Description

  The present invention relates to a base case for a gaming machine for storing a control base for a gaming machine used in a gaming machine such as a pachinko machine or a slot machine.

Conventionally, as a base case for this type of gaming machine, a control base having a ROM or the like storing a program for controlling a game is fixed to the gaming machine in order to prevent damage caused by a collision of a pachinko ball or a medal. And a case cover that covers the case body.
In general, a gaming machine such as a pachinko machine or a slot machine is based on a control base having a ROM or the like that stores a program for controlling a game, and the probability of winning, the number of winning balls and payout medals. Game operations such as are controlled. The contents of the program stored in the ROM greatly influence the profit of the player and the profit of the game machine store. Therefore, the program stored in the ROM is one prepared by a gaming machine manufacturer so that the game content is such that the game content does not detract from the player's happiness.

  In addition, after installing a gaming machine at a gaming store, the legitimate ROM attached to the control board is illegally used in order to significantly increase the player's gambling with the gaming content that is significantly separated from the gaming content originally intended by the manufacturer. There is no end to fraudulent acts of replacing the ROM with a modified ROM. In order to prevent this illegal act, the case cover is fixed to the case body with screws so that the case cover is not opened unnecessarily, and it is also replaced with an illegally modified ROM that is indistinguishable from the regular ROM. In order not to be damaged, the case cover is opened by sticking a seal at a predetermined position between the case body and the case cover so that the fact that the case cover has been opened becomes clear at a glance. I was trying to understand the facts.

  However, in the above-mentioned conventional base case for gaming machines, the case cover is simply fixed to the case body by screwing, so remove the screw with a tool such as a screwdriver and skillfully remove the seal. After performing unauthorized modifications such as replacing the ROM, the case cover is still screwed and fixed, and the clever fraud is still performed, such as pasting the seal back. It was.

  In order to prevent this skillful fraud, once the case cover is closed, the case cover cannot be opened again unless the case is destroyed. However, in some cases, it is possible to inspect whether the control base of the gaming machine installed at the amusement store is legitimate or not in the state where it is installed at the amusement store. In this case, the base case is once destroyed. If it does so, after that, the base case could not be kept closed, and there was a problem that it would not be possible to effectively prevent subsequent unauthorized modification.

In addition, although a method of replacing the base case with a new one is also considered, there has been a problem that it is not practical because it takes too much time and cost when the inspection is performed a plurality of times.
Accordingly, the base case for a gaming machine according to claim 1 or 2 is made in view of the above-described problems of the prior art, and the object is to have a simple structure and the fixed portion. By preventing the base case from being removed from the gaming machine other than breaking the fractured part, it is possible to prevent unauthorized modification of the control base by making sure that the base case has been removed. In addition to providing a base case for gaming machines that can be easily detached from the base case for inspections, etc., and can be fixed to the gaming machine so that the base cannot be tampered with again. It is what.

(Feature point)
The present invention is for achieving the above-described object, and the contents thereof will be described below by using an example of the embodiment of the invention shown in the drawings.
In addition, although the code | symbol in parenthesis shows the code | symbol used in embodiment of invention, it does not limit the technical scope of this invention.
(Claim 1)
The base case for a gaming machine according to claim 1 is configured such that the case main body (20) is provided with a case cover (30) via a break portion (52) on the case main body (20) side protruding from the case main body (20). The case cover (30) can be fixed to each mounting portion (50) corresponding to each of the plurality of mounting portions (50), and The case cover (30) has a plurality of fixing portions (70) having a fracture portion (71) on the side of the case cover (30) protruding from the case cover (30), and the fixing portion (70) is a fixing for inserting a set screw (60). A cylinder having a hole (73), having an inner diameter slightly larger than the diameter of the head (61) of the set screw (60) around the fixing hole (73) and higher than the thickness of the head (61) And at least one of the fixing portions (70) is inserted into the mounting portion (50) corresponding to the fixing portion (70) and the fixing portion (70). Attached to the gaming machine via a set screw (60) The screw (60) is easily rotated in the screwing direction according to the twisting operation by the driver, and when the base case (10) is attached to the gaming machine board, the fixing part (70) that is not used for the attachment is next time. It can be used for subsequent fixing.

