Description

  The present invention relates to a technique for preventing an illegal act on a gaming machine.

  Conventionally, inside gaming machines such as so-called pachinko machines and slot machines, a CPU (Central Processing Unit), ROM (Read Only Memory) and RAM (RAM) that control the operation content (game production and various neglected operations) of the gaming machine. A main control board and a sub control board on which a control element such as Random Access Memory) is mounted are accommodated in a board case.

  The main control board is connected to various parts that operate in the gaming machine. For example, a main control board in a slot machine is connected to a sub control board to which a start lever that triggers the start of a game in the slot machine, a stop button for stopping rotation of each drum (reel), and the like are connected. The The sub control board and the main control board are connected by connecting a connector formed at one end of a harness bundled with a plurality of cables to the sub control board and connecting a connector formed at the other end to the main control board. Is done.

  In the slot machine, a signal is transmitted to the control board via a connector and a harness in response to an operation of a start lever or a stop button, and a random number generator on the control board generates a random number in response to the signal. The success or failure of the winning combination is determined by the generated random number.

  Conventionally, a fraudulent act has been performed in which a gaming machine is modified such as an unauthorized modification, and an illegal profit is obtained artificially. For example, the act of remodeling each element of the control board of the gaming machine, or removing the harness connector connected to the control board of the gaming machine from the gaming machine and connecting it to an unauthorized control circuit that is not a regular control circuit. The act has been carried out.

  For example, the following countermeasures have been taken against such fraud. As an example, the control board is sealed with a case to prevent modification of the control board itself. As another example, when a connector with a special structure is used as a connector for connecting a cable or the like to the control board, and the connector once connected is to be disconnected, a part of the connector must be destroyed. There is one that prevents the connection from being released (for example, Patent Document 1).

  As another example, after connecting a connector at one end of a harness connected to each part of the gaming machine and the control board, the connected part is sealed with a cover member (for example, Patent Document 2). ).

The engaging convex portions 71b and 71c and the engaging convex portions 72b and 72c provided in the are engaged. These engagement holes 335 to 338 are for strengthening the positioning when the connector protective cover 70 is attached and the fixing after the connector protective cover 70 is attached.

(Configuration of connector protective cover)
Next, the connector protective cover 70 will be described with reference to FIGS. FIG. 6A is a schematic plan view showing the cover member 311 and the connector protective cover 70 according to the first embodiment. FIG. 6B is a schematic side view seen from the arrow X direction of FIG. FIG. 6C is a cross-sectional view taken along the line BB in FIG. In FIG. 6, the cover member 311 and the cable 39 are not shown in their entirety, and a part of the illustration is omitted.

  As shown in FIG. 6A, the connector protective cover 70 is composed of a first cover piece 71 and a second cover piece 72 formed of polycarbonate resin. The first cover piece 71 and the second cover piece 72 are composed of the first cover piece 71 and the second cover piece 72. A connector protective cover 70 is configured by surrounding the connector lock members 331 and 332 at both ends of the female connector 33 and combining them so as to cover the periphery thereof (see FIGS. 5 and 11).

The first cover piece 71 and the second cover piece 72 are combined in the following manner. First, the first cut portion 71f formed at the end portion is inserted into the insertion hole 72h of the second cut portion 72f of the second cover piece 72 (see FIGS. 8 to 10). Next, the first cover piece 71 is rotated with the contact point of the inserted first cutout portion 71f and second cutout portion 72f as a fulcrum, and the engagement hook 71d of the first cover piece 71 is fixed to the second cover piece 72. It is accommodated in the recess 72d. At this time, the front end of the engaging hook 71d is hooked to the hooking portion 72e of the fixing recess 72d of the second cover piece 72, so that the first cover piece 71 does not come off from the second cover piece 72. Both are fixed and locked to each other (see FIGS. 11 and 12).
Hereinafter, the first cover piece 71 and the second cover piece 72 will be described.

