Description

The present invention relates to a gaming machine .

Conventionally, a gaming machine of a slot machine has a gaming device necessary for playing a game, a control board on which a control circuit for controlling the operation of the gaming device is formed, and a power supply device that supplies power to the gaming device and the control board Etc. are provided.
Among these, the control board includes a ROM that stores a program for controlling a game operation, and a CPU that includes an LSI having a high-speed calculation function, and the CPU stores the program stored in the ROM.
Such a control board is a transparent synthetic resin board case formed in a box shape to prevent illegal acts such as replacing the genuine ROM with an unauthorized ROM storing an unauthorized program that is easy to win. It is stored inside.

The substrate case for storing the control board has a box shape with one side opened, and a base part on which the control board is installed, and a cover part that covers the upper side of the control board installed on the base part. What is provided is common.
And these base parts and a cover part are couple | bonded together in the closed state, in order to protect the control board installed in the inside from an unauthorized act.

Here, the board case is generally formed with a screw insertion hole in the lid portion through which a screw for joining the lid portion and the base portion to each other is inserted. Then, a screw is inserted into a screw insertion hole formed in the lid, and the tip of the screw is screwed to the base so that the lid and the base are joined to each other.
Further, a sealing cap for sealing the insertion hole is fitted into the screw insertion hole. Once this sealing cap is fitted into the screw insertion hole, it cannot be removed from the lid unless the lid or the sealing cap is destroyed.

Therefore, after the lid portion and the base portion are joined to each other with the screws inserted into the screw insertion holes, the sealing cap is fitted into the screw insertion holes, and the screws inserted into the screw insertion holes are sealed with the sealing cap. If the lid or the sealing cap is not destroyed, the sealing cap cannot be removed from the lid, and consequently the substrate case cannot be opened.
In other words, the lid part is joined to the base part with screws, and the board case is closed by sealing the screw inserted through the screw insertion hole with the sealing cap, and then opening the board case, the lid part and the sealing part are sealed. Since at least one of the stop caps is destroyed and the trace remains on the lid or the sealing cap, when the substrate case is opened to illegally replace the ROM of the control board, the substrate case is not attached to the lid or the sealing cap. An open trace remains, and this trace makes it possible to clearly determine that an illegal act has been performed, thereby preventing an illegal act on the control board such as an illegal replacement of the ROM (for example, Patent Document 1).

JP 2007-312916 A

The sealing cap (70) is formed of a transparent synthetic resin and has a locking structure for locking to at least one of the first member (52) or the second member (53). And a cap-shaped lid portion (72) that closes one end of the tube portion (71). The cap-shaped lid portion (72) is configured to transmit laser light having a predetermined wavelength. Concave and convex shape of 3D curved surface that is marked by irradiation is shaped The first resin portion (75) thus formed is not overlapped with a laser beam having a predetermined wavelength, and the second resin portion is arranged so as to cover the marking applied to the first resin portion (75). And a resin portion (76) .

(Effect of Claim 1)
The present invention configured as described above has the following effects.
That is, according to the first aspect of the present invention, an identification mark set in advance by irradiation with a laser beam having a predetermined wavelength can be marked on the boundary surface between the first resin portion and the second resin portion. Once you have marked a different identification mark for each in the sealing cap, using the sealing cap has been removed from another gaming machine, the difference of the identification mark, use of the sealing cap is removed from another gaming machine Easy and clear discrimination.
Here, the identification mark is marked on the sealing cap has been removed from another gaming machine, in order to match the game machine to be cheating, it is conceivable to tamper with the identification mark, the first resin Since the identification mark is marked on the boundary surface between the first resin portion and the second resin portion , the identification mark cannot be falsified even if the surface of the sealing cap is shaved, and the sealing cap is removed from another gaming machine The identification mark cannot be matched with the gaming machine subject to the fraud.
Moreover, since the unevenness of the three-dimensional curved surface is formed on the boundary surface between the first resin portion and the second resin portion, it becomes very difficult to peel the first resin portion from the second resin portion, and it is formed on the boundary surface. It is also very difficult to tamper with the identification mark. On the other hand, when the boundary surface between the first resin portion and the second resin portion is a flat surface, the first resin portion may be neatly peeled from the second resin portion by skillfully manipulating a sharp blade such as a cutter. If the first resin portion can be cleanly separated from the second resin portion, the identification mark can be falsified by scraping off the identification mark formed on the boundary surface and entering another identification mark. However, as described above, since the unevenness of the three-dimensional curved surface is formed on the boundary surface, the first resin part cannot be peeled cleanly from the second resin part, and the identification mark cannot be falsified. However, it is possible to make it difficult to make a so-called “seal” that is mistaken for a real sealing cap.

