Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaming machine having a control box that can be sealed with a housing sealing structure.
[0002]
[Prior art]
A gaming machine such as a pachinko machine employs a housing sealing structure that prevents the control box from being easily opened and closed in order to prevent unauthorized modification of the control unit.
Conventionally, what is shown in FIG. 15 and FIG. 16 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]
Further, a plate-like spare screw holding piece 2a1 is extended to the protruding piece 2a outside the control box at a position shown below in the figure, and the spare screw 3 penetrates the spare screw holding piece 2a1. It is held in the state.
[0007]
[Problems to be solved by the invention]
The conventional opening portion sealing structure described above has the following problems.
Since only the resin wall material is disposed on the back side of the nut holding portion, 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 forward. 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.
[0008]
Since the spare screw 3 is held outside, there is a possibility that it will be lost. In addition, if the spare screw 3 is improperly made in advance, it may be modified so that it can be released at the time of sealing. There was also sex.
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.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, an invention according to claim 1 is a gaming machine having a control box that can be sealed with a casing sealing structure, wherein the casing sealing structure is sealed using a metal piece. In addition, the control box has a configuration in which an accommodating portion capable of holding a reserve of the metal piece is formed at a position where the metal piece is shielded.
[0010]
In the invention according to claim 1 configured as described above, it is assumed that the casing sealing structure is sealed using a metal piece, and the metal box is preliminarily held in the control box. If a part is formed and a spare metal piece is accommodated in the accommodation part, the spare metal piece shields the metal piece acting as a housing sealing structure. Therefore, even if a part of the control box is broken and fraud is attempted, the spare metal piece becomes a barrier, and the control box cannot be easily broken.
[0011]
As described above, there are various portions for shielding the metal piece of the casing sealing structure, and even if it is referred to as shielding, it is not necessary to completely cover it. Therefore, the shielding may be any part that makes it difficult to damage such a part of the enclosure sealing structure by breaking it in some way.
The present invention is not limited to the above configuration, and includes the following means.
Mean 1
A plurality of the casing sealing structures are formed side by side, and the housing part is formed at an end part in the direction of arrangement.
[0012]
When configured as described above, since the spare metal piece is located outside the arrangement direction, when assuming an attack that tries to damage the enclosure sealing structure from the side, the spare is placed on the outermost side in the arrangement direction. Guard and make it harder to do fraud.
Mean 2
Each of the metal pieces may be formed in a plate shape, and a plurality of metal pieces may be stacked and stored in the storage portion.
If the metal piece is plate-shaped, it can be accommodated in an overlapping manner, and if it is accommodated in an overlapping manner, it becomes difficult to be destroyed from the outside by the amount of the accumulated thickness.
[0013]
Mean 3
The plate-shaped metal piece may be accommodated in a planar shape.
By making it planar, the gap is reduced and it is difficult to damage from the outside.
Mean 4
As a method of forming a planar shape using a plate-shaped metal piece, it may be fitted into a frame member in which a hole substantially matching the outer shape of the metal piece is formed to form a single plate shape.
In this case, since the metal piece and the frame form a substantially complete single plate, the gap is the smallest. Also, such a frame itself is efficient if it is formed by processing the remainder when the metal piece is die-cut with a die punch.
[0014]
Mean 5
Further, when the plurality of metal pieces have irregularities, they may be alternately faced to form a planar shape.
For example, if the metal piece is L-shaped, one side may be turned upside down and brought close to each other, and if it is U-shaped, the other straight part is inserted into the U-shaped recess while being turned upside down. And close.
Mean 6
Further, as another configuration example of the housing part, when a housing sealing structure is formed on one side of the control box, a housing hole is formed on the side of the control box from the bottom surface to the back side of the housing sealing structure. And you may make it shield the back side of the enclosure sealing structure.
[0015]
If it does in this way, the attack which is going to be damaged from the back | inner side of the same enclosure sealing structure can be coped with.
In this example, the bottom surface of the control box is illustrated, but in the opposite case, that is, the housing hole from the ceiling surface to the side may be formed on the lid side as well.
Mean 7
The control box is composed of a housing body and a lid, but may be configured to slide both together.
Mean 8
When sliding and uniting, the mounting direction of the metal piece used in the casing sealing structure and the opening / closing direction of the lid body and the casing can be orthogonal or parallel to each other. However, if both directions are orthogonal, it is easy to effectively prevent the lid and the casing from being opened simply by preventing the metal piece from coming off.
[0016]
For example, an insertion hole is formed in the casing along the orthogonal direction, and a through hole facing the hole is formed in the lid, so that the metal is aligned when the lid and the casing are aligned. The piece is fixed by inserting the insertion hole from the through hole. At this time, a part of the metal piece is stopped in the insertion hole.
When this is done, the mounting direction of the metal piece and the sliding direction of the lid and the housing are orthogonal. And since it is the fracture endurance of the metal piece itself that prevents the sliding of the lid and the casing, it cannot be opened unless an extremely great force is applied.
