Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a gaming machine having a control box for accommodating a control board. 2. Description of the Related Art In a gaming machine such as a pachinko machine, in order to prevent unauthorized modification of a control unit and the like,
A housing sealing structure is adopted to prevent the openable control box from being easily opened and closed. Conventionally, as this kind of housing sealing structure, the one shown in FIG. 16 is known.
In the figure, a protruding piece 1a on the side of the lid 1 and a protruding piece 2a on the side of the housing body 2 face each other, and are sealed using a spring piece 3. The spring piece 3 is formed in a substantially plate shape so that it can be inserted from the slit 1a1 formed in the protruding piece 1a of the lid 1, and has a support portion 3a formed by rounding the upper end edge and a lower intermediate portion. A cut-and-raised claw 3b raised on the side opposite to the insertion direction is formed. On the other hand, the protruding piece 2a of the housing body 2 is provided with a slit 1a1 corresponding to the slit 2a1. When the spring piece 3 is inserted through the slit 1a1 of the lid 1, the slit of the housing main body 2 is left as it is. 2a1
It is inserted into. The opening width is narrow at the back of the slit 1a1, so that the support portion 3a is not caught and does not fall out as it is. On the other hand, slit 2
On the side of a1, a small chamber 2a2 orthogonal to the penetration direction of the slit 2a1 is formed so as not to prevent insertion of the cut-and-raised claw 3b, but to prevent pull-out. Therefore, if the spring piece 3 is inserted, the raising claw 3b
Is prevented from entering the small chamber 3a2 and subsequently being pulled out in the direction opposite to the insertion direction. After the insertion of the spring piece 3, the opening of the slit 1a1 of the lid 1 is filled with an ultraviolet curable resin. This makes it impossible to pull out the spring piece 3 from above. [0004] In the above-described conventional opening portion sealing structure, there is a problem that a spring piece is indispensable in addition to the ultraviolet curable resin. The present invention has been made in view of the above problems, and has as its object to provide a gaming machine employing a housing sealing structure capable of reducing the number of members required for sealing. [0005] In order to achieve the above object, an invention according to claim 1 is a gaming machine provided with a control box for accommodating a control board, and a housing constituting the control box. The main body and the lid each have a plate-like portion having a through hole formed at a substantially central portion thereof, and in a state where both plate-like portions are brought into contact with each other, the hardener reservoir is formed on the non-contact surface side of each plate-like portion Is provided with a pair of housing sealing members. [0006] In the invention according to claim 1 configured as described above, the casing main body and the lid constituting the control box are provided with a pair of casing sealing members. The pair of housing sealing members has a plate-like portion having a through hole formed at a substantially central portion, and when both plate-like portions are in contact with each other, a curing agent is provided on a non-contact surface side of each plate-like portion. A basin is formed.
When filling the uncured resin as an example of the curing agent in the curing agent reservoir on the non-contact surface side of one plate-like portion, an excess resin is formed in a substantially central portion of the through-hole, and further the other. It enters the non-contact surface side of the other plate portion through the through hole of the plate portion. The resin hardens in the hardener pools on both sides of the plate-shaped part, and the cross-section is shaped like a letter "D", and the resin that is larger than the through-hole is solidified with the resin that hardens in the through-hole. . Therefore, the two plate-shaped portions cannot be separated, and the housing body and the lid can be sealed. [0007] The present invention is not limited to the above configuration, but includes the following means. Means 1 The shape of the plate portion and the curing agent reservoir can be variously modified. First, as for one housing sealing member, a peripheral portion is erected on the non-contact surface side of the plate-shaped portion to form a substantially shallow dish shape, and the peripheral portion is similarly formed on the contact surface side. Install it in a cylindrical shape in the opposite direction. In addition, the other housing sealing member is configured by holding a pair of plate-like portions that enter the cylindrical portion with a connecting wall therebetween. In this case, when the pair of plate-like portions is inserted into the cylindrical portion of the other housing sealing member, the periphery is surrounded by the cylindrical portion while being vertically sandwiched between the plate-like portions. A closed space for the hardener pool is formed. And
As the resin is filled in the shallow dish-shaped portion of the housing sealing member on the side of the cylindrical portion, the resin enters the closed space from the central through hole. When the resin cures, the resin is cured in a closed space on one side with the through hole in between, and the resin is cured on the shallow dish-shaped part on the other,
