Description

  The present invention relates to a connector for a gaming machine used for a main board for controlling a gaming machine such as a revolving gaming machine or a pachinko machine called a pachislot machine, and more specifically, a gaming machine connector having a function for preventing unauthorized modification, In particular, the present invention relates to a protective device for the connector, a control board including the connector, and a gaming machine.

  In recent years, not only pachinko machines but also pachinko machines called pachislot machines have been actively used in conventional pachinko halls and pachislot halls. In these gaming machines, the winning probability is governed by the information in the ROM mounted on the control main board. For this reason, ensuring security for the main board for control is a serious technical issue regardless of the model.

  In other words, in this type of gaming machine, since the inside of the equipment needs to be operated frequently, the front door is opened and closed by the front door, so the main board for control in the equipment will be exposed to human eyes. Become. For this reason, in order to deal with the illegal actions such as remodeling of the main board for control (replacement of ROM, etc.) continuously, the mounting apparatus for the main board for control has various measures for preventing unauthorized modification. Ingenuity is taken.

  FIG. 4 shows a typical board mounting apparatus that has been devised to prevent unauthorized modification. The board mounting apparatus shown here is for mounting a control main board on the surface of a back plate of a cabinet of a gaming machine, a relatively thin board case 10 for housing the main board, and a board case 10 And a case holder (not shown) for fixing to the back plate.

  The substrate case 10 includes a rectangular base 11 that holds a rectangular main substrate in front, and a rectangular cover 12 that is attached to the base 11 so as to cover the main substrate held by the base 11. All are made of transparent resin so that the substrate can be seen. The cover 12 is sealed and fixed to the base 11 by an engaging portion on the lower side and a plurality of caulking pins 13 attached to both sides of the upper side in order to enclose the main substrate in the substrate case 10.

  The substrate case 10 in which the main substrate for control is enclosed is fixed to the case holder by a plurality of protrusions provided on the lower side portion of the case holder and a plurality of caulking pins 14 held at the center portion of the upper side of the substrate case 10. Is done.

  The main board for control has a plurality of connectors 20 on the front surface of the lower edge for electrical connection with an external circuit. As shown in FIG. 5, each connector 20 is a commercially available product (for example, 8825E (R) series manufactured by KEL Co., Ltd.), a plug 21 mounted on the surface of the main board, and a jack 22 inserted into the plug 21. (Generally called a receptacle). The plug 21 is a rectangle that is long horizontally, and protrudes from the horizontally long opening 15 provided in the cover 12 of the substrate case 10 to the front side of the cover 12 in order to receive the jack 22.

http://www.kel.jp/product/cate_conn/bc_conn/8825e.pdf

  The jack 22 is a horizontally long rectangular block corresponding to the plug 21, and is connected to the distal end portion of the belt-shaped harness 30. The jack 22 is inserted into the plug 21 and electrically connected to the plug 21. In order to fix the jack 22 in the inserted state, the jack 22 is equipped with rotational fixing claws 23 and 23 on both sides. The fixing claws 23 and 23 are rotated from the released state to the locked state by inserting the jack 22 into the plug 21. The jack 22 can be pulled out of the plug 21 by pinching the fixing claws 23 and 23 from both sides to operate from the locked state to the released state.

  A similar substrate mounting apparatus in which a substrate case and a case holder are combined is also described in Patent Document 1, for example.

JP 2001-170255 A

  According to such a substrate mounting apparatus, the substrate case 10 cannot be removed from the case holder and the substrate case 10 cannot be opened unless the crimping seal portions by the crimping pins 13 and 14 are broken with a tool such as a nipper. And when the caulking seal part is destroyed with a tool such as a nipper, the trace remains clearly, and the trace can be found immediately when the game machine is opened. In addition, the surface of the internal control main board can be directly monitored through the transparent substrate case 10. As a result of these, fraudulent acts such as opening the substrate case 10 to work on the control main substrate or replacing the control main substrate together with the substrate case 10 are effectively prevented.

  However, as the security level for the control main board increases, fraudulent acts with different tricks have begun to rampant, one of which is fraudulent acts on the connector 20. For example, the main board for control is equipped with several connectors 20 for sending and receiving various signals, and via these connectors 20 and the harness 30, an operation unit of the gaming machine, a drum control unit, and an effect sub Connected to a substrate or the like. Since these connectors 20 need to be replaced when the control main board fails or is defective, the plug 21 and the jack 22 cannot be completely fixed so as not to be separated. It is exposed and attached to a place where it can be easily inserted and removed (in the above-mentioned main board, in front of the lower edge). For this reason, unauthorized actions such as separating the connector 20 without permission and interposing unauthorized parts between the plug 21 and the jack 22 are beginning to prevail.