<First cover piece>
The 1st cover piece 71 which comprises the connector protective cover 70 is provided with the flat plate-shaped member 71a as shown in FIG. An engagement hook 71d (corresponding to an example of the “ridge” in the present invention) as shown in FIG. 6A is provided on one end side of the planar portion of the plate-like member 71a. The engaging hook 71d protrudes from the plate-like member 71a so as to be substantially orthogonal, and the tip is bent and folded toward the plate-like member 71a, that is, formed into a bowl shape. The engaging hook 71d is accommodated in a fixing recess 72d (corresponding to an example of “a recess” and “a fixing recess” in the present invention) in the second cover piece 72 described later, and its tip is hooked on the hook 72e. Is done.

  Further, a step 71e as shown in FIGS. 5 and 6A and 6C is provided at the other end of the plate-like member 71a of the first cover piece 71 with respect to one end on the engagement hook 71d side. That is, the plate-like member 71a is formed in a flat plate shape, but the other end side is bent in the direction in which the engagement hook 71d protrudes and in the direction perpendicular to the extending direction of the plate-like member 71a. Furthermore, the other end side of the bent plate-like member 71a is again configured to be bent orthogonally toward the extending direction of the plate-like member 71a to form a step 71e (FIGS. 5 and 6A) ( C)). The length of the step 71e protruding in the protruding direction of the engagement hook 71d is at least the thickness of the second cutout 72f in the second cover piece 72 described later.

  As shown in FIGS. 5 and 6A, a step 71e portion on the other end side of the plate member 71a is provided with a first cutout portion 71f extending in the same direction as the plate member 71a. . The width of the base portion (the length in the direction orthogonal to the protruding direction) in the first cut portion 71f is narrower than the other portions. Further, the first cut portion 71f is formed in a substantially rectangular shape and is formed with a corner on the tip side in the protruding direction as shown in FIG. This is to allow the first cut portion 71f to be smoothly inserted into the insertion hole 72h.

  The step 71e of the plate-like member 71a of the first cover piece 71 has an engaging hook 71d of the first cover piece 71 as a second cover piece 72 with a contact point between a second cutout portion 72f and a first cutout portion 71f described later as a fulcrum. It is necessary to make it close to the fixed recess 72d. That is, if there is no step at the end of the plate-like member 71a on the first cutout portion 71f side, the engaging hook 71d becomes the fixed recess 72d even if the first cover piece 71 is rotated to the second cover piece 72 side. Before reaching, the first excision part 71f and the second excision part 72f abut against each other, and the first cover piece 71 can no longer approach the second cover piece 72.

  Therefore, a step 71e is provided in the plate-like member 71a in the present embodiment. As a result, even if the first cover piece 71 is rotated in the direction approaching the second cover piece 72 by the step 71e, the first cutout 71f is removed by the second cutout before the engagement hook 71d reaches the fixed recess 72d. It does not abut against the portion 72f (see FIG. 12C), and the connector protective cover 70 can be smoothly assembled.

  Further, as shown in FIGS. 5 and 6A, in the plate-like member 71a of the first cover piece 71, the engagement hook 71d is disposed between the engagement hook 71d on one end side and the step 71e on the other end side. A pair of engaging convex portions 71b and 71c that protrude in the same direction as the protruding direction are provided. The engaging projection 71b is engaged with the engaging hole 335 when the connector protective cover 70 is attached to the connector lock members 331 and 332. Similarly, the engaging convex part 71c is accommodated in the engaging hole 337 and engaged at the time of mounting. Therefore, the engagement protrusions 71b and 71c are formed in a size matching the inner shape of the engagement holes 335 and 337 so as to be engageable with the engagement holes 335 and 337.

  One engagement convex portion 71b is provided at a position separated by a predetermined distance from the position of the engagement hook 71d. The predetermined distance refers to the thickness of the wall (fourth surface described later) located on the center side of the fixed recess 72d among the four walls constituting the fixed recess 72d in the second cover piece 72 described later, and the connector lock. The distance is at least longer than the total length of the thickness from the end edge of the member 331 (the left end of the connector lock member 331 in FIG. 5) to the engagement hole 335.

