Description

  The present invention relates to a board box for accommodating various control boards in a gaming machine, and more particularly, to a board box for a gaming machine having a structure in which a main body and a lid are integrally coupled to each other by a sealing portion. It is.

  As one of the board boxes of the gaming machine, as shown in Patent Document 1, a plate-like frame body and a lock plate are respectively formed on the end surface portions of the side plate portions facing the box body and the lid, With the lid body slightly shifted along the sliding direction, after overlapping the openings so that they are on the inside, the box body and the lid body are slid relative to each other so that one lock plate is moved to the other. In some cases, a sealing portion provided separately is inserted into the plate-shaped frame body and integrally joined with a one-way screw.

However, the substrate box with the above structure is illegal because the main body and the lid can be separated only by sliding each other when the box arm or the opening arm portion that connects the lid and the sealing portion is cut by fraud. As the prevention structure, the structure depends only on the sealing portion, and is not reliable from the viewpoint of preventing fraud.
JP 2000-176132 A

  The problem of the present invention is that, in a substrate box having a sealing portion, even if the box main body and the lid body can be separated by cutting the opening arm portion, the separation structure cannot be easily understood. It is to prevent unauthorized opening.

  The first solving means for solving the above problem is that each side plate portion is arranged inside the box body from which only one side plate portion is missing and the remaining three side plate portions of the box body. The lid body is fitted into the box body by sliding insertion from the side plate missing portion of the box body, and the box body and the lid body are inserted and fitted with the other fitting projection into one fitting hole. A board box of a gaming machine having a structure assembled together, and an end face of at least one side plate portion along the slide insertion direction of the lid body is formed with a locking step portion that lowers the anti-slide insertion side A minute locking projection that can be locked to the locking stepped portion protrudes from a portion corresponding to the locking stepped portion of the lid inside the bottom plate portion of the box main body. Relative to At the end of the slide, both engaging step portion of the lid rides over the small locking projection of the box body is characterized by a structure that locks.

  According to the first solving means, in the state in which the locking stepped portion of the lid gets over the minute locking projection of the box body and the both are locked, the box body is separated from the box body. On the other hand, if an attempt is made to slide the lid in the opposite direction to that during assembly, a pressing force always acts on the top plate portion of the lid. The pressing force acts so that the minute locking projection of the box body and the locking step portion of the lid body are more strongly locked, so that the locking step portion of the lid body gets over the minute locking projection of the box body. It becomes even more difficult. That is, the pressing force acts so that the locking between the minute locking protrusion of the box main body and the locking stepped portion of the lid body is not released, so that it becomes extremely difficult to separate the box main body and the lid body.

  In addition, since the above-described locking structure is inconspicuous, even if the substrate box is made of a transparent member, it is difficult to understand how to open the lid at first glance. In this way, it is extremely difficult to open the lid with respect to the box body, and since the method of opening the lid cannot be understood at first glance, illegal acts can be effectively prevented.

  Further, the second solving means is characterized in that, in the first solving means, slits along the slide insertion direction are respectively formed on both sides of the minute locking projections in the bottom plate portion of the box body.

  According to the second solving means, when the lid is slid into the box body, the portion on the slide insertion side with respect to the locking stepped portion of the end surface of the side plate of the lid is a minute part of the bottom plate of the box body. When the portion where the locking projection is formed is reached, the front and rear portions of the bottom plate portion of the box body that form the minute locking projection are slightly elastically deformed outward. It becomes easy to get over the locking projection, and after the locking stepped portion and the minute locking projection are locked, the front and rear portions where the minute locking projection is formed are restored to the original shape by elastic deformation, Ensure locking.

  Further, in the first or second solving means, the third solving means is a concave shape in which the outer side is concave in the side plate part of the lid that is in close contact with the side plate part facing the side plate missing part of the box body. A tool insertion hole opened on the top plate portion side of the lid is formed between the concave portion and the side plate portion of the outer box body.

