Each of the connecting portions a2 to f2 is formed in a flat plate shape having a breakable portion, and in a state where the cover case 10 and the body case 20 are fixed, as shown in FIG. Located on the back side, the connecting parts b2 and e2 are located in the U-shaped space of the connecting parts b1 and e1, and the connecting part f2 is located inside the connecting part f1. Further, the connecting portions c2 and d2 are a set of two flat plates, and the two flat plates are positioned so as to sandwich the connecting portions c1 and d1 therebetween. Each combination of the connection parts a1 to f1 and the connection parts a2 to f2 constitutes the connection parts a to f.

  As shown in FIG. 6, the base fixing portion 30 is provided at a lower portion of the side surface of the base member 2, and has a thin plate-like fixing plate 31 protruding forward, and the inside of the fixing plate 31 (on the center side of the base member 2). The insertion piece 34 is provided. The fixed plate 31 is formed so that the plate surface is on the side, and the fixed plate 31 is provided with two pin holes 32 and 33. The pin hole 32 corresponds to the first sealing portion 4A, and the pin hole 33 corresponds to the second sealing portion 4B (see FIG. 8A). Each pin hole 32, 33 is slightly larger in diameter than the shaft portion 42 of the caulking pin 40, and is smaller than the maximum width of the twisting portion 41, and from the twist fixing holes 32A, 33A. Shaft passage grooves 32B and 33B formed in the vertical direction of the fixed plate 31 are provided. Specifically, the twist fixing hole 32A is located above the fixing plate 31, the shaft passage groove 32B is formed upward from the twist fixing hole 32A, and the upper side is open. Further, the twist fixing hole 33A is located on the upper side of the fixing plate 31, the shaft passage groove 33B is formed downward from the twist fixing hole 33A, and the lower side is open. The tail fixing holes 32A and 33A are formed to have substantially the same diameter as the pin hole 14 of the cover base caulking box 12, and the twisting portion 41 can be elastically deformed to pass therethrough. The shaft passage grooves 32B and 33B have a groove width through which the shaft portion 42 of the caulking pin 40 can pass. The insertion piece 34 is formed so as to be orthogonal to the inner surface of the fixing plate 31. When the board case 1 is fixed at an appropriate position of the base member 2, the insertion piece 34 is interposed between the first sealing portion 4A and the second sealing portion 4B. It is inserted into the gap 150 (see FIGS. 1, 6 and 7). The tip of the insertion piece 34 is formed in a mountain shape so that it can easily enter the gap 150. Further, the insertion piece 34 has openings 12A and 22A formed on the upper surface of the second sealing portion 4B when the substrate case 1 from which the first sealing portion 4A has been removed is fixed to the base member 2 again (FIG. 7). Function as a shielding plate that closes (see).

(Sealing of base plate case 1 to base member 2 and release of sealing)
Next, a procedure for sealing the substrate case 1 to the base member 2 by the above-described base sealing portion 4 will be described.
First, the substrate case 1 is fixed to the base member 2. As described above, the convex portion 120 (see FIG. 1) of the substrate case 1 is engaged with the opening 200 (see FIG. 3) of the base member 2, and the latching claws 210 of the base member 2 are elastically deformed to form the substrate case. 1 is engaged with the claw engagement gap 140 of FIG. 1 (see FIG. 2), and the screw fixing portion 130 of the substrate case 1 and the screw boss 220 of the base member 2 (see FIG. 3) are fixed with screws, whereby the substrate case 1 is Mounted on the base member 2. At this time, the fixing plate 31 of the base fixing part 30 is inserted into the insertion gap 26 of the base sealing part 4 and the insertion piece 34 is inserted into the gap 150 (see FIG. 7). The fixing plate 31 is inside the first sealing portion 4A from the opening portions 12A and 22A on the bottom surface of the first sealing portion 4A, and inside the second sealing portion 4B from the opening portions 12A and 22A on the top surface of the second sealing portion 4B. The pin fixing holes 32A and 33A of the pin holes 32 and 33 are aligned with the pin holes 14 and the pin passing holes 24 of the seal portions (FIG. 8A). (See (B)).

  Next, the two caulking pins 40 connected by the head 43 are set in the two pin guiding portions 13 of the base sealing portion 4 and are pushed in until the crimping portions 41 of both the caulking pins 40 pass through the pin holes 14. . At this time, if the head portion 43 does not match the pin guide portion 13, the tail portion 41 cannot pass through the pin hole. That is, the protruding length of the pin guide portion 13 in the lateral direction is shorter than the length of the caulking pin 40 excluding the head 43. When the rubbing portion 41 is pushed in until it passes through the pin hole 14, the elastic piece of the rubbing portion 41 passes through the hole 14 in a non-vertical state and cannot be extracted from the pin hole 14 in this state. In this state, since the caulking pin 40 is not related to the base member 2, the caulking pin 40 does not play an original role, and is in a temporarily fixed state. Further, in this state, the cover case 10 and the main body case 20 of the substrate case 1 are not crimped, so that the engaging portion (not shown) that fixes the cover case 10 and the main body case 20 is released. For example, the substrate case 1 can be opened.

