Hereinafter, preferred embodiments of a gaming machine substrate case according to the present invention will be described with reference to the drawings.
There are various types of gaming machines such as pachinko machines, slot machines, arrangement balls, and sparrow balls. In this embodiment, the board case for gaming machines of the present invention is applied to a slot machine that uses medals as gaming media. The case will be described.

[Slot Machine]
As shown in FIG. 1, the slot machine 100 constitutes a spinning-reel type gaming machine that can acquire medals as game media by rotating a plurality of reels 110a, 110b, and 100c.
The slot machine 100 includes a casing 100b that opens on the front side for housing necessary machines, devices, and the like, and a front door 100a that covers the front side of the casing 100b so as to be opened and closed.
The front door 100a is a door body that is attached to the housing 100b through a hinge or the like so as to be opened and closed. The front door 100a starts a rotation of each reel 110 and stops each rotating reel 110. A plurality of operation means such as three stop buttons are provided to constitute the front portion of the slot machine 100.

In the center of the housing 100b, reels 110a, 110b, and 110c, a motor (not shown) that rotatably supports each reel 110, a sensor that detects a rotational position, and the like are provided.
In addition, a medal payout device 120 for storing and paying out medals is provided at the lower part of the housing 100b.
A substrate case 1 in which a predetermined printed circuit board is accommodated is provided on the top of the housing 100b.

  The board case 1 is an example of a board case for gaming machines according to the present invention, and controls each device such as each reel 110 and the medal payout device 120 based on the signals from the respective operation means, thereby enabling slot machine gaming. The so-called main substrate 2 that controls the progress of the above is accommodated.

The slot machine 100 configured as described above is controlled by the main board 2 as follows, and the slot machine game proceeds.
First, when a player inserts a medal and the start lever is operated, the main board 2 performs control to rotate each reel 110 and performs internal lottery to draw bonuses, small roles, etc., and each stop button Based on the timing at which is pressed, stop control of each rotating reel 110 is performed so as to stop at a combination of symbols according to the lottery result.

  Further, the main board 2 determines a combination of symbols to be stopped and displayed on each reel 110, and controls the medal payout device 120 to pay out a predetermined number of medals when the predetermined combination of symbols is obtained.

The main board 2 that controls the progress of such a slot machine game includes various means such as a CPU (Central Processing Unit), storage means such as ROM and RAM, IC components such as an I / O interface, resistors, capacitors, and transistors. The printed circuit board includes a component mounting surface 2a on which electronic components are mounted and a solder surface 2b for soldering the lead portions of these components (see FIG. 2).
The main board 2, for example, rewrites the contents of the program stored in the ROM, or replaces the mounted electronic parts with different electronic parts, so that the gaming characteristics (for example, the play rate) in the slot machine 100 Since it can be easily changed, the board is highly likely to be tampered with.

Therefore, as shown in FIGS. 2 and 5, the substrate case 1 of the present embodiment accommodates the main substrate 2 sandwiched between the lid case 3 and the main body case 4, and by predetermined caulking structures 30 and 40, It is sealed so that it cannot be opened. Furthermore, the substrate case 1 includes a seal 7 and a cover 8 that are pasted across the cases 3 and 4. The cover 8 not only covers the seal sticking surfaces 310 and 410a but also has a function of sealing the two cases so that they cannot be opened.
Hereinafter, the configuration of the substrate case 1 of the present embodiment will be described with reference to FIGS.

[Board case]
As shown in each drawing, the substrate case 1 has a rectangular case structure, and includes a lid case 3 that covers the component mounting surface 2a side of the main substrate 2 and a main body case 4 that covers the solder surface 2b side. .
In the present embodiment, the main board 2 is accommodated by being screwed into the lid case 3 with a predetermined screw (see FIG. 2).
The lid case 3 and the main body case 4 are made of a colorless and transparent industrial resin (for example, polycarbonate) so that the component mounting surface 2a and the solder surface 2b can be visually recognized from the outside and cannot be easily broken.
The substrate case 1 also includes a hinge 1a that supports the lid case 3 and the main body case 4 so as to be opened and closed. The hinge 1a is configured such that, when the case is closed, the lid case 3 and the main body case 4 are pivoted so that the case cannot be opened from the hinge 1a side.
The substrate case 1 has a housing in which the body case 4 side faces the back of the housing 100b and the lid case 3 side faces the front opening of the housing 100b, that is, the component mounting surface 2a can be seen from the front. 100b.