  According to the third solving means, with the tip of the rod-shaped tool inserted into the tool insertion hole being applied to the outside of the side plate portion of the lid, the end portion on the end surface side of the side plate portion of the outer box body is a fulcrum. When the tool is squeezed, a force in a direction to lift the lid from the box body acts on the lid. For this reason, the locking between the minute locking protrusions of the box body and the locking stepped portion of the lid is easily released, and the lid can be easily removed.

  According to the present invention, in order to separate the box main body and the lid body from each other in the state where the locking stepped portion of the lid gets over the minute locking protrusion of the box main body and both are locked, If you try to slide the lid in the opposite direction to the assembly, a pressing force always acts on the top plate of the lid, and the small locking projection on the box body and the locking step on the lid Since it acts so as to be more strongly locked, it becomes more difficult for the locking stepped portion of the lid to get over the minute locking protrusion of the box body. Further, in the above-described locking structure, since the minute locking protrusion is not conspicuous, it is difficult to understand how to open the lid at first glance. As described above, since it is extremely difficult to open the lid with respect to the box body and the method of opening the lid cannot be understood at a glance, the effect that can contribute to prevention of fraud is great.

Hereinafter, the present invention will be described in more detail with reference to the best mode for carrying out the present invention. FIG. 1 is a front view of a gaming board 1 of a gaming machine equipped with a substrate box B containing a liquid crystal display control substrate V of a liquid crystal display device A on the back, FIG. 2 is also a rear view, and FIG. FIG. 3 is a rear perspective view of the game board 1 in a state where a substrate box B containing a liquid crystal display control substrate V is separated. 1 to 4, a liquid crystal display control board holder H ₁ having a U-shaped side surface shape is attached to the back side of the game board 1. The upper side of the liquid crystal display control board holder H ₁ is directly attached to the back side of the game board 1, and the lower side is also attached to the main control board holder H ₂ directly attached to the game board 1. . As a result, when the liquid crystal display control board holder H ₁ is attached to the back side of the game board 1 as described above, a large side opening 11 is formed on the side face of the liquid crystal display control board holder H ₁ . _On the box mounting surface 12 of the liquid crystal display control substrate holder H1, a rectangular insertion opening 13 is formed through which the liquid crystal display device A mounted on the front surface of the box body 20 of the substrate box B containing the liquid crystal display control substrate V can be inserted. Has been.

Next, the substrate box B that houses the liquid crystal display control substrate V will be described. 4 is an exploded perspective view of the box body 20 and the lid body 40 constituting the substrate box B, FIG. 5 is a perspective view of the lid body 40 viewed from the inside, and FIG. FIG. 7 is a perspective view in the middle of assembling the cover body 40 by sliding the cover body, FIG. 7 is a view of the substrate box B viewed from the back side (the cover body 40 side), and FIG. It is an enlarged front view of the portion of the minute locking projection 29 of the box body 20, wherein (b) and (c) are cross sections taken along lines X ₁ -X ₁ and X ₂ -X ₂ respectively. 9 (a) and 9 (b) are the YY lines in FIG. 7 during the assembly of the box body 20 and the lid body 40 (in the middle of the slide insertion) and after the assembly (after the slide insertion is completed). It is sectional drawing. The substrate box B has a box body 20 having a mounting portion 21 on the outer surface for mounting the liquid crystal display device A, and is mounted on the back side of the box body 20 by sliding, and an opening on the back side (back side) of the box body 20. And a lid 40 that closes.

  As shown in FIG. 4, the box body 20 has a shape in which a side plate portion on one side of a rectangular box is omitted and an opening 22 is formed, and includes a bottom plate portion 23 and a slide insertion direction P ( 6) and a pair of first side plate portions 24 along a direction orthogonal to the slide insertion direction P. In the bottom plate portion 23, a large number of heat radiation holes 23b having an inner diameter of 2 mm or less are intensively formed at two portions where the overall shape is rectangular.