  As shown in FIGS. 5 and 6A, in the plate-like member 71a of the first cover piece 71, the other engagement convex portion 71c is separated by a predetermined distance from the position of the engagement convex portion 71b. It is provided at a position on the other end side. This predetermined distance is substantially the same distance as the distance between the engagement hole 335 and the engagement hole 337 when the connector lock member 331 is fixed as shown in FIG. 5 (see FIG. 12C).

  The engaging projections 71b and 71c are used for positioning when the first cover piece 71 is attached to the connector lock members 331 and 332. Further, the engaging projections 71b and 71c ensure that the connector protective cover 70 is fixed to the connector lock members 331 and 332 after the connector protective cover 70 is attached to the connector lock members 331 and 332, respectively. Further, even if the connector protective cover 70 after attachment is moved in a direction away from the connector lock members 331 and 332, the engagement convex portions 71b and 71c can be locked and removed by the engagement holes 335 and 337. It becomes difficult.

  As shown in FIG. 5, the plate-like member 71 a in the first cover piece 71 is formed so as to bulge so that the portion slightly on the center side of the step 71 e is wider than the width of the other portions. This width is a width that is at least wider than the width of the insertion hole 72 h in the second cutout portion 72 f of the second cover piece 72. When the first excision portion 71f is inserted into the insertion hole 72h in the second cover piece 72, if the insertion hole 72h enters the portion of the plate-like member 71a, the engagement hook 71d is not aligned with the position of the fixing recess 72d. The position of the first cut portion 71f must be adjusted. Therefore, by forming the stepped portion 71e side of the plate-like member 71a to bulge, when the first cut portion 71f is inserted through the insertion hole 72h, the bulging portion is locked to the edge of the insertion hole 72h. Thus, the plate-like member 71a can be prevented from entering the insertion hole 72h.

  As shown in FIGS. 5 and 6B, the first cover piece 71 is an upper surface cover that protrudes from one side in the longitudinal direction of the plate-like member 71a in the same direction as the engagement hook 71d and the engagement protrusions 71b and 71c. 71g is provided. The upper surface cover 71g is connected to the upper surface of the male connector 38 (mainly connected to the female connector 33 together with the second cover piece 72 described later) when the connector protective cover 70 is attached to the connector lock members 331 and 332. The surface opposite to the control board 30 side) is covered.

  As shown in FIGS. 5 and 6A, the upper surface cover 71g has a size substantially the same as that of the hook at a position corresponding to a hook (not shown) in the upper surface cover 72g in the second cover piece 72 described later. Holes are provided. When the connector protective cover 70 is assembled, the hook engages with the hole, and the upper surface cover 71g and the upper surface cover 72g are locked and fixed, and assists in fixing the first cover piece 71 and the second cover piece 72. To do.

  Also, as shown in FIGS. 6A and 6B, from the side of the plate-like member 71a on the side of the engagement hook 71d that faces one side of the plate-like member 71a where the upper surface cover 71g is formed. A hook cover 71h is provided so as to be substantially parallel to the upper surface cover 71g and orthogonal to the plate-like member 71a. As shown in FIGS. 6A and 6B, the hook cover 71h is sized so as to cover the entire surface of the engagement hook 71d on the main control board 30 side (Y direction in FIG. 6B). Is done. When the connector protective cover 70 is attached to the connector lock members 331 and 332, the hook cover 71h, the fixing recess 72d of the second cover piece 72 described later, and the plate-like member 71a cover the entire engaging hook 71d. Become.

  Therefore, after the connector protective cover 70 is attached, the hooking state of the engagement hook 71d and the second cover piece 72 described later is illegally released using a wire or other jig without breaking the connector protective cover 70. Can be prevented.

