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 regular ROM storing a program for controlling a game attached to a control base housed in the base case has been changed, and a program relating to a play rate is changed. There was a need to effectively prevent fraudulent acts of changing to a modified ROM that was illegally modified but could not be identified in appearance.
In addition, it is necessary to form the case cover so that it can be opened for inspection or the like.
In order to satisfy these two needs at the same time, a control board having a ROM or the like that stores a program for controlling a game, a board comprising a case body fixed to the gaming machine and a case cover covering the case body The case cover is housed inside the case, and the case cover and the case body are attached to the gaming machine via a screw that is difficult to rotate in the opening direction, and the mounting part cannot be opened to the gaming machine side. It is known that, by fixing, the base case cannot be detached from the gaming machine other than by breaking the break part provided in the mounting part, so that the trace of the base case is always left. It has been.

Japanese Patent Laid-Open No. 11-60836

  However, in the above-mentioned conventional base case for gaming machines, in order to open the case cover, the broken part must be broken each time, and the case cover is opened again for convenience of inspection or the like. If the work of fixing to each other is repeated, all the rupture portions of the attachment portion formed in advance may be broken, and all the attachment portions may be used up. In this case, it is sufficient to use a new base case for the mounting part on the base case side, but on the gaming machine side, the broken mounting part remains fixed and cannot be used again. There was a point.

  Therefore, the base case for a gaming machine according to claim 1 does not allow the base case to be detached from the gaming machine other than the breakage of the mounting portion, and the trace of the base case is always left. On the other hand, it is intended to provide a base case for a gaming machine that can be used continuously even when the base case is repeatedly opened by making it possible to replace the fixing member anew. is there.

(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)
A base case for a gaming machine according to claim 1 includes a base case (10) for storing a control base for controlling the gaming machine and a base (20) for fixing the base case (10) to the gaming machine. ), And the base case (10) includes a case body (30) and a case cover (30) fixed to the case body (30) so as to cover the case body (30). 40), and the case cover (40) and the case main body (30) are sealed so as not to be open unless the trace of the opening is apparently apparent due to the breakage of the second fracture portion (111). The case cover (40) is provided on the case cover (40), and the case cover (40) is attached to the base (20) via the first fractured portion (101) whose appearance of opening is apparently clear. The mounting portion (100) is attached to the base (20) via a fixing member (50), and the fixing member (50) is attached to the base (20). The case cover (40) is formed to be detachable from the base (20) in a state before being attached to the base (20), and the fixing member (50) includes the attachment portion (100). The first breaking portion (101) is formed so that the base case (10) can be removed from the fixing member (50) by the breakage. The second fracture portion (111) seals the case cover (40) and the case body (30), and is open even when the case cover (40) is attached to the base (20). Is provided at the position of the case cover (40) so that the trace of the appearance is clear, and before the base case (10) is fixed to the base (20), the second fracture portion (111) is fractured. Thus, the case cover (40) and the case body (30) are formed to be openable.

Therefore, according to the base case for a gaming machine according to claim 1, with the control base housed in the case body (30), the gaming machine is connected to the gaming machine via the fixing portion (70) corresponding to the mounting portion (100). By fixing, the case cover (40) can be fixed to the gaming machine together with the case main body (30).
Since the case body (30) is covered with the case cover (40) and is fixed to the gaming machine, the control base housed inside the base case can be touched from the outside. Of course, ROM cannot be exchanged.

  As described above, since the case cover (40) cannot be released from being fixed from the gaming machine without breaking the fracture portion of the attachment portion (100), the base case (10) is temporarily removed from the base (20). If it is removed, the trace of the opening will always remain as a breakage of the first breakage portion (101) of the attachment portion (100) that is apparent in appearance.

In addition, when inspecting the control base after fixing the base case (10) to the gaming machine, in order to release the case cover (40) and the case body (30) from being fixed to the gaming machine, The first fracture portion (101) provided in 100) is fractured by a predetermined means.
Then, if the first breaking portion (101) is broken while the mounting portion (100) is fixed to the fixing portion (70), the fixing relationship between the case cover (40) and the gaming machine is cut off, Since the case cover (40) covering the case main body (30) can be removed while the part (100) remains in the fixed part (70), the case main body (30) can also be detached from the gaming machine.

  Therefore, in order to release the case cover (40) and the fixing to the gaming machine via the attachment portion (100) and the fixing portion (70), the first breaking portion (101) of the attachment portion (100) is removed. It must rupture, so there is always a trace left unreleased.

