Description

  The present invention relates to a board case unit that houses a control board used for controlling a gaming machine.

A gaming machine such as a pachinko gaming machine is provided with a control board that controls the operation of an electronic component mounted on the gaming machine. For example, a control board called a main control board or a main control board is equipped with a ROM in which game machine control software is written, and has a role as a central control device for overall control of the game machine operation. doing. For this reason, the control board of the gaming machine is likely to be a target of action such as replacement with a counterfeit ROM or addition of an illegal circuit.

In order to prevent such fraud and provide a fair game, the control board is a board case composed of a bottom case formed of a transparent resin material and a top case that can be opened and closed in front of the case. Is housed inside. Further, when the top case is mounted in a closed state with respect to the bottom case, the engaging portion formed on the bottom case side and the engaging portion formed on the top case side are engaged and connected to the substrate case. Unauthorized opening prevention structure that locks the board case in the closed state and makes the board case unopenable unless the connecting part connecting the top case (or bottom case) and its engaging part is separated using a tool such as a nipper. (For example, refer to Patent Document 1).

Also, a wirelessly readable I / O that stores unique information of the gaming machine, identification information of the control board, etc.
It is also known to seal a substrate case by sticking a sealing seal having a C chip so as to straddle the boundary between the bottom case and the top case, and surrounding this with a seal cover member from the outside (for example, , See Patent Document 2). When using such a seal seal, if the seal seal is peeled off to open the substrate case, the seal seal is easily broken. Since it becomes impossible to read the stored information of the IC chip, it is possible to leave a trace when there is an unauthorized access to the substrate case.

Such a sealing sticker can contribute to countermeasures against unauthorized opening of the substrate case, but if it is illegally peeled off by a sophisticated technique (for example, peeled off using a release agent) and reused, the substrate case itself It becomes difficult to detect illegal activities such as exchanging Therefore, the seal cover member that surrounds the seal seal from the outside is provided with a breaking projection for breaking the seal seal so that the seal seal cannot be recovered when the seal cover member is removed when the substrate case is opened. A structure to be destroyed has been proposed (see, for example, Patent Document 3).

The second elastic piece 165 is provided to be inclined obliquely outward from the fixed end toward the free end. That is, in a side view of the pair of second elastic pieces 165 as viewed from the sliding direction (left-right direction), a substantially C shape (
Are formed so as to be spaced apart from each other toward the base wall 124 of the bottom-side sealing portion 123.

The connecting arm portion 166 has a rectangular cross section and extends in the vertical direction, and is connected to the pair of flat plate portions 163 at both ends thereof. The connecting arm portion 166, the pair of flat plate portions 163, and the cutter body 1
A rectangular empty portion 166 a surrounded by 61 is formed to be somewhat larger than the outer shape of the second pedestal portion 127. Therefore, the second pedestal portion 127 can be inserted through the empty portion 166a in the front-rear direction. In addition, the connecting arm portion 166 is a contact wall portion 135a of the top case 130.
(Details will be described later) with a slight gap in close proximity to each other in the front-rear direction, preventing the seal cutter member 160 from malfunctioning due to vibration generated in the substrate case 110 and unintentionally breaking the seal seal 150 To do.

6 are arranged so as to overlap each other.

Next, in order to facilitate understanding of the present embodiment, the operation of the main control board case unit 100 will be described. Here, FIG. 11 is a perspective view showing a state in which the seal cutter member 160 is attached to the bottom side sealing portion 123, and FIG. 12 is a diagram showing the seal cutter member 160 and the top side sealing portion 133.
FIG. 13 is a schematic view for explaining the operation of the seal cutter member 160 in the process of closing the substrate case 110, and FIG. 14 is a seal cutter member in the process of opening the substrate case 110. It is a schematic diagram for demonstrating the operation | movement of 160. FIG. In order to facilitate understanding of the description, in FIG. 12, only the top side seal part 133 and the seal cutter member 160 are extracted, and the illustration of the bottom side seal part 123 and the seal seal 150 is omitted.
In FIG. 13 and FIG. 14, only the top-side sealing portion 133, the sealing seal 150, and the seal cutter member 160 are extracted, and the bottom-side sealing portion 123 is not shown.

