Description

  The present invention relates to a game machine sealing member for sealing a sealing target portion located at the back of a sealing hole by being fitted into a sealing hole provided in a game machine, and a game for manufacturing the gaming machine sealing member. The present invention relates to a method of manufacturing a machine sealing member and a sealing structure of a gaming machine for sealing a sealing target portion using the gaming machine sealing member.

  A gaming machine can be subject to various fraudulent acts. For example, various substrate units are accommodated inside the housing of the gaming machine, and a storage device (usually a ROM) on which a program for controlling the gaming machine is recorded is mounted on these substrate 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 cheating, each maker of the gaming machine has a structure in which a device such as a substrate unit or the like to be cheating is housed in a case (substrate case), and the substrate case is closed. The location that was screwed etc. (location to be sealed) is sealed with a sealing member to make unauthorized access to the location to be sealed difficult to prevent, and in the case where unauthorized access is made to the location to be sealed by any chance, Measures are taken to ensure that traces remain on the sealing member.

  As described above, various kinds of sealing members for gaming machines have been proposed as sealing members for gaming machines used for sealing a substrate case or the like of gaming machines. For example, as shown in FIG. 2 of Patent Document 1, the applicant of the present application has made a cylindrical insertion in which a portion to be sealed (a portion to be sealed) is inserted into a sealing hole (sealing hole) provided at the back. Section 11 (sealing hole insertion portion) and a lid 12 (head having a flange portion) disposed on the base end side of the sealing hole insertion portion 11 for covering the sealing hole via the connection portion 13 The sealing member 1 (sealing member) of the structure which connected the base end of the sealing hole insertion part 11 only in one part area (alpha) in the circumferential direction is proposed. At the outer peripheral portion of the sealing hole insertion portion 11, an engaging portion 111 for engaging with the inner peripheral portion of the sealing hole is provided.

  In the sealing member 1 of Patent Document 1, as shown in FIG. 4 of the same document, a illegitimate insertion tool T (illegal device) is inserted into the gap S between the inner peripheral surface of the sealing hole 21 and the outer peripheral surface of the sealing member 1 When trying to release the engagement of the engaging portion 111 by pushing the engaging portion 111 inward with the tip of the incorrect device T, the connecting portion 13 is broken by the force applied to the flange portion 12 from the incorrect device T. Is assumed. As described above, when unauthorized access is made to the sealing target location A sealed by the sealing member 1 of Patent Document 1, since a trace remains in the connecting portion 13 or the like of the sealing member 1, unauthorized access is made by checking the presence or absence of the trace. It is possible to confirm the presence or absence of

Patent No. 5447901 gazette

  However, in the sealing member 1 of Patent Document 1, since the connecting portion 13 intended to leave a trace of unauthorized access is provided locally in a narrow range, the range in which the trace of unauthorized access is formed is also around the connecting portion 13 It is easy to stay in a narrow range. In addition, the connecting portion 13 is provided at a relatively invisible position on the back side of the flange portion 12. Therefore, even if the connecting member 13 is broken or the like at the time of unauthorized access, the sealing member 1 of Patent Document 1 becomes difficult to notice the trace when the broken portion is adhered with an adhesive or the like. There was a fear.

  The present invention has been made to solve the above-mentioned problems, and a trace of unauthorized access is formed in a wide range, it is difficult to erase the trace, and the trace can be detected more reliably. By doing this, it is possible to provide a gaming machine sealing member capable of preventing a fraudulent act on a gaming machine. Another object of the present invention is to provide a method of manufacturing a sealing member for gaming machine for manufacturing the sealing member for gaming machine. Furthermore, it is also an object of the present invention to provide a sealing structure of a gaming machine for sealing a portion to be sealed using the gaming machine sealing member.

The above task is
In a gaming machine sealing member for sealing a sealing target location located at the back of a sealing hole by fitting into a sealing hole provided in a gaming machine,
A sealing hole inserting portion made of a synthetic resin material, which is a portion to be inserted into the sealing hole and has an engaging portion on an outer peripheral portion for engaging with an engaged portion provided in the sealing hole;
A flange portion made of a synthetic resin material and provided on the base end side of the sealing hole insertion portion, which is a portion for covering a gap between the outer peripheral surface of the sealing hole insertion portion and the inner peripheral surface of the sealing hole;
Equipped with
It is solved by providing a sealing member for a gaming machine characterized in that the flange portion is formed of a synthetic resin material having a strength lower than that of the sealing hole inserting portion.

  Here, "strength" in "the flange portion is formed of a synthetic resin material having a strength lower than that of the sealing hole inserting portion" means "Izod impact strength". Examples of synthetic resin materials that form the flange portion and the sealing hole insertion portion include methyl methacrylate resin (PMMA), polypropylene (PP), polystyrene (PS), acrylonitrile-butadiene-styrene copolymer synthetic resin (ABS) And thermoplastic resins such as polycarbonate (PC). These synthetic resin materials are listed in Table 1 below in the order of low Izod impact strength. However, Izod impact strength in Table 1 below is a general value until it gets tired, and the value in each thermoplastic resin increases or decreases depending on the specific specification of the thermoplastic resin, etc., and the order of each thermoplastic resin changes. Sometimes. Among these synthetic resin materials, the Izod impact strength is relatively high to form a sealing hole insertion portion, and the flange portion is formed from a resin having an Izod impact strength lower than that of the resin forming the sealing hole insertion portion.