The substrate case 1 has a caulking structure that seals the lid case 3 and the main body case 4 so that they cannot be opened.
Specifically, as shown in FIGS. 2 and 5, the caulking structure includes a lid caulking portion 30 formed in the lid case 3, a main body caulking portion 40 formed in the main body case 4, and a caulking pin 5. When the lid case 3 and the body case 4 are closed and the caulking pin 5 is inserted from the insertion port 40a (see FIG. 2), the caulking pin 5 is inserted over the caulking portions 30 and 40 and is removed. The lid case 3 and the main body case 4 are sealed so as not to be opened by being attached so that they cannot be removed (see FIG. 5).

The substrate case 1 also includes a sealing seal 7 that seals the lid case 3 and the main body case 4 so that they cannot be opened.
The seal seal 7 is an example of the seal member of the present invention. As shown in FIG. 5 or FIG. 10B, a QR code 7a indicating unique ID information is printed on the surface and this ID information is recorded. A predetermined adhesive is applied to the passive type IC tag 7b and the antenna 7c that receives the radio wave from the tag reader to generate power and generates the IC tag 7b and conveys ID information to the reflected wave and transmits it to the tag reader. It is arranged on the back side.
If this seal seal 7 is peeled off, the antenna 7c is broken and the radio wave from the tag reader cannot be received or the ID information cannot be transmitted. That is, the tag reader cannot easily read the ID information. It is made of fragile paper. Therefore, a seal sticking surface for sticking the seal seal 7 across the lid case 3 and the main body case 4 is provided so that the ID information cannot be read when the substrate case 1 is opened.

The seal sticking surface includes a lid flange portion 31 and a main body flange portion 41 formed in the lid case 3 and the main body case 4.
Specifically, the lid case 3 and the main body case 4 are respectively formed with a lid flange portion 31 and a main body flange portion 41 that project substantially parallel to the main substrate 2 accommodated from the outer edge of the case.
The main body flange portion 41 is a rectangular convex portion protruding from the outer edge on the opposite side of the hinge portion 1a, and the upper surface thereof has a main body flange surface 410b corresponding to a portion overlapping the lid flange portion 31 when the case is closed, A main body flange surface 410a is formed which does not overlap with the lid flange portion 31 but is exposed to the outside.
The lid flange portion 31 protrudes from the outer edge on the opposite side of the hinge portion 1a and is formed in a substantially U shape so as to cover the main body flange surface 410b when the case is closed, and on the upper surface thereof, the main body flange surface 410a when the case is closed A lid flange surface 310 is formed which is flush with the surface.
As shown in FIG. 5, the seal sticking surface is composed of a lid flange surface 310 and a main body flange surface 410a when the case is closed.

By configuring the seal sticking surface in this manner, the seal seal 7 does not hinder the visibility of the main substrate 2, and the seal seal 7 and the main substrate 2 are substantially parallel. When the front door 100a is open, the seal seal 7 faces the front, and the presence or absence of peeling of the seal seal 7 can be easily confirmed.
Moreover, the seal sticking surface is arrange | positioned on the opposite side of the hinge part 1a. Thereby, even if the substrate case 1 is slightly opened, an external force is applied to the seal seal 7 and it is broken, so that a trace of opening can be reliably left.

Further, screw holes 311 and 411 are formed in the lid flange portion 31 and the main body flange portion 41 so as to be inserted when the case is closed, and the screws 6 are screwed into the screw holes 311 and 411 as shown in FIG. By inserting, the cover flange part 31 and the main body flange part 41 can be screwed together, and the cover case 3 and the main body case 4 can be sealed (see FIG. 10A).
Further, the screw holes 311 and 411 are provided at positions corresponding to the IC tag 7b of the seal 7 to be affixed (see FIG. 10B). In order to open the lid case 3 and the main body case 4, it is necessary to remove the screw 6. Therefore, a driver must be inserted into the portion of the IC tag 7 b. As a result, the IC tag 7b is destroyed and the unique ID information cannot be read, so that the trace of opening can be reliably left.

Furthermore, the substrate case 1 of the present embodiment includes a cover 8 that covers the seal sticking surface and is attached to the main body case 4 so as not to be detached.
The cover 8 is an example of a cover member of the present invention, and is formed of a transparent industrial resin material (for example, polycarbonate), and is configured to protect the attached seal seal 7 so as to be visible and not peelable. ing. The cover 8 of the present embodiment will be described below with reference to FIGS.

  As shown in FIGS. 6A to 6C, the cover 8 is formed in a substantially L shape, and when attached to the main body case 4, the cover flange surface 310 and the main body flange surface whose upper surface is in the case closed state. The seal seal 7 is covered by facing 410a (see FIGS. 5 and 10C).

