Description

  The present invention relates to a gaming machine protective cover for protecting parts to be protected such as various boards in gaming machines from fraud, and a gaming machine provided with the gaming machine protective cover.

  Gaming machines can be subject to various cheating activities. For example, a main control board is accommodated inside the housing of the gaming machine, and a storage device (usually ROM) in which a program for controlling the gaming machine is recorded is mounted on the main control board. 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 type of fraud, each manufacturer of gaming machines has a structure in which the parts to be protected, such as the main control board, covered by fraud are covered with a cover (protective cover for gaming machines). In order to close the cover, a sealing member is fitted into a place (screw hole or the like) that is screwed or the like, and measures are taken to seal the place. As a result, even if unauthorized access to a screwed part or the like is permitted, traces of unauthorized access remain on the sealing member, thereby making it easy to detect unauthorized acts.

  For example, FIG. 6 of Patent Document 1 shows a shielding cap 50 (sealing member) made of a resin material, which includes a cylindrical portion 51, a flange portion 52 formed at the upper end of the cylindrical portion 51, and an outer periphery of the cylindrical portion 51. The flange portion 52 is provided with a rectangular opening 54, a lid portion 55 is disposed on the inside thereof, and the lid portion 55 and the flange portion 52 are thinly connected. What was connected with the part 56a and the connection part 56b is described (paragraphs 0025-0026 of the literature). As a result, as shown in FIG. 11 of the same document, unless the lid portion 55 is pushed down to break the connecting portion 56b and the thin-walled connecting portion 56a is bent and the periphery thereof is not whitened, the screwed portion is illegal. It is said that it is possible to prevent access (paragraph 0032 of the same document).

  However, with the shielding cap 50 (sealing member) of Patent Document 1, as long as the shielding cap 50 (sealing member) itself is replaced with a new one, traces of unauthorized access can be completely erased, and fraud is discovered. There was the disadvantage that it was virtually impossible to do. In recent years, the persons who cheat on gaming machines have been organized, and among them, there are organizations that produce counterfeit products of sealing members. In this way, for those who can manufacture a counterfeit product of the sealing member, the sealing member of Patent Document 1 has almost no deterrent effect.

JP 2003-340092 A

  The present invention has been made in order to solve the above-mentioned problem, and only by exchanging the sealing member with a counterfeit product, the trace of unauthorized access cannot be erased, and the effect of suppressing unauthorized acts is high. A protective cover for gaming machines is provided. It is also an object of the present invention to provide a gaming machine provided with this gaming machine protective cover.

The above issues
A cover body for covering the parts to be protected;
A sealing member for fitting into a sealing target hole provided in the cover body and sealing the sealing target hole;
A protective cover for a gaming machine comprising
The cover body and the sealing member are connected to each other via a flexible connection sheet,
The end of the connecting sheet that is connected to the cover main body (hereinafter sometimes referred to as “the base end of the connecting sheet”) is fixed in a state of being embedded in the cover main body,
A gaming machine characterized in that an end portion of the connecting sheet connected to the sealing member (hereinafter, sometimes referred to as a “tip portion of the connecting sheet”) is fixed in an embedded state in the sealing member. It is solved by providing a protective cover.

  Here, the “parts to be protected” refers to parts for gaming machines that need to be protected in order to limit unauthorized access thereto. Specific examples of the parts to be protected include a storage device in which a program for controlling the gaming machine is recorded, an electronic board on which the storage device is mounted, a case housing these, and the like. However, it is not limited to this.

  Further, the “sealing target hole” refers to a hole portion provided in the cover main body and to be sealed. Holes to be sealed are provided in the cover body in order to fix a fixing tool (screw, etc.) for fixing the cover body to other members (a cover holder assembled to the cover body, a housing of a gaming machine, etc.) For example, the hole (such as a counterbore for screwing) is illustrated. The inner peripheral surface of the sealing target hole does not necessarily have to be formed continuously from the entrance to the back of the sealing target hole.

  Furthermore, “fixed with the base end portion of the connecting sheet embedded in the cover body” means that at least a part of both front and back surfaces of the base end portion of the connecting sheet is sandwiched between molding materials (resin etc.) of the cover body. It is in a state (a state in which both of the front and back surfaces are in contact with the molding material of the cover body), and the sandwiched portion of the base end portion of the connection sheet is integrated with the cover body. Say that. For example, after fixing the connection sheet in the mold for injection molding of the cover body, the fixing of this aspect is performed by pouring the molding material of the cover body into the mold and injection molding (the cover body and the connection sheet. This can be realized by integrating the cover body when injection molding.

