Description

  The present invention relates to a gaming machine board case in which a predetermined printed circuit board is accommodated, and in particular, increases the sealing force when the board case is squeezed to make it unopenable, and the caulking pins used for sealing are reused. The present invention relates to a board case for a gaming machine that has been made possible.

In general, a gaming machine such as a slot machine or a pachinko machine is provided with a plurality of boards involved in game performance.
These boards include a main board, which is a main board that controls the overall gaming machine as well as affects the outcome of the game.
The main board is configured as a computer in which various electronic components such as a CPU, a ROM, and a RAM are arranged on a printed board.
The main board that influences the outcome of such games is subject to unauthorized modification, and for this purpose, the main board is sandwiched between two transparent cases, and the case is sealed unopened. It has stopped.

The structure for sealing the substrate case is referred to as a caulking structure, and generally the case cannot be opened by locking the cases with a dedicated caulking pin or the like.
Many cases of such a caulking structure have been proposed in the past, such as "Control Device Case Sealing Device for Game Machines" (Patent Document 1) of Japanese Patent Application Laid-Open No. 2005-192792.

However, the conventional caulking structure has the following adverse effects.
In the caulking structure described in Patent Document 1, the caulking pin is inserted and locked over a plurality of openings, but the external force that opens the substrate case is in the same state as the cantilever. When the continuous external force is applied to the free end side, the caulking pin is bent and may fall off.

The normal caulking structure is designed to release the sealed state by cutting and destroying the caulking pins that lock the cases together with a cutting tool such as a nipper.
Since the substrate case may be opened for a legitimate purpose such as confirming unauthorized modification to the main substrate, a plurality of spare caulking pins for resealing are provided as in the invention described in Patent Document 1. ing.
However, since this spare caulking pin is set in advance in the substrate case, it may be forged by removing it. If counterfeit goods are put on the market, resealing can be easily performed, which may lead to fraud.

  The present invention has been proposed to solve the above-described problems, and is arranged so that the opening on one case side through which the caulking pin is inserted sandwiches the opening on the other case side, An object of the present invention is to provide a gaming machine substrate case that increases the sealing force against an external force to be opened and allows the caulking structure to be released without cutting or destroying the caulking pin so that the caulking pin can be reused.

  In order to achieve the above object, a board case for a gaming machine according to the present invention is for a gaming machine having a caulking structure that holds a predetermined printed circuit board between a lid case and a main body case and seals the lid so that it cannot be opened. The caulking structure is provided in each case and is opened substantially in parallel with the printed circuit board surface, and an opening through which a predetermined pin material can be inserted when the case is closed. A locking portion that locks the pin material inserted through the opening in a non-removable manner so that one case-side opening sandwiches the other case-side opening. The arrangement is arranged.

  According to the board case for gaming machines of the present invention, the forgery of the caulking pin is prevented by increasing the sealing force when the board case is caulked so that it cannot be opened and by reusing the caulking pin used for sealing. it can.

[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.

Accordingly, as shown in FIGS. 2 to 6, the substrate case 1 of the present embodiment accommodates the main substrate 2 between the lid case 3 and the main body case 4, and the predetermined caulking pins 5 are disposed in the lid case 3. And is engaged with the main body case 4 so that it cannot be opened.
The substrate case 1 can be unsealed without cutting and destroying the caulking pins 5, and can be resealed by reusing the caulking pins 5.
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 to 5, the caulking structure includes caulking pins 5 that engage with the lid case 3 and the main body case 4, and lid caulking that protrudes from the outer edges of the lid case 3 and the main body case 4. Provided in the part 30 and the caulking part 40 of the main body, open in substantially parallel to the board surface (component mounting surface 2a and solder surface 2b) of the main board 2, and communicated so that the caulking pin 5 can be inserted when the case is closed. Opening portions 311, 411, 412, and locking portions 31 b that are provided in the lid caulking portion 30, and the caulking pins 5 that are inserted into the opening portions 311, 411, 412 are locked so as not to be removable. When the lid case 3 and the body case 4 are closed and the caulking pin 5 is inserted from the opening 412 (see FIG. 5A), the caulking pin 5 is inserted through each opening 311, 411, 412. In addition, Locked to the part 31b, and a lid case 3 and the main body case 4 is sealed so as not to open (see Figure 5 (b)).
Hereinafter, the configuration of each unit will be described in detail.

As shown in FIG. 2, the lid caulking portion 30 and the main body caulking portion 40 are portions provided on the opposite side of the hinge portion 1a and projecting substantially parallel to the main board 2 from the outer edges of the cases 3 and 4. In the form, a total of four are provided, two on each side. Each of the caulking portions 30 and 40 is formed with a convex portion 31 and a concave portion 41 which are overlapped when the case is closed.
As shown in FIGS. 2 and 3A, the convex portion 31 is a portion that hangs down toward the main body case 4, and the convex portion 31 is substantially parallel to the substrate surface of the main substrate 2 and is a caulking pin. An opening 311 opened so that 5 can be inserted, and a locking portion 31b where the caulking pin 5 is locked are formed.