  By forming the flange portion with a synthetic resin material having a strength lower than that of the sealing hole insertion portion as in this configuration, the unauthorized device is formed in the gap between the inner peripheral surface of the sealing hole and the outer peripheral surface of the game machine sealing member. When an unauthorized access to the sealing target portion is attempted by inserting or the like, a trace such as breakage or whitening is formed in a wide range in the flange portion. In particular, stress tends to be concentrated in the vicinity of the portion in contact with the sealing hole insertion portion having relatively high strength and relatively low strength and brittle flange portion, and cracks etc. are generated starting from the vicinity of the portion where the stress is concentrated It can be made easy. 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, even when the gaming machine sealing member is fitted in the sealing hole, a trace of unauthorized access remains in the easily visible flange portion, making it easy to find a trace of unauthorized access.

  In the gaming machine sealing member according to the present invention, the edge facing outward on the portion (hereinafter referred to as "proximal peripheral portion of the sealing hole inserting portion") in contact with the flange portion in the outer peripheral portion of the sealing hole inserting portion. It is also preferable to repeatedly provide a plurality of convex portions having.

  For example, as described above, when the flange portion is formed of a synthetic resin material having a strength lower than that of the sealing hole insertion portion, the sealing hole insertion portion (relatively low strength and brittle portion) (relatively strong and fragile) A crack or the like originating from the vicinity of the portion where high strength is in contact is likely to be formed. With this 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 game machine sealing member. When unauthorized access to the sealing target portion is attempted, stress is more likely to be concentrated on the portion of the flange portion that abuts on the outward edge, and the outward It is possible to further easily generate a crack or the like starting from a portion in contact with the edge of the. Therefore, when unauthorized access is attempted, it is possible to leave a trace of a more difficult to erase and more conspicuous aspect on the flange portion.

In the gaming machine sealing member of the present invention, in the case where a plurality of convex portions having outward edges are provided on the proximal end outer peripheral portion of the sealing hole insertion portion,
The plurality of convex portions are embedded in the lower surface of the flange portion (the surface connected to the sealing hole insertion portion) side, and
Forming smoothly the front surface side (surface opposite to the surface connected to the sealing hole inserting portion) of each of the convex portions,
It is preferable to provide the outward edge on the rear surface side of each of the convex portions.

  For example, when an edge is formed on the front surface side of the plurality of convex portions, a press applied to the flange when the game machine sealing member is fitted into the sealing hole (when properly fitted) Also by the pressure, there is a possibility that traces such as breakage or whitening may easily occur on the flange portion. In this respect, as in the above configuration, the outward facing edge is not provided on the front surface side of the plurality of convex portions, but is provided on the rear surface side of the plurality of convex portions to play against the sealing hole. When inserting the machine sealing member properly, the clearance between the inner peripheral surface of the sealing hole and the outer peripheral surface of the game machine sealing member is incorrect while making sure that no trace such as breakage or whitening occurs in the flange portion. This is because when an unauthorized access to the sealing target portion is attempted by inserting an instrument or the like, it is possible to easily cause a trace such as breakage or whitening to occur in the flange portion.

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

  By adopting such a configuration, when the 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, the unauthorized device is included in the sealing hole insertion portion of the flange portion. It comes into contact with a rib farther away from a portion in contact with the proximal end outer peripheral portion (which may be hereinafter referred to as "the root portion of the flange portion"). For this reason, 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 greater force is more likely to be applied to the base of the flange, and the base of the flange It is possible to make it easier to leave traces such as breakage and whitening.

  Although the manufacturing method of the sealing member for gaming machines of the present invention is not particularly limited, it is preferable that the sealing member be manufactured by two-color molding of the sealing hole inserting portion and the flange portion.

  For example, when a sealing member for a game machine is manufactured by bonding a sealing hole insertion portion and a flange portion which are separately molded with an adhesive or the like later, for example, impurities are adhered to the bonding portion. Not only the appearance of the sealing member for gaming machine may deteriorate, but also the impurities and the unevenness of the coating may be mistaken as a trace of unauthorized access. . In addition, there is a possibility that the flange portion may be broken when bonding the flange portion to the sealing hole insertion portion. In this respect, like this configuration, the sealing hole insertion portion and the flange portion can be finely integrated without damaging the flange portion by forming the sealing hole insertion portion and the flange portion in two colors. It is because it becomes possible.

It is also good. Further, the place where the sealing hole α is to be provided is not necessary to be a portion through which the fixing tool is inserted, and it is not necessary to be the substrate case 50 as long as it is a portion that needs sealing.

2. The sealing member for gaming machines of the present invention The sealing member 100 for gaming machines of the present invention will be described in more detail. Hereinafter, the gaming machine sealing member 100 according to the present invention will be described by taking four embodiments from the first embodiment to the fourth embodiment as an example. 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 modified without departing from the scope of the invention.

