a step. By inserting a tool such as nippers into this thin portion, the thin portion 103 is cut. Here, as shown in FIG. 18, when the caulking pin 400 is inserted into the caulking pin insertion portion 119 and the instruction blocking plate 404 is arranged so as to cover the letter “C” of the instruction unit 101, the instruction unit 101 The thin portion of the edge portion of the caulking pin insertion portion 119 on the right side of the letter "B" is exposed, and by inserting a tool such as nippers into this portion, the upper and lower parts of the letter "B" of the indicator portion 101 are exposed. The thin-walled portion 103 formed in the above can be cut. On the other hand, the edge portion of the caulking pin insertion portion 119 on the right side of the letter "C" of the indicator portion 101 is covered with the caulking pin 400, and the thin portion is not exposed. Therefore, it is difficult to cut the thin portion 103 formed above and below the letter "C" of the indicator portion 101.

As described above, when the caulking pin 400 is inserted into the caulking pin insertion portion 119, the caulking pin claw portion 403 is caught by the caulking pin locking portion 104 and it is difficult to pull out the caulking pin 400. Can be done. However, it may be necessary to properly remove the caulking pin 400 from the caulking pin insertion portion 119 and remove the gaming machine board case 100 from the case holder 200 by inspection or inspection. In such a case, in the state shown in FIG. 18, the thin-walled portion 103 provided in the vicinity of “B” of the indicator portion 101 is cut with a tool such as a nipper or a knife. Specifically, by cutting the two thin-walled portions 103 above and below the "B", the "B" portion of the indicating portion 101 is cut off. As a result, the excised portion and the hole 104a forming the caulking pin locking portion 104 are integrated, and the caulking pin locking portion 104 formed in "B" of the indicator portion 101 is also removed (FIG. 19). reference). Since the caulking pin locking portion 104 is removed, there is no member on which the caulking pin claw portion 403 is caught, so that the caulking pin 400 can be pulled out from the caulking pin insertion portion 119.

If the "C" portion of the indicator 101 is accidentally cut off instead of the "B" portion of the indicator 101, not only the caulking pin 400 cannot be pulled out, but also the caulking pin 400 cannot be pulled out. It is necessary to further cut off the "B" portion of 101, and both the caulking pin locking portions 104 are removed, which eventually causes a problem that the caulking pin inserting portion 119 cannot be used again. However, as described above, since the instruction blocking plate 404 covers the character "C" of the instruction unit 101, it is difficult to visually recognize the character "C" of the instruction unit 101, and the user erroneously gives an instruction. It is possible to prevent a problem when the "C" portion of the portion 101 is cut off. Further, it is difficult to cut the thin-walled portion 103 because not only the letter "C" of the indicator portion 101 but also the thin-walled portion 103 formed above and below the indicating portion 101 is covered with the instruction blocking plate 404. Therefore, even if the caulking pin 400 is transparent and the letter "C" of the indicator 101 can be visually recognized, it is difficult to cut the thin portion 103, and there is a problem that the "C" portion is accidentally cut off. Can be prevented. In this way, when the caulking pin 400 is inserted into the caulking pin insertion portion 119, the caulking pin locking portion 104 formed at a position advanced along the direction in which the caulking pin 400 is inserted from the “B” of the indicating portion 101 is removed. However, since the thin-walled portion 103 is covered by the indicator blocking plate 404, it is difficult to cut off the “C” portion of the indicator 101, and the caulking pin 400 is inserted from the “C” of the indicator 101. It is difficult to remove the caulking pin locking portion 104 formed at a position advanced along the direction.

As shown in FIG. 19, in the caulking pin insertion portion 119 in which the “B” portion of the indicator portion 101 is excised, the caulking pin locking portion 104 is formed by excising the “B” portion of the indicator portion 101. The hole 104a disappears, the caulking pin locking portion 104 is removed, and a new reinsertion groove portion (new groove portion) 106 is formed. When the caulking pin 400 is inserted into the caulking pin insertion portion 119 again, the rib 402 may be inserted so as to fit into the reinsertion groove portion 106. As a result, the caulking pin claw portion 403 is caught by the remaining caulking pin locking portion 104.