Further, if a plurality of mounting portions (100) and fixing portions (70) are provided, even if the breaking portion (101) is broken and the mounting portion (100) and the fixing portion (70) cannot be reused, The base case (10) can be fixed to the gaming machine again by using the unbroken mounting part (100) and the fixing part (70) corresponding thereto.
Furthermore, by repeating the opening and re-fixing, the mounting part (100) and the fixing part (70) that can be used for re-fixing the base case 10 to the gaming machine are obtained by breaking the first breaking part (101). It will decrease and disappear at the end.

In that case, prepare a new case cover (40) and use the mounting portion (100) of the new case cover (40), while the fixing portion (70) is fixed from the gaming machine to the fixing member (50). Is removed and replaced with a new fixing member (50), and by using the fixing portion (70) of the new fixing member (50), the base case (30) is again replaced without replacing the case body (30). 10) can be fixed to the gaming machine.
Similarly, the case cover (40) and the case body (30) are sealed so as not to be opened unless the trace of the opening is due to the apparently broken second broken portion (111). Therefore, when the case cover (40) is opened from the case body (30), the appearance of the breakage of the second breakage portion (111) becomes apparent in appearance.

Since this invention is comprised as mentioned above, there exists an effect as described below.
According to the base case for a gaming machine according to claim 1, the base case cannot be detached from the gaming machine other than the fractured portion 101 of the mounting portion, and the trace of the base case is always left. On the other hand, by making it possible to newly replace the fixing member, it is possible to provide a base case for a gaming machine that can be used continuously even when the base case is repeatedly opened.

(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 shown in FIG. 1, the inside case is formed of a resin plate that can be distinguished from the outside. For example, a base case 10 that is mounted in advance in a slot machine (not shown) as a gaming machine M is provided. It is fixed via the left and right bases 20 arranged opposite to each other.

The base case 10 includes a case main body 30 that houses a control base (not shown), and a case cover 40 that is fixed to the case main body 30 and covers the case main body 30.
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.
(Left and right base)
Each of the left and right bases 20 has a pair of screw insertion holes 21 formed on the rear surface parallel to the surface of the gaming machine to which the right and left bases 20 are attached. By inserting screws as fixing tools into the screw insertion holes 21 and screwing them through to the gaming machine, It is formed to be fixable to the gaming machine. Each screw insertion hole 21 is covered with the fixed base case 10 in a state where the base case 10 is fixed to the left and right bases 20, and is fixed to the gaming machine at a position where it cannot be touched from the outside. The base case 10 is effectively prevented from being removed together with the left and right bases 20.

  In addition, the right base 20 rises vertically from the right base 20 at a position facing the right side of the case cover 40 and engages with the right side of the case cover 40 to play the case cover 40 A locking projection 22 for pressing against the machine side is formed of an elastically deformable material. Therefore, when the case cover 40 is pressed against the fixed right base 20, the locking protrusion 22 is once opened outward, and after passing over the protruding portion of the case cover 40, it returns to its original position. The case cover 40 is locked to the protruding portion, and the case cover 40 is pressed toward the gaming machine.

The left base 20 is formed with a pair of rectangular engagement holes 23 for engaging with the case body 30 in parallel with the rear surface of the base 20.
On the other hand, the right base 20 has a pair of rising pieces 24 rising in the same direction from the rear surface at a predetermined interval, and is continuous with the rising pieces 24 and is parallel to the rear surface of the right base 20 and is mutually connected. A pair of support portions 26 having an L-shaped cross section formed of a pair of bent pieces 25 bent in opposite directions are formed. A fixing member 50 is formed between the pair of support portions 26 so as to be insertable. The fixing member 50 is formed to have a length that can be inserted between the above-described rising pieces, and to have a thickness that can be inserted into a gap formed between the rear surface of the right base 20 and the bent piece 25. Has been. Therefore, the fixing member 50 is formed so as to be able to be inserted into and removed from the support portion 26 from the left direction substantially parallel to the rear surface of the right base 20.