As shown in FIG. 2 and FIG. 3A, the recess 41 is a portion that opens toward the lid case 3, and is recessed so that the protrusion 31 is accommodated when the case is closed. A first opening 411 and a second opening 412 are formed, which are substantially parallel to the substrate surface of the main substrate 2 and are opened so that the caulking pins 5 can be inserted therethrough.
The first opening portion 411 and the second opening portion 412 are respectively positioned on the front end side and the rear end side of the caulking pin 5 inserted therethrough, and in the case closed state, the convex portion 31 (opening portion 311) is between them. It is supposed to be located.

The recess 41 is provided with a space 41a as shown in FIG. The space 41a is formed longer than the tip end portion (the head 51 described later) of the caulking pin 5 inserted into the first opening 411, and the lid caulking portion 30 separated from the lid case 3 is formed by the space 41a to the second. By sliding to the opening 412 side, the engagement between the first opening 411 and the caulking pin 5 is released (described later).
Then, as shown in FIG. 3B, when the case is closed, the first opening 411, the second opening 412 and the opening 311 arranged so as to be sandwiched therebetween communicate with each other, and the caulking pin 5 can be inserted.
At this time, the recess 41 is shielded from the outside by the lid caulking portion 30 serving as a lid.

The caulking pin 5 is an example of a pin material, and functions as a hook that seals the lid case 3 and the main body case 4 so that they cannot be opened by being inserted through the openings 311, 411, 412.
The caulking pin 5 is made of an industrial resin (for example, polycarbonate) that cannot be easily broken. As shown in FIG. 4, a head 51 that engages with the first opening 411, and a claw 52 that flexes elastically. The neck portion 53 is engaged with the engagement portion 31 b, and the body portion 54 is engaged with the opening 311 and the second opening 412.
The caulking pin 5 configured as described above is inserted through the openings 311, 411, and 412, thereby sealing the lid case 3 and the main body case 4 so that they cannot be opened as follows.

First, as shown to Fig.5 (a), the cover case 3 and the main body case 4 are closed, a case closed state is made, and each opening part 311,411,412 is connected.
Then, the head 51 is inserted into the second opening 412 and the caulking pin 5 is pushed in until the head 51 engages with the first opening 411 as shown in FIG. As a result, the caulking pin 5 is inserted through the openings 311, 411, 412.

  In this state, for example, when an external force is applied to lift the lid case 3 to open the substrate case 1, the upper surface of the first opening 411 and the head 51 come into contact with each other, and the bottom surface 31 a of the convex portion 31 and the trunk portion 54. The front end side abuts, and the upper surface of the second opening 412 and the rear end side of the body portion 54 abut, so that the caulking pin 5 acts to prevent the substrate case 1 from being opened. That is, the caulking pin 5 operates as a hook and seals the lid case 3 and the main body case 4.

Furthermore, since each opening 311, 411, 412 is arranged so that the first opening 411 and the second opening 412 sandwich the opening 311, the sealing force by the caulking pin 5 increases as follows. To do.
The caulking pin 5 is supported by the first opening 411 and the second opening 412 at both ends against an external force that attempts to open the substrate case 1, and the opening 311 (for example, the bottom surface) positioned therebetween. The force will be received from 31a). As a result, the external force is not applied only to one end as in the case of the one-end support, and an equal force is applied to the entire caulking pin 5, so that the resistance to the external force is remarkably improved. Thereby, the sealing force by the caulking pin 5 can be increased.

Further, the caulking pin 5 in the pushed-in state is locked so as not to be removable from each of the openings 311, 411, 412.
Specifically, the locking portion 31b is formed narrower than the respective opening portions 311, 411, 412, and the claw portion 52 passes through the locking portion 31b while being elastically deformed when pushed, When the portion 31b is exceeded, restoration is performed. As a result, the locking portion 31 b is sandwiched between the end portion of the claw portion 52 and the head portion 51. In other words, the neck portion 53 is locked to the locking portion 31b, and the caulking pin 5 cannot be removed.
In this state, since the concave portion 41 is shielded from the outside by the lid caulking portion 30, the claw portion 52 cannot be operated from the outside.
The substrate case 1 according to the present embodiment includes four caulking structures having the above-described configuration. As shown in FIG. 6, the caulking structure disposed on the inner side serves as a spare for resealing, and is provided at both ends. The caulking pin 5 is inserted into the caulking structure, and the lid case 3 and the main body case 4 are sealed so as not to be unsealed and attached to the housing 100b and shipped from the manufacturer.

