Description

  The present invention relates to a substrate case for storing a control substrate used in a gaming machine such as a pachinko machine or a slot machine, and a method for sealing the substrate case.

  Conventionally, a gaming machine such as a slot machine has a gaming device such as a reel necessary for playing a game, a main control device having a control circuit for controlling the operation of the gaming device, an effect display such as an electric display for performing a game. A sub-control device having a control circuit for controlling the operation, a power supply device for supplying power to the gaming device and the control board, and the like are provided. Among these, the control devices such as the main control device and the sub-control device are provided with hardware such as a ROM (storage element) in which a program for controlling game operations is recorded, and a CPU such as an LSI having a high-speed calculation function, Control is performed by executing software such as a program stored in the ROM by the CPU. For this reason, if an illegal program that can easily acquire game media such as medals is replaced with a ROM in which an illegal program is written, those who know the contents can intentionally acquire a large amount of game media illegally. End up.

  In order to prevent such illegal acts, a box-shaped board case is provided to store a control board on which a control circuit, which is a main part of the control device, is formed, and the control board is placed inside and the closed board case is sealed. ROM with sealing pin or sealing label, etc., but the destruction of the sealing pin by opening a hole in the sealing pin, etc. In some cases, the ROM is replaced without leaving a trace by attaching a sealing pin that is illegally removed from another machine.

  In the substrate case as described above, since an illegal ROM can be mounted without a trace, even if the sealing portion and the sealing pin of the substrate case are hardened with a cured resin as in Patent Document 1, it is difficult to break and can be broken. There is known a gaming machine in which traces remain and an unauthorized opening of a substrate case can be reliably detected.

JP 2010-110565 A

  However, an improper external force is applied to the board case to form a gap between the base member and the cover member constituting the board case, and the ROM of the control board may be illegally accessed from this gap and replaced with an illegal one. There is.

  The present invention solves such a problem, and an object of the present invention is to provide a substrate case that can more reliably prevent an illegal act against a ROM of a control substrate.

  In order to achieve such an object, a substrate case according to the present invention is configured by housing a control board on which a ROM is detachably mounted in a transparent substrate case in which a base member and a cover member are fitted. A rectangular and box-shaped substrate case. Two long sides facing each other of the substrate case are formed of an L-shaped engaging portion engaged in a sliding manner in the longitudinal direction and an adhesive portion bonded with an adhesive. On the upper side of the substrate case, there are provided a sealing pin, an engaging part and an engaging part when sliding in the longitudinal direction. Since the base member and the cover member are engaged with each other on the lower side of the substrate case via an engaging member and are engaged by sliding in the longitudinal direction, an improper external force is applied in the direction perpendicular to the sliding direction. It becomes impossible to open a gap in the case. Further, since the base member and the cover member are bonded and fitted with the sealing pin from the direction orthogonal to the sliding direction, the case cannot be slid in the longitudinal direction after the adhesive is cured. Therefore, since the entire circumference of the four sides of the substrate case is sealed, it is characterized by a structure in which no gap can be formed in the combined portion of the base member and the cover member even if an improper external force is applied.

  In the state in which the case member and the cover member are fitted, the adhesive portion seems to close the lid, and the adhesive cannot be touched from the outside. The adhesive layer cannot be cut with a sharp knife such as a cutter knife, and the cover member cannot be slid in the reverse direction. Further, if the cover member is swung with a flathead screwdriver or the like, the thin portion of the cover member is deformed or broken, leaving a trace. In addition, the adhesive peels off when the external force is such that the thin portion is damaged. As peeling approaches, the adhesive will whiten, leaving a trace. Even if the adhesive is whitened, a gap is not opened in the combined portion of the base member and the cover member at the L-shaped engagement portion. Therefore, the ROM is not replaced with an illegal one.

  The base member and the cover member are locked from the direction orthogonal to the sliding direction of the cover member with a sealing pin in preparation for an unexpected situation such as removal of the adhesive by some method. This is also useful for preventing fraud.

  Thus, the conventional problem is solved so that it is not accessed illegally by using various methods and is not replaced with an illegal ROM.