In addition, the boundary surface 75A of the first resin portion 75 that is in contact with the second resin portion 76. In other words, the boundary surface 75A of the additive-added layer 72A that is in contact with the additive-non-added layer 72B A preset identification mark is marked by irradiation with laser light having a predetermined wavelength that has passed through 72B.

As shown in FIGS. 10 to 12, the first resin portion 75 is a portion including a substantially hexagonal tubular portion 71 and a non-additive layer 72 </ b> B formed in a disc shape.
At this time, the boundary surface 75A of the first resin portion 75 is provided with a bulging portion 75B bulging toward the second resin portion 76 at the center as shown in FIGS. Further, a corrugated portion 75C in which corrugated irregularities are formed is provided at the peripheral portion of the boundary surface 75A.

As shown in FIGS. 10 to 12, the second resin portion 76 is a portion composed of only the non-additive layer 72B formed in a disk shape.
As shown in FIG. 12, the left side surface of the second resin portion 76 in FIG. 12 is a dome-shaped surface 76A that bulges to the left side in the drawing, that is, to the outside.
Further, on the surface of the second resin portion 76 facing the first resin portion 75 side, a recess 76B capable of accommodating the additive addition layer 72A on the first resin portion 75 side is formed.
The bottom surface 76C of the recess 76B formed in the second resin portion 76 has a form corresponding to the boundary surface 75A of the first resin portion 75.
That is, as shown in FIGS. 11 and 12, the bottom surface 76C of the second resin portion 76 is provided with a recessed portion 76D that is recessed corresponding to the bulging portion 75B of the first resin portion 75 at the center thereof. Further, a corrugated portion 76E in which corrugated irregularities corresponding to the corrugated portion 75C on the first resin portion 75 side is formed at the peripheral portion of the hollow portion 76D.

Here, in the sealing cap 70, the boundary surfaces (the boundary surface 75A and the bottom surface 76C) of the first resin portion 75 and the second resin portion 76 are not flat surfaces, but are uneven surfaces corresponding to each other. The first resin portion 75 and the second resin portion 76 are integrated with each other.
As a result, even if a sharp blade such as a cutter is skillfully manipulated, the first resin part 75 and the second resin part 76 cannot be separated cleanly. As a result, the additive-added layer 72A is cleaned from the additive-free layer 72B. It is also impossible to peel off.

Returning to FIG. 8, the sealing cap 70 passes through the non-additive layer 72B at the boundary surface 75A of the additive-added layer 72A in contact with the non-additive-added layer 72B, as shown in FIG. By irradiating a laser beam L (laser light) of a predetermined wavelength, a preset identification mark 77 (“AKC47” in FIG. 8) is marked on the boundary surface 75A. The marked identification mark 77 is formed across both the punch-out portion 73 and the non-punch-out portion 74. The identification mark 77 has a different form for each model of the slot machine 1.
In FIG. 8, the identification mark 77 is expressed in a form written on a plane for the convenience of drawing, but is actually marked on a distorted form because it is written on a three-dimensional curved surface. It is like that.

In the above, the main board case 50 has the main control board 15 accommodated therein, the lid part 53 is joined to the base part 52 with the screw 60, and the concave part 53C into which the screw 60 is inserted is provided. The identification mark 77 is sealed with a marked sealing cap 70.
When the concave portion 53C is sealed by the sealing cap 70, the main substrate case 50 has a dome-shaped surface 76A, which is the surface of the cap-shaped lid portion 72 of the sealing cap 70, and a concave portion as shown in FIG. An associated marking group 55 ("AKC47" in FIG. 13) that associates the sealing cap 70 and the main body 51 with each other is formed across the surface 56 of the front portion 53A of the main body 51 that surrounds 53C. It has become.