  Then, among the caulking pins 40 that are temporarily fixed to the base sealing portion 4 so as not to be removed, when one of the caulking pins 40 temporarily fixed to the first sealing portion 4A, for example, is further pushed in, as shown in FIG. Furthermore, the edge portion 41 passes through the edge passage hole 24 and the edge fixing hole 32A and protrudes into the edge storage portion 25. At this time, the head portion 43 of the caulking pin 40 is close to the innermost portion of the pin guiding portion 13, that is, the side surface of the cover base caulking box 12, and as shown in FIG. It is positioned obliquely with respect to the shaft passage groove 32B so as not to coincide with the groove length direction of the groove 32B. That is, the line connecting the ends of the elastic pieces of the twisting portion 41 on the head side does not coincide with the longitudinal direction of the shaft passage groove 32B. Since the pinch portion 41 is arranged in this manner, and the head 43 is fitted to the pin guide portion 13 and cannot be rotated in the front-rear direction, the entire caulking pin 40 is not rotatable in the front-rear direction. The ends of the two elastic pieces of the twisting portion 41 on the side opposite to the pointed end are locked to the fixing plate 31, so that the tensile force in the axial direction can be countered. That is, even if the head 43 is forcibly pulled, the twisting portion 41 will not come out of the pin hole 32 unless the twisting portion 41 is destroyed. Then, the cover base caulking box 12, the main body base caulking box 22, and the fixing plate 31 are caulked by the head portion 43 and the twisting portion 41. Thereby, the substrate case 1 is fixed to the base member 2 so as not to be detached. The connecting string 44 that connects the two caulking pins 40 has a length that does not break even if one caulking pin 40 is pushed into the caulking position (see FIG. 5). One caulking pin 40 can be pushed in while 40 is still connected.

Here, since the substrate case 1 is formed of a transparent member, the caulking pin 40 pushed into the base sealing portion 4 can be viewed from the front side. And, since the caulking pin 40 is mounted at an angle at which the two elastic pieces of the rubbing portion 41 can be seen in the shape of the rubbing portion, the caulking pin 40 is broken or once pulled out, the rubbing portion 41 is broken. If it is inserted again after being done, it can be discriminated at a glance.
Next, the procedure for releasing the sealing of the first sealing portion 4A of the base sealing portion 4 will be described.
First, in order to remove the substrate case 1 from the base member 2, the connecting portions a, b, c, and f (see FIG. 1) connecting the first sealing portion 4A and the substrate case 1 are cut with a nipper or the like, The connecting string 44 of the caulking pin 40 is cut and the two caulking pins 40 are separated. Then, as shown in FIG. 9, the screw that fastens the screw fixing portion 130 and the screw boss 220 is removed, and the locking claw 210 that is engaged with the claw engagement gap 140 is elastically deformed, so that the claw engagement gap 140 is removed. If the convex portion 120 (see FIG. 1) is pulled out from the opening 200 (see FIG. 3) after the sealing portion side (front right side) of the substrate case 1 is rotated forward, the substrate case 1 is removed from the base member. 2 can be removed. At this time, the cut first sealing portion 4A remains left on the base fixing portion 30 of the base member 2.

To remove the first sealing portion 4A from the base fixing portion 30, first, as shown in FIG. 10B, the first sealing portion 4A is lifted upward. Then, since the shaft portion 42 of the caulking pin 40 moves from the twist fixing hole 32A to the shaft passage groove 32B, the entire first sealing portion 4A can be moved upward. The first sealing portion 4A is further moved upward, and when the shaft portion 42 has come out of the shaft passage groove 32B, the first sealing portion 4A is moved to the near side as shown in FIG. Thereby, the fixing plate 31 is removed from the insertion gap 26, and the first sealing portion 4A can be removed.
Here, when the first sealing portion 4A is not separated from the substrate case 1, the caulking pin 40 is broken because the shaft portion 42 of the caulking pin 40 passes through the pin hole 32 as shown in FIG. Unless this is done, the substrate case 1 cannot be moved to the near side. If the board case 1 is not moved to the front side, the engagement between the locking claw 210 and the claw engagement gap 140 and the engagement between the insertion piece 34 and the gap 150 cannot be released. It cannot be moved to. Therefore, it is impossible to remove the substrate case 1 by moving the first sealing portion 4A from the base fixing portion 30 as described above without destroying the caulking pins 40.

As described above, the base sealing portion 4 in the present embodiment is fixed in such a manner that the caulking pin 40 is attached to the transparent sealing portion from the lateral direction, and when the front view is viewed, the closing portion 41 can be seen in the form of a closing edge. It is possible to easily confirm whether the caulking pin 40 is properly installed, and when the breakage part 41 is destroyed or the caulking pin 40 is pulled out and reattached. Can be seen at first glance.
Even if the seal is properly released, if the caulking pin 40 is destroyed, the debris may fall into the gaming machine and adversely affect the internal device. In this embodiment, the pin of the base fixing portion 30 Since the shaft passage grooves 32B and 33B are provided in the holes 32 and 33 so that the sealing portion can be detached from the substrate case 1 and removed from the base fixing portion 30 without breaking the caulking pin 40, such a problem does not occur.

