Description

  The present invention relates to a gaming machine that employs a housing sealing structure at an opening portion of a control box.

In gaming machines such as pachinko machines, a housing sealing structure is employed so that a control box that can be opened and closed cannot be easily opened or closed in order to prevent unauthorized modification.
Conventionally, what is shown in FIG. 17 and FIG. 18 is known as this kind of enclosure sealing structure.

In the figure, a housing made up of a resin lid 1 and a housing body 2 is a control box. Four enclosure sealing structures are formed at the opening edge of the control box. The casing sealing structure includes a protruding piece 1a on the lid 1 side and a nut holding portion 2a on the casing body 2 side.
As shown in FIG. 18, the protruding piece 1a is formed with a through hole 1a1 through which the screw 3 passes. The shaft portion of the screw 3 is formed with a male screw portion 3b only at the tip, and is an extension portion 3a in which no male screw is formed. On the other hand, a cylindrical insert nut 4 having a female screw portion 4a formed on the inner peripheral surface is fitted into the nut holding portion 2a, and the length of the insert nut 4 is generally slightly shorter than the extension portion 3a. In addition, a donut-shaped leaf spring member 5 is inserted further into the insert nut 4.

  In the above configuration, when the lid body 1 is aligned with the housing body 2 and the protruding piece 1a and the nut holding portion 2a overlap, the screw 3 is inserted into the through hole 1a1 of the protruding piece 1a, Screwed into the insert nut 4. When the screw 3 is rotated, the male screw portion 3b is screwed into the female screw portion 4a of the insert nut 4, but since the extension portion 3a is formed on the screw 3, the male screw portion 3b is formed at a certain point. The part 3b penetrates the insert nut 4. Further, when threaded, the male screw portion 3 b also penetrates the leaf spring member 5 and is biased in the back direction by the leaf spring member 5. And the state immediately after penetration will be the state by which the housing main body 2 and the cover body 1 were sealed.

  After this, even if the screw 3 is rotated in the reverse direction to remove the lid 1 from the housing body 2, the male screw portion 3 b is biased in the back direction by the leaf spring member 5. It does not screw into the female screw part 4a. For this reason, the screw 3 cannot be removed, and the lid 1 cannot be removed from the housing body 2. The only way to open as needed is to break either or both of the resin protruding piece 1a and the nut holding portion 2a. In the case of the illustrated control box, four pairs of enclosure sealing structures are provided, which corresponds to the case where maintenance is required and opening is required.

In the conventional housing sealing structure described above, the screw is screwed into the nut, so a tool such as a screwdriver is essential and workability is not good. On the other hand, it is fixed by pushing operation to improve workability. When doing so, there was a problem that fraud countermeasures were difficult .
The present invention has been made in view of the above problems, and an object of the present invention is to provide a gaming machine that employs a casing sealing structure that can easily prevent fraud without degrading workability.

To achieve the above object, the invention according to claim 1, the opening of the box body to be controlled box closed by a lid, the sealed using the operation member and the lid member and the front Symbol box body a game machine employing the housing sealing structure, wherein the casing body and the lid, a configuration having a slide surface facing the case of closing the opening portion by sliding each other, before Kikatami body on one member of the body and the lid member fixed receiving structure for sealing is formed, when the other members of closing the opening, the operating member to the stationary receiving structure and phase opposing position holding unit for holding is formed, said wall inwardly to form an opening of the fixed receiving structure is provided, wherein the operating member is engageable secured across the slide surface for the previous SL stationary receiving structure It is held in Do position, the fixed receiving formation Contact Wherein it is engaged with and fixed to the fixed receiving structure while being sandwiched between the double wall formed by finely the wall.

As described above, the present invention is held by the holding portion formed on the other of the casing main body and the lid body with respect to the fixed receiving structure formed on one of the casing main body and the lid body. Since the operation member is engaged and fixed in a state of being sandwiched between the double wall surface formed by the fixed receiving structure and the wall portion, a casing capable of easily preventing fraud without deteriorating workability A gaming machine employing a sealing structure can be provided.

The present invention may be configured Nde including the following means.
Mean 1
Various configurations can be adopted as the configuration on the side that holds the resin operation element. As an example, the resin operation element on the side that holds the resin operation element in the housing body and the lid body is used. It is good also as a structure which has the operation element holding | maintenance part which formed the recessed part which hold | maintains so that linear movement is possible in a predetermined range, and the through-hole which lets the said metal engagement piece pass is formed in the back wall of the said recessed part.