Therefore, according to the base case for gaming machines according to claim 1, with the control base housed in the case body (20), the set screw (60) is inserted into at least one fixing part (70), The base case (10) having the case main body (20) and the case cover (30) is fixed to the gaming machine by being fixed to the gaming machine via the mounting part (50) corresponding to the fixing part (70). Can do.
When the case cover (30) is fixed to the case body (20), the control base housed inside the base case (10) cannot be touched from the outside, and of course the ROM must be replaced. I can't do that either.

Furthermore, since the set screw (60) can be easily rotated in the screwing direction using a screwdriver, it is not possible to rotate the screw in the opening direction opposite to the screwing direction using the screwdriver. More difficult than rotation in the screwing direction.
The fixing part (70) has a fixing hole (73) for inserting the set screw (60) and a head cover (72), and the head (61) is surrounded by the head around the set screw (60). Since it is covered with the cover (72), the set screw (60) cannot be forcibly rotated and loosened by, for example, pinching the head (61) with another tool.

  In this way, turn the set screw (60) in the loosening direction to remove the set screw (60), release the fixed part (70), the mounting part (50) and the gaming machine, and the base case (10) The base case (10) can be fixed from the gaming machine without breaking the breaking portion (71) on the fixing portion (70) side and the breaking portion (52) on the mounting portion (50) side. Therefore, if the base case (10) is removed, the trace will always remain as a rupture of both rupture portions (52, 71).

In the case of inspection, in order to release the case cover (30) and the case main body (20) from being fixed to the gaming machine, both fractured portions provided on the fixing portion (70) and the attachment portion (50) ( 52, 71) is broken by a predetermined means.
Then, if both fractured parts (52, 71) are broken while the fixed part (70) is fixed to the mounting part (50), the fixed relationship between the base case (10) and the gaming machine is broken, and the base case The whole of (10) can also be detached from the gaming machine.

Further, after the inspection, the case cover (30) is closed, and at least one fixing portion (70) other than the broken fixing portions (52, 70) and the corresponding mounting portion (50) are played by the set screw (60). By fixing to the machine, the case cover (30) is again fixed to the case body (20), and the entire base case (10) is fixed to the gaming machine.
As described above, in order to fix the case cover (30) to the case body (20) and to release the game board and the case cover (30), the breaking portion (71) and the mounting portion (50) side of the fixing portion (70) The fractured part (52) of this must be broken, and there is always a trace left unreleased after being fixed.

In addition, since a plurality of fixing portions (70) and mounting portions (50) are provided, the fixing portions (70) and the mounting portions (50) that are not broken even if both fractured portions (52, 71) are broken. As long as is left, the base case (10) can be fixed again to the gaming machine easily and at low cost, and there is no need to replace the base case (10).
(Claim 2)
The base case for a gaming machine according to claim 2 has an inclined surface (64) in one rotational direction of the insertion groove (62) to which the driver is applied, in addition to the feature point of claim 1 described above, and The lower surface of the head (61) has a stepped part (67) and an inclined part (68).

Therefore, according to the base case for a gaming machine according to claim 2, when rotating while inserting a screwdriver into the insertion groove (62), the insertion groove (62) The driver's rotational force can be transmitted to the set screw (60) by the driver coming into contact with the side surface of the screw.
On the other hand, the set screw can be rotated by the rotation of the driver, but when the driver is rotated in the opposite direction, the tip of the driver moves along the inclined surface (64) and the insertion groove (62 ) And it becomes difficult to rotate the set screw (60).

Further, since a step portion and an inclined portion are formed on the lower surface of the head of the set screw (60), when the set screw is screwed into the fixing hole and fixed, the step portion (67) When the set screw bites into the surrounding upper surface and rotates the set screw in the opening direction to loosen it, a large torque is required for the initial rotation of the set screw.
Therefore, it is extremely difficult to loosen the set screw (60) by rotating it in the opening direction using a tool such as a screwdriver.

Since this invention is comprised as mentioned above, there exists an effect as described below.
According to the gaming machine according to claim 1 or 2, in a simple structure, the base case cannot be detached from the gaming machine other than by breaking the fracture portion of the fixed portion, By making it always remain, it is possible to prevent unauthorized modification of the control board, and it is possible to easily remove the board case for inspection, etc., so that unauthorized modification of the board is impossible again. It is possible to provide a board case for a gaming machine that can fix the base case to the gaming machine.