  On the other hand, as shown in FIGS. 4 and 5, the lid 40 accommodates the liquid crystal display control board V with an electronic component (not shown) mounted on the surface facing the top plate 41 described later. Thus, it is slid and inserted in the slide insertion direction P from the opening 22 of the box body 20, and is accommodated inside the box body 20, and includes a top plate portion 41 and a pair of firsts along the slide insertion direction P. A side plate portion 42 and a pair of second side plate portions 43 along a direction orthogonal to the slide insertion direction P are provided. The second side plate portion 43 on the side opposite to the slide insertion side of the lid body 40 is formed in a step shape along the slide insertion direction P, and includes an outer second side plate portion 43a and an inner second side plate portion 43b. A substrate mounting plate portion 44 is formed between the two side plate portions 43a and 43b, and a recess 50 is formed between each of the second side plate portions 43a and 43b, the substrate mounting plate portion 44, and the pair of left and right first side plate portions 42. Has been. The liquid crystal display control substrate V is attached to the inner side surface of the substrate mounting plate portion 44 and a pair of left and right substrate insertion grooves 45 formed on the inner side surface of the second side plate portion 43. The substrate insertion groove 45 forms a predetermined gap between the protrusion 46 protruding from a portion near the end surface of the second side plate 43 on the inner surface of the second side plate 43 and the protrusion 46. Thus, the second side plate portion 43 is formed between the forming end of the inner bulging portion 47 having a shape bulging inward. By forming the inner bulging portion 47 in the second side plate portion 43, a pair of left and right concave portions 48 reaching the protrusion 46 is formed on the outer surface of the second side plate portion 43 of the lid body 40. The top plate portion 41 has a large number of heat radiation holes 41b having an inner diameter of 2 mm or less at two separated locations.

  In a state where the lid body 40 is assembled to the box body 20 by sliding insertion, a pair of first side plates constituting the lid body 40 are respectively provided inside the pair of first side plate portions 24 and second side plate portions 25 constituting the box body 20. The first side plate portion 42 and the second side plate portion 43 are arranged in a stacked state (see FIG. 6). Further, the top plate portion 41 of the lid body 40 has a width direction (a direction orthogonal to the slide insertion direction) by the thickness of the first side plate portion 24 of the box body 20 rather than the outer side surfaces of the pair of first side plate portions 42. In the state where the lid body 40 is assembled to the box body 20 by sliding, the end portions in the width direction of the top plate portion 41 of the lid body 40 are in close contact with the end surfaces 24a of the pair of side plate portions 24 of the box body 20. At the same time, the front end surface 41 a of the top plate portion 41 abuts against the inner surface of the upper end portion of the second side plate portion 25 of the box body 20, and the end surface 25 a of the second side plate portion 25 of the box body 20 and the lid body 40. Since the outer surface of the top plate portion 41 is the same surface, the first side plate portion 24 of the box body 20 is lower than the second side plate portion 25 by the thickness of the top plate portion 41 of the lid 40. Is formed.

Further, as shown in FIGS. 4 and 8, the end of the first side plate portion 42 of the lid 40 on the slide insertion side has an original height by a predetermined length (L ₁ ) (see FIG. 4). Since most of the remaining portion is formed low by the height (L ₂ ), a locking step portion 49 is formed at a portion where the height of the first side plate portion 42 of the lid 40 is different. Corresponding to the above-described configuration of the first side plate portion 42 of the lid body 40, a portion having a predetermined width along the slide insertion direction P of the end portion on the opening 22 side of the bottom plate portion 23 of the box body 20 is almost the remaining portion. Is formed higher than the portion occupying the height (L ₂ ) to form a step [see FIG. 9 (A)]. Then, in a state where the lid body 40 is assembled to the box body 20 by slide insertion, the first end surface 42a on the slide insertion side of the first side plate portion 42 of the lid body 40 abuts on the bottom plate portion 23 of the box body 20. The portion of the remaining end surface 42b of the first side plate portion 42 of the lid 40 on the side opposite to the slide insertion comes into contact with the step bottom plate portion 23a of the box body 20 (see FIG. 9B).