[0017]
Mean 9
When a plurality of enclosure sealing structures are formed as described above, the control box itself may have to be opened and closed depending on the application. If a portion to be damaged when releasing the housing sealing structure is called a connecting portion, the number of the connecting portions in each housing sealing structure may be 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 sealed initially. Further, if the sealing is always opened twice when the inspection process or the like is performed, the number of connecting portions in the casing sealing structure 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.
[0018]
Mean 10
Such a connection part may be arranged on a plane when the control box is viewed from the front.
Although it is hard to notice fraudulently if it is in a place where it is difficult to see even if the connecting part is damaged, 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, preventing fraud. it can.
Mean 11
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 disposed on the control board.
[0019]
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.
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.
[0020]
Mean 12
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.
[0021]
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.
[0022]
Mean 13
The superiority of the configuration in which the housing part is formed at the position where the metal piece is shielded to hold the reserve of the metal piece is improved by the shape of the metal piece. As an example, the casing sealing structure has a metal piece that forms a U-shaped folded portion, and the U side of the metal piece faces the contact surface between the casing and the lid on the casing side. An insertion hole into which both ends folded back into the mold can be inserted, and a spring piece for locking the inner side of the metal piece that is folded back in the insertion hole to prevent the metal piece from being inserted; It is set as the structure provided with the penetration hole which can be penetrated through the both ends which turned up the U shape in the said metal piece facing the hole.
[0023]
In this case, when sealing, in the state where the insertion hole of the housing and the insertion hole of the lid are aligned so as to face the contact surface of the housing and the lid, the side of the insertion hole Insert metal pieces folded back into U shape. 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.
[0024]
Here, since the spring piece is engaged with the folded inner portion of the metal piece, an illegal attack from the outside can be prevented from the shape of the metal piece itself. However, it is weak against attack from the side surface direction, and the above-described accommodation site may be formed at a position where the metal piece is shielded in this direction.
Mean 14
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.
[0025]
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.
[0026]
Mean 15
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.
Slot machines are also 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.
[0027]
Mean 16
In addition, the gaming machine is a pachilot, 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 pachilot, and the same enclosure is opened when the pachilot is opened. It is set as the structure arrange | positioned in the position which can visually recognize a sealing structure easily.
Pachilot is a gaming machine that has the characteristics of both a pachinko machine and a slot machine that perform picture matching using a certain number of pachinko balls instead of medals. Such pachilots are also 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.
[0028]

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.
[0035]
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.
[0036]
Five insertion hole forming portions 12 are connected to the side opposite to the insertion end of the guide portions 11, 11 in the housing body 10.
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.
[0037]
Two preliminary accommodating portions 13 for accommodating spare metal pieces 40 are formed on the outside so as to sandwich the five insertion hole forming portions 12 in the main body 10, and each of the two metal pieces 40 is totaled. Four spares can be entered. 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.
[0038]
The preliminary accommodating portion 13 is not limited to only accommodating the spare metal piece 40 but also plays a role of preventing fraud with respect to the casing sealing structure. Before explaining the same role, the same enclosure sealing structure will be explained.
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.
[0039]
The leaf spring 50 is formed by bending a strip-shaped metal plate piece into an approximately L shape. More specifically, the tip 51a of the long piece 51 is folded at an acute angle in the opposite direction to the short piece 52, and is elastically supported by cutting from both sides of the long piece 51 from the short piece side. The claws 51c and 51c are formed, and at the center portion of the long piece 51, three portions are cut into a U-shape along the length direction, and the inside thereof is raised and cut and raised to form a claw 51d.
[0040]
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.
[0041]
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.
[0042]
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.
[0043]
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.
[0044]
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.
[0045]
The casing sealing structure having the above configuration seals the casing body 10 and the lid body 20 by engaging the metal piece 40 and the leaf spring 50. The engagement between the metal piece 40 and the leaf spring 50 is performed by the cut and raised claw 51d entering the cutout portion 41c.
Here, FIG. 1 illustrates directions A, B, C, D, E, and F, which indicate attack directions for performing fraud on the enclosure sealing structure. The direction A indicates that the insertion hole forming portion 12 is attacked from the outside in a direction parallel to the sliding direction. In this case, even if the resin insertion hole forming portion 12 can be cut, since the long piece 51 of the leaf spring 50 is made of metal, subsequent cutting is difficult and fraud can be prevented. Similarly, the B direction is a direction parallel to the sliding direction with respect to the insertion hole forming portion 12, but does not need to be considered because it is an attack direction from the inside. The C direction is an attack from the lower side of the insertion hole forming portion 12, and since the cut and raised claw 51d enters the cutout portion 41c, an attack from the outside is difficult. Further, it is impossible to pull the leaf spring 50 downward because the short piece 52 and the tip 52a sandwich the wall material 12c. Further, since the metal piece 40 is formed in a U shape in the D direction, the engagement site is completely covered and attacked is difficult.