  In short, since the mounting device as described above is developed for the control main board, the security level is also high, but the connector 20 can be inserted into and removed from the main board for replacement of the main board. It is attached to the current situation, and it is powerless against fraud. If the connector 20 has a non-separable structure, fraudulent activity can be prevented, but replacement with a new one is required each time the connector 20 is separated, and a great burden is imposed both in terms of labor and cost.

When the protective cover is attached to the fixed base, the stopper is positioned inside the operation portion that is opened outward when the protective cover and the fixed base are connected and fixed.

  In the gaming machine connector provided with the protector of the present invention, when a fixing base is attached to the plug mounted on the surface of the control board, and the jack is inserted into the plug and fixed in this state, the jack fixed to the plug By this, the fixing base is fixed to the plug. If a protective cover is attached to the fixed base, the plug and jack are covered and protected by the fixed base and the protective cover. The protective lid cannot be removed from the fixed base unless it is destroyed, and if it is destroyed, its trace remains clearly. For this reason, illegal acts on the connector are prevented.

  When it is necessary to separate the connector on the side of the gaming machine manufacturer or the hall, such as replacement of the control board, the protective lid is destroyed. Thereby, the protective lid is separated from the fixed base. When the protective cover is removed, the connector is exposed and the jack can be removed. When the jack is released, the fixed base is released from the restraint by the jack and is released from the plug. The protective lid or the protective lid and the fixing base are destroyed and cannot be reused, but the connector is not damaged, and can be used as it is in the next connection. In the next connection, a new fixing base and a protective cover are required. However, compared with the case where the plug and jack are replaced, the labor and cost required for the replacement are significantly reduced.

  Here, a commercial product can be used as the original connector, that is, the plug jack. The combination of a fixed base and a protective lid with a commercially available connector can dramatically improve the security level while enabling repeated use. It is one of the feature points.

  In order to confirm the state of the internal connector, the protective lid is preferably made of a translucent resin that allows the inside to be seen through. For the same reason, the fixing base is also preferably made of a translucent resin. .

When the connector is removed, the protective lid is destroyed. In order to facilitate this destruction, the protective lid preferably has a linear bulging portion that can be easily cut and separated by a nipper or the like as the planned destruction portion. Needless to say, even in this configuration, traces of destruction remain clearly on the protective lid. Rather, by intentionally forming the part to be destroyed, it is easy to determine whether or not there is destruction.
It is preferable that the linear bulging portion, which is a planned destruction portion, be provided at the central portion that bisects the protective lid on both sides. Thereby, a protective cover can be easily divided into both sides for 2 minutes, and the removal from a fixed stand becomes easy.

  The fixed base is locked at a fixed position by a jack inserted and fixed in the plug, but a harness connected to the jack can also be used as a locking portion for fixing the fixed base in the mounted state. By using the harness, it is possible to securely fix the fixing base to the jack with a simple configuration.

  The protective lid preferably has a stopper that holds the fixing claw provided in the jack in a locked state. According to this configuration, even if an outsider tries to operate the fixing claw of the jack to the released state by making a hole in the protective cover, the operation to the released state is prevented. Further, when an external force in the detaching direction is applied to the fixed base, an external force in the releasing direction may be applied to the fixing claw of the jack, but the operation of the fixing claw in the releasing direction is blocked. As a result, the security level of the connector can be effectively increased.

  The fixing base and the protective cover can be used upside down according to the direction of the plug and jack.

  A gaming machine connector equipped with the protector of the present invention is a fixed base fixed to a jack of a control board using a plug, and is detachably coupled to the fixed base, and can be broken and broken. By combining the protective lid, which is separated from the fixed base only by the original connector, with the original connector, it is possible to repeatedly use the connector of the control board, and to reliably prevent unauthorized acts on the connector, and to ensure safety Both economics and economy can be significantly increased. Further, it can be applied to a commercially available connector, and its security level can be easily improved.

  In particular, since the protector for the connector for gaming machines is provided with an ear portion that covers the upper part of the other connector mounted on the control board on the fixing base of the frame body that is externally fitted and surrounds the plug, It is possible to take countermeasures against the gaming machine connector and the nearby connector at the same time.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a three-side view of a connector for a gaming machine showing an embodiment of the present invention, FIG. 2 is an explanatory view of an assembling procedure of the connector, and FIG. 3 is an explanatory view of an exploded procedure of the connector.

1st Example (fixing stand without the ear | edge part):
The gaming machine connector according to the present embodiment is used for a control main board 40 of a pachislot machine as a gaming machine, as shown in FIGS.