  The right base 20 is formed with a detachment preventing member 60 for preventing detachment when the fixing member 50 is inserted. The separation preventing member 60 is formed at a position farther in the separation direction of the fixing member 50 than the support portion 26 of the fixing member 50, and a swinging piece 61 that swings with respect to the rear surface of the right base 20 and the swinging member 61. The moving piece 61 is formed at an end on the support portion 26 side, and is formed from an inclined claw 62 that is inclined upward toward the support portion 26. When inserting, when the bottom surface of the fixing member 50 comes into contact with the rear surface of the swing piece 61 and further moves the fixing member 50 in the direction of the support portion 26, it comes into contact with the inclined claw 62. In addition to being formed so as to be able to swing with respect to the rear surface of the base 20, the inclined claw 62 is inclined upward in the direction of the support portion 26, so there is no change in the position of the fixing member 50 relative to the base 20, The swing piece 61 can be pushed down to such an extent that the claw 62 is not inclined, and the fixing member 50 can be inserted into the support portion 26 in this state.

  When the insertion of the fixing member 50 into the support portion 26 is completed, there is no longer any pushing down of the swing piece 61, so the swing piece 61 returns to the original position where the inclined claw 62 is inclined upward again. When the inclined claw 62 returns to the original position, the fixing member 50 is prevented from being detached from the support portion 26 on the vertical surface of the inclined claw 62 on the support portion 26 side. In order to remove the fixing member 50 from the support portion 26, the swinging piece 61 is pushed down with a finger or the like so that the inclined surface of the inclined claw 62 is substantially the same as the upper surface of the base 20. That's fine.

The fixing member 50 is formed with four fixing portions 70 for fixing the case cover 40.
Since all of the four fixing portions 70 have the same shape, description of the other fixing portions 70 having the same shape will be omitted by describing one shape.
The fixed portion 70 is formed with a cylindrical member 71 protruding from the rear surface of the fixed member 50 in a direction opposite to the gaming machine, and the cylindrical member 71 is opened from the axis to the gaming machine direction. A screw fixing hole 72 is formed.
(Case body)
Although not described in detail in the figure, the case main body 30 has a box shape having an opening on the side opposite to the position in contact with the gaming machine M as a whole.

The case body 30 has a base storage portion for storing the control base formed in the center thereof, and above the base storage portion, a left and right for engaging with the case cover 40 so as to be openable and closable. A hinge portion 80 on the side of the pair of case main bodies 30 is provided.
Although not shown in the figure, the control board is a board for performing game-related control such as winning determination and the number of medals to be paid out. In addition to a CPU that performs the operation, it is 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 case body 30 is formed with a total of four connected portions 90 for fixing to the case cover 40, two on each side.
Since each connected portion 90 is formed in the same shape, the description of one connected portion 90 is omitted, and the description of the other connected portions 90 is omitted.
The connected portion 90 has a connecting portion protruding outward from the case body 30 and a cylindrical portion formed at the tip of the connecting portion. A connected hole 91 for screwing a screw is formed at the tip of the cylindrical portion.

Further, when the case body 30 is fixed to the gaming machine, the case body 30 is formed so as to be fitted inward with respect to the case cover 40 covering from above and cannot be detached in the gaming machine direction or the anti-gaming machine direction. Has been. Therefore, when removing the case body 30 from the gaming machine, it is necessary to remove the case cover 40 from the gaming machine in advance.
(Case cover)
The case cover 40 has a substantially rectangular shape similar to the case main body 30, and is sized to cover the entire opening of the case main body 30. In a state where the case cover 40 is disposed so as to close the case main body 30, the case cover 40 is formed so as to be non-slidable in the horizontal direction with respect to the case main body 30, facing the case main body 30, and separating away from the case main body 30. It is formed to be movable only. Therefore, as will be described later, when the case cover 40 is fixed to the gaming machine with the case cover 40 covering the case main body 30, the case main body 30 is indirectly fixed to the gaming machine accordingly. .

  The case cover 40 is pivotally supported by the case cover 40 via a hinge portion 80 so as to be openable and closable. Although not shown in detail in the drawing, the hinge portion 80 is temporarily fixed by inserting the L-shaped protruding portion on the case cover 40 side into the hole on the case body 30 side, The case cover 40 can be opened with respect to the case body 30, and when the case body 30 and the case cover 40 are fixed, the protruding portion inserted into the hole on the case body 30 side cannot be removed. It has become.

In addition, the case cover 40 has a pair of engaging protrusions 41 that protrude into the left side at positions corresponding to the pair of engaging holes 23 formed in the left base 20. Is formed. The case cover 40 can be easily fixed to the left base 20 by inserting the one engaging protrusion 41 from the right side.
Further, on the right side of the case cover 40, four mounting portions 100 for fixing the case cover 40 to the left and right bases 20 are provided so as to protrude from the case cover 40 at a predetermined interval. ing.

