Description

  In the present invention, for example, in a gaming machine such as a pachinko machine or a slot machine, the gaming machine device disposed in the internal space surrounded by the shielding members inside the housing is contacted without a proper procedure (that is, The present invention relates to a connecting structure of shielding members for gaming machines that can prevent fraud.

  Conventionally, in gaming machines such as pachinko machines and slot machines, it is well known that there is a fraudulent act (so-called goto act) in which a wiring is intentionally short-circuited or a board is replaced with a fraudulent one. And in order to prevent this, the structure which is disclosed by patent document 1, for example is proposed.

  Patent Document 1 covers a wiring connection portion in a wiring connector and a terminal vicinity portion of a plurality of wirings extending therefrom, and is coupled so as to face each other so that the wiring connection portion can be fitted thereto, From two split covers in which a bundling insertion portion for bundling and inserting a plurality of wires, and a side trapezoidal covering portion covering the outer peripheral portion between the fitting portion and the bundling insertion portion are formed. A cover is disclosed. The divided cover is provided with an elastic engagement claw and an engagement hole that are engaged with each other, and two divided covers are engaged by the engagement of the elastic engagement claw and the engagement hole. Are combined to face each other.

  Patent Document 2 covers the periphery of a connector plug that is fitted to a connector plug seat attached to a circuit board and is connected to a cable for electrically connecting the circuit board and an external board. A protective cover for protecting the connector plug is disclosed. Such a protective cover has a structure that cannot be removed from the board case unless the upper cover covering the connector plug fitted to the connector plug seat is broken.

JP 2005-342406 A JP 2012-95930 A

  However, since the split cover described in Patent Document 1 has a configuration in which the elastic engagement claws are exposed to the outside over almost the entire area, for example, by elastically deforming the elastic engagement claws directly with a finger, The engagement between the elastic engagement claw and the engagement hole can be easily released. For this reason, there is much room for improvement in terms of preventing fraud.

  Further, since the protective cover described in Patent Document 2 cannot be removed from the substrate case unless the upper cover is destroyed, it has a high effect of preventing fraud, but it is a valid reason, for example, during normal maintenance work. Even when it becomes necessary to remove the protective cover, the upper cover has to be destroyed, and there is a problem that the material cost and the work load required for the destruction are extremely large.

  Therefore, in view of the above-described problems, the present invention provides a shielding for gaming machines capable of suppressing an increase in material costs and a burden of maintenance work after sufficiently securing an effect of preventing illegal acts. The object is to provide a member coupling structure.

  The present invention has been made for the purpose of solving the above-described problems, and has an inner space surrounded by both shielding members that have a first shielding member and a second shielding member that are detachably coupled to each other. A shielding member coupling structure for gaming machines that prevents illegal acts on gaming machine devices arranged in the at least one of the first shielding member and the second shielding member, and is elastically deformable in a predetermined direction. A connecting projection is provided, and a claw is formed in a protruding shape at the tip of the connecting projection, and the other shielding member is provided with the claw on the shielding member provided with the connecting projection. A stepped portion is provided, and the claw portion is engaged with the stepped portion so that both shielding members are joined, and the connecting projection is elastically deformed to release the locked state of the claw portion. And both shielding members can be separated, and further, the first shielding member and the second shielding portion At least one of them is provided with a covering portion that covers the claw portion locked to the step portion from the outside, and the covering portion is provided with a maintenance opening facing the claw portion in a penetrating manner. A shielding for gaming machines, wherein a gap is formed between the entire claw portion and the inner wall surface of the covering portion, so that the entire claw portion and the covering portion are not in contact with each other. It is a member coupling structure.

  In the present invention, the first shielding member and the second shielding member may be constituted by cover members having the same shape, for example, or, for example, one shielding member is a substrate case body, and the other shielding member. May be used as a cover member attached to the substrate case main body. Further, the gaming machine device itself may be surrounded by both shielding members or may be partially surrounded. Further, as a mechanism for coupling the first shielding member and the second shielding member to each other, a single connection structure or a plurality of connection structures may be provided.