  Similar to the substrate case shown in FIG. 4, the control main substrate 40 is enclosed in the substrate case 10 in order to prevent fraudulent acts on the main substrate. The board case 10 is detachably attached to the surface of the case holder attached to the surface of the back plate of the gaming machine cabinet by a fixing pin.

  The substrate case 10 includes a rectangular attachment base 11 that holds a rectangular main substrate 40 on the front surface, and a rectangular cover 12 that is attached to the base 11 so as to cover the main substrate 40 held on the attachment base 11. Yes. Both the base 11 and the cover 12 are formed of a transparent resin so that the internal main substrate can be seen. The cover 12 is sealed and fixed to the base 11 by an engaging portion on the lower side and a plurality of caulking pins attached to both sides of the upper side in order to enclose the main substrate in the substrate case 10. The substrate case 10 is fixed to the case holder by a plurality of protrusions provided on the lower side portion of the case holder and a plurality of caulking pins held at the center portion of the upper side of the substrate case 10.

  The control main board 40 has a plurality of connectors 20 on the front surface of the lower edge for electrical connection with an external circuit. Each connector 20 is a commercially available product (KEL8825 series) and includes a plug 21 mounted on the surface of the main board and a jack 22 inserted into the plug 21. The plug 21 is a horizontally long rectangular resin block, and protrudes from the horizontally long opening 15 provided in the cover 12 of the substrate case 10 to the front side of the cover 12 in order to receive the jack 22.

  A jack 22 called “re-sector pull” (in particular, also including FIG. 5) is a horizontally long rectangular resin block corresponding to the plug 21, and is connected to the tip of the belt-shaped harness 30. Inserted and electrically connected to the plug 21. In order to prevent inadvertent detachment of the jack 22, the jack 22 is equipped with rotating fixed claws 23, 23 on both sides. The fixed claws 23, 23 on both sides have claw portions 24, 24 on the front end side of the vertical rotation fulcrum and operation portions 25, 25 on the near side, respectively, and the operation portion 25 with the jack 22 not inserted. , 25 are pushed inward, and the claw portions 24, 24 are opened outward. When the jack 22 is pushed into the plug 21 from this state, the claw portions 24, 24 on the distal end side are closed inward, and the operation portions 25, 25 on the near side are opened outward. When the claw portions 24, 24 on the front end side are closed inward, the jack 22 is fixed to the plug 21 so as not to be detached. In this state, when the front side operation portions 25 and 25 are pushed inward, the claw portions 24 and 24 on the front end side are opened to the outside and detached from the plug 21, and the jack 22 can be detached from the plug 21.

  Such a connector 20 is combined with a fixing base 50 fixed to the connector 20 and a protective lid 60 attached to the fixing base 50 in order to prevent fraud. The fixed base 50 and the protective lid 60 are made of a transparent resin so that the state of the internal connector 20 can be visually recognized from the outside.

  The fixing base 50 is a rectangular frame that surrounds the plug 21. The fixing base 50 has a rectangular main body 51 that fits into the plug 21 and a square frame-shaped protective portion 52 that is integrally provided outside the main body 51 so as to surround the rear portion of the main body 51. Protrusions 53 for locking the protective lid 60 are respectively provided on the rear outer surface of the main body 51, particularly on both sides of the upper surface and both sides of the lower surface. The protection part 52 surrounds the rear part of the main body part 51 leaving the lower center part, and is integrated with the main body part 51 at the rear end part. The reason why the lower central portion is an open portion is to form an opening for drawing the harness 30 to the outside.

  The fixing base 50 is externally fitted to the plug 21 of the connector 20, and the jack 22 is attached to the plug 21 in this state, so that the fixing base 50 is fixed to the connector 20. Specifically, it is mainly prevented by the jack 22 inserted into the plug 21, particularly the harness 30 connected to the jack 22. More specifically, the end portion of the harness 30 is bent in an inverted U shape and fixed to the jack 22, and the tip portion protrudes below the jack 22 and the bent top portion 31 protrudes above the jack 22. . The fixing base 50 externally fitted to the plug 21 is mainly prevented from being detached by the bent top portion 31 of the harness 30 protruding upward from the jack 22 attached to the plug 21, particularly the jack 22, and is fixed to the connector 20. . Further, the operation portions 25, 25 opened to the outside of the fixing claws 23, 23 on both sides and the tip end portion of the harness 30 protruding downward from the jack 22 also contribute to preventing the fixing base 50 from coming off.

