Description

  The present invention relates to a gaming machine having a control device in which a control board is housed in a board box.

  For game machines such as pachinko machines that play games with winning or non-winning game balls, and slot machines that play games with a combination of multiple numbers and symbols, the base board is covered with a transparent board box. It is equipped with a control device that houses the board. And most of the games are controlled by this control device. Therefore, in recent years, the board box of the control device is disassembled, and the ROM etc. in which the entire control board inside or the game program is recorded are stored. An illegal act of exchanging it with a content that is advantageous to the fraudster has been a problem.

  Therefore, in order to detect such illegal acts, the supervisory authority inspects the ROM, which is an electronic component to be inspected. However, as a further countermeasure against the illegality, the base body and the cover body are sealed in a joined state. In addition, there is a sealing means such as a rivet that requires destruction of a part of the base body or the cover body when releasing the seal (for example, see Patent Document 1).

JP-A-9-225092

  In the conventional board box, when the sealing is illegally released and the cover body is opened, the control board inside is completely exposed. In this state, for example, if the ROM of the control board is replaced with an illegal one and the cover body is closed back, the discovery is not easy. Of course, the seal of the board box will be destroyed when it is released, so the trace remains.For example, prepare multiple sets of the same kind of board box, one destroys the base body and acquires an intact cover body, In one of the above, a camouflage operation may be performed in which the cover body is destroyed to obtain an intact base body, and the obtained intact cover body and the base body are combined and restored.

  The present invention has been made in view of the above, and an object of the present invention is to provide a control device that can effectively prevent an unauthorized work in which an electronic component to be inspected on a control board is replaced with a modified product. It is to provide a gaming machine that is difficult to perform.

In order to achieve the above object, the present invention as described in claim 1,
It has a control device that houses the control board in the board box,
The board box is
The base body located on the front side when the side close to the player in the installed state is `` front '' and the opposite side is `` rear '',
A transparent cover body that covers the rear side of the base body and is formed in a front opening shape by surrounding the periphery of the rear surface member facing the base body with a peripheral frame member;
The base body and the cover body are sealed in a joined state, and the base body or the cover body or a sealing means that requires self-breakage when releasing the seal,
The control board is
A circuit board attached to the inside of the board box;
In a gaming machine having a plurality of electronic components including at least one electronic component to be inspected mounted on the circuit board,
The inspection target electronic component provides a gaming machine attached to the cover body by a fixing means having no removing means.

Further, as described in claim 2,
The control board arranges the electronic component to be inspected in a region of the circuit board on the side facing the portion where the sealing means of the cover body is provided,
The cover body is
The control board is divided into a detachable cover that covers the area where the electronic components to be inspected are provided, and a fixed cover that covers the other area of the control board.
Further, the fixed cover is attached to the base body by a fixing means having no detaching means,
On the other hand, the removable cover is attached to the base body by the sealing means,
The gaming machine according to claim 1, wherein the electronic component to be inspected is attached to the detachable cover by a fixing means having no detaching means.

  In the above, the electronic component to be inspected is an electronic component that can be a target of fraudulent work, and it is necessary to perform fraud monitoring even after the control device is completed. Some are voluntarily specified in the machine industry. The electronic component to be inspected at this time is a ROM in which a game program is recorded.

  According to the first aspect of the present invention, since the inspection target electronic component is attached to the cover body by the fixing means having no detaching means, the inspection target electronic component cannot be removed unless the cover body is broken. Therefore, since it is not possible to obtain an intact cover body that is necessary for disguising the replacement of an electronic component to be inspected with a tampered product, such a tampering can be prevented, and even if such a tampering is performed, a cover is provided. You can easily find it just by looking at your body.