As described above, by cutting the thin-walled portion 103 and cutting off the "B" portion of the indicator portion 101, the caulking pin 400 is pulled out from the caulking pin insertion portion 119, and then the caulking pin 400 is inserted into the caulking pin insertion portion 119 again. In this case, as shown in FIG. 19, the arrow portion 405 of the caulking pin 400 may be inserted so as to point to the letter “C” of the indicating portion 101 of the caulking pin insertion portion 119. When the caulking pin 400 is inserted into the caulking pin insertion portion 119 so that the arrow portion 405 points to the letter "C", each member is arranged so that the rib 402 is fitted into the reinsertion groove portion 106. By inserting the caulking pin 400 into the caulking pin insertion portion 119 in this way, the caulking pin claw portion 403 is caught by the remaining caulking pin locking portion 104, and it becomes difficult to remove the caulking pin 400. That is, the caulking pin 400 is positioned on the rib 402 and the reinsertion groove portion 106, and the caulking pin claw portion 403 is guided to the caulking pin locking portion 104.

Specifically, when the caulking pin 400 is inserted into the caulking pin insertion portion 119 so that the arrow portion 405 points to the letter "C" of the indicator portion 101, the rib 402 is fitted into the reinsertion groove portion 106 and the caulking pin 400 is inserted. The caulking pin claw portion 403 can pass through the position on the inner wall of the insertion hole 102 on the back side where the "C" of the indicator portion 101 is described. When the caulking pin main body 401 is inserted into the insertion hole 102, as described above, the caulking pin claw portion 403 is pushed by the inner wall of the insertion hole 102 and inserted in a state of being bent inward of the caulking pin main body 401. To. Then, when the caulking pin locking portion 104 is reached, the caulking pin claw portion 403 returns to the original state and is caught by the caulking pin locking portion 104. This makes it difficult to remove the caulking pin 400 from the caulking pin insertion portion 119.

As described above, by attaching the caulking pin 400 to the gaming machine board case 100 attached to the case holder 200, the screw 140a is covered by the caulking pin 400, and it becomes difficult to remove the case holder 200. Further, when the caulking pin 400 is inserted into the caulking pin insertion portion 119, it is difficult to remove the caulking pin 400. Further, it may be necessary to remove the board case 100 for a gaming machine for a legitimate reason such as inspection or inspection. In that case, the caulking pin 400 can be easily removed by damaging a part of the caulking pin insertion portion 119. be able to. Even in this case, the caulking pin 400 can be inserted into the caulking pin insertion portion 119 again without replacing the member, making it difficult to remove the case holder 200. In order to use the caulking pin 400 again, it is necessary to follow a fixed procedure, and the structure of the caulking pin 400 is a structure capable of preventing this procedure.

(Explanation of the caulking cover mounting structure)
As described above, the caulking cover 300 is attached to the case holder 200 from the right side of the case holder 200 so as to cover the caulking pin 400 inserted in the caulking pin insertion portion 119.

The mounting structure of the caulking cover 300 according to the embodiment of the present invention will be specifically described with reference to the drawings. FIG. 21 is a diagram for explaining how the caulking cover according to the embodiment of the present invention is attached to the case holder. Further, FIG. 22 is a perspective view showing the operation of the moving engaging portion according to the embodiment of the present invention, and FIG. 22 (a) is a view showing a case where the moving engaging portion is located below. b) is a diagram showing a case where the moving engaging portion is above.