  Further, as shown in FIG. 5, the plate-like member 71a of the first cover piece 71 is such that the side on which the hook cover 71h is provided is partly cut out between the engaging convex portions 71b and 71c. The width is narrow. When the connector protective cover 70 is attached to the connector lock members 331 and 332, the cable 39 bulges from the side of the male connector 38 shown in FIG.

  By cutting out the plate-like member 71a in this way. It is possible to prevent the cable 39 bulging from the male connector 38 and the plate-like member 71a from overlapping when the connector protective cover 70 is attached. Therefore, it is possible to prevent the distance between the inner wall of the connector protective cover 70 and the connector lock members 331 and 332 from being increased by the thickness of the cable 39 that bulges. As a result, it is possible to avoid a situation in which unauthorized modification or the like is performed by a jig or the like from the gap between the connector protection cover 70 and the connector lock members 331 and 332.

<Second cover piece>
Next, the 2nd cover piece 72 which comprises the other of the connector protective cover 70 is demonstrated with reference to FIG. 5 and FIG.

  As shown in FIG. 5, the second cover piece 72 includes a flat plate-like member 72 a (corresponding to an example of “first surface” in the present invention). Similar to the plate-like member 71 a of the first cover piece 71, the plate-like member 72 a also includes engagement convex portions 72 b and 72 c that engage with the engagement holes 336 and 338. Further, the length between the engaging projections 72b and 72c is also formed at the same interval as the interval between the engaging holes 336 and 338. Further, the plate-like member 72a has a narrow width between the engaging projections 72b and 72c so as not to overlap with the cable 39 bulging from the side surface of the male connector 38, like the plate-like member 71a in the first cover piece 71. It is cut out so that it becomes (FIG. 5).

  Further, as shown in FIG. 5, an upper surface cover 72g (corresponding to an example of the “second surface” in the present invention) is formed from one side in the longitudinal direction of the plate member 72a so as to be orthogonal to the plate member 72a. The The upper surface cover 72g is provided with a hook (not shown) that engages with the hole of the upper surface cover 71g of the first cover piece 71 on the surface on the main control board 30 side (lower side in FIG. 5).

  As shown in FIG. 5, a fixing recess 72 d for receiving the engagement hook 71 d of the first cover piece 71 is provided at the end of the plate-like member 72 a of the second cover piece 72 on the engagement protrusion 72 b side. Yes. As shown in FIGS. 5 and 6C, the fixed recess 72d is formed so as to be recessed from the end edge side of the upper surface cover 72g toward the plate-like member 72a. Further, as shown in FIG. 5, the fixed recess 72d is configured to be surrounded by four surfaces.

  Of these four surfaces, the first surface is a surface of the plate-like member 72a on the side where the engaging convex portions 72b and 72c are formed, and is a part of the end portion on the engaging convex portion 72b side. The second surface is a surface of the upper surface cover 72g on the main control board 30 side (Y direction side in FIG. 6B) and is a part of the end portion side on the engagement convex portion 72b side. The third surface and the fourth surface are orthogonal to the first and second surfaces and are disposed so as to face each other. That is, the third surface is continuously formed so as to be orthogonal to the edge of the plate-like member 72a and the edge of the upper surface cover 72g. The fourth surface is formed at a position separated from the third surface by a predetermined distance. The predetermined distance is a length that allows the engagement hook 71d of the first cover piece 71 to be accommodated.

  As shown in FIG. 5 and FIG. 6C, a latching portion 72e protruding toward the third surface side is formed at the edge of the fourth surface on the direction side where the engaging convex portion 72b protrudes. It is formed. The length by which the latching portion 72e protrudes in the direction of the third surface is such a length that the tip of the engagement hook 71d is latched. Further, a frame 72k that protrudes to the third surface as shown in FIG. 5 is provided from the opposite side (main control board 30 side) to the second surface of the latching portion 72e.

