Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaming machine having a control box that slides open and close.
[0002]
[Prior art]
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. 10 and FIG. 11 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.
[0003]
As shown in FIG. 11, 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 thread portion 4a formed on the inner peripheral surface is fitted into the nut holding portion 2a. 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.
[0004]
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.
[0005]
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.
[0006]
Moreover, what is shown in FIG. 12 is known as another housing sealing structure.
In the same figure, the protruding piece 5 a on the lid 5 side and the protruding piece 6 a on the housing body 6 side face each other and are sealed using the spring piece 7. The spring piece 7 is formed in a substantially plate shape so that it can be inserted from the slit 5a1 formed in the protruding piece 5a of the lid body 5. The upper edge is rounded to form the support portion 7a, and the lower middle portion has A cut and raised claw 7b raised on the side opposite to the insertion direction is formed. On the other hand, a slit 6a1 is formed in the projecting piece 6a of the housing body 6 corresponding to the slit 5a1, and when the spring piece 7 is inserted through the slit 5a1 of the lid body 5, the slit of the housing body 6 is left as it is. It is inserted into 6a1. The opening width is narrow at the back of the slit 5a1, and the support portion 7a is caught and does not come out as it is. On the other hand, a small chamber 6a2 perpendicular to the through direction of the slit 6a1 is formed on the slit 6a1 side so as not to prevent the insertion of the cut and raised claw 7b but to prevent the pulling out. Therefore, when the spring piece 7 is inserted, the raising claw 7b enters the small chamber 6a2 and thereafter is prevented from being pulled out in the direction opposite to the insertion direction.
[0007]
After the spring piece 7 is inserted, the opening of the slit 5a1 of the lid 5 is filled with an ultraviolet curable resin. Thereby, it becomes impossible to extract the spring piece 7 from above.
[0008]
[Problems to be solved by the invention]
The conventional opening portion sealing structure described above has the following problems.
In the former example, when tightening is insufficient during work, there is room for turning in the opposite direction. Further, only the resin wall material is arranged on the back side of the nut holding portion, and there is a possibility that the screw 3 can be removed if this portion is broken and the screw 3 is rotated backward while urging the screw 3 toward the front side. . In this case, since only the back side is destroyed, it is not easily known that the front side is destroyed, and fraud may not be found for a long time.
[0009]
In the latter example, it is impossible to pull out the spring piece 7 from above by filling it with an ultraviolet curable resin, but a thin plate-like thing with a slit 6a1 opened on the back side of the housing body 6 is used. If it is inserted and caused to lay down the nail 7b, it will not interfere with the small chamber 6a2, and the sealing can be released.
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a gaming machine that employs a casing sealing structure that can make unauthorized modification difficult.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 is a gaming machine having a control box that can be opened and closed, and the control box includes a housing and a lid and seals both in a closed state. The housing sealing structure has a metal piece that forms a U-shaped folded portion, and faces the contact surface between the housing and the lid on the side of the housing. An insertion hole into which both ends of the metal piece folded back into a U shape can be inserted; and a spring piece for locking the inner side of the metal piece that is folded back within the insertion hole to prevent the metal piece from being removed; Is provided with an insertion hole through which both ends of the metal piece folded back into a U shape can be inserted so as to face the insertion hole.
[0011]
In the invention concerning Claim 1 comprised as mentioned above, it has the control box of the said game machine, and can seal the said control box in a closed state by the housing sealing structure. When sealing, a metal piece folded back into a U shape from the side of the insertion hole in a state where the insertion hole of the casing and the insertion hole of the lid are aligned to face the contact surface between the casing and the lid Will be inserted. A spring piece is provided inside the insertion hole of the housing, and when the metal piece is inserted, the metal piece is engaged with the folded back inner portion to prevent the metal piece itself from coming off. In this state, the metal piece folded back into the U shape is inserted into the housing side so as to straddle part of the lid body and is prevented from coming off, and the housing body and the lid body are relatively immovable. Therefore, both are sealed.
