Description

  The present invention relates to a control board assembly for a gaming machine including a control board configured by mounting a ROM or the like in which control data is stored, and a board case for housing and holding the control board.

  In gaming machines represented by pachinko machines, slot machines, etc., a control board is provided for controlling the operation of the gaming machine. For example, in a pachinko machine, a front frame assembled to be openable and closable with respect to an outer frame. A game board or the like is mounted on the back-side storage frame, and a control board is attached to the game board. Similarly, in the slot machine, a control board is attached to the back side of the front mask or the inside of the cabinet. These control boards are boards that control the operation of pachinko machines or slot machines, such as prize ball or medal payout control, opening / closing control of electric objects, reel rotation control, symbol combination occurrence probability control, etc. ROM in which the control software is stored is mounted and has a role as a central control device for controlling the operation of the gaming machine (see, for example, Patent Document 1).

  A control board having such a role as a central control device is accommodated in a board case composed of a case body member and a case lid member (hereinafter referred to as control) as a countermeasure against fraud such as replacement with a counterfeit ROM. Board board assembly). Even if this countermeasure against illegal acts is taken, for example, an illegal act such as forcibly creating a gap between the case body member and the case lid member and inserting a tool or the like through the gap to replace the counterfeit ROM may be performed. Therefore, for example, Patent Document 2 discloses a configuration in which a frame that surrounds the ROM is provided on the case lid member in order to prevent such fraud, and this tool allows a tool or the like to reach the ROM. Can be prevented.

  The control board is generally configured by soldering electronic components such as a plurality of ROMs to the board body, but a ROM that is not scheduled to be revised later in the data stored in the plurality of ROMs is directly a board. On the other hand, the ROM that is to be soldered to the main body and is scheduled to be revised later with the version upgrade etc. is detachably attached to the socket connector (connection member) soldered to the board main body. Is done. In this way, when the ROM is configured to be mounted on the board body via the socket connector, the gaming machine can be upgraded simply by replacing the revised data with the ROM in which the revised data is stored. Compared to the replacement method, the upgrade can be simplified and the cost can be reduced.

  FIG. 11 illustrates a conventional configuration in which a ROM is mounted on a board body using a socket connector. FIG. 11A illustrates a socket connector 520 soldered to the board body 510 and the socket connector 520. In this manner, the ROM 530 is detachably mounted, and FIG. 12B is a cross-sectional view taken along the line XI-XI in FIG. The socket connector 520 includes a pair of main body portions 521 that hold a plurality of terminal portions 522 and a rod-shaped connection portion 523 that connects the main body portions 521 to each other. When the ROM 530 is attached to the socket connector 520, a connection member side space 524 is formed between the ROM 530 and the substrate body 510. In FIG. 11A, the ROM 530 is virtually indicated by a two-dot chain line in order to easily illustrate the shape of the socket connector 520.

  By the way, in recent years, a socket connector, particularly a socket connector in which the connecting member side space 524 is formed when the ROM 530 is mounted as described above, is used to perform unauthorized operation control in the connecting member side space 524. There is a problem of illegal acts such as storing an illegal ROM 540 in which the data is stored and electrically connecting the illegal ROM 540 to the ROM 530 or the board body 510 to illegally pay out game balls. As described above, when the unauthorized ROM 540 is accommodated in the connecting member side space 524, the unauthorized ROM 540 is surrounded by the board body 510, the socket connector 520, and the ROM 530. It ’s hard. In order to accurately check the presence or absence of the illegal ROM 540, for example, it is necessary to open the case cover member with respect to the case body member and remove the ROM 530 from the socket connector 520 for confirmation. The man-hour will increase remarkably. As described above, there is a problem that it is difficult to prevent the unauthorized ROM from being mounted and to easily check the state in the connection member side space.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a control board assembly for a gaming machine that can prevent the unauthorized ROM from being mounted and can easily check the state in the connection member side space. And

  In order to achieve such an object, the control board assembly of the gaming machine according to the present invention is mounted with required electronic components (for example, the fixed ROM 52a, the left connection connector 53, the right connection connector 54, and the removable ROM 110 in the embodiment). A control board having a flat shape (for example, the main control board 51 in the embodiment) and a case member (for example, the board case 55 in the embodiment) for accommodating and holding the control board, and operated by the control board. A control board assembly (for example, main control board assembly 50 in the embodiment) of a gaming machine (for example, pachinko machine PM in the embodiment) to be controlled, the control board includes the electronic component, the control board, and A connection member (for example, the socket connector 120 in the embodiment) for electrically connecting the two is mounted. A connection member side space between the connection member, the electronic component, and the control board, the control board facing a connection member side space of the connection member mounted on the control board A protrusion insertion hole is formed in the housing member, and the case member includes an accommodation restriction protrusion that is inserted into the protrusion insertion hole of the control board and protrudes into the connection member side space.

