Description

  The present invention relates to a gaming machine sealing member that seals a sealing target portion located in a deep portion of the sealing hole by fitting into a sealing hole provided in the gaming machine, and a game for manufacturing the gaming machine sealing member. The present invention relates to a method for manufacturing a sealing member for a machine and a sealing structure for a gaming machine that seals a sealing target portion using the sealing member for a gaming machine.

  Gaming machines can be the subject of various fraudulent activities. For example, various board units are housed inside a housing of a gaming machine, and a storage device (usually a ROM) in which a program for controlling the gaming machine is recorded is mounted on these board units. However, there is known an illegal act of replacing this storage device with a forged one (so-called forged ROM). In order to prevent this kind of fraudulent activity, each maker of gaming machines has a structure in which the equipment to be fraudulent such as a board unit is housed in a case (board case), and the board case is closed. The location where the screws are screwed (sealing target location) is sealed with a sealing member to prevent unauthorized access to the sealing target location, and if unauthorized access is made to the sealing target location, Measures are taken to ensure that traces remain on the sealing member.

  As described above, various types of sealing members for gaming machines have been proposed so far, which are used for sealing the substrate case of the gaming machine. For example, as shown in FIG. 2 of Patent Document 1, the present applicant has a cylindrical insertion in which a sealing target portion (sealing target portion) is inserted into a sealing hole (sealing hole) provided in the inner part. A portion 11 (sealing hole insertion portion) and a lid portion 12 (head portion having a flange portion) arranged on the base end side of the sealing hole insertion portion 11 for covering the sealing hole are connected via a connecting portion 13. Then, a sealing member 1 (sealing member) having a structure in which the base end of the sealing hole insertion portion 11 is connected only in a partial section α in the circumferential direction is proposed. An engagement portion 111 for engaging with the inner peripheral portion of the sealing hole is provided on the outer peripheral portion of the sealing hole insertion portion 11.

  In the sealing member 1 of Patent Document 1, as shown in FIG. 4 of the same document, an unauthorized insertion tool T (unauthorized instrument) is inserted into a gap S between the inner peripheral surface of the sealing hole 21 and the outer peripheral surface of the sealing member 1, When the engaging portion 111 is pushed inward by the tip of the unauthorized device T to try to release the engagement of the engaging portion 111, the connecting portion 13 is broken by the force applied from the unauthorized device T to the flange portion 12. Is assumed. In this way, if an unauthorized access is made to the sealing target portion A sealed by the sealing member 1 of Patent Document 1, a trace remains on the connecting portion 13 or the like of the sealing member 1. Therefore, by checking the presence or absence of the trace, an unauthorized access is made. It is possible to confirm the presence or absence of.

Japanese Patent No. 5447901

  However, in the sealing member 1 of Patent Document 1, since the connecting portion 13 intended to leave the trace of the unauthorized access is locally provided in a narrow range, the range where the trace of the unauthorized access is formed is also around the connecting portion 13. Easy to stay in a narrow range. In addition, the connecting portion 13 is provided at a location on the inner side of the flange portion 12 that is relatively hard to see. Therefore, in the sealing member 1 of Patent Document 1, even if the connecting portion 13 is broken at the time of unauthorized access, if the broken portion is adhered with an adhesive or the like, it becomes difficult to notice the trace. I was afraid.

  The present invention has been made in order to solve the above-mentioned problems, and traces of unauthorized access are formed in a wide range, it is difficult to erase the traces, and the traces can be found more reliably. By doing so, it is possible to provide a gaming machine sealing member capable of preventing fraudulent acts on the gaming machine. It is also an object of the present invention to provide a method for manufacturing a sealing member for a gaming machine for manufacturing the sealing member for a gaming machine. Furthermore, it is also an object of the present invention to provide a sealing structure for a gaming machine, which seals a sealing target portion using this sealing member for gaming machine.

The above problems are
A game machine sealing member for sealing a sealing target portion located in the inner part of the sealing hole by fitting the sealing hole provided in the gaming machine,
A portion for insertion into the sealing hole, having an engaging portion for engaging with an engaged portion provided in the sealing hole on the outer peripheral portion, a sealing hole inserting portion made of a synthetic resin material,
A portion for covering the gap between the outer peripheral surface of the sealing hole insertion portion and the inner peripheral surface of the sealing hole, provided on the proximal end side of the sealing hole insertion portion, a flange portion made of a synthetic resin material,
A convex portion provided on the outer peripheral portion of the sealing hole insertion portion, which has an edge capable of concentrating stress on a portion contacting the flange portion,
Equipped with
This is solved by providing a sealing member for a gaming machine, in which the flange portion is formed of a synthetic resin material having lower strength than the sealing hole insertion portion.

  Here, the “strength” in “the flange portion is formed of a synthetic resin material having a lower strength than the sealing hole insertion portion” means “Izod impact strength”. Synthetic resin materials for forming the flange portion and the sealing hole insertion portion include methyl methacrylate resin (PMMA), polypropylene (PP), polystyrene (PS), and acrylonitrile-butadiene-styrene copolymer synthetic resin (ABS). Alternatively, a thermoplastic resin such as polycarbonate (PC) is exemplified. Table 1 below shows these synthetic resin materials arranged in the ascending order of Izod impact strength. However, the Izod impact strength in Table 1 below is a general value until it gets tired, and the value of each thermoplastic resin increases or decreases depending on the specific specifications of the thermoplastic resin, and the rank of each thermoplastic resin changes. Sometimes. Among these synthetic resin materials, the sealing hole insertion portion is formed by a material having a relatively high Izod impact strength, and the flange portion is formed by a resin having a lower Izod impact strength than the resin in which the sealing hole insertion portion is formed.

  Like this configuration, by forming the flange portion with a synthetic resin material having a lower strength than the sealing hole insertion portion, an illegal device is provided in the gap between the inner peripheral surface of the sealing hole and the outer peripheral surface of the gaming machine sealing member. When an unauthorized access is attempted to the sealing target part by inserting the plug or the like, traces such as breakage and whitening are formed in a wide area in the flange portion. In particular, in a relatively weak and brittle flange portion, stress easily concentrates in the vicinity of the portion that comes into contact with the sealing hole insertion portion, which has a relatively high strength, and cracks and the like that originate in the vicinity of the portion where the stress concentrates are formed. Can be made easier. Therefore, a trace that is difficult to erase with an adhesive or the like can be left on the gaming machine sealing member. In addition, since the trace of the unauthorized access remains on the easily visible flange portion even when the gaming machine sealing member is fitted in the sealing hole, the trace of the unauthorized access can be easily found.

  In the sealing member for a gaming machine of the present invention, the outer edge of the sealing hole insertion portion, the portion that contacts the flange portion (hereinafter, referred to as "base end outer peripheral portion of the sealing hole insertion portion"), has an outward edge. It is also preferable to repeatedly provide a plurality of convex portions having a.

  This is because, as already mentioned, when the flange part is made of a synthetic resin material having lower strength than the sealing hole insertion part, the sealing hole insertion part (relatively low strength and fragile part) A crack or the like starting from the vicinity of the part that contacts the high strength part) is likely to be formed.With such a configuration, an unauthorized device is inserted into the gap between the inner peripheral surface of the sealing hole and the outer peripheral surface of the gaming machine sealing member. If an unauthorized access to the sealing target is attempted, the stress is more likely to concentrate on the portion of the flange portion that abuts the outward edge, and the flange portion is exposed to the outward direction. It is possible to further facilitate the occurrence of cracks and the like starting from the portion that comes into contact with the edge of the. Therefore, when an unauthorized access is attempted, it is possible to make it more difficult to erase and leave a more conspicuous trace on the flange portion.