[0012]
In this way, the metal piece folded back into the U shape can be prevented from coming off at the inner part thereof, and it is necessary to destroy the inner part of the metal piece when trying to release the retaining. However, since it has a U-shaped shape, it is extremely difficult to destroy the inside, and as a result, the effect of preventing fraud is high. That is, the metal piece and the spring piece cooperate to eliminate fraud to the spring piece, thereby preventing the control box from being opened improperly.
[0013]
The present invention is not limited to the above configuration, and includes the following means.
Mean 1
You may form with a leaf | plate spring as a structure of the said spring piece.
If it is a leaf | plate spring, it can latch easily by forming a notch site | part inside the metal piece made into U shape inside the metal piece.
Mean 2
As a configuration of the leaf spring, a cut-and-raised claw is formed by obliquely raising an inner strip piece while forming a groove in a U-shape, and an inner portion of the metal piece is formed at the tip of the cut-and-raised claw. A saw blade-shaped cutout portion may be formed so that the stopper can be prevented from coming off.
[0014]
By forming a saw blade-like notch in the metal piece, it can be inserted by simply bending the leaf spring in the insertion direction and bending it, but in the opposite direction the two bite each other and can be prevented from coming off. .
Mean 3
Here, the width of the cut and raised claw and the width of the metal piece are substantially the same. If the cut-and-raised claw has entered the saw-toothed cutout, observe the tip of the cut-and-raised claw if the width of the cut-and-raised claw is narrower when viewed from below the metal piece. I can't. Therefore, even if it inserts a foreign material from the lower part and cuts and raises it and lays a nail | claw, it will be prevented by the said metal piece. In that sense, if the cut-and-raised nail is slightly wider, it will not be possible to lay down the entire raised-and-clawed nail. It can be said that it includes even a width that cannot be laid down.
[0015]
Mean 4
The cut and raised claw is formed so as to face the inside of the control box.
If the cut-and-raised claw faces the outside of the control box, fraud such as making a hole in the outer wall and causing the claw to lie down is likely to be possible. However, if the cut-and-raised claw faces the inside of the control box, it is impossible to make a hole from the inside of the control box, so that fraud can be prevented.
Mean 5
A folded end that is bent toward the side where the raised and raised claw is raised may be formed on the front end side of the leaf spring forming the raised and raised claw.
[0016]
If you cut and raise the nail as described above, the metal piece will come off, but by folding the tip of the leaf spring in the same direction, you tried to insert the foreign object from below to the nail Sometimes it is not possible to advance beyond the folded end, and it is not possible to reach the cut-and-raised nail, thus preventing fraud.
Mean 6
Of course, the folded end is not simply formed by cutting and raising the nail, but by locking the folded end against the back side of the insertion hole of the leaf spring, the leaf spring is removed. You may make it impossible.
[0017]
In this way, it is possible to prevent both illegal access to the raised nail and the leaf spring from being pulled out.
Mean 7
The upper end side of the leaf spring may be formed in a substantially U-shaped cross section and locked to the edge of the insertion hole of the housing.
There are various types of irregularities with respect to the leaf spring, but it is also possible to pull out the leaf spring from below. As a countermeasure in such a case, if the upper end of the leaf spring is locked in a U shape, it can be prevented from being pulled out even if a hole is simply made on the lower side.
[0018]
Mean 8
The leaf spring may be provided with an elastic support claw for elastically supporting the base portion of the leaf spring toward the notch portion of the metal piece.
Since the base itself is elastically supported, it is difficult to cut and raise the claw when inserting the metal piece, and the reliability of retaining is improved.
Mean 9
The leaf spring may form the cut and raised claw on the inner side while forming the elastic support claw on both sides in the width direction.
[0019]
In this way, the leaf spring can be stably elastically supported, and as a result, the state in which the cut and raised claw is locked to the notch portion is also stabilized.
Mean 10
The elastic support claw may be formed with a planar portion facing the planar wall surface in the insertion hole on the distal end side.