  Next, in a state where the lid body 40 is assembled by sliding insertion with respect to the box body 20, the box body 20 and the lid body 40 are connected to each other at a plurality of locations by a mutual fitting structure. They are integrated so as not to be separated, and these fitting structures will be described together. First, a pair of left and right first fittings that are flush with the end surface 43c of the second side plate portion 43 are formed on the outer surface of the second side plate portion 43 of the lid 40 facing the end surface 43c of the second side plate portion 43. A protrusion 51 is protruded (see FIGS. 5 and 6). The formation position in the width direction Q of the pair of left and right first fitting protrusions 51 is the same position as the pair of recesses 48 formed outside the second side plate portion 43. On the other hand, a pair of first fitting holes 26 are formed at positions corresponding to the pair of first fitting protrusions 51 in the second side plate portion 25 of the box body 20 (see FIGS. 4 and 6).

  In addition, a second fitting projection 27 is provided at the center in the width direction Q of the outer side surface of the step bottom plate portion 23a of the box body 20 so as to correspond to the outer second side plate portion 43a of the lid body 40. Has a second fitting hole 52 (see FIG. 4). A third fitting protrusion 53 is formed along the slide insertion direction P on the outer surface of the pair of side plate portions 42 of the lid body 40 on the side opposite to the slide insertion side, and the correspondence between the pair of first side plate portions 24 of the box body 20. The portion is bulged outwardly to form a third fitting hole 28 (see FIGS. 4 and 5). Therefore, the pair of first fitting protrusions 51 of the second side plate portion 43 of the lid body 40 are inserted and fitted into the pair of fitting holes 26 of the second side plate portion 25 of the box body 20, respectively. In the state where the lid body 40 is assembled, the second fitting protrusion 27 of the box body 20 is inserted and fitted into the second fitting hole 52 of the lid body 40, and a pair of third fittings of the lid body 40 are performed. The protrusions 53 are inserted and fitted into the pair of third fitting holes 28 of the box body 20, and the box body 20 and the lid body 40 are integrated by a total of three fitting structures.

Also, as shown in FIGS. 4 to 9 (particularly FIG. 9), the plate thickness dimension of the second side plate portion 43 of the lid 40 from the inner side surface of each first side plate portion 24 in the bottom plate portion 23 of the box body 20. A pair of minute locking projections 29 protrude from the second side plate portion 25 at a position corresponding to the length (L ₁ ) of the first end face 42 a of the lid body 40. In the bottom plate portion 23, a pair of slits 31 are formed along the slide insertion direction P on both sides of the minute locking projection 29. Due to the presence of the pair of slits 31, the elongated portions along the slide insertion direction P in which the minute locking projections 29 in the bottom plate portion 23 are integrally formed are supported at both ends, and the minute locking projections 29 are connected to the bottom plate portion 23. On the other hand, it is easy to bend and deform when a force (F ₁ ) is applied perpendicularly. Further, as shown in FIGS. 5 and 8C, both end portions of the end surface 43c of the second side plate portion 43 of the lid body 40 in the longitudinal direction are provided in order to facilitate sliding insertion of the lid body 40 into the box body 20. The part is partially chamfered 43d. The width of the slit 31 is 1 mm or less. In FIG. 9, the control board V accommodated in the lid 40 is not shown.

When the lid 40 is slid into the box body 20, the first end surface 42 a of the first side plate 42 of the lid 40 is formed by the presence of the chamfer 43 d formed on the second side plate 43 of the lid 40. Then, it rides smoothly without being caught by the minute locking projections 29 of the bottom plate portion 23 of the box body 20. After that, when the above-described three fitting structure portions, in particular, the first fitting protrusions 51 on the slide insertion side of the lid body 40 are fitted into the first fitting holes 26 of the box body 20, the lid body The first end surface 42a of the first side plate portion 40 of the 40 rides over the minute locking projection 29, and the locking step portion 49 that is the boundary between the first and second end surfaces 42a, 42b and the minute locking projection 29 And lock. Further, by providing the slits 31 on both sides of the minute locking projection 29, the elongated portion along the slide insertion direction P in which the minute locking projection 29 is integrally formed on the bottom plate portion 23 is supported at both ends. 8 (b) and 8 (c), the box is formed to be easily bent due to elastic deformation when a vertical force (F ₁ ) is applied to the minute locking projection 29. When the lid body 40 is slid with respect to the main body 20 and assembled together, the lid body with respect to the box main body 20 does not cause a large catch even if the micro-engagement protrusion 29 is present due to the elastic deformation. 40 can be smoothly slid and inserted, and the first end face 42a of the first side plate portion 42 of the lid body passes completely, so that the portion of the minute locking projection 29 is restored to its original shape and there is no elastic deformation. After Tsu is a structure in which the engaging step portion 49 of the micro-retaining projection 29 and the lid 40 of the box body 20 is firmly locks. In the embodiment, the thickness (T ₁ ) of the bottom plate portion 23 of the box body 20 and the protruding height (T ₂ ) of the minute locking projections 29 are 2 mm and 0.8 mm, respectively [FIG. ]].