  In the invention configured as described above, the resin operating element may be held by either the casing body or the lid, but an operating element holding part is formed on the holding side. The resin-made operating element can be linearly moved within a predetermined range within a recess formed in the operating element holding part. Further, when the resin operation element is inserted into the recess, the metal engagement piece held by the resin operation element passes through a through hole formed in the back wall of the recess and protrudes to the opposite side.

That is, when the resin operating element is inserted into the recess of the operating element holding part from the side of the metal engaging piece, the metal engaging piece projects through the through hole to the opposite side, and the resin operating element Since the child itself can move linearly within a predetermined range, the above-described pushing operation is possible.
Mean 2
A configuration may be adopted in which the inner peripheral shape of the concave portion of the operating element holding portion and the outer peripheral shape of the resin operating element substantially coincide.
In the invention configured as described above, since there is no gap between the recess and the resin operation element, it is not possible to push in the foreign matter and pull out the resin operation element.

Mean 3
In this case, the inner circumferential shape of the concave portion may be a tapered shape in which the opening shape becomes narrower toward the back, and the resin operation element may have a tapered shape having an inclined surface substantially coinciding with the tapered shape.
In the invention configured as described above, the resin-made operating element before the pressing operation is held in the recess with a sufficient gap, and the pressing operation is easy. Then, as the push operation is performed, the resin operation element enters the recess, and there is no gap, so that it is difficult to pull out by the foreign matter.

Mean 4
The metal engaging piece and the fixed receiving structure are configured such that a metal engaging piece that is moved by a pressing operation together with a resin operation is pressed and engaged with the fixed receiving structure side. Various structures can be adopted. As an example, the metal engagement piece is formed by folding the metal plate member tip at an acute angle, and the fixed receiving structure is pulled out after passing while bending the folded end of the metal engagement piece. It is good also as a structure which has the slit made impossible.

  In the invention configured as described above, a slit is formed in the fixed receiving structure, and the metal engagement piece formed by folding the tip of the metal plate material at an acute angle is pushed into the slit. Sometimes the folded end of the metal engagement piece bends and passes, but even if you try to pull it out in the opposite direction, the bent folded end is already open to the original angle, so the opening of the slit It hits the edge. Further, since the folded end is folded at an acute angle, the folded end is firmly engaged with the opening edge and is difficult to come out.

Mean 5
Although the metal engagement piece is held by the resin operation element, it is possible to make it difficult to come off with a simple structure. For example, the metal engagement piece is formed in a U shape as a whole, and is formed by folding back the tips at both ends, and the fixed receiving structure is formed such that the slit is formed substantially in parallel and the insertion side in the slit A tapered inclined surface that guides the tip of the metal engagement piece is formed at the opening end of the metal, and an acute corner that faces the folded end of the metal engagement piece is formed at the opposite opening end. It is good also as the structure which carried out.

  In the invention configured as described above, the metal engagement piece is formed in a U shape as a whole, and is formed by folding back the tips at both ends. Engage with the structure. That is, since the metal engagement piece itself is fixed to the other side, there is no need to hold it with the resin operation element. Here, in the fixed receiving structure, the slits are formed substantially in parallel so that they can be engaged with both ends of a U-shaped metal engagement piece. In addition, since the tapered inclined surface is formed at the opening end on the insertion side of the slit, the tip of the metal engagement piece can be correctly guided to the opening of the slit, and a metal made through the slit Since the folded end of the engagement piece faces an acute corner formed at the opening end on the opposite side of the slit, the two bite firmly into each other and are difficult to come off.

Mean 6
As an example of making it difficult for the folded end to come off, the metal engagement pieces may be formed by alternately folding the tips in opposite directions.
In the invention configured as described above, the tips of the metal engagement pieces are alternately folded back in opposite directions, so that one folded end does not bite into the opening end of the slit. If an attempt is made to push and pull out, the folded end folded back to the opposite side will tend to bite into the opening end, making it difficult to pull out.