  According to the control board assembly of the gaming machine according to the present invention, the projection insertion hole is formed in a portion of the control board facing the connection member side space, and the case member is inserted through the projection insertion hole to be in the connection member side space. It is configured with an accommodation regulating projection that protrudes. With this configuration, when the control board is accommodated in the case member, the accommodation restricting protrusion can be inserted into the protrusion insertion hole and protruded into the connection member side space. Therefore, if an attempt is made to house the control board in the case member in a state where the unauthorized ROM is housed in the connection member side space, the unauthorized ROM and the housing restricting projection interfere with each other so that the control board can be housed and held in the case member. Therefore, it is possible to prevent an illegal act performed by accommodating the illegal ROM in the connection member side space. In addition, since the inside of the connection member side space can be visually confirmed through the protrusion insertion hole formed in the control board, it is possible to easily confirm the presence or absence of the illegal ROM.

  The case member is formed using a transparent or semi-transparent material, and the control board assembly is a swing mechanism that swingably supports the case member with respect to a main body rear surface portion of the gaming machine. (For example, the hinge mechanism 38 in the embodiment) is mounted with the surface of the control board opposite to the surface on which the connection member is mounted facing the back surface of the main body, and the swing mechanism Accordingly, it is preferable that the control board assembly can be swung from the opposite surface to a position where the inside of the connecting member side space can be visually recognized through the protrusion insertion hole.

  According to this aspect, the control board assembly can be swung to a position where the inside of the connection member side space can be visually recognized through the protrusion insertion hole from the surface of the control board opposite to the surface on which the connection member is mounted. Preferably it has become. When configured in this way, the inside of the connection member side space can be visually confirmed by simply changing the direction using the hinge mechanism without removing the control board assembly mounted on the gaming machine, and whether or not there is an illegal ROM It becomes possible to confirm more easily.

  Further, it is preferable that a fluorescent material emitting fluorescence is provided on at least one of a surface of the electronic component facing the connection member side space and a surface of the control board facing the connection member side space.

  According to this aspect, it is preferable that the phosphor is provided on at least one of the surface of the electronic component that faces the connection member side space and the surface of the control board that faces the connection member side space. In the case of this configuration, for example, when the illegal ROM is not accommodated in the connection member side space, the fluorescence is visually recognized through the projection insertion hole formed in the control board. On the other hand, when the illegal ROM is accommodated, the fluorescence is visible through the projection insertion hole. The fluorescence is not visible. Therefore, it is possible to easily check for the presence or absence of illegal ROM simply by determining whether or not fluorescence is visually recognized through the protrusion insertion hole.

  According to the control board assembly of the gaming machine according to the present invention, it is possible to prevent an illegal act performed by accommodating the illegal ROM in the connection member side space.

The game handle is stored in the ball tray 6 and the operation handle 8 is stored. A game is started by rotating the game. When the operation handle 8 is turned, the game balls stored in the ball tray 6 are shot one by one into the game area PA of the game board 10 by the hitting ball launcher, and the pachinko game is developed thereafter.

  In the pachinko machine PM configured as described above, the present invention is applied to the main control board assembly 50. The overall configuration of the main control board assembly 50 will be described below with reference to FIGS. To do.

  The main control board assembly 50 includes a main control board 51 that comprehensively controls the operation of the pachinko machine PM, and a board case 55 as a case member that accommodates and holds the main control board 51 inside. The substrate case 55 includes a case main body member 60 attached in a state of being opposed to the back side portion of the back set board 30, and a case lid member 70 attached to the case main body member 60 so as to be opened and closed. The main control board assembly 50 is configured such that the case lid member 70 is attached to the case body member 60 so as to be openable and closable in a state where the main control board 51 is attached to the inner surface of the case lid member 70.