  The protective lid 60 is a long rectangular cap-shaped resin body that is connected and fixed to the rectangular fixing base 50 and covers the connector 20. A plurality of openings 61 into which the protrusions 53 of the fixing base 50 are fitted are provided on the outer surface of the rear portion of the protective lid 60, particularly on both sides of the upper surface and both sides of the lower surface. In these drawings, the fixing base 50 is provided with the protrusion 53 and the protective lid 60 is provided with the opening 61. Conversely, the fixing base 50 is provided with the opening 61 and the protective lid 60 is provided with the protrusion 53. However, there is no problem and the same effect is obtained (not shown).

  At the rear part of the lower surface side of the protective lid 60, a notch part that is long horizontally is provided, leaving both side parts. The notch 62 forms an opening for drawing the harness 30 to the outside in cooperation with the opening of the fixed base 50.

  A linear bulge 63 is received at the center of the protective lid 60. The linear bulging portion 63 is a curved portion having a semicircular shape with an outward cross section, and is provided on the upper surface portion, the front surface portion, and the lower surface portion of the protective lid 60 so that the right and left sides of the protective lid 50 are divided into two. It has been. The bulging portion 63 can be easily excised with a nipper or the like. By this excision, the protective cover 60 is divided into left and right parts. A pair of stoppers 64, 64 on both sides are provided on the front portion of the protective lid 60. The stoppers 64, 64 are rods projecting from the back side of the front part to the back side, and the operation part opened to the outside of the fixing claws 23, 23 on both sides of the jack 22 in a state where the protective cover 60 is attached to the fixing base 50. It is located inside 25 and 25, and prevents operation parts 25 and 25 from moving inside. As a result, the jack 22 is kept fixed to the plug 21.

  Next, the usage method and function of the connector for gaming machines according to the present embodiment will be described.

  When connecting the connector 20, as shown in FIGS. 2A and 2B, the plug 21 of the connector 20 mounted on the surface of the control main board 40 and exposed to the front side of the board case 10 has a rectangular frame shape. The fixed base 50 is externally fitted. Next, the jack 22 connected to the tip of the harness 30 is inserted into the plug 21. The inserted jack 22 is fixed to the plug 21 in a non-detachable manner by the fixing claws 23 and 23 on both sides. Specifically, the fixed claws 23, 23 on both sides rotate from the pre-expanded release state to the tapered lock state, and the claw portions 24, 24 on the distal end side engage with the plug 21. Along with this, the operation units 25 and 25 on the front side spread outward. The fixing base 50 is prevented from being detached from the plug 20 and fixed by the protruding portion of the harness 30 of the jack 22 fixed to the plug 21 and the operation portions 25 and 25 on both sides.

  When the insertion of the jack 22 into the plug 21 and the fixing base 50 are fixed, as shown in FIGS. 2 (c) and 2 (d), a square cap-shaped protective lid 60 is pushed into and fixed to the fixed fixing base 50. . The rear portion of the protective lid 60 is inserted between the main body 51 and the protective portion 52 of the fixing base 50, and the four protrusions 53 of the fixing base 50 are fitted into the four openings 61 of the protective lid 60, thereby protecting the protective lid 60. The lid 60 is fixed to the fixing base 50 so as not to be detached. Since the stoppers 64, 64 exist inside the operation portions 25, 25 of the fixing claws 23, 23 of the jack 20, there is no danger that the fixing claws 23, 23 move in the releasing direction. In particular, even if a fraudulent act such as making a hole in the side surface of the protective lid 60 and removing the jack 22 (pressing the operation portion 25 of the fixing claw 23 inward) is attempted, the fixing claw 23 does not rotate. Can prevent illegal acts.

  The harness 30 is pulled out from the plug 22 through the space between the fixing base 50 and the protective lid 60. The protective lid 60 fixed to the fixed base 50 is not detached from the fixed base 50 unless it is destroyed. If the protective cover 60 is destroyed and an illegal act is performed on the internal connector 20, even if the protective cover 60 is remounted, a trace of destruction remains clearly on the protective cover 60. I understand. Since both the fixing base 50 and the protective lid 60 are made of transparent resin and the inside can be visually confirmed, the state of the internal connector 20 can be monitored from the outside. As described above, the fixed base 50 and the protective lid 60 can be turned upside down.

  When the control main board 40 in the substrate case 10 is defective or fails, the control main board 40 must be replaced. At that time, it is necessary to intentionally pull out the jack 22 from the plug 21 of the connector 20. In this case, as shown in FIG. 3A, the linear bulging portion 63 provided in the central portion (upper surface, front surface, lower surface) of the protective lid 60 is cut out with a tool such as a nipper. As a result, the protective lid 60 is divided into left and right parts. If it is divided into left and right parts, as shown in FIGS. 3B and 3C, a tool such as a screwdriver is inserted into the divided part, and the protective lid 60 is opened by half to separate it from the fixed base 50. As described above, the protective lid 60 is relatively easily broken by the excision of the bulging portion 63 and can be removed from the fixed base 50.