Mean 7
As an example of preventing the resin operation element itself from falling off the operation element holding part, the metal engagement piece can be temporarily supported in a state of passing through the through hole of the recess in the operation element holding part. It is good also as a structure which has a convex part.
In the invention configured as described above, since the convex portion formed on the metal engagement piece can be temporarily supported in a state of passing through the through hole of the concave portion in the operating element holding portion, the resin operating element does not fall off.

Mean 8
If such a housing sealing structure is adopted, once sealed, it cannot be opened again. Moreover, there is a risk of damaging the case itself by applying excessive force to the case itself. In order to eliminate such a problem, the operation element holding part may be connected by a breakable connecting material so as to be separable from either the housing body or the lid.
In the invention configured as described above, the operating element holding portion is connected to either the casing main body or the lid body by a breakable connecting material. For this reason, by breaking the connecting material, the operating element holding portion is originally connected to the housing main body or the lid body while the resin operating element and the metal engaging piece are engaged and fixed to the fixed receiving structure. To separate. Therefore, the casing body and the lid can be opened.

Such a connecting material may be formed in a plate shape or a rod shape, for example, and can have various shapes. Of course, a groove may be cut out to make it easier to break at a certain place.
Mean 9
Moreover, as an example in the case of connecting with such a breakable connecting material, a plurality of the operation element holding portions may be arranged side by side via the connecting material.
In the invention configured as described above, on the premise that the casing body and the lid can be opened and closed again by breaking the connecting material, a plurality of operation element holding portions are arranged side by side through the connecting material. Therefore, it is easy to check the breaking condition when viewed from the front.

Mean 10
Here, the frequency of opening and closing may vary depending on the application. As a suitable example in such a case, the plurality of operation element holding portions are configured so that the number of the connecting members is different.
For example, on the premise that opening and closing is basically impossible, it is difficult to perform fraud if the initial sealing is most difficult to be illegitimately opened. Therefore, in such a thing, what is necessary is just to increase the number of the connection materials which connect the operation element holding | maintenance part sealed initially. Further, if the sealing is always opened twice when the inspection process or the like is performed, the number of connecting members for connecting the operation element holding portions used for the third sealing may be increased. Note that the number of connecting members in this case is the number that requires breaking when unsealing, and is sequentially counted so as not to include the number of wall members that have already been broken when breaking. .

Mean 11
The arrangement position of the connecting material is arbitrary, but if it is arranged on the back side of something with respect to the viewing direction from the outside, it is difficult to recognize the destruction. For example, assuming that the control box is disposed on the back side of the pachinko machine, the operation element holding portion may be located on the back side, and the connecting material may be disposed on the back side. In this case, when the pachinko machine is opened for maintenance, the connecting member on the back side of the pachinko machine cannot be visually recognized even if the operator holding part is visible. Therefore, even if the connection material is destroyed and some kind of fraud is added, it is difficult to detect the fraud by simply opening the pachinko machine.

Therefore, in order to cope with such a case, the shape of the connecting member may be changed and extended so as to avoid the obstacle to a position where it can be visually recognized from the outside.
In this way, even if the connecting material is placed on the back side of the obstacle, if the connecting material is destroyed in order to perform fraud, it is easy to find the destruction place from the front side, and the fraud can be visually confirmed. It becomes easy to do.
Mean 12
Various structures can be used for opening and closing the housing body and the lid. As an example, the lid is slid and attached to the housing body, and the operating element holding portion is attached to the housing body. The fixed receiving structure is formed on the lid body, and the operation element holding portion and the fixed structure face each other when the lid body is slid and mounted.

In the invention configured as described above, when the lid is slid and mounted, the fixed receiving structure formed on the lid and the operation element holding portion formed on the housing body face each other. Then, the resin operation element can be pushed and operated to engage and fix both.
Mean 13
The mode of facing each other when sliding may be such that they face each other in the sliding direction.
In this case, the operation in the sliding direction is resisted by the engagement force of the metal engagement piece.

Mean 14
When facing each other, it is possible to form a wall surface on one side of the operating element holding part or the fixed receiving structure that is inserted and overlapped with the other when facing each other to surround the metal engagement piece. is there.
As a result, a double wall surface is formed around the metal engagement piece when facing each other, and it is difficult to perform fraud such as removing the engagement portion of the metal engagement piece from the outside.
Mean 15
Other modes that face each other when sliding may be arranged along the sliding surface, overlap each other as they slide, and finally face each other.