At this time, the associated marking group 55 is laser-engraved with a laser beam having a predetermined wavelength (for example, a CO ₂ laser beam) different from the laser beam having a predetermined wavelength (for example, a YAG laser or a YVO ₄ laser beam). It is marked by.
The associated marking group 55 is composed of characters, symbols, figures, patterns, or a combination thereof, and has a single meaning as a whole, so that it has a different form from the other main board case 50. The dome-shaped surface 76A of the lid portion 72 and the surface 56 of the main body 51 are stamped. In other words, the associated marking group 55 associates the sealing cap 70 and the main body 51 belonging to the same main substrate case 50 on a one-to-one basis.
In FIG. 13, “AKC47”, which is a serial number that identifies the slot machine 1 and includes alphabets and numbers, is employed as the associated marking group 55.
As a result, even if the original sealing cap 70 is removed from the main board case 50 and the non-original sealing cap 70 removed from the other main board case 50 is fitted into the recess 53C, Since the associated marking group 55 engraved on 51 and the associated marking group 55 made on the non-original sealing cap 70 do not match, the use of the sealing cap 70 removed from another main board case 50 is not possible. It can be easily and clearly discriminated.

(Sub-board case 2D)
Next, the sub board case 2D containing the sub control board 16 will be briefly described.
As shown in FIG. 14, the sub-board case 2D has a box-shaped main body portion 91 for accommodating therein the sub-control board 16 on which a control circuit for controlling the gaming operation of the slot machine 1 is formed. I have.
The main body 91 is a member made of a transparent synthetic resin that can be visually recognized from the outside. The main body portion 91 includes a flat base portion 92 to which the sub-control board 16 is attached, and a box-like lid portion 93 having an opening facing the sub-control board 16 attached to the base portion 92. Is provided.
In such a main body 91, the lid portion 93 is applied to the base portion 92 so as to cover almost the entire surface of the base portion 92 to which the sub-control board 16 is attached. The base portion 92 is joined to each other.

Here, in the four corners 97A to 97D of the front part 93A of the lid part 93 formed in a substantially rectangular shape, recesses 53C similar to those formed in the main board case 50 are respectively provided.
Then, although not particularly shown, a screw 60 and a sealing cap 70 similar to those used for joining the main substrate case 50 are inserted into the recess 53C. Among these, the lid portion 93 and the base portion 92 are joined to each other by the screw 60, and the head portion of the screw 60 that joins the lid portion 93 and the base portion 92 is sealed by the sealing cap 70. It has become.

In such a sub-board case 2D, when the concave portion 53C is sealed with the sealing cap 70, the surface of the cap-shaped lid portion 72 of the sealing cap 70 and the front portion of the main body 91 surrounding the concave portion 53C. The associated mark 20 that correlates the sealing cap 70 and the main body 51 to each other is engraved across the surface 96 of 93A.
Here, of the associated marks 20, the associated mark 20A is engraved in the upper left corner portion 97A in FIG. 14 on the front surface 93A of the lid 93, and the associated mark 20B is the front portion of the lid 93. In FIG. 14 at 93A, the upper right corner portion 97B is engraved, and the associated mark 20C is engraved at the lower left corner portion 97C in FIG. 14 at the front portion 93A of the lid portion 93, and the associated mark 20D is In the front portion 93A of the lid portion 93, the lower right corner portion 97C is stamped in FIG.

Each of the associated marks 20 is stamped with a laser beam of a predetermined wavelength (for example, CO ₂ laser light), similarly to the associated marking group 55B formed on the main substrate case 50.
More specifically, the associated mark 20 is a circular mark having a diameter similar to that of the cap-shaped lid portion 72 provided on the sealing cap 70.
As shown in FIGS. 15A to 15D, each of the associated marks 20 has four fan-shaped first to fourth character frame portions 21 to 24 having a central angle set to 90 degrees. And a circular position display unit 25 disposed in the central portion. The associated mark 20 has a model name “Twin 3” from the first character frame portion 21 to the fourth character frame portion 24.

The first character frame portion 21 is a portion located at the upper right in FIG. 15 in the associated mark 20, and in FIG. 15, the character of “tsu” is white on the hatched ground consisting of a number of straight lines extending in the horizontal direction. It has been removed.
The second character frame portion 22 is a portion located at the lower right in FIG. 15 in the associated mark 20. In FIG. 15, the character “I” is displayed on the hatched ground consisting of a number of straight lines extending upward. It is outlined.
The third character frame portion 23 is a portion of the associated mark 20 located at the lower left in FIG. 15. In FIG. 15, the character “n” is outlined on the hatched ground consisting of a number of straight lines extending vertically. It has been done.
The fourth character frame portion 24 is a portion located at the upper left in FIG. 15 in the associated mark 20, and in FIG. 15, the character “3” is white on the hatched ground consisting of a number of straight lines extending downward to the right. It has been removed.