  First, an operation when the substrate case 110 is closed will be described.

First, in order to assemble the substrate case 110, although not shown in detail, the top case 13
The main control board 41 is screwed and fixed to the inner surface side of 0, and the main control board 4 is placed in the top case 130.
1 is attached. Subsequently, as shown in FIG. 11, the cutter main body 161 of the seal cutter member 160 is fitted and received in the cutter receiving portion 128 of the bottom seal portion 123, and the seal cutter member 160 is attached to the bottom seal portion 123. . At this time, the seal cutter member 1
In the process of attaching 60 to the bottom seal portion 123, the guide rib 1 of the first pedestal portion 126 is mounted.
Since 26b passes along the guide groove 161b of the seal cutter member 160, the mounting movement of the seal cutter member 160 is smoothly guided. In a state where the seal cutter member 160 is mounted on the bottom side sealing portion 123, the main breaking projection 161m is formed on the cutter receiving portion 128.
It is housed inside and does not protrude outward from the seal surface opening 128a. In addition, the sub-breaking protrusion 161s passes through the slit portion 126a of the first pedestal portion 126 and passes through the hole portion 12 of the base wall 124.
4 a and is not protruded outward from the end face of the base wall 124.

Subsequently, the seal seal 150 is bent in an L shape, and the seal seal 150 is stuck across the first seal sticking part X1 and the second seal sticking part X2. Here, in the seal seal 150, the first half 151 attached with the character information of “open prohibition” is attached to the first seal attachment X1, and the second half attached with the QR code 154. The part 152 is stuck on the second seal sticking part X2. At this time, since none of the breaking protrusions 161m and 161s protrudes outward from the seal sticking portion X, the seal sticking is performed without bringing the sealing seal 150 into contact with the breaking protrusions 161m and 161s (without causing any damage). It can be attached to part X.

When the seal seal 150 is attached to the seal attachment portion X, the seal surface opening 128a (cutter receiving portion 128) is covered by the seal seal 150, and the main breaking protrusion 161m is formed at the closest position on the back side of the seal seal 150. Will be placed. At this time, since the QR code 154 portion attached to the seal seal 150 is disposed on the seal surface opening 128a, the QR code 154 portion and the main fracture protrusion 161m face each other in the cutter advancement direction. Further, the two slit portions 126a of the first pedestal portion 126 are covered from the side by the seal seal 150,
The sub-breaking protrusion 161s is disposed in the vicinity of the end side of the seal seal 150 (first half portion 151).

Subsequently, the top side sealing portion 133 (top case 130) is overlapped with the bottom side sealing portion 123 (bottom case 120) at a position slightly shifted to the right. As shown in FIG. 13A, in the process of overlapping the top case 130 with the bottom case 120,
The guide protrusion 136 of the top seal part 133 is the second elastic piece 165 of the seal cutter member 160.
To touch. At this time, by receiving a pressing force from the guide projection 136, the second elastic piece 165 is displaced from the free state expanded outward by its own tilting action to the state pressed inward (
Elastically deformed). Therefore, the guide protrusion 136 of the top-side sealing portion 133 is provided with the second elastic piece 1
It slides on the second elastic piece 165 while pushing 65 inward. Then, when the guide protrusion 136 gets over the second elastic piece 165 and the mutual contact is released, the second elastic piece 165 returns to its original free state by its own restoring elasticity. As will be described in detail later, even if it is attempted to remove the top side sealing portion 133 from the bottom side sealing portion 123 from this state, the second elastic piece 165 has already been obtained.
Is in a free state (a state in which it is expanded outward), the guide protrusion 136 has the second elastic piece 16.
5, the top side sealing part 133 cannot be removed unless the top side sealing part 133 is lifted together with the seal cutter member 160 with respect to the bottom side sealing part 123.