In the gaming machine sealing member of the present invention, in the case of providing a plurality of convex portions having outward edges on the base end outer peripheral portion of the sealing hole insertion portion,
With the plurality of convex portions embedded in the back surface of the flange portion (the surface connected to the sealing hole insertion portion),
Smoothly form the front surface (the surface opposite to the surface connected to the sealing hole insertion part) of each of the convex parts,
It is preferable to provide the outward edges on the rear surface side of each of the convex portions.

  This is because, if an edge is formed on the front surface side of the plurality of convex portions, a pressing force applied to the flange portion when the game machine sealing member is fitted into the sealing hole (when it is properly fitted). Traces such as breakage or whitening may easily occur on the flange portion even by the pressure. In this respect, like this configuration, the outward edge is not provided on the front surface side of the plurality of convex portions, but is provided on the back surface side of the plurality of convex portions, so that the game is performed with respect to the sealing hole. When the machine sealing member is fitted properly, the gap between the inner peripheral surface of the sealing hole and the outer peripheral surface of the game machine sealing member is not correct, while making sure that the flange does not have traces such as breakage or whitening. This is because when an unauthorized access to the sealing target is attempted by inserting a device or the like, it becomes possible to easily cause a trace such as breakage or whitening on the flange portion.

  In the gaming machine sealing member of the present invention, it is also preferable to provide a rib projecting toward the front surface side at the outer edge portion of the front surface of the flange portion.

  By adopting such a configuration, when an illicit device is inserted into the gap between the inner peripheral surface of the sealing hole and the outer peripheral surface of the game machine sealing member, the illegitimate device is the flange portion of the sealing hole insertion portion. The rib comes into contact with a rib that is farther away from a portion that contacts the outer peripheral portion of the base end (hereinafter, also referred to as "root portion of flange portion"). Therefore, when an unauthorized device is inserted into the gap between the inner peripheral surface of the sealing hole and the outer peripheral surface of the gaming machine sealing member, a large force is easily applied to the root portion of the flange portion, and the base portion of the flange portion is easily applied. It becomes possible to easily leave traces such as breakage and whitening.

  The manufacturing method of the sealing member for gaming machine of the present invention is not particularly limited, but it is preferable to manufacture it by two-color molding of the sealing hole insertion portion and the flange portion.

  This is because, for example, when the separately molded sealing hole insertion portion and the flange portion are later bonded with an adhesive or the like to manufacture the gaming machine sealing member, impurities are added to the bonded portion. There is a risk that the adhesive may be unevenly applied, and the adhesive may be unevenly applied, so that not only the appearance of the sealing member for a gaming machine may be deteriorated, but also impurities and unevenness of application may be mistaken as a trace of unauthorized access. . In addition, the flange portion may be damaged when the flange portion is bonded to the sealing hole insertion portion. In this respect, by forming the sealing hole insertion portion and the flange portion by two-color molding as in the above configuration, the sealing hole insertion portion and the flange portion can be neatly integrated without damaging the flange portion. Because it will be possible.

It is supposed to be served. The number of credits of medals increases when the number of credits of medals does not reach the upper limit value when a medal is inserted into the medal insertion slot 11 or when a medal is paid out by winning.

  FIG. 2 is a diagram of the rotating-type gaming machine 10 with the front door 10b opened, as viewed from the front upper right. As shown in FIG. 2, the rotating body type gaming machine 10 includes a box-shaped main body 10a having an open front, and a front door 10b attached to the front side of the main body 10a in an openable and closable manner. Various devices are housed inside the game machine housing. In the following, the case body 10a and the front door 10b may be collectively referred to as "cases 10a and 10b".

In this embodiment, the main control board unit 30, the sub control board unit 31, the liquid crystal unit 32, the power supply unit 33, the connector unit 34, the reel unit 35, the hopper unit 36, etc. are housed inside the housings 10a, 10b. There is. Of these units 30 to 36, the liquid crystal unit 32 and the connector unit 34 are attached to the inner surface side (back surface side) of the front door 10b. On the other hand, the main control board unit 30, the sub control board unit 31, the power supply unit 33, the reel unit 35, and the hopper unit 36 are attached to the inner surface side of the housing body 10a. Reel window 10b ₁ described above, it is provided in a substantially rectangular shape in the middle portion slightly above inner portion of the front door 10b.

  The main control board unit 30 includes a control board (main control board) that performs basic control in the game, such as winning a lottery and winning determination. The sub-control board unit 31 includes a control board (sub-control board) that controls the effects in the game, such as effects by light-emitting lamps and sounds. The liquid crystal unit 32 is provided with a control board (video board) that performs control related to effects by the video displayed on the liquid crystal display 16 (see FIG. 1). The power supply unit 33 includes a control board (power supply board) that supplies electric power to each device in the spinning-type gaming machine 10. The connector unit 34 includes a control board (mediation board) that mediates a cable connected to a specific device.

The hopper unit 36 collects the medals inserted into the medal insertion slot 11 (see FIG. 1) and sends the medals to the medal payout outlet 12 (see FIG. 1) based on a signal from the main control board unit 30. A control board (a hopper control board) for controlling the operation is provided.

  Any of the various control boards provided in these units 30 to 36 can be the target of unauthorized access. In particular, on the control board (main control board) of the main control board unit 30, a storage device (ROM) in which a program for performing basic control in the spinning-type gaming machine 10 is recorded is mounted, There is a person who tries to illegally modify the spinning-reel type gaming machine 10 by replacing this storage device with a counterfeit one so that a big hit is always made when a specific operation is performed during a game. Therefore, in a gaming machine such as the spinning drum type gaming machine 10, as shown in FIG. 3, the main control board 30a is housed and sealed in a board case 50 composed of a cover member 51 and a base member 52. Is being done. FIG. 3 is a diagram of a state in which the main control board 30a (control board) is housed in the board case 50 and sealed, as seen from the front upper right. The board case 50 accommodating the main control board 30a is usually attached to the housing body 10a (FIG. 2) via a holder member 60 arranged on the rear side thereof.

Specifically, as shown in FIG. 3, the cover 70 is inserted by screwing a fixing tool 70 such as a screw into a sealing hole α provided in the substrate case 50 (the cover member 51 in the present embodiment). After fixing the member 51 and the base member 52 in the closed state, the game machine sealing member 100 is fitted into the sealing hole α. The gaming machine sealing member 100 fitted in the sealing hole α is in a state in which the outer peripheral portion thereof is engaged with the engaged portion α ₃ (FIG. 4) in the inner portion of the sealing hole α. Therefore, unless the game machine sealing member 100 is destroyed or forcedly deformed, a state in which the fixture 70 in the inner part of the sealing hole α (sealing target portion α ₁ ) cannot be accessed appears. In other words, by confirming whether or not the gaming machine sealing member 100 has a trace such as breakage or whitening, whether or not the sealing target portion α ₁ is illegally accessed (the substrate case 50 is illegally opened). It has become possible to judge whether or not it has been done. That is, the gaming machine sealing member 100 functions as a seal. The control boards in the units 31 to 36 other than the main control board unit 30 can be housed and sealed in a board case similar to the board case 50 described above.

  The board case 50 (the cover member 51 and the base member 52) is usually made of a transparent material so that it can be confirmed from the outside of the board case 50 whether or not an abnormality has occurred in the board case 50. Usually, it is formed of a synthetic resin material. As a material for forming the substrate case 50, methyl methacrylate resin (PMMA), polypropylene (PP), polystyrene (PS), acrylonitrile-butadiene-styrene copolymer synthetic resin (ABS), polycarbonate (PC), or the like. The thermoplastic resin of. These thermoplastic resins are similar to the thermoplastic resins forming the gaming machine sealing member 100, but the substrate case 50 includes the gaming machine sealing member 100 (especially a sealing material formed of a high-strength synthetic resin material). It is preferable to use a synthetic resin material having a higher strength than the hole insertion portion 110). ABS and PC are preferable as the synthetic resin material forming the substrate case 50, and PC is particularly preferable because it has excellent strength.