In the position display portions 25 of the associated marks 20A to 20D, characters corresponding to the positions to be stamped on the front portion 93A of the lid portion 93 are written.
In other words, the position display portion 25A of the associated mark 20A is marked with a character “1” indicating that the corner portion 97A of the front portion 93A of the lid portion 93 is imprinted.
On the position display portion 25B of the associated mark 20B, characters “2” indicating that the corner portion 97B of the front portion 93A of the lid portion 93 is imprinted are marked.
On the position display portion 25C of the associated mark 20C, a character “3” is written indicating that the corner portion 97C of the front portion 93A of the lid portion 93 is imprinted.
On the position display portion 25D of the associated mark 20D, characters “4” indicating that the corner portion 97D is engraved on the front portion 93A of the lid portion 93 are marked.

The associated mark 20 as described above has a quotient value obtained by dividing 360 ° by an integer equal to or greater than 2 with the peripheral portion centered on the center point of the associated mark 20 formed in a circle. Even if it is rotated by an angle, it has a rotationally asymmetric shape that does not overlap with its own shape before rotation.
Then, the concave portion 53C of the sub-board case 2D installed in the other slot machine 1 is sealed in the cap-shaped lid portion 72 of the sealing cap 70 that seals the concave portion 53C of the sub-board case 2D. A portion of the associated mark 20 having a different rotational angle position is engraved on the cap-shaped lid portion 72 of the sealing cap 70.

In other words, the associating mark 20 is formed in a flow operation one after the other sub-board case 2D, and when the marking of the associating mark 20 is completed for one sub-board case 2D, the next sub-board case The case 2D is engraved so that its rotational angle position is rotated by a predetermined angle (for example, 90 degrees).
In the following, associating marks 20A engraved on the cap-shaped lid portion 72 of the sealing cap 70 fitted in the recesses 53C formed in the corners 97A of the sub-board case 2D will be described as an example. Will be described in detail.

  That is, as shown in FIG. 16A, the corner portion 97A of the sub-board case 2D shown in FIG. 4 has an associated mark 20A on the top in FIG. The associated mark 20A is engraved so that the center point is arranged. As a result, the cap-shaped lid portion 72 of the sealing cap 70 fitted in the concave portion of the corner portion 97A of the sub-board case 2D has a first character frame portion 21 of the associated mark 20A as shown in FIG. And the 4th character frame part 24 is engraved.

  Next to the sub-board case 2D shown in FIG. 16 (A), the corner portion 97A of the sub-board case 2D on which the associated mark 20A is engraved is formed as shown in FIG. 16 (B). In FIG. 16 (B) of the portion 72, the center point of the associated mark 20A is arranged at the top portion, and the associated angle 20A shown in FIG. 16 (A) is 90 degrees clockwise. The rotated association mark 20A is engraved. Accordingly, the fourth character frame portion 24 and the third character frame portion 23 of the associated mark 20A are engraved on the cap-shaped lid portion 72 of the sealing cap 70 as shown in FIG.

  Next to the sub-board case 2D shown in FIG. 16 (B), the corner portion 97A of the sub-board case 2D on which the associated mark 20A is engraved, as shown in FIG. In FIG. 16C of 72, the center point of the associated mark 20A is arranged at the top portion, and the rotational angle position of the associated mark 20A shown in FIG. 16B is rotated 90 degrees clockwise. The associated mark 20A is engraved. Accordingly, the third character frame portion 23 and the second character frame portion 22 of the associated mark 20A are engraved on the cap-shaped lid portion 72 of the sealing cap 70 as shown in FIG.

  Next to the sub-board case 2D shown in FIG. 16 (C), the corner portion 97A of the sub-board case 2D on which the associated mark 20A is engraved is shown in FIG. 16 (D). In FIG. 16D of 72, the center point of the associated mark 20A is arranged at the top portion, and the rotational angle position of the associated mark 20A shown in FIG. 16C is rotated 90 degrees clockwise. The associated mark 20A is engraved. Thus, the second character frame portion 22 and the first character frame portion 21 of the associated mark 20A are engraved on the cap-shaped lid portion 72 of the sealing cap 70 as shown in FIG.