Subsequently, the top side sealing portion 133 (top case 130) is slid in the closing direction with respect to the bottom side sealing portion 123 (bottom case 120), and the top case 130 is slid and attached to the bottom case 120. Thereby, the bottom side slide engagement part 51c and the top side slide engagement part 61d are engaged, and the bottom case 120 and the top case 130 are integrated in a closed state in which the openings are opposed to each other.

In the slide mounting process, the top seal portion 133 moves relative to the seal cutter member 160 mounted on the bottom seal portion 123 in the closing direction. FIG.
As shown in (B), in this relative movement, the first inclined portion 136 of the top-side sealing portion 133 is used.
When b1 comes into contact with the first elastic piece 164 (engagement shaft portion 164b) of the seal cutter member 160, the first elastic piece 164 is elastically deformed inward from the free posture under the action of the inclined surface of the first inclined portion 136b1. However, the first inclined portion 136b1 is slidably contacted along the closing direction. And first
When the engaging shaft portion 164b of the elastic piece 164 gets over the first inclined portion 136b1, the first elastic piece 164 returns to its original free state by its own restoring elasticity, and the engaging shaft portion of the first elastic piece 164 164b and the hook-shaped protrusion 136c of the guide protrusion 136 are engaged with each other. On the other hand, in the slide mounting process, the second elastic piece 165 is not in contact with the guide protrusion 136 and maintains a free state protruding outward.

In the state where the top case 130 is assembled to the bottom case 120 in this way, as shown in FIGS. 12 and 13C, the hook-shaped protrusion 136c bent in a semicircular arc has the cylindrical engagement shaft portion 164b on the inside. Since it is received and concealed from the right side, unauthorized access such as releasing the engagement between the engagement shaft portion 164b and the hook-shaped protrusion 136c from the side of the substrate case 110 can be made difficult. Further, since the L-shaped protective wall portion 135b is provided so as to overlap with the hook-shaped protrusion 136c when viewed from the sliding direction, the engagement shaft portion 164b and the hook-shaped protrusion are formed from the side of the substrate case 110. Unauthorized access that releases the engagement with 136c can be more strictly prevented.

Further, since the vertical wall 124b of the bottom side sealing portion 123 and the side wall 135 of the top side sealing portion 133 are arranged to overlap with each other at a position aligned with the first elastic piece 164 of the seal cutter member 160, these double By shielding with a barrier, unauthorized access from the side of the substrate case 110 can be prevented.

Further, since the connecting arm portion 166 of the seal cutter member 160 and the abutting wall portion 135a of the top case 130 face each other with a slight gap, the seal cutter member 160 malfunctions due to vibration generated in the substrate case 110. The situation where the seal seal 150 is unintentionally broken is prevented.

On the other hand, when the top case 130 is slid and attached to the bottom case 120, the bottom side lock portion 122 and the top side lock portion 13 are used in the structure for preventing unauthorized opening of the substrate case 110.
2 is overlapped in the front-rear direction, and in this state, the lock member 140 is inserted so as to straddle the top-side lock hole 132a and the bottom-side lock hole 122a. The lock part 122 is connected, and the top case 130 is attached to the bottom case 120 so as not to be opened (unless the connecting part 132b is cut off).

When the substrate case 110 is in a closed state, the lock member 140 may be moved to the top side lock portion 1 even if the top case 130 is slid in the opening direction with respect to the bottom case 120.
32 and the bottom-side lock portion 122, the slide movement is restricted.

Thus, when the substrate case 110 is held in the closed state, it is difficult to access the main control substrate 41 accommodated in the substrate case 110 from the outside. Here, a QR code 154 as a two-dimensional barcode is recorded on the surface of the seal seal 150, and the substrate case 1
10, various information stored in the QR code 154 can be read from the outside by a QR code reader without opening the substrate case 110. Conventionally, a technique has been proposed in which the seal cutter member 160 is mounted so as to cover the entire seal seal 150. In this case, the state of the seal seal 150 is confirmed from the outside of the substrate case 110. The top case 130 and the seal cutter member 1
However, in this embodiment, the seal cutter member 160 is housed inside the seal seal 150, so that the top case 130 is stored. Since the state of the seal seal 150 can be confirmed only through this, the visibility of the seal seal 150 in the substrate case 110 can be improved as compared with the conventional case, and the efficiency and accuracy of the confirmation work can be improved.