The pair of housing sealing members cannot be separated from this state. Means 2 In the structure of Means 1, a slit is formed on the peripheral surface of the cylindrical portion of one casing sealing member, and the slit is formed on the side of the other casing sealing member from the connection wall. And a connection portion protruding to the outside through the connection portion. In this case, the cured shape of the resin is almost the same, but the shape when the resin is fixed to the control box of the other housing sealing member is changed. Therefore, it is useful if the connection position on the side surface of the tubular portion is more appropriate in the control box as described above. Means 3 In the above configuration, in order to fill the closed space with the resin, a second through hole as an air hole may be formed in the peripheral portion of each of the plate-like portions. When the resin is filled from the through hole at the center of the plate-like portion, it is necessary to push out air by the filled volume. In the case described above, if the resin is filled from the central through-hole, air flows out from the second through-hole on the peripheral edge, whereby the resin is more easily filled and diffused. Means 4 In the above example, it is assumed that the pair of housing sealing members move toward and away from each other along the axial direction of the through hole. However, of course, the movement is not limited to such a movement. For example, the above-mentioned shallow dish-like portion is formed above the plate-like portion of one housing sealing member, and an empty room that opens in the side direction is formed below that portion. Needless to say, the ceiling wall here is a plate-like portion having a through-hole formed at the center. The other housing sealing member has a configuration in which the opening can be closed from the side with respect to the empty room and the other plate-shaped portion can be inserted adjacent to the plate-shaped portion in the empty room. . [0012] In this case, the other housing sealing member approaches the one housing sealing member from the side, and
The opening of the empty room is closed while the plate-shaped portion is inserted into the empty room. Then, the resin is similarly filled from the shallow dish portion.
Then, the resin passes through the through holes of the plate-shaped portions overlapping each other, fills the lower empty room, and cures. When cured, the resin becomes similarly D-shaped in cross section, and when trying to move the other housing sealing member in the direction opposite to the insertion direction,
The resin that has passed through the through-hole and is hardened cannot be pulled out. Means 5 As a simpler structure, both housing sealing members are formed in a shallow dish shape, and the bottom surfaces are brought into contact with each other, and one of them is fitted with a cap to form an empty room. In this case, if the resin is filled from the side where the cap is not attached and cured similarly, the pair of housing sealing members cannot be separated. Means 6 When the hardened resin is broken and forcedly opened, the resin is transparent so that it can be easily recognized. Before being forcibly opened, the resin is transparent, so that when viewed from above, the opposite side appears to penetrate. However, when the resin is forcibly opened, the resin is broken inside the through-hole, and it becomes difficult for light to pass through the damaged portion, and the damage can be recognized. Means 7 On the other hand, the pair of housing sealing members may be made of a transparent resin while the resin is made transparent. In this case, it is easy to recognize from the outside whether or not the resin is damaged on the way. Means 8 Further, the above-mentioned casing sealing member is applicable to various game machines, and is applied to a pachinko machine as an example of a gaming machine, and the casing sealing member can be viewed from the back side of the pachinko machine. To be arranged in Pachinko machines are frequently opened during business hours, and the back side is visible. For this reason, fraud can be prevented by the case sealing member being located at a position visible from the back side. In a gaming machine such as a pachinko machine, there is a possibility that an IC recording a game program corresponding to a game content is accommodated in a control box and illegally rewriting the content of the IC is performed. Therefore, by applying the casing sealing member of the present invention to the control box, fraud can be prevented beforehand. Means 9 In addition, when the gaming machine is a slot machine, and the casing sealing member is applied to a control box of the gaming machine, the control box is disposed inside or on the back side of the slot machine, and the slot machine is opened. The housing sealing member is arranged at a position where the housing sealing member can be easily visually recognized. The slot machine is also frequently opened during business hours, and its back side is visible. For this reason, fraud can be prevented by the case sealing member being located at a position visible from the back side. Means 10 In addition, when the gaming machine is a pachi-lot, and