Moreover, an opening arm portion 63 constituting a sealing portion 60 described later is cut so that the box body 20 and the lid body 40 can be separated, and as shown in FIG. the cover 40 counter-sliding insertion direction P 'in an attempt to slide, when a force is applied (F ₂₎ in the top plate 41, a force (F ₂₎ an anti-sliding insertion direction P' completely parallel act as It is difficult to do. That is, the force (F ₂ ) applied to the top plate portion 41 of the lid 40 always generates a component force perpendicular to the top plate portion 41, and this vertical component force is related to the minute locking projection 29. It acts in the direction in which the stop step portion 49 is further locked. In general, since the substrate box B is made of a transparent body (typically, a transparent plastic such as polycarbonate), it can be recognized only through the lid 40 inside the box body 20 made of a transparent body. It is extremely difficult to visually confirm the presence of the protrusion 29. That is, it is difficult to understand the locking structure between the box body 20 and the lid body 40. Thus, the structural reason that the vertical component force of the force (F ₂ ) for removing the lid body 40 acts in the direction in which the minute locking projection 29 and the locking step portion 49 are further locked. And the reason that it is difficult to understand the locking structure between the box body 20 and the lid body 40, the opening arm 63 is temporarily cut, and the box body 20 and the lid body 40 can be separated. Even so, it is extremely difficult to remove the lid 40 from the box body 20.

  As shown in FIGS. 6, 7, and 10, a box-side sealing portion is provided at a central portion in the width direction Q of the second side plate portion 25 of the box body 20 and close to the bottom plate portion 23. A notch hole 62 is formed in a portion from which the 61 is protruded to reach the box side sealing portion 61 from the end surface of the second side plate portion 25. On the other hand, at a position corresponding to the second side plate portion 43 of the lid body 40, a lid body side sealing portion 64 protrudes through the opening arm portion 63, and the lid body 40 is assembled to the box body 20. The sealing portions 61 and 64 are integrally connected by a one-way screw 65. For this reason, when the electronic parts of the liquid crystal display control board V in the board box B are exchanged or inspected due to circumstances on the game hall side, the opening arm part 63 connected to the lid side sealing part 64 is cut along the cutting line. Cut by (M). On the other hand, even when an unauthorized person exchanges electronic parts of the control board V illegally, the opening arm 63 is first cut by the cutting line (M). Even if the lid 40 can be separated from the box body 20 by cutting the opening arm 63, the box body 20 is slid in the anti-sliding insertion direction P ′ relative to the box body 20. As described above, it is difficult to remove the lid 40 from the casing. Therefore, even if the opening arm 63 is cut, it is difficult to remove the lid 40 illegally. It should be noted that chamfers 43d formed at both ends of the end surface 43c of the second side plate portion 43 of the lid body 40 in order to facilitate sliding insertion of the lid body 40 into the box body 20 when the lid body 40 is removed from the box body 20. Since it does not contribute at all to the ease of removal, the reliability of the anti-fraud structure is not lowered.