  The frame 72k is stretched between the fourth surface and the third surface as shown in FIGS. 5 and 6C. The frame 72k has a gap between the hook cover 71h of the connector protection cover 70 and the fixing recess 72d after the connector protection cover 70 is attached to the connector lock members 331 and 332, and from this portion, a wire or a jig is provided. Even if it is attempted to release the latching between the engagement hook 71d and the latching portion 72e by inserting a tool, it is possible for the frame 72k to inhibit the act and prevent an illegal act.

  Further, as shown in FIG. 5 and FIGS. 6B and 6C, in the second cover piece 72, at the end edge of the plate-like member 72a on the engaging convex portion 72c side (opposite side of the fixed concave portion 72d), A side cover 72m is provided so as to cover the side surface of the connector lock member 332 (corresponding to an example of “third side surface” or “fourth side surface” in the present invention) so as to be orthogonal to the upper surface cover 72g and the plate-like member 72a. The connector lock member 332 and the like cannot be accessed from the side cover 72m portion.

  As shown in FIGS. 5 and 6 (A) and 6 (C), the second cover piece 72 is continuous with the upper surface cover 72g, is orthogonal to the upper surface cover 72g and the side surface cover 72m, and is parallel to the plate member 72a. A projecting second excision 72f is provided. On the edges (a pair of sides) in the protruding direction of the second cutout 72f, as shown in FIGS. 5 and 6B, the plate-like member 72a side (opposite to the protruding direction of the engaging protrusion 72c). A pair of edge portions 72n projecting toward is provided. The space between the pair of edge portions 72n is formed so as to be wider than at least the width of the first cut portion 71f. After the connector protective cover 70 is assembled by the edge portion 72n (see FIGS. 12 and 13), there is no room for inserting a jig or the like between the first cutout portion 71f and the second cutout portion 72f. The connector protective cover 70 is illegally disassembled by shifting the 71f and the second cutout portion 72f with a jig or the like, and the male connector 38 and the like cannot be accessed.

  As shown in FIGS. 5 and 6C, an insertion hole 72h extending in the width direction of the second cutout 72f is formed at the base of the second cutout 72f. The length of the insertion hole 72h extending in the width direction is a length that allows at least the first cut portion 71f to be inserted. The first cut portion 71f is inserted through the insertion hole 72h.

(Connector protection cover installation process)
Next, the connector protective cover 70 will be described with reference to FIGS. 5 and 7 to 12. FIG. 7 is a schematic perspective view showing the female connector 33 according to the first embodiment, the first cover piece before attachment, and the second cover piece after attachment. FIG. 8 is a schematic perspective view showing the female connector 33 according to the first embodiment, the first cover piece just before attachment, and the second cover piece after attachment. FIG. 9 is a schematic perspective view showing the female connector 33 according to the first embodiment, the first cover piece 71 when the first cut portion 71f is inserted, and the second cover piece 72 after being attached.

  FIG. 10A is a schematic plan view showing the female connector 33 according to the first embodiment, the first cover piece 71 when the first cutout portion 71f is inserted, and the second cover piece 72 after being attached. FIG. 10B is a schematic side view seen from the arrow X direction of FIG. FIG. 11 is a schematic perspective view showing the female connector 33 according to the first embodiment and the connector protective cover 70 after being mounted and locked. FIG. 12A is a schematic plan view showing the female connector 33 according to the first embodiment and the second cover piece after being mounted and locked. FIG. 12B is a schematic side view seen from the arrow X direction of FIG. FIG. 12C is a cross-sectional view taken along line AA in FIG. In FIG. 6, the cover member 311 and the cable 39 are not shown in their entirety, and a part of the illustration is omitted.

  In the following description, a process of attaching the second cover piece 72 to the connector lock members 331 and 332 prior to the first cover piece 71 will be described as an example. However, in the connector protection cover 70 according to the present embodiment, the first cover It is also possible to attach the connector protective cover 70 by the process of attaching the piece 71 first.

  As shown in FIG. 5, before the connector protective cover 70 is attached, the first cover piece 71 and the second cover piece 72 are not attached to the connector lock members 331 and 332, and the connector lock members 331 and 332 are released. Thus, the male connector 38 can be released from the female connector 33.

