Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine, and more specifically, a board storage attached to a back surface of a gaming board of a gaming machine such as a pachinko gaming machine or a throttle machine in which a control board for controlling a game is housed. The present invention relates to a fraud prevention mechanism provided with a box, in which fraud prevention measures are taken to prevent fraudulent opening of the substrate storage box.

[0002]

2. Description of the Related Art In recent years, gaming machines such as pachinko gaming machines and throttle machines are mainly used to control the various prize-winning devices and pattern variation display devices provided on the gaming board so as to excite the interest of the game. The control of these winning devices, symbol changing devices, etc. is performed by a logic-controlled circuit board having a large number of electronic components such as ICs and LSIs, or a control board having a microcomputer. A control board for controlling the game contents of such a game machine is generally stored in a board storage box attached to the back side of the game board.

The substrate storage box is made of resin or metal,
A control board or the like on which a large number of various electronic parts such as ICs and resistors are mounted is housed in a box, and in order to prevent a short circuit of a printed circuit on the board, dust and other dust are protected from entering. It is attached to the mechanical plate on the back of the game machine.
For example, in the accessory control device, the CP is included in the control circuit.
U, ROM, RAM, etc. are provided, the game machine is controlled according to the control program stored in the ROM,
Jackpots are also controlled here.

A board housing box for housing such a control board generally has a box structure in which a cover body and a case body are superposed on each other. Of the control board housed inside, the connector portion for electrically connecting to other various electric devices is exposed from the inside of the box, and by inserting various wiring into the connector portion,
It is possible to control the connected electric devices.

[0006] In the act of fraudulently operating the board storage box having such a structure, the cover body serving as the upper lid is removed from the case body, and the electronic parts such as the ROM provided on the opened control board are replaced or the data contents are rewritten. By carrying out, compared to the normal game control, for example, an illegal game control such as frequently generating a big hit is performed.

The structure for sealing the control board in the board storage box which has been used conventionally is such that after the cover body and the case body are assembled with screws, a seal sticker is attached to the joint between them, The storage box was made of a transparent synthetic resin material such as acrylic so that the state of the control board housed inside could be seen from the outside so that fraudulent activity could be confirmed. It was not effective against fraudsters who used stickers or special peeling agents.

In order to prevent such an action, it is conceivable that the substrate storage box has a structure in which it cannot be opened or is extremely difficult to open, and it is sealed only by breaking the box itself. However, considering the maintainability such as ROM inspection and repair by a public organization, it is not realistic.

Therefore, in recent years, the sealing portions provided integrally with the cover body and the case body are separately provided so that the opened traces remain once the sealing is opened. A structure in which a certain sealing member (such as a pin or a screw having a special shape) is used for fastening is adopted. Generally, at least one of the connecting portions between the cover body and the case body and the respective sealing portions is formed so as to be easily cut by a tool such as a nipper, and the connecting portions are cut and sealed. By separating the part where the parts are fastened from each other and the case body or the cover body, it is possible to open the structure. As described above, since it is easy to open and a mark due to the cutting is surely left if it is opened, it is widely adopted because it can prevent fraud and can be handled easily.

Further, a plurality of such sealing portions are provided so that the sealing and unsealing can be performed a plurality of times in consideration of maintainability such as ROM inspection and repair by the public organization. . In other words, since the sealing member used to fasten the sealing parts cannot be used again for sealing,
This is achieved by providing a plurality of sealing locations that form a set of the cover body sealing portion, the case body sealing portion, and the sealing member. For example, if there are eight sealing points and two of them are used for sealing, a total of four times of sealing / opening can be performed.

In this case, a sealing member other than the sealing member used for sealing, that is, 2 used for sealing in the above example.
Regarding the storage of the remaining 6 sealing members other than the above, for example, the manager of the pachinko hall may store them separately, but considering the complexity of handling and loss, etc. It is preferable to attach it. Therefore, various structures have been proposed for the attached structure.

Regarding the attached structure of the sealing member not used for fastening the sealing parts of the cover body and the case body, that is, a spare sealing member (hereinafter, referred to as an unused sealing member), For example, there is a substrate storage box as shown in FIGS. The sealing member used in this substrate storage box has an attached structure in which a temporary holding accommodation chamber is provided in the cover-side sealing portion, and is inserted into the accommodation chamber in advance and temporarily fixed. .