As shown in FIG. 21, the caulking cover 300 is attached so as to cover the caulking pin 400 from the right side of the case holder 200 attached to the housing body 10a. Although the details will be described later, by attaching the caulking cover 300, the regulation lock pin 310 (see FIG. 23) provided inside the caulking cover 300 is pushed into the moving engaging portion 210 to be loaded and connected. .. Here, as shown in FIG. 22, the mobile engaging portion 210 is movable. Specifically, the rail fitting portion 213 (see FIG. 25) of the moving engaging portion 210 is fitted into the guide rail 202 provided on the case holder 200, and is guided by the guide rail 202 so that the sliding movement is possible. is there. Specifically, the moving engaging portion 210 can move up and down in a state where the case holder 200 is attached to the housing body 10a. FIG. 22 (a) is a diagram showing the case where the moving engaging portion 210 is at the lower side (when the moving engaging portion 210 is closer to the caulking pin 400), and FIG. 22 (b) is a diagram showing the case where the moving engaging portion 210 is at the upper side. It is a figure which shows the case (the case where the moving engaging part 210 is separated from the caulking pin 400). When the case holder 200 is assembled, the mobile engaging portion 210 is located below, as shown in FIG. 22 (a). The reason why the movable engaging portion 210 is movable is to change the position according to the regulation lock pin 310 to be loaded. Thereby, two regulation lock pins 310 provided on the caulking cover 300 can be selected and used.

Further, as shown in FIG. 21, a thin-walled portion 302 is formed on the caulking cover 300. The thin-walled portion 302 is a portion that is thinner than the surroundings and is a portion that can be easily cut with a tool such as a nipper or a knife. Although the details will be described later, the regulation lock pin 310 can be separated from the caulking cover 300 by cutting the thin portion 302. By attaching the caulking cover 300 to the case holder 200, the regulation lock pin 310 is inserted into the moving engaging portion 210, and these cannot be easily separated. This also makes it difficult to remove the caulking cover 300. Therefore, by attaching the caulking cover 300, the caulking pin 400 is covered so as not to be exposed from the outside, and fraudulent acts such as removing the board case 100 for the gaming machine can be suppressed.

Next, a state in which the caulking cover 300 is attached to the mobile engaging portion 210 will be described with reference to the drawings. FIG. 23 is a diagram showing a configuration of a caulking cover according to an embodiment of the present invention, FIG. 23 (a) is a perspective view, FIG. 23 (b) is a front view, and FIG. 23 (c) is a bottom surface. It is a figure. Note that FIG. 23A is a perspective view showing the configuration of the caulking cover 300, and the surface facing the case holder 200 when attached to the case holder 200 is the front surface. 23 (b) is a front view in FIG. 23 (a), and FIG. 23 (c) is a bottom view in FIG. 23 (a). As shown in FIG. 23, the caulking cover 300 includes two regulation lock pins 310 and a caulking pin support portion 301. Further, thin-walled portions 302 are formed at positions corresponding to the regulation lock pins 310, respectively.

When the caulking cover 300 is attached to the case holder 200, the caulking pin support portion 301 is inserted into the hollow portion 406 formed inside the caulking pin main body portion 401 of the caulking pin 400. As a result, the caulking pin 400 is supported by the caulking pin support portion 301. Further, since the caulking pin support portion 301 is present in the hollow portion 406, the caulking pin claw portion 403 is restricted from bending inward of the caulking pin main body portion 401. Therefore, for example, by bending the caulking pin claw portion 403 inward of the caulking pin main body portion 401, the caulking pin claw portion 403 is prevented from being caught by the caulking pin locking portion 104, and an illegal act of pulling out the caulking pin 400 is prevented. Can be done. Further, since the caulking cover 300 is attached, the caulking pin 400 is covered by the caulking cover 300, which makes it difficult to remove the caulking pin 400. Therefore, even if an attempt is made to remove the caulking pin 400 due to fraudulent activity or the like, it is difficult to remove the caulking pin 400 by the caulking pin support portion 301 with the caulking cover 300 attached.