  The present invention relates to the game machine sealing member 100. Up to this point, a case where the gaming machine sealing member 100 is fitted into a portion (sealing hole α) of the substrate case 50 in which the fixing member 70 for fixing the cover member 51 and the base member 52 in the closed state is inserted. However, the place where the game machine sealing member 100 of the present invention is fitted is not limited to this. For example, the gaming machine sealing member 100 of the present invention is fitted into a hole-shaped portion through which a fixture for fixing the substrate case 50 (cover member 51 or base member 52) to the holder member 60 in FIG. 3 is inserted. Good. Further, the place where the sealing hole α is provided does not need to be the portion through which the fixing tool is inserted and the substrate case 50 as long as it is a portion that needs to be sealed to prevent unauthorized access.

2. Sealing member for gaming machine of the present invention The sealing member 100 for gaming machine of the present invention will be described in more detail. In the following, the gaming machine sealing member 100 of the present invention will be described by taking four embodiments from the first embodiment to the fourth embodiment as examples. However, the technical scope of the gaming machine sealing member 100 of the present invention is not limited to these embodiments, and the embodiments can be appropriately changed within a range not impairing the gist of the invention.

2.1 Sealing Member for Gaming Machine of First Embodiment First, the sealing member 100 for gaming machine of the first embodiment will be described. FIG. 4 is a perspective view showing a state in which the gaming machine sealing member 100 of the first embodiment is fitted into the sealing hole α. FIG. 5 is a perspective view of the gaming machine sealing member 100 of the first embodiment, showing a state (a) viewed from the front upper right and a state (b) viewed from the rear upper right, respectively. FIG. 6 shows a state in which the gaming machine sealing member 100 of the first embodiment is cut along a plane parallel to the yz plane including the center line of the gaming machine sealing member 100 (the center line parallel to the y-axis direction). It is sectional drawing which showed. FIG. 7 is a view of the gaming machine sealing member 100 of the first embodiment as viewed from the front side (the negative side in the y-axis direction), in which (a) a state in which a tear β is not formed in the head 120, and ( FIG. 7B is a diagram showing a state in which a split β is generated in the head 120. 4, 5, and 7, only the sealing hole insertion portion 110 is shown by hatching in order to easily distinguish the sealing hole insertion portion 110 and the head portion 120 in the gaming machine sealing member 100 in the drawings. ing.

2.1.1 Basic Configuration As shown in FIG. 4, the game machine sealing member 100 is fitted into the sealing hole α so as to seal the sealing target portion α ₁ located at the back of the sealing hole α. It has become.

The game machine sealing member 100 according to the first embodiment includes a sealing hole insertion portion 110 and a head 120. Both the sealing hole insertion portion 110 and the head portion 120 are made of a synthetic resin material. The sealing hole insertion portion 110 is a portion that is inserted into the sealing hole α from the tip side (the end on the positive side in the y-axis direction in FIG. 4). An engagement portion 111c is provided on the outer peripheral portion of the sealing hole insertion portion 110. When the gaming machine sealing member 100 is fitted into the sealing hole α, the engaging portion 111c engages with the engaged portion α ₃ in the inner portion of the sealing hole α, and the gaming machine sealing member 100 is opened. It cannot be pulled out to the front side. On the other hand, the head portion 120 is a portion provided on the base end side (the end portion on the y axis direction negative side in FIG. 4) side of the sealing hole insertion portion 110. In the sealing hole insertion portion 110 of the first embodiment, the head portion 120 includes a central portion 121 that overlaps with a base end surface of the sealing hole insertion portion 110 (a closing portion 112 described later) and a base end outer peripheral portion of the sealing hole insertion portion 110. The flange portion 122 is provided so as to project outward.

In the state where the gaming machine sealing member 100 is fitted into the sealing hole α, if an unauthorized access is made to the sealing target portion α ₁ , the outer peripheral surface of the flange portion 122 and the outer peripheral surface of the sealing hole insertion portion 110 and the sealing hole α are It is necessary to insert an illegal instrument such as a flat-blade screwdriver into the gap between the inner peripheral surface and illegally release the engagement of the engaging portion 111c, or to make a hole in the game machine sealing member 100 from the central portion 121 of the head 120. There is. In this respect, the flange portion 122 of the head portion 120 has a gap from the front side of the sealing hole α so that an unauthorized instrument is not inserted into the gap between the outer peripheral surface of the sealing hole insertion portion 110 and the inner peripheral surface of the sealing hole α. In addition to covering, if an illegal instrument is inserted into the gap, as shown in FIG. 7 (b), it becomes a part for leaving a crack β, a chip, a trace of breakage, whitening, etc. ing. In addition, the central portion 121 has traces (breakage marks, whitening, etc.) when a hole or the like is opened in a portion other than the flange portion 122 of the gaming machine sealing member 100 (the central portion of the gaming machine sealing member 100). It is a part to leave.

That is, the sealing hole insertion portion 110 mainly inserts the gaming machine sealing member 100 into the engaged portion α ₃ in the inner portion of the sealing hole α so that the gaming machine sealing member 100 is not pulled out from the sealing hole α. In contrast to having a function of engaging with each other, the head 120 mainly has a function of producing a trace of unauthorized access to the sealing target portion α ₁ . Therefore, the head portion 120 is formed of a material (synthetic resin material) having a lower strength (Izod impact strength) than the sealing hole insertion portion 110. The synthetic resin material that forms the head portion 120 and the sealing hole insertion portion 110 is not particularly limited as long as it has the above relationship in strength, but is formed of a transparent (including colored and transparent) synthetic resin material. It is preferable. Thereby, even when the gaming machine sealing member 100 is fitted in the sealing hole α, it is possible to visually check whether there is any abnormality in the sealing target portion α ₁ from the front side of the sealing hole α to the inner side of the sealing hole α. It becomes possible to confirm.

  In this respect, synthetic resin materials having transparency are generally methyl methacrylate resin (PMMA), polypropylene (PP), polystyrene (PS), acrylonitrile-butadiene-styrene copolymer synthetic resin (ABS). ) And thermoplastic resins such as polycarbonate (PC). The strength (Izod impact strength) of these thermoplastic resins is generally as shown in Table 1 above. Therefore, the strengths of PMMA, PP, PS, ABS and PC are in the order shown in Table 1, and the synthetic resin material forming the sealing hole insertion portion 110 and the head portion 120 is selected from Table 1. For example, That is, when the sealing hole insertion portion 110 is formed of PC, the head portion 120 is formed of PMMA, PP, PS or ABS. When the sealing hole insertion portion 110 is made of ABS, the head 120 is made of PMMA, PP or PS. Furthermore, when the sealing hole insertion portion 110 is formed of PS, the head portion 120 is formed of PMMA or PP. Furthermore, when the sealing hole insertion portion 110 is formed of PP, the head portion 120 is formed of PMMA.

  However, as will be described later, when the sealing hole inserting portion 110 and the head portion 120 of the gaming machine sealing member 100 are two-color molded, a synthetic resin material for forming the sealing hole inserting portion 110 and the head portion 120 is used. Consider the melting point. That is, in two-color molding in which different materials are molded in two steps using a common mold, a member formed of a synthetic resin material having a high melting point is first molded, and then a synthetic resin having a low melting point is used. This is because it is necessary to later mold the member formed on the side of the system material. In this respect, in general, the higher the melting point of a thermoplastic resin, the higher the strength (Izod impact strength), and the relationship between the melting point of each thermoplastic resin and the strength relationship of each thermoplastic resin. Are roughly in agreement.