A more detailed description will be given with reference to the drawings. 17 is an external perspective view of the substrate storage box 200, FIG. 18 is an exploded perspective view thereof, FIG. 19 is a top view, and FIG. 20 is an AA cross section of the sealing portion 201 provided on the side surface of the substrate storage box 200.

And a cover body 202 attached to the case body 201
And the insert pin 211 as a sealing member for sealing the control board 203 inside using these.

The case body 201 is formed of a transparent synthetic resin material such as acrylic into a substantially box shape, and the four corners of the main control board 203 placed on the bottom surface thereof are housed and fixed by screws 204. There is. On both the left and right outer surfaces (only one side is shown in the drawing) of the case body 201 that accommodates the main control board 203, there is provided a case box-shaped fixture accommodating base 212 having an upper surface opened as a case-side sealing portion 205. A pin fixing member 213 is integrally connected to the fixing member 201 and is formed by bending a metal plate as shown in FIGS. 20 and 21 inside the fixing member accommodating base 212 with a tapping screw 207. It is fixed.

The pin fixture 213 has an insert pin 21.
An engaging hole 213a is provided which is engaged with the distal end portion 211a of No. 1 so as not to be removed. The engagement hole 2
At the inner peripheral edge of 13a, the tip portion 211a of the insertion pin 211 is
Engaging piece 2 which engages with a concave engaging groove 211b provided around
13b is formed so as to project slightly obliquely downward.

Both left and right outer surfaces of the cover body 202 attached to the case body 201 (only one side is shown in the drawing).
In addition, a plurality of (four in this example) pin insertion bases 215 are provided as cover side sealing portions 206 and are integrally aligned through a connecting portion 218 that is cuttable, and
Screw concealing pieces 217 and 217 are provided on both sides of the pin insertion table 215 to cover the tapping screw 207, which is fixed by screwing the pin fixing tool 213, from above.

Pin insertion bases 215 and 2 arranged in line
As shown in FIG. 21, insertion pins 211 are preliminarily attached to 15, ... The insertion pin 211 is formed by cutting with a metal rod material such as aluminum or integrally formed with a synthetic resin material, and has a flange-shaped head portion 211e and a cylindrical body portion 211d. Cylindrical body 211
A knurled ring portion 211c having a diameter slightly larger than the outer diameter of the main body portion 211d is formed in the middle of d, and the pin insertion base 21 is inserted with the insertion pin 211 loosely inserted.
5 can be inserted. As a result, for example, the manager of the pachinko hall does not need to store the insertion pin separately, and therefore there is no risk of loss or theft, which is convenient for handling.

Further, these pin insertion stands 215, 215,
.. and the connecting portion 2 that connects the side wall of the cover body 202
, 218, ... Are formed into a shape that can be easily cut by a tool such as a nipper.
By cutting the connecting portion 218 of the sealed portion of 18, ...
It will be away from 02.

The substrate storage box 200 having such a structure
The main control board 203 can be sealed and unsealed therein a plurality of times. As shown in FIG. 17, numbers are displayed diagonally (1 to 4 in this case) on the left and right sides of the upper surface of the cover body 202. For example, when sealing for the first time, the left and right numbers are “1”. The insertion pin 211 at the portion marked with is tapped in and sealed. When inspecting the ROM or the like of the main control board 203, it can be opened by cutting the connecting portion 218 of the part to which the left and right numbers "1" are attached. Then, to re-seal, it can be sealed by tapping the insertion pin 211 in the part numbered "2" on the left and right. Since the main control board 203 housed in this way can be opened and sealed multiple times for legitimate reasons such as ROM inspection and repair.
It also has good maintainability.

[0020]

In the substrate storage box 200 having such a structure that the sealing member is preliminarily attached and attached, the unused insertion pin 211, which is an unused sealing member, is inserted into the pin insertion table 215. In order to be attached to and temporarily fixed to the insertion pin 211, a knurled ring portion 211c having a diameter slightly larger than the outer diameter of the main body portion 211d is formed at an intermediate position of the main body portion 211d. In the pin mount 215, the inner diameter of the pin body insertion hole 215b is set to the body 211d of the insertion pin 211.
Larger than the outer diameter of the knurled ring portion 211c
The ring part 211 to be inserted with a size slightly smaller than the outer diameter of the
The structure is adopted so that c can be passed through with a light pushing force. However, this causes a problem in manufacturing and processing.