  11A and 11B, before and after releasing the locking between the minute locking protrusion 29 of the box body 20 and the locking step 49 of the lid 40 by inserting the tool S into the tool insertion hole 54. It is sectional drawing which shows this state. In the state in which the lid 40 is assembled to the box body 20, as shown in FIG. 11 (a), the pair of recesses 48 formed on the outside of the second side plate portion 43 of the lid 40, and the box body 20 A tool insertion hole 54 is formed by the second side plate portion 25. For this reason, when the lid 40 is removed from the box body 20 due to circumstances on the game hall side, the rod-shaped tools S are inserted into the respective tool insertion holes 54, as shown in FIG. In addition, the tip of each tool S and the portion on the gripping side of the tip are respectively positioned on the outer side of the second side plate 43 of the lid 40 and on the end surface side on the inner side of the second side plate 25 of the box body 20. If each tool is squeezed simultaneously toward the outside of the substrate box B indicated by the arrow R in the state of being applied to the part, the lid 40 is lifted from the box body 20 without being squeezed left and right. A force only in the direction acts. As a result, as shown in FIG. 11 (b), the locking step portion 49 of the lid body 40 easily gets over the minute locking projection 29 of the box body 20, and the locking of both 29, 49 is released. Thus, the lid 40 can be easily removed from the box body 20.

Further, as shown in FIGS. 1 to 3, the substrate box B in which the lid body 40 is integrally assembled to the box body 20 is an outer surface of the second side plate portion 25 of the box body 20, and is formed on the end surface thereof. A pair of locking claws 32 formed integrally with the facing portion at a predetermined interval, and a locking claw formed on the outer surface of the outer second side plate portion 43a of the lid 40 and facing the end surface thereof It mounted on the back side of the liquid crystal display control board holder H ₁ via the 55. Locking claw 55 of the lid 40 is superimposed on the control board holder H ₁ box mounting surface 12 a U-shape of the engaging pieces 14 formed in proximity to, both 55,14 are separate coupled together by the slide coupling member 15 of the lower end portion of the substrate box B is mounted integrally with the substrate holder H _1. The upper end portion of the substrate box B, by the pair of locking claws 32 are engaged with the locking hole 16 formed in the substrate holder H ₁ (see FIG. 2), integral with the substrate holder H ₁ Mounted.

When the substrate box B is attached to the back surface of the substrate holder H ₁ as described above, the liquid crystal display device A attached to the front surface of the box body 20 faces the game board as shown in FIG. It is arranged so as to greatly enter the center of the game area 2 on the back side. Note that the game area 2 is formed inside the guide rail 3, a decorative frame 4 is formed at the center of the game area 2, and the liquid crystal display device A is disposed at the central part of the decorative frame 4. . A start winning opening 5 for starting the liquid crystal display device A by entering a ball is provided immediately below the liquid crystal display device A as viewed from the player. In addition, when the liquid crystal display device A starts symbol variation due to winning at the start winning opening 5 and the symbol display when the display is stopped after a predetermined time has passed in a specific display mode, the “big hit game” is started. At the time of this “big hit game”, a big prize opening device (attacker device) 7 in which the open / close door 6 opens to the front side to form a big prize opening is arranged immediately below the start winning prize opening 5.

In FIG. 2 and FIG. 3, the main control board holder of H ₂ substrates box accommodating the main control board in the rear (both not shown) is mounted, further to both sides of a liquid crystal display control board holder H ₁ is Further, another substrate box is attached, and a back cover (not shown) is attached so as to cover each substrate box.

  Moreover, in the said Example, this invention was implemented with respect to the board | substrate box B which accommodates the liquid crystal display control board | substrate V for controlling the liquid crystal display-type liquid crystal display apparatus A, Comprising: The board | substrate box B is comprised. A substrate box characterized in that the liquid crystal display device A is integrally attached to the front side of the box body 20, but a control board is housed inside and the box body and the lid can be separated by cutting the sealing portion If so, the present invention can naturally be applied to a substrate box that accommodates other control substrates such as a main control substrate and a dispensing device control substrate.

  Further, the box body 20 and the lid body 40 have a structure in which the lid body 40 is accommodated inside the box body 20, and the other fitting protrusion is inserted and fitted into one fitting hole and assembled. If so, the specific fitting structure by the fitting hole and the fitting protrusion is not limited to the above-described one, and various conceivable structures are conceivable.