Further, according to the invention described in claim 2, even if an unauthorized person illegally releases the sealing means, only the removable cover is removed, and the fixed cover is not removed. In addition, the fixed cover is attached by a fixing means that does not have a detaching means, such as a fitting connection that cannot be removed from the outside, tightening with a one-way screw, bonding with an adhesive, or heat welding. In order to do this, it is necessary to destroy the fixed part.
Therefore, when an unauthorized person tries to replace the entire control board with an illegally modified product, it is necessary to overcome the double hurdle of unsealing the removable cover and destroying the fixed cover. Therefore, there is an effect of suppressing such illegal acts and an effect that can be detected easily and quickly even if fraud is performed.

It cannot be removed unless the outside of the side frame members 20a and 20c is destroyed.

[Cover body ... Removable cover]
The detachable cover 23 covers the area 15 provided with the ROM 90 which is the electronic component to be inspected on the control board 10, and is aligned with the lateral dent of the fixed cover 22 as shown in FIGS. A detachable main plate 29 positioned at the same level as the rear surface member 24 of the fixed cover 22, a peripheral wall 30 surrounding the detachable main plate 29, and sealing means 14 disposed orthogonal to the detachable main plate 29, And the attachment piece 11 for attachment to the mechanism panel 3, and has a cross shape as a whole.

[Removable cover: Sealing means]
The sealing means 14 joins and seals the base body 17 and the detachable cover 23, and destroys a part of the base body 17 and the detachable cover 23 when releasing the seal. As shown in FIGS. 2 and 6 to 9, the sealing means 14 of the embodiment includes the sealing box 21 projecting from the base body 17 (the sealing box 21 is located above and below the side frame member 20 b as described above. Although the two sealing boxes 21 have a substantially vertically symmetrical structure, only one sealing box 21 will be described. The same shall apply hereinafter.) And so that the sealing box 21 is fitted. A sealing cover portion 31 formed on the detachable cover 23, a square hole-shaped sealing hole 32 formed in the sealing cover portion 31, and a communication hole 33 communicating from the inner part of the sealing hole 32 to the sealing box 21. The metal anchor rivet 34 attached to the communication hole 33 from the sealing hole 32 side, the one-way screw 35 screwed into the center of the anchor rivet 34 from the sealing hole 32 side, and the sealing hole 32 are closed. The mark cap 36 and the expected fracture line set so as to surround the sealing hole 32 (see the broken line in FIG. 9). However, this broken line is not engraved in the actual sealing cover portion 31 or the sealing box 21. It is an imaginary line indicating the breaking direction to the last.) Breaking holes 37, 37... The break opening 37 provided in the sealing cover part 31 is closed by a lid cover 38 that is formed in a triangular cap shape and is integrally formed with the sealing cover part 31, and this lid cover 38 is shown in FIG. It is designed to be used after being broken. Therefore, when the lid cover 38 of the sealing cover portion 31 is viewed, the state of the sealing means 14 can be confirmed at a glance.
The sealing means 14 described above corresponds to one in which the joint between the detachable cover 23 and the fixed cover 22 is stamped with “1”, and another corresponding to “2” in the circle.

  The sealing means 14 configured as described above fits the sealing cover portion 31 of the detachable cover 23 into the sealing box 21 of the base body 17, and the one-way screw 35 in the sealing hole 32 corresponding to “1” of the round enclosure. 8, the end portion of the anchor rivet 34 is expanded in diameter as shown in FIG. 8, and the sealing box 21 and the sealing cover portion 31 are joined by the force, and the sealing cap 36 is fitted into the sealing hole 32 in this state. If it is closed, the sealing cap 36 will not be fitted and removed, so that it will not even be possible to touch the one-way screw 35.

On the other hand, when releasing the sealing by the sealing means 14, as shown in FIG. 9, the two cover covers 38 sandwiching the sealing hole 32 corresponding to the circled "1" are broken with a tool such as a nipper. The breaking opening 37 is opened, and the cutting edge of the tool is inserted into the breaking opening 37 to break the sealing cover portion 31 and the sealing box 21 along the planned breaking line. As a result, the periphery of the sealing hole 32 where the sealing cover portion 31 and the sealing box 21 are joined is cut into an island shape. Therefore, when the detachable cover 23 is pulled backward, the detachable cover remains around the sealing hole 32. Only 23 comes off.
Since the seal means 14 remains engraved with “2” in the circle as described above, it can be sealed again by attaching the detachable cover 23 to the seal box 21.