FIG. 6 is a perspective view of the main part of the case cover and the case main body in a state in which all of the rupture portions are broken, FIG. 7 is a perspective view of a set screw, and FIG. The perspective view of a screw is shown, respectively.
(Base case)
In FIG. 1, reference numeral 10 denotes a base case. The base case 10 uses a transparent or translucent resin plate, and a resin plate provided with a large number of small holes in a translucent or opaque resin plate. As a whole, the one housed in the inside is formed of a resin plate that can be distinguished from the outside, and is fixed to a base 11 that is mounted in advance in a slot machine (not shown) as a gaming machine M, for example. .

The base case 10 includes a case main body 20 that houses a control base (not shown), and a case cover 30 that is fixed to the case main body 20 and covers the case main body 20.
In the example of the present embodiment, the slot machine is described as an example of the gaming machine M. However, the gaming machine M to which the control base is attached using the base case 10 is not limited to the slot machine, and the control base is used. It may be a required gaming machine, such as a pachinko machine or an arrangement ball machine.
(base)
The base 11 has a shape that is slightly larger than the outer periphery of the base case 10 and is formed so that the bottom surface of the base case 10 can be stored.

The base 11 is fixed to the gaming machine M via a fixing screw 12 for fixing to the gaming machine M side on the bottom surface facing the bottom surface of the base case 10. Thus, the base 11 cannot be removed from the gaming machine M when the base case 10 is housed in the base 11 on the bottom surface facing the bottom surface of the base case 10.
Further, the base 11 is formed with a pair of left and right four at the left and right corners in a state in which the connecting portions 13 for connecting the case body 20 and the case cover 30 protrude. Each connecting portion 13 is formed so as to protrude toward the case body 20, and a screw through hole 14 is formed at the tip thereof.
(Case body)
Although the case body 20 is not described in detail in the figure, the case main body 20 is formed in a box shape having an opening on the opposite side to the position in contact with the gaming machine M as a whole, and a base storage portion 21 formed in the center thereof, and the base storage portion Five pairs of left and right mounting portions 50 for projecting on the left and right diagonal sides of 21 and mounting the case cover 30 are arranged side by side with the L-shaped short side protruding downwards formed at the lower end thereof Three hinge portions 22 are provided.

  The base storage portion 21 is formed so that a control base can be stored. Although this control base is not shown in the figure, it is a base for performing control related to the game such as winning determination and the number of paid-out medals, and a ROM or RAM that stores a game related program in advance, and a CPU that performs control related to the game Are connected to a switch (not shown), a lamp (not shown), a rotating reel (not shown), and the like arranged on the front side of the gaming machine.

  In addition, the mounting portion 50 is arranged side by side along a side of the base storage portion 21 with a predetermined interval. From the upper right to the lower left, the first, second, third, fourth, and fifth are left and right. 5 each. When the case cover 30 is fixed or when the case cover 30 is fixed to the gaming machine M together with the case cover 30, the pair of left and right mounting portions 50 are used as a set. Since the pair of left and right mounting portions 50 are arranged symmetrically, the left mounting portion 50 will be described below for convenience unless otherwise specified.

  Further, among the five mounting portions 50 arranged so as to project obliquely above the base storage portion 21, all of them have the same configuration except for the third mounting portion 50 at the center thereof, so there is no particular notice. As long as only the first mounting portion 50 and the third mounting portion 50 are described, the remaining second, fourth and fifth mounting portions are arranged corresponding to the four mounting portions 50 of the base 11, respectively. However, since it is the same structure as the 1st attachment part 50, the description is abbreviate | omitted.

The first mounting portion 50 has a single fracture portion 52 that protrudes obliquely to the left from the base storage portion 21 at a position corresponding to the connecting portion 13 of the base 11.
The breaking portion 52 is formed to have a width that can be cut using a simple tool such as a nipper. The tip of the fractured portion 52 is formed in a cylindrical shape, and a passage hole 51 having a diameter through which the set screw 60 can advance and retreat through the lower end is continuous with the screw through hole 14 of the base 11 at the upper end. It is formed as follows.