  As shown in FIG. 5, the main control board 51 is electrically connected to a surface of a rectangular flat plate-like board body 51a by directly soldering a plurality of fixed ROMs 52a storing various control data, and arranged on the left side. .. And electronic components such as left connection connectors 53, 53,... Soldered to the substrate body 51a and right connection connectors 54, 54,. In addition, for example, when the pachinko machine PM is upgraded, the removable ROM 110 that requires rewriting of stored data is connected to a socket connector 120 (connecting member) as a connecting member soldered to the board body 51a. It is detachably attached. Thus, it is possible to easily upgrade the version by simply replacing the removable ROM 110 with new data stored without replacing the entire main control board 51. In addition, board attachment holes 51b, 51b,... Are formed at the four corners of the board body 51a.

  The case body member 60 has a rectangular box shape with an opening on the rear surface side, and is integrally molded by a molding means such as injection molding using a transparent or translucent resin material such as ABS resin or polycarbonate (PC). Is done. Reinforcing ribs 61 are formed vertically and horizontally on the inner bottom of the case body member 60, and the strength of the case body member 60 is improved by the reinforcing ribs 61.

  Hinge shafts 62 and 62 are formed at the left end portion of the case body member 60 so as to be hingedly engaged with the hinge arm 74 of the case lid member 70. Locking arms 63 and 63 projecting rearward are formed on the outer surfaces of the upper and lower side walls of the case body member 60, and are respectively locked to locking protrusions 75 formed on the side surfaces of the case lid member 70. Yes. For this reason, the case lid member 70 is engaged with the case main body member 60, and the hinge arm 74 is hingedly engaged with the hinge shaft 62 so that the closed state shown in FIG. 3 and the opened state shown in FIG. As shown in FIG. 3, the locking arm 63 is locked to the locking projection 75 and temporarily held in the closed state as shown in FIG.

  An inner guard rib 64 protrudes from the inner side of the edge of the case body member 60, and when the case lid member 70 is attached to the case body member 60, the outer guard rib (not shown in the figure). ) Is located inside. An edge contact portion 65 is formed on the outer side of the edge of the case main body member 60 so as to be connected to the inner guard rib 64, and when the case cover member 70 is attached to the case main body member 60, The outer guard rib comes into contact with the edge contact portion 65.

  The case lid member 70 has a rectangular box shape covering the opening of the case body member 60, and is integrally formed by molding means such as injection molding using a transparent or translucent resin material such as ABS resin or polycarbonate (PC). To be molded. Boss-shaped board mounting portions are formed at the four corners on the front side (inner surface side) of the case lid member 70 with screw holes (both not appearing in the figure), and the main control board 51 is provided with the board mounting holes 51b. It is fixed to the inner surface side of the case lid member 70 by being fixed by a board mounting screw 59 via the.

  A left connector opening 72 is formed on the left side of the case lid member 70. As shown in FIG. 3, the left side connection of the main control board 51 with the case lid member 70 attached to the case body member 60 is provided. .. Are configured to be exposed to the outside through the left connector opening 72. .. Are formed on the right side of the case lid member 70. With the case lid member 70 attached to the case body member 60, the right connection connectors 54, 54 of the main control board 51 are formed. 54 are exposed to the outside through the right connector opening 73.

  Thus, when the case lid member 70 is attached to the case body member 60 in a closed state that covers the opening of the case body member 60, the locking arm 63 is only locked to the locking projection 75. The case lid member 70 can be easily opened with respect to the case body member 60. Therefore, the main control board assembly 50 is provided with an unauthorized opening prevention mechanism 90 in order to prevent the case cover member 70 in the closed state from being opened and to prevent unauthorized operation.