  First, from the state shown in FIG. 5, the second cover piece 72 is attached as shown in FIG. At this time, the engaging convex portion 72 b of the second cover piece 72 is engaged with the engaging hole 336 of the connector lock member 331, and the engaging convex portion 72 c is engaged with the engaging hole 338 of the connector lock member 332.

  Next, from the state shown in FIG. 7, the first cover piece 71 is tilted so that the first cut portion 71f can be inserted into the insertion hole 72h of the second cover piece 72 as shown in FIG.

  Next, from the state shown in FIG. 8, the first cut portion 71 f of the first cover piece 71 is inserted into the insertion hole 72 h of the second cover piece 72 as shown in FIGS. 9 and 10 (A) and (B). At this time, the bulged portion on the step 71e side of the plate-like member 71a of the first cover piece 71 contacts the edge of the insertion hole 72h so that the first cover piece 71 is not inserted deeper than the step 71e portion. It is configured. Therefore, the first cover piece 71 is not inserted more than necessary into the insertion hole 72h of the second cover piece 72, and it is possible to avoid a complicated operation such as position adjustment when the engaging hook 71d is accommodated in the fixed recess 72d. It is.

  Next, from the state shown in FIG. 9, the first cover piece 71 is rotated with the contact portion between the first cut portion 71f of the first cover piece 71 and the insertion hole 72h of the second cover piece 72 as a fulcrum. And as shown to FIG. 12 (A)-(C), the engagement hook 71d in the 1st cover piece 71 is accommodated in the fixed recessed part 72d. When the work is completed as shown in FIG. 11, as shown in FIG. 12C, the engagement hook 71d of the first cover piece 71 is hooked to the hook 72e in the fixed recess 72d. Then, the first cover piece 71 and the second cover piece 72 are fixed, and the connector protective cover 70 and the connector lock members 331 and 332 are fixed.

  At this time, as shown in FIGS. 11 and 12B, the connector protective cover 70 covers the entire connector lock members 331 and 332 including the contact points between the locking claws 333 of the connector lock members 331 and 332 and the male connector 38. Further, as shown in FIG. 12C, the connector protective cover 70 covers the whole so that no gap is formed between the connector protective cover 70 and the connector lock members 331 and 332. Therefore, it is difficult to insert a jig or the like from the gap.

  When the connector protective cover 70 is locked as shown in FIGS. 11 and 12A to 12C, the locked state cannot be released unless the first cutout portion 71f and the second cutout portion 72f are cut off. Further, since the connector protective cover 70 covers not only the connector lock members 331 and 332 but also the contact points between the locking claws 333 of the connector lock members 331 and 332 and the male connector 38, the connector protective cover 70 is demolished. Unless it is, it is difficult to release the connection between the female connector 33 and the male connector 38.

(Removal process of connector protective cover)
Next, the removal process of the connector protective cover 70 will be described with reference to FIG. FIG. 13A is a schematic perspective view showing the main control board case 31 and the connector protective cover 70 before excision in the first embodiment. FIG. 13B is a schematic perspective view showing the main control board case 31 and the connector protective cover 70 after excision in the first embodiment. In FIG. 13, the cable 39 is not shown in its entirety, and is partially omitted.

  When both the first cutout portion 71f and the second cutout portion 72f are cut as shown in FIG. 13B from the state in which the connector protective cover 70 is attached as shown in FIG. 13A, the first cover piece 71 is cut. Since the fixed state of the second cover piece 72 is released, the first cover piece 71 can be detached from the second cover piece 72 and the locked state of the connector lock members 331 and 332 can be released as shown in FIG. It becomes.

  In this way, when performing maintenance or replacement of the connector or the main control board 30, it is only necessary to cut the first cutout portion 71f and the second cutout portion 72f of the connector protective cover 70 together with a jig or the like. Can do. Therefore, the operation can be easily performed.