In this case, the metal engagement piece crosses the slide surface and engages with the fixed receiving structure by the pushing operation.
Mean 16
At this time, a configuration may be adopted in which the resin-made operating element is stopped while partially crossing the slide surface.
In this case, since the resin-made operating element also serves to prevent the lid and the casing main body from sliding, it can be surely prevented from sliding and opening.

And if it slides with respect to a housing main body in the state which the surface opposite to a component mounting surface is exposed mainly, it will mount | wear easily.

Means 18
Further, cables and connectors led out to the outside are attached to the control board, and an opening is required on the housing side corresponding to the cables and connectors. When the case body and the lid are connected by a hinge, the opening of the cable outlet must be enlarged so that it does not interfere with the cable or connector because of the relationship of drawing an arc when opening and closing. The shape could not be in close contact with the board surface.

However, when the control board of the gaming machine is held by the lid body and is slid and attached to the housing body in the held state, the cable take-out position and connector on the component placement surface on the control board A wall material may be extended from the inner peripheral wall surface of the lid body facing the peripheral portion of the mounting position, and the tip of the wall material may be in contact with the control board so that no gap is generated.
Even in this case, since the component mounting surface is attached toward the inner surface of the lid, the wall material can be extended so that the opening for the cable and the connector is in close contact with the substrate surface. Injustice can be prevented by reducing the gap generated between the outside world as much as possible.

Mean 19

FIG. 2 is an enlarged view of a main part, and FIG. The section is broken to make the cross-sectional structure easier to see.
In the figure, the main body 10 has rail-shaped guide portions 11 and 11 on the sides facing each other out of the overall shape of a substantially rectangular shape. The hook-shaped portions 24, 24 formed on the sides can be slid and mounted along the guide portions 11, 11. In this example, the lid 20 side has a deep shape, and the control board 30 used in the gaming machine is held from the component placement surface 31 side to the inner face while holding the control board 30. I have to.

A plurality of operating element holding portions 12 are connected to a side of the housing body 10 opposite to the insertion ends of the guide portions 11 and 11 by a breakable plate-like wall material 13. The operation element holding portion 12 is formed so as to face the lid 20 that is slid and mounted, and is formed by opening a recess 12a on the opposite surface facing the lid 20. . Here, the operation element holding portion 12 is formed of a transparent resin.
Slits (through holes) 12a1 and 12a1 parallel to each other are formed in the back wall of the recess 12a, and a portion 12a2 sandwiched between the two slits 12a1 and 12a1 has a substantially trapezoidal shape as shown in FIG. Further, the inner peripheral surface of the recess 12a is tapered so that the opening diameter becomes narrower toward the back. Then, plate-like wall portions 12b and 12b are erected on the surface opposite to the concave portion 12a from the outside of the openings of the slits 12a1 and 12a1 toward the lid 20 side.

  The resin operation element 40 is formed of a transparent resin in a substantially dish-like size that can be inserted into the recess 12a, and the surrounding wall faces forward so as to follow the tapered shape of the inner peripheral wall of the recess 12a. The slope becomes gradually narrower. A metal engagement piece 50 bent in a U-shaped cross section is held inside the dish. The metal engagement piece 50 is formed by bending a belt-like plate material into a U-shaped cross section and folding both ends inward at an acute angle. In addition, a resin piece 41 for retaining is inserted and fixed in a state in which the U-shaped portion is inserted into the recessed portion of the resin operation element 40.

  Initially, the resin operation element 40 is inserted into the recess 12 a of the operation element holding part 12 while holding the metal engagement piece 50. At this time, the folding ends 51 and 51 are bent and pushed when passing through the slits 12a1 and 12a1, and once passing, the folding ends 51 and 51 are caught by the portion 12a2 between the slits 12a1 and 12a1. It will not come out. This state is indicated by a two-dot chain line in FIG. 4. In this state, the resin operating element 40 is not pushed into the innermost part of the recess 12a, and the remaining pushing operation allowance is secured.