In the above, the associated mark 20 is engraved on the sub-board case 2D fitted with the cap-shaped lid portion 72 of the sealing cap 70 by the laser engraving work continuously performed on the plurality of sub-board cases 2D. When the associated mark 20 is stamped, the associated mark 20 having a different rotational angle position by a predetermined angle from the previous stamping operation is stamped. Accordingly, the cap-shaped lid portion 72 of the sealing cap 70 included in one slot machine 1 is different from the cap-shaped cap portion 72 of the sealing cap 70 included in the other slot machine 1 in relation to the rotation angle of the associated mark 20. Sites with different positions are formed.
Accordingly, the portion of the associated mark 20 formed on the cap-shaped lid portion 72 is different for each slot machine 1 even if it is the same model.
If the number of sub-board cases 2D manufactured is large, when the next associated mark 20 is engraved, the rotation angle position of the associated mark 20 is rotated by a smaller angle, It is preferable to increase the variation of the portion of the associated mark 20 formed on the cap-shaped lid portion 72. Further, by increasing the number of types of the associated mark 20 itself, the type of the associated mark 20 and the cap-shaped lid portion 72 are increased. You may increase the variation of the part of the associated mark 20 formed.

(Effect of 1st Embodiment)
According to this embodiment as described above, the following effects can be obtained.
That is, the additive that absorbs the irradiated laser beam of a predetermined wavelength and changes the surrounding synthetic resin to be opaque to the lid portion 53 of the sealing cap 70 that seals the concave portion 53C through which the screw 60 is inserted. The additive-added layer 72A, which can be marked by irradiation with laser light of a predetermined wavelength, is formed as a layer that overlaps the additive-added layer 72A, and the additive-added layer 72A is not added. An additive-free layer 72B that is not marked by irradiation with laser light of a wavelength is provided, and an additive-free layer 72B is added to the boundary surface 75A of the additive-added layer 72A that is in contact with the additive-free layer 72B. The identification mark 77 set in advance can be marked by irradiation with laser light having a predetermined wavelength that has passed through, and the identification mark 77 is provided on the boundary surface 75A between the additive-added layer 72A and the non-additive layer 72B. If you mark it Even if the sealing cap 70 is duplicated by taking the mold of the sealing cap 70 with silicone rubber or the like for molding, it is marked on the boundary surface 75A between the additive-added layer 72A and the non-additive layer 72B. The identification mark 77 cannot be duplicated, and as a result, it is impossible to produce a product that is mistaken for the real product.

Even if the sealing cap 70 can be stolen from another slot machine 1, the serial number or the like that differs for each slot machine 1 is used as the identification mark 77, and if this identification mark 77 is marked on the sealing cap 70, the sealing cap 70 is sealed. Even if the surface of the stop cap 70 is shaved, the identification mark 77 cannot be falsified, and also from this point, it becomes impossible to produce the sealing cap 70 for the container.
Here, it is conceivable to manufacture the sealing cap 70 of the porridge in the same process as the real product, but the sealing cap 70 having the lid portion 53 in which the additive-added layer 72A and the additive non-added layer 72B overlap each other. The marking of the identification mark 77 by molding or laser irradiation on the boundary surface 75A of the additive-added layer 72A and the non-additive-added layer 72B cannot be easily realized because the cost of the processing equipment is expensive. Therefore, it is possible to make it difficult to make a product that is mistaken for a real sealing cap 70, and to effectively prevent fraud.

  Further, since the identification mark 77 different for each model of the slot machine 1 is marked on the sealing cap, even if an attempt is made to use the sealing cap 70 removed from the slot machine 1 of a different model, the difference in the identification mark 77 is caused. It can be easily and clearly determined that the sealing cap 70 removed from another model is used.

  Here, in order to align the identification mark 77 marked on the sealing cap 70 removed from another model with the gaming machine subject to fraud, it is conceivable to tamper with the identification mark 77. Since the identification mark 77 is marked on the boundary surface 75A between the additive-added layer 72A and the non-additive layer 72B, the identification mark 77 cannot be falsified even if the surface of the sealing cap 70 is shaved. The identification mark 77 of the sealing cap 70 removed from the model cannot be aligned with the slot machine 1 that is the target of fraud, and this can effectively prevent fraud.