  Furthermore, “fixed in a state in which the leading end of the connecting sheet is embedded in the sealing member” means that at least a part of the front and back surfaces of the leading end of the connecting sheet is sandwiched between molding materials (resin etc.) of the sealing member. (A state where both the front and back surfaces of the part are in contact with the molding material of the sealing member) and that the sandwiched portion at the tip of the connecting sheet is integrated with the sealing member. say. In this aspect, for example, after a connecting sheet is arranged in advance in a mold for injection-molding the sealing member, the molding material for the sealing member is poured into the mold and injection-molded (the sealing member and the connecting sheet are combined). This can be realized by integrating the sealing member when injection molding.

  In the protective cover for gaming machines of the present invention, as described above, in addition to the cover main body and the sealing member being connected to each other via the connection sheet, the base end portion and the tip end portion of the connection sheet are respectively covered. Since it is fixed in a state where it is embedded in the main body and the sealing member, the trace of unauthorized access cannot be erased by replacing only the sealing member with a counterfeit product.

  Specifically, in the protective cover for gaming machines of the present invention, when only the sealing member is replaced with a counterfeit, it is necessary to remove the sealing member from the connecting sheet. However, since the leading end of the connecting sheet is fixed in a state where it is embedded in the sealing member, the sealing member cannot be removed from the connecting sheet unless the connecting sheet is broken in the vicinity of the leading end. Yes. In this case, a breakage mark or the like of the connection sheet is recognized as a trace of unauthorized access.

  Further, in the protective cover for gaming machines of the present invention, when both the sealing member and the connection sheet are to be replaced with counterfeit products, it is necessary to remove the connection sheet from the cover body. However, since the base end portion of the connecting sheet is fixed in a state where it is embedded in the cover body, the connecting sheet is broken near the base end portion or the vicinity of the portion connected to the connecting sheet in the cover body is destroyed. Unless it is equal, the connecting sheet cannot be removed from the cover body. In this case, a breakage mark of the connection sheet, a breakage mark of the cover body, and the like are recognized as a trace of unauthorized access.

  In other words, the protective cover for gaming machines of the present invention cannot completely erase the trace of unauthorized access only by replacing some members such as a sealing member and a connecting sheet. In the protective cover for gaming machines of the present invention, if the trace of unauthorized access is to be completely erased, it is necessary to replace all of the sealing member, the connecting sheet and the cover body with counterfeit products. For this reason, the protective cover for gaming machines of the present invention is very difficult to cheat and has a high deterrent effect. Moreover, in the protective cover for game machines of this invention, since the cover main body and the sealing member are mutually connected via the connection sheet, it is also possible to prevent the loss of a sealing member.

  In the protective cover for gaming machines of the present invention, the sealing member before being fitted into the sealing target hole may be only connected to the cover main body via the connecting sheet. However, in this case, when the gaming machine protective cover is transported or when the gaming machine protective cover is fixed to the other member, the sealing member is hung from the cover body via the connecting sheet. May collide with the cover main body or the like, and the sealing member or the cover main body may be damaged. For this reason, there is a possibility that it is misunderstood that the fraudulent act has been performed due to the damage mark even though the fraudulent act has not been performed. Therefore, it is preferable that the sealing member before being fitted into the sealing target hole is held in the cover body.

  Although the structure which hold | maintains the sealing member before fitting in the sealing object hole with respect to a cover main body is not specifically limited, For example, the following structures are mentioned. That is, a sealing member accommodating portion for accommodating the sealing member before fitting into the sealing target hole together with the connecting sheet is provided around the sealing target hole in the cover main body, and the connecting sheet accommodated in the sealing member accommodating portion is the cover main body. It is the structure which provides a fixed part at the time of accommodation for fixing to a connection sheet. Accordingly, it is possible to further prevent the sealing member and the cover body from being damaged when the protection cover for the gaming machine is transported without separately preparing a jig or the like for housing the sealing member.