The third mounting portion 50 has a single fracture portion 52 that protrudes obliquely to the left from the base storage portion 21 at a position where the connecting portion 13 of the base 11 is not formed, like the first mounting portion 50. have. The tip of the fractured portion 52 is formed in a cylindrical shape, and an attachment hole 53 into which a set screw 60 can be screwed is formed at its upper end without penetrating to the base 11 unlike the passage hole 51. .
(Set screw)
The set screw 60 that is screwed into the mounting hole 53 is formed with an insertion groove 62 that can be screwed into the head 61 by a screwdriver. The insertion groove 62 is formed with an inclined surface 64 on the side surface in the counterclockwise direction around the center axis of the set screw 60 so as to rise gently upward from the bottom surface of the insertion groove 62. In the clockwise direction, a vertical portion 63 having a substantially vertical vertical surface is formed.

  Therefore, in the clockwise direction in which the set screw 60 is screwed, the set screw 60 can be rotated by the driver by transmitting the driver's rotation to the set screw 60 by placing the side surface of the tip of the driver against the vertical portion 63. However, when turning the screwdriver counterclockwise to loosen the set screw 60, the tip of the driver rises according to the inclined surface 64, making it difficult to loosen the set screw 60.

Further, the set screw 60 forms a flange portion 65 to enlarge the lower end surface of the head 61, and a stepped portion 67 is formed on the lower end surface. The stepped portion 67 has a counterclockwise direction which is the rotational direction in which the set screw 60 is loosened as a vertical surface, and the thickness of the flange portion 65 is sequentially increased in the counterclockwise direction to form an inclined portion 68. It is thinned so that the thickness of the buttock 65 is restored.
Therefore, if the screw portion 69 of the set screw 60 is screwed into the mounting hole 53 and the lower end surface of the head 61 is pressed against the upper end surface of the peripheral edge of the fixing hole 73, the set screw 60 is rotated counterclockwise. When it is attempted to loosen, the initial rotation resistance is increased by the stepped portion 67, and the inclined surface 64 is formed in the counterclockwise rotation direction of the insertion groove 62 as described above, so that it is stopped by a screwdriver. The screw 60 cannot be loosened and removed.
(Case cover)
The case cover 30 has a substantially rectangular shape similar to the case main body 20, and is formed in a size that covers the entire opening of the case main body 20.

The case cover 30 has a pair of left and right fixing portions 70 for fixing the case cover 30 to the case body 20 at diagonally upper portions on the left and right sides of the case cover 30 along a corner portion of the case cover 30 at a predetermined interval. 5 are provided through the.
The case cover 30 is pivotally supported at one end opposite to the mounting portion 50 so as to be openable and closable with the case cover 30 via the hinge portion 22. Although not shown in detail in the drawing, the hinge portion 22 is temporarily fixed by inserting the L-shaped protruding portion on the case cover 30 side into the hole on the case body 20 side, and the mounting portion 50 and the fixing portion 70 In a state in which the case cover 30 is not fixed, the case cover 30 can be opened to the case main body 20 via the hinge portion 22, and in a state in which the mounting portion 50 and the fixing portion 70 are fixed, the case main body 20 side The projecting portion inserted into the hole is structured so as not to come off.

The pair of left and right five fixing portions 70 are respectively arranged corresponding to the respective mounting portions 50 of the case body 20, and are provided so as to protrude from the side surface of the case cover 30 in the left-right direction, from the upper right to the lower left, The first, second, third, fourth, and fifth fixing portions 70 are configured.
Since both have the same configuration, and the left and right set of fixing portions 70 are also formed symmetrically, unless otherwise specified, the set of fixing portions 70 is provided on the left side. Only the left fixing part 70 corresponding to the part 50 will be described.