Further, the regulation lock pin 310 is pushed into the moving engaging portion 210 and becomes difficult to pull out. Since it becomes difficult to remove the regulation lock pin 310 from the moving engaging portion 210, it becomes difficult to remove the caulking cover 300 from the case holder 200, and fraudulent activity can be suppressed. The movable engaging portion 210 is movable, and one of the regulation lock pins 310 may be pushed in and loaded. However, when the case holder 200 is attached, the regulation lock pin 310 is arranged closer to the caulking pin 400. Therefore, when the caulking cover 300 is attached for the first time (see FIG. 22A), the regulation lock pin 310 closer to the caulking pin 400 is pushed into the moving engaging portion 210 and loaded.

Further, as described above, the thin portion 302 is formed so as to correspond to each regulation lock pin 310. When the caulking cover 300 is attached to the case holder 200, it becomes difficult to remove it. However, if it becomes necessary to properly remove the board case 100 for a gaming machine due to inspection or inspection, it is necessary to remove the caulking cover 300. It becomes. In this case, the thin portion 302 corresponding to the regulation lock pin 310 charged in the mobile engaging portion 210 is cut with a tool such as a nipper or a knife. When the caulking cover 300 is removed for the first time, since the regulation lock pin 310 closer to the caulking pin 400 is installed in the moving engaging portion 210, the thin portion 302 formed closer to the caulking pin 400 may be cut. As a result, the regulation lock pin 310 is separated from the caulking cover 300, so that the caulking cover 300 can be removed. The regulation lock pin 310 incorporated in the mobile engaging portion 210 may be removed by breaking it.

When the caulking cover 300 is attached again, the moving engaging portion 210 is moved to a position away from the caulking pin 400 so as to correspond to the remaining regulation lock pin 310 (see FIG. 22B). The caulking cover 300 may be attached so that the regulation lock pin 310 is inserted into the moving engaging portion 210. As described above, according to the caulking cover 300, since it can be attached to the case holder 200 so as to cover the caulking pin 400 in a state where it is difficult to remove, fraudulent activity can be suppressed. Further, when the caulking cover 300 is legally removed, it can be reattached after the caulking cover 300 is removed, so that it is not necessary to use a new caulking cover 300, and the cost can be suppressed.

Next, a state in which the regulation lock pin 310 is installed in the mobile engaging portion 210 will be described. FIG. 24 is a diagram for explaining how the regulation lock pin is attached to the mobile engaging portion according to the embodiment of the present invention, and FIG. 24 (a) is a diagram showing a state before charging. 24 (b) is a diagram showing a state after charging. Here, FIG. 24 is a diagram showing only the mobile engaging portion 210 and the regulation lock pin 310 extracted in consideration of legibility. When the caulking cover 300 is attached to the case holder 200, as shown in FIG. 24A, the regulation lock pin 310 is pushed into the moving engaging portion 210 to be loaded. Specifically, the lock pin portion 320 of the regulation lock pin 310 is pushed into the inlet 211 of the mobile engagement portion 210. Here, the end surface of the notch portion 215a formed in the moving engaging portion 210 becomes the lock pin locking portion 215 that engages with the lock pin portion 320. Therefore, the lock pin locking portion 215 is continuously formed on the inner wall of the inlet 211 and is substantially perpendicular to the inner wall of the inlet 211. When the lock pin portion 320 is pushed into the inlet 211 of the mobile engaging portion 210, the lock pin portion 320 penetrates the inlet 211 and the lock pin portion 320 at the inlet 211, as shown in FIG. 24 (b). By engaging the lock pin portion 320 with the lock pin locking portion 215, which is the end surface of the notch portion 215a formed on the side opposite to the side to which the lock pin portion 320 is inserted, the mobile engaging portion 210 and the regulation lock pin 310 Are linked to difficulty in separation.

Next, the configuration of the mobile engaging portion 210 will be described with reference to the drawings. 25 is a view showing an external configuration of a mobile engaging portion according to an embodiment of the present invention, FIG. 25 (a) is a perspective view, FIG. 25 (b) is a front view, and FIG. 25 (c). ) Is a bottom view. Note that FIG. 25A is a perspective view showing the configuration of the mobile engaging portion 210, with the surface facing the regulation lock pin 310 when the regulation lock pin 310 is inserted as the front surface. 25 (b) is a front view in FIG. 25 (a), and FIG. 25 (c) is a bottom view in FIG. 25 (a). As shown in FIG. 25, the moving engaging portion 210 is for fitting the lock pin portion 320 into the inlet 211 and the guide rail 202 as described above so that the moving engaging portion 210 can move. It includes a rail fitting portion 213, a guide portion 212, and a wedge portion 214.