  At this time, a method for fixing the connecting sheet fixing portion to the cover body is not particularly limited, but the connecting sheet fixing portion accommodated in the sealing member accommodating portion is embedded in the cover main body. It is preferable to fix. Here, the phrase “fixed in the state in which the fixing part is embedded in the cover body when the connecting sheet is accommodated” means in the description of “fixing in the state in which the base end part of the connecting sheet is embedded in the cover body”. This is the same as the “base end part” of the above in which “fixed part at the time of accommodation” is replaced. For example, after fixing the connection sheet in the mold for injection molding of the cover body, the fixing of this aspect is performed by pouring the molding material of the cover body into the mold and injection molding (the cover body and the connection sheet. This can be realized by integrating the cover body when injection molding. When fixing with the fixing part embedded in the cover body, the periphery of the connecting sheet fixing part is cut with a cutting tool such as a scissors or a cutter or manually, and the fixing part is stored in the other part of the connecting sheet. The sealing member is fitted into the sealing target hole in a state where the sealing member is separated from the sealing target hole.

  In this way, by fixing the fixing part in the state where the connecting sheet is accommodated while being embedded in the cover body, there appears a person who tries to replace the genuine connecting sheet that has been left in the case of fraudulent acts with a counterfeit product. Even in such a case, in order to completely erase the trace of fraud, the person needs to reproduce up to the cutting line of the cutting around the fixing portion at the time of accommodation in the connecting sheet. For this reason, it becomes possible to make it more difficult to replace the counterfeit product with the connection sheet. In addition, if the fixing part for storage is adhered to the surface of the cover body, or if the fixing part for storage is engaged with the irregularities on the surface of the cover body, irregularities are inevitably formed on the surface of the cover body. When the protective cover is transported or the like, the unevenness may be caught by another member or the like. By embedding the fixing portion in the housing, it is possible to prevent such a problem from occurring.

  In the protective cover for gaming machines of the present invention, the connecting sheet after the sealing member is fitted into the sealing target hole is in a free state except for the base end portion and the distal end portion (other body such as the cover main body and the sealing member). (The state which is not being fixed to the member) may be sufficient. However, as described below, it is preferable that the connecting sheet after the sealing member is fitted in the sealing target hole has a structure that can be fixed to the cover body at a portion other than the base end portion and the tip end portion. That is, after fitting the sealing member in the sealing target hole in the connecting sheet, the fixing portion is provided in the portion overlapping the periphery of the sealing target hole, and the sealing member in the cover body is fitted in the sealing target hole. A fixed part after fitting is provided in a portion overlapping the fixed part after fitting of the connecting sheet, and the fixed part after fitting is fixed to the fixed part after fitting when the sealing member is fitted into the sealing target hole. By this, it is a structure which prevents the part located in the circumference | surroundings of the sealing object hole in the connection sheet | seat after fitting a sealing member in the sealing object hole from a cover main body.

  This is because a gap formed between the outer peripheral surface of the sealing member fitted in the sealing target hole and the inner peripheral surface of the sealing target hole (hereinafter sometimes referred to as “inserting clearance”) is minus. It is assumed that there are some people who try to remove the sealing member from the sealing target hole by inserting an unauthorized insertion tool such as a screwdriver. This is because it is difficult to insert the unauthorized insertion tool into the fitting gap without damaging the connecting sheet so as to be covered with the sheet. An engaging portion is provided on the outer peripheral portion of the sealing member, an engaged portion is provided on the inner peripheral portion of the sealing target hole, and when the sealing member is fitted into the sealing target hole, the engaging portion and the engaged portion When the two are engaged with each other, it is more preferable that the portion of the fitting gap located above the engaging portion and the engaged portion is covered with the connecting sheet. As a result, even if an unauthorized insertion tool is inserted into the fitting gap and the engagement between the engaging portion and the engaged portion is released, the upper connecting sheet can be in the way. Become.

  In the protective cover for gaming machines of the present invention, the edge of the portion of the cover body in which the connection sheet is embedded (the edge of the cover body where the connection sheet embedded in the cover body is exposed from the cover body) is formed in a straight line. However, it is preferably formed in a non-linear shape (such as a broken line shape or a curved shape). Because, if the edge is straight, it is easy to cut the vicinity of the base end portion of the regular connection sheet along the edge into a beautiful straight line, whereas the edge is non-linear. This is because it is difficult to cleanly clean the vicinity of the base end portion of the regular connection sheet along the edge. In the former case, it is easy to join the counterfeit product connection sheet in a relatively inconspicuous state along the cutting line of the genuine connection sheet, and both the sealing member and the connection sheet are replaced with a counterfeit product. In the latter case, it is difficult to recognize the trace, and it is difficult to join the counterfeit connection sheet along the cutting line in the genuine connection sheet. Even when both sheets are replaced with counterfeit goods, the traces can be easily recognized.