In addition, the caulking pin 40 is inserted in a direction rotated by a predetermined angle about the shaft center so that the locking force of the fastening portion 41 of the caulking pin 40 is not impaired by providing the shaft passage grooves 32B and 33B. A pin guide portion 13 is provided to disable the caulking pin 40 from rotating in the front-rear direction. As a result, it is possible to prevent the crimping part 41 from being caught around the fastening fixing holes 32A and 32B without being aligned with the shaft passage grooves 32B and 33B, and the crimping pin 40 being pulled out without being broken. it can.
Here, since the twisting portion 41 does not come off from the shaft passage grooves 32B and 33B, the line connecting the twisting portion 41 itself and the ends of the two elastic pieces of the twisting portion 41 on the head side is short. If the caulking pin 40 is formed so as to be inclined at a predetermined angle with respect to the hand direction, it is not necessary to form the pin guide portion 13 at an angle. However, it is more difficult to form the caulking pin 40 in such a shape than in the present embodiment because of the manufacturing method, and it is better to form the pin guide portion 13 in the cover case 10 by tilting it. Since it is easy to manufacture, the configuration as in this embodiment is optimal.

On the other hand, if the shaft passing grooves 32B and 33B are formed obliquely so that the twisting portion 41 can be locked while avoiding the shaft passing grooves 32B and 33B, the pin guide portion 13 does not need to be formed inclined. However, when removing the debris of the sealed portion from the fixing plate 31, it is difficult to extract it obliquely. Therefore, the configuration as in the present embodiment is optimal.
Incidentally, the substrate case 1 from which the first sealing portion 4A has been separated can be fixed to the base member 2 again using the second sealing portion 4B. In the state where the first sealing portion 4A is removed, the openings 12A and 22A (see FIG. 7) for allowing the fixing plate 31 provided on the upper surface of the second sealing portion 4B to pass through are exposed, but the base is fixed. When it is fixed to the part 30, the insertion piece 34 is positioned so as to cover it from the upper side, so that no foreign matter enters from the openings 12A and 22A to access the caulking pin 40, and there is a risk of dust and the like entering. Absent. The procedure for sealing and releasing the seal of the second sealing portion 4B is substantially the same as that of the first sealing portion 4A described above, but the second sealing portion 4B remaining on the base fixing portion 30 is moved downward and crimped. The engagement between the shaft portion 42 of the 40 and the pin hole 33 is released.

In the present embodiment, since the substrate case 1 is removed by moving it toward the front side with respect to the base member 2, the shaft passage grooves 32B and 33B are provided above and below the fixed plate 31. However, when the substrate case 1 is removed by moving it up and down with respect to the base member 2, the shaft passage grooves 32B and 33B may be formed forward from the fixing holes 32A and 32B.
Here, the details of the case sealing portion 3 are not particularly illustrated, but have substantially the same configuration as the base sealing portion 4. That is, as shown in FIG. 1, the case sealing portion 3 includes a first sealing portion 3A and a second sealing portion 3B, and each sealing portion includes a cover case caulking box 11 and a main body case 20 of the cover case 10, respectively. The main body case caulking box 21 (see FIG. 4) is fitted together. Moreover, it is integrated with the substrate case 1 by a plurality of severable connecting portions. Then, by attaching a caulking pin (not shown) similar to the caulking pin 40 shown in FIG. 3 from the side of the sealing portion, the cover case caulking box and the body case caulking box are caulked, and the caulking pin is destroyed. In other words, the cover case 10 is formed so as not to be removed from the main body case 20 unless the sealed seal portion is separated from the substrate case 1.

However, in the case sealing part 3, only the cover case caulking box 11 and the main body case caulking box 21 are caulked, and things such as the fixing plate 31 are not inserted, so the base sealing part 4 has The insertion gap 26 is not provided. Further, when releasing the seal, it is only necessary to separate the seal portion from the substrate case 1, so that it is not necessary to incline and fix the crimp portion of the caulking pin. Therefore, as shown in FIG. 2, the pin guide portion of the case sealing portion 3 is formed with the front-side open portion facing the front.
(Seal seal part 5)
Details of the seal seal 5 will be described with reference to FIGS. 11 to 13. Here, FIG. 12 is a cross-sectional view of the seal seal portion 5, and the upper side in the drawing is the front side. 13 (A) and 13 (B) are longitudinal sectional views of the seal seal portion 5, and the left side is the front side in the drawing. FIG. 13C is a partial cross-sectional view of the seal seal portion 5.

As shown in FIG. 11, the seal seal part 5 is not removable to the sticking base 50, the sticking part 15 provided on the lower right side of the substrate case 1, the sticking base 50 fixed to the sticking sticking part 15, and the sticking base 50. And an IC tag seal 70 as a seal seal pasted across the seal pasting part 15 and the pasting base 50.
The seal sticking portion 15 is provided on the left and right sides of the concave portion 15A formed in the concave lower surface of the concave portion 15A, the concave portion 15A recessed from the front side of the substrate case 1 (cover case 10), and the concave portion 15A. Affixing surface 15C. The recess 15A has a side wall and an upper wall, a square hole 19 is provided in the upper wall of the recess 15A, and the bottom is open. That is, the recess 15A has open portions on the upper side and the lower side. As shown in FIG. 12, the screw hole 15B matches the screw hole of the screw boss 27 (see FIG. 4) provided in the back plate 20A of the main body case 20. The sticking surface 15C is substantially flush with the front surface of the cover case 10, and is used to clearly indicate the sticking area of the IC tag seal 70 by a mark line or a slight dent or a slight protrusion that matches the width of the IC tag seal 70. is there.