  According to the present invention, it is possible to more reliably prevent an illegal act on the ROM of the control board.

A medal payout port 13 and a medal tray 14 for receiving paid out medals are provided at the lower part on the front side of the front door 3.

  As shown in FIG. 2, on the inside of the housing 2, there are a medal payout device 15, a reel unit 5 that drives three reels 5a, 5b, and 5c, a power supply device 16, a main control board 17 that controls the progress of the game, A sub-control board 37 and the like are provided for controlling game operations such as light effects such as lamps and sound effects such as sound effects.

  The main control board 17 is a circuit board having various electronic components such as a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory), and the CPU reads a program stored in the ROM. It functions as a main control device that controls the game.

  Electronic components such as CPU, ROM, and RAM are also mounted on the sub-control board 37. Based on the input signal from the main control board 17, the CPU reads the program stored in the ROM to control the game operation. To function as a sub-control device.

  The main control board 17 is provided above the reel unit 5. The main control board 17 includes a sub-control board 37, another board, or a connector for connecting to other parts via a harness.

  The main control board 17 receives signals from operations of the lever 8, the stop switch 9, the bet switch 10, and the like. These signals are transmitted to the main control board 17 via the door relay board 23 provided on the back side of the front door 3. The main control board 17 controls the reel unit 5, the medal payout device 15 and the like while capturing these signals to control the progress of the game.

  In this gaming machine 1, the player can bet a predetermined number of medals, operate the lever 8 to rotate the reels 5a, 5b, and 5c, and sequentially press the stop switch 9 to stop the reels 5a, 5b, and 5c. When the symbols described on the reels 5a, 5b, and 5c are ready, medals are paid out according to the symbols.

  In order to realize this gaming operation, as a control on the gaming machine 1 side, the number of medals betted is displayed in accordance with the player's operation, and the state where the symbols are aligned (hereinafter referred to as “winning state”) In order to determine whether or not, an effective line set on the display unit 6 is set. Then, lottery is performed in response to the detection of the operation input of the lever 8, and the reels 5a, 5b, and 5c are simultaneously rotated.

  Subsequently, the corresponding reels 5a, 5b, 5c are sequentially stopped in response to detection of an operation input of the stop switch 9.

To control.

  Then, based on the position data of the reels 5a, 5b, 5c when stopped, it is determined whether or not a winning state is established on the set active line. 15 is driven to control the payout of medals according to the winning state or added as credits.

  These controls are realized by the CPU on the main control board 17 taking in various signals and generating command signals to the sub-control board 37 and each device based on a program written in the ROM.

  Next, the substrate case 25 that covers the sub-control substrate 37 will be described in detail. As shown in FIGS. 3 to 13, the substrate case 25 is a sub-control in which electronic components such as a ROM 90 and a connector are mounted inside a case constituted by a base member 31, a cover member 32, an engaging member 33, and a sealing pin 34. One end of the harness 38 fitted to the board 37 and the connector 88 of the sub-control board 37 is accommodated, and the base member 31 and the cover member 32 are bonded to necessary portions with an adhesive.

  The substrate case 25 is attached to a mounting plate 36 made of metal and arranged in a substantially rectangular shape when viewed from the front, which is disposed on the left inner wall surface of the wood case. (Refer to FIG. 3) The details of the mounting will be described. The board case 25 has an engaging protrusion 71 extending outwardly on the lower short side of the two short sides of the cover member 32 facing each other. The engaging protrusion 71 is formed and inserted into a slit 96 provided at a corresponding portion of the mounting plate 36. A fixing hole 48 for mounting is provided on the upper short side, and a screw hole 97 of the mounting plate 36 is formed. Fastened with screws.

  The base member 31 and the cover member 32 are both made of a non-conductive resin such as a transparent polycarbonate resin, and the sub control board 37 housed inside and the ROM 90 mounted on the sub control board 37 are visually observed from the outside. It can be confirmed with.