  In the protective cover for gaming machines of the present invention, the portion exposed to the outside in the vicinity of the portion embedded in the sealing member in the connection sheet may be formed with the same width as other portions (intermediate portion or the like) in the connection sheet. However, it is preferable to form a narrower width than the other parts of the connecting sheet. Accordingly, the genuine connection sheet is cut along the edge of the portion of the sealing member where the connection sheet is embedded (the edge of the portion of the sealing member where the connection sheet embedded in the sealing member is exposed from the sealing member). Even if the sealing member is removed and the forged sealing member is joined along the cutting line in the regular connection sheet connected to the cover body, the joining itself can be made difficult. Therefore, it is possible to make it difficult to replace only the sealing member with a counterfeit product.

  The above-described protective cover for gaming machines of the present invention can be suitably used as a protection target for parts to be protected in various gaming machines such as a swivel type gaming machine and a pachinko gaming machine.

  As described above, according to the present invention, it is not possible to erase the trace of unauthorized access only by exchanging the sealing member with a counterfeit product, and to provide a protective cover for gaming machines with a high deterrent effect. Is possible. It is also possible to provide a gaming machine equipped with this gaming machine protective cover.

  As shown in FIGS. 4 and 5, the gaming machine protective cover 100 according to this embodiment includes a cover main body 110, a sealing member 120, and a connecting sheet 130. The cover main body 110 and the sealing member 120 are connected to each other via the connection sheet 130. The base end portion of the connection sheet 130 is fixed in a state of being embedded in the cover main body 110, and the distal end portion of the connection sheet 130 is fixed in a state of being embedded in the sealing member 120. Hereafter, each member which comprises the protective cover 100 for game machines is demonstrated in detail.

2.1 Cover Body The cover body 110 is a member for covering the parts to be protected (the main control board case 30a and the sub control board case 30b in FIG. 3 in the gaming machine protective cover 100 of this embodiment). ing. The cover body 110 is not particularly limited in its specific form as long as the protection target component can be protected in a desired state. In the protective cover 100 for gaming machines of the present embodiment, the cover body 110 has a substantially rectangular shape when viewed from the front and has a substantially box-like body with the back side open as shown in FIGS. . The molding material of the cover body 110 is usually a resin. The resin used for forming the cover main body 110 may be one that does not have visibility (translucency), but is preferably one that has visibility (including a transparent one). Examples of the resin having visibility include polycarbonate, acrylic, ABS resin, PET resin, and polystyrene. As a result, it becomes possible to visually recognize the inside of the protective cover 100 for gaming machines from the outside, and the state of the base end portion of the connecting sheet 130 embedded in the cover main body 110, thereby further discovering fraud. It becomes possible to make it easier. In the protective cover 100 for gaming machines of this embodiment, the cover main body 110 is formed by injection molding transparent polycarbonate.

  The cover main body 110 is provided with a sealing target hole 111. The sealing target hole 111 is provided at a location where the gaming machine protective cover 100 (cover 30d in FIG. 3) is screwed to the holder 30c (see FIG. 3). Screwing of the gaming machine protective cover 100 to the holder 30c is performed at the back of the sealing target hole 111 (broken line portion A in FIG. 5). The number and arrangement of the sealing target holes 111 are not particularly limited. In the gaming machine protective cover 100 of the present embodiment, as shown in FIG. 4, when the gaming machine protective cover 100 is viewed from the front side, the upper left corner and the lower left corner of the cover main body 110 are shown. And the sealing object hole 111 is provided in a total of three places with the corner | angular part used as an upper right. In the following, the sealing target hole 111 provided in the upper left corner of the cover body 110, the sealing target hole 111 provided in the lower left corner, and the sealing target hole provided in the upper right corner. May be referred to as “upper left sealing target hole 111”, “lower left sealing target hole 111”, and “upper right sealing target hole 111”, respectively.

  As shown in FIG. 5, an engaged portion 111 a is provided in the inner peripheral portion of the sealing target hole 111. The engaged portion 111 a is a portion for engaging with the engaging portion 121 a provided on the outer peripheral portion of the sealing member 120 when the sealing member 120 is fitted into the sealing target hole 111. On both sides of the engaged portion 111a in the inner peripheral portion of the sealing target hole 111, baffle protrusions 111c are provided. Thereby, an unauthorized insertion tool such as a flat-blade screwdriver is inserted into the gap (insertion gap) between the outer peripheral surface of the sealing member 120 and the inner peripheral surface of the sealing target hole 111 to release the engagement of the engaging portion 121a. Even if it does, it becomes possible to prevent the front-end | tip of an unauthorized insertion tool from reaching the engaging part 121a because the baffle protrusion 111c becomes an obstacle.