  The sticking base 50 is a vertically long sticky plate 51 fitted in the recess 15A, a screw boss 52 provided substantially at the center of the sticking plate 51, and protrudes from the lower end of the sticking plate 51 to the back side and protrudes. And a folded piece 53 that is bent from the end and extends upward. A convex portion 51A that protrudes upward is provided at the upper end portion of the sticking plate 51, and a rectangular shape is provided near the upper end portion of the sticking plate 51 and below the convex portion 51A and near the lower end portion of the sticking plate 51. A locking opening 54 is provided. The convex portion 51A can be inserted into the square hole 19 provided in the upper wall of the concave portion 15A of the seal attaching portion 15 (see FIG. 13A). As shown in FIG. 12, the screw hole 52A of the screw boss 52 matches the screw hole 15B when the sticking base 50 is installed at an appropriate position of the seal sticking portion 15. Further, as shown in FIG. 13B, the folded piece 53 is formed by sandwiching the joint between the lower end portion of the cover case 10 and the lower end portion of the main body case 20 between the sticking plates 51. It plays the role which fixes a lower end part. A convex portion 53A that protrudes upward is provided at the upper end portion of the folded piece 53, and can be inserted from below into a square hole 28 (see FIG. 4) provided in the bottom surface 20C of the main body case 20. The locking opening 54 is for fixing the seal cover 60. The sticking table 50 is fixed to the screw boss 27 provided on the main body case 20 via the sticker sticking portion 15 with a screw Q.

  As shown in FIG. 11, the seal cover 60 is a transparent member, and has a flat plate-shaped covering portion 61, a breaking opening 62 provided at a substantially central portion of the covering portion 61, and a front portion around the breaking opening 62. A leg-equipped lid 63 that covers the destruction opening 62 from the front side, and a latching claw 64 that is provided at the upper and lower ends of the covering portion 61 and projects to the back side. ing. The covering portion 61 is for covering and protecting the IC tag seal 70 attached to the sticker attaching portion 15 and the attaching stand 50 from the front side. When the seal cover 60 is fixed to the affixing base 50, the breaking opening 62 matches the screw boss 52 as shown in FIG. The legged lid 63 can be removed from the seal cover 60 by cutting the leg part 63A. As shown in FIG. 11, the locking claw 64 has two thin plate members each having a claw portion on the protruding side, which are arranged in parallel so that the plate surface is in the left-right direction and the claw portions are opposed to each other. Once the locking claw 64 is attached to the locking opening 54 of the sticking base 50, it cannot be removed from the sticking base 50 unless the engagement between the claw portion and the locking opening 54 is released from the back side of the sticking base 50. The covering portion 61 is formed with two slits 65 parallel to the vertical direction (vertical direction) with the legged lid 63 interposed therebetween. As shown in FIGS. 12A and 12B, the installation interval between the two slits 65 matches the left and right widths of the sticking plate 51 when the sticking base 50 is attached to the recess 15A of the sticker sticking part 15. It has become. The width of each slit 65 is substantially the same as the groove formed by the side surface of the adhesive plate 51 and the side wall of the concave portion 15A (the joint between the concave portion 15A and the adhesive plate 51) when the adhesive base 50 is attached to the concave portion 15A. The slits 65 are formed to have a matching width, and the vertical length of each slit 65 is substantially the same as or slightly longer than the vertical length of the IC tag seal 70.

The IC tag seal 70 is an adhesive sheet formed of paper, plastic film, or paper coated with plastic, and has predetermined information written on the front surface and an adhesive surface on the back surface. Further, an IC chip 71 (see FIG. 12) storing predetermined identification information is fixed on the back surface, and an antenna wire is laid. The information on the IC chip 71 is contactless by a predetermined reader. It can be read. Further, the entire back surface of the IC tag seal 70 is covered with a release sheet (not shown), and the release sheet is peeled off and attached in use.
(Seal seal seal 5 and seal release)
The sealing procedure of the seal sealing unit 5 having the above configuration will be described.

  First, the sticking base 50 is fitted into the lower opening of the recess 15A of the seal sticking part 15. Then, it slides upward. When the sticking base 50 is pushed in until the screw hole 52A matches the screw hole 15B of the seal sticking part 15, the convex part 51A of the sticking plate 51 enters the square hole 19 as shown in FIGS. 13 (A) and 13 (B). The convex portion 53A of the folded piece 53 enters the square hole 28. At this time, as shown in FIG. 13A, the protruding portion 51B formed at the rear of the convex portion 51A comes into contact with the upper wall of the concave portion 15A from below to close the square hole 19, and FIG. As shown, an overhang 53B formed behind the convex portion 53A comes into contact with the bottom surface 20C of the main body case 20 from below to close the square hole 28. Further, the folded piece 53 sandwiches the lower end portions of the cover case 10 and the main body case 20. Furthermore, as shown in FIG. 12, the sticking surface 15C of the seal sticking portion 15 is flush with the front face of the sticking plate 51, and between the side wall portion of the recess 15A and the side end portion of the sticking plate 51. There is a slight gap. Further, the screw hole 52A of the screw boss 52 matches the screw hole 15B of the seal attaching portion 15. Then, by screwing the screw Q into the screw hole 52A, the screw Q is finally screwed into the screw hole of the screw boss 27 of the main body cover, and the sticking base 50 and the seal sticking portion 15 are fixed to the main body cover 20. As shown in FIG. 12, the head of the screw Q is completely hidden behind the screw boss 52, so that it does not protrude from the front surface of the sticking plate 51.