In addition, both of the surface of the cap-shaped lid portion 72 of the sealing cap 70 that seals the recess 53C and the surface 96 of the front portion 93A of the main body 91 surrounding the periphery of the recess 53C in the sub-board case 2D are provided. Then, an association mark 20 as an index for associating the sealing cap 70 and the sub-board case 2D with each other is engraved, the association mark 20 is a predetermined rotationally asymmetrical mark, and the recess 53C is further formed. When marking the associated mark 20 on the shade-shaped lid portion 72 of the sealing cap 70 that is sealed, the rotational angle position of the associated mark 20 is different from the shade-shaped lid portion 72 of other slot machines 1. Since the portion thus formed is engraved on the cap-shaped lid portion 72, the portion of the associated mark 20 formed on the cap-shaped lid portion 72 is different for each slot machine 1 even in the same model.
Therefore, when the concave portion 53C is sealed with the sealing cap 70 removed from another slot machine 1, the associated mark 20 formed on the cap-shaped lid portion 72 of the sealing cap 70 removed from the other slot machine 1 is displayed. Since the part does not match the part of the associated mark 20 stamped on the sub-board case 2D of the slot machine 1, from this point, even if it is the same model, the seal removed from another slot machine 1 is used. The use of the stop cap 70 can be easily and clearly discriminated, and therefore the prevention of fraud can be effectively performed.

Further, since the punch-out portion 73 that can be easily punched is provided in the lid portion 53, when the screw 60 inserted into the concave portion 53C is loosened in order to open the closed main board case 50, the punch-out portion 73 is punched out. If a hole is formed in the portion 73, the hole can be easily drilled, and the screw 60 can be easily loosened through the hole thus opened, whereby the main board case 50 can be easily opened.
Here, since punching to the punch-out part 73 can be easily performed, the punching work when the main board case 50 is illegally opened can be easily performed, but the non-punch-out part is difficult to punch. 73 and the punch-out portion 73 that can be easily punched, the identification mark 77 is formed. Therefore, a saddle member having the same shape is made of the same material as the punch-out portion 73, and Even though the formed hole is closed, the additive-added layer 72A and the additive-free layer 72B are not formed on the eaves member that closes the hole, and the genuine identification mark 77 is added to the additive-added layer 72A. Since the marking is made on the boundary surface 75A with the non-agent-added layer 72B, a part of the identification mark 77 formed on the boundary surface 75A of the punch-out portion 73 is placed inside the saddle member in the same manner as the genuine identification mark 77. It becomes impossible to mark on.
Therefore, even if the punch-out portion 73 of the real sealing cap 70 is replaced with another member, it is not mistaken for the real sealing cap 70, and from this point as well, it can be mistaken for the real sealing cap 70. It is possible to make it difficult.

Further, since the corrugated irregularities are formed on the boundary surface 75A between the additive-added layer 72A and the non-additive layer 72B, it becomes very difficult to peel the additive-added layer 72A from the non-additive-added layer 72B. It is very difficult to falsify the identification mark 77 formed on the boundary surface 75A.
On the other hand, when the boundary surface 75A between the additive-added layer 72A and the non-additive-added layer 72B is a flat surface, the additive-added layer 72A is made non-additive-added layer by skillfully manipulating a sharp blade such as a cutter. If the additive-added layer 72A can be peeled cleanly from the non-additive layer 72B, the identification mark 77 formed on the boundary surface 75A is scraped off and another identification mark 77 is written. Thus, the identification mark 77 can be falsified.
However, as described above, since the corrugated irregularities are formed on the boundary surface 75A, the additive-added layer 72A cannot be removed cleanly from the additive-free layer 72B, and the identification mark 77 cannot be falsified. Also in this respect, it is possible to make it difficult to make a so-called “seal” that is mistaken for the real sealing cap 70.