  The engaged portion 111a may be provided at a plurality of locations, but is provided only at one location in the gaming machine protective cover 100 of the present embodiment. The arrangement of the engaged portion 111a is not particularly limited. However, in the gaming machine protective cover 100 of this embodiment, as shown in FIG. 12, when the sealing member 120 is fitted into the sealing target hole 111, The upper part is arranged at a place covered with the connecting sheet 130. Specifically, the engaged portion 111a is provided on the inner peripheral portion of the sealing target hole 111 on the side where the sealing member accommodating portion 112 described later is provided. Thus, even if an unauthorized insertion tool such as a flat-blade screwdriver is inserted into the fitting gap to release the engagement portion 121a, the connection sheet 130 becomes in the way, It is possible to make it difficult to release the engagement without leaving a trace. Therefore, when such a fraudulent act is performed, it is possible to easily find out that the fraudulent act has been performed.

  As shown in FIGS. 4 and 5, a sealing member accommodating portion 112 is provided around the sealing target hole 111 in the cover main body 110. The sealing member accommodating portion 112 is a portion for accommodating the sealing member 120 before being fitted into the sealing target hole 111 together with the connecting sheet 130. The sealing member accommodating portion 112 may be provided only around the part of the sealing target holes 111, but in the protective cover 100 for gaming machines of the present embodiment, it is provided around all the sealing target holes 111. Specifically, the sealing member accommodating portion 112 (the upper left sealing member accommodating portion 112) for accommodating the sealing member 120 that fits into the upper left sealing target hole 111 is located below the upper left sealing target hole 111 (z axis). The sealing member accommodating part 112 (lower left sealing member accommodating part 112) for accommodating the sealing member 120 fitted in the lower left sealing target hole 111 is provided above the lower left sealing target hole 111 (z).

However, at the time of injection molding of the cover main body 110, the molding material of the cover main body 110 can be solidified in a state of entering the anchor hole 131. Therefore, the base end portion of the connection sheet 130 is covered unless the periphery of the anchor hole 131 at the base end portion of the connection sheet 130 is broken or the portion of the cover main body 110 where the connection sheet 130 is embedded is broken. It is possible to prevent the main body 110 from being pulled out.

  In the protection cover 100 for various gaming machines according to the present embodiment, the anchor hole 131 is provided at only one place at the base end portion of the connection sheet 130, but may be provided at a plurality of places. In addition, the anchor hole 131 may be provided in a portion that is fixed in a state where the anchor hole 131 is embedded in the sealing member 120 at the distal end portion of the connection sheet 130. This is because, in the protective cover 100 for gaming machines of the present embodiment, as will be described later, when the sealing member 120 is injection-molded, it is fixed (integrated) with the leading end portion of the connecting sheet 130 embedded in the sealing member 120. However, at the time of injection molding of the sealing member 120, the molding material of the sealing member 120 is solidified in a state of entering the anchor hole 131, so that the integrity of the connecting sheet 130 to the sealing member 120 can be improved. Because it becomes.

  The positioning hole 132 is a part for positioning the connection sheet 130. That is, in the gaming machine protective cover 100 of this embodiment, as will be described later, the cover main body 110 is placed in a mold for injection molding (hereinafter sometimes referred to as “cover main body molding mold”). When the connection sheet 130 (the connection sheet 130 with the sealing member 120 fixed to the front end portion) is arranged in advance, the positioning pin provided on the cover body molding die is inserted into the positioning hole 132 of the connection sheet 130. And it becomes easy to arrange | position the connection sheet | seat 130 in the correct position in the metal mold | die for a cover main body shaping | molding. The positioning holes 132 may be provided only at one location, but it is preferable to provide the positioning holes 132 at a plurality of locations in order to further improve the positioning accuracy of the connecting sheet 130 with respect to the cover body molding die. In the protective cover 100 for gaming machines of this embodiment, there are a total of four locations including the both sides of the anchor hole 131 at the base end portion of the connecting sheet 130 and the respective holding fixing portions 130b at the distal end portion of the connecting sheet 130. A positioning hole 132 is provided.