Since the tip of the elastic support claw is a flat surface and faces the wall surface of the insertion hole, a stable posture can be maintained with the flat surfaces facing each other. As a result, the cut and raised claw is locked to the cutout portion. The state is also stable.
[0020]
Mean 11
The metal piece may be formed such that one of the folded metal pieces is long and the other is short.
Mean 12
The said metal piece may form the said notch part inside both while making the both ends folded back in U shape into substantially equal length.
Mean 13
The insertion hole of the lid may be filled with resin and cured in a state where the metal piece is inserted. In this way, it becomes difficult to pull out the metal piece regardless of whether or not the leaf spring is fraudulent, and fraud can be prevented.
[0021]
Mean 14
The insertion direction of the metal piece and the opening / closing direction of the lid and the housing can be orthogonal or parallel to each other. However, by making both directions orthogonal, it is possible to more effectively prevent the lid and the casing from being opened simply by preventing the metal piece from coming off. This is because when the metal pieces are folded in parallel, the metal piece folded back into the U shape is prevented from being opened by pressing the lid at the folded portion. It is determined only by the locking force of the leaf spring. Therefore, the fraud prevention effect cannot be increased unless the durability of each part such as a raised nail is increased. However, in the case of being orthogonal, the leaf spring is not related to the force for holding the metal piece, and it can be prevented from opening with the durability of the metal piece itself, so it cannot be opened unless a very large force is applied. .
[0022]
Mean 15
A plurality of pairs of the insertion hole and the insertion hole may be prepared, and one of them may form a connection part that can be easily broken between the other part and the other part.
If it does in this way, when it will be necessary to cancel | release after sealing, the same connection site | part may be damaged, sealing will be cancelled | released, and it can seal again using another pair.
Mean 16
This connection part may be arranged on a plane when the control box is viewed from the front.
[0023]
Although it is difficult to detect fraudulently if it is in a place where it is difficult to see even if the connecting part is bankrupt, if the connecting part is arranged on a flat surface when the control box is viewed from the front, the damaged part can be easily seen and fraud is prevented. it can.
Mean 17
The frequency of opening and closing may vary depending on the application. As an example suitable for such a case, the plurality of operation element holding portions may be configured such that the number of the connecting portions 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 parts which connect the operation element holding | maintenance part sealed initially. In addition, if the sealing is always opened twice when the inspection process or the like is performed, the number of connection parts for connecting the operation element holding portions used for the third sealing may be increased. The number of connected parts in this case is the number that requires breaking when unsealing, and it may be counted so as not to include the number of wall materials that have already been broken when sequentially breaking. Good.
[0024]
Means 18
When preparing a plurality of pairs, it is convenient to hold a spare metal piece that is not normally locked, and at this time, it may be arranged on the side of the insertion hole on the side of the housing.
By holding a spare metal piece on the side of the insertion hole, the spring piece that prevents the metal piece from being removed is guarded from both directions by the metal piece folded back into a U shape, and the side is guarded by the spare. Is done. This makes it difficult to perform fraud.
[0025]
Mean 19
When the housing and the lid are slid and attached, the lid holds the control board of the gaming machine, and is slid and attached to the housing body in the held state, and the inside of the lid A wall material may be extended from the wall surface so as to surround the IC arranged in the same control board shape.
Conventionally, when placing the control board on the housing body, the component placement surface is directed to the opening side, and the lid body connected to the housing body by a hinge or the like is rotated to close the opening. Yes. That is, the IC or the like faces the opening side, and even if the opening is closed by the lid, there is nothing that covers the IC in the lid. For this reason, if there is a gap or the like, there is a possibility that a clever fraud is performed from the outside.
[0026]
On the other hand, in the invention configured as described above, the control board of the gaming machine is held by the lid. At this time, the component mounting surface of the control board is directed toward the inner surface of the cover body, and a wall material is extended from the inner peripheral wall surface of the cover body so as to surround the mounted IC. ing. As a result, it is possible to cover the side of the IC completely, and when it is covered in this way, it is possible to prevent fraud such as inserting foreign matter into the lower surface of the IC from the gap of the housing. 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.
