Examples of the control board include a main control board on which electronic components such as a CPU, a ROM, and a RAM are mounted, a display control board, a light emission control board, a power supply board, a game ball payout control board, and the like. Each of the control boards described above is controlled so that an appropriate gaming state is maintained by transmitting or receiving electrical signals between the control boards according to the gaming state. Therefore, each control board is electrically connected by the connection member which consists of a wiring member (code | cord) and the connector member attached to the terminal part.

  By the way, in the above gaming machine, with the increase in the number of electrical components and control boards than before, the number of wiring bodies required for connection also increases, and the connection may be complicated. Therefore, for example, a gaming machine has been proposed that uses a connector member different from other electric parts for a specific control board or electric part (see Patent Document 1).

  Moreover, in the said control board, in order to coat | cover the said control board, what is provided with the cover body is common. The control board and the terminal portion (connector member) of the connection member are connected via an opening provided in the cover body. In the case of such a structure, there is a possibility that a foreign object is inserted from the opening of the cover body and an illegal act is performed on the internal control board. If a foreign object is inserted, a malfunction may occur in the control by the control board, and a normal game may not be executed.

  A mode of connecting a plurality of control boards will be described with reference to FIG. As the illustrated control board, a main control board 50 and a symbol control board 57 (stored in the board housing case) stored in the control board housing case 60 are illustrated, and these are schematically illustrated. The control boards are electrically connected between the control boards by a connecting member 200 having a connector member 205 at the terminal portion 202 of the wiring member 201 and a wiring member (wiring cord) 201 having an appropriate number. It is possible. By connecting the connection member 200, particularly the connector member 205, to the connection portion 70 (80), the control boards are connected to each other. Thus, signals relating to various games generated by the main control board 50 are transmitted to appropriate control boards, and various games are executed by controlling each electrical component.

  The structure of the control board housing case 60 will be described in more detail with reference to FIG. The control board housing case 60 covers and holds the main control board 50 to protect electronic components (CPU, ROM, RAM, IC, transistor, resistor, capacitor, etc.) on the control board. The main control board 50 is disposed on the case body 61, and a cover body 65 is attached to the case body 61. An appropriate number of connection portions 70 are mounted on the main control board 50, and the connector member 205 of the connection member 200 is inserted through the opening 67 of the cover body 65 and is detachably connected to the connection portion 70. For convenience of explanation, a control board housing case for housing the main control board is illustrated, but other control boards (see FIG. 2) are similarly housed (covered) in each control board housing case.

  Subsequently, the connection unit 70 will be described with reference to FIGS. 5 and 6. The connection unit 70 includes a main body 71 that allows the terminal 202 (connector member 205 shown in FIG. 3 in the embodiment) of the connection member 200 to be detachable, and the main body 71 as a control board (the main control board 50 is exemplified). It comprises a base plate 75 to be attached. The main body 71 has a substantially rectangular parallelepiped shape surrounded by a side wall 73 having a hollow inside. A hollow portion inside the main body becomes an insertion port 72, and the connector member 205 is attached to the insertion port 72. Since the base plate 75 is formed to extend outward from the side wall 73, the base plate 75 covers at least a part of the control board (main control board 50).

  The hatched portion shown in FIG. 5B is the insertion port 72, and the area of the insertion port 72 (that is, the area of the hatched portion) is the area of the opening 67 as can be seen from FIG. It is made smaller. In the figure, reference numeral T denotes a connection terminal, and the connection terminal is inserted into the connector member and engaged therewith. As shown in FIG. 5C, the connection terminal T penetrates the base plate 75. Then, the lower connection terminal of the base plate is soldered to the control board (wiring portion not shown), and the connection portion is fixed to the control board. Reference numeral 76 denotes a contact surface of the base plate.

  In the connection portion 70 shown in FIGS. 5A to 5C, the main body portion 71 and the base plate 75 are integrally formed. That is, the connection part 70 is a resin member and is formed at once. For this reason, it is possible to relatively easily attach the connecting portion and the control board and to reinforce the close contact with the control board.