  The fraud prevention mechanism 90 has a conventionally known configuration, and various configurations are used. In the present embodiment, as shown in FIGS. 3 to 5, a main body side engaging portion 91 integrally connected to the case main body member 60 and a lid side engaging portion connected to the case lid member 70 via a connecting portion 94. The structure which consists of 93 and the coupling member 95 for couple | bonding both the engaging parts 91 and 93 is illustrated. The coupling member 95 is inserted into the engagement recess 91a of the main body side engagement portion 91, and the engagement protrusion 95a formed on the side surface and the engagement portion in the engagement recess 91a are engaged with each other so as not to be detached. (See FIG. 4). When the case lid member 70 is closed in this state as shown in FIG. 3, a portion protruding above the coupling member 95 is an engagement recess 93 a of the lid side engagement portion 93 (not shown in the figure, but the lid side engagement The engagement protrusion 95b formed on the side surface and the engagement portion in the engagement recess 93a are detachably engaged with each other with respect to the case main body member 60. The case lid member 70 is held in a closed state as shown in FIG. In addition, in order to open the case lid member 70 from this closed state, the connecting portion 94 of the lid side engaging portion 93 is cut.

  In the main control board assembly 50, a case sealing portion 99 is provided adjacent to the unauthorized opening prevention mechanism 90. The case sealing portion 99 includes a main body side sealing portion 96 integrally connected to the case main body member 60, a lid side sealing portion 97 integrally connected to the case lid member 70, and a sealing member (not shown) accommodated therein. Z)). Both sealing portions 96 and 97 are in contact with each other with the case lid member 70 closed against the case main body member 60, and the sealing member holds the closed state of the cases 60 and 70 inside thereof. Can be attached together. It should be noted that a sealing seal is pasted (not shown) across the outer surfaces of the sealing portions 96 and 97 in a state where the case lid member 70 is closed with respect to the case body member 60. Therefore, by opening the case lid member 70 with respect to the case main body member 60, the seal seal and the seal member are surely destroyed, and it remains as evidence that the destruction trace is opened.

  As can be seen from the above description, when the case lid member 70 is closed with respect to the case body member 60 as shown in FIG. 3, the case body member 60 and the case lid member 70 are engaged by the unauthorized opening prevention mechanism 90. The sealing member is held inside while being engaged with the main body side sealing portion 96 and the lid side sealing portion 97. Therefore, for example, when the case lid member 70 is opened to perform an illegal act, it is necessary to first disconnect the connecting portion 94 that connects the case lid member 70 and the lid side engaging portion 93. As a result, the connection between the case main body member 60 and the case lid member 70 by the unauthorized opening prevention mechanism 90 is cut off, but the main body side sealing portion 96 and the lid side sealing portion 97 are still sealed at the case sealing portion 99 by the sealing seal and the sealing member. Are in a connected state, the case lid member 70 cannot be opened unless the connection of this portion is released. Therefore, the case lid member 70 can be opened by swinging the case lid member 70 with respect to the case main body member 60, but on the other hand, a destructive trace is surely formed on the seal seal and the seal member. As described above, in the main control board assembly 50, when the case lid member 70 is opened, a destruction trace is formed in the connecting portion 94, the sealing seal, and the sealing member. It is possible to easily grasp the presence / absence of openness (presence of fraud).

  However, recently, there are cases where fraudulent acts are performed on the main control board 51 without leaving any destruction traces on the unauthorized opening prevention mechanism 90 and the sealing member. As an example of this illegal act, an illegal ROM (not shown) in which control data for illegally operating the pachinko machine PM is stored inside the socket connector 120 is accommodated, and the board body 51a and the removable ROM 110 are electrically connected. There is something that is done by connecting to. In the conventional configuration, since the illegal ROM is accommodated by the removable ROM, the socket connector, and the board body, whether or not the illegal ROM is accommodated inside the socket connector is determined based on whether or not the illegal ROM is accommodated inside the socket control board. It was difficult to confirm visually.

  Therefore, conventionally, in order to check whether or not the illegal ROM is accommodated in the socket connector, for example, the case lid member is once opened with respect to the case body member, and then the removable ROM is removed from the socket connector. was there. When confirming in this way, the connecting portion 94 and the sealing member are destroyed each time, so a new sealing member or the like is required every time confirmation is performed, in terms of work man-hours and costs. The burden has increased significantly.

  In contrast to the conventional configuration as described above, the main control board assembly 50 to which the present invention is applied has a configuration in which the illegal ROM cannot be accommodated in the socket connector 120. Even if the illegal ROM is accommodated, the socket connector Since the inside of 120 can be easily confirmed visually, it is characterized in that an illegal ROM can be found easily and immediately. This characteristic configuration will be described in detail below with reference to FIGS.