In addition, because the management plate 80 is added with an additive that absorbs laser light and changes the surrounding synthetic resin to be opaque, the management of the blank state where no management information such as serial number is described After the plate 80 and the main control board 15 are put into the main body 51 of the main board case 50, the main board case 50 can be closed by joining the base part 52 and the lid part 53 to each other and closing the main board case 50. In this state, the control device configured by the above-mentioned control device is in a completed state, and in this state, a product inspection is performed. When irradiated, the management information and the like can be marked on the management plate 80 without opening the main board case 50.
For this reason, even if the main board case 50 is closed with the management plate 80 stored inside, the management plate 80 can be marked with laser light from the outside of the main board case 50. There is no need to provide a separate cover, and after the main board case 50 is closed, there is no need to attach the cover that covers the management plate 80 to the main board case 50, and the management plate 80 and the main control board 15 are installed inside. By closing the main board case 50 in the state of being housed in the housing, it is possible to obtain a completed state that requires no further assembly work.
In addition, in this completed state, the screw 60 that joins the main substrate case 50 is sealed by the sealing cap 70, and then the sealing cap 70 needs to be destroyed to open the main substrate case 50. For this reason, when the main board case 50 is opened after closing, the sealing cap 70 is broken, so that the opening of the main board case 50 can be easily discriminated, and thus the security function can be sufficiently secured.

  Further, a first vent 53P is provided in the main body 51 so as to penetrate the portion of the main body 51 where the management plate 80 is attached and communicates the inside and the outside of the main body 51, and the management plate 80 includes the management plate 80. The second vent 82 is formed so as to pass through 80 and be attached to the main body 51 so as to be displaced from the first vent 53P, and each of the main body 51 and the management plate 80 has a main body. Since the first ventilation recess 53R and the second ventilation recess 84 that connect the second ventilation hole 82 of the management plate 80 attached to the part 51 and the first ventilation hole 53P on the body part 51 side are formed, When the management plate 80 is fixed, the inside and the outside of the main body 51 are communicated with each other, and an air passage 85 bent in a crank shape is formed. The air in the main board case 50 is ventilated by the air passage 85 bent in the crank shape, and the main control board 15 that generates heat can be cooled, and the air passage 85 is bent in the crank shape. Even if it is inserted into the first vent 53P, the tip of the elongated tool does not reach the inside of the main board case 50. From this point, the security function can be performed without increasing the work related to the management plate 80. Can be secured sufficiently.

  Furthermore, the sealing cap 70 and the main body portion are formed on the dome-shaped surface 76A of the cap-shaped lid portion 72 provided on the sealing cap 70 that seals the concave portion 53C and the surface 56 of the main body portion 51 surrounding the periphery of the concave portion 53C. Since the associated marking group 55 for associating 51 with each other is formed, sealing the recess 53C with the sealing cap 70 removed from the other main substrate case 50 separates the associated marking group 55 from the main body 51. Since the associated marking group 55 made on the sealing cap 70 removed from the main board case 50 of the main board case 50 does not match, therefore, the use of the sealing cap 70 removed from another main board case 50 can be easily and clearly distinguished. can do.

[Second Embodiment]
17 to 20 show a second embodiment of the present invention.
In the following description, the same reference numerals are assigned to the same devices and parts as those in the first embodiment, and the description thereof is omitted or simplified.
In the second embodiment, the associated marking group 55 formed over both the surface of the sealing cap 70 and the surface of the main substrate case 50 in the first embodiment is changed to a boundary surface 75A of the sealing cap 70 and An associated marking group 55B formed over both surfaces of the main board case 50, and an associated mark 20 formed over both the surface of the sealing cap 70 and the surface of the sub board case 2D, The associated marking group 55C is formed across both the boundary surface 75A of the sealing cap 70 and the surface of the sub-board case 2D.

That is, as shown in FIG. 17, the sealing cap 70 is not marked on the boundary surface 75A before being fitted into the recess 53C of the main substrate case 50.
On the other hand, the main substrate case 50 absorbs laser light of a predetermined wavelength (for example, light of YAG laser or YVO ₄ laser) in at least the transparent synthetic resin forming the lid portion 53 of the base portion 52 and the lid portion 53. Thus, an additive for changing the surrounding synthetic resin to black (opaque) is added. Thereby, at least the surface of the lid 53 can be marked with black by irradiation with laser light of a predetermined wavelength.