  In such a configuration, since the claw portion of the connection protrusion locked to the stepped portion is covered with the covering portion, for example, it is possible to prevent the connection protrusion from being operated from the outside by a wire or the like. it can. Furthermore, since the cover is provided with a maintenance opening, a tool or the like is inserted through the maintenance opening toward the claw of the connection protrusion, so that the claw is properly locked. It can cancel | release and can open | release both shielding members suitably. In such work, since it is not necessary to destroy the required member, the material cost is not wasted and a great work load required for the destruction is not generated. Further, even if a fraudulent act is performed through the maintenance opening, scratches and the like at the time of the fraudulent activity remain as traces on the inner wall surface of the covering portion, so that it is easy to take measures to prevent the fraud. Further, by forming a gap between the inner wall surface of the covering portion and the entire claw portion that is locked to the stepped portion, the covering portion is pressed directly from outside to press the covering portion. It is possible to cope with an illegal act that attempts to unlock the claw part by bending because the gap appropriately absorbs the bending of the covering part.

  Moreover, in this invention, each shielding member which has the said coating | coated part and the said connection protrusion is especially effective when it is an integrally molded article comprised with the elastic material.

  That is, in order to suitably elastically deform the connection protrusion, the shielding member is integrally formed of an elastic material having good elastic performance, while the covering portion is also elastically deformable. Therefore, there exists a possibility that the fraudulent act which bends this coating | coated part directly as mentioned above will become easy. However, as in the above configuration, by arranging a gap between the entire claw portion and the inner wall surface of the covering portion so that the entire claw portion and the covering portion are not in contact with each other, Even if there is an illegal act of pressing and bending the covering portion, it is possible to suitably prevent the inner wall surface of the covering portion from reaching the claw portion.

  Since the shielding member coupling structure for gaming machines of the present invention includes a covering portion that covers the claw portion that is locked to the stepped portion, it is extremely difficult to release the coupling between the shielding members, and the anti-fraud effect is high. Has an excellent effect. In addition, when releasing the connection for a valid reason such as maintenance work, there is no need to destroy the member, so that there is an effect that the material cost does not increase and the work load required for the destruction does not occur. There is. In addition, even if there is an illegal act of pressing and bending the covering portion, it is possible to suitably prevent the inner wall surface of the covering portion from reaching the claw portion.

And used in a coupled state.

  In the present embodiment, one cover body 19 is the first shielding member according to the present invention, and the other cover body 19 is the second shielding member according to the present invention. As described above, the cover body 19 as the first shielding member and the cover body 19 as the second shielding member have the same case shape, and the same reference numerals are given in the present embodiment. explain.

  More specifically, as shown in FIGS. 5 to 8, the upper end portion of the cover body 19 is a recess that becomes a hole 29 into which the wiring cord X is inserted when the cover member 20 is combined with each other. 30 are each provided along the up-down direction.

  Further, the pair of cover bodies 19, 19 are provided with a cover body coupling structure 10 for releasably coupling with each other. More specifically, the cover body 19 is provided with connection protrusions 31 and 32 protruding in the left-right direction toward the other cover body 19 to be combined. Specifically, the lower connection projection 31 is provided on one of the side walls facing the front and rear of the cover body 19, and the upper connection projection 32 is provided on the other side at a position above the lower connection projection 31. ing. Both connection protrusions 31 and 32 are both long and thin plate-like, and have a structure that can be elastically deformed in the front-rear direction.

  Furthermore, claw portions 31a and 32a projecting outward are provided at the tip portions of the connection projections 31 and 32, respectively. Moreover, the front-end | tip part of each connection protrusion 31 and 32 becomes a pointed shape which becomes thin toward the front-end | tip, and the inclined surfaces 31b and 32b are formed in this site | part.

  As shown in FIGS. 5 and 6, shallow groove portions 33, 34 into which the connection projections 31, 32 provided on the other cover body 19 are inserted in the cover body 19 in the left-right direction. It is provided along. Specifically, in the other cover body 19, a lower groove portion 33 is provided at a position corresponding to the lower connection projection 31 of the one cover body 19, and An upper groove 34 is provided at a position corresponding to the upper connection protrusion 32. Further, step portions 33a and 34a to which the claw portions 31a and 32a of the connection projecting portions 31 and 32 can be respectively locked are provided in the groove portions 33 and 34, respectively.

  Further, in the cover bodies 19 and 19, a convex portion 35 a and a concave portion 36 a are respectively provided on end surfaces that are brought into contact with each other when they are coupled to each other. And when this cover bodies 19 and 19 couple | bond together, it has the structure where the convex part 35a of one cover body 19 and the recessed part 36a of the other cover body 19 mutually fit.

  A guide surface 37 that abuts on the upper surface 22 of the connector body 18 is provided on the inner peripheral surface of the lower portion of the cover body 19. Furthermore, a connector body locking claw portion 40 that is inserted into and fitted into the insertion groove portion 39 of the connector body 18 is provided below the guide surface 37. Specifically, the connector body locking claw portions 40 are respectively extended inward along the left-right direction on the front and rear side walls of the cover body 19.