  6 shows a state in which the detachable ROM 110 is removed from the socket connector 120 in order to easily illustrate the shapes of the socket connector 120 and the board body 51a. FIG. 7 shows a cross-sectional view of the main control board assembly 50 in a state where the case lid member 70 is closed with respect to the case main body member 60.

  As shown in FIGS. 6 and 7, the socket connector 120 includes a pair of upper and lower socket body parts 121, 121 that hold the terminal parts 122, 122 made of a conductive metal material facing each other, and the socket body part. It is comprised from the rod-shaped connection part 123,123, ... which connects 121 partly, and is formed in a substantially rectangular parallelepiped as a whole. The socket connector 120 is provided with a lead portion 129 (see FIG. 9) that is electrically connected to the terminal portion 122 and protrudes toward the board body 51a. When the socket connector 120 is placed at a predetermined position of the board body 51c, the lead portion 129 protrudes on the back side of the board body 51a (the side opposite to the face on which the socket connector 120 is placed). The protruding lead portion 129 is soldered and electrically connected to the board body 51a (details will be described later). Further, the socket main body 121 and the connecting portion 123 are formed using a resin material having insulation properties.

  As shown in FIGS. 6 and 7, ROM mounting protrusions 121 a extending from side to side are provided on the upper surface of each socket main body 121. An attachment portion 125 for positioning and attaching the detachable ROM 110 to the socket connector 120 is formed by the side surface of the ROM attachment protrusion 121a and the upper surface of the socket body 121. When the detachable ROM 110 is attached to the attachment portion 125, a connection member side space 124 surrounded by the bottom surface of the detachable ROM 110, the surface of the substrate body 51a, and the socket connector 120 (connection portion 123) is formed. In addition, a plurality of circular protrusion insertion holes 51c are formed in a portion of the board body 51a facing each connection member side space 124 in a state where the socket connector 120 is soldered to a predetermined position of the board body 51a. FIG. 6 shows an example in which four protrusion insertion holes 51 c are formed in each connection member side space 124.

  On the inner surface of the case body member 60, a plurality of bar-shaped accommodation restriction projections 66 are formed so as to be integrally formed with the case body member 60 using the same transparent resin material as the case body member 60. The diameter of the accommodation restricting protrusion 66 is formed to be substantially the same as or slightly smaller than the diameter of the protrusion insertion hole 51c. Each housing restricting protrusion 66 is formed on the case body member 60 so as to be inserted into the corresponding protrusion insertion hole 51c and protrude into the connecting member side space 124 when the case lid member 70 is closed. Further, the front end portion of the accommodation regulating projection 66 is close to the back surface of the removable ROM 110 when the case lid member 70 is closed, and the accommodation regulating projection 66 has a height of, for example, several mm to several cm. Is formed. When the case lid member 70 is swingably opened and closed with respect to the case body member 60, the projection insertion hole 51 c of the substrate body 51 a fixed to the case lid member 70 is smoothly caught without being caught by the accommodation restriction projection 66. Can be swung.

  The assembly procedure of the main control board assembly 50 to which the present invention configured as described above is applied will be described focusing on the socket connector 120 related to the present invention. First, the removable ROM 110 is mounted on the mounting portion 125 of the socket connector 120 soldered to the board body 51a. By mounting in this manner, the terminal portion (not shown) of the removable ROM 110 is brought into contact with and electrically connected to the terminal portion 122 of the socket connector 120. The board main body 51 a (main control board 51) on which the detachable ROM 110 is mounted is screwed to the case lid member 70 using board mounting screws 59. Then, the case cover member 70 to which the main control board 51 is attached is swung with respect to the case body member 60 and closed, whereby the main control board 51 is accommodated and held inside the case body member 60 and the case cover member 70. Thus, the assembly of the main control board assembly 50 is completed.