[0027]
Mean 20
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.
[0028]
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.
[0029]
Mean 21
The metal piece may be colored in a predetermined color.
The sealing state can be shown by using color coding to be colored. Moreover, when accommodating a control board etc., you may make it show the version of the same control board. Furthermore, not only the version but also the shipping time may be expressed. When the version and the shipping date are indicated by coloring, in the case of a gaming machine, it can be understood that the control box has been exchanged due to the difference in coloring even if an attempt is made to cheat using the control box of the old model.
[0030]
Mean 22
Further, the present invention can be applied to various gaming machines, and is applied to a pachinko machine as an example of the gaming machine, and the casing sealing structure is arranged at a position that can be viewed from the back side of the pachinko machine.
Pachinko machines are opened frequently during business hours and the back side is visible. For this reason, fraud can be prevented by having the same enclosure sealing structure in the position which can be visually recognized from the back side.
In a gaming machine such as a pachinko machine, an IC in which a game program corresponding to the game content is recorded is accommodated in the control box, and there is a possibility that fraud in which the content of the IC is rewritten is performed. For this reason, fraud can be prevented beforehand by applying the housing sealing structure of the present invention to the control box.
[0031]
Mean 23
In addition, the gaming machine is a slot machine, and when this enclosure sealing structure is applied to a control box of a gaming machine, the control box is disposed inside or on the back side of the slot machine, and the slot machine is opened. It is set as the structure arrange | positioned in the position which can visually recognize the enclosure sealing structure easily.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a control box of a gaming machine to which a housing sealing structure according to an embodiment of the present invention is applied, and FIG. 2 is a perspective view broken away while enlarging a main part.
[0043]
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.
[0044]
Five insertion hole forming portions 12 are formed on the side opposite to the insertion end of the guide portions 11, 11 in the housing body 10, and a spare accommodating portion for accommodating a spare metal piece 40 on the outside thereof. Two 13 are formed. On the other hand, a metal piece insertion portion 21 having a slit into which the metal piece 40 can be inserted is formed at a position facing and covering each insertion hole forming portion 12 on the side of the lid 20 that is slid and mounted. The metal piece insertion portion 21 is connected to surrounding members via resin walls 22a and 22b that are relatively easily damaged. Note that a leaf spring 50 is accommodated in the insertion hole forming portion 12.
[0045]
FIG. 3 is a cross-sectional view of the housing sealing structure. The metal piece 40 is folded into a U shape and has two legs 41a and 41b. In this example, one leg 41a is long and the other leg 41b is short. Three cutout portions 41c are formed on the inner side of the long foot portion 41a, and each cutout portion 41c is formed as a concave portion of a saw blade-like protrusion 41d. The saw-toothed projection 41d faces a slope that makes it easy to get over the obstacle when the foot 41a is inserted, and has a direction that makes it easier to bite into the obstacle when the foot 41a is to be pulled out.
[0046]
The leaf spring 50 is formed by bending a strip-shaped metal plate piece into an approximately L shape. More specifically, as shown in FIG. 13, the tip 51 a of the long piece 51 is folded at an acute angle in the opposite direction to the short piece 52, and the short pieces are formed on both sides of the long piece 51. The elastic support claws 51c and 51c are formed by cutting and raising from the side of the side, and at the center portion of the long piece 51, the three portions along the length direction are cut into U-shapes and the inside thereof is raised and cut and raised claw 51d. Is formed.
[0047]
The elastic support claw 51 c is raised obliquely with respect to the long piece 51, but its tip is bent again to be parallel to the long piece 51. The cut-and-raised claw 51d is raised on the side toward the distal end side of the long piece 51. As shown in FIG. 3, when inserting the foot portion 41a of the metal piece 40, the saw blade-like projection 41d Although the insertion is not hindered, when the foot 41a is to be pulled out, the tip is inserted into the cutout portion 41c to prevent the removal.