  The sealing hole insertion portion 110 and the head portion 120 of the gaming machine sealing member 100 are provided in an integrated state with each other. The method of integrating the sealing hole insertion portion 110 and the head portion 120 is not particularly limited, and for example, the separately formed sealing hole insertion portion 110 and the head portion 120 are later bonded by an adhesive or the like to be integrated. You may make it. However, the work of adhering the sealing hole insertion portion 110 and the head portion 120 is normally performed by taking out the components (sealing hole insertion portion 110 and the head portion 120) one by one, and therefore, they are formed separately. In the method of adhering the sealing hole insertion portion 110 and the head 120 to each other, there is a risk that impurities or the like may enter the bonding portion between the sealing hole insertion portion 110 and the head 120, or that coating unevenness may occur in the adhesive or the like. . For this reason, not only the appearance of the gaming machine sealing member 100 may be deteriorated, but also impurities, coating unevenness, and the like may be erroneously recognized as marks of unauthorized access. In particular, in the gaming machine sealing member 100 of the present embodiment, as will be described later, a configuration in which the sealing hole insertion portion 110 and the head portion 120 are of different colors is also adopted, so that the sealing hole insertion portion 110 and the head portion 120 are Where color is also important, as described above, if impurities are mixed in the bonding portion between the sealing hole inserting section 110 and the head 120, the color of the sealing hole inserting section 110 or the head 120 may be adversely affected. . In addition, the head part 120 (particularly the flange part 122) may be damaged when the sealing hole insertion part 110 and the head part 120 are bonded together.

  Therefore, it is preferable that the sealing hole insertion portion 110 and the head portion 120 be integrated with each other by two-color molding. As a result, it becomes possible to integrate the sealing hole insertion portion 110 and the head portion 120 without using an adhesive agent and without manual work. Therefore, it is possible to prevent impurities from being mixed in the boundary portion between the sealing hole insertion portion 110 and the head portion 120 and uneven coating of the adhesive at the boundary portion. Therefore, not only the original colors of the sealing hole insertion section 110 and the head 120 can be seen, but also the sealing hole insertion section 110 and the head 120 can be separated without damaging the head 120 (flange 122). It also becomes possible to integrate it neatly. Also in the gaming machine sealing member 100 of the first embodiment, the sealing hole insertion portion 110 and the head portion 120 are integrated with each other by two-color molding. Specifically, after injecting PC or ABS into the first mold to mold the sealing hole insertion part 110, a part of the first mold (a part connected to the base end part of the sealing hole insertion part 110) ) Is switched to the second mold, and PMMA is injected into the second mold to mold the head 120, so that the sealing hole insertion portion 110 and the head 120 are integrated with each other. The sealing member 100 is obtained.

As described above, since the head portion 120 including the flange portion 122 is formed of a synthetic resin material having a lower strength than the sealing hole insertion portion 110, the inner peripheral surface of the sealing hole α and the sealing member 100 for gaming machine 100. When an unauthorized device is inserted into the gap between the outer peripheral surface and the unauthorized access to the sealing target portion α ₁ is attempted, the head 120 (particularly the flange 122) may be broken or whitened in a wide range. Traces will start to form. Therefore, it becomes possible to leave a trace that is difficult to erase with an adhesive or the like on the gaming machine sealing member 100. In addition, even when the gaming machine sealing member 100 is fitted in the sealing hole α, a trace of unauthorized access remains on the head 120 that is easily visible from the front side of the sealing hole α, and thus a trace of unauthorized access is generated. It also makes it easier to discover.

2.1.2 Special Remarks Hereinafter, with respect to the gaming machine sealing member 100 of the first embodiment, some items to be specially noted are listed.

(1) Regarding Colors of Sealing Hole Insertion Portion and Head Part It is preferable to select a transparent (including colored and transparent) synthetic resin material for forming the head part 120 and the sealing hole insertion part 110. Already mentioned. In this respect, it is preferable that both the head 120 and the sealing hole insertion portion 110 are colored and transparent, and the head 120 and the sealing hole insertion portion 110 have different colors. This is because, if the head 120 and the sealing hole insertion portion 110 have the same color (including the case where both are completely transparent), the flange portion 122 may be cracked or chipped due to unauthorized access. When a gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the sealing hole insertion portion 110 becomes directly visible from the front side of the sealing hole α, a crevice or a chip in the flange portion 122 is generated. The sealing hole insertion portion 110 of the same color as the flange portion 122 becomes visible through the portion where the crack occurs, and it may be difficult to notice that the flange portion 122 is cracked.

  In this respect, if the head portion 120 and the sealing hole insertion portion 110 are made to have different colors, as shown in FIG. 7B, when a crack β, a chip, or the like occurs in the head portion 120 such as the flange portion 122, the The seal hole insertion portion 110 located on the far side of the head 120 is seen in a color different from that of the head 120 through the portion where the crevice β or the like is generated, and the crevice β or the like is in a conspicuous state. The existence of cracks β and the like is not easily overlooked. Therefore, it becomes possible to easily find the trace of the unauthorized access (the crack β or the chip or the like generated in the head 120) and prevent the illegal action against the gaming machine. Since the sealing hole insertion portion 110 is formed of a synthetic resin material having a higher strength than the head portion 120, even if the head portion 120 is cracked β or chipped during an unauthorized access, the sealing hole insertion portion 110 is formed. It is highly possible that 110 does not have such cracks or chips. Examples of the coloring method of the head 120 and the sealing hole insertion portion 110 include a method of adding a coloring material such as a pigment to the molding material (transparent synthetic resin material) of the head 120 or the sealing hole insertion portion 110. .

  By the way, although the aspect which makes both the sealing hole insertion part 110 and the head 120 different in color by making it transparent is described above, the aspect which makes the sealing hole insertion part 110 and the head 120 different in color is described above. In addition, [1] a mode in which the sealing hole insertion portion 110 and the head 120 are both opaque and different colors, and [2] one of the sealing hole insertion portion 110 and the head 120 is opaque and the other is transparent. (Including not only colorless and transparent but also colored and transparent. The same applies to the following.) (However, the aspect in which the head 120 is colorless and transparent is excluded), and [3] the sealing hole insertion portion 110 and the head. There is a mode in which one of 120 is colorless and transparent and the other is colored and transparent.

However, in the above aspects [1] and [2], in the state in which the gaming machine sealing member 100 is fitted in the sealing hole α, the sealing target portion in the deep part of the sealing hole α from the front side of the sealing hole α It becomes difficult to visually confirm whether or not α ₁ is abnormal. Further, in the above aspect [3], when the sealing hole insertion portion 110 is colored and transparent and the head portion 120 is colorless and transparent, a crack β or a chip is formed in the flange portion 122 or the like during unauthorized access. In, the seal hole insertion portion 110 that is visible through a portion of the flange portion 122 or the like where the crack β or the chip is formed is large in the seal hole insertion portion 110 that is visible through a portion of the flange portion 122 or the like where the gap β or the chip is not formed. No difference can be seen, and the existence of crevices β, chips, etc. is easily overlooked. Furthermore, in the above aspect [3], when the sealing hole insertion portion 110 is colorless and transparent and the head 120 is colored and transparent, the sealing hole insertion exposed from the crevice β generated in the head 120 during unauthorized access is inserted. The portion 110 is transparent and is inconspicuous, and the presence of the crevice β, the chip, and the like is likely to be overlooked. For the above reasons, it is preferable that both the head 120 and the sealing hole insertion portion 110 are colored and transparent, and that the head 120 and the sealing hole insertion portion 110 have different colors.

  However, even if the sealing hole insertion section 110 and the head 120 are different in color, if they are similar in color, due to the crevice β or the chip or the like generated in the head 120 during unauthorized access, Even if the seal hole insertion portion 110 located on the back side can be seen, the inspector may not notice the difference in color, and the existence of the crack β or the chip may be overlooked. Therefore, it is preferable that the color of the head portion 120 be as different as possible from the color of the sealing hole insertion portion 110. In the gaming machine sealing member 100 of the first embodiment, the color of the head portion 120 and the color of the sealing hole insertion portion 110 are in a complementary color relationship.