this housing sealing member is applied to a control box of the gaming machine, the control box is disposed inside or on the back side of the pachi-lot, and when the pachi-lot is opened. The housing sealing member is arranged at a position where it can be easily viewed. A pachilot is a game machine having both features of a pachinko machine and a slot machine for performing picture matching using a fixed number of pachinko balls instead of medals. Such a pachilot is also frequently opened during business hours and its back side is visible. For this reason, fraud can be prevented by the case sealing member being located at a position visible from the back side. Various curing agents such as resin, adhesive, and putty can be used. As described above, the present invention can provide a gaming machine employing a control box which is sealed with a curable resin only and does not require metal fittings. Further, according to the invention relating to the means 1, a closed space can be formed on one side to prevent the resin to be filled from leaking. Further, according to the invention relating to the means 2, it is possible to provide a configuration in which the connecting portion is extended to the cylindrical side while creating a closed space. Further, according to the invention relating to the means 3, since the second through hole as the air hole is formed, the resin can be easily filled in the closed space. Further, according to the invention relating to the means 4, it is possible to cope with a closing method in a direction approaching from the side. Further, according to the invention relating to the means 5, the shape can be simplified. Further, according to the invention according to the means 6, it is possible to make the resin transparent so that an illegal act can be easily detected. Further, according to the invention of the means 7, since the casing sealing member is also formed of a transparent resin, it is possible to easily detect an illegal act. Furthermore, means 9
According to the invention, the pachinko machine can be visually recognized from the back side in the game area and is frequently opened even during business hours, so that it is easy to see, and it is found early to minimize loss due to fraud. And prevent fraud. Further, according to the invention according to the means 10, since the slot machine can be visually recognized when the slot machine is opened while being arranged inside the slot machine, it is possible to find out at an early stage and minimize a loss due to fraud. It is possible to prevent fraud. Further, according to the invention relating to the means 11,
Since it can be visually recognized when the pachilot is opened while being placed inside the pachilot, it is possible to detect the pachilot early and minimize the loss due to fraud and prevent fraud. Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a plan view and a bottom view of a control box of a gaming machine according to an embodiment of the present invention. In FIG. 1, a control box 10 having a substantially rectangular housing comprises a lid 11 and a housing main body 12. The lid 11 and the housing main body 12 are rotatably connected by a hinge 13 formed on one long side. On the other long side, four pairs of housing sealing members 20 and 30 are formed side by side. That is, the four housing sealing members 20 are formed on the lid 11 side, and the four housing sealing members 30 are formed on the housing main body 12 side. Each of the housing sealing members 20 and 30 is a bar-shaped member 2 that is relatively easily damaged.
The lid 11 and the housing main body 12 are connected to each other through the first and the first 31. The housing sealing member 20 is formed in a cylindrical shape as a whole as shown in FIG. However, the inside of the cylinder is formed with a plate-like portion 22 so as to temporarily partition the upper portion. A through-hole 23 is formed at the center of the plate-like portion, and a shallow plate portion 24 is formed by a cylindrical short wall rising upward from the periphery of the plate-like portion 22. Further, a cylindrical peripheral wall extends below the peripheral edge of the plate-like portion 22 to form a cylindrical portion 25. However, a part of the peripheral wall of the cylindrical portion 25 is cut, and a slit 26 that is continuous in the axial direction is formed. On the other hand, as shown in FIG. 4, the casing sealing member 30 has two plate-like portions 32, 3 which can be inserted into the tubular portion 25.
3 and a connecting wall 34. A through hole 35 is formed at the center of the upper plate portion. This connecting wall 3
4 connects the plate-like portions 32 and 33, and
When it is accommodated in the cylindrical portion 25 together with the cylindrical portions 2 and 33, it is formed at a position so as to close the slit 26. Further, the rod-shaped member 31 extends from an intermediate position in the vertical direction on the outer peripheral surface of the connecting wall 34. As shown in FIG. 5, the casing sealing members 20 and 30 are united when the lid 11 and the casing main body 12 are rotated about the hinge 13 and closed from the open state. That is, the housing sealing member 3 waiting on the housing body 12 side
The housing sealing member 20 on the side of the lid 11 is covered from above, and the two plate portions 32 and 33 enter the cylindrical portion 25.