  Further, on the left and right outer surfaces of the cover body 19, non-slip protrusions 28, 28 protruding in a direction substantially perpendicular to the direction in which the connector 12 is pulled out are provided at substantially intermediate positions. . The anti-slip protrusion 28 functions as a finger hook that prevents the operator's finger from slipping away from the operation portion 25 when the connector 12 is pulled out from the receptacle 11.

  The cover body 19 is preferably made of an elastic material such as PC (polycarbonate), PS (polystyrene), ABS (acrylonitrile-butadiene-styrene copolymer synthetic resin, or PMMA (polymethyl methacrylate resin). By adopting such a transparent resin material, the internal wiring can be visually recognized, so that the anti-fraud performance is excellent.

  When the cover bodies 19, 19 are attached to the connector body 18, first, the guide surface 37 of the cover body 19 is brought into contact with the upper surface 22 of the connector body 18, and the connector of the cover body 19 is connected. The connector body 18 is sandwiched from the left and right sides by the pair of cover bodies 19 and 19 while the main body locking claw portion 40 is fitted in the insertion groove portion 39 of the connector body 18 and coupled to each other in an opposing state (FIG. 3 etc. reference).

  Specifically, as shown in FIG. 8, the lower connection protrusion 31 and the upper connection protrusion 32 of one cover body 19 are connected to the upper groove 34 and the lower groove 33 of the other cover body 19. As shown in FIG. 9, the claw portions 31 a and 32 a of the connection protrusions 31 and 32 provided on one cover body 19 and the groove portions 33 and 34 provided on the other cover body 19 are respectively inserted. The stepped portions 33a and 34a are locked.

  Further, in such a coupled state, the convex portion 35a of one cover body 19 and the concave portion 36a of the other cover body 19 are fitted to each other, and rattling of the pair of cover bodies 19 and 19 is suppressed. Further, it is possible to prevent a gap from being generated in the joint portion between the cover bodies 19 and 19 due to distortion or the like.

  Next, the cover body coupling structure 10 which is a main part will be further described in detail. In the description of the cover body coupling structure 10, the coupling portion between the lower connection projection 31 and the lower groove 33 will be described as an example. Of course, the upper connection projection 32, the upper groove 34, and The structure of the binding site is the same. Therefore, the description about the coupling | bond part of the said upper side connection protrusion 32 and the said upper side groove part 34 shall be abbreviate | omitted.

  As shown in FIGS. 5 and 6, a front surface formed on the outer peripheral surface of the cover body 19 so as to protrude from the outer peripheral surface at a portion corresponding to the position of the step portion 33 a of the lower groove portion 33. A covering portion 33b having a substantially rectangular shape as viewed is provided. In other words, the covering portion 33b has a function of covering the claw portion 31a locked to the stepped portion 33a from the outside as shown in FIG.

  Further, as shown in FIG. 10, the covering portion 33b is provided so as to be separated from the entire claw portion 31a locked to the stepped portion 33a. A gap S is formed between the claw portions 31a in the locked state.

  Further, as shown in FIG. 5 and the like, a longitudinal slit-like maintenance opening 44 is provided in a penetrating manner at a position facing the outer peripheral surface of the cover body 19 in the covering portion 33b. The maintenance opening 44 communicates with the gap S via a tool insertion passage 50 to be described later, whereby the maintenance opening 44 faces the claw portion 31a that is locked to the stepped portion 33a. It has become. With this configuration, a maintenance tool T, which will be described later, can be inserted through the maintenance opening 44 toward the claw portion 31a.

  Here, the maintenance opening 44 opens in the left-right direction with reference to the cover body 19. That is, the elastic deformation direction of the lower connection protrusion 31 is the front-rear direction with respect to the cover body 19, the opening direction of the maintenance opening 44 and the elastic deformation of the lower connection protrusion 31. Since the directions are orthogonal to each other, they are different from each other.

  As shown in FIG. 10, a tool insertion passage 50 is provided on the maintenance opening 44 side of the gap S. The tool insertion passage 50 is configured by a region surrounded by the inner wall surface 46 of the covering portion 33 b and the outer peripheral surface 48 of the cover body 19 that are arranged to face each other. In the tool insertion passage 50, the outer peripheral surface 48 of the cover body 19 is inclined with respect to the inner wall surface 46 of the covering portion 33b so that the opening area increases toward the maintenance opening 44 side. Is formed. Specifically, the innermost passage width W2 of the tool insertion passage 50 and the opening width W1 of the maintenance opening 44 are dimensioned so as to satisfy the relationship W1> W2.