2.1 Game Machine Sealing Member of First Embodiment First, the game machine sealing member 100 of the first embodiment will be described. FIG. 4 is a perspective view showing the state where the gaming machine sealing member 100 of the first embodiment is fitted into the sealing hole α. FIG. 5 is a perspective view showing the state of the gaming machine sealing member 100 of the first embodiment as seen from (a) front diagonally upper right and (b) rear diagonally upper right. 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 (center line parallel to the y-axis direction) of the gaming machine sealing member 100. It is sectional drawing which showed. FIG. 7 is a view of the gaming machine sealing member 100 according to the first embodiment as viewed from the front side (the negative side in the y-axis direction), in the state where (a) no tears β occur in the head 120; b) It is the figure which showed the state which the crevice (beta) has produced in the head 120, respectively. In FIGS. 4, 5 and 7, only the sealing hole insertion portion 110 is shown by hatching in order to make it easy to distinguish between the sealing hole insertion portion 110 and the head portion 120 in the gaming machine sealing member 100. ing.

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

The gaming machine sealing member 100 of the first embodiment is configured of a sealing hole insertion portion 110 and a head 120. Each of the sealing hole insertion portion 110 and the head portion 120 is formed of a synthetic resin material. The sealing hole insertion portion 110 is a portion inserted from the tip (the end on the positive side in the y-axis direction in FIG. 4) side of the sealing hole α. An engagement portion 111 c is provided on the outer peripheral portion of the sealing hole insertion portion 110. When fitting the gaming machine seal member 100 to seal the holes alpha, the engaging portion 111c is engaged with the engaged portion alpha ₃ in the inner portion of the sealing hole alpha, the gaming machine seal member 100 It will be in the state which can not be pulled out to the near side. On the other hand, the head portion 120 is a portion provided on the base end side (the end portion on the negative side in the y-axis direction in FIG. 4) of the sealing hole insertion portion 110. In the sealing hole insertion portion 110 of the first embodiment, the head portion 120 is from the central portion 121 overlapping the base end surface (the closing portion 112 described later) of the sealing hole insertion portion 110 and the outer periphery of the proximal end of the sealing hole insertion portion 110 It comprises with the flange part 122 which protruded and was provided outward.

In a state where the gaming machine sealing member 100 is inserted into the sealing hole α, when attempting to gain unauthorized access to the sealing target portion α ₁ , the outer peripheral surface of the sealing hole insertion portion 110 and the sealing hole α from the outer peripheral portion of the flange portion 122 It is necessary to insert an unauthorized tool such as a flathead screwdriver into the gap with the inner circumferential surface and unfairly release the engagement of the engagement portion 111c or to make a hole in the gaming 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 is placed from the front side of the sealing hole α so that the unauthorized device 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. When it is covered and an unauthorized device is inserted into the gap, as shown in FIG. 7 (b), it becomes a part for leaving a trace such as chipping, breakage mark, whitening, etc. in addition to tears β. ing. In addition, when a hole or the like is opened in a portion other than the flange portion 122 in the gaming machine sealing member 100 (the central portion of the gaming machine sealing member 100), the central portion 121 shows the trace (fracture mark, whitening, etc.) It is a part to leave it.

That is, sealing the hole insertion part 110 is mainly as a game machine for sealing member 100 from the seal hole alpha is not pulled, the engaged portion alpha ₃ with the gaming machine seal member 100 to the inner part of the sealing hole alpha whereas it has a function to engage against the head 120 has primarily the function of expressing the traces of unauthorized access to seal target portion alpha _1. For this reason, the head 120 is formed of a material (synthetic resin material) whose strength (Izod impact strength) is lower than that of the sealing hole insertion portion 110. The synthetic resin-based material forming the head 120 and the sealing hole insertion portion 110 is not particularly limited as long as it has the above-described relationship in strength, but is formed of a transparent (including colored and transparent) synthetic resin-based material It is preferable then. Thereby, even in the state where the gaming machine sealing member 100 is fitted into the sealing hole α, it is visually observed whether or not there is an abnormality in the sealing object portion α ₁ at the back of the sealing hole α from the front side of the sealing hole α. It becomes possible to confirm.

  In this respect, as the synthetic resin-based material having transparency, 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. For this reason, the strengths of PMMA, PP, PS, ABS and PC are in the order as shown in Table 1, and the synthetic resin material forming the sealing hole insertion portion 110 and the head 120 is selected from Table 1. For example, it is as shown below. That is, when the sealing hole insertion part 110 is formed by PC, the head 120 is formed by PMMA, PP, PS or ABS. When the sealing hole insertion portion 110 is formed of ABS, the head 120 is formed of PMMA, PP or PS. Furthermore, when the sealing hole insertion part 110 is formed by PS, the head 120 is formed by PMMA or PP. Furthermore, when the sealing hole insertion part 110 is formed by PP, the head 120 is formed by PMMA.