Since all of the four attachment portions 100 have the same structure, only one attachment portion 100 will be described, and description of the other attachment portions 100 will be omitted.
The attachment portions 100 are respectively arranged corresponding to the fixing members 50 attached to the base 20, and are provided so as to protrude from the side surface of the case cover 40 to the right side.
The mounting portion 100 includes two first break portions 101 projecting outward from the side surface of the case cover 40 with a predetermined facing interval, and a cylindrical head provided at the tip of the first break portion 101. Part cover 102.

  The two first breaking portions 101 are formed to have a width that can be cut using a simple tool such as a nipper, for example, and at a predetermined facing interval so that the tip of a cutting tool such as a nipper can be easily inserted. Is arranged through. Any method may be used for the breaking. However, in order to cut easily, the tip of the cutting tool is preferably placed at an opposing interval formed between the two first breaking portions 101. The method of inserting is good. In addition, if the first breakable portion 101 is formed so as to be cut, the first breakable portion 101 can be cut and broken using a tool because it is damaged by receiving external pressure other than for cutting. Other than this, the head cover 102 is supported by the two first broken portions 101 so as not to be broken easily.

An attachment hole 103 into which a screw can be screwed corresponding to the fixing hole 72 of the cylindrical member 71 of the fixing portion 70 is formed in the bottom portion of the head cover 102.
Then, by inserting a screw into the mounting hole 103 of any of the mounting parts 100, passing through the mounting hole 103, and screwing into the fixing hole 72 of the corresponding fixing part 70, the case cover 40 is attached to the right base 20 Can be fixed to.

  The head cover 102 has an inner diameter slightly larger than the outer diameter of the head of the screw so that the screw can be screwed in. The outer diameter of the head of the set screw and the inner diameter of the head cover 102 Is formed so as to have only a difference such that a tool such as pliers is not inserted. Therefore, if the screw is screwed in as far as it will go, the screw head or buttock may be pinched with a tool such as pliers and the screw 60 may be forcibly rotated in the anti-screwing direction (counterclockwise) to loosen the screw. I can't.

  Therefore, once the screw is screwed into the mounting hole 103 of the mounting part 100 and tightened to reach the fixing hole 72, the screw cannot be loosened, so the case cover 40 is fixed to the left and right bases 20. The case body 30 is fitted inside the case cover 40 and is formed so as to be opposed to the case cover 40 and movable only in the direction away from the case cover 40. Cannot be detached from the right base 20, and the case main body 30 is also indirectly fixed to the gaming machine while being sandwiched between the gaming machine and the case cover 40 fixed to the gaming machine.

In any case, in order to remove the case cover 40 from the right base 20, it is necessary to break the two first breaking portions 101 of the mounting portion 100, regardless of which mounting portion 100 and fixing portion 70 are used. Therefore, the fact that the case cover 40 is removed from the gaming machine or the case cover 40 is opened is obvious.
In order to fix the case cover 40 to the base 20 after removing the case cover 40 from the left and right bases 20, the first breaking part 101 is not yet broken, and the other mounting parts 100 correspond to this. The fixing part 70 to be used may be used.

Furthermore, when the fixing and detachment of the case cover 40 and the right base 20 are repeated, the attachment portion 100 that does not break the first breakage portion 101 disappears, and the attachment portion 100 is broken due to the breakage of the first breakage portion 101. Only a plurality of fixing portions 70 that are left behind and cannot be used again are left.
In this case, by removing the fixing member 50 from the support portion 26 and inserting a new fixing member 50 into the support portion 26, the fixing portion 70 without the attachment portion 100 can be used. The case cover 40 that has broken all the attachment portions 100 can be fixed to the right base 20 and detached after the fixing by replacing the case cover 40 with a new case cover 40.

Therefore, the left base 20 can be used as it is, the right base 20 can be used as it is, and can be reused by simply replacing the fixing member 50, and a new base 20 can be used. Therefore, the cost can be reduced and the resources can be effectively used.
The case cover 40 is formed with a total of four connecting portions 110 for fixing to the case main body 30, corresponding to the connected portions 90 of the case main body 30, two on the left and right. .

Since each connection part 110 is formed in the same shape, description of the other connection part 110 is abbreviate | omitted by describing one connection part 110. FIG.
The connecting portions 110 are disposed corresponding to the connected portions 90 of the case body 30, and are provided so as to protrude downward from the lower surface of the case cover 40, respectively.
The connection portion 110 includes two second break portions 111 projecting outward from the side surface of the case cover 40 with a predetermined facing interval, and the second break portion 11 1. A head cover 112 having a cylindrical shape provided at the tip is provided, and a connection hole 113 for inserting a screw is formed through the bottom of the head cover 112.