  As shown in FIG. 5, the base member 31 and the cover member 32 are formed in a substantially rectangular shape when viewed from the front. As shown in FIG. An adhesive accommodating portion 47 is formed between the engaging portions 46. The accommodating portion 47 is shaped like a rectangular vessel and has a shape that can store liquid substances. The edge of the accommodating portion 47 is provided with a paragraph 56 as a relief of the adhesive and a ventilation path 57 as a vent for promoting the hardening of the adhesive. Of the two short sides facing each other of the base member 31, the upper side has a fixing hole 48 for the mounting plate 36, a sealing pin locking part hole 49, and the upper side edge part has a locking hole 50. There is a joint slit 51, and the sealing label attaching part 58 is formed so as to cover it. An insertion hole 52 is formed on the lower side of the two short sides facing each other of the base member 31, and a locking hole 53 made of an oval recess is formed on both ends. A rectangular protrusion 59 is formed in the vicinity of the central portion of the base member 31 as viewed from the front.

  The cover member 32 that is a fitting part with the base member 31 is formed in a substantially rectangular shape when viewed from the front. As shown in FIGS. 6 and 7, L-shaped engagement claws 66 are provided on the back surface of the cover member on the two long sides facing each other at both ends of the long side and in the middle portion. An adhesive protrusion 67 that is an adhesive portion is formed between the plurality of recesses 74 and a squeegee portion 73 is formed at one end of the adhesive protrusion 67. A wall surface 83 that covers the side surface of the base member 31 is formed. Of the two short sides facing each other of the cover member 32, the upper side has a sealing pin locking part hole 68, an outwardly extending locking claw 69, an engaging projection part 70, and two facing each other. An engaging projection 71 that extends outward is formed on the lower side of the short side, and a locking projection 72 is formed on both ends. A connector cover portion 77 protrudes so as to cover the connector 88 (see FIG. 4) of the sub-control board 37 in the front view, and a pressing hole 82 is formed at the tip of the protruding shape. A plurality of openings 76 are formed, and connectors and other electronic components provided on the sub-control board 37 are exposed to the outside from the openings 76. The rib 84 extending from the inner periphery of the opening 76 is formed so as to be orthogonal to the sub-control board 37. Similarly, slightly above the center of the inner surface, a projection 78 is formed so as to be orthogonal to the control board 37 so as to surround and cover the ROM 90 of the sub-control board 37.

  As shown in FIG. 7, an engagement member 33 and a sub control board 37 on which a plurality of connectors and other electronic components are mounted are fixed to the inner surface of the cover member 32. The engaging member 33 is made of a non-conductive resin such as a transparent polycarbonate resin, and is formed of a fixing hole and three engaging protrusions 86.

  The sub control board 37 is equipped with a harness 38 that communicates between the ROM 90 and the main control board 17. As shown in FIG. 9, the ROM 90 has a sub-control with a protrusion 78 extending vertically from the inner surface of the cover member 32. The board 37 is abutted so as to surround the ROM 90, and the connector cover 77 is covered with one end of the harness 38 fitted to the connector 88 as shown in FIG. It becomes impossible to remove one end of the harness 38. A plurality of holding holes 82 are opened on the protruding surface of the connector cover 77. When there is poor contact due to insufficient fitting between the harness 38 and the connector 88, a rod having a round shape or the like having a diameter inserted through the holding hole 82. Consideration has been made so that contact failure can be avoided by pressing the fitting portion with a material.

  Similarly, on the cover member 32, a rib 84 extending vertically from the inner periphery of the opening 76 and a protrusion 78 formed near the center abut against the component mounting surface of the sub-control board 37. By abutting, foreign matter insertion from the opening 76 can be prevented, and when the protrusion 78 abuts on the sub-control board 37, double protection is provided. (Refer to FIG. 9 (Da) (Db))

  Further, by providing the protrusion 59 of the base member 31, it is possible to suppress the deflection of the sub-control board 37. Since there is no space for the ROM 90 to be taken out even if foreign matter is inserted, it is mounted on the sub-control board 37. The ROM 90 is not replaced with an illegal one. (See FIG. 9 (Db))

  When the base member 31 and the cover member 32 are fitted and sealed, a predetermined amount of adhesive is applied to a predetermined portion of the accommodating portion 47 of the base member 31, and the base as shown in FIG. The bottom surface of the engaging claw receiving portion 54 of the member 31 and the L-shaped engaging claw 66 of the cover member 32 are butted together.