  Next, the operation when opening the substrate case 110 will be described.

First, in order to open the substrate case 110, the connecting portion 132b that connects the top side lock portion 132 and the top case main body 131 in the unauthorized opening prevention structure is cut using a tool such as a nipper, and the lock member 140 is interposed. Then, the top side lock part 132 engaged with the bottom side lock part 122 is separated from the top case body 131. As a result, the connection between the bottom case 120 and the top case 130 is broken, and the substrate case 110 can be opened.

As shown in FIG. 14A, in a state before the substrate case 110 is opened, the fracture protrusions 161m and 161s of the seal cutter member 160 are not in contact with the seal seal 150 and are close to each other with a predetermined gap. Has been placed. That is, the main breaking protrusion 161m is received in the cutter receiving portion 128 in a state covered from behind by the seal seal 150,
The tip of the main breaking protrusion 161m and the second half 152 of the seal seal 150 are close to each other in the front-rear direction (cutter advance direction). The sub-breaking protrusion 161s is received in the hole 124b, and the sub-breaking protrusion 161s and the first half 151 of the seal seal 150 are arranged in the front-rear direction (
It is close to the cutter advance direction.

When the top case 130 is slid in the opening direction, as shown in FIG.
The hook-shaped protrusion 136c of the top seal part 133 and the engagement shaft part 16 of the seal cutter member 160
After the engagement with 4b is released, the inclined protrusion 136b of the top-side sealing portion 133 and the engagement shaft portion 164b of the seal cutter member 160 contact in the sliding direction. At this time, the engagement shaft portion 1
64b abuts on the inclined protrusion 136b (second inclined portion 136b2) and the bottom side sealing portion 123
The seal cutter member 160 moves in the direction approaching the ceiling wall 134 (cutter advancement direction) along the guide protrusion 136 by receiving a pressing force in a direction away from the ceiling wall 134. That means
By the action of the inclined surface of the second inclined portion 136b2, the linear motion in the sliding direction (left and right direction) by the top side sealing portion 133 is converted into the linear motion in the sliding orthogonal direction (cutter advance direction) by the seal cutter member 160. The Thereby, the seal cutter member 160 protrudes outward from the cutter receiving portion 128, and the first seal attaching portion X1 and the second seal attaching portion are formed on the cutter receiving portion 128 (seal surface opening 128a). Since the seal seal 150 is stuck across X2, the main fracture protrusion 161m of the seal cutter member 160 contacts the seal seal 150 and breaks it. Further, since the seal seal 150 is attached to the first seal attaching part X1 of the first pedestal part 126 so as to close the two slit parts 126a, when the seal cutter member 160 is moved in the cutter advancement direction, The sub-breaking protrusion 161s of the seal cutter member 160 comes into contact with the sealing seal 150 while passing through the slit portion 126a and breaks it. If the seal seal 150 is broken in this way, the trace when the seal seal 150 is opened remains clearly, and an illegal act can be detected at an early stage. In addition, by cutting the QR code 154 portion in the seal seal 150,
Since various information stored in the QR code 154 becomes substantially unreadable, it is possible to leave a trace of unauthorized access and to destroy the seal seal 150 to the extent that it cannot be reused.

Further, when the seal cutter member 160 moves in the cutter advancement direction, the connecting arm portion 166 of the seal cutter member 160 abuts against the abutting wall portion 135a of the top side seal portion 133 and receives a pressing load. Then, the separation part (fragile part) 13 is connected via the connecting arm part 166.
When the pressing load acting on 3a exceeds its own mechanical strength (breaking strength), the separation portion (fragile portion) 133a where the stress concentration has occurred is broken, and the connecting arm portion 1 is disconnected from the seal cutter member 166.
66 is cut off. Therefore, in this way, the connecting arm portion 16 from the seal cutter member 160.
If 6 is separated, the trace when the substrate case 110 is opened remains, and the seal cutter member 160 can be made unusable in an intact state. for that reason,
The same type of board case (110) is taken out from a plurality of used machines, etc., and the case components are extracted from these in an intact state, and are combined appropriately, so that one new board case (110) is obtained. Even if it is used for a fraudulent act called so-called two-to-one (Nikoichi), which duplicates and replaces this with a genuine product, the seal cutter member 160 and the seal seal 150 clearly have fracture marks, The cheating can be easily detected.