  When the detachable cover 23 is removed from the base body 17, the area 15 provided with the ROM 90 of the circuit board 13 is exposed to the outside, but the other areas are surrounded by the peripheral frame members 25a to 25d. There is almost no risk of unauthorized manipulation of the component 9.

In the control device 7 of the embodiment described so far, even if an unauthorized person illegally releases the sealing means 14, only the detachable cover 23 is removed, and the fixed cover 22 is not removed. Further, since the fixing cover 22 is attached by fixing means having no removing means, it is necessary to destroy the fixing means in order to remove this.
Therefore, when an unauthorized person attempts to replace the entire control board 10 with an illegally modified product, it is necessary to overcome the double hurdles of releasing the seal of the removable cover 23 and destroying the fixed cover 22, and the traces are attached to the removable cover 23. And the fixed cover 22, it is difficult to perform such fraud, and even if it is done, it can be detected easily and quickly.

11 and 12 show other forms of fixing means for the fixed cover 22. In this embodiment, the sealing member (for example, the one-way screw 35 and the anchor rivet 34) remaining on the base body 17 side when the sealing means 14 is released is also used as a fixing means for the fixing cover 22. Therefore, as shown in FIGS. 11 and 12, the fixed cover 22 has a through hole 39 located between the sealing box 21 and the sealing cover portion 31 and communicating with the communication hole 33 of the sealing hole 32. A piece 40 is provided.
In this form of the substrate box 8, the fixed cover 22 is attached to the base body 17, then the detachable cover 23 is attached to the base body 17, and finally the sealing is performed by the sealing means 14 corresponding to “1” of the round enclosure. Then, the fixing cover 22 and the detachable cover 23 are fixed together by the sealing means 14, and even when the sealing means 14 is released, the fixing cover 22 is continuously fixed by the sealing member remaining on the base body 17 side. There is no need to separately provide fixing means for the cover 22.

In addition, the control apparatus of FIG. 11, FIG. 12 is grasped | ascertained as the following technical means.
[Technical means]
It has a control device that houses the control board in the board box,
The board box is
The base body located on the front side when the side close to the player in the installed state is `` front '' and the opposite side is `` rear '',
A transparent cover body that covers the rear side of the base body and is formed in a front opening shape by surrounding the periphery of the rear surface member facing the base body with a peripheral frame member;
Sealing with a sealing member in a state where the base body and the cover body are joined, and a sealing means that requires destruction of the base body or the cover body or self when releasing the seal,
The control board is
A circuit board attached to the inside of the board box;
In a gaming machine having a plurality of electronic components including at least one electronic component to be inspected mounted on the circuit board,
The control board arranges the electronic component to be inspected in a region of the circuit board on the side facing the portion where the sealing means of the cover body is provided,
The cover body is
The control board is divided into a detachable cover that covers the area where the electronic components to be inspected are provided, and a fixed cover that covers the other area of the control board.
The fixing cover is provided by a fixing means that does not have a detaching means with respect to the base body while providing the peripheral frame member at a portion along the detachable cover,
The removable cover is attached to the base body by the sealing means,
Furthermore, the sealing means is the one that the sealing member is separated and remains on the base body due to the destruction of the sealing release,
On the other hand, the fixing means is fixed by a sealing member of the sealing means.