  When the L-shaped engaging claw 66 of the cover member 32 is abutted against the engaging claw accommodating portion 54 of the base member 31, the adhesive 89 poured into the accommodating portion 47 is pressed by the adhesive protrusion 67 and is accommodated in the accommodating portion 47. Then, the minute space of the protrusion 67 is filled with the adhesive 89 (see FIGS. 9D and 9D).

  At the same time that the cover member 32 is slid in the longitudinal direction, the engaging portion 46 of the base member 31 and the L-shaped engaging claw 66 of the cover member 32 are engaged. When the L-shaped engaging claw 66 is engaged, it cannot be detached in a direction perpendicular to the sliding direction. (See FIG. 8 (Cb))

  The squeegee portion 73 at the end of the adhesive protrusion 67 of the cover member 32 securely adheres to the portion to be bonded without leaking the adhesive in a space unrelated to bonding when sliding in the longitudinal direction. There is also the purpose of inducing the adhesive as possible. The induced adhesive spreads as far as the front of the section 56 as a paragraph which is an edge of the storage section 47. In addition, there are a plurality of recesses 74 at each location of the adhesive protrusion 67, and the adhesive surely sinks into the recess 74 when the cover member 32 slides. Can be bonded more firmly. After the adhesive is cured, it cannot be slid in the opposite direction to that during assembly. Similarly to the cover member 32, the base member 31 has a plurality of recessed portions 55 in the accommodating portion 47, which contributes to increasing the adhesive force in the sliding direction as described above.

  In order to increase the adhesive strength, the depth of the accommodating portion 47 of the base member 31 and the adhesive protrusion 67 of the cover member 32 is increased. Alternatively, by increasing the width of the accommodating portion 47 of the base member 31 and the adhesive protrusion 67 of the cover member 32, the adhesive area is further increased, and the adhesive strength is increased and becomes stronger.

  Note that the adhesive is transparent, is a one-component moisture-curing elastic adhesive that reacts with moisture in the air and cures by notification for a predetermined time, and does not contain a solvent. The base member 31 and the cover member 32 are less likely to generate gas when the adhesive is cured, and can easily be distinguished from whitening caused by peeling of the adhesive when an external force is applied to the substrate case. In the present invention, a one-component moisture-curing elastic adhesive is employed, but an ultraviolet curable resin that is cured by irradiating with ultraviolet rays may be employed. The color may be colorless and transparent, or may be colored and transparent.

  By providing the air passage 57 at the edge of the accommodating portion 47 of the base member 31, air containing moisture can be taken in from the air passage 57. The adhesive driven into the minute space between the accommodating portion 47 of the base member 31 and the adhesive protrusion 67 of the cover member 32 reacts with moisture in the air, and the curing of the adhesive can be promoted.

  When the base member 31 and the cover member 32 are slid in the longitudinal direction, the locking claws 69 are fitted into the locking holes 50 on the upper sides of the base member 31 while being elastically deformed and locked, and are engaged with the engagement slit 51. At the same time as the protruding portion 70 is inserted, the sealing pin locking portion hole 49 and the sealing pin locking portion hole 68 are fitted so as to overlap each other. In addition, the engaging projections 86 of the engaging member 33 attached to the cover member 32 are inserted into and engaged with the insertion holes 52 on the lower side of each other, and at the same time, the locking holes 53 and the locking projections 72 are locked. By doing so, the base member 31 and the cover member 32 are fixed.

  When the base member 31 and the cover member 32 are fixed, a temporarily fixed state that cannot be easily slid in the reverse direction is obtained. When the adhesive is cured in the temporarily fixed state, the base member 31 and the cover member 32 are fixed by the adhesive and cannot be separated.

  In this state, the gap is not opened by an inappropriate external force on each of the four sides of the substrate case 25, and the substrate case 25 cannot be slid and opened by the action of the adhesive.