  Further, the outer peripheral surface 48 of the cover body 19 in the tool insertion passage 50 is continued to the outer peripheral surface 52 around the maintenance opening 44 while maintaining the inclination angle. That is, the outer peripheral surface 52 around the maintenance opening 44 is formed to be inclined toward the center side of the cover body 19 as the distance from the tool insertion passage 50 increases.

  In the cover body coupling structure 10 described above, when the pair of cover bodies 19 and 19 are coupled to each other, the locked claw portion 31a is covered from the outside by the covering portion 33b. Therefore, for example, as shown in FIG. 12, it is extremely difficult for a wire or the like that has entered due to an illegal act to reach the claw portion 31 a, and the claw portion 31 a is locked when the lower connection projection 31 is illegally operated. It is prevented that the state is released. Furthermore, since the opening direction of the maintenance opening 44 and the elastic deformation direction of the lower connection projection 31 are different, even if a wire or the like is inserted from the maintenance opening 44 in the left-right direction, Thus, it is extremely difficult to elastically deform the lower connection projection 31 in the front-rear direction.

  Further, a gap S is provided between the entire claw portion 31a in the locked state and the inner wall surface 46 of the covering portion 33b, and the entire claw portion 31a and the inner wall surface 46 of the covering portion 33b are not in contact with each other. Therefore, as shown in FIG. 12, there is an act of temporarily pressing the covering portion 33b from the outside to bend the covering portion 33b and operating the claw portion 31a via the covering portion 33b. Even if it was made, since the gap S appropriately absorbs the bending of the covering portion 33b, it is possible to suitably prevent an unauthorized operation on the claw portion 31a. In order to suitably deform the connection projection 31 elastically, the cover body 19 is integrally formed of an elastic material having a good elastic performance. On the other hand, the covering portion 33b can also be elastically deformed. Therefore, there is a risk that an illegal act of directly bending the covering portion 33b as described above may be facilitated. However, by temporarily arranging the gap S between the entire claw portion 31a and the inner wall surface 46 of the covering portion 33b so that the entire claw portion 31a and the covering portion 33b are not in contact with each other, Even if there is an unauthorized act of pressing and bending the covering portion 33b, it is possible to suitably prevent the inner wall surface 46 of the covering portion 33b from reaching the claw portion 31a. Even if a fraudulent act is performed through the maintenance opening 44, scratches and the like at the time of the fraudulent action remain as traces on the inner wall surface 46 of the covering portion 33b. There are advantages.

  On the other hand, in the case of maintenance work of the connector main body 18, when the coupled cover bodies 19, 19 are properly separated, as shown in FIG. 11, a long tool T such as a screwdriver is provided from the maintenance opening 44. The tool T is pushed in while the inclined surface 31b formed at the tip of the lower connection projection 31 is brought into contact with the tip of the tool T, and the lower connection projection 31 is preferably moved backward. Elastically deform. Thereby, the latching state of the nail | claw part 31a is cancelled | released easily.

  Here, since the tool insertion passage 50 is configured so that the opening area becomes larger toward the maintenance opening 44 side, a tool T such as a screwdriver is easily inserted as shown in FIG. In addition, the inner wall surface 46 of the covering portion 33b constituting the tool insertion passage 50 and the outer peripheral surface 48 of the cover body 19 serve as a guide surface for assisting in and out of the tool T. Further, since the outer peripheral surface 52 around the maintenance opening 44 is inclined toward the center side of the cover body 19 as it is away from the tool insertion passage 50, the space around the outer peripheral surface 52 is enlarged, and the tool T When the tool T is inserted into the maintenance opening 44, the operability of the tool T is further improved.

  In addition, an inclined surface 31b with which the tip of the tool T abuts is provided at the tip of the lower connection projection 31, and the inclined surface 31b is the maintenance object with respect to the axis of the lower connection projection 31. It is formed so as to be inclined at an angle so as to face the opening 44 for use. Thereby, the tip shape of the lower connection projection 31 is a pointed shape in which the angle formed by the tip surface of the lower connection projection 31 and the inclined surface 31b is an obtuse angle. As shown in FIG. 11, the tool T is inserted through the maintenance opening 44, and the tool T is inserted along the opening direction of the maintenance opening 44 as it is, and the tip of the tool T and the inclined surface 31b are inserted. And the lower connecting projection 31 can be easily elastically deformed backward by simply pressing the inclined surface 31b with the tip of the tool T, and the claw portion 31a can be locked. The state can be easily released. As shown in FIG. 11 and the like, the inner wall surface 46 of the covering portion 33b and the inclined surface 31b of the claw portion 31a of the connection protrusion 31 face each other and further toward the maintenance opening 44. Accordingly, even if the cover portion 33b is pressed from the outside and the tip of the cover portion 33b is bent toward the claw portion 31a as shown in FIG. Since the separation distance between the inner wall surface 46 and the inclined surface 31b is sufficiently ensured by the above-described inclination mode, the structure is difficult to interfere with each other.