  Here, “the color of the head 120 and the color of the sealing hole insertion portion 110 have a complementary color relationship” means that the color of the head 120 is a complementary color of the color of the sealing hole insertion portion 110 (in the hue ring of the Munsell system). , The color located exactly opposite to the position where the color of the sealing hole insertion section 110 is located. The color is not limited to the “correct complementary color of the color of the sealing hole insertion section 110” below. In the "complementary color relationship" in this specification, the color of the head 120 is within 90 ° on both sides from the position where the positive complementary color of the color of the sealing hole insertion portion 110 is located in the hue circle of the Munsell system (same hue). When viewed from the center of the ring, the color is located in the range from the position where the positive complementary color of the color of the sealing hole insertion portion 110 is located 90 ° counterclockwise to the position where it is advanced 90 ° clockwise. It is also included in the case. For example, when the color of the sealing hole insertion portion 110 is “5R” in the hue circle of the Munsell system, the color of the head 120 is “10Y” to “5BG” (correct complementary color) to “10PB” of the same hue circle. Within the range of 180 °, it is assumed that “the color of the head portion 120 and the color of the sealing hole insertion portion 110 have a complementary color relationship”. In the present specification, in the hue ring of the Munsell system, the angle from the position where the color of the sealing hole insertion portion 110 is located to the position where the color of the head 120 is located (the angle viewed from the center of the hue circle) The absolute value) may be referred to as “a deviation angle from the color of the sealing hole insertion part 110 to the color of the head 120”.

  The deviation angle from the color that is the complementary color of the sealing hole insertion portion 110 to the color of the head portion 120 is 54 ° or less (for example, when the color of the sealing hole insertion portion 110 is “5R” in the hue ring of the Munsell system). In particular, the color of the head 120 is preferably set to a color in the range of “10GY” to “5BG” (regular complementary color) to “10B” of the same hue ring). The deviation angle from the color that is the complementary color of the sealing hole insertion portion 110 to the color of the head portion 120 is 36 ° or less (for example, when the color of the sealing hole insertion portion 110 is “5R” in the hue ring of the Munsell system). It is more preferable to set the color of the head 120 to a color in the range of "5G" to "5BG" (regular complementary color) to "5B" of the same hue ring, and to be 18 ° or less (for example, inserting a sealing hole). When the color of the part 110 is “5R” in the hue circle of the Munsell system, the color of the head 120 is set to a color in the range of “10G” to “5BG” (correct complementary color) to “10BG” of the same hue circle. Yes) is more preferable.

(2) Concerning Form of Sealing Hole Inserting Portion If the sealing hole inserting portion 110 can be inserted into the sealing hole α and can engage with the engaged portion α ₃ in the inner portion of the sealing hole α, its form is particularly preferable. Not limited. In the gaming machine sealing member 100 of the first embodiment, as shown in FIG. 5, a sealing hole insertion portion 110 is provided with a substantially cylindrical main body portion 111 and a base end side of the main body portion 111 (y-axis in the same figure). The closing portion 112 is configured to close the negative side in the direction).

By forming the main body 111 of the sealing hole insertion portion 110 into a substantially cylindrical shape having a hollow portion without forming a solid structure, when the gaming machine sealing member 100 is fitted into the sealing hole α, A space in which the head of the screw (fixing tool 70 in FIG. 4) can be accommodated can be secured inside the main body 111, and compared with the case where the main body 111 has a solid structure, It is possible to secure the sealing hole insertion portion 110 for a long time. Further, it is possible to reduce the amount of material used for molding the gaming machine sealing member 100 and to reduce the manufacturing cost of the gaming machine sealing member 100. Further, in the gaming machine sealing member 100 of the first embodiment, as will be described later, the main body portion 111 of the sealing hole insertion portion 110 is engaged with the engaged portion α ₃ provided in the sealing hole α. Since the engaging portion 111c is provided, the engaging portion 111c can be easily elastically displaced when the game machine sealing member 100 is fitted into the sealing hole.

On the other hand, the closing portion 112 of the sealing hole insertion portion 110 is formed in a continuous surface shape having no opening or the like. This is to prevent unauthorized access from outside the sealing hole α to the sealing target portion α ₁ through the hollow portion of the main body 111. In the gaming machine sealing member 100 of the first embodiment, the head portion 120 of the gaming machine sealing member 100 has a central portion 121, and unauthorized access through the hollow portion of the main body portion 111 occurs in the central portion 121. The blocking part 112 is not an essential part because it can be prevented. However, in the gaming machine sealing member 100 of the first embodiment, as described above, both the sealing hole insertion portion 110 including the closing portion 112 and the head portion 120 including the central portion 121 are colored and transparent. When the sealing hole insertion part 110 and the head part 120 are made to have different colors, by arranging the closing part 112 on the back surface side (the positive side in the y-axis direction) of the central part 121, the breakage that occurs in the central part 121 or Marks such as whitening are easily noticed.

  The outer surface shape of the main body 111 of the sealing hole insertion portion 110 is appropriately determined according to the inner surface shape of the sealing hole α and the like. Examples of the outer surface shape of the main body portion 111 include a shape having only curved surfaces such as a cylinder and an elliptic cylinder, a shape having only flat surfaces such as a polygonal cylinder, and a shape having a mixture of curved surfaces and flat surfaces. It In the gaming machine sealing member 100 of the first embodiment, the outer surface shape of the main body portion 111 is a shape having a pair of flat surface portions 111a and a pair of curved surface portions 111b as shown in FIG. It corresponds to the inner shape of α. The outer peripheral surface near the tip of the main body portion 111 is formed in a tapered shape so that the sealing hole insertion portion 110 can be easily inserted into the sealing hole α.

  As shown in FIG. 5, the main body portion 111 of the sealing hole insertion portion 110 is provided with an engagement portion 111c, a stopper protrusion portion 111d, and an obstacle protrusion portion 111e.

The engagement portion 111c is provided on the outer peripheral portion of the sealing hole insertion portion 110. The engagement portion 111c is configured such that the sealing hole insertion portion 110 is inserted into the sealing hole α so that the sealing hole insertion portion 110 cannot be pulled out from the sealing hole α. It is a part for engaging with ₃ . The engaging portion 111c may be provided at a portion other than the tip portion of the main body portion 111, but is provided at the tip portion of the main body portion 111 in the gaming machine sealing member 100 of the first embodiment. Accordingly, the engaging portion 111c after the gaming machine sealing member 100 is fitted into the sealing hole α can be positioned on the inner side of the sealing hole α. Therefore, even if an illegal instrument such as a flat-blade screwdriver or a wire is inserted into the gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the gaming machine sealing member 100, the illegal instrument is hard to reach the engaging portion 111c, It is possible to make it difficult to illegally release the engagement of the engagement portion 111c.

  The engaging portion 111c may be provided at only one place in the main body 111, but is usually provided at a plurality of places in the main body 111. In this way, by providing the engaging portions 111c at a plurality of positions, an illegal instrument such as a flat-blade screwdriver or a wire is inserted into the gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the gaming machine sealing member 100, and the engagement is performed. When the engaging portion 111c is to be disengaged illegally, it is necessary to disengage the plurality of engaging portions 111c, and it can be troublesome to disengage the engaging portion 111c. Is.

  As described above, when the engaging portions 111c are provided at a plurality of locations on the body portion 111, the plurality of engaging portions 111c are symmetrical with respect to the center line of the body portion 111 (the center line parallel to the y-axis direction). It is preferable to provide it at a proper position. Thereby, the sealing member 100 for gaming machine fitted in the sealing hole α is not only stably engaged with the sealing hole α, but also when the sealing member 100 for gaming machine is fitted in the sealing hole α, It becomes possible to make the sealing member 100 difficult to tilt. Also in the gaming machine sealing member 100 of the first embodiment, as shown in FIG. 5B, two engaging portions 111c are provided in opposite positions at positions symmetrical with respect to the center line of the main body portion 111. ing.