  The assembly procedure of the main control board assembly 50 has been described above. By assembling the main control board assembly 50 in this way, as shown in FIG. 7, the housing restricting protrusions 66 are positioned so as to protrude from the connecting member side spaces 124 of the socket connector 120. The leading end is close to the back surface of the removable ROM 110. Therefore, for example, even if the case lid member 70 is once opened with respect to the case body member 60 and the detachable ROM 110 is removed from the socket connector 120 and the illegal ROM is accommodated in the connection member side space 124, In a state where the illegal ROM is accommodated in the connection member side space 124, when the case lid member 70 is closed with respect to the case main body member 60, the illegal ROM and the accommodation regulating projection 66 interfere with each other to cause the case lid member 70 to move. It cannot be completely closed. As described above, the main control board assembly 50 has a simple configuration in which the accommodation restricting protrusion 66 and the protrusion insertion hole 51c are provided, but the illegal action performed by accommodating the illegal ROM or the like in the connection member side space 124 is performed. It can be effectively prevented.

  As described above, in the main control board assembly 50, since the accommodation restricting projection 66 is located so as to protrude in the connection member side space 124, an illegal act of accommodating an illegal ROM or the like in the connection member side space 124 is prevented. However, even if the illegal ROM is accommodated in the connection member side space 124 by any method, the illegal ROM can be easily found. The configuration will be described below with reference to FIG.

  As shown in FIG. 8A, the main control board assembly 50 is attached to the back portion of the back set board 30 so as to be swingable up and down by a hinge mechanism 38. The hinge mechanism 38 is attached to the lower end portion of the main control board assembly 50. On the other hand, the main control board assembly 50 is engaged with the rear portion of the back set board 30 at the upper end portion of the main control board assembly 50. A locking member 39 is attached to hold the back set board 30 so as to face and face the back surface portion. Some pachinko machines are configured with the main control board assembly attached to the front frame or game board without having a back set board. In such a pachinko machine, the hinge mechanism 38 is used to swing the main control board assembly with respect to the front frame or the game board.

  In the state shown in FIG. 8A, when confirming whether or not an illegal act has been performed on the main control board assembly 50, in particular, whether an illegal ROM or the like is accommodated in the connection member side space 124. The engagement of the locking member 39 is released, and the main control board assembly 50 can be seen from the back side of the main control board 51 (the side opposite to the side to which the socket connector 120 is attached) centered on the hinge mechanism 38 (for example, And so that the main control board 51 is positioned substantially horizontally). By doing so, it becomes possible to visually observe the back surface of the main control board 51, and by observing the inside of the connection member side space 124 through the protrusion insertion hole 51c, illegal ROM or the like is not accommodated in the connection member side space 124. Can be easily confirmed visually.

  As described above, since the inside of the connection member side space 124 can be confirmed simply by changing the direction of the main control board assembly 50 using the hinge mechanism 38, the number of work steps and costs required for the confirmation work compared to the conventional configuration can be reduced. The burden on the surface is greatly reduced. In this confirmation operation, the accommodation restriction projection 66 is inserted into the projection insertion hole 51c. However, since the accommodation restriction projection 66 itself is formed of a transparent material, the accommodation restriction projection 66 is inserted into the projection insertion hole 51c. The state in the connection member side space 124 can be visually confirmed while being inserted.

  In the foregoing, the configuration that can easily find the illegal ROM has been described. As described above, the main control board 51 (board body 51a) constituting the main control board assembly 50 is formed with a plurality of protrusion insertion holes 51c for inserting the accommodation restriction protrusions 66. As described above, when the lower surface side of the substrate body 51a in which the protrusion insertion hole 51c is formed is immersed in a solder bath and soldered, molten solder, vaporized flux, or the like passes through the protrusion insertion hole 51c and the substrate body 51a. It is assumed that the surface side is reached. When solder or flux reaches the surface side of the substrate body 51a, it adheres to the socket connector 120, the fixed ROM 52a, the detachable ROM 100, etc., and there is a possibility that problems such as a short circuit may occur. Therefore, it is necessary to mount a member that closes the protrusion insertion hole 51c to the board body 51a and perform soldering.

  In addition, when the relatively large socket connector 120 is placed on the board body 51a, the lead portion 129 of the socket connector 120 may partially float with respect to the board body 51a. If soldering is performed in this state, the electrical connection between the socket connector 120 and the board body 51a becomes incomplete, which may cause a problem. Therefore, it is necessary to perform soldering by placing a member as a weight for pressing the socket connector uniformly against the board body on the socket connector. As described above, when the relatively large socket connector 120 is soldered to the board body 51a in which the protrusion insertion hole 51c is formed, it is necessary to prepare a member for closing the protrusion insertion hole 51c and a member as a weight. .