Cover body 2 provided with this pin mounting base 215
02 is manufactured by resin molding integrally with the pin mounting base 215 from the viewpoint of cost, but normally,
In such molding, as the number of times of manufacturing increases, the precision of molding is generally deteriorated due to deterioration of a mold for molding. That is, the inner diameter of the pin body insertion hole 215b of the pin mounting base 215 is set to the insertion pin 2 to be inserted.
Since the accuracy of forming the ring portion 211c of No. 15 into a size that allows it to pass through with a light pushing force also decreases, depending on the processing precision of the ring portion 211c, depending on the case, the pin body portion insertion hole 215b may be inserted. I don't feel good. The portion other than the inner diameter of the pin body portion insertion hole 215b is not required to be so precise, but the cover body 20
In order to maintain the accuracy of the inner diameter of the pin body portion insertion hole 215b of No. 2, it is necessary to frequently perform maintenance of the mold, and in the worst case, it is also necessary to remanufacture an expensive mold. It was costly.

As a countermeasure against this, a method of maintaining the accuracy by additionally machining only the inner diameter of the pin body portion insertion hole 215b after molding can be considered, but this also causes a problem because the number of processing steps for manufacturing increases. There is no solution.

Further, with respect to the insertion pin, in addition to the flange portion 211e and the engagement groove 211b necessary for fastening the case body and the cover body, it is necessary to machine a knurled ring portion 211c for temporary attachment. Therefore, cost reduction is difficult.

Since the temporary fixing is used,
It is not possible to prevent the act of misusing (unauthorized resealing) an unused sealing member for sealing.

The problem to be solved by the present invention is to provide a structure in which it is difficult to open the board storage box provided in the gaming machine without leaving a trace to prevent fraudulent acts against the gaming machine. It is an object of the present invention to provide a substrate storage box to which a sealing member prepared so that it can be sealed and opened a plurality of times is attached with a simple structure.

As a result, the spare sealing member can be taken out only by releasing the sealing of the substrate storage box, that is, by opening the sealing box.
Since it cannot be illegally taken out without opening, it is possible to prevent abuse of the sealing member (illegal resealing). Further, since the structure is simple, it is possible to reduce the manufacturing cost.

In this case, as described in claim 2, the accommodating portion is formed with the accommodating hole into which one end side of the sealing member is inserted, and the other end side of the sealing member is restricted from moving in the inserting direction. A fraud prevention structure having the above-mentioned effect with a simple shape and structure can be realized by adopting a configuration in which the head has a head and the lid is provided so as to restrict the movement of the head in the pulling-out direction. Because it is possible, its production is easy and the cost is low.

Furthermore, when the sealing member is integrated and provided in one place as described in claim 3, the number of remaining unused sealing members can be determined only by confirming the integrated position. Can be grasped.

According to a fourth aspect of the present invention, a gaming machine is provided with a board storage box including a case body for housing a control board for controlling a game, and a cover body attached to the case body. In the above, the case body and the cover body are provided with a plurality of sets of sealing portions that are fastened to each other in a sealed state, and are used to fasten the case side sealing portion and the cover side sealing portion. A plurality of sealing members are provided, one of the case body and the cover body is provided with a housing portion for housing the entire sealing member, and the other is provided with the case body and the cover body. When a cover is attached, a lid portion is provided to cover the containing portion of the enclosed sealing member, and in the state where the substrate storage box is sealed, the sealing member is formed by the containing portion and the lid portion. By being housed so that it cannot be taken out That.

According to the substrate storage box having the above structure, the spare sealing member used for fastening the case-side sealing portion and the cover-side sealing portion is provided in at least one of the case body and the cover body. The storage portion provided and the lid portion provided on the other side hold the sheet in a sealed state so that it cannot be taken out. That is, the entire sealing member is accommodated by the accommodating portion, and when the case body and the cover body are adhered, the accommodated portion is covered by the lid portion. I can't even touch it. Since sealing is performed in this state, these spare sealing members cannot be taken out unless the case body and the cover body are detached by releasing the sealing.