  At this time, the engaging portion 111c may be provided on the flat surface portion 111a on the peripheral wall of the main body portion 111, but in the gaming machine sealing member 100 of the first embodiment, it is provided on the curved surface portion 111b on the peripheral wall of the main body portion 111. ing. As a result, it becomes possible to make it difficult to perform an illegal act using an illegal instrument having a plate-like tip portion like a minus driver. This is because an illegal insertion tool having a plate-shaped tip portion is difficult to insert into a curved gap.

The form of the engaging portion 111c is not particularly limited, and may be a concave portion that can be engaged with a convex portion (engaged portion) formed on the inner peripheral portion of the sealing hole α, but the gaming machine of the first embodiment. In the sealing member 100 for use, a convex portion protruding outward from the outer peripheral surface of the sealing hole insertion portion 110 is used as the engaging portion 111c. When the gaming machine sealing member 100 is fitted into the sealing hole α, this convex portion (engaging portion 111c) is in the fitting direction front side (y-axis direction negative side) of the convex portion (engaging portion 111c). The surface facing the is engaged with the engaged portion α ₃ provided in the sealing hole α (in the example of FIG. 4, the opening end surface on the back side (the positive side in the y-axis direction) of the peripheral wall portion surrounding the sealing hole α). It has become a thing.

As shown in FIG. 6, the outer surface of the convex portion (engagement portion 111c) (the surface facing the outside when viewed from the center line of the main body portion 111) extends from the tip end side (y axis direction positive side) to the base end side (y. It is formed in a state of being inclined so as to largely project outward toward the negative side in the axial direction. In addition, as shown in FIG. 5, slits are provided on both sides of the convex portion (engagement portion 111c), and the convex portion (engagement portion 111c) has only a strip-shaped portion and the main body portion 111. It is in the state of being connected with. Therefore, when the gaming machine sealing member 100 is fitted into the sealing hole α, the outer surface of the convex portion (engaging portion 111c) is smoothly brought into contact with the inner peripheral surface of the sealing hole α, and the convex portion (engaging The part 111c) is naturally displaced inside the main body part 111, and the convex part (engagement part 111c) is not caught on the inner peripheral part of the sealing hole α, so that the sealing member 100 for a gaming machine has a predetermined depth (convex part). The (engagement portion 111c) can be smoothly inserted up to a depth over which the engaged portion α ₃ can be overcome. When the gaming machine sealing member 100 is pushed to a predetermined depth, the convex portion (engaging portion 111c) elastically returns to the initial position, so that the convex portion (engaging portion 111c) engages with the engaged portion α ₃ . Are combined.

  By the way, in the gaming machine sealing member 100 of the first embodiment, as described above, when the sealing hole insertion portion 110 is provided with the closing portion 112, the front side of the closing portion 112 (the negative side in the y-axis direction). As shown in FIG. 5, the character string of "YAMASA" is engraved on the surface facing the. This makes it difficult to forge the game machine sealing member 100. Further, when the central portion 121 of the head portion 120 of the gaming machine sealing member 100 is broken or whitened at the time of unauthorized access, it becomes difficult to visually recognize the characters displayed in the closed portion 112. It becomes easier to notice that the central portion 121 is broken or whitened, as compared with the case where no characters are displayed in the closing portion 112. A figure, a symbol, or the like may be displayed in the closing unit 112 instead of a character.

  As a mode of engraving characters, figures, symbols or the like (hereinafter, may be referred to as “characters or the like”) on the closing portion 112, a mode in which a part of the character or the like is provided in a state of protruding from the surrounding portion ( A mode in which characters and the like are provided as convex portions, and a mode in which portions such as characters and the like are recessed from the periphery thereof (a mode in which characters and the like are provided as concave portions) are included. Any of these may be adopted, but as described above, when the sealing hole insertion portion 110 and the head 120 in the gaming machine sealing member 100 are two-color molded, a synthetic resin system for molding the head 120. In consideration of the flow of the synthetic resin material at the time of injecting the material, it may be preferable to provide the character or the like as a recess.

As shown in FIG. 5, the stopper protrusion 111d is provided at a position spaced a predetermined distance from the end of the outer periphery of the sealing hole insertion portion 110 where the flange 122 is provided (on the positive side in the y-axis direction). It is provided so as to project outward. When the gaming machine sealing member 100 is fitted into the sealing hole α, the stopper projection 111d comes into contact with the counterbore surface α ₂ (FIG. 4) of the sealing hole α, and the gaming machine sealing member 100 seals. It is a portion that functions as a stopper for preventing further movement to the inner part of the hole α. Therefore, the stopper projection 111d is formed to be strong so as to withstand the pressing force received from the spot facing surface α ₂ .

  The stopper protrusion 111d may be formed continuously over the entire outer peripheral portion of the sealing hole insertion portion 110, but in this case, the portion for injection-molding the stopper protrusion 111d has a wide annular shape. Since it is formed, there is a possibility that trouble may easily occur during injection molding of the gaming machine sealing member 100. Therefore, in the game machine sealing member 100 of the first embodiment, the stopper projections 111d are a total of one at each of the pair of flat surface portions 111a and two at each of the pair of curved surface portions 111b in the sealing hole insertion portion 110. It is divided into six places.

  As shown in FIG. 5, the baffle protrusion 111e is located on the distal end side (the positive side in the y-axis direction) of the stopper protrusion 111d on the outer peripheral portion of the sealing hole insertion portion 110 and on the base end of the engagement portion 111c. It is provided so as to project outward from the position on the side (the negative side in the y-axis direction). In the game machine sealing member 100 of the first embodiment, as described above, the stopper projections 111d are provided at a plurality of divided portions, and the stopper projections are provided on the outer peripheral portion of the sealing hole insertion portion 110. Although there is a section in which the portion 111d does not exist, the hindrance projection 111e is a section in which the stopper projection 111d does not exist, and the gaming machine sealing member 100 is viewed from the center line direction (y-axis direction). It is provided at a position that overlaps with the engaging portion 111c when viewed. In the gaming machine sealing member 100 of the first embodiment, the two engaging portions 111c are provided in opposite directions at positions symmetrical to each other when viewed from the center line of the main body portion 111, so that the two obstructing protrusion portions 111e are provided. , Are provided in opposite directions at positions symmetrical with respect to the center line of the main body 111.

Thereby, a person who attempts to illicitly release the engaging portion 111c has a section (stopper protrusion 111d) overlapping the engaging portion 111c in the gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the sealing hole inserting portion 110. Even if an illegal instrument such as a flat-blade screwdriver is inserted well from the space where the illegal instrument is not provided, the illegal instrument reaches the place where the engaging portion 111c is provided because the illegal instrument is obstructed by the disturbing protrusion 111e. It becomes possible not to do it. In the gaming machine sealing member 100 according to the first embodiment, each of the obstacle protrusions 111e is inserted between the pair of protrusions α ₄ (FIG. 4) provided on the inner peripheral portion of the sealing hole α. Therefore, it is difficult to release the engaging portion 111c from the front side of the sealing hole α unless the convex strip α ₄ and the baffle protrusion 111e are destroyed.