[0048]
The width of the cut-and-raised claw 51d is set to be substantially equal to or less than the foot portion 41a of the metal piece 40. If it does in this way, when it sees from the downward | lower direction, the cut-and-raised claw 51d will be covered with the metal piece 40, and it will become difficult to insert a foreign material from the outside and to cut and raise the claw 51d.
About the direction which raises and raises the nail | claw 51d, it has turned to the inside of a control box. In this way, in order to lay the cut and raised claw 51d, it is necessary to make a hole from the inside of the control box, which can be realized only after the control box is opened, so that illegal actions can be prevented. Further, the tip 51a may be bent over the entire width as shown in FIG. In such a case, even if an attempt is made to insert a foreign object from below in order to lay the cut and raised claw 51d, the forward end is covered with the tip 51a and cannot be moved forward. Consequently, fraud can be prevented.
[0049]
Note that the tip 52 a of the short piece 52 is folded back in the same direction as the tip 51 a of the long piece 51. By folding back the tip 52a of the short piece 52 as described above, it is possible to face an illegal act of catching the opposite surface of the wall member 12c and pulling the leaf spring 50 downward in FIG.
The insertion hole forming portion 12 has two insertion holes 12a and 12b corresponding to the foot portions 41a and 41b of the metal piece 40. The long piece 51 of the leaf spring 50 is inserted into the insertion hole 12a corresponding to the longer foot portion 41a, and further, the distal end 51a of the long piece 51 enters and can be locked in the deeper portion. A concave portion 12a1 is formed.
[0050]
When the leaf spring 50 is inserted into the insertion hole 12a, the tip 51a enters the recess 12a1 and is prevented from coming off, and the elastic support claw 51c abuts against the wall surface of the insertion hole 12a and the long piece 51 slightly floats. It is supported in the state. Here, the short piece 52 does not enter the insertion hole 12a, but abuts against the wall material 12c formed between the insertion hole 12a and the insertion hole 12b, and the folded tip 52a of the short piece 52 is on the side of the insertion hole 12b. Get in. Therefore, the long piece 51 is urged to the side away from the wall material 12c by the elastic support claw 51c while the movement of the long piece 51 is restricted by the wall material 12c on the base side connected to the short piece 52, and the tip 51a is It will be securely held in the recess 12a1 so as not to come out.
[0051]
The metal piece insertion portion 21 of the lid 20 corresponding to the insertion hole forming portion 12 of the housing body 10 has a flat cylindrical main body portion 21a having a slit-like opening 21a1 so that a plate-like metal piece 40 can be inserted. The main body portion 21a is connected at one end in the longitudinal direction via the lid 20 and the resin wall 22a. The resin wall 22a is formed to be slightly thinner than the wall portions of other portions, and can be relatively easily broken at this portion. In addition, the resin wall 22b that connects the main body portions 21a in the side-by-side direction is formed to be wide as a whole, but a notch 22b1 is formed in the center from one end, and substantially only with a short width. It is connected. Therefore, it can be destroyed relatively easily at this site. In addition, in the slit-shaped opening 21a1, a bridging portion 21b for forming an opening into which the leg portions 41a and 41b of the bifurcated metal piece 40 can be respectively inserted is formed.
[0052]
Two spare accommodating portions 13 for accommodating spare metal pieces 40 are formed outside the five insertion hole forming portions 12, and each of the two metal pieces 40 has four spare portions in total. Can be put. The preliminary accommodating portion 13 has an opening upward, and the metal piece 40 can be inserted from above. Further, on the side of the lid 20, a preliminary accommodating portion lid portion 23 is formed at a position where the upper portion of the preliminary accommodating portion 13 is covered when being slid and attached to the housing body 10.