Furthermore, as shown in FIGS. 6 to 8, the substrate case 1 includes a cover 6 that covers a joint portion between the lid case 3 and the lid caulking portion 30.
As shown in FIG. 7, the lid caulking portion 30 is formed integrally with the lid case 3 via joint portions 32 a and 32 b.
The joint portions 32a and 32b are formed in a beam shape that can be cut by a cutting tool such as a nipper. When the joint portions 32a and 32b are cut, the lid caulking portion 30 can be slid toward the second opening 412 side, The engagement between the opening 411 and the caulking pin 5 (head 51) is released, and the lid case 3 and the body case 4 can be opened (described later).
Therefore, a cover 6 that covers the joint portions 32a and 32b is provided so that the joint portions 32a and 32b cannot be easily cut. Hereinafter, the configuration of the cover 6 will be described with reference to FIGS.

The cover 6 is an example of a cover member, is formed of a transparent industrial resin material (for example, polycarbonate), and is configured to protect the joint portions 32a and 32b so as to be visible and uncut.
Specifically, as shown in FIG. 8, the cover 6 is formed in a substantially U shape, and includes an upper surface 6 a that covers the joint portions 32 a and 32 b and a side surface 6 b that covers the side surface of the lid caulking portion 30. It is comprised so that the two cover crimping parts 30 may be covered integrally (refer FIG. 6).
A screw hole 61 that communicates with the screw hole 33 formed in the lid caulking portion 30, a window portion 63, and a fragile portion 64 are formed on the upper surface 6 a.

The screw hole 61 communicates with the screw hole 33 by attaching the cover 6 to the lid caulking portion 30, and as shown in FIG. 7, the screw 6 is screwed in from the main body case 4 side so that the cover 6 is covered with the cover. Screwed onto the case 3.
Thus, by setting the screwing direction of the screw 7 from the main body case 4 side, as shown in FIG. 6, in the state where the lid case 3 and the main body case 4 are sealed, the operation of the screw 7 is caulked by the main body. The cover 6 is prevented by the portion 40 so that it cannot be detached from the lid case 3.

Two window portions 63 are provided independently at positions corresponding to the joint portions 32a and 32b of each lid caulking portion 30, and as shown in FIG. 8, the window portion 63 is partitioned by a thinly recessed portion 63a. It is an area. Thereby, the junction parts 32a and 32b of each lid caulking part 30 can be covered uncut.
A handle 63b is provided on the top surface side of each window 63, and by grasping and lifting the handle 63b, the thin part 63a can be broken and each window 63 can be opened independently (see FIG. 9 (a) and (b)). As a result, the joint portions 32a and 32b can be exposed to the outside so as to be cut, and a trace of breakage can be clearly left.
The fragile portion 64 is a portion that is formed in a thin lattice shape and is fitted to the notch portion 3a of the lid case 3 so as not to be detached. When the cover 6 is removed from the lid case 3, The lattice-like part is destroyed, and a part remains on the lid case 3 side. Thereby, the trace which removed the cover 6 can be left leaving the substrate case 1 open.
Further, the side surface 6b has an engagement hole 65 that engages with the claw portion 34 formed on the side surface of the lid caulking portion 30 and a protrusion that is inserted into the insertion port 42 (see FIG. 2) formed in the main body caulking portion 40. A portion 62 is formed.
Thus, by providing the cover 6, in order to expose the joint portions 32 a and 32 b, the window portion 63 is destroyed, so that the trace can be clearly left, and unauthorized modification to the main board 2 is suppressed. be able to.
In addition, by providing the window 63 independently at positions corresponding to the joint portions 32a and 32b of the two lid caulking portions 30, unless the caulking pin 5 is inserted and sealed in the two lid caulking portions 30, Either one of the windows 63 can be left for resealing.

Next, the operation of opening the substrate case 1 that is sealed so that it cannot be opened and the joint portion 32a is covered so that it cannot be cut will be described with reference to FIGS.

The window portion 63 is opened by breaking. As a result, as shown in FIG. 9B, the joint portions 32a and 32b are exposed to the outside, and the window portion 63 cannot be repaired, leaving a trace of opening. In this case, the window portion 63 (the left side in FIG. 9) corresponding to the lid caulking portion 30 on the side where the caulking pin 5 is not inserted does not require a breaking operation, and therefore the form until the opening after resealing is performed. Can be left as is.
Then, as shown in FIG. 9C, the joints 32a and 32b and the joints 66a, 66b, and 66c between the upper surface 6a and the side surface 6b are cut using a cutting tool such as a nipper.

When the joints 66a, 66b, and 66c are cut, the engagement between the claw portion 34 and the engagement hole 65 is released, and the cover 6 is released from the lid caulking portion 30.
Further, since the lid caulking portion 30 is separated from the lid case 3 by cutting the joint portions 32a and 32b, the lid case 3 is not only related to the lid caulking portion 30 but also to the main body case 4. Disappear.
Thereby, as shown in FIG.10 (b), the cover case 3 can be open | released.

Further, as shown in FIG. 10A, the lid caulking portion 30 and the main body caulking portion 40 can be separated as follows by sliding the divided lid caulking portion 30 in the direction b.