  However, as described later, when the sealing hole insertion portion 110 and the head portion 120 in the game machine sealing member 100 are formed in two colors, the synthetic resin material forming the sealing hole insertion portion 110 and the head portion 120 is used. Also 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 having a high melting point and made of a synthetic resin material is first molded, and then a synthetic resin having a low melting point is used. This is because it is necessary to mold the side member formed of the base material later. In this respect, in general, the higher the melting point, the higher the strength (Izod impact strength) of the thermoplastic resin, and the magnitude relationship between the melting points of the respective thermoplastic resins and the magnitude relationship between the strengths of the respective thermoplastic resins Generally agree.

  The sealing hole insertion portion 110 and the head 120 in the gaming machine sealing member 100 are provided in an integrated manner. The method for integrating the sealing hole insertion portion 110 and the head portion 120 is not particularly limited. For example, the sealing hole insertion portion 110 and the head portion 120 which are separately formed are integrally bonded by an adhesive or the like later. You may make it However, the work of bonding the sealing hole insertion portion 110 and the head portion 120 is usually formed separately because the parts (the sealing hole insertion portion 110 and the head portion 120) are taken out one by one and manually operated. In the method of bonding the sealing hole insertion portion 110 and the head portion 120, there is a possibility that an impurity or the like may enter the bonding portion between the sealing hole insertion portion 110 and the head portion 120 or that coating unevenness may occur in the adhesive. . For this reason, not only the appearance of the sealing member 100 for a game machine is deteriorated, but there is also a possibility that its impurities, coating unevenness and the like may be mistaken as a trace of unauthorized access. In particular, in the game machine sealing member 100 of the present embodiment, as described later, a configuration in which the sealing hole insertion portion 110 and the head portion 120 are different colors is adopted. Although the color is also important, as described above, if impurities are mixed in the bonding portion between the sealing hole insertion portion 110 and the head portion 120, the color of the sealing hole insertion portion 110 or the head portion 120 may be adversely affected. . In addition, when the sealing hole insertion portion 110 and the head portion 120 are bonded, there is a possibility that the head portion 120 (in particular, the flange portion 122) may be damaged.

  For this reason, it is preferable that the sealing hole insertion portion 110 and the head portion 120 be integrated with each other by two-color molding. This allows the sealing hole insertion portion 110 and the head 120 to be integrated without using an adhesive and without manual operation. Therefore, it is possible to prevent the mixing of impurities at the boundary between the sealing hole insertion portion 110 and the head 120 and the coating unevenness of the adhesive at the boundary. Therefore, the sealing hole insertion portion 110 and the head portion 120 are not only made to show the original color of the sealing hole insertion portion 110 or the head portion 120 but also without damaging the head portion 120 (flange portion 122). It will also be possible to integrate beautifully. Also in the gaming machine sealing member 100 of the first embodiment, the sealing hole insertion portion 110 and the head 120 are integrated with each other by two-color molding. Specifically, after PC or ABS is injected into the first mold to form the sealing hole insertion part 110, a part of the first mold (a part to be connected to the proximal end of the sealing hole insertion part 110) For gaming machines in which the sealing hole insertion portion 110 and the head 120 are integrated by switching only the second mold to the second mold and injecting PMMA into the second mold to form the head 120. The sealing member 100 is obtained.

As described above, the head portion 120 including the flange portion 122 is formed of a synthetic resin material having a strength lower than that of the sealing hole inserting portion 110, so that the inner peripheral surface of the sealing hole α and the gaming machine sealing member 100. and such unauthorized appliances in the gap between the outer peripheral surface is inserted, when the unauthorized access to seal target portion alpha ₁ has been tried is the head 120 (in particular, the flange portion 122) of broken or whitening such a wide range of Traces will be formed. Therefore, it is possible to leave a mark that is difficult to erase with an adhesive or the like to remain on the gaming machine sealing member 100. In addition, even when the gaming machine sealing member 100 is inserted into the sealing hole α, the evidence of unauthorized access remains on the head 120 which is easily visible from the front side of the sealing hole α. It also makes it easy to discover.

2.1.2 Special Notes In the following, regarding the gaming machine sealing member 100 according to the first embodiment, several special matters to be noted will be listed.

(1) Color of Sealing Hole Insertion Part and Head As the synthetic resin material forming the head 120 and the sealing hole insertion part 110, it is preferable to select a transparent (including colored transparent) material. I already mentioned. In this respect, it is preferable that the head 120 and the sealing hole insertion portion 110 be colored and transparent, and the head 120 and the sealing hole insertion portion 110 be different colors. In the case where the head 120 and the sealing hole inserting portion 110 are of the same color (including the case where they are completely transparent), the flange portion 122 may be torn 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 is directly visible from the front side of the sealing hole α, a crack or a notch in the flange portion 122 The seal hole insertion portion 110 of the same color as the flange portion 122 can be seen through the portion where the frustration has occurred, and it may be difficult to notice that the flange portion 122 is broken or the like.