  The adhesive part is in a state in which the cover is closed by the cover member 32, and the adhesive part is not touched so that the adhesive layer cannot be cut with a sharp blade or the like. For example, if the cover member 32 is deformed or damaged when it is swung with a flat-blade screwdriver from the vicinity of the bonded portion, a trace remains.

  Next, the sealing pin 34 will be described. The sealing pin is a locking pin provided integrally with a pair of locking claws 91 protruding outward and a substantially square head 92 covering the locking claws 91. When the base member 31 and the cover member 32 are slid in the longitudinal direction, the sealing pin locking portion hole 49 and the sealing pin locking portion hole 68 formed on the upper side of each other are fitted so as to overlap each other. Then, the head 92 is pushed down from the direction orthogonal to the sliding direction of the sealing pin 34, and is inserted between the sealing pin locking portion holes 49 and 68 to be locked. The sealing pin 34 is formed of a non-conductive resin such as a transparent polycarbonate resin containing a red pigment so that the presence of the sealing pin 34 is easily visible.

  Locking with the sealing pin 34 is an effective means for preventing the base member 31 from sliding in the direction opposite to the direction of engagement of the cover member 32 in case the adhesive is removed by any method. .

  When the sealing pin 34 is bonded with an adhesive, before the sealing pin 34 is locked, the base member 31 and the cover member 32 are slid and fitted to each other, and the connecting portion recess 79 of the cover member 32 is placed. After applying a certain amount of adhesive, the sealing pin 34 is pushed in and locked, or after the sealing pin 34 is pushed in and locked, it is placed around the head 92 of the sealing pin 34 and on the top surface of the head 92. By pouring and curing a fixed amount of adhesive, it becomes difficult to remove the sealing pin 34, which is a better means against fraud. The adhesive may be a one-component moisture-curing elastic adhesive that cures by notifying for a predetermined time at the above-mentioned transparent room temperature, or an ultraviolet curable resin that cures by irradiating with ultraviolet rays. You may do. The color may be colorless and transparent, or may be colored and transparent.

  Further, the sealing label 35 can be employed in order to prevent an illegal action such as replacement with a ROM. As shown in FIG. 3, the surface of the sealing label 35 is printed such as strictly forbidden to open, and the back surface is coated with an adhesive, and is pasted across the base member 31 and the cover member 32. The base member 31 and the cover member 32 are pasted along two surfaces. The sealing label 35 may be a fragile label that breaks when it is peeled off, or the label that has been peeled off when peeled off, the base member 31 that is the adherend, and the label that remains on the cover member 32, such as already opened. It may be.

  By sealing each part using various methods such as locking, engagement, adhesion, sealing pins and sealing labels to the substrate case 25 as described above, the substrate case 25 is illegally opened, It is possible to prevent the ROM 90 mounted on the sub-control board 37 from being replaced with an illegally tampered one.

  When substrate replacement occurs due to a failure of the sub-control substrate 37 or the like, it is necessary to release the sealing of the substrate case 25, and design considerations are made to make opening as easy as possible.

  In order to release the sealing, as shown in FIG. 11, the broken line portion of the connecting portion accommodating portion 60 with the sealing pin 34 on the upper side of the base member 31 is broken with a cutter such as a nipper or an ultrasonic cutter. By cutting the connecting portion accommodating portion 60, the three parts of the base member 31, the cover member 32, and the sealing pin 34 are destroyed as shown in FIG. 13, and therefore the three parts cannot be reused. .

  Next, when the plurality of V-shaped grooves 80 (see FIG. 6) of the cover member 32 are used as marks, and the broken line portion shown in FIG. 12 is cut with a cutter such as a nipper or an ultrasonic cutter, the base member 31 and the cover member 32 are bonded. The part is cut off, and the sub-control board 37 can be taken out by sliding and separating the base member 31 and the cover member 32 in the opposite direction to that during assembly fitting.

  This sealing release means is intended for maintenance such as substrate replacement, and in the unlikely event that the adhesive part is cut off when disassembled by the above-described sealing release method by fraud, It can be determined that the shape of the substrate case 25 is clearly different from the regular one, and it can be found that an illegal act has been made.