Next, the IC tag seal 70 is pasted so as to straddle the pasting surface 15C and the front surface of the pasting plate 51 that is flush with the pasting surface 15C. The IC tag seal 70 covers the screw boss 52 and the screw Q cannot be removed unless the IC tag seal 70 is broken. Since the IC tag seal 70 has a length in the vertical direction that is shorter than the length between the upper and lower locking openings 54 provided on the sticking plate 51, the IC tag seal 70 does not block the locking opening 54. . When the IC tag seal 70 is affixed at an appropriate position, the IC chip 71 exactly matches the position of the screw boss 52.
Finally, the seal cover 60 is fixed to the sticking table 50. That is, the latching claw 64 is pushed into the latching opening 54 to make it fit (see FIG. 13C). As described above, the engagement claw 64 and the engagement opening 54 can be released only from the back side of the affixing base 50, and the affixation base 50 must be removed from the screw Q covered by the IC tag seal 70. It cannot be removed from the sticker 15. Therefore, the seal cover 60 cannot be removed from the sticking table 50 unless the seal cover 60 is destroyed. That is, the seal cover 60 is sealed by the locking claws 64. Here, as shown in FIG. 12, the lid 63 with legs of the seal cover 60 is located in front of the screw Q, and there is a gap between the legs 63A of the lid 63 with legs. It is a gap for inserting a nipper when destroying the lid 63 with legs, and even if a screwdriver is inserted through this gap, the screw Q cannot be accessed and the screw Q cannot be removed without destroying the lid 63 with legs. It has become. Note that the entire IC tag seal 70 can be visually recognized from the cover plate portion 61. Further, as shown in FIG. 12, the slit 65 is located at a position matching the gap between the side wall portion of the recess 15 </ b> A and the side end portion of the sticking plate 51. Although not shown, an IC chip antenna is located directly behind the slit 65.

  Next, when releasing the seal of the seal seal portion 5, as shown in FIG. 12B, the leg-attached lid 63 of the seal cover 60 is removed by cutting the leg portion 63A. Then, a driver (not shown) is pierced from the opened breaking opening 62 to break the IC tag seal 70, reach the head of the screw Q, and remove the screw Q. At this time, the IC chip 71 located on the back side of the IC tag seal 70 and in front of the screw Q is also destroyed and cannot be reused. Then, the sticking base 50 can be removed from the sticking sticking portion 15 by pulling the sticking base 50 with the seal cover 60 fixed downward. However, the IC tag seal 70 is stuck across the sticking surface 15C of the sticking sticking portion 15 and the front face of the sticking plate 51, and not only the adhesive surface has to be moved in the horizontal direction but also the IC chip 71 on the seal back surface. Since the antenna wire is laid, it may be difficult to tear it off, and in some cases, the sticking base 50 may not be pulled out. Therefore, if the IC tag seal 70 is cut in the longitudinal direction with a cutter knife or the like through the slit 65 of the seal cover 60, the sticking base 50 can be easily pulled out. Since the back side of the slit 65 is a gap between the concave portion 15A and the sticking plate 51, the work of inserting the knife and cutting the IC tag seal 70 can be performed easily and reliably.

  As described above, the seal sealing unit 5 according to the present embodiment attaches the IC tag seal 70 to the affixing base 50 detachably attached to the substrate case 1 and covers the surface with the seal cover 60 to protect the IC tag seal 70. The cover 60 is formed so as not to be removable from the outside. Therefore, it is possible to prevent the IC tag seal 70 from being illegally replaced. Further, since the affixing base 50 is fixed to the main body cover 20 with the screws Q, the screws Q must be removed when the substrate case 1 is opened. Since the IC tag seal 70 must be destroyed in order to remove the screw Q, a trace always remains when the substrate case 1 is opened illegally. Further, since the IC chip 71 is aligned with the position of the screw Q, the IC chip 71 is destroyed when the screw Q is removed, and the function is not performed. As a result, only the IC chip 71 can be removed from the IC tag seal 70 that has been illegally peeled off and cannot be used illegally.