The engaging portion 134a and the engaged portion 113a are adapted to engage with each other when the protrusion in the fixed portion 134 after being inserted is pushed into the fixed portion 113 after being inserted to a predetermined depth. For this reason, the post-fitting fixing part 134 fixed to the fixed part 113 after fitting cannot be removed from the fixed part 113 after fitting. About the form of the engaging part 134a and the to-be-engaged part 113a, the form similar to the engaging part 121a and the to-be-engaged part 111a mentioned above is employable.

  Thus, the connection sheet | seat after fitting the sealing member 120 in the sealing object hole 111 as shown in FIG. 12 by enabling the fixing part 134 after insertion to be fixed to the to-be-fixed part 113 after fitting. It is possible to prevent a portion located around the sealing target hole 111 in 130 from floating from the cover main body 110. Therefore, with the intention of pulling out the sealing member 120 from the sealing target hole 111, an unauthorized insertion tool such as a flat-blade screwdriver is inserted into the above-mentioned insertion gap, and the engagement between the engaging portion 121a and the engaged portion 111a is released. Even if there is a person who tries to do so, the connecting sheet 130 is likely to become an obstacle, and the engaging portion 121a and the engaged portion 111a are disengaged without damaging the connecting sheet 130 (leaving a trace of fraud). This can make it even more difficult. In the protective cover 100 for gaming machines of this embodiment, in the sealed state in which the sealing member 120 is fitted in the sealing target hole 111, the portions located above the engaging portion 121a and the engaged portion 111a in the fitting gap are connected.

The branch part 130a is locally fixed to both end parts (both end parts in the x-axis direction in the figure) of the sealing member 120. For this reason, the width W ₁ (see FIG. 8) of the portion embedded in the sealing member 120 at the distal end portion of the connection sheet 130 is narrower than the width W ₂ (see FIG. 8) of other portions of the connection sheet 130. In the initial state in which the sealing member 120 is accommodated in the sealing member accommodating portion 112, the sealing member 120 can be maintained in a stable state in the sealing member accommodating portion 112. When narrowing the width W ₁ of the distal end portion of the connecting sheet 130, taken along the distal end portion of the connecting sheet 130 to the edge of the sealing member 120, remove the sealing member 120 from the connection sheet 130, the tip portion of the connecting sheet 130 Even if it is going to join the sealing member of a forgery product in the said cutting | disconnection location in, there exists an advantage that the joining itself becomes difficult and it becomes difficult to perform fraud.

A specific value for the width W ₁ of the distal end portion of the connecting sheet 130 is different depending on dimensions of seal member 120 is not particularly limited. However, the width _{W 1} of the distal end portion of the connecting sheet 130, when the ratio _W 1 / _{W 2} of width _{W 1} to width _{W 2} is set in a range of 0.5 or less preferred. The ratio W ₁ / W ₂ is more preferably 0.4 or less, and further preferably 0.3 or less. The lower limit of the ratio W ₁ / W ₂ is not particularly limited, but if the ratio W ₁ / W ₂ is too small, the sealing member 120 is fitted into the sealing target hole 111 when the protection cover 100 for gaming machines is transported. In some cases, the leading end of the connection sheet 130 may be easily broken. For this reason, the ratio W ₁ / W ₂ is usually 0.05 or more, and preferably 0.1 or more.

  Further, in the gaming machine protective cover 100 of the present embodiment, as described above, the leading end portion of the connection sheet 130 is branched into the pair of branch portions 130a, so that as shown in FIG. A blank portion 130c where the connecting sheet 130 does not exist is formed in a semicircular shape between the branch portions 130a. For this reason, when the sealing member 120 is fitted into the sealing target hole 111, a finger or the like that presses the lid 122 of the sealing member 120 is prevented from coming into contact with the connecting sheet 130, so that a flaw that may be mistaken as a trace of fraud Etc. can be prevented from being formed on the connecting sheet 130. In addition, when there is a situation in which the sealing member 120 must be removed from the sealing target hole 111 in regular maintenance such as replacement of a failed part, the lid portion 122 of the sealing member 120 is easily broken through the blank portion 130c. It is also possible to do.