  The structure in the vicinity of the connecting portion 70 will be described with reference to a schematic cross-sectional view of the main part of the control board housing case 60 shown in FIG. As illustrated, the connection terminal T of the connection portion 70 (the main body portion 71 and the base plate 75) is attached to the control board (the main control board 50 is exemplified) with solder H. The main control board 50 is fixed to the case body 61 with screws (not shown), and a cover body 65 is overlaid so as to cover the main control board 50 from above. The cover body 65 and the case body 61 are fixed by a fixing method (see Japanese Patent No. 3341868, etc.) provided with appropriate fraud prevention means.

  As already shown in FIG. 5, the connecting portion 70 is disposed in the opening 67, and the connector member 205 of the connecting member 200 is attached to the insertion port 72 in the main body 71. In the opening 67, a very small space 67 o is formed between the side wall 73 of the connecting portion 70 and the peripheral edge 66 of the opening 67 in the cover body 65. The size of the space 67o, that is, the distance between the side wall 73 and the peripheral edge 66 is preferably as small as possible. This is because the risk of foreign matter being inserted from the opening 67 can be reduced. According to the embodiment, a fraud prevention part 63 (corresponding to the third protrusion) is provided. When the cover body 65 is covered on the main control board 50 (and the case body 61), the tamper-proof portion 63 is located facing the outer side of the peripheral edge 75e of the base plate.

  In addition, as shown in the schematic top view of FIG. 7, the base plate 75 (contact surface 76) is formed larger than the opening 67. That is, the area of the contact surface 76 where the base plate 75 is in contact with the main control board 50 (the area indicated by Sqα in FIG. 8) is the area of the opening 67 of the cover body 61 (Sqβ in FIG. 8). Larger than the area shown). In the conventional case, the area of the opening is larger than the area of the contact surface as shown in FIG. However, as shown in the configuration of this embodiment, the exposed portion of the control board (main control board 50) as viewed from the opening 67 is covered with the base plate 75 and disappears. Accordingly, foreign matters such as wires come into contact with the base plate, so that it is possible to prevent fraud with respect to the control board.

  Further, as understood from the cross-sectional view of FIG. 8, in addition to the area size comparison (Sqα> Sqβ), the anti-fraud portion 63 is provided, so that the foreign matter X such as the wire is more in the control board than the anti-fraud portion 63. It is difficult to proceed in the central direction (left direction in the figure), and safety against fraud is improved. The fraud prevention part 63 of an Example is located facing the three surfaces of the main-body part 71 (side wall 73) in the connection part 70 (refer FIG. 7). Further, the height of the connecting portion 70 is substantially the same as the height of the opening 67 of the cover body 61, or the height of the connecting portion 70 is increased, so that the space portion 67o is made as small as possible. Therefore, as compared with the case where the height of the connection portion 70 is lower than the height to the opening portion 67, the height of the connection portion 70 is equal to or higher than the height to the opening portion 67. The risk of being inserted can be reduced.

  When the base plate 75 is made of resin, it is pointed out that the base plate may warp due to deformation. Therefore, as shown in FIG. 9A, the four corners of the connecting portion (base plate) are separately controlled using screws V. It can also be fixed to the substrate. Further, like the connecting portion 70A shown in FIG. 9B, the main body portion 71a can be formed into a substantially trapezoidal shape in a side view, and the side wall can be tapered. When the connection portion 70A is used, the formed space portion 67o is further reduced, and the entry of foreign matter can be suppressed and the safety against fraud can be improved.

  Instead of the integrally formed connecting portion 70 described so far, a connecting portion 70B shown in FIG. 10A can be exemplified. In the connection portion 70B, the main body portion 71b and the base plate 75b are formed separately. The base plate 75b is formed with a through hole 101 through which the main body 71b can be inserted or penetrated. An engaging portion 105 is formed by the main body convex portion 107 provided in the main body portion 71b and the base plate concave portion 108 provided in the base plate 75b.

  As shown in FIG. 10B, when the main body portion 71b is fitted into the through-hole 101 of the base plate 75b, the main body convex portion 107 is engaged with the base plate concave portion. Therefore, the main body 71b and the base plate 75b are attached and are not easily detached. Of course, it is also possible to fix the base plate to the main body part by frictional resistance between the through-hole and the main body part without providing such an engaging part. When the connection portion 70B is formed as a separate body, the replacement due to the breakage of the base plate or the main body portion can be facilitated. For example, there may be a replacement when the above-described base plate is warped up. Incidentally, even if the connecting portion 70A has a main body portion that is substantially trapezoidal in a side view, the main body portion and the base plate can be separated.