In addition, the sticking base 50 has a folded piece 53 as a case fixing portion, so that it can be used to reinforce fixing of the cover case 10 and the main body case 20, and the sticker and seal cover 60 attached to the sticking surface 15C. Can be reused.
In the present embodiment, the attaching base 50 is formed so as to be mounted from the bottom surface portion of the substrate case 1, but it may be mounted from the top surface portion or the left and right side portions. Alternatively, the sticking table 50 may be fitted from the front side into a recess whose periphery is closed.
(Switch cover 80)
As shown in FIGS. 1, 2, and 4, the switch cover 80 is a box-shaped cover that covers the operation switch 110 that can be operated from the front side of the substrate case 1 and that is open on the back side. Details of the switch cover 80 will be described below with reference to FIGS. Here, FIG. 14A is a front view of the switch cover 80, and FIG. 14B is a partial left side view of the switch cover 80. In FIG. 14B, the right side is the front side in the drawing. 15A and 15B are a partial front view of the switch cover 80 and a partial left side view of the switch cover 80, respectively. FIG. 16 is a cross-sectional view of the switch cover 80, and the upper side in the drawing is the front side. 16A is a cross-sectional view taken along line II-II and III-III in FIG. 15, and FIG. 16B is a cross-sectional view taken along line II in FIG.

  As shown in FIG. 14A, the switch cover 80 has a front plate 80A and four side plates 80B to 80E, and protrudes vertically on the left side end portions of the upper side plate 80D and the lower side plate 80E. A provided shaft stop pin 81 is provided. The shaft locking pin 81 is locked to the bearing 16 formed on the cover case 10 of the substrate case 1 so that the shaft locking pin 81 is supported by the cover case 10 so as to be rotatable in the front-rear direction around the shaft locking pin 81. Is. A spring fixing shaft 82 for mounting the spring 90 is provided on the left side plate 80B of the switch cover 80. Then, by attaching the spring 90 to the spring fixing shaft 82 and attaching it to the cover case 10, the spring 90 is always urged in the closing direction (direction rotating backward).

As shown in FIGS. 1 and 2, the switch cover 80 covers a part of the seal seal portion 5 in a closed state. Specifically, a part of the upper end side of the slit 64 of the seal cover 60 is covered with the switch cover 80. For this reason, the operation of cutting the IC tag seal 70 through the slit 64 to release the seal of the seal seal portion 5 can be performed only when the switch cover 80 is opened or removed.
The spring 90 is a torsion coil spring including a coil part 91, a first arm part 92 extending from one end part of the coil part 91, and a second arm part 93 extending from the other end part of the coil part 91. The coil portion 91 is fitted and attached to the spring fixing shaft 82 so that the portion 93 faces the outside of the cover and the first arm portion 92 faces the inside of the cover. The spring fixing shaft 82 is a columnar shaft that protrudes in parallel with the side surface of the switch cover 80 from a bracket B provided on the side plate 80B of the switch cover 80. A predetermined gap is formed between the side surface of the spring fixing shaft 82 and the side plate 80B of the switch cover 80 so that the coil portion 91 can be fitted from above. The spring 90 is attached to the spring fixing shaft 82 so that the second arm portion 93 is positioned on the lower side. When the switch cover 80 is fixed to the substrate case 1, the second arm portion 93 is locked to a spring stopper 17 formed on the cover case 10. Specifically, as shown in FIG. 4, the spring stopper 17 has a groove portion 17A surrounded by standing walls provided on the top and bottom and the left side of the front plate 10 of the cover case 10, and as shown in FIG. By positioning the second arm portion 93 so as to extend from the right opening to the inside of the groove portion 17A, the second arm portion 93 cannot move in the vertical direction inside the groove portion 17A.

In the side plate 80B of the switch cover 80, an opening 83 for inserting the first arm portion 92 of the spring 90 inside the cover is formed. As shown in FIG. 14 (B), the opening 83 is formed in a substantially parallelogram that is vertically long when viewed from the side, and the rear end face 84 located on the back side and the front end face 85 located on the front side are: As it goes down, it inclines so that the distance from the front decreases. Further, a locking groove 86 having a U-shaped side view as viewed from the side is provided at the lower end portion of the rear end face 84, which is formed by recessing the rear end face 84 one step rearward. The spring 90 is held at a position above the bracket B when the first arm portion 92 enters the locking groove 86 and is attached to the switch cover 80.
Here, as shown in FIG. 14B, the relationship between the opening 83 and the spring fixing shaft 82 is that the upper end x of the rear end face 84 and the groove bottom z of the locking groove 86 are spring-like when viewed from the side. The lower end y of the rear end face 84 is located on the front side of the central axis X, and is located on the rear side of the central axis X of the fixed shaft 82. Further, the upper end portion x of the rear end face 84 and the groove bottom portion z of the locking groove 86 are formed so that the distance from the central axis X is substantially the same. Further, the spring fixing shaft 82 is longer than the entire length of the spring 90, and is formed so that its tip is located above the upper end of the locking groove 86 when viewed from the side. When the second arm portion 93 reaches the bracket B that supports the spring fixing shaft 82, the first arm portion 92 enters the locking groove 63 and is locked until the first arm portion 92 is once moved forward. The first arm portion 92 is prevented from coming out of the locking groove 63.