In order to illegally open the substrate case 110, an unauthorized tool is inserted into the substrate case 110 from the outside, and the first elastic piece 164 of the seal cutter member 160 is pressed inward using the unauthorized tool. The engagement shaft portion 164b and the top side sealing portion 1 of the first elastic piece 164
Even if the engagement with the hook-shaped protrusion 136c of 33 is released, if the top case 130 is slid with respect to the bottom case 120 in this state and then removed in the front-rear direction, the seal cutter member 160 Since the second elastic piece 165 is in an expanded state in a free state, the seal cutter member 160 advances into the cutter when the guide protrusion 136 of the top case 130 abuts against the free end side of the second elastic piece 165. Pressed in the direction. As a result, the seal cutter member 160 protrudes outward from the cutter receiving portion 128, so that the fracture protrusions 161m and 161s of the seal cutter member 160 come into contact with the seal seal 150 and break. Therefore, in this embodiment, unless the elastic pieces in total (two first elastic pieces 164 and two second elastic pieces 165) are operated simultaneously and individually, the sealing seal 150 is not broken, The substrate case 110 cannot be substantially opened.

As described above, according to the seal sealing structure according to the present embodiment, the substrate case 110 is opened because the substrate case 110 cannot be opened without destroying the seal seal 150 and the seal cutter member 160. In some cases, the trace can be clearly left to detect the illegal act at an early stage, and the unauthorized opening of the substrate case 110 can be suppressed to make it difficult to receive an unauthorized modification to the main control board 41. Is possible. In addition, since the component parts of the substrate case 110 cannot be reused in a state where there is no destruction mark, it is possible to prevent a so-called fraudulent act called “Nikoichi”. Therefore, according to the present embodiment, it is possible to contribute to prevention and early detection of fraud.

Further, in the present embodiment, when the substrate case 110 is assembled, the structure does not require secondary processing such as welding or adhesion, so that the assembly workability can be improved and the manufacturing cost can be reduced.

In the present embodiment, when the substrate case 110 is in the closed state, the cutter body 161
Is covered with the seal seal 150 and concealed inside the pedestal 125, making it difficult for an unauthorized person to recognize the location of the seal cutter member 160 and making it difficult to access the seal cutter member 160. Can do. Further, the seal cutter member 160
Is stored inside the seal sticker 150, so that the state of the seal sticker 150 can be confirmed only through the top case 130, so that the seal sticker 1 in the substrate case 110 is compared with the conventional case.
The visibility of 50 can be improved and the efficiency and accuracy of confirmation work can be improved.

Further, in the present embodiment, the seal cutter member 160 is linked to the sliding direction between the first seal attaching part X1 and the second seal attaching part X2 in conjunction with the sliding operation of the top case 130 (
Since the opening operation is performed in a direction orthogonal to the opening direction, the sealing seal 150 can be reliably broken regardless of the sticking posture of the sealing seal 150. Regarding this phenomenon, FIG.
With reference to 5 additionally, it demonstrates, comparing a prior art and this embodiment. FIGS. 15A and 15B are schematic views showing a state of breakage of the conventional seal seal 150, and FIG. 15C is a schematic view showing a state of breakage of the seal seal 150 in the present embodiment.

First, conventionally, as shown in FIG. 15A, the seal seal 150 is bent in an L shape, and the first half 151 is adhered to the left surface of the pedestal 125 'and the second half 152 is When the seal cutter member 160 ′ is moved in the sliding direction (left-right direction) along the slit portion 125b ′ of the pedestal portion 125 ′ when it is attached to the upper surface of the pedestal portion 125 ′, the breaking protrusion 161 is obtained.
Since the initial contact portion of ′ with respect to the seal seal 150 is the end of the seal seal 150 (the right end in FIG. 15), the end of the seal seal 150 is brought into contact when the fracture protrusion 161 ′ contacts the end of the seal seal 160. May peel off and roll up, and the seal seal 150 may not be properly broken.