  Thus, in contrast to the method of preparing each of the member that closes the protrusion insertion hole 51c and the member as a weight, the board body 51a that constitutes the main control board assembly 50 according to the present invention has a structure as shown in FIG. Soldering is performed using the soldering jig 210 having the functions of the two members. The soldering jig 210 includes a weight portion 211 formed in a flat plate shape, and a sealing protrusion 212 that protrudes downward from the weight portion 211 and has a tip portion that can be inserted into the protrusion insertion hole 51c. Consists of

  When soldering is performed by placing a ROM, a connector, or the like on the board body 51a, the projection insertion hole 51c is formed by the sealing projection 212 by placing the soldering jig 210 on the socket connector 120. And the socket connector 120 is uniformly pressed against the board body 51a. For this reason, it is possible to prevent solder and flux from reaching the upper surface side from the solder bath 200 through the protrusion insertion hole 51c, and it is possible to reliably connect the socket connector 120 to the board body 51a. As described above, since the method using the soldering jig 210 can cope with the method of preparing each of the member that closes the protrusion insertion hole 51c and the member as a weight, only one member can cope with it. The burden can be greatly reduced.

  The socket connector 120 in the above-described embodiment is often formed by using, for example, a black resin material having an insulating property, but using a transparent resin material having an insulating property instead of the black resin material. A formed configuration may be used. With this configuration, the state of the connection member side space 124 inside the socket connector 120 can be visually confirmed from the outside. Therefore, if an unauthorized ROM is accommodated in the connection member side space 124, The ROM can be easily found. Further, in this configuration, a convex lens-shaped convex portion 230 can be formed on the side surface portion of the socket connector 120 (the side surface portion of the socket main body 121 and the connecting portion 123) (see FIG. 10). In this way, the inside of the connection member side space 124 can be enlarged and viewed from the side of the socket connector 120. If the inside of the connection member side space 124 can be visually recognized from the outside, a translucent material can be used instead of the transparent resin material.

  In the above-described embodiment, the case body member 260 shown in FIG. 10 can be used instead of the case body member 60. The case main body member 260 is configured by forming a convex lens-shaped convex portion 267 at a portion corresponding to a position where the accommodation restricting protrusion 66 is formed (an outer surface portion of the case main body member 260). When this case main body member 260 is used, the inside of the connection member side space 124 can be enlarged and visually recognized by the convex portion 267 and the accommodation restriction projection 66, and the state in the connection member side space 124 becomes easy to see. Thus, it is possible to accurately check the presence or absence of the illegal ROM.

  In the above-described embodiment, a fluorescent paint that emits fluorescence is applied to at least one of the rear surface of the removable ROM 110 (the surface facing the connection member side space 124) and the surface of the substrate body 51a facing the connection member side space 124. It is also possible to have a configuration. According to this configuration, when the connection member side space 124 is viewed through the protrusion insertion hole 51c, if the connection member side space 124 is bright due to the fluorescence of the fluorescent paint, it can be determined that no illegal ROM is stored. If the fluorescence is not confirmed and it is dark, it can be easily determined that an illegal ROM or the like is housed. Thus, by applying the fluorescent paint that emits light by itself, it is possible to accurately check the presence or absence of illegal ROM even in a dark working environment. In addition, it can replace with the structure which apply | coats a fluorescent paint, and the structure which sticks the fluorescent film which emits fluorescence is also possible.

  Furthermore, instead of the fluorescent paint, it is also possible to use a material that changes the visible color according to the angle of light application. In this configuration, for example, when light from a light source such as an LED is irradiated from the back surface of the substrate body 51a, and the color in the connection member side space 124 seen through the protrusion insertion hole 51c changes according to the direction of the light source. It can be determined that the illegal ROM is not accommodated. On the other hand, if the connection member side space 124 looks dark or the color does not change according to the direction of the light source, it can be easily determined that the illegal ROM or the like is accommodated. Even in this configuration, the presence or absence of the illegal ROM can be easily and immediately confirmed without opening the substrate case 55 (the case main body member 60 and the case lid member 70) without being opened.