  As described above, it is possible to improve the safety against the intrusion of dust and the like from the opening 67 and the insertion of foreign matter (intervention of fraud).

  Next, a second embodiment will be disclosed. The control board housing case 60K shown in FIG. 11 also covers and holds the main control board 50 to protect the electronic components on the control board. The main control board 50 is disposed on the case body 61, and a cover body 95 is attached to the case body 61. An appropriate number of connection portions 80 (connection portions of the second embodiment) are mounted on the main control board 50, and the connector member 205 of the connection member 200 is inserted through the opening 97 of the cover body 95 to be connected. The unit 80 is detachably connected.

  Next, the connection unit 80 will be described with reference to FIG. The connection portion 80 includes a main body portion 81 that allows the terminal portion 202 of the connection member 200 (the connector member 205 shown in FIG. 3 in the embodiment) to be detachable, and the main body portion 81 as a control board (the main control board 50 is exemplified). It comprises a base plate 85 to be attached. The main body 81 has a substantially rectangular parallelepiped shape surrounded by a side wall 83 having a hollow inside. A hollow portion inside the main body becomes an insertion port 82, and the connector member 205 is attached to the insertion port 82. The base plate 85 is formed to extend outward from the side wall 83, and a first protrusion 88 is formed in a wall shape so as to surround the periphery of the base plate. The base plate 85 can cover at least a part of the control board (main control board 50).

  The hatched portion shown in FIG. 12B is the insertion port 82, and the area of the insertion port 82 (that is, the area of the hatched portion) is the area of the opening 97 as can be seen from FIG. It is made smaller. In the figure, reference numeral T denotes a connection terminal, and the connection terminal is inserted into the connector member and engaged therewith. As shown in FIG. 12C, the connection terminal T penetrates the base plate 85. The connection terminal protruding below the base plate is soldered to the control board (not shown), and the connection part is fixed to the control board. Reference numeral 86 denotes a contact surface of the base plate.

  The structure in the vicinity of the connecting portion 80 will be described with reference to a schematic cross-sectional view of the main part of the control board housing case 60K shown in FIG. As illustrated, the connection terminals T of the connection portion 80 (the main body portion 81 and the base plate 85) are attached to the control board (the main control board 50 is exemplified) with solder H. The fixing between the main control board 50 and the case body 61 and the fixing between the cover body 95 and the case body 61 are the same as described above, and will be omitted.

  The structure near the opening 97 in this embodiment will be described. The first protrusions 88 provided around the base plate 85 of the connection part 80 protrude toward the cover body 95 side. A second protrusion 92 projects from the peripheral edge 96 forming the opening 97 of the cover body 95 toward the base plate 85 side. At the same time, the first protrusion 88 is located on the outer side of the second protrusion 92 (the direction of the base of the second protrusion, that is, the peripheral edge 96), and the first protrusion 88 and the second protrusion 92 are respectively Are superposed in the height direction (projecting direction) (overlapping each other). More specifically, the second protrusion 92 is engaged so as to cover the first protrusion 88 (the protrusions are fitted and fitted together). Because of such engagement, the opening 97 and the connecting portion 80 can be easily positioned (aligned).

  A very small space 97 o is formed between the side wall 83 of the connecting portion 80 and the peripheral edge 96 of the opening in the cover body 95, particularly between the side wall 83 and the second protrusion 92. A fraud prevention portion 93 that is a third protrusion is provided at the base of the peripheral edge 96 toward the base plate 85 side. When the cover body 95 is covered with the main control board 50 (and the case body 61), the fraud prevention section 93 is located facing the outer side of the peripheral edge 85e of the base plate. The 1st protrusion 88 and the 3rd protrusion (tamper prevention part 93) are also superposed | superposed in the height direction (direction which protrudes), (it overlaps mutually).