  In this respect, assuming that the head 120 and the sealing hole inserting portion 110 have different colors, as shown in FIG. 7B, when a crack β or a chipping occurs on the head portion 120 such as the flange portion 122, the The seal hole insertion portion 110 located on the back side of the head 120 is visible in a color different from that of the head 120 through the part where the tears β and the like are produced, and the tears β and the like are noticeable. It becomes difficult to overlook the existence of tears β and the like. Therefore, it is possible to easily detect a trace of unauthorized access (a crack β or a crack or the like generated on the head 120), and to prevent an unauthorized action on the gaming machine. Since the sealing hole insertion portion 110 is formed of a synthetic resin material having a strength higher than that of the head portion 120, the sealing hole insertion portion is formed even if a crack β or a chip or the like occurs in the head portion 120 during unauthorized access. It is considered that there is a high possibility that such a tear or chipping has not occurred at 110. As a coloring method of the head 120 and the sealing hole insertion portion 110, a method of adding a coloring material such as a pigment to the molding material (transparent synthetic resin material) of the head 120 and the sealing hole insertion portion 110 is exemplified. .

  By the way, although the aspect which makes the sealing hole insertion part 110 and the head 120 both colored and transparent different colors was demonstrated above, in the aspect which makes the sealing hole insertion part 110 and the head 120 different colors, In addition, [1] a mode in which both the seal hole insertion portion 110 and the head portion 120 are opaque and different colors, and [2] one of the seal hole insertion portion 110 and the head portion 120 is opaque and the other is transparent. (In addition to being colorless and transparent, including colored and transparent. The same applies to the following.) An embodiment in which the color is different (except that the head 120 is colorless and transparent), [3] Seal hole insertion portion 110 and head There is an aspect which makes one side 120 colorless and transparent and makes the other colored and transparent.

However, in the embodiment of the above [1] or [2], in the state where the gaming machine sealing member 100 is fitted into the sealing hole α, the sealing target portion of the back of the sealing hole α from the front side of the sealing hole α. it is difficult to visually confirm whether there is abnormality in alpha _1. In the embodiment of [3] above, when the sealing hole insertion portion 110 is colored and transparent and the head 120 is colorless and transparent, a crack β or a chipping occurs in the flange portion 122 or the like during unauthorized access. In the flange portion 122 etc., and the seal hole insertion portion 110 visible in the flange portion 122 etc. through the portion where the tears β and chips do not occur. The difference is not seen, and the existence of a crack β or a chip is easily overlooked. Furthermore, in the embodiment of [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 formed in the head 120 at the time of unauthorized access The portion 110 is transparent and inconspicuous, and it is easy to overlook the existence of the cracks β and chips. For the above reasons, it is preferable that the head 120 and the sealing hole insertion portion 110 be colored and transparent, and that the head 120 and the sealing hole insertion portion 110 be different in color.

  However, even if the sealing hole insertion portion 110 and the head portion 120 are different in color, when they are similar colors from each other, from the crevice β or chip or the like generated in the head portion 120 at the time of unauthorized access, Even if the seal hole insertion portion 110 located at the back side is seen, the inspector may not notice the difference in the color, and there is a possibility that the existence of a crack β or a chip may be overlooked. For this reason, it is preferable to make the color of the head 120 as different as possible from the color of the sealing hole insertion part 110. In the gaming machine sealing member 100 of the first embodiment, the color of the head 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 are in a complementary color relationship” means that the color of the head 120 is the complementary color of the color of the sealing hole insertion portion 110 (in the hue circle of the Munsell system However, the present invention is not limited to the case where the color of the sealing hole insertion portion 110 is the opposite of the position where the color of the sealing hole insertion portion 110 is located. In the “complementary color relationship” in the present specification, the color of the head 120 is within a range of 90 ° or less on both sides from the position where the true complementary color of the color of the sealing hole insertion portion 110 is located in the hue circle of the Munsell system When viewed from the center of the ring, the color is located in the range from the point where the color complement of the seal hole 110 is located by 90 ° in the counterclockwise direction to the point where it goes 90 ° in the clockwise direction. Are also included. For example, when the color of the sealing hole insertion portion 110 is "5R" in the color wheel of the Munsell system, the color of the head 120 is "10Y" to "5BG" (correct color) to "10PB" of the same color ring. It is assumed that “the color of the head 120 and the color of the sealing hole insertion portion 110 are in a complementary color relationship” within the range of 180 °. In this specification, the angle from the location where the color of the seal hole insertion portion 110 is located to the location where the color of the head 120 is located in the hue circle of the Munsell system (the angle from the center of the same hue circle The absolute value may be referred to as “a shift angle from the true complementary color of the color of the sealing hole insertion portion 110 to the color of the head 120”.

  The deviation angle from the color of the sealing hole insertion portion 110 to the color of the head 120 is 54 ° or less (for example, when the color of the sealing hole insertion portion 110 is “5R” in the color wheel of the Munsell system Preferably, the color of the head 120 is in the range of “10GY” to “5BG” (correct color) to “10B” of the same color wheel. The deviation angle from the color of the sealing hole insertion portion 110 to the color of the head 120 is 36 ° or less (for example, when the color of the sealing hole insertion portion 110 is “5R” in the color wheel of the Munsell system To make the color of the head 120 a color in the range of “5G” to “5BG” (correct color) to “5B” of the same hue ring, and to be 18 ° or less (for example, sealing hole insertion) When the color of the part 110 is "5R" in the color wheel of the Munsell system, the color of the head 120 is changed to a color in the range of "10G" to "5BG" (correct color) to "10BG" of the same color ring. More preferable.

