Description

  The present invention relates to a gaming machine board case comprising a gaming control board that controls a gaming machine that gives a player a specific gaming value in accordance with a game, a board base that houses the gaming control board, and a board cover. It is about.

  Conventionally, a gaming machine such as a pachinko machine has been provided with a game control board that controls a game content including a central processing unit (hereinafter referred to as a CPU), a storage element (hereinafter referred to as a ROM), and the like. The substrate is housed in a synthetic resin substrate case composed of a substrate base and a substrate cover in order to protect against contact with other conductive parts, impacts, etc., and is disposed on the back surface of the gaming machine. This game control board has its game operation controlled based on the game control program stored in the ROM. Depending on the content of the game control program (probability of becoming a special game state called a big hit, etc.) Profits for players are affected. For this reason, it is possible to replace the ROM storing the normal game program of the game control board with the ROM storing the illegal game program in which the probability of entering the special game state is changed when the game store is not operating from outside. In some cases, an illegal act of illegally generating a special gaming state and obtaining a game is performed. In order to prevent this, the board case for storing the game control board is provided with sealing means for making it impossible to remove the board cover.

  The sealing means makes it impossible to remove the substrate cover from the substrate base by assembling the substrate base and the substrate cover with screws that can be rotated only in one direction, so-called one-way screws.

However, since there is a high possibility that a fraudulent act is performed by an act such as cutting the sealing means or opening the substrate case, an invention for preventing fraud using an IC tag has been made in recent years.
Further, as an invention for preventing fraud using the IC tag, a tape-type inlet containing an IC chip and an antenna is stuck across the substrate base and the substrate cover, and is peeled off, torn, cut, etc. The proposal has been made to detect fraud early because the antenna is disconnected due to the act of [1] and the ID cannot be read.
The following patent documents can be cited as inventions for preventing fraud using an IC tag.

  Next, the configuration of the substrate case 47, which is the gist of the present invention, will be described with reference to FIGS. 3 is a perspective view of the substrate case 47, and FIG. 4 is an exploded perspective view thereof. As shown in FIG. 3, the substrate case 47 includes a substrate base 56 for placing the main control substrate 46, a substrate cover 57 that covers and protects the main control substrate 46 from above the substrate base 56, and a substrate It comprises sealing members 58 to 61 for making it impossible to remove the substrate cover 57 projecting at two positions above and below the left side of the case 47, a spacer 62 described later, and the like. Further, the substrate base 56, the substrate cover 57, the sealing members 58 to 61 and the like constituting the substrate case 47 are formed of a permeable synthetic resin so that the inside can be seen through.

  Next, each component of the substrate case 47 will be described in detail with reference to FIG. As described above, the substrate case 47 includes the substrate base 56, the substrate cover 57, the sealing members 58 to 61, and the like. The sealing members 58 to 61 are provided on the left side surface of the substrate cover 57, and are provided with first tube portions 58 b to 61 b connected by first connection portions 58 a to 61 a protruding from the left side surface of the substrate cover 57.

The left side surface of the substrate base 56 is provided with second cylindrical portions 58e to 61e connected by second connecting portions 58d to 61d protruding from the left side surface of the substrate base 56. The second cylindrical portions 58e to 61e contain screw hole members 58f to 61f having screw holes into which the screws 58c to 61c described above can be inserted.

  Here, the main control board 46 accommodated in the board case 47 will be described with reference to FIG. As shown in FIG. 5, the main control board 46 is formed of a rectangular printed wiring board, and most of the upper surface thereof is formed as an electronic component mounting area 67 for mounting an electronic component 66 such as a ROM. A region on one side in the width direction is formed as a connector mounting region 69 for mounting the connector 68. Further, stop holes 70 and 70 and engagement holes 71 and 71 are formed at four corner portions of the main control board 46.