3. Method for Producing Gaming Machine Protective Cover The gaming machine protective cover 100 according to the present embodiment described above is fixed with the base end portion of the connecting sheet 130 embedded in the cover body 110, and the leading end of the connecting sheet 130. The portion is fixed in a state of being embedded in the sealing member 120. The protective cover 100 for a gaming machine having such a structure includes, for example, the cover main body 110 and the sealing member 120 in a state where the connecting sheet 130 is disposed at a predetermined position in a mold for injection molding the cover main body 110 and the sealing member 120. The molding material can be injected into the mold and solidified. The injection molding of the cover main body 110 and the injection molding of the sealing member 120 may be performed simultaneously using a common mold, but in this case, different molding materials are used for the cover main body 110 and the sealing member 120. It becomes difficult. In this respect, as described above, the protective cover 100 for the gaming machine according to the present embodiment is such that the cover body 110 is made of transparent polycarbonate and the sealing member 120 is made of transparent ABS resin. The molding material different from 120 is adopted. As described above, when different molding materials are used for the cover main body 110 and the sealing member 120, the injection molding of the cover main body 110 and the injection molding of the sealing member 120 may be performed at different timings using different molds. Good.

  For example, as shown in FIG. 8, the connection sheet 130 cut into a predetermined shape is sealed in a state where it is disposed at a predetermined position in a mold (mold for sealing member molding) for injection molding the sealing member 120. The molding material of the member 120 is injected into a sealing member molding die and solidified, and the sealing member 120 is injection molded. Thereby, as shown in FIG. 9, the front-end | tip part of the connection sheet 130 can be integrated with the sealing member 120. FIG. Subsequently, the cover body 110 is molded in a state where the connection sheet 130 in which the sealing member 120 is integrated is disposed at a predetermined position in a mold (cover body molding mold) for injection molding the cover body 110. The material is poured into a cover body molding die and solidified, and the cover body 110 is injection molded. As a result, as shown in FIG. 10, the base end portion of the connection sheet 130 can be integrated with the cover body 110, and the housing fixing portion 130 b at the distal end portion of the connection sheet 130 can be integrated with the cover body 110. . Finally, the after-fitting fixing part 134 is attached to the after-fitting fixing part attachment hole 133 in the connection sheet 130, and the manufacture of the protective cover 100 for gaming machines is completed.

  However, the housing fixing portion 130b at the distal end portion of the connecting sheet 130 is not fixed in a state of being embedded in the cover main body 110, but the housing fixing portion 130b is engaged with a predetermined portion of the cover main body 110, etc. When adopting a structure in which the housing fixing portion 130b can be fixed to the cover body 110 even after the injection molding of the main body 110 is completed, the order of performing the injection molding of the sealing member 120 and the injection molding of the cover main body 110 is changed. It may be reversed. Further, the fixing part 134 after fitting may be attached in advance to the connecting sheet 130 before the sealing member 120 is injection-molded or before the cover main body 110 is injection-molded, or the sealing member 120 or the cover main body 110 is fixed. The injection molding may be performed simultaneously with the sealing member 120 and the cover main body 110 when performing the injection molding.

4). How to use the protective cover for gaming machines As shown in FIGS. 4 and 5, the protective cover 100 for gaming machines of the present embodiment described above has the sealing member 120 accommodated in the sealing member accommodating portion 112 in the cover main body 110. Can be transported, stored, attached, etc. For this reason, when carrying the protective cover 100 for gaming machines, the sealing member 120 collides with the cover main body 110 etc., and the sealing member 120 and the cover main body 110 are hard to be damaged. Therefore, despite the fact that fraudulent acts have not been performed, it is not mistaken for fraudulent acts due to the damage marks.

  Moreover, the protective cover 100 for gaming machines according to this embodiment can be suitably used as the cover 30d of the control board unit 30 (see FIG. 3) in the rotating type gaming machine as already described. The protective cover 100 for gaming machines according to this embodiment is disposed at a target mounting location (a predetermined location on the holder 30c of the control board unit 30) and is located at the back A of the sealing target hole 111 (see FIG. 4). After screwing or the like, the pair of housing fixing portions 130b of the connecting sheet 130 are cut with a scissors or the like, the tip of the connecting sheet 120 is separated from the cover body 110, and the sealing member 120 is fitted into the sealing target hole 111. In this way, the inner part A of the sealing target hole 111 can be sealed.