[0053]
In the above configuration, the leaf spring 50 is inserted into the insertion hole forming portion 12 in advance. When the long piece 51 of the leaf spring 50 is inserted all the way into the insertion hole 12a, the folded tip 51a enters the recess 12a1 and prevents the leaf spring 50 from coming out. Further, the short piece 52 is caught so that the folded tip 52a enters the insertion hole 12b on the opposite side while contacting the wall material 12c. At this time, the elastic support claw 51c formed in the middle supports the leaf spring 50 by floating a small distance from the wall material 12c. In addition, the leaf | plate spring 50 is mounted | worn in each of the five insertion hole formation parts 12, and the two metal pieces 40 are each inserted in the preliminary | backup accommodating part 13. As shown in FIG. Thus, the preparation on the side of the main body 10 is completed.
[0054]
On the lid 20 side, the control board 30 used in the gaming machine is made to face the inner surface from the component placement surface 31 side, and the control board 30 is held inside the lid body 20. Then, the bowl-shaped parts 24 and 24 are slid and mounted so as to be along the guide parts 11 and 11 of the casing body 10. When the lid 20 and the housing body 10 have a corresponding positional relationship, the metal piece insertion portion 21 and the insertion hole forming portion 12 overlap each other. Therefore, when the metal piece 40 is inserted into the slit-shaped opening 21a1 in the metal piece insertion portion 21, the insertion holes 12a and 12b of the insertion hole forming portion 12 are set such that both the foot portions 41a and 41b sandwich the bridging portion 21b. Go inside. When the foot portion 41a enters the insertion hole 12a, the cut-and-raised claw 51d interferes, but the inclination of the cut-and-raised claw 51d and the saw-toothed projection 41d formed on the foot portion 41a. The sloping surfaces are in a direction in which they can ride over each other, and the foot 41a can be inserted to a predetermined position in the insertion hole 12a. Of course, after insertion, they face each other so that they can bite in, so that they can be prevented from coming off. And since the leaf | plate spring 50 itself enters and hold | maintains in the recessed part 12a1 of the back of the insertion hole 12a in the front-end | tip 51a, the metal piece 40 cannot escape from the insertion hole formation part 12. FIG.
[0055]
As the foot portion 41a is inserted into the insertion hole 12a, the foot portion 41b is also inserted into the insertion hole 12b. In this state, the U-shaped metal piece 40 connects the tips of both foot portions 41a and 41b to the insertion hole forming portion. 12 is fixed. And since the part by which the metal piece 40 is folded back is stopped while sandwiching the bridging portion 21b in the opening 21a1 of the metal piece insertion portion 21 of the lid body 20, the lid body 20 cannot be slid, and as a result, the lid body 20 and the housing body 10 are sealed.
[0056]
Thereafter, when it becomes necessary to release the seal and open the control box, the resin wall 22a and the resin wall 22b are destroyed. Since the metal piece insertion portion 21 into which the U-shaped metal piece 40 is inserted is pressed onto the insertion hole forming portion 12 by the bridging portion 21b, when the lid 20 is slid from the housing body 10, it is sealed once. The lid body 20 can be separated from the housing body 10 while only the stopped metal piece insertion portion 21 remains on the housing body 10.
[0057]
By the way, the insertion hole forming portions 12 are formed symmetrically in the horizontal direction. At first glance, the number of resin walls 22a and 22b that support each insertion hole forming portion 12 is the same, but is different in actual use. For example, as shown in FIG. 4, when the resin walls 22a and 22b with respect to the insertion hole forming portion 12 at the bottom are destroyed, if it is the first time, there are three broken sites as indicated by ◯. However, when the second insertion hole forming portion 12 from the bottom is released, there are two parts to be damaged as indicated by Δ. Since this difference affects the ease of release, normally, if there is almost no release itself, the more the number of resin walls 22a and 22b that should be damaged at the time of the first release, the more fraudulent. It becomes difficult.
[0058]
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 insertion hole forming portion 12 may be supported only by the resin wall 22a, and the resin wall 22b between the side by side may not be formed. In this way, since only one resin wall 22a needs to be damaged during the inspection process, the time and effort for release is reduced.