Since the connecting portion 110 has the same structure as the mounting portion 100 described above, the description thereof is omitted.
Further, since the relationship between the connecting portion 110 and the connected portion 90 is the same as the relationship between the mounting portion 100 and the fixing portion 70 described above, the case main body does not leave an open trace. It is difficult to open the case cover 40 with respect to 30.

Next, a method for fixing the base case 10 having the above configuration to the gaming machine will be briefly described.
First, the left and right bases 20 are fixed to the gaming machine such that the facing distance is equal to the width of the base case 10.
In order to fix the left and right bases 20 to the gaming machine, screws are inserted from the screw insertion holes 21 until they are penetrated through the gaming machine.

  Then, the fixing member 50 is inserted into the support portion 26 of the fixed right base 20. When the fixing member 50 is inserted, the fixing member 50 is moved so as to be slid rightward. On the bottom surface of the fixing member 50, the swing piece 61 is pushed down toward the gaming machine, and the inclined claw 62 moves toward the gaming machine. Then slide it further. When the fixing member 50 is slid to some extent, the inclined claw 62 comes off the bottom surface of the fixing member 50 and returns to the original position. The fixing member 50 is fixed in a state where the inclined claw 62 is in contact with the side surface of the fixing member 50.

On the other hand, the case cover 40 connected by the hinge part 80 is closed in a state in which the base is stored in the case main body 30, and the connected part 90 of the case main body 30 is made to correspond to the connecting part 110 of the case cover 40.
The case cover 40 is attached to the case body 30 by causing the connection part 110 and the connected part 90 to correspond to each other, inserting a screw from the connection hole 113 of the connection part 110, and screwing to the connected hole 91 of the connected part 90. Fixed. Usually, the case cover 40 can be fixed to the case body 30 by fixing the right and left pair of connected portions 90 and the connecting portion 110 with screws, and the base case 10 is integrated. In order to open the case cover 40 from this state, the fixing by the two connected portions 90 and the connecting portion 110 can be performed only by the method of breaking the pair of second broken portions 11 1.
For this reason, since the connection part 110 and the to-be-connected part 90 are formed in four mutually, after fixing the to-be-connected part 90 and the connection part 110 once, a pair of 2nd fracture | rupture parts 11 1 are fractured | ruptured. Thus, when the case cover 40 is opened, the case main body 30 and the case cover 40 are fixed again by using the two unused connection portions 110 and the connected portion 90 only once. be able to.
In addition, since the head cover 112 is formed in the connection part 110 as in the case of the attachment part 100, it is difficult to turn the screwed screw in the loosening direction.

With the case body 30 and the case cover 40 fixed and the base case 10 integrated, the base case 10 is fixed between the left and right bases 20 fixed to the gaming machine.
First, the pair of engaging protrusions 41 formed on the case cover 40 are inserted into the pair of engaging holes 23 of the left base 20, respectively. In a state where the pair of engaging protrusions 41 are inserted, the base case 10 is prevented from moving leftward from the left base 20, and is also prevented from moving in the anti-gaming machine direction. .

Next, the right side of the case body 30 is aligned with the base 20 on the right side, and the fixing portion 70 of the base 20 and the mounting portion 100 of the case cover 40 are made to correspond to each other.
Then, the case cover 40 of the base 20 is fixed using any one of the attachment portions 100 and the fixing portions 70 corresponding thereto.
Since the case main body 30 cannot be detached from the case cover 40 in a state of being fitted in the case cover 40, the case main body 30 cannot touch a base housed inside the case main body 30.

  Further, in order to open the case cover 40, the case cover 40 is housed inside the case body 30 unless the first broken portion 101 of the mounting portion 100 used for fixing is broken. Unable to take out the foundation. Therefore, the case cover 40 cannot be opened even if the connection between the case cover 40 and the case main body 30 is canceled by breaking the first broken portion 101 of the connection portion 110.

  Further, even after the case cover 40 is opened at one end, the base case 10 can be fixed again to the gaming machine via the left and right bases 20 using the mounting portion 100 and the fixing portion 70 that are not used for fixing. Furthermore, when all of the mounting part 100 and the fixing part 70 have been used, the fixing part 70 is replaced by replacing only the case cover 40 of the base case 10 with a new one. By exchanging the fixing member 50, the base case 10 can be re-fixed again while the left and right bases 20 are fixed to the gaming machine.