As a result, since the spare sealing member can be taken out only by releasing the sealing of the substrate storage box, there is no risk of loss, and since it cannot be taken out without opening the sealing member, Abuse (illegal resealing) can be prevented in advance. Further, since the structure is simple, it is possible to reduce the manufacturing cost. Furthermore, since the entire sealing member is housed,
I can't even touch it.

Since 99 g is provided in a convex shape, it is easy to store the product smoothly.

The substrate storage box 90 having such a structure
The main control board 82 can be sealed and unsealed therein a plurality of times (four times in this embodiment). Numbers (1 to 4 in this case) are diagonally displayed on the left and right side surfaces of the cover body 92 (only one side is shown). After the cover body 92 is attached to the case body 91, the cover body 92 is first sealed. When inserting, the pin insertion table 9 with the number "1" on the left and right
Two insertion pins 95 are struck in 6 and sealed.

When opening the main control board 82 to inspect the ROM or the like, the connecting portions 96a at the left and right numbers "1" are cut and opened. After the inspection of the ROM, sealing can be performed again by tapping two new insertion pins 95 into the pin insertion table 96 to which the right and left numbers "2" are attached. It is said that the main control board 82 thus stored can be opened and sealed a plurality of times (four times in this embodiment) for proper reasons such as ROM inspection and repair, and the workability is also good. It is a thing.

Next, with respect to the structure in which the unused insertion pins 95 used for sealing the case body 91 and the cover body 92 having such a structure are provided in the substrate storage box 90 as an accessory, FIGS. This will be described with reference to FIG. In this embodiment, eight insertion pins 95 are used so that sealing and unsealing can be performed four times in total. The remaining six insertion pins 95 other than the two insertion pins 95 used for the first sealing (that is, 2
The insertion pin 95) used for the subsequent sealing is a plate-shaped lid portion 101 extending outward from one side wall of the cover body 92 and an outer side from the one side wall of the case body 91. It is provided so as not to be taken out by the plate-shaped accommodating portion 102 extending toward the side.

As shown in FIG. 9, the plate-shaped accommodating portion 10
2 is a housing hole 1 having an inner diameter slightly larger than the outer diameter of the main body 95b of the insertion pin 95 and smaller than the outer diameter of the head 95a.

Since the head portion 95a is locked at the entrance side of the accommodation hole 102a, the downward movement is restricted.

Although the insertion pin 95 can be easily taken out in a state where the insertion pin 95 is only accommodated in the accommodation hole 102a, when the cover body 92 is attached, the insertion pin 95 can be removed.
And as shown in FIG. 11, the lid portion 101 of the cover body 92 is
Is positioned above the head portion 95a of the insertion pin 95, the movement of the insertion pin 95 in the take-out direction is restricted. That is, when the cover body 92 is attached, it cannot be taken out unless the cover body 92 is attached and detached. If the insertion pin 95 is used for sealing in this state, the case body and the cover body cannot be detached unless the sealing is released.

As a result, the spare insertion pin 95 can be released only by unsealing the substrate storage box, that is, by opening it.
Since it cannot be taken out, there is no risk of loss, and since it cannot be taken out illegally without opening, it is possible to prevent abuse (illegal resealing) of the insertion pin 95 as a sealing member. it can. Further, since the structure is simple, it is possible to reduce the manufacturing cost.

Next, the procedure of assembling the board storage box 90 having such a structure and operating the insertion pin 95 to seal the main control board 82 in the box will be described with reference to FIGS.
This will be described using 6.

First, as shown in FIG. 13A, the pin fixture 98 is accommodated and fixed in the accommodation groove 99a of the fixture accommodating base 99 provided in the case side sealing portion 93 of the case body 91. The main control board 82 is screwed and fixed in the case body 91. Then, as shown in FIG.
The cover body 92 is attached from above.