  In addition, the series of maintenance operations described above do not need to be performed by destroying a specific member, so that there is no extra material cost and no work burden is required for the destruction.

  The above-described example is naturally applicable to the cover body coupling structure 10 including the covering portion 34b. Note that the cover member coupling structure 10 described so far constitutes the shielding member coupling structure for gaming machines according to the present invention.

  The cover member 20 in the above-described embodiment is configured by a pair of cover bodies 19 and 19 having the same shape, but instead, members having different shapes are combined to form a cover member. But of course. Furthermore, in order to couple | bond a pair of cover bodies 19 and 19, the single or several cover body coupling | bonding structure 10 may be employ | adopted. In addition, the said cover part 34b may be provided in both the cover bodies 19 and 19, and may be provided only in the cover body 19 of one side.

  For example, as shown in FIG. 13, a configuration may be adopted in which a concave notch 31 d with which the tool T abuts is provided at the tip of the lower connection projection 31. In such a configuration, the front end of the tool T is brought into contact with the notch 31d, and the tool T is moved to the front side with the inlet end 46x formed in the covering portion 33b as a fulcrum (in FIG. 13). The claw portion 31c can be released from the locked state by turning the upper connection projection 31 and elastically deforming the lower connection projection 31 rearward.

Further, as shown in FIGS. 14 and 15, still another embodiment is proposed.
In this configuration, as shown in FIG. 14a, a cover member 61 (see FIG. 14b) as a second shielding member is covered from above the substrate case main body 60 as the first shielding member to cover the internal substrate (not shown). It is a structure to store.

  In this configuration, the substrate case main body 60 is provided with a covering portion 64 having a maintenance opening portion 63 opened in the front-rear direction, and a step portion 62 (see FIG. 14 b) is provided in the covering portion 64. It has been.

  On the other hand, a connecting projection 65 is provided at the end edge of the cover member 61 and is elastically deformed in the left-right direction. The connecting projection 65 is engaged with the stepped portion 62 at the tip. A possible claw 66 is provided. In addition, the claw portion 66 is formed with an inclined surface 67 as a contact surface.

  In such a configuration, as shown in FIGS. 15a and 15b, the tool T is inserted into the covering portion 64 from the maintenance opening 63, and the tip of the tool T is brought into contact with the inclined surface 67 to thereby The connection protrusion 65 is elastically deformed, and the locked state between the claw portion 66 and the stepped portion 62 can be easily released. Further, this configuration also has a high fraud prevention effect because the elastic deformation direction of the connection protrusion 65 and the opening direction of the maintenance opening 63 are orthogonal to each other and are different from each other. Further, by forming a gap S between the entire claw portion 66 locked to the stepped portion 62 and the covering portion 64 so that they are not in contact with each other, the covering portion 64 is directly connected from the outside. By pressing and bending the covering portion 64, it is possible to prevent an illegal act to release the locking of the claw portion 66.

  The opening direction of the maintenance openings 44 and 63 described above is not limited to a specific direction and may be another direction. However, in consideration of prevention of dust mixing and workability during maintenance, it is desirable that the distance is determined in the left-right direction under normal use. Moreover, the arrangement positions of the maintenance openings 44 and 63 can be changed as appropriate.

  Moreover, the material of each member which comprises the cover body coupling structure 10 is not specifically limited, For example, it may be comprised with the same synthetic resin material, and the different synthetic resin materials are combined and used. May be. For example, only the connection protrusions 31, 32, 65 may be made of a metal material. From the viewpoint of preventing fraud, it is desirable that the member constituting the shielding member according to the present invention is made of a transparent material that allows the inside to be seen through.

  In addition, the present invention is not applied only to the connector 18 and the board connected to the power supply device 3, and may be applied to other parts to deal with fraud.

  Further, the present invention is not limited to the slot machine 1 and may be applied to other gaming machines such as so-called pachinko machines and parrot machines.