[0059]
The ease with which the resin walls 22a and 22b are damaged may be adjusted not only by the number but also by the thickness.
Of course, the shape of the metal piece 40, the leaf spring 50, and the insertion hole forming portion 12 described above can be variously modified.
FIG. 5 shows an example in which the leaf spring 50 is fixed so as to surround the wall member 12c.
In the example described above, the tip of the long piece 51 is folded back and hooked, but in this example, the short piece 52 side is made longer than the wall material 12c, and this is inserted into the wall member 12c on the insertion hole 12b side. Is folded back (folded portion 52b), and the tip 52c is folded back. If it does in this way, since the wall material 12c will be pinched | interposed by the folding | returning part 52b and the elastic support nail | claw 51c of the long piece 51, the attitude | position of the leaf | plate spring 50 will be hold | maintained stably. In addition, the leaf spring 50 can be prevented from coming off by engaging the tip 52c of the short piece 52 with the wall member 12c.
[0060]
FIG. 6 shows an example in which the leaf spring 50 and the metal piece 40 are symmetrical to improve workability during mounting.
The plate spring 50 is formed with two long pieces 51, 51 via short pieces 52. And the recessed part 12a1, 12b1 is formed in each front-end | tip of insertion hole 12a, 12b, and it has the structure which latches at the front-end | tip 51a, 51a of each long piece 51,51. About the metal piece 40, both leg parts 41a and 41b are formed in equal length, and the notch part 41c and the sawtooth-shaped protrusion 41d are formed in both. Thus, since the leaf | plate spring 50 and the metal piece 40 are formed in the symmetrical shape, it does not accidentally attach directionality and can improve workability | operativity.
[0061]
In the present embodiment, the control board 30 is held on the side of the lid 20 that is slid and removed. FIG. 7 shows the holding state in a sectional view. 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 the gap to try fraud.
[0062]
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 25 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 25 is substantially 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.
[0063]
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, the gap is not generated by forming the shielding wall member 26 having a length that can 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. 8 shows the pachinko machine in a rear view, and a control box to which the main body sealing structure is applied is mounted so as to be visible from the rear side.
[0064]
A rectangular box-shaped control box 70 is mounted on the back side of the pachinko machine 60. Here, the control box 70 can be opened and closed by a hinge mechanism formed on one side of a long piece, and a main body sealing structure is adopted on both short sides. That is, the metal piece insertion portion 21 of the lid and the insertion hole forming portion 12 of the housing are formed in pairs of four on the short sides of the lid and the housing, 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 metal piece insertion portion 21 or the insertion hole forming portion 12 is damaged to add a hand to the control box 70 or the like, it will be found immediately during the next maintenance.
[0065]
FIG. 9 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 metal piece insertion portion 21 of the lid body and the insertion hole forming portion 12 of the housing body are formed in pairs of four on the short sides of the lid body and the housing body, respectively, can be sealed, and opened as necessary. You can also.
[0066]
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 visually confirmed. Therefore, if the metal piece insertion portion 21 or the insertion hole forming 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.
[0067]
In this way, when the casing body 10 that is slid and opened and closed and the lid body 20 are combined to form the control box, the leaf spring 50 is inserted into the insertion hole forming portion 12 on the side of the casing body 10 in advance. The control board 30 of the gaming machine is held inside the lid 20 and is slid and mounted. When the lid 20 and the housing main body 10 have a corresponding positional relationship, the metal piece insertion portion 21 and the insertion hole forming portion 12 overlap each other, so that the metal piece 40 is inserted into the opening 21a1 of the metal piece insertion portion 21. Then, the foot portion 41a is locked to the leaf spring 50 in the insertion hole 12a, and the metal piece 40 cannot come out of the insertion hole forming portion 12. Since the folded portion of the metal piece 40 is stopped while the bridging portion 21b is sandwiched in the opening 21a1 of the metal piece insertion portion 21 of the lid body 20, the lid body 20 cannot be slid. The casing body 10 is sealed.