The left fixed portion 70 includes two break portions 71 projecting outward from the side surface of the case cover 30 with a predetermined facing interval, and a cylindrical head cover 72 provided at the tip of the break portion 71. It has.
The two broken portions 71 are formed to have a width that can be cut using a simple tool such as a nipper. Moreover, it arrange | positions through the predetermined facing space | interval so that the front-end | tip of cutting tools, such as a nipper, may be easy to insert. The method of breaking may be any method, but for easy cutting, preferably a method of inserting the tip of the cutting tool into the opposing interval formed between the two breaking portions 71 Is good. In addition, if the break portion 71 is formed so as to be cut, it is damaged by receiving external pressure other than for cutting. Therefore, the break portion 71 can be cut easily and is easily broken except by using a tool. In such a configuration, the head cover 72 is supported by the two broken portions 71.

A fixing hole 73 into which a set screw 60 can be screwed is formed at the bottom of the head cover 72 so as to correspond to the passage hole 51 of the mounting portion 50.
Further, the first, second, fourth and fifth fixing portions 70 are screwed with set screws 60 from the fixing holes 73, passed through the passage holes 51 of the mounting portion 50, and connected to the connecting portion 13 of the base 11. The base case 10 can be fixed to the base 11 by being screwed into the screw through holes 14 and tightened, whereby the case cover 30 can also be fixed to the case main body 20.

  The base case 10 can be fixed to the base 11 by fixing the first fixing portions 70 arranged on the left side to the corresponding first mounting portions 50, but further fixing is ensured. Therefore, the first fixing portion 70 is screwed to the first mounting portion 50 on the left side, and the set screw 60 is screwed from the fixing hole 73 of the right fixing portion 70 that is positioned symmetrically. The base case 10 may be fixed to the base 11 by passing through the hole 51 and screwing into the screw through hole 14 of the connecting portion 13 of the base 11 and tightening.

  The head cover 72 has an inner diameter slightly larger than the outer diameter of the head 61 of the set screw 60 so that the set screw 60 can be screwed. The difference between the inner diameter of the head cover 72 and the inner diameter of the head cover 72 is formed so as to have only such a difference that a tool such as pliers is not inserted. Therefore, if the set screw 60 is screwed all the way in, the head 61 and the flange 65 of the set screw 60 are sandwiched with a tool such as pliers, and the set screw 60 is forcibly rotated in the anti-screwing direction (counterclockwise). The set screw 60 cannot be loosened.

Therefore, the set screw 60 once screwed into the fixing hole 73 of the first fixing portion 70, passing through the passage hole 51, and tightened to the screw through hole 14 cannot be loosened. Thus, the case body 20 can be fixed together to the gaming machine M via the case cover 30 by using the first mounting portion 50 and the corresponding first fixing portion 70.
Further, with respect to the third fixing portion 70, the set screw 60 is screwed from the fixing hole 73 and tightened to the mounting hole 53 of the mounting portion 50, so that the third fixing portion 70 is similarly positioned. The third mounting portion 50 can be fixed.

Since the mounting hole 53 of the third mounting portion 50 is formed without penetrating the case cover 30, the case cover 30 can be fixed to the case body 20.
In this way, the case cover 30 can be fixed only to the case body 20 by using the third mounting portion 50 and the third fixing portion 70. Before fixing the gaming machine M to the gaming machine M, It can be stored inside the case 10 and taken out without any trace of opening.

Further, since the set screw 60 screwed into the mounting hole 53 of the third mounting portion 50 cannot be loosened, the case cover 30 cannot be removed from the case body 20.
In order to remove the case cover 30 from the case body 20 regardless of which mounting part 50 and fixing part 70 are used, it is necessary to break the two breaking parts 71 of the fixing part 70.
In particular, the case body 20 and the case using any one of the first, second, fourth, and fifth mounting portions 50 and the corresponding first, second, fourth, and fifth fixing portions 70. When the cover 30 is fixed to the gaming machine M, the base case 10 cannot be detached from the gaming machine M without being separated into the case main body 20 and the case cover 30.

  When the base part 10 is fixed to the gaming machine M using the first fixing part 70 and the first attachment part 50, when both the breaking parts 52 and 71 are broken, the broken fixing part 70 is attached. It is fixed to the part 50 by screwing and is fixed to the base 11, but the fixing part 70 is continuous with the case cover 30 only by the broken part 71, and the mounting part 50 is also connected to the case body 20. Since only the fracture portion 52 is continuous, the fracture portion of both fracture portions 52 and 71 allows the fixing portion 70 to be detached from the case cover 30 and the attachment portion 50 to be detached from the case body 20. In this state, the base case 10 Is pulled away from the base 11, the mounting part 50 and the fixing part 70 screwed to the mounting part 50 are separated from the case main body 20 and the case cover 30 due to the breakage of both broken parts 52 and 71. Then, the base case 10 can be removed from the base 11 while remaining on the base 11.