(Removal of switch cover 80)
Next, a procedure for attaching the switch cover 80 having the above configuration to the substrate case 1 will be described.
First, the spring 90 is attached to the switch cover 80. As shown in FIG. 15A, in the state where one first arm portion 92 of the spring 90 is placed in the opening 83 and the other second arm portion 93 is positioned on the spring fixing shaft 82 side, 91 is inserted into the spring fixing shaft 82. The first arm portion 92 passes through the back side of the spring fixing shaft 82 and reaches the opening 83. As shown in the figure, in a state where the lower end portion of the coil portion 91 is applied to the tip end portion of the spring fixing shaft 82, the first arm portion 92 is located on the upper end portion x (see FIG. 14B) side of the rear end face 84. positioned. At this time, the outer edge 84A (see FIG. 16A) of the rear end face 84 where the first arm portion 92 is located is the boundary between the rear end face 84 and the locking groove 86 (the rear end face in FIG. 14B). As shown by a two-dot chain line in FIG. 16A, in the normal state of the spring 90 (the state where no tension is applied), the first arm portion 92 is on the back side of the edge 84A of the lower end portion y) of 84. The front end surface 85 is not in contact with the edge 84A of the rear end surface 84. However, even in this position, when the second arm portion 93 is rotated in the direction of the switch cover 80 (right side in the front view), the coil portion 91 rotates around the spring fixing shaft 82 and the first arm portion 92 is moved. The base side (coil portion 91 side) is away from the rear end surface 84, and the tip side (projection side) is in contact with the front end surface 85. Here, when the spring 90 is in the position shown in FIG. 15A, the state in which the first arm portion 92 is in contact with the rear end surface 84 and not in contact with the front end surface 85 is defined with respect to the spring fixing shaft 82 of the spring 90. As an initial position (initial angle) in the rotation direction, description will be made assuming that the coil portion 91 is fitted into the spring fixing shaft 82 while maintaining the initial angle.

When the spring 90 is moved downward (bottom side) from the state of FIG. 15A, the first arm portion 92 has an edge 84A of the rear end face 84 that is inclined so as to gradually protrude toward the front as it goes downward. It will be displaced from the original position. Specifically, the first arm portion 92 rotates so as to be pushed out to the front side as it approaches the locking groove 86. That is, when pinching the spring 90 with a finger and inserting the second arm part 93 into the spring fixing shaft 82 without moving from the initial position, the coil part 91 is gradually moved according to the behavior of the first arm part 92 described above. The tension in the torsional direction is applied.
As shown in FIG. 15B, when the first arm portion 92 is located near the lower end portion y of the rear end face 84 (that is, the position immediately before the locking groove 86), the solid line in FIG. As shown, the tip side (protrusion side) of the first arm portion 92 abuts on the inner edge 85A of the front end face 85. At this time, even if the hand is released from the spring 90, the spring 90 is held in that position. In this state, the outer peripheral surface of the spring fixing shaft 82 and the inner peripheral surface of the coil portion 91 are in close contact, and the spring 90 is temporarily locked between the spring fixing shaft 82 and the opening 83. That is, the spring 90 is sandwiched between the spring fixing shaft 82 and the edge 85A. Therefore, when the spring 90 is in the position shown in FIG. 15B, the spring 90 is difficult to come off from the spring fixing shaft 82.

  Now, as shown in FIG. 14 (B), the first arm portion 92 is moved backward by pushing the spring 90 in the position of FIG. 15 (B) into the spring fixing shaft 82 against the temporary locking force. It gets over the lower end y of the end face 84 and enters the locking groove 86. Here, as described above, the groove depth of the locking groove 86 is formed so as to be equal to the upper end portion x of the rear end face 84, that is, the position where the first arm portion 92 is not subjected to tension. Therefore, no pressure is applied to the spring 90 in a state where the first arm portion 92 is positioned in the locking groove 86. That is, the relationship between the coil portion 91 and the spring fixing shaft 82 is free. Therefore, when a forward force is applied to the first arm portion 92, the coil portion 91 rotates around the spring fixing shaft 82, and the first arm portion 92 moves from the groove bottom portion z of the locking groove 86 to the front end surface. Move in the direction of 85. However, even if the entire spring 90 is moved in the axial direction, that is, the direction in which the spring 90 is pulled out from the spring fixing shaft 82, the first arm portion 92 is hooked on the standing wall 68B (see FIG. 16B) of the locking groove 86. Does not naturally come off the spring fixing shaft 82. In this way, the spring 90 is attached to the switch cover 80. In order to pull out the spring 90 from the spring fixing shaft 82, the first arm portion 92 is formed at the base portion of the first arm portion 92 so that the first arm portion 92 gets over the lower end portion y of the rear end face 84 and escapes from the locking groove 86. What is necessary is just to curve by applying the force to an outer side direction.

  The method of attaching the spring 90 to the switch cover 80 is not limited to the method described above. For example, the spring 90 may be dropped from above in a state where the tip of the spring fixing shaft 82 is on the upper side. In this case, if the spring 90 is released when the spring 90 is in the initial position, the spring 90 is moved by the above-described behavior of the first arm portion 92 (displaced from the original position by being pushed by the edge 84A of the rear end face 84). The whole falls down while rotating around the axis. When the first arm portion 92 is dropped to the position immediately before the locking groove 86, the first arm portion 92 contacts the edge 85A of the front end face 85 and the spring 90 cannot rotate. As a result, tension is applied to the coil portion 91, and the spring 90 stops at that position. That is, even when the spring 90 is naturally dropped on the spring fixing shaft 82, the spring 90 can be temporarily locked at a position immediately before the locking groove 86. Thereafter, similarly to the above, the spring 90 is attached to the switch cover 80 by further pushing the spring 90 against the temporary locking force into the spring fixing shaft 82.