  When the concave portion 53C is sealed with the sealing cap 70, the main substrate case 50 has a boundary surface 75A of the cap-shaped lid portion 72 of the sealing cap 70 and the periphery of the concave portion 53C as shown in FIG. An associated marking group 55B ("AKC47" in FIG. 18) for associating the sealing cap 70 and the main body 51 with each other is formed across the surface 56 of the front portion 53A of the main body 51 surrounding the main body 51. .

At this time, the associated marking group 55B is marked with the above-described laser light with a predetermined wavelength (for example, YAG laser or YVO ₄ laser light).
The associated marking group 55B is composed of characters, symbols, figures, patterns, or combinations thereof, and has a single meaning as a whole, and is a main board case provided in another slot machine 1 of the same model. The marking is performed across the boundary surface 75A of the cap-shaped lid portion 72 and the surface 56 of the main body portion 51 so as to be different from 50. In other words, the associated marking group 55B associates the sealing cap 70 and the main body 51 belonging to the same main board case 50 on a one-to-one basis.
More specifically, as the associated marking group 55B, as shown in FIG. 18, “AKC47”, which is a serial number for identifying the slot machine 1 and includes alphabets and numbers, is employed.
As a result, even if the original sealing cap 70 is removed from the main board case 50 and the non-original sealing cap 70 removed from the other main board case 50 is fitted into the recess 53C, Since the associated marking group 55B engraved on 51 and the associated marking group 55B made on the non-original sealing cap 70 do not match, the use of the sealing cap 70 removed from another main board case 50 is not possible. It can be easily and clearly discriminated.

The associated marking group 55B includes a cap side portion 57 marked on the sealing cap 70 side and a case side portion 58 marked on the main body portion 51 side. Of these, the cap side portion 57 is sealed. This is an identification mark for the cap 70.
As a result, the process of marking the associated marking group 55B and the process of marking the identification mark (cap side portion 57) can be performed in a single laser marking process, and the production work of the main board case 50 can be made more efficient. It is possible.

The sub-board case 2D absorbs laser light of a predetermined wavelength (for example, YAG laser or YVO ₄ laser light) into at least the transparent synthetic resin that forms the lid portion 93 out of the base portion 92 and the lid portion 93. An additive that changes the surrounding synthetic resin to black (opaque) is added. As a result, at least the surface of the lid 93 can be marked black by irradiation with laser light having a predetermined wavelength.

  When the concave portion 53C is sealed with the sealing cap 70, the sub-board case 2D has a boundary surface 75A of the cap-shaped lid portion 72 of the sealing cap 70 and the concave portion as shown in FIGS. An associated marking group 55C for associating the sealing cap 70 and the main body 51 with each other is formed across the surface 96 of the front surface 93A of the main body 91 surrounding 53C.

At this time, the associated marking group 55C is marked with laser light of a predetermined wavelength (for example, YAG laser or YVO ₄ laser light) in the same manner as the associated marking group 55B formed on the main substrate case 50. .
The associated marking group 55C is composed of characters, symbols, figures, patterns, or combinations thereof, and has one meaning as a whole, and is different from the main board case 50 and the other sub board case 2D. Thus, marking is performed across the boundary surface 75A of the cap-shaped lid portion 72 and the surface 96 of the main body portion 91. In other words, the associated marking group 55C associates the sealing cap 70 and the main body 91 belonging to the same sub-board case 2D on a one-to-one basis.
More specifically, as the associated marking group 55C, as shown in FIG. 14, a serial number that identifies the slot machine 1 and "Tsunin 3" consisting of hiragana and numbers is adopted.
As a result, the original sealing cap 70 is removed from the sub board case 2D, and the non-original sealing cap 70 removed from the main board case 50 or another sub board case 2D is fitted into the recess 53C. However, since the associated marking group 55C engraved on the main body 91 and the associated marking group 55C formed on the non-original sealing cap 70 are not aligned, the main board case 50 or another sub-board case 2D The use of the sealing cap 70 that has been removed from can be easily and clearly discriminated.

As shown in FIG. 20, the associated marking group 55C includes a cap side portion 57A marked on the sealing cap 70 side and a case side portion 58B marked on the main body portion 91 side. The portion 57A serves as an identification mark for the sealing cap 70.
As a result, the process of marking the associated marking group 55C and the process of marking the identification mark (cap side portion 57A) can be performed in a single laser marking process, thereby improving the efficiency of the manufacturing work of the sub-board case 2D. It is possible.