  On the other hand, a fixed receiving structure 21 is formed on the lid 20 side so as to face the operation element holding portion 12. The slits 21a1 and 21a1 are also formed on the fixed receiving structure 21 side so as to face the slits 12a1 and 12a1, but the openings of the slits 21a1 and 21a1 are widened from the operation element holding part 12 side. The plate-like wall portions 12b and 12b that are erected can also be inserted into the slits 21a1 and 21a1. Therefore, when the wall portions 12b and 12b are inserted into the slits 21a1 and 21a1, the opening width is substantially equal to that of the slits 12a1 and 12a1.

On the fixed receiving structure 21 side, an engaged portion 21b having a trapezoidal cross section is formed between the slits 21a1 and 21a1. Tapered inclined surfaces 21b1 and 21b1 are formed in the engaged portion 21b so that the opening is enlarged on the side facing the operation element holding portion 12 and the opening is narrowed on the opposite side.

It is equivalent to 12a1 and 12a1. And if the resin operating element 40 is pushed in, the front-end | tip of the metal engaging piece 50 will be pushed in into said slit 21a1, 21a1. At this time, the folding ends 51 and 51 are bent to pass through the slits 21a1 and 21a1, and are opened again when they pass through the slits 21a1 and 21a1. In the opened state, the leading ends of the folding ends 51, 51 face the recess 21b2 formed on the back surface of the engaged portion 21b, and when the lid 20 is slid away from the housing body 10, the folding ends Since the tip ends of 51 and 51 enter the recess 21b2 and bite into the recess 21b2, they do not come out.

Further, since the wall portions 12b and 12b enter the slits 21a1 and 21a1 and sandwich the metal engagement piece 50, the wall surface surrounding the metal engagement piece 50 is doubled and illegal from the outside. There is also an effect of preventing the addition of.
Before the pressing operation, there is a gap between the outer peripheral wall surface of the resin operating element 40 and the inner peripheral wall surface of the recess 12a as shown by a two-dot chain line in FIG. 4, but after the pressing operation is shown in FIG. Thus, there is almost no gap between the outer peripheral wall surface of the resin operating element 40 and the inner peripheral wall surface of the recess 12a. By eliminating the gap, it is almost impossible to pull out the resin operating element 40 from the outside, and fraud can be prevented. Moreover, since there is a gap at the beginning, it can be pushed in lightly.

Here, it is also possible to employ a metal engagement piece 52 as shown in FIGS.
The metal engagement piece 150 shown in the figure is cut so as to be divided into three equal parts in the width direction from the front end of the belt-like plate material, and the two pieces on both sides are folded inward and the one piece in between is folded outward. Folded ends 151 and 151 are folded on both sides.
As shown in FIG. 8, the metal engagement piece 150 is held by the resin operation element 140, and the operation element holding part 112 is inserted into the recess 112a from the folded ends 151 and 151 side. Then, initially, the resin-made operation element 140 is temporarily supported by the operation element holding part 112 in a state in which it has passed through the slits 112a1 and 112a1. Further, when the fixed receiving structure 121 is made to face and the resin operating element 140 is further pressed, the folded ends 151 and 151 are pressed against the openings of the slits 121a1 and 121a1 formed on the fixed receiving portion 121 side and bent. It passes through the slits 121a1 and 121a1 while being narrow. And if it passes, since the folding | turning ends 151 and 151 will be restored | restored to the original width | variety, they will not come out unless force is applied so as to open the folding shape forcibly. Further, since it is folded back on both sides, any folded piece hits against the opening edge of the slit 121a1 even if it is moved to one side within the gap of the slit 121a1. This can be prevented from coming out even if the accuracy required for the manufacturing error in forming the folded end 151 is low, and the quality control is facilitated.

  By the way, as shown in FIGS. 1-3 of the operation element holding | maintenance part 12 and the fixed receiving structure 21 mentioned above, five pairs are provided. Further, five operating element holding portions 12 are erected on one side of the housing body 10, and when the lid body 20 is slid and attached to the housing body 10, a fixed receiving structure 21 formed on one side of the lid body 20. Is in contact with the waiting operator holding part 12. Here, the site | part which the folding | returning ends 51 and 51 of the said metal engagement piece 50 in the fixed receiving structure 21 engage exists in the inner side of the cover body 20, ie, the inside of the said housing. Accordingly, in order to release the engaging portion in order to perform fraud, the casing must be opened, so that fraud is virtually impossible.