(3) Form of Head As described above, the head 120 is composed of the flange portion 122 and the central portion 121. The flange portion 122 is formed in a shape capable of closing the front side of the counterbore surface α ₂ in the sealing hole α. Therefore, the flange portion 122 is usually formed continuously over the entire peripheral portion of the base end outer peripheral portion of the sealing hole insertion portion 110. On the other hand, the central portion 121 is formed so as to close the inner area of the flange portion 122. The protrusion length L ₁ (FIG. 6) of the flange portion 122 is not particularly limited, but if it is too short, the flange portion 122 covers the gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the sealing hole insertion portion 110. There is a risk that it will not be possible. Further, the flange 122 may be less likely to break or whiten when an illegal instrument such as a flat-blade screwdriver is inserted into the gap. Therefore, the protrusion length L ₁ of the flange portion 122 is usually 1 mm or more. The protrusion length L ₁ of the flange portion 122 is preferably 1.5 mm or more, and more preferably 2 mm or more. The protrusion length L ₁ of the flange portion 122 has no particular upper limit, but is usually up to about 10 mm. The flange portion 122 is generally formed to be weaker than the stopper projection portion 111d.

2.2 Sealing member for gaming machine according to second embodiment Next, the sealing member 100 for gaming machine according to the second embodiment will be described. With regard to the gaming machine sealing member 100 of the second embodiment, mainly the portions different from the gaming machine sealing member 100 of the first embodiment will be described. The structure of the sealing member 100 for gaming machine according to the second embodiment, which is not particularly mentioned, is substantially the same as that described in the sealing member 100 for gaming machine according to the first embodiment, and thus the description thereof is omitted.

  FIG. 8 is a perspective view of the gaming machine sealing member 100 according to the second embodiment, showing a state (a) viewed from the front upper right and a state (b) viewed from the rear upper right, respectively. FIG. 9 is a perspective view showing a state in which the sealing hole insertion portion 110 in the gaming machine sealing member 100 of the second embodiment is viewed from the front upper right. In FIG. 8 and FIG. 9, only the sealing hole insertion portion 110 is shown by hatching in order to make it easier to distinguish the sealing hole insertion portion 110 and the head portion 120 in the gaming machine sealing member 100 in the drawings. FIG. 10 is a cross-sectional view showing a state in which the gaming machine sealing member 100 of the second embodiment is cut along a plane that includes the center line of the gaming machine sealing member 100 and is parallel to the yz plane.

In the game machine sealing member 100 of the above-described first embodiment, as shown in FIG. 5, in the sealing hole inserting portion 110, the base end outer peripheral portion in contact with the head 120 (the base end outer peripheral portion of the sealing hole inserting portion 110). The shape of () was substantially the same as the outer peripheral shape of the section of the sealing hole insertion portion 110 other than the base end. On the other hand, in the gaming machine sealing member 100 of the second embodiment, as shown in FIGS. 8 and 9, a plurality of protrusions having outward edges 110a ₁ are formed on the outer peripheral portion of the base end of the sealing hole insertion portion 110. The part 110a is repeatedly provided. In the gaming machine sealing member 100 of the second embodiment, as shown in FIG. 10, a plurality of convex portions are embedded in the head 120, and a surface of the plurality of convex portions 110a facing the inner side ( The surface facing the positive side in the y-axis direction) is substantially flush with the surface facing the rear side in the flange portion 122 (the surface facing the positive side in the y-axis direction).

As a result, if an unauthorized device is inserted into the gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the gaming machine sealing member 100, and the unauthorized access to the sealing target location α ₁ is attempted, the flange portion 122, and the stress on the portion abutting against the edge 110a ₁ of the convex portion 110a is likely to concentrate, the flange portion 122, cracks originating from the portion abutting against the edge 110a ₁ of the convex portion 110a (FIG. 7 Can be easily generated. In this case, the sealing hole insertion portion 110 located on the back side is easily visible in a color different from that of the head portion 120 from the portion where the crack or the like occurs in the flange portion 122 (the crack β or the like). Therefore, when an unauthorized access is attempted, it is possible to easily form a mark in a more difficult-to-delete and more conspicuous manner on the head 120 including the flange 122.

The plurality of convex portions 110a may be provided only in a partial section in the circumferential direction of the base end outer peripheral portion of the sealing hole inserting section 110 (particularly, a section overlapping the front side of the engaging section 111c), but the sealing hole inserting section It is preferable to provide it on the entire circumference in the circumferential direction of the base end outer circumference of the portion 110. As a result, no matter where the illicit instrument is inserted into the gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the sealing hole insertion portion 110, the illicit device abuts on the edge 110a ₁ of the convex portion 110a. It becomes possible to easily form a crack or the like having the portion as a starting point in the flange portion 122. The number of the convex portions 110a varies depending on the size of the sealing hole insertion portion 110 and the like and is not particularly limited, but is usually about 3 to 50, preferably about 5 to 40.

The shape of each of the protrusions 110a when viewed from the fitting direction (y-axis direction) of the gaming machine sealing member 100 (the shape of the protrusion 110a in plan view) is particularly limited as long as it has an outward edge 110a _1. However, it is usually triangular. The angle of the edge 110a ₁ (angle when the convex 110a is viewed from the negative side in the y-axis direction) is not particularly limited. For cracks originating from the portion abutting against the edge 110a ₁ of the convex portion 110a is easily formed by the flange portion 122, when the angle of the edge 110a ₁ of the convex portion 110a small to be sharpened protrusions 110a preferable. Specifically, the angle of the edge 110a ₁ of the convex portion 110a is preferably 150 ° or less, more preferably 120 ° or less, and further preferably 90 ° or less (acute angle). However, if the angle of the edge 110a ₁ of the convex portion 110a is too small, the strength of the convex portion 110a may decrease and the convex portion 110a may be easily damaged. Therefore, the angle of the edge 110a ₁ of the convex portion 110a is preferably 30 ° or more.

The protrusion length L ₂ (FIG. 10) of each protrusion 110 a is not particularly limited as long as it is shorter than the protrusion length L ₁ (FIG. 10) of the flange 122. However, if the protrusion length L ₂ of the convex portion 110a is too short, the dimension of the convex portion 110a inevitably becomes small, and the convex portion 110a is formed over the entire circumference of the base end outer peripheral portion of the sealing hole insertion portion 110. In order to provide it, it becomes necessary to form a large number of minute convex portions 110a. Therefore, it is difficult to form the sealing hole insertion portion 110, and it may be difficult to sharply form the edge 110a ₁ of the convex portion 110a. Therefore, the protrusion length L ₂ of the protrusion 110a is usually set to 0.3 mm or more. The protrusion length L ₂ of the convex portion 110a is preferably 0.5 mm or more, and more preferably 0.7 mm or more. On the other hand, if the protrusion length L ₂ of the convex portion 110a is too close to the protrusion length L ₁ of the flange portion 122, an unauthorized instrument is inserted into the gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the flange portion 122. When this is done, there is a risk that traces such as breakage or whitening will be less likely to occur on the flange 122. Therefore, the ratio L ₂ / L ₁ of the protrusion length L ₂ of the convex portion 110a to the protrusion length L ₁ of the flange portion 122 is preferably 0.7 or less. The ratio L ₂ / L ₁ is more preferably 0.6 or less, and further preferably 0.5 or less.

2.3 Game Machine Sealing Member of Third Embodiment Next, the game machine sealing member 100 of the third embodiment will be described. With regard to the gaming machine sealing member 100 of the third embodiment, mainly the parts different from the gaming machine sealing member 100 of the second embodiment will be described.

It was provided at two locations, the surface (the surface facing the y-axis direction negative side) side and the back surface (the surface facing the y-axis direction positive side). Therefore, in the gaming machine sealing member 100 of the second embodiment, not only when an unauthorized device is inserted into the gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the gaming machine sealing member 100, but also the sealing hole. Due to the pressing force applied to the head portion 120 such as the flange portion 122 when the gaming machine sealing member 100 is normally fitted to α, cracks or the like originating from the edge 110a ₁ on the front surface side of the convex portion 110a are generated. There is a possibility that it may occur on the head such as the flange 122. That is, the sealing hole insertion portion 110 located on the back side is the head from the gap (such as the crack β) generated in the flange portion 122 when the gaming machine sealing member 100 is normally fitted into the sealing hole α. The color is different from that of the section 120, and there is a possibility that the unauthorized access is made even though the unauthorized access is not made.