  When the protective lid 60 is removed, the jack 22 of the connector 20 can be pulled out from the plug 21 by a normal operation. That is, the fixing claws 23 and 23 on both sides are operated from the locked state to the released state, and the jack 22 is pulled out to the front. If the protective lid 60 is removed, there is no blockage by the stoppers 64, 64, so that the fixing claws 23, 23 are operated smoothly. Thereby, it can isolate | separate, without damaging the connector 20 which is a commercial item. After the control main board 40 is replaced, the jack 22 is inserted into the plug 21 again.

  The gaming machine connector equipped with the protector of the present invention does not need to be implemented on all the connectors of the control main board 40, and in the case of a rotary gaming machine, at least internal lottery, drum stop, medal insertion, etc. What is necessary is just to implement to the connector used for transmission / reception of the signal regarding the main body of a symbol fluctuation display game. In other words, it is only necessary to implement the connector that is at risk of fraud, and it is not necessary to implement it to a connector that does not make sense of fraud, such as a connector connected to a sub-board. That's what it means.

  The gaming machine connector provided with the protector of the present invention is also used for the control main board 40 in the above embodiment, but is not limited to this, and is not limited to this. It can also be used for a control board.

Second embodiment (fixing base provided with ears):
6 and 7 are explanatory views of the assembly procedure of the connector for the gaming machine showing another embodiment of the present invention.

  In this embodiment, the protector protects the gaming machine connector 20 (first connector) composed of a jack and a plug, and is mounted on the control board on the fixing base described in the first embodiment. Another difference is that an ear 55 is provided to cover the top of another connector (second connector). Thereby, not only the gaming machine connector 20, but also other countermeasures (existing inside the ear portion 55 in the figure) arranged in the vicinity thereof can be taken simultaneously. However, an ear that covers the top of another connector (second connector) may be provided on a cap-shaped protective cover that is connected and fixed to the fixing base and covers the first connector. Since the lid is destroyed and discarded as described above, it is more economical to provide the ears on the fixed base.

  The gaming machine connector of the present embodiment is used for the main board 40 for control of a pachislot machine as a gaming machine, and the contents described in the first embodiment are only in that the fixing portion 50 is provided with an ear portion 55. Since they are different, redundant description is omitted.

  The main board 40 for control has a plurality of connectors 20 (including the second connector hidden in the figure) on the front surface of the lower edge for electrical connection with an external circuit. Each connector 20 includes a plug 21 mounted on the surface of the main board and a jack 22 inserted into the plug 21.

  The connector 20 which is the first connector is combined with a fixing base 50 fixed to the connector 20 and a protective lid 60 attached to the fixing base 50 in order to prevent illegal acts. The fixed base 50 and the protective lid 60 are made of a transparent resin so that the state of the internal connector 20 can be visually recognized from the outside.

  In particular, in FIG. 6, the fixing base 50 is provided with an ear portion 55 on the right side (upper portion in the figure), mounted on the control main board 40, arranged near the plug 21, and the lead wire 70. The upper part of the other connector (second connector) connected to is covered. In FIG. 7, the fixing base 50 is provided with two ears 55 on both the left and right sides (upper and lower in the figure), and is mounted on the control main board 40 and disposed near the plug 21. The upper part of two other connectors (second connectors) connected to the lead wire 70 is covered.

  6 and 7 show a state in which the insertion of the jack 22 into the plug 21 and the fixing base 50 are fixed, and a square cap-shaped protective lid 60 is pushed into and fixed to the fixed fixing base 50. The rear portion of the protective lid 60 is inserted between the main body 51 and the protective portion 52 of the fixing base 50, and the four protrusions 53 of the fixing base 50 are fitted into the four openings 61 of the protective lid 60, thereby protecting the protective lid 60. The lid 60 is fixed to the fixing base 50 so as not to be detached. Since the stoppers 64, 64 exist inside the operation portions 25, 25 of the fixing claws 23, 23 of the jack 20, there is no danger that the fixing claws 23, 23 move in the releasing direction. In particular, the fixing claw 23 does not rotate even if an illegal act such as making a hole in the side surface of the protective lid 60 and removing the jack 22 (pushing the operating portion 25 of the fixing claw 23 inward) is performed. Such as fraud can be prevented.