(2) sealing the hole insertion part of the sealing hole inserting portion 110 for form, as long as it can engage the engaged portion alpha ₃ in the inner portion of the sealing hole alpha inserted into seal bore alpha, in particular its form It is not limited. In the game machine sealing member 100 according to the first embodiment, as shown in FIG. 5, the sealing hole insertion portion 110 is formed of a substantially cylindrical main body 111 and a base end side of the main body 111 (y axis in FIG. It comprises with the closed part 112 which closes the end side by the side of the direction negative.

When the main body 111 of the sealing hole inserting portion 110 is formed into a substantially cylindrical shape having a hollow portion without being a solid structure, when the game 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) described above can be secured can be secured inside the main body portion 111, as compared with the case where the main body portion 111 has a solid structure, It is possible to secure a long sealing hole insertion portion 110. In addition, it is possible to reduce the amount of material used for molding the game machine sealing member 100 and to reduce the manufacturing cost of the game machine sealing member 100. Further, in the gaming machine sealing member 100 of the first embodiment, as described later, the body portion 111 of the sealing hole inserting portion 110 to engage with the engaged portion alpha ₃ provided in the sealing hole alpha Where the engaging portion 111c is provided, when the gaming machine sealing member 100 is fitted in the sealing hole, the engaging portion 111c can be elastically displaced easily.

On the other hand, the closed portion 112 of the sealing hole insertion portion 110 is formed in a continuous surface shape having no opening and the like. This is sealed target portion alpha ₁ from the outside of the seal bore alpha, in order to prevent unauthorized access through the hollow portion of the main body portion 111 is not performed. In the gaming machine sealing member 100 according to the first embodiment, the head 120 of the gaming machine sealing member 100 has the central portion 121, and unauthorized access through the hollow portion of the main body portion 111 is performed by the central portion 121. The closure 112 is not an essential part as it can be prevented. However, in the gaming machine sealing member 100 according to the first embodiment, as described above, both the sealing hole insertion portion 110 including the closing portion 112 and the head 120 including the central portion 121 are colored and transparent. When the sealing hole insertion portion 110 and the head portion 120 have different colors, breakage or the like generated in the central portion 121 by positioning the closed portion 112 on the back surface side (the positive side in the y-axis direction) of the central portion 121. It makes marks such as whitening more noticeable.

  The outer surface shape of the main body portion 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. As the outer surface shape of the main body portion 111, a shape having only a curved surface like a cylinder or an elliptic cylinder, a shape having only a flat surface like a polygonal cylinder, a shape having a mixture of a curved surface and a flat, etc. Ru. In the gaming machine sealing member 100 according to the first embodiment, the outer surface of the main body 111 has a shape having a pair of flat portions 111a and a pair of curved portions 111b, as shown in FIG. It corresponds to the inner surface shape of α. The outer peripheral surface of the main body portion 111 in the vicinity of the tip end is formed in a tapered shape to facilitate insertion of the sealing hole insertion portion 110 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 engaging portion 111c, a stopper projection 111d, and a disturbing projection 111e.

The engaging portion 111 c is provided on the outer peripheral portion of the sealing hole insertion portion 110. The engaging portion 111 c is configured such that the sealing hole insertion portion 110 is provided in the sealing hole α so that the sealing hole insertion portion 110 inserted into the sealing hole α can not be pulled out from the sealing hole α. It is a part for engaging with ₃ . The engaging portion 111 c may be provided at other than the end of the main body 111, but in the gaming machine sealing member 100 of the first embodiment, it is provided at the end of the main body 111. Thus, the engagement portion 111c after the gaming machine sealing member 100 is fitted into the sealing hole α can be positioned on the back side of the sealing hole α. Therefore, even if an unauthorized device such as a minus driver 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 unauthorized device does not easily reach the engagement portion 111c. It is possible to make it difficult to release the engagement of the engagement portion 111 c improperly.

  The engaging portion 111 c 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. Thus, by providing the engaging portion 111c at a plurality of locations, an unauthorized device such as a minus driver 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. When trying to release the engagement of the engaging portion 111 c illegally, it is necessary to release the plurality of engaging portions 111 c, and it is possible to take time to release the engagement of the engaging portion 111 c. It is.

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

  At this time, the engaging portion 111c may be provided on the flat surface portion 111a of the peripheral wall of the main body portion 111. However, in the gaming machine sealing member 100 of the first embodiment, the engaging portion 111c is provided on the curved surface portion 111b of the peripheral wall of the main body portion 111. ing. As a result, it becomes possible to make it difficult to conduct fraudulent acts using a fraudulent instrument whose tip is formed like a flat plate like a flathead screwdriver. The reason is that a fraudulent insertion tool whose tip is formed in a plate shape 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 engageable 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, the convex part which protrudes outward from the outer peripheral surface of the sealing hole insertion part 110 is made into the engaging part 111c. When the game machine sealing member 100 is fitted into the sealing hole α, the convex portion (engaging portion 111c) is a front side (y-axis direction negative side) in the fitting direction of the convex portion (engaging portion 111c). Is engaged with the engaged portion α ₃ provided in the sealing hole α (in the example of FIG. 4, the open end face of the back side (y-axis direction positive side) of the peripheral wall surrounding the sealing hole α) It has become a thing.