  On the other hand, since it is necessary to open the casing when necessary including inspection, the operation element holding portion 12 can be separated from the casing main body 10. As shown in FIGS. 1 to 3, each of the operation element holding portions 12 is formed in a substantially box shape capable of accommodating the resin operation element 40, but each operation element holding portion 12 is formed by a plate-like wall material 13. It is connected. FIG. 9 shows a connection state of the plate-like wall members 13 that connect the respective operation element holding portions 12. Originally, it is sufficient that the plate-like wall material 13 is disposed only in the lower part of the figure so that the operating element holding part 12 is erected from the housing body 10. However, in this embodiment, the plate-like wall material 13 is also formed between the operation element holding portions 12 arranged side by side. The operation element holding part 12 itself should be arranged so that it can be visually confirmed whether it has been opened illegally. For this purpose, all the operation element holding parts 12 arranged side by side are arranged so as to be visible. If so, the plate-like wall material 13 formed between the arrangement directions of the operation element holding portions 12 should always be visible, and can be easily visually recognized if the plate-like wall material 13 is illegally broken. If this is only the back side of the operation element holding part 12, it becomes difficult to visually recognize the damaged part.

  On the other hand, the operation element holding portions 12 are formed symmetrically in the horizontal direction. At first glance, the number of plate-like wall members 13 that support each operation element holding portion 12 is the same, but differs in actual use. For example, as shown in FIG. 9, when the operating element holding part 12 is released for the first time, the three plate-like wall members 13 must be broken so that the broken part is indicated by a circle. However, when the second operation element holding portion 12 is released, there are two plate-like wall materials 13 to be damaged as indicated by Δ. Since this difference affects the ease of release, normally, if there is almost no release itself, the greater the number of plate-like wall materials 13 that should be damaged when the release is made for the first time, the more incorrect it is. It becomes difficult.

  In addition, it is clear that it must be released once when it is necessary to assemble it once before going through the inspection process. For this reason, the first operator holding portion 12 may be supported only by the lower plate-like wall material 13, and the plate-like wall material 13 between the side by side may not be formed. In this way, only one plate-like wall material 13 needs to be damaged during the inspection process, and the damaged portion is not visible from the front, so that it looks good when shipped as a product.

The ease with which the plate-like wall member 13 is damaged can be adjusted not only by the number of plate-like wall members 13 but also by the thickness.
By the way, about the part hidden behind the operation element holding | maintenance part 12 among the plate-shaped wall materials 13, it is hard to visually recognize destruction from the front side. For this reason, as shown in FIG. 10, you may make it extend the plate-shaped wall material 13a to the outward from the shade of the operation element holding | maintenance part 12 which is an obstruction. If it does in this way, even if it performs the fraud which scrapes or destroys the extended plate-shaped wall material 13a, it will come to be easily visible from the front side.

  In the above-described embodiment, the operation element holding unit 12 and the resin operation element 40 are both formed of a transparent resin. However, by coloring the resin operation element 40, fraud can be prevented. . For example, the coloring combination can be changed for each version or lot of the control box or each destination store. As a means of fraud, there is a technique in which an old model control box or an old version control box is fraudulently replaced. However, if the combination of coloring is changed for each version, lot, or destination store, the combination of coloring is different from the control boxes of other models, so that even if they are replaced, they can be recognized immediately.

As a coloring method, the resin operation element 40 may be colored, or the resin operation element 40 may be colored while coloring the resin piece 41 mounted on the inside. Also in the latter case, since the periphery of the resin piece 41 is a transparent member, coloring can be easily visually confirmed.
In the present embodiment, the control board 30 is held on the side of the lid 20 that is slid and removed. FIG. 11 is a sectional view showing the holding state. Usually, when the control board is held on the housing body, the lid cannot be brought into close contact with the control board, and a gap tends to be generated somewhere. For example, there is a possibility that a gap is generated in the cable drawing portion, and a foreign object is inserted through this gap to try fraud.

  However, in this embodiment, the control board 30 is accommodated with the lid 20 having a deep shape facing the inner surface from the component placement surface 31 side. Further, the shielding wall member 22 is erected from the inner peripheral surface of the lid 20 so as to surround the IC socket 32 and the IC 33 which are important components on the control board 30, and the tip of the shielding wall member 22 is almost the control board 30. It is in contact with the surface. For this reason, it is impossible to reach the IC 33 with foreign matter.