  As shown in FIG. 4, the substrate base 56 is formed with a main control board placement region 73 for placing the main control board 46 surrounded by guide ribs 72. Protrusions 72a and 72b and screw holes 72c and 72d for positioning and screwing the main control board 46 are provided at the inner corners of the guide ribs 72 of the main control board placement region 73. The main control board 46 is placed so that the engagement holes 71 and 71 of the main control board 46 are inserted into 72b, screws are inserted into the stop holes 70 and 70 and screwed into the screw holes 72c and 72d, and the main control board 46 is inserted into the board base 56. Can be fixed to. An attachment portion 74 having an attachment hole 74 a for attaching the substrate case 47 to the mechanism plate 40 projects from the right side surface of the substrate base 56. The substrate case 47 can be attached to the mechanism plate 40 by inserting a screw or the like into the attachment hole 74a of the attachment portion 74 and fastening it. In the vicinity of the attachment portion 74, bearings 75 and 75 having shaft holes 75a and 75a for allowing the substrate cover 57 to be opened and closed are provided.

  The substrate cover 57 has a U-shape with an open bottom surface, and first cylindrical portions 58b to 61b connected by the first connecting portions 58a to 61a protrude from the left side surface thereof. Concave portions 76a and 76b are formed on the upper surface of the substrate cover 57, and are written in the concave portions 76a and 76b when the model name seal indicating the model name of the pachinko machine 10 and the main control board 46 are inspected. The inspection history sticker is pasted. Further, a covering member 77 projects from one side of the substrate cover 57 in the width direction. The covering member 77 has a rectangular shape, and a plurality of insertion holes 78 through which the connectors 68 arranged in parallel in the connector mounting area 69 of the main control board 46 are inserted. The right side surface of the substrate cover 57 is provided with support shafts 79 and 79 that serve as pivot shafts for supporting the substrate cover 57 so that the substrate cover 57 can be opened and closed, and the support shafts 79 and 79 are bearings provided on the substrate base 56. The substrate cover 57 can be supported so as to be openable and closable by being inserted into the shaft holes 75a and 75a of 75 and 75.

  Next, the sealing members 58 to 61 for making it impossible to remove the substrate cover 57 will be described in detail with reference to FIGS. In addition, since the structure of the sealing members 58-61 and the sealing method are all the same, here, the sealing member 58 is demonstrated as a representative example. 5 is an exploded perspective view in which the sealing member 58 is enlarged, and FIG. 6 is a perspective view in a state in which the sealing member 58 is sealed. As shown in FIG. 5, the sealing member 58 includes a first tube portion 58b connected by a first connecting portion 58a extending from the left side surface of the substrate cover 57, a screw 58c temporarily fixed therein, and a substrate. The second cylindrical portion 58e is connected by a second connecting portion 58d extending from the left side of the base 56, and a screw hole member 58f is included in the second cylindrical portion 58e.

  Subsequently, these components will be described in detail. First, the first tube portion 58b has a columnar shape, and a columnar opening 58g is formed therein. An insertion hole 58h through which the screw 58c can be inserted is opened on the bottom surface of the opening 58g. When the sealing member 58 is not sealed, the screw 58c is temporarily fixed to the insertion hole 58h.

  The screw 58c is a so-called one-way screw, and the one-way screw 58c will be described here. The one-way screw 58c is a special screw that rotates only in the screw tightening direction, and once tightened, it cannot be removed unless the screw is destroyed. Specifically, as shown in FIGS. 8A and 8B, the screw groove provided in the head 80 includes a contact surface portion 81, a recessed portion 82, and a center hole portion 83. When the screw 58c is tightened with the special minus driver 84 shown in FIG. 9C, the center shaft portion 85 of the minus driver 84 is inserted into the center hole 83, and the contact piece of the minus driver 84 from this state. The screw portion 58 is brought into contact with the contact surface portion 81 and the head portion 80 is rotated in one direction (clockwise direction in FIG. 8A) to tighten the screw 58c. On the other hand, when the head screw 80 is rotated in the other direction (counterclockwise direction in FIG. 8A) by the minus driver 84 and the screw 58c is to be removed, the minus driver 84 enters the recess 82 and slides. As a result, the head 80 cannot be rotated and the screw 85c cannot be removed. It is possible to tighten the screw 58c by rotating the head 80 in one direction even with a normal minus driver, but like the special minus driver 84, the center shaft portion 85 is inserted into the center hole 83 of the screw 58c. Thus, the tightening operation can be easily performed by positioning with the screw 58c.