The outer surface of the convex portion (engaging portion 111c) (the surface facing the outer side when viewed from the center line of the main body portion 111) is, as shown in FIG. It is formed in a state of being inclined so as to largely project outward toward the axial negative side). In addition, as shown in FIG. 5, slits are provided on both sides of the convex portion (engaging portion 111 c), and the convex portion (engaging portion 111 c) is a main body portion 111 only in the band plate portion. It is in a connected state. For this reason, when inserting the gaming machine sealing member 100 into the sealing hole α, the outer surface of the convex portion (engaging portion 111c) smoothly contacts the inner peripheral surface of the sealing hole α, and the convex portion (engagement portion The portion 111c) is displaced to the inside of the main portion 111 without any strain, and the convex portion (engaging portion 111c) is not caught on the inner peripheral portion of the sealing hole α, and the game machine sealing member 100 is moved to a predetermined depth (convex portion). (engaging portion 111c) is adapted to be inserted smoothly to a depth) to overcome the engaged portion alpha _3. If for a game machine seal member 100 is pushed to a predetermined depth, by the convex portions (the engaging portion 111c) is elastically restored to the initial position, engaging projection (engaging portion 111c) is the engaged section alpha ₃ United.

  By the way, in the gaming machine sealing member 100 of the first embodiment, as described above, when the closing portion 112 is provided in the sealing hole insertion portion 110, the near side (the y axis direction negative side) of the closing portion 112 As shown in FIG. 5, the character string "YAMASA" is engraved on the surface facing the face. As a result, it becomes possible to make the forgery of the game machine sealing member 100 difficult. Also, if breakage, whitening, or the like occurs in the central portion 121 of the head 120 of the game machine sealing member 100 during unauthorized access, it becomes difficult to visually recognize characters displayed on the closed portion 112, As compared with the case where the characters are not shown in the closed portion 112, it is easy to notice that the central portion 121 is broken or whitened. The closing unit 112 may represent figures, symbols, etc. instead of characters.

  A mode in which a character, a figure, a symbol or the like (hereinafter sometimes referred to as a “character or the like”) is engraved on the closed portion 112 is a mode in which a portion such as a character is provided protruding from a surrounding portion Examples include a mode in which a character or the like is provided as a convex portion) and a mode in which a portion such as a character is provided in a recessed state from its periphery (a mode in which a character or the like is provided as a recess). Either of these may be adopted, but as described above, in the case where the sealing hole insertion portion 110 and the head portion 120 in the game machine sealing member 100 are molded in two colors, a synthetic resin system for molding the head portion 120 In consideration of the flow of the synthetic resin material at the time of injecting the material, it may be preferable to provide characters and the like as a recess.

The stopper projection 111d is, as shown in FIG. 5, from a location at a predetermined distance on the tip side (the positive side in the y-axis direction) than the location where the flange portion 122 is provided in the outer peripheral portion of the sealing hole insertion portion 110. It is provided to project outward. The stopper projection 111d abuts the counterbore surface α ₂ (FIG. 4) of the sealing hole α when the gaming machine sealing member 100 is fitted into the sealing hole α, and the gaming machine sealing member 100 is sealed. The part functions as a stopper for preventing further movement to the back of the hole α. Therefore, the stopper protrusion 111d is tenaciously formed to withstand the pressing force received from the counterbore surface alpha _2.

  The stopper projection 111d may be formed continuously on the entire periphery of the outer periphery of the sealing hole insertion portion 110. In this case, the portion for injection molding the stopper projection 111d is annularly formed in a wide range. Since it comes to be formed, there is a possibility that a trouble may easily occur when injection molding the sealing member 100 for a gaming machine. Therefore, in the gaming machine sealing member 100 according to the first embodiment, the stopper projection 111d is a total of two each in the pair of curved surface portions 111b, one each in the pair of flat portions 111a in the sealing hole insertion portion 110. It is divided into six places.

  As shown in FIG. 5, the obstructive protrusion 111e is on the distal end side (positive side in the y-axis direction) than the stopper protrusion 111d in the outer peripheral portion of the sealing hole insertion portion 110 and is proximal to the engaging portion 111c. It protrudes outward from a position on the side (the negative side in the y-axis direction). In the game machine sealing member 100 according to the first embodiment, as described above, the stopper projections 111d are provided separately at a plurality of locations, and the stopper projections are provided on the outer peripheral portion of the sealing hole insertion portion 110. There is a section in which the section 111d does not exist, but the projection 111e for disturbing is a section in which the projection 111d for a stopper does not exist, and from the center line direction (y-axis direction) of the game machine sealing member 100. It is provided at a position overlapping the engaging portion 111 c when viewed. In the gaming machine sealing member 100 according to the first embodiment, the two engaging portions 111c are provided in opposite directions in a symmetrical position when viewed from the center line of the main body portion 111. , And are provided in opposite directions at positions symmetrical with respect to the center line of the main body 111.