  When moving the sealing member 120 from the sealing member accommodating portion 112 to the sealing target hole 111, care is taken so that the connecting sheet 130 is not twisted. Specifically, the sealing member 120 is lifted from the position shown in FIG. 4 to the front side of the drawing, and moved to the sealing target hole 111 so as to be rotated 180 ° about an axis parallel to the x-axis direction. When the sealing member 120 is pushed into the sealing target hole 111 in this state, the engaging portion 121a of the sealing member 120 and the engaged portion 111a of the sealing target hole 111 are engaged as shown in FIG. Cannot be easily pulled out of the sealing target hole 111. Moreover, it is located above the engaging portion 121a and the engaged portion 111a (the negative side in the y-axis direction in FIG. 12) in the gap (insertion gap) between the outer peripheral surface of the sealing member 120 and the inner peripheral surface of the sealing target hole 111. The part to be covered is covered with the connecting sheet 130. At this time, the fixed portion 134 after fitting of the connecting sheet 130 is fixed to the fixed portion 113 after fitting of the cover main body 110, and a portion of the connecting sheet 130 located around the sealing target hole 111 does not float from the cover main body 110. Like that.

  When the sealing target hole 111 is sealed by the above procedure, the following advantages are obtained. That is, in order to perform an illegal act, even if the sealing member 120 is pulled out of the sealing target hole 111 and the screw at the back part A of the sealing target hole 111 is to be removed, the engaging part 121a and the engaged part 111a are Since it is engaged, the sealing member 120 cannot be pulled out. Further, at this time, even if an unauthorized insertion tool such as a flat-blade screwdriver is inserted into the above-mentioned fitting gap to try to release the engagement between the engaging portion 121a and the engaged portion 111a, the engaging portion 121a in the fitting gap. Since the portion located above the engaged portion 111a is covered with the connecting sheet 130, the engaging portion 121a and the engaged portion 111a are not left on the connecting sheet 130 without leaving any trace of fraud. It is difficult to release the engagement.

  Furthermore, in the protective cover 100 for gaming machines of this embodiment, in addition to the cover main body 110 and the sealing member 120 being connected to each other via the connecting sheet 130, the base end portion and the distal end portion of the connecting sheet 130 Are fixed in a state of being embedded in the cover main body 110 and the sealing member 120, respectively. For this reason, in the case of improper acts, when the seal member 120 or the connection sheet 130 is formed with a trace, the seal member 120 or the connection sheet 130 is replaced with a counterfeit product even if an attempt is made to replace the member with a counterfeit product. It is not possible to erase the traces of fraud alone, and some traces remain.

  For example, if only the sealing member 120 is to be replaced with a counterfeit product, it is necessary to remove the sealing member 120 from the connection sheet 130. However, since the leading end portion of the connecting sheet 130 is fixed in a state of being embedded in the sealing member 120, the sealing member 120 can be removed from the connecting sheet 130 unless the connecting sheet 130 is broken in the vicinity of the leading end portion. I can't do it. In this case, a breakage mark or the like of the connection sheet 130 is recognized as a trace of fraud. In other words, in the gaming machine protective cover 100 of this embodiment, it is impossible to replace only the sealing member 120 with a counterfeit product in a state where the traces of fraud are completely erased. In the protective cover 100 for gaming machines of this embodiment, if the sealing member 120 is replaced with a counterfeit product, the connecting sheet 130 must also be replaced with a counterfeit product.

  However, if both the sealing member 120 and the connection sheet 130 are to be replaced with counterfeit products, the connection sheet 130 needs to be removed from the cover body 110. However, since the base end portion of the connection sheet 130 is fixed while being embedded in the cover main body 110, the connection sheet 130 is broken near the base end portion, or the connection sheet 130 at the front end portion of the cover main body 110. The connection sheet 130 cannot be removed from the cover body 110 unless the vicinity of the portion embedded in the cover is destroyed. In this case, a breakage mark of the connection sheet 130, a breakage mark of the cover body 110, and the like are recognized as a trace of fraud. That is, in the gaming machine protective cover 100 of this embodiment, it is impossible to replace only the sealing member 120 and the connecting sheet 130 with counterfeit products in a state in which the traces of fraud are completely erased. In the protective cover 100 for gaming machines of this embodiment, if the sealing member 120 and the connecting sheet 130 are replaced with counterfeit products, the cover main body 110 also needs to be replaced with counterfeit products.

  As described above, in the protective cover 110 for gaming machines of the present embodiment, any one or two of the sealing member 120, the connecting sheet 130, and the cover main body 110 are used to completely erase the trace of fraud. It is not necessary to replace only the counterfeit product with a counterfeit product, and it is necessary to replace all of them with counterfeit products. Therefore, the protection cover 100 for gaming machines according to this embodiment is very difficult to cheat and has a high deterrent effect.