  It is also conceivable to use a so-called breaking screw instead of the one-way screw as described above. This breaking screw can be rotated in the tightening direction, but when the screw is rotated in the loosening direction, the head of the screw is broken and cannot be loosened. Even if such a screw is used, the same effect as that of the one-way screw can be obtained.

  The outer peripheral edge portion of the first cylinder portion formed as described above and the left side surface of the substrate cover 57 are connected to each other so as to be integrally formed with the first connection portion 58a. The second cylindrical portion 58e has a cylindrical shape having an opening 58i on the lower surface, and an insertion hole 58j into which the screw 58c described above can be inserted is opened on the upper surface. And the screw hole member 58f in which the screw hole 58k is formed is enclosed in the opening part 58i of this 2nd cylinder part 58e. On the lower surface of the screw hole member 58f, two locking portions 58l and 58l having fan-shaped shapes that become gradually inclined downward as they proceed in the clockwise direction protrude at two symmetrical positions. Further, on the upper surface of the second connecting portion, two locking portions 58m, 58m having fan-shaped shapes whose upward inclination becomes tighter as they proceed in the counterclockwise direction protrude in two symmetrical positions. When these are assembled, the screw hole member 58f is enclosed in the opening 58i of the second cylindrical portion 58e, and then the upper surface of the second connecting portion 58d and the lower surface of the second cylindrical portion 58e are thermally welded. Assemble by. By doing in this way, screw hole member 58f can rotate in the opening part 58j of the 2nd cylinder part 58e, ie, can be included in a free state.

  Next, a sealing method of the sealing member 58 will be described with reference to FIG. First, the substrate cover 57 is attached to the substrate base 56, and it is confirmed that the lower surface of the first tube portion and the upper surface of the second tube portion are aligned. Then, as described in FIG. 8, the screw 58c is tightened with a special minus driver. When the screw 58c is tightened, the screw 58c is inserted into the insertion holes 58h and 58j and then tightened into the screw hole 58k of the screw hole member 58f. When the tip of the screw 58c is tightened in the screw hole 58k, the screw hole member 58f is rotatable, so that the screw hole member 58f is rotated. However, when the screw hole member 58f rotates to a position where the tips of the latching portions 58l and 58l projecting on the lower surface of the screw hole member 58f and the tips of the latching portions 58m and 58m projecting on the upper surface of the second connecting portion abut. In this position, the screw hole member 58f is locked and fixed so as not to rotate. As described above, when the screw hole member 58f is fixed in a non-rotatable manner, the screw 58c can be tightened and is tightened into the screw hole 58k of the screw hole member 58f. When the head of the screw 58c reaches the lower surface of the opening 58g of the first tube portion 58b, the screw 58c cannot be further tightened into the screw hole 58k. That is, the substrate cover 57 and the substrate base 56 can be sealed so that they cannot be removed.