Thus, a section in which the person who attempts to release the engaging portion 111 c illegally overlaps the engaging portion 111 c in the gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the sealing hole insertion portion 110 (protrusion portion 111 d for stopper Even if a fraudulent device such as a flat-blade screwdriver is properly inserted from the space where no distraction is provided, the fraudulent device is disturbed by the obstructive projection 111e, and the fraudulent device reaches the location where the engaging portion 111c is provided. It will be possible not to. In the gaming machine sealing member 100 according to the first embodiment, each of the interfering projections 111e is inserted between a pair of convex streaks α ₄ (FIG. 4) provided on the inner peripheral portion of the sealing hole α. has become, if not destroy the projections alpha ₄ and baffle projections 111e, it has become difficult to release the engagement portion 111c from the front side of the sealing hole alpha.

(3) Regarding the Form of the Head As described above, the head 120 is composed of the flange portion 122 and the central portion 121. Flange portion 122 is formed into a shape capable of blocking the front side of the pocket surface alpha ₂ in sealing holes alpha. For this reason, the flange portion 122 is normally formed continuously on the entire periphery of the proximal end outer peripheral portion of the sealing hole insertion portion 110. On the other hand, the central portion 121 is formed to close the inner region of the flange portion 122. The protruding length L ₁ (FIG. 6) of the flange portion 122 is not particularly limited, but if it is too short, the gap between the inner peripheral surface of the sealing hole α and the outer peripheral surface of the sealing hole insertion portion 110 is covered with the flange portion 122 There is a risk that you will not be able to In addition, when an unauthorized tool such as a minus driver is inserted into the gap, the flange portion 122 may not be easily broken or whitened. Therefore, the projecting length _{L 1} of the flange portion 122 is generally a 1mm or more. Protruding length _{L 1} of the flange portion 122 are preferably When 1.5mm or more, and more preferably a 2mm or more. No particular upper limit on the protruding length _{L 1} of the flange portion 122, but is typically up to about 10 mm. The flange portion 122 is usually formed more fragile than the stopper projection 111d.

2.2 Game Machine Sealing Member of Second Embodiment Next, the game machine sealing member 100 of the second embodiment will be described. Regarding the gaming machine sealing member 100 of the second embodiment, mainly, portions different from the gaming machine sealing member 100 of the first embodiment described above will be described. About the composition of the portion which does not especially mention about the sealing member 100 for game machines of the 2nd embodiment, since it is substantially the same as what was described by the sealing member 100 for game machines of the first embodiment, it omits explanation.

  FIG. 8 is a perspective view showing the state of the gaming machine sealing member 100 of the second embodiment as viewed from (a) front diagonally upper right and (b) as viewed from the rear diagonal upper right. FIG. 9 is a perspective view showing a state where 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 FIGS. 8 and 9, only the sealing hole inserting portion 110 is shown by hatching in order to make it easy to distinguish between the sealing hole inserting 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 where the gaming machine sealing member 100 of the second embodiment is cut in a plane including the center line of the gaming machine sealing member 100 and parallel to the yz plane.

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

Thereby, in the case where unauthorized access is attempted to the sealing target location α ₁ by an unauthorized appliance being 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, etc. 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 Clefts etc.) can easily occur. In this case, the seal hole insertion portion 110 located on the back side can be easily seen in a color different from that of the head portion 120 from a portion (a crack β or the like) in the flange portion 122 where a crack or the like occurs. Therefore, when unauthorized access is attempted, it is possible to easily form the mark of the more difficultly erased and more conspicuous aspect on the head 120 including the flange portion 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 insertion portion 110 (in particular, a section overlapping on the front side of the engaging portion 111c).

However, when the projection length L ₂ of the convex portion 110a is too short, necessarily the dimensions of the convex portion 110a is reduced, the convex portion 110a over the entire circumference of the proximal end outer peripheral portion of the sealing hole inserting portion 110 In order to provide it, it will be necessary to form a large number of fine projections 110a. Therefore, molding of the sealing hole inserting portion 110 becomes difficult, there is a possibility that hardly sharpened to form edges 110a ₁ of the convex portion 110a. Therefore, the projection length _{L 2} of the convex portion 110a is usually a 0.3mm or more. Projection length _{L 2} of the convex portion 110a is preferably set to 0.5mm or more, and more preferably to 0.7mm or more. On the other hand, when the projection length L ₂ of the convex portion 110a is too close to the protruding length L ₁ of the flange portion 122, an illegal device the gap between the inner and outer circumferential surfaces of the flange portion 122 of the sealing hole α insert At the same time, there is a possibility that traces such as breakage and whitening are less likely to occur on the flange portion 122. Therefore, the ratio _L 2 / _{L 1} of the projecting length _{L 2} of the convex portion 110a against the protruding length _{L 1} of the flange portion 122 is preferably set to 0.7 or less. The ratio L ₂ / L ₁ is more preferably 0.6 or less and still more preferably 0.5 or less.