Thus, as shown in FIGS. 4 and 5, in the control device 7 of the embodiment, the ROM 90 as the electronic component to be inspected is attached to the detachable cover 23 by a fixing means having no removing means.
That is, the fixing means of the ROM 90 shown in FIGS. 4 and 5 includes a semi-long hole-shaped engagement notch 41a formed on the left and right side surfaces of the ROM 90, and the attachment / detachment cover 23 so as to pass through the engagement notch 41a. The fixing pin 41b is driven into the peripheral wall 30 so as not to be pulled out. The ROM 90 fixed to the detachable cover 23 by the fixing means (engagement notch 41a, fixing pin 41b) is in a state of being integrated in the detachable cover 23 integrally with the detachable cover 23 as shown by a broken line in FIG. Unless it is destroyed. Therefore, since an intact detachable cover 23 necessary for skillfully disguising the replacement with the illegally modified ROM cannot be obtained, such an unauthorized operation can be prevented, and even if such an unauthorized operation is performed, the removable cover 23 can be prevented. You can easily find it just by looking at the
The fixing means for fixing the ROM 90 to the detachable cover 23 includes, other than the above, a fitting connection that combines a claw and a notch, tightening with a one-way screw, or heat welding.

  The removable cover 23 is formed with a through hole 91 as an electronic component pressing means for applying a pressing force to the built-in ROM 90 from outside, and a pin or the like is inserted into the through hole 91 from the outside of the removable cover 23. By pressing the ROM 90, the ROM 90 can be securely attached to the ROM socket 16.

  13 provides means for further improving the crime prevention performance of the embodiment. The gap between the inner surface of the removable main plate 29 of the removable cover 23 and the top of the ROM 90 is defined between the ROM 90 and the ROM socket 16. This is smaller than the mounting thickness of the illegal chip that can be mounted between them.

That is, in the control device 7 shown in FIG. 13, the mounting thickness of the illegal chip that can be mounted between the ROM 90 and the ROM socket 16 in the gap between the inner surface of the removable main plate 29 of the removable cover 23 and the top of the ROM 90. It is designed to be smaller. The mounting thickness of the illegal chip refers to a height protruding from the ROM socket 16 in a state where the illegal chip is incorporated in the ROM socket 16.
In order to set such a gap, the detachable cover 23 may be formed in accordance with the dimensions of the ROM 90. However, when the gap is small, high accuracy is required and the cost is high, and the design of the ROM 90 is changed. May become difficult. 13 forms a stepped hole 42 in which the large diameter portion and the small diameter portion are continuous in the detachable main plate 29 of the detachable cover 23, and the end is passed through the stepped hole 42 through a metal adjusting pin 43. In this state, the stepped hole 42 is filled with the adhesive 44 and hardened so that the gap between the ROM 90 and the removable main plate 29 is set to the most preferable “0”. .
According to this control device 7, since the detachable cover 23 is not normally mounted when an unauthorized chip is interposed between the ROM 90 and the ROM socket 16, it is possible to detect fraud at a glance.
The control device 7 in FIG. 13 may be applied to a cover body having a single structure that is not divided into the fixed cover 22 and the detachable cover 23.

  1 to 3, reference numeral 45 is a symbol display portion provided on the detachable cover 23, and the same symbol is attached to the symbol display portion 45 and the symbol display portion 46 provided to the fixed cover 22. Even if the fixed cover 22 and the detachable cover 23 obtained illegally separately are combined, they can be easily found.

As mentioned above, although embodiment of this invention was described, of course, this invention is not limited to the said embodiment. For example, in the embodiment, the base body 17 and a part of the detachable cover 23 are destroyed as the sealing means 14, but the seal may be released by destroying itself, for example, a sealing seal.
In the embodiment, the cover body 18 is divided into the fixed cover 22 and the detachable cover 23. However, the fixed cover 22 and the detachable cover 23 may be integrated.
In addition, although a pachinko machine has been exemplified as a gaming machine, it can be similarly applied to a slot machine and other gaming machines.
Further, the region 15 where the inspection target electronic component is provided may be provided near the corner of the circuit board 13 in addition to the case where the area 15 is provided near the center of one side of the circuit board 13 as in the embodiment.