  In the above-described embodiment, as illustrated in FIG. 8A, a configuration in which the hinge mechanism 38 is attached to the lower end portion of the main control board assembly 50 so that the back surface of the board body 51 a can be easily seen will be described as an example. However, the mounting position of the hinge mechanism 38 with respect to the main control board assembly 50 is not limited to this. For example, the upper end of the main control board assembly 50 may be used, or a hinge mechanism 38 is attached to the right end of the main control board assembly 50 as shown in FIG. A configuration in which the main control board assembly 50 can be opened / closed to the left / right with respect to the game board 10) may be adopted. A configuration in which a hinge mechanism 38 is attached to the left end portion of the main control board assembly 50 is also possible. That is, the main control board assembly 50 can be swung with respect to the back set board 30 and may be swung to a position where the back surface of the board body 51a can be visually recognized as needed. Instead of the hinge mechanism 38, for example, a hinge having a simpler configuration may be used.

  In the above-described embodiment, the example in which the present invention is applied to the socket connector 120 portion for detachably attaching the detachable ROM 110 to the board body 51a has been described. However, other than this, for example, a CPU (Central Processing Unit), The present invention can also be applied to a socket connector in which an IC (integrated circuit) or the like is detachably attached to a substrate body.

  In the above-described embodiment, the main control board 51 has been described by exemplifying a configuration in which the main control board 51 is fixed to the inside of the case lid member 70 by the board mounting screws 59, but the present invention is applied to this configuration only. Is not to be done. For example, the present invention can be applied to a configuration in which the main control board 51 is fixed to the inside of the case main body member 60 by the board mounting screws 59. In the case of this configuration, the main control board 51 is accommodated inside the case body member 60 so that the projection insertion hole 51c of the board body 51a is inserted into the accommodation restriction projection 66 of the case body member 60. The main control board 51 is fixed to the case body member 60 with screws. Here, if an unauthorized ROM is accommodated in the connection member side space 124, the unauthorized control ROM and the accommodation restricting projection 66 interfere with each other so that the main control board 51 cannot be fixed to the case body member 60. In addition, it is possible to prevent an illegal act performed by accommodating an illegal ROM in the connection member side space 124. In the configuration in which the main control board 51 is fixed to the case main body member 60, in addition to the effect of preventing the illegal ROM from being housed in the connection member side space 124 by the above-described housing restriction protrusion 66, the housing restriction protrusion 66 The case body member 60 and the main control board 51 can be positioned.

  In the above-described embodiment, the example in which the present invention is applied to the main control board assembly 50 has been described. However, the present invention is not construed as being limited thereto. For example, the present invention can also be applied to a payout control board assembly 45 that mainly controls payout control of game balls.

  In the above-described embodiment, an example in which the present invention is applied to the main control board assembly 50 configured to swing and open by the case lid member 70 being hingedly engaged with the case main body member 60 has been described. The present invention is not limited to the substrate assembly having this configuration. For example, the present invention may be applied to a substrate assembly configured to slide and move the case lid member with respect to the case body member while the case body member covers the case lid member, and engage and hold both in the closed state. Is possible. When the present invention is applied to the substrate assembly having this structure, the main control board is not fixed to the case lid member, but the main body substrate protrusion insertion hole is inserted into the housing body member housing restriction protrusion. The control board is fixed to the case main body member, and in this state, the case lid member is slid relative to the case main body member to engage and hold the two. As described above, the present invention can be applied to all board cases in which the case main body and the case lid member are engaged to accommodate and hold the main control board.

  In the above-described embodiment, the case where the present invention is applied to the main control board assembly 50 including one fraud prevention mechanism 90 and one case sealing portion 99 has been described as an example. The present invention can be applied to various substrate assemblies regardless of the configuration of the (case sealing portion).

However, the gaming machine to which the present invention is applied is not limited to this, and a gaming machine other than the pachinko machine, For example, it can be applied to a slot machine.

  In the above-mentioned embodiment, although the structure which formed the accommodation control protrusion 66 integrally in the case main body member 60 was illustrated and demonstrated, this invention is not limited to this structure. For example, a configuration is possible in which the housing regulation protrusion 66 is formed as a separate part from the case body member 60 and the housing regulation protrusion 66 is fixed to the case body member 60 using a fastening member such as a screw.