At this time, the rod-shaped member 31 of the housing sealing member 30 enters the slit 26 formed in the housing sealing member 20 and does not interfere. When both are combined, a closed space (hardener reservoir) is formed in the cylindrical portion 25 except for the upper through holes 23 and 35 as shown in FIG. here,
When the curable resin is poured from the upper shallow plate portion 24, the resin enters the closed space via the through holes 23 and 35.
Therefore, when the resin cures, the cross-section becomes D-shaped, so that the plate portion 22 and the plate portion 32 cannot be separated. As a result, the casing sealing members 20 and 30, and furthermore, the casing main body 12 and the lid 11 become immovable, and the control box 10 is sealed. Note that various types of curable resins can be used, and an ultraviolet curable resin that cures by irradiating ultraviolet rays can also be used. If it is necessary to open the control box 10 as necessary, one or both of the bar members 21 and 31 are damaged. Then, when closed again, resin is poured into the other pair of housing sealing members 20 and 30 from the shallow plate portion 24 to be sealed. In this way, it is possible to seal up to four times in the embodiment shown in FIGS. In the above-described embodiment, the slit 26 is formed in the cylindrical portion 25 so as not to interfere with the rod-shaped member 31. However, as shown in FIG. 7, it is also possible to use only the opening below the cylindrical portion 25 without forming the slit 26. In this case, regarding the housing sealing member 30,
The two plate-shaped portions 32, 33 are supported by being separated by two connecting walls 34, and the bar-shaped member 31 is bent laterally after protruding downward from the lower plate-shaped portion 33. It is formed so as to be extended. Even in this case, the housing sealing member 30
Are waiting together with the housing body 12, and when the housing sealing member 20 rotates together with the lid 11, the two plate portions 32, 33 and the connecting walls 34, 34 are inserted into the cylindrical portion 25 from below. As a result, a closed space (hardener reservoir) is formed in the cylindrical portion 25. Then, when the curable resin is poured from the upper shallow plate portion 24, the resin is hardened inside, and the plate-shaped portions 22, 32 are connected so as not to be separated. FIG. 8 shows an example of a simpler configuration.
Also, the configuration shown in FIG. 9 can be adopted. In this example, the housing sealing members 120 and 130 are both
1, 131 are formed in a shallow dish shape in which through holes 122, 132 are formed, and extend from the housing main body and the lid so that the bottom surfaces face each other. Then, a cap 133 is attached to the lower housing sealing member 130 at the time of sealing so as to close the opening. In this manner, the lower housing sealing member 1
A closed space is formed in the upper housing sealing member 1.
When the curable resin is filled from step 20, the resin is cured in a D-shaped cross section as in the above-described embodiment, and the two housing sealing members 120 and 130 are connected to seal the control box. 10 and 11 schematically show housing sealing members 220 and 230 according to another embodiment. The previous example,
The two housing sealing members 2 are arranged in the through direction of the through holes 23 and 35.
In the present embodiment, housing sealing members 220 and 230 approach and separate from each other in a direction perpendicular to the opening direction of the through-hole, whereas 0 and 30 approach and separate from each other. FIG. 12 is a perspective view of the housing sealing member 220 cut out. In the figure, the housing sealing member 220 has a substantially circular cross section, while the housing sealing member 220 has a substantially semi-cylindrical cross section. The housing sealing member 20 has a cylindrical lower portion and opens downward, whereas the housing sealing member 220 closes the lower portion and opens a semi-cylindrical flat surface to form an empty room. are doing. The housing sealing member 220 has a plate-shaped portion 222 that separates the upper shallow plate portion 224 and the lower empty room 225, and the plate-shaped portion 222 has a through hole 223 formed therein. On the other hand, the pair of housing sealing members 230
As shown in FIG. 3, plate-like portions 232 and 233 which can be inserted from the above-mentioned opening surface and which are held at an interval vertically, and a connecting wall 2 which can coincide with the opening surface and close the opening portion
34. The plate portions 232 and 233 are formed in a substantially semi-cylindrical shape that matches the cross section of the housing sealing member 220, and a through hole 235 is formed in the upper plate portion 232. Assuming that the housing body and the lid (not shown) are slidably mounted, the housing sealing member 220 is attached to the housing body.