Further, since the cable 34 itself must be led out to the outside, the surface of the control board 30 must be exposed to the outside. However, a gap is not generated by forming the shielding wall member 23 long enough to contact the control board 30 around the cable 34 from the opening portion. As a result, it becomes impossible to insert a foreign object or the like.
FIG. 12 shows a modification of the present invention. In the previous embodiment, the operating element holding part 12 and the fixed receiving structure 21 face each other by the slide of the lid 20 and the housing body 10. However, in this modified example, the operating element holding part is sandwiched between the sliding surfaces. 12 and the fixed receiving structure 21 face each other. Therefore, by gradually sliding the lid 20 with respect to the housing body 10, the two gradually start to overlap and finally face each other. In this face-to-face state, the resin-made operating element 40 is pushed all the way into the operating element holding part 12, whereby the held metal engaging piece 50 crosses the slide surface and enters the mating fixed receiving structure 21. Engage.

Further, as a modification of the structure facing each other with the slide surface interposed therebetween, a configuration as shown in FIGS. 13 and 14 can be adopted.
In the figure, the total length of the resin operation element 240 held on the operation element holding part 112 side is set long, and the tip of the resin operation element 240 is positioned on the fixed receiving structure 221 side. A recess 225 into which can be inserted is formed.
As a result, when the resin operation element 240 is pushed, the resin operation element 240 is pushed into the back of the operation element holding portion 212. As a result, the resin operation element 240 is slid. The metal engaging piece 250 is also engaged while entering the recess 225 across the surface. Since the resin operation element 240 crosses the slide surface, the resin operation element 240 restricts such movement and cannot be slid even if the lid and the casing main body are slid. As a result, the sealing function can be further strengthened.

FIG. 15 shows the pachinko machine in a rear view, and a control box to which the main body sealing structure is applied is mounted so that it can be seen from the back side.
A rectangular box-shaped control box 70 is mounted on the back side of the pachinko gaming machine 60. Here, the control box 70 can be opened and closed by a hinge mechanism formed on one side of the long side, and the main body sealing structure is adopted on both short sides. That is, four pairs of the fixed receiving structure 21 of the lid and the operation element holding portion 12 of the casing are formed on the short sides of the lid and the casing, respectively, and can be sealed. Of course, it can be opened as required. As shown in the figure, since the pachinko machine 60 is disposed at a position that can be directly seen from the back side of the pachinko machine 60, it can be easily seen when the pachinko machine 60 is opened for maintenance. Therefore, if the fixed receiving structure 21 or the operation element holding portion 12 is damaged due to a change in the control box 70 or the like, it will be found immediately at the time of the next maintenance.

  FIG. 16 shows the back of the slot machine (pachi slot) 80. A rectangular box-shaped control box 90 is also mounted on the back side of the slot machine 80. Here, the control box 90 can be opened and closed by a hinge mechanism (not shown), and a main housing sealing structure is adopted on both short sides. That is, the lid fixed receiving structure 21 and the casing operator holding portion 12 are formed in pairs of four on the short sides of the lid and the casing, respectively, and can be sealed and opened as necessary. You can also.

As shown in the figure, a control box 90 is also mounted on the back side of the slot machine 80, and when the slot machine 80 is opened for maintenance, the housing sealing structure can be easily seen. Therefore, if the fixed receiving structure 21 or the operation element holding portion 12 is damaged to add a hand to the control box 90 or the like, it will be found immediately during the next maintenance.
Although not shown, the present invention can be similarly applied to a patty lot. The pacilot uses a pachinko game ball instead of a medal. For example, five pachinko balls can be equivalent to one medal and enjoy a game.

  Thus, while providing the operation element holding part 12 having the recess 12a on the side of the housing body 10, the resin operation element 40 holding the metal engagement piece 50 is temporarily supported in the recess 12a. A fixed receiving structure 21 is formed on the side of the lid 20 attached to the housing body 10 at a portion facing the operation element holding portion 12 when the lid 20 is slid and attached. Then, when the resin operating element 40 is pushed when the housing body 10 and the lid 20 are mounted, the folded end 51 of the metal engagement piece 50 enters the slit 21a1 of the fixed receiving structure 21 and engages. And sealing is completed.