In order to fix the case cover 30 to the case body 20 again after removing the base case 10 from the base 11, the other pair of left and right mounting portions 50, both broken portions 52 and 71 are not yet broken. A fixing unit 70 may be used.
Further, the depth of the head cover 72 of the fixing portion 70 is such that the head 61 of the set screw 60 protrudes from the upper end of the head cover 72 even when the set screw 60 is screwed only into the fixing hole 73 and temporarily fixed. The head cover 72 has a depth that does not allow the height of the set screw 60 to be substantially equal to the length of the set screw 60.

  Therefore, even when the case cover 30 is not fixed to the case body 20 and the set screw 60 is screwed into the fixing hole 73 and temporarily fixed, the set screw 60 does not hit another object. For example, the set screw 60 can be temporarily fixed during transportation. In addition, when fixed using a pair of left and right mounting portions 50 and fixing portions 70, each of the other pair of left and right mounting portions 50 and fixing portions 70 that are not used is also fixed. By screwing the set screw 60 only into the hole 73, the set screw 60 can be temporarily fixed.

For this reason, when fixing the base case 10 to the base 11, the set screw 60 prepared separately is not lost or removed from another package, so that it is possible to work quickly and carry it. Sometimes no separate packaging is required.
In addition, the case cover 30 can be fixed only to the case main body 20 by using the set screw 60 between the third mounting portion 50 and the third fixing portion 70. In order to remove, the fixing part 70 is continuous with the case cover 30 only by the break part 71, so that the case cover 30 can be removed from the case body 20 by breaking the break part 71 and pulling the case cover 30. Yes, leaving a trace of opening.

Next, a procedure for fixing the case cover 30 to the case main body 20 fixed to the back side of the gaming machine M and containing the control base using the base case 10 having the above-described configuration, the case cover 30 is attached to the case main body 20 A procedure for removing the case cover 30 from the fixed state and a procedure for fixing the case cover 30 to the case body 20 again will be described.
First, the base 11 is fixed in advance to the gaming machine using the fixing screw 12.

Then, the case body 20 containing the control board is fixed to the back side of the gaming machine M, and the case cover 30 is attached to the case body 20.
To attach the case cover 30 to the case main body 20, the case main body 20 and the case cover 30 are separated from each other, the hinge portion 22 is engaged, and the case cover 30 is rotated around the hinge portion 22. Thus, the mounting portion 50 and the fixing portion 70 are aligned.

Next, in the state where the case cover 30 is temporarily fixed to the case body 20, the first, second, fourth, or fifth fixing portion 70 is temporarily set out of the set screws 60 temporarily fixed to the fixing portions 70. Any one of the set screws 60 is screwed into the corresponding first, second, fourth, or fifth mounting portion 50.
For example, the set screw 60 temporarily fixed in the fixing hole 73 of the first fixing portion 70 is further screwed with a screwdriver, the set screw 60 is passed through the passage hole 51 of the first mounting portion 50, and further the set screw When the screw 60 is screwed into the screw through hole 14 of the base 11 and screwed into the screw through hole 14, the case body 20 and the case cover 30 are fixed to the base 11 in the screwed state. Since the base 11 is fixed in advance to the gaming machine M with the fixing screw 12, the base case 10 is fixed to the gaming machine M.

  Note that the set screw 60 that passes through the passage hole 51 of the mounting portion 50 and is screwed to the screw through hole 14 is formed so that it can be screwed only in the screwing direction as described above. Although the set screw 60 can be tightened by using the above tool, the set screw 60 cannot be loosened. Also, the set screw 60 that has passed through the through hole 51 and screwed into the screw through hole 14 is covered with the head cover 72 up to the upper end of the head 61 of the set screw 60. The head 61 of the set screw 60 is not pinched by the tool that holds the screw, and as a result, the set screw 60 cannot be loosened.