The cover 8 includes a claw portion 83 that is locked to the main body case 4.
A locking hole 413 and a tongue piece 414 are formed in the main body case 4 (see FIG. 7), and the cover 8 is locked to the main body case 4 so as not to be detached by inserting the claw portion 83 into the locking hole 413. It has come to be.
Specifically, the claw portion 83 includes an outer claw 83a and an inner claw 83b, and has a wedge shape in which both sides are formed in a hook shape. By inserting the claw portion 83 into the locking hole 413, the outer claw 83a is locked to the bottom surface of the main body case 4 and the inner claw 83b is locked to the bottom surface of the tongue piece 414 as shown in FIG.
By forming the claw portion 83 in a wedge shape in this way, insertion and locking of the claw portion 83 into the locking hole 413 can be performed by elastic deformation of the claw portion 83 and the tongue piece 414. From the stopped state, unless the external force is simultaneously applied to the claw portion 83 and the tongue piece 414 to be deformed, it can be made unremovable.

  However, as shown in FIG. 8, the concave portion 41 a which is the bottom surface of the main body flange portion 41 is in a state where the claw portion 83 and the tongue piece 414 are exposed, and by applying an external force to these, the claw portion 83 is locked. It will be released. Therefore, as shown in FIG. 9, the claw portion 83 and the tongue piece 414 are made inoperable by fixing (adhering) the shield plate 9, which is an example of the shield means, to the recess 41 a so as not to be removed (FIG. 9). reference). Thereby, since an external force cannot be applied to the claw part 83 and the tongue piece 414, the cover 8 is locked to the main body case 4 so as not to be detached.

In this way, the cover 8 is locked to the main body case 4 so as not to be detached, so that the cover 8 not only protects the sealing seal 7 from being peelable but also seals the lid case 3 and the main body case 4 so that they cannot be opened. Acts to stop.
This is because the cover 8 has a cover flange cover portion 8a corresponding to a portion covering the cover flange surface 310 (see FIG. 6A). That is, since the cover flange cover portion 8a covers the cover flange surface 310, when the cover 8 is detachably locked to the main body case 4, the cover flange cover portion 8a restricts the movement of the cover flange 31, It acts to prevent the lid case 3 from being opened.
As described above, the cover flange surface 310 and the main body flange surface 410a form a seal application surface, and the cover 8 covers the seal application surface and is locked to the main body case 4 so as not to be detached. Not only protects the seal seal 7 so that it cannot be peeled off, but also seals the lid case 3 and the main body case 4 so that they cannot be opened, and has the same effect as the caulking structures 30, 40.

Further, as shown in FIG. 6A, the cover 8 includes a cover flange cover portion 8a corresponding to a portion covering the cover flange surface 310, and a removal portion corresponding to a portion locked to the body case 4 so as not to be detached. The non-separable portion 8b is arranged with the line B divided into boundaries.
By disposing the cover 8 along the line B and detaching the cover flange cover part 8a from the non-detachable part 8b, the cover flange 31 covered by the cover flange cover part 8a is removed from the outside. (See FIG. 12). Thereby, the board | substrate case 1 can also be open | released by peeling the sealing seal | sticker 7 and removing the screw | thread 6. FIG.
Even in this case, since the non-detachable portion 8b is locked to the main body case 4 so as not to be removable, it is possible to clearly leave a trace of opening.

Furthermore, as shown in FIG.6 (c), the seal | sticker holding | suppressing part 84 which presses the affixed sealing seal 7 from upper direction is formed in the non-detachable part 8b.
The seal pressing portion 84 is provided in a portion that covers the main body flange surface 410a that is a part of the sticking surface of the seal, protrudes toward the main body flange surface 410a, and presses the seal seal 7 from above.
Thus, the seal seal 7 can be peeled off when the cover flange cover portion 8a is removed and the cover flange 31 is exposed to the outside, but the seal seal 7 is narrowly formed between the seal pressing portion 84 and the main body flange surface 410a. Since it is held, the seal seal 7 is peeled off with the nipped portion remaining. Thereby, the trace from which the seal seal 7 was peeled can be clearly left.

The cover 8 is provided with a convex portion 81 and a hole 82 along the line B so that the cover 8 can be easily divided into the cover flange cover portion 8a and the non-detachable portion 8b.
The convex portion 81 is formed so as to protrude upward from the upper surface of the cover 8, and a groove 81a is provided therein.
Thereby, when a cutter such as a cutter or nipper is slid parallel to the upper surface of the cover 8 and the convex portion 81 is pruned, the convex portion 81 becomes a hole, and further, the pruning is performed so that the hole and the hole 82 are connected. The cover 8 can be divided along the line B. Thereby, when confirming the presence or absence of unauthorized modification to the main board 2, it is possible to improve workability when the board case 1 is legally opened.