  The switch cover 80 to which the spring 90 is mounted as described above engages the shaft retaining pin 81 with the bearing 16 while the second arm portion 93 is positioned in the groove portion 17A formed in the spring retaining member 17. Here, the portion of the switch cover 80 in which the upper shaft locking pin 81 is formed is bent upward and downward by applying pressure. Therefore, both the upper and lower shaft locking pins are bent in a state where the portion is bent. Each 81 can be engaged with the bearing 16. When the switch cover 80 is pivotally attached to the cover case 10 in this way, the spring 90 is rotated by the second arm portion 93 rotating in the direction of the arrow α as shown in FIG. The first arm 92 receives a repulsive force in the direction of arrow β, and the first arm 92 presses the outer edge 86A of the groove bottom z (see FIG. 14B) of the locking groove 86. Thus, the switch cover 80 is urged in the direction to be always closed. When the switch cover 80 is removed from the board case 1, the portion where the upper shaft locking pin 81 is formed is bent to disengage the shaft locking pin 81 from the bearing 16.

  As described above, the switch cover 80 according to the present embodiment is attached to the substrate case 1 with the spring 90 attached, so that the spring 90 is detached from the fixed portion and dropped or flies during attachment / detachment. There is no need to go. In the present embodiment, the fixing portion (spring fixing shaft 82 and opening 83) for fixing the spring 90 is tensioned immediately before the spring 90 reaches the fixing position, and is temporarily locked to the fixing portion. It is formed so that. Therefore, in particular, when removing the spring 90 from the switch cover 80, the spring 90 to be removed from the fixed position will not unintentionally fall out or jump out. There is no need to pay. For this reason, the assembly work efficiency of the substrate case 1 can be increased. Further, when the spring 90 is attached to the switch cover 80, the spring 90 can be temporarily locked to the fixing portion before reaching the fixing position, so that the spring 90 can be prevented from falling off or jumping out.

  In the present embodiment, the rear end surface 84 of the opening 83 is formed so as to incline toward the locking groove 68, but the first arm portion 92 is formed on the rear end surface 84 by the locking groove 68. Any shape that allows tension to be applied to the coil portion 91 when it is positioned immediately before is acceptable. For example, as shown in FIG. 17A, the opening 83 is rectangular, the rear end face 84 is formed to be inclined outward, and the position of the edge 84A becomes closer to the groove bottom z as it approaches the locking groove 68. You may make it leave | separate (refer FIG. 17 (B) which is the IV-IV sectional view of FIG. 17 (A)). Alternatively, as shown in FIG. 17C, a protrusion 87 that gradually protrudes to the front side is provided in the vicinity of the lower end portion of the rear end surface 84, and a gap between the upper end portion of the protrusion 87 and the lower end surface of the opening 83 is provided. May be formed as a locking groove 68. In this case, the rear end face 84 and the groove bottom z of the locking groove 68 may be in a straight line.

The locking groove 68 is formed in a square shape that is recessed backward by one step from the rear end face 84 as the spring guiding portion of the opening 83, but the first arm portion 92 enters the locking groove 68. As long as the spring 90 can be attached to the cover case 80, any shape may be used. For example, although not particularly illustrated, a groove inclined obliquely rearward from the lower end portion y of the rear end surface 84 as a temporary locking portion, or a groove notched in an L shape may be used.
Further, in this embodiment, the shaft locking pin 81 and the spring fixing shaft 82 are provided separately, but the shaft portion on which the spring 90 is mounted is formed so as to also serve as the rotation shaft of the switch cover 80. Also good.
In the present embodiment, the switch cover 80 that covers the operation switch 110 provided on the substrate case 80 is provided. However, the substrate case 1 may be other than the operation switch 100, such as a caulking portion or a sealing portion. An open / close cover may be provided. Also in this case, the assembly of the substrate case 1 can be facilitated by using the same structure as described above.

Furthermore, the configuration of the switch cover 80 in the present embodiment can be applied to other than the substrate case 1. For example, you may use for the cover etc. which cover the setting change switch etc. which were provided in the front of the power supply box.
(Summary)
As described above, in the present embodiment, the base seal portion 4, the seal seal portion 5, and the cover case 80 are configured as described above, so that the trace of seal release is clarified and security is improved. Assembly and disassembly can be performed easily. Further, since the trace of the opening of the substrate case 1 remains not only by the case sealing portion 3 but also by the seal sealing portion 5, the security of the substrate case 1 can be further enhanced. Further, since the cover case 80 covers a part of the seal seal portion 5, it is difficult to perform the work for releasing the seal of the seal seal portion 5, and there is an effect that the unauthorized seal release is not easily performed. .

  The present invention can also be used for a slot machine that is not a separation type slot machine. In this case, it is needless to say that the base member 2 can be fixed to the inner surface of the housing of the slot machine, for example, the back plate, and the substrate case 1 can be fixed to this. It is also possible to form a base fixing part similar to that of 30 and allow the housing itself to function as a base. Further, the present invention may be used for gaming machines other than slot machines, for example, pachinko gaming machines.