[0046]
On the other hand, the E direction and the F direction are susceptible to attack because there is only a resin wall material. However, in the present embodiment, the two preliminary accommodating portions 13 are arranged on the outside so as to sandwich the five insertion hole forming portions 12. And since the spare metal piece 40 is accommodated in each preliminary | backup accommodating part 13 and 13, although it can cut about the outer side wall in the preliminary | backup accommodating part 13, it will contact | abut the metal piece 40, and subsequent cutting is carried out. Almost impossible. As a result, the insertion hole forming portion 12 cannot be reached, and fraud to the housing sealing structure can be substantially impossible.
[0047]
The position of the preliminary accommodating portion 13 that accommodates the spare metal piece 40 is not necessarily limited to the position sandwiched outside in the arrangement direction of the insertion hole forming portions 12.
4 and 5 show a modification of the arrangement of the preliminary accommodating portion. In this example, the preliminary accommodating portion 113 is disposed on the bottom portion of the insertion hole forming portion 12 while leaving the preliminary accommodating portion 13 on the side. More specifically, in the previous embodiment, the concave portion 12a1 into which the folded tip 51a of the long piece 51 enters is extended in the direction B shown in FIG. . In other words, the preliminary accommodating portion 113 forms a concave portion 12a1 extending from the bottom surface of the control box toward the back side of the housing sealing structure, and houses the metal piece 40 on the back side of the housing sealing structure. And shielding.
[0048]
If the spare metal piece 40 is accommodated in the spare accommodating portion 113 in this way, it will hit the metal piece 40 even if it is attempted to cut the insertion hole forming portion 12 using a file or the like from the C direction. Can no longer cut. Of course, this embodiment itself has a configuration corresponding to an attack from below, but the conventional type as shown in FIG. 10 is vulnerable to an attack from below as described above. Therefore, a recess for accommodating the spare screw 3 is formed laterally from the bottom surface of the control box, and the inner side of the enclosure sealing structure that is vulnerable to attack can be shielded to prevent unauthorized attacks.
[0049]
Similarly, the preliminary accommodating portion 113 can be appropriately formed at a position that serves as a shield against unauthorized attacks.
Depending on the shape of the spare metal piece 40 used for shielding, the shielding range may be narrow. For this reason, the modification which enabled it to form a shielding range as planar as possible is shown in FIG. 6 and FIG.
When the metal piece 40 is formed by punching with a press, a hole having the same shape as the punched metal piece 40 is formed on the material side. By utilizing this fact, the wider frame 42 is punched out on the material side, and it is integrated and accommodated in the preliminary accommodating portion 213 until it is used. In the preliminary accommodating portion 213, a slit 213a corresponding to the thickness of the metal piece 40 is formed so that the metal piece 40 and the frame 42 are not detached, and the metal piece 40 and the frame 42 are combined. Insert it with.
[0050]
In this way, since the substantially planar metal plate material is shielded, it is possible to reliably protect against unauthorized attacks. In addition, the used material can be used effectively.
Further, FIG. 8 and FIG. 9 show other modified examples constituting the planar shape. In this example, the shape of the cutout portion 41c of the metal piece 40 is changed, and as shown in FIG. 8, the unevenness of the metal pieces 40 turned upside down is made symmetrical. If formed symmetrically in this way, as shown in FIG. 9, they can be brought into close proximity and merged with almost no gap, and a single metal plate piece can be formed. Then, in the same manner as the previous example, as shown in FIG. 10, it is inserted into the slit 313a of the preliminary accommodating portion 313 and held.
[0051]
In this way, it is not necessary to dare to punch out the frame 42 and the metal piece separately, and it is possible to form a planar metal plate piece with almost no gap to protect against unauthorized attacks.
Next, the casing sealing structure will also be described.
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.
[0052]
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.
[0053]
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.
[0054]
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.
[0055]
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. 11, 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 breakage 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.
[0056]
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.
[0057]
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.
In the present embodiment, the control board 30 is held on the side of the lid 20 that is slid and removed. FIG. 12 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 the gap to try fraud.
[0058]
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.
[0059]
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.
In addition, FIG. 13 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.
[0060]
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.
[0061]
FIG. 14 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.
[0062]
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.
[0063]
In this way, when the control box is formed by combining the housing body 10 and the lid body 20 that are slid to open and close, the five insertion hole forming portions 12 are previously formed side by side on the housing body 10 side. Two preliminary accommodating portions 13 are formed so as to be sandwiched outside. When the spare metal piece 40 is accommodated in the preliminary accommodating portion 13 and the leaf spring 50 is inserted into the insertion hole forming portion 12, and the lid 20 and the housing body 10 are in a corresponding positional relationship, the metal The metal piece 40 is inserted into the piece insertion portion 21 and is locked by the leaf spring 50. In this state, the locking portion is sandwiched between the preliminary accommodating portions 13 and 13 on both sides, and the spare accommodating portions 13 and 13 contain the metal piece 40, so that the illegal cutting such as cutting from the outside is performed. Protected from violent attacks.