The attachment of the cover 8 configured as described above to the substrate case 1 and the operation of dividing the cover 8 will be described with reference to FIGS.
First, when the main board 2 is attached to the lid case 3 and the lid case 3 and the body case 4 are closed via the hinge 1a, as shown in FIG. 10A, the lid flange surface 310 and the body flange surface The same sticking surface with 410a is formed. Further, the screw 6 is screwed into the screw holes 311 and 411, and the lid flange portion 31 and the main body flange portion 41 are screwed together. Then, as shown in FIG. 10B, a seal seal 7 is affixed to the seal affixing surface.

At both ends of the lid flange surface 310, rib-like seal enclosures 312 projecting upward are provided. The seal enclosure 312 is formed higher than the thickness of the seal seal 7 and functions as a guide rib when the seal seal 7 is affixed, and prevents insertion of a blade (such as a cutter) between the seal seal 7 and the seal application surface. It also has a function to
As shown in FIG. 13, not only the lid flange surface 310 but also the main body flange surface 410a is provided with a seal enclosure 412, and the seal enclosures 312 and 412 are disposed on the entire circumference of the lid flange surface 310 and the main body flange surface 410a. It can also be provided. Thereby, insertion of a blade (a cutter etc.) can be blocked from the entire circumference.
Furthermore, as shown in the figure, a urethane material 10 made of a urethane resin adhesive that hardens when two liquids are mixed is filled in the seal enclosures 312 and 412, and the adhered seal seal 7 is coated with the urethane material 10. You can also
As a result, the seal seal 7 is entirely covered with the urethane material 10 and cannot be peeled off from the sticking surface of the seal, so that the seal seal 7 can be protected more firmly.
Further, in this case, the urethane material 10 may be filled between the cover 8 and the seal seal 7 and the cover 8 may be bonded to the seal application surface.

And the cover 8 can be attached to the main body case 4 as shown in FIG.10 (c) by inserting the nail | claw part 83 in the latching hole 413. As shown in FIG. Thereby, the cover 8 is locked to the main body case 4 so as not to be detached, and the seal seal 7 can be covered so as not to be peeled off.
The convex portion 81 and the hole 82 are arranged so as to ensure the visibility of the QR code 7a in this state.

The cover 8 is divided as follows.
First, a cutter such as a cutter or a nipper is slid in parallel with the upper surface of the cover 8 to trim the convex portion 81. Thereby, since the groove | channel 81a is formed inside the convex part 81, the convex part 81 becomes a hole as shown to Fig.11 (a). Further, when this hole is trimmed so as to connect the hole 82, the cover 8 can be divided along the line B as shown in FIG.

When the cover flange cover portion 8a is removed in this state, the seal seal 7 corresponding to the cover flange surface 310 can be exposed to the outside as shown in FIG.
Since the seal seal 7 cannot be peeled by preventing the blade from being inserted by the seal enclosure 312 and being held by the seal pressing portion 84, a corresponding cut between the lid flange surface 310 and the main body flange surface 410a. A cutting tool is inserted along the line 7d to cut the seal seal 7.
Further, the screwdriver 6 is pierced through a portion corresponding to the screw hole 311 of the seal seal 7 with a screwdriver, and the screw 6 is removed to unscrew the cover flange portion 31 and the main body flange portion 41 and open the substrate case 1. Can do. At this time, since the IC tag 7b is disposed at a portion corresponding to the screw hole 311, the IC tag 7b is surely destroyed by the driver and cannot be read by the tag reader.
Thus, in order to open the substrate case 1, not only the cover 8 is broken, but also the sealing seal 7 is cut and the IC tag 7 b is broken, so that a trace of opening remains reliably. .

  As described above, according to the substrate case 1 according to the present embodiment, the seal seal 7 is protected so as not to be peeled off, and when opened, the trace is reliably left to improve security against unauthorized modification. be able to.

  As mentioned above, although the preferred embodiment was shown and demonstrated about the board case for game machines of this invention, the board case for game machines which concerns on this invention is not limited only to embodiment mentioned above, The range of this invention Needless to say, various modifications can be made.

For example, in the present embodiment, the printed circuit board accommodated in the substrate case 1 is the main substrate, but it is also possible to accommodate sub-substrates or other substrates that are effect substrates for controlling speakers, lamps, and the like.
In this embodiment, the coating material for coating the attached seal seal 7 is the urethane material 10 (urethane resin-based adhesive). However, synthetic adhesives such as acrylic resin-based adhesives and epoxy resin-based adhesives are used. Can also be used.
In the present embodiment, the printed circuit board (main board 2) is fixed to the lid case 3, but it can also be fixed to the main body case 4.