Is formed, and the housing sealing member 230 is formed on the lid. Then, when the lid slides along the housing main body, the housing sealing member 230 approaches the opening of the empty space in the housing sealing member 220, and finally the plate portions 232, 233 and the connecting wall. 234 are accommodated in the empty room. In this state, the empty room has through holes 223 and
Enclosed all around except 235, the housing sealing member 2
When the curable resin is filled in the upper shallow plate portion 224 in 20, the empty room is filled with the resin via the through holes 223 and 235 and hardened. When the resin cures, a resin in the vertical direction penetrating through holes 223 and 235 is formed, and the resin must be damaged in order to open the control box. Thus, the control box is substantially sealed. In the above example, the housing sealing members 20, 30, 120, 130, 220, 2
Although 30 colors are not specified, as an example, the entirety may be formed of a transparent resin. When formed of a transparent resin, the resin cured inside can be visually recognized from the outside, and in the case where the resin is forcibly opened after being sealed, the damage state of the internal resin becomes obvious at a glance. Therefore, fraud can be prevented. Similarly, the curable resin may be made transparent. When the transparent resin is hardened, the lower plate-like portion is normally visible from above the shallow dish portion through the through hole. However, when the sealing is forcibly released, the resin is damaged on the way, so that the lower plate-shaped portion is difficult to see. In addition, when the resin is filled through the through hole, an air hole may be formed so as to facilitate the filling. For example, while each through-hole in each of the above-described embodiments is formed at the center of the plate-shaped portion, the second through-hole serving as an air hole is preferably formed at the periphery of the plate-shaped portion. In this way, when the resin is filled from the central through hole, the air in the closed space or the empty room escapes from the peripheral through hole to the outside, so that the resin is easily filled. FIG. 14 is a rear view of the pachinko machine, in which a control box to which the housing sealing member is applied is mounted so as to be visible from the rear side. A rectangular box-shaped control box 70 is mounted on the back side of the pachinko machine 60. Here, in the control box 70, the lid and the housing can be opened and closed by a hinge mechanism formed on one side of the long piece, and the housing sealing member is adopted on both short sides. That is, the housing sealing member 30 of the lid and the housing sealing member 20 of the housing are formed on the short sides of the lid and the housing, respectively, in four pairs, and can be sealed. Of course,
An opening can be provided as needed. As shown in the figure, since the pachinko machine 60 is disposed at a position where the pachinko machine 60 can be directly viewed from the rear side, the pachinko machine 60 can be easily viewed when the pachinko machine 60 is opened for maintenance. Therefore, if the hardened resin is damaged to modify the inside of the control box 70, it will be found immediately at the next maintenance. FIG. 15 shows the back of a slot machine (pachislot) 80. A rectangular box-shaped control box 90 is also mounted on the back side of the slot machine 80. Here, the cover box and the housing of the control box 90 can be opened and closed by a hinge mechanism (not shown), and the housing sealing member is adopted on both short sides. That is, the housing sealing member 20 of the lid and the housing sealing member 30 of the housing main body are respectively formed on the short sides of the lid and the housing in four pairs, respectively, and can be sealed. It can also be done. 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 casing sealing member can be easily visually recognized. Therefore, if the cured resin is damaged to modify the inside of the control box 90, it will be found immediately at the next maintenance. Although not shown, the present invention can be similarly applied to a pachilot. A pachinko-lot uses pachinko game balls instead of medals. For example, five pachinko balls correspond to one medal and can be enjoyed in the game. As described above, the housing body 12 and the lid 11 constituting the control box 10 are provided with the housing sealing member 30 and the housing sealing member 20. A plate-like portion 32 having a through-hole 35 formed in a central portion is formed in the housing sealing member 30, and a plate-like portion 22 having a through-hole 23 is formed in the central portion also in the housing sealing member 20. . A shallow dish portion 24 as a resin pool is formed on the side of the plate portion 22, and a plate portion 33 and a connecting wall 34 which form a closed space together with the cylindrical portion 25 on the plate portion 32 side. And form a hardener pool. When the curable resin is filled from the side of the shallow dish portion 24 with the plate portions 22 and 32 in contact with each other, the resin hardens into a D-shaped cross section, and the plate portions 22 and 32 are integrally separated. You will not be able to do it.