As described above, the inlet 211 is formed with a lock pin locking portion 215 that engages with the lock pin portion 320 and makes it difficult to remove the regulation lock pin 310 from the mobile engaging portion 210. The guide portion 212 is for guiding the operation of the restraint piece 331 of the regulation lock pin 310, which will be described later. The wedge portion 214 is for guiding the arm 321 when the arm 321 of the regulation lock pin 310, which will be described later, is loaded, and after guiding the arm 321 to limit the deformation of the arm 321. It has a shape that gradually spreads from. Further, the wedge portion 214 is formed in a stepped shape so as to gradually inward toward the charging direction of the regulation lock pin 310.

Next, the configuration of the regulation lock pin 310 will be described with reference to the drawings. 26 is a view showing an external configuration of a regulation lock pin according to an embodiment of the present invention, FIG. 26 (a) is a perspective view, FIG. 26 (b) is a front view, and FIG. 26 (c) is a front view. Is a bottom view. Note that FIG. 26A is a perspective view showing the configuration of the regulation lock pin 310, and the surface facing the moving engaging portion 210 when pushed into the moving engaging portion 210 is the front surface. 26 (b) is a front view in FIG. 26 (a), and FIG. 26 (c) is a bottom view in FIG. 26 (a). As shown in FIG. 26, the regulation lock pin 310 includes a lock pin portion 320 and a stopper portion 330.

27 is a diagram showing an external configuration of a lock pin portion according to an embodiment of the present invention, FIG. 27 (a) is a perspective view, FIG. 27 (b) is a front view, and FIG. 27 (a) is a front view. c) is a bottom view. Note that FIG. 27A is a perspective view showing the configuration of the lock pin portion 320, and the surface facing the moving engaging portion 210 when the regulation lock pin 310 is pushed into the moving engaging portion 210 is the front surface. 27 (b) is a front view in FIG. 27 (a), and FIG. 27 (c) is a bottom view in FIG. 27 (a). As shown in FIG. 27, the lock pin portion 320 includes an arm 321 that is pushed into the charging inlet 211 and loaded, and a lock pin claw portion 322 formed at the tip of the arm 321. The arm 321 is composed of four arms, and two arms 321 are arranged side by side in the vertical direction and the horizontal direction. The arm 321 is flexible and can be elastically deformed. When the arm 321 is pushed from one end of the inlet 211, the lock pin claw portion 322 is guided by the inner wall of the inlet 211, and the arm 321 bends and deforms so as to gather inward in the lateral direction while being deformed inside the inlet 211. Will be charged to. Further, the arms 321 gathered inward in the horizontal direction are guided by the stepped portion of the wedge portion 214, and bend and deform so as to gather inward in the vertical direction.

In this way, the lock pin claw portion 322 is loaded into the inlet 211 and guided by the inner wall of the inlet 211 so as to gather inward in the lateral direction while passing through the inlet 211. Further, since the arm 321 is guided by the wedge portion 214 so as to gather inward in the vertical direction while passing through the inlet 211, the lock pin claw portion 322 gathers inward also in the vertical direction. However, when the lock pin claw portion 322 reaches the notch portion 215a, the lock pin claw portion 322 is released from the inner wall of the inlet 211 and opens again outward in the lateral direction. Further, when the lock pin claw portion 322 opens outward in the horizontal direction, the arm 321 is released from the wedge portion 214 and opens again outward in the vertical direction. As a result, the lock pin claw portion 322 engages with and is caught by the lock pin locking portion 215, and it becomes difficult to pull out the regulation lock pin 310 from the moving engaging portion 210. However, as shown in FIG. 26, usually, the restraining piece 331 exists between the arms 321 arranged in the vertical direction, and it is difficult to deform the arms 321 to bend and approach each other in the vertical direction.