Therefore, conventionally, as shown in FIG. 15 (B), the seal seal 150 is bent in an L shape, and the first half 151 is adhered to the right surface of the pedestal 125 ′ and the second half 152. Is adhered to the upper surface of the pedestal portion 151 ′, so that the breaking projection 16 can be obtained even when the seal cutter member 160 ′ is moved in the sliding direction along the slit portion 125b ′ of the pedestal portion 125 ′.
Since 1 'contacts at a substantially central portion of the seal seal 150, the seal seal 150 is prevented from being squeezed so that the seal seal 150 can be appropriately broken. However, the seal 15
When the first half 151 of 0 is stuck on the right side of the pedestal 125 ′, the character information “no opening” printed on the first half 151 is hidden inside the pedestal 125 ′. There arises a problem that it becomes difficult to read the character from the outside of the substrate case 110.

On the other hand, in the present embodiment, as shown in FIG. 16C, the seal seal 150 is bent in an L shape so that the first half body 151 is placed on the right side of the pedestal 125 (the first seal sticking portion). X1) and the second half 152 is pasted on the upper surface (second seal pasting portion X2) of the pedestal 125, the seal cutter member 160 is connected to the first seal pasting portion X1 and the second seal pasting portion X1. By moving in the direction perpendicular to the sliding direction (cutter advance direction) between the seal sticking part X2 and the main breaking protrusion 161m contacts at the substantially central part of the seal seal 150, the seal seal 150 is swollen. Since the seal seal 150 can be appropriately broken while preventing the character information “unopened” printed on the first half body 151 from being exposed to the outside,
The character information can be easily read even from the outside of the substrate case 110.

Thus, in this embodiment, the advancing direction of the seal cutter member 160 is different from the sliding direction of the substrate case 110, and the seal cutter member 160 is used as the seal seal 1.
Since it bites in the direction perpendicular to the main surface of 50 (at least in the direction intersecting), it does not depend on the method of sticking the seal seal 150, the shape of the seal cutter member 160, etc. When opened, the seal seal 150 can be accurately broken to render it non-reusable. Therefore, compared with the conventionally proposed technique for moving the seal cutter member in the same direction as the sliding direction of the substrate case, it is possible to dramatically improve the security against fraud.

<Seal Sealing Structure: Second Embodiment>
Next, the main control board case unit according to the second embodiment will be described with reference to FIGS. The main control board case unit of the second embodiment has basically the same configuration as the main control board case unit of the first embodiment described above. Hereinafter, the same components are the same. The description is abbreviate | omitted and description is abbreviate | omitted and it mainly demonstrates a different part.

Converted. As a result, the seal cutter member 160 protrudes outward from the cutter receiving portion 128 ′.
Since the sealing sticker 150 is stuck on 8 'across the first sticking part X1 and the second sticking part X2, the main breaking protrusion 161m of the seal cutter member 160 contacts the sealing stick 150. This will break. If the seal seal 150 is broken in this way, the trace when the seal seal 150 is opened remains clearly, and an illegal act can be detected at an early stage. Further, by tearing off the QR code 154 portion of the seal seal 150, various information stored in the QR code 154 becomes substantially unreadable, so that traces of unauthorized access can remain, and the seal is sealed. The seal 150 can be broken to an extent that it cannot be reused.

As described above, according to the sealing structure according to the second embodiment, without destroying the seal seal 150,
Since the substrate case 110 cannot be opened, when the substrate case 110 is opened, the trace can be clearly left and the fraud can be detected at an early stage. It is possible to prevent unauthorized opening to the main control board 41 by preventing unauthorized opening. Therefore, according to the present embodiment, it is possible to contribute to prevention and early detection of fraud.