After the attachment, as shown in FIG. 14A and FIG. 5, the insertion pin 95 is inserted from the side into the pin insertion table 96 of the cover body 92 with the number "1". Then, as shown in FIGS. 14B and 16, the head portion 95a of the inserted insertion pin 95 is pushed from the side by using a tool such as a screwdriver to screw the tip portion 95c. The engaging groove 95d engages with the engaging claw 98b formed on the inner peripheral edge of the engaging hole 98a of the pin fixture 98.

In this way, the pin inserted and fixed by being engaged with the pin insertion base 96 provided on the cover body 92 and the accommodation groove 99a of the fixture accommodation base 99 provided on the case body 91 by the insertion pin 95. When the fixture 98 is connected, the case body 91 and the cover body 92 cannot be separated, and the main control board 82 is sealed in the box.

Further, as shown in the figure, the pin fixing member 98 has the entire front side on which the insertion pin 95 is inserted.
Since the pin fixture 98 is covered with 9b and accommodated in the accommodating groove 99a, the pin fixing tool 98 can be disengaged from the engaging recess 99c or the like, which is an engaged portion in the accommodating groove 99a, by an illegal act. Is the front stand 99b and the housing groove 99 that cover it.
It is necessary to destroy a, that is, the fixture housing 99 itself. If such a destruction can leave the traces with certainty, and it is extremely difficult to restore the traces to erase it, if the control board is unsealed due to fraudulent acts. In addition to being detected early, it is not possible to erase the traces of fraudulent acts, so it is possible to suppress such fraudulent opening actions by fraudulent persons.

The base storage box 9 thus sealed
In order to open 0 from the ROM of the main control board 82 for proper reasons such as inspection and maintenance, it is connected to the cover body 92 of the pin insertion table 96 to which the number “1” on the left and right on which the insertion pin 95 is tapped is attached. By cutting the two connecting portions 96a
The cover body 92 and the pin insertion table 96 into which the insertion pin 95 has been hit are separated. Then, the cover body 92 is removed from the case body 91, and the opened main control board 82 is inspected.

After the inspection and maintenance of the ROM are finished, in order to reseal, two out of the six unused insertion pins 95 accommodated in the accommodating portion 102 are taken out. The new insert pin 95 taken out is inserted into the left and right pin insert bases 96, which are numbered "2" this time, and similarly, a tool such as a screwdriver is tapped in from the left and right sides to perform the main control again. The substrate 82 can be sealed in the substrate storage box 90.

As described above, since the insertion pin 95 can be taken out only by opening the substrate storage box, there is no possibility of losing the unused insertion pin 95. Further, since it has a simple shape and structure, its manufacture is easy and the cost is low. Further, if the unused insertion pins 95 are collectively provided in one place as in the above embodiment, the number of remaining unused sealing members can be grasped only by confirming the aggregated place. And convenient.

As another embodiment, as shown in FIG. 12, partition walls 104a, 104 are provided on the left and right sides of the case body 91 on one side.
Housing portions 104, 104 are provided which are separated from the portion for housing the control board by a, and three insertion pins 95 are housed in each of the housing portions 104, 104. In this case, the upper and left upper wall portions of one side of the cover body 92 have just the functions as the lid portions 103 and 103 without separately providing the cover body 92 with a portion functioning as a lid portion (only one side is shown). Even in the structure having the insertion pin 95 as described above, the insertion pin 95 cannot be taken out when the cover body 92 is attached. Moreover,
Since the entire insertion pin 95 is housed, it cannot even be touched.

Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the spirit of the present invention. For example, although the configuration in which the unused insertion pins 95 are integrated in one place is shown in the embodiment, it is of course possible to divide into a plurality of parts and dispose them in the vicinity of the sealing portion used for sealing. Further, in the embodiment, the insertion pin 95 used first is not housed,
Although the configuration is shown in which only the insertion pin 95 used after the second time is accommodated, it goes without saying that the first insertion pin 95 may also be accommodated.

Further, in the embodiment, the structure having the insert pin 95 as the sealing member, the case side sealing portion 93 as the sealing portion, and the cover side sealing portion 94 is shown. It is needless to say that the present invention is not limited to the above, and can be applied to, for example, the substrate storage box 200 of FIGS. In short, it goes without saying that the structure of the present invention can be adopted as long as it is a sealing member separately provided for permanently sealing the cover of the substrate storage box and the case.