Further, FIG. 28 is a diagram showing an external configuration of a stopper portion according to an embodiment of the present invention, FIG. 28 (a) is a perspective view, FIG. 28 (b) is a front view, and FIG. 28 (c). ) Is a bottom view. Note that FIG. 28A is a perspective view showing the configuration of the stopper portion 330, with the surface facing the moving engaging portion 210 when the regulation lock pin 310 is pushed into the moving engaging portion 210 as the front surface. 28 (b) is a front view in FIG. 28 (a), and FIG. 28 (c) is a bottom view in FIG. 28 (a). As shown in FIG. 28, the stopper portion 330 is integrated with the two guided portions 332 and the guided portion 332 that are engaged with and guided by the guide portion 212, and each operates integrally with the guided portion 332. It is equipped with two restraint pieces 331. Here, the stopper portion 330 has flexibility and can be elastically deformed. As a result, the guided portions 332 can move in directions away from each other. Similarly, the restraining piece 331 can also move in a direction away from each other.

Next, the operation of the stopper portion 330 when the regulation lock pin 310 is pushed into the mobile engaging portion 210 to be loaded will be described with reference to the drawings. FIG. 29 is a bottom view showing the operation of the stopper portion when the regulation lock pin is loaded into the mobile engaging portion according to the embodiment of the present invention, and FIG. 29 (a) is a view before loading. FIG. 29 (b) is a diagram during charging, and FIG. 29 (c) is a diagram after charging. Here, FIG. 29 is a diagram showing only the moving engaging portion 210 and the stopper portion 330 extracted in consideration of legibility.

As shown in FIG. 29 (a), the shape of the stopper portion 330 has not changed and the restraining piece 331 is close to the arm 321 before the regulation lock pin 310 is loaded into the mobile engaging portion 210. , Exists between the arms 321 arranged in the vertical direction. At the time of charging, the guided portion 332 of the stopper portion 330 comes into contact with the guide portion 212. The surface of the guided portion 332 that comes into contact with the guide portion 212 is formed obliquely with respect to the guide portion 212, and as the regulation lock pin 310 is pushed in, the guided portion 332 is guided by the guide portion 212. It gradually moves away from each other, and the distance between them increases. At this time, the restraining pieces 331, which are integrated with the guided portion 332, also operate so as to be separated from each other, and the distance between them is widened. As a result, the restraint pieces 331 that existed between the arms 321 arranged in the vertical direction before charging (see FIG. 25) move from between the arms 321 and separate from the arms 321. Therefore, the arm 321 is released from the limitation by the restraining piece 331 and can be freely deformed in the vertical direction. Therefore, as described above, the lock pin claw portion 322 is guided by the inner wall of the inlet 211, so that the arm 321 is deformed so as to gather inward in the lateral direction, and the arm 321 gathers inward in the lateral direction. , The arm 321 can be gathered inward in the vertical direction by the wedge portion 214, and is charged inside the charging inlet 211.

Further, when the regulation lock pin 310 is pushed in and the lock pin claw portion 322 reaches the notch portion 215a, the lock pin claw portion 322 is released from the inner wall of the inlet 211 and opens again in the lateral direction to the outside. It will be. Further, when the lock pin claw portion 322 opens outward in the horizontal direction, the arm 321 is released from the wedge portion 214 and opens again outward in the vertical direction. In this state, as shown in FIG. 29 (c), the guided portion 332 is separated from the guide portion 212 and returns to the original position again. Since the restraining piece 331 is also integrated with the guided portion 332, it returns to the original position and exists between the arms 321 and the deformation of the arm 321 in the vertical direction is restricted. Further, when the arm 321 is released from the wedge portion 214 and opened outward again in the vertical direction, the wedge portion 214 is present between the arms 321 arranged in the horizontal direction, and the arm 321 is also deformed in the lateral direction. It will be restricted.