  In this way, even if the self-made tool is used so that the screw 58c can be removed in an attempt to replace the ROM or the like of the main control board 46 illegally from the sealed state, the screw 58c is rotated in the loosening direction. The screw hole member 58f is idled by the locking portions 58l and 58l protruding from the lower surface of the hole member 58f and the locking portions 58m and 58m protruding from the upper surface of the second connecting portion 58d. More specifically, when the screw 58c is loosened, that is, rotated counterclockwise, the screw hole member 58f also tries to rotate counterclockwise. When the screw hole member 58f rotates in the counterclockwise direction, the inclination of the locking portions 58l and 58l increases the inclination of the locking portions 58m and 58m. That is, the screw hole member 58f is not fixed in a non-rotatable manner, and continues to idle. In short, even if the screw 58c is rotated in the loosening direction, the screw 58c does not loosen due to the idling of the screw hole member 58f. Therefore, the substrate case 47 cannot be opened. Therefore, when the substrate case 47 is opened, the first connecting portion 58a and the second connecting portion 58d must be cut. When sealing the substrate case 47, one of the sealing members 58 to 61 shown in FIG. 3, for example, the sealing means 58 and the sealing means 60, the sealing step 59 and the sealing means 61, etc. Seal as a pair on the left and right. Therefore, the substrate case 47 can be opened up to twice for inspection of the main control board 46 and the like. When the substrate case 47 is opened for the second time, the substrate case 47 is replaced with a new one.

As for the substrate case 47, a state where the spacer 62 is fitted to the substrate case 47 is shown in FIG. 9A, and a state before the fitting is shown in a partial perspective view of FIG. As illustrated, a tape-type inlet 63 is attached to the space 64 of the substrate case 47.
The tape-type inlet 63 of this embodiment is a general-purpose product and has an IC chip and an antenna built therein. A memory is built in the IC chip, and the memory includes a system area and a user area. The data written in the memory can be read by a reader / writer, but the system area cannot be rewritten, so the ID number unique to the IC chip written in the system area cannot be changed. . Therefore, forgery or copying is impossible.
The inlet has a shape of about 53 mm in length, 1.5 mm in width, and 0.25 mm in thickness.
The inlet is a thin film, and an acrylic resin adhesive is applied to the back surface thereof.

  FIG. 10 shows a case where visible printing is performed on the surface of the tape inlet. In this case, since it is difficult to recognize printing with a thin tape type inlet, a description will be given by taking a horizontally long tape type inlet 63a having a width of 10 mm as an example. (A) is an example in which the QR code (registered trademark) 100 is printed on the horizontally long tape type inlet 63a, and (b) is an example in which the serial number 101 is printed on the horizontally long tape type inlet 63a. As a result, if data such as the manufacturing date, manufacturer, manufacturing location, and manufacturing number can be recognized, even if the tape-type inlet is damaged and the data in the IC chip cannot be read, the minimum necessary information can be acquired.

A state in which the spacer 62 is fitted to the substrate case 47 is shown in FIG. 11A, and a state before the fitting is shown in a partial cross-sectional view in FIG.
The spacer 62 is formed of a permeable synthetic resin so that the state of the tape-type inlet 63 can be seen.
The spacer 62 is provided with a pair of locking pieces 102 and locking claws 103 at the tips of the locking pieces. When the spacer 62 is fitted into the space portion 64, the locking piece 102 is inserted into the locking hole 65 in the space portion 64, and when pressed, the locking claw 103 is engaged with the locking portion 104 on the back side of the substrate case. Get caught in. In this state, the spacer 62 is removed from the substrate case 47 unless the locking claw 103 is spread away from the locking portion 104 from the back side of the substrate case 47 and the locking portion 104 and the locking claw 103 are separated. It cannot be peeled off. That is, it is impossible to remove the spacer 62 while the board case 47 is fitted, except in a situation where the spacer 62 itself is damaged.
The spacer 62 fitted to the substrate case 47 is removed when the substrate cover 57 and the substrate base 56 constituting the substrate case 47 are separated from each other. The pair of locking claws 103 of the spacer 62 are sandwiched between fingers from the back side of the substrate case 47, and the locking claws 103 are shifted toward the locking holes 65 away from the locking portions 104 and pushed into the locking holes 65. The spacer 62 can be removed.
Further, by attaching a sheet-like radio wave absorber 105 made of ferrite or sandy magnetite having a thickness of about 0.5 mm to the back side of the substrate case 47, the communication state between the tape-type inlet and the reader is improved. The effect can be expected, and at the same time, the influence of electromagnetic waves emitted from the tape-type inlet or the reader on the electronic component 66 in the substrate case 47 can be suppressed.