On the other hand, in the gaming machine sealing member 100 of the third embodiment, as shown in FIGS. 12 and 13, the front surface of the convex portion 110a is formed smoothly, and only the back surface side of the convex portion 110a is formed. The edge 110a ₁ is formed. Therefore, when the gaming machine sealing member 100 is properly fitted into the sealing hole α, the flange 122 is prevented from cracking or the like, and unauthorized access is made even though unauthorized access is not made. While not being erroneously recognized as being accessed, a fraudulent instrument is inserted into the gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the gaming machine sealing member 100, and thus the illegality to the sealing target location α ₁ When an access is attempted, it is possible to easily cause a trace such as a crack (a crack β or the like) on the flange portion 122.

With regard to the gaming machine sealing member 100 of the fourth embodiment, mainly the portions different from the gaming machine sealing member 100 of the third embodiment will be described. The configuration of the sealing member 100 for gaming machine according to the fourth embodiment that is not particularly referred to is substantially the same as that described for the sealing member 100 for gaming machine according to the third embodiment, and thus the description thereof is omitted.

  FIG. 14 is a perspective view of the gaming machine sealing member 100 of the fourth embodiment, showing a state (a) viewed obliquely from the front upper right and a state (b) viewed obliquely upper right from the rear. FIG. 15 is a perspective view showing a state in which the sealing hole insertion portion 110 in the gaming machine sealing member 100 of the fourth embodiment is seen from the front upper right. FIG. 16 is a cross-sectional view showing a state in which the gaming machine sealing member 100 of the fourth embodiment is cut along a plane that includes the center line of the gaming machine sealing member 100 and is parallel to the yz plane. FIG. 17 is a diagram of the gaming machine sealing member 100 according to the fourth embodiment as viewed from the front side (the negative side in the y-axis direction), in which (a) a state in which a tear β is not formed in the head 120, and ( FIG. 7B is a diagram showing a state in which a split β is generated in the head 120. 14, FIG. 15 and FIG. 17, only the sealing hole insertion portion 110 is shown by hatching in order to make it easier to distinguish the sealing hole insertion portion 110 and the head portion 120 in the gaming machine sealing member 100 in the drawings. ing.

  In the game machine sealing member 100 of the third embodiment described above, as shown in FIG. 11A, the entire head end 120 on the base end (the end on the negative side in the y-axis direction) of the sealing hole insertion portion 110 is the head 120. Thus, the sealing hole insertion portion 110 was not exposed on the front surface (the surface on the negative side in the y-axis direction) of the head 120. On the other hand, in the gaming machine sealing member 100 of the fourth embodiment, as shown in FIGS. 14 (a), 16 and 17, an opening 121a for exposure is provided in the central portion 121 of the head 120. The sealing hole insertion portion 110 located on the back side of the head 120 is exposed to the front surface (the surface facing the negative side in the y-axis direction) of the head 120 through the exposure opening 121a. Therefore, it is possible to easily grasp whether or not a crack β, a chip, or the like caused by the unauthorized access is generated in the head portion 120 such as the flange portion 122.

  That is, in the gaming machine sealing member 100 of the first embodiment in which the entire surface on the base end side (negative side in the y-axis direction) of the sealing hole insertion portion 110 is covered with the head 120, FIG. As shown in the figure, the sealing hole insertion portion 110 (usually, the closing portion 112 of the sealing hole insertion portion 110) on the back side is different from the head portion 120 due to the rupture β, the chipping, and the like generated in the head portion 120 during the unauthorized access. Even if the color is different, it is not possible to judge whether the color is the color of the sealing hole insertion portion 110 or the color of other members arranged around the sealing hole insertion portion 110, and the inspector cannot judge. There is a possibility that the judgment regarding the presence or absence of unauthorized access may be wrong. On the other hand, like the gaming machine sealing member 100 according to the fourth embodiment, the head 120 is provided with the exposure opening 121a for exposing the sealing hole insertion portion 110. ), The color of the worrisome portion (the portion that is suspected to have a crack β or a chip due to unauthorized access) is the same as the color of the sealing hole insertion portion 110 visible through the exposure opening 121a. By contrast, it is possible to easily determine whether or not the color that is visible in the concerned portion is the color of the sealing hole insertion portion 110, and it is possible to accurately determine the presence or absence of unauthorized access. become.

  A portion of the sealing hole insertion portion 110 exposed from the exposure opening 121a (usually a portion of the closing portion 112 of the sealing hole insertion portion 110. Hereinafter, this portion may be referred to as a “reference portion”).

The exposed convex portion 112a is formed so as to be convex on the negative side in the y-axis direction, and the surface on the front side (negative side in the y-axis direction) of the exposed convex portion 112a is substantially flush with the front surface of the head 120. ing. Therefore, it is possible to position the reference portion on the front side and prevent the shadow of the opening edge of the exposure opening 121a from being formed in the reference portion. Therefore, it becomes easy for the inspector to visually recognize the reference portion, and it is possible to grasp the original color of the reference portion (sealing hole insertion portion 110) and more accurately and easily determine the presence or absence of unauthorized access. ing.

  Further, when the portion exposed from the exposure opening 121a in the closing portion 112 (sealing hole insertion portion 110) is the exposed convex portion 112a that is convex toward the front side, when the gaming machine sealing member 100 is normally fitted. It is also possible to prevent plastic deformation such as whitening or breakage of the head 120. This is because the head portion 120 is a portion formed of a synthetic resin material having low strength and brittleness, and is a portion that is pressed by a finger or the like when the sealing member for gaming machine is fitted into the sealing hole. Therefore, when the game machine sealing member 100 is properly fitted into the sealing hole α, the head portion 120 may be whitened or broken, and the closed portion 112 (sealing hole By making the exposed portion 112a of the insertion portion 110) exposed from the exposure opening 121a convex toward the front side, a finger or the like can be used to fit the gaming machine sealing member 100 into the sealing hole α. This is because the applied load can be directly received by the sealing hole insertion portion 110 having high strength.

  By the way, in the gaming machine sealing member 100 of the fourth embodiment, as shown in FIG. 14A, a rib 122a protruding toward the front surface side is provided at the outer edge portion of the front surface of the flange portion 122. Accordingly, when an unauthorized instrument is inserted into the gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the flange portion 122, the unauthorized instrument is farther away from the root portion of the flange portion 122 in the flange portion 122. Will come into contact with the ribs. Therefore, when an unauthorized instrument is inserted into the gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the flange portion 122, a large force is easily applied to the root portion of the flange portion 122, and the attachment of the flange portion 122 is facilitated. Traces such as breakage and whitening can be more easily left on the root.

The ribs 122a may be provided along the entire circumference of the outer edge of the flange portion 122 on the front surface side. However, the protrusion length L ₁ (FIG. 16) of the flange portion 122 is short, and the rib 122a extends from the root portion of the flange portion 122. It may be provided only at a location where the distance to the outer end cannot be secured. In the gaming machine sealing member 100 of the fourth embodiment, as shown in FIG. 14 (a), the rib 122a is provided only at a location along the outer edge portion on the left side of the flange portion 122. The left side portion of the flange portion 122 has a shorter protrusion length L ₁ of the flange portion 122 than the other portions (upper side portion, lower side portion and right side portion) of the flange portion 122.

  As described above, the gaming machine sealing member 100 of the fourth embodiment makes it easier to find a trace of unauthorized access, as compared with the gaming machine sealing member 100 of the first embodiment to the third embodiment. , It becomes easier to prevent fraudulent acts against gaming machines.