Therefore, the case cover 30 cannot be removed from the case body 20 by loosening the set screw 60, and cannot be removed from the gaming machine M in a state where the case body 20 and the case cover 30 are fixed.
By the way, when the third mounting portion 50 and the third fixing portion 70 are used, only the case cover 30 can be fixed to the case main body 20, and when the case cover 30 is fixed to the case main body 20, The case cover 30 cannot be removed from the case body 20 without the trace of removal. The trace of opening remains in the form of breakage of the break portion 71.

Next, in order to remove the base 11 from the base case 10, the two breaking portions 71 of the fixing portion 70 and the breaking portion 52 of the mounting portion 50 are broken using a cutting tool such as a nipper. Both of the breaking portions 52 and 71 are formed to have a width that can be easily broken by a cutting tool such as a nipper. In particular, the two breaking portions 71 are arranged at a predetermined distance from each other. The tip is easy to insert.
Further, since the fixing portion 70 is continuous only with the case cover 30 and the two broken portions 71, the fixing portion 70 and the case cover 30 can be detached when the two broken portions 71 are cut.

Furthermore, since the attachment portion 50 is continuous only with the case main body 20 and the fracture portion 52, when the fracture portion 52 is cut, the attachment portion 50 and the case main body 20 can be detached.
Therefore, when the base case 10 is pulled away from the base 11, the base case 10 can be detached from the base 11 while the fixing portion 70 and the attachment portion 50 are screwed to the base 11.

  In this way, in order to remove the base case 10 from the base 11 and the case cover 30 from the case body 20, the two broken portions 71 and the attachment of the fixing portion 70 screwed to the attachment portion 50 by the set screw 60 are attached. Since the broken part 52 of the part 50 must be broken, the case cover 30 cannot be easily opened, the case cover 30 is opened openly, the control base is remodeled, the ROM storing the program, etc. It cannot be exchanged or removed from the base 11 together with the base case 10 for replacement.

In addition, when the case cover 30 is opened for reasons other than normal inspection or the like, it is immediately revealed that the case cover 30 has been opened improperly because it becomes a trace of opening when both the broken portions 52 and 71 are broken.
Next, after removing the case cover 30 from the case body 20 and inspecting the control base, in order to fix the case cover 30 to the base 11 in a state where the case cover 30 is fixed to the case body 20 again, Since the pair of right and left paired fixing portions 70 and the mounting portion 50, which breaks 52 and 71, cannot be used, the first pair of fixing portions 70 and the mounting portion 50 will be used to explain first. In this manner, the case cover 30 may be fixed to the base 11 via the case body 20 by inserting a screw from the fixing portion 70, passing through the passage hole 51, and screwing into the screw through hole 14 of the base 11.

  If the case main body 20 and the case cover 30 are fixed using the third mounting portion 50 and the third fixing portion 70, the trace is simply removed when the case cover 30 is opened from the case main body 20. Can leave. For this reason, if the case cover 30 is fixed to the case body 20 using the third mounting portion 50 and the third mounting portion 70 before the base case 10 is fixed to the base 11, It is possible to leave an open trace before installation.

In the example of the present embodiment, each pair of mounting portion 50 and fixing portion 70 is provided with four sets in total for fixing the base case 10 and the base 11, so that the first fixing is performed. The case cover 30 can be re-fixed to the case body 20 three times.
In addition, if the fact that the case cover 30 was opened for inspection was recorded, and if the fact that the broken parts 52 and 71 were not found in the record was found, it was immediately found that the case cover 30 was illegally opened. And convenient.

And since it includes a pair of left and right mounting portions 50 and a fixing portion 70, by breaking the break portions 52, 71, even if the case cover 30 is removed from the case body 20, a set of unbroken pieces The case cover 30 can be fixed to the case body 20 again by using the pair of left and right mounting portions 50 and the fixing portion 70, which is extremely economical.
Further, the base cover 10 is fixed to the base body 11 without fixing the base cover 10 with the set screw 60 using the third fixing portion 50 and the third mounting portion 70 that can fix the case cover 30 to the case body 20. For example, the opening before fixing the base case 10 to the gaming machine M can be effectively prevented.