  As shown in the schematic top view of FIG. 14, the base plate 85 (contact surface 86) is formed larger than the opening 97. That is, the area of the contact surface 86 where the base plate 85 is in contact with the main control board 50 (the area indicated by Sqγ in FIG. 15) is the area of the opening 97 of the cover body 95 (Sqδ in FIG. 15). Larger than the area shown). In the figure, reference numeral 88w is the thickness (width) of the first protrusion, 92w is the thickness (width) of the second protrusion, and both the first protrusion 88 and the second protrusion 92 surround the main body 81. It has a flat frame shape. The third protrusion (tamper prevention portion 93) is located facing the three surfaces of the main body 81 (side wall 83) in the connection portion 80. As shown in the illustrated first and second protrusions 88 and 92, the protrusions have a flat plate shape (i.e., protrusions), and the first and second protrusions are in the shape of protrusions only where they need to be protected. It is also possible to provide it as a protrusion.

  As understood from the sectional view of FIG. 15, in the positional relationship between the first protrusion 88, the second protrusion 92, and the third protrusion (tamper prevention part 93), the second protrusion 92 and the third protrusion ( The fraud prevention part 93) forms a substantially U-shaped protrusion in a sectional view on the peripheral edge 96 of the opening. This is a structure in which the first protrusion 88 enters the recess of the “U” shape that opens downward. Therefore, the path of the foreign matter X is blocked by the second protrusion 92, the first protrusion 88, and the third protrusion (tamper prevention part 93) in addition to the size comparison (Sqγ> Sqδ). For this reason, it becomes difficult for the foreign object X to advance in the center direction (left direction in the figure) of the control board so as to sew between the protrusions, and the safety against fraud is improved. According to the second embodiment, the height of the connecting portion 80 and the height of the opening 97 of the cover body 95 are substantially the same, but the height of both is appropriate.

  According to the second embodiment, since the various protrusions are formed in order of the second protrusion 92, the first protrusion 88, and the third protrusion (tamper prevention part 93) from the main body 81, the cover body Taking into account the deformation of the material (changes in the size, shape, etc. of the opening), the size of the opening can be made appropriate. Accordingly, it is possible to further secure safety against intrusion of dust and the like from the opening 97 and insertion of foreign matter (intervention of fraud) while enhancing the convenience of attaching the cover body. More specifically, since the distance between the opening 97 and the side wall 83 can be increased (lengthened), the assembly work of the cover body 95 and the case body 61 can be performed accurately with a margin. is there. For example, even when the peripheral edge 96 of the opening 97 of the cover body 95 is deformed, the deformed portion of the peripheral edge 96 of the opening can move between the opening 97 and the side wall 83. . Therefore, the assembled state of the cover body 95 and the case body 61 can be accurately maintained.

  In addition, the connection part 80 which concerns on 2nd Example forms the main-body part 81 and the baseplate 85 integrally. Instead of the configuration, it is naturally possible to form the main body and the base plate separately (not shown). Details of the structure formed separately in the connecting portion 80 according to the second embodiment are the same as those described with reference to FIG. Also in the connection part 80 according to the second embodiment, the main body part 81 can be substantially trapezoidal in a side view and the side wall can be tapered.

  The configuration for connecting the control board and the connecting member as described in detail so far is not limited to the connection mode between the control boards, but various functions in which the control board is arranged by controlling the electrical components. It can also be applied to objects (attachment members). Hereinafter, a description will be given with reference to FIG. The front view of FIG. 16A illustrates the image display device 9 as an attachment member on which the control board is disposed. The image display device 9 houses therein a liquid crystal display device (TFT-LCD module) (not shown), and includes a decorative member 121 that decorates the periphery of the liquid crystal display device and the surface of the image display device 9. A control board 130 is fixed to the back surface of the decorative member 121 by screws or the like (not shown). Therefore, the decorative member 121 functions in the same manner as the case body. In the figure, reference numeral 122 denotes an LED.

  FIG. 16B is a schematic partial cross-sectional view of the AA cross section of FIG. As shown in the drawing, the LED 122 is mounted on the control board 130, and the connection portion 70 (the main body 71 and the base plate 75) is also mounted on the control board 130. The control board 130 is covered with a cover body 125, and an opening 127 is formed around the connection part 70. The connection terminal Tc of the connection unit 70 and the connection terminal (electrode) Td of the LED are fixed to the control board 130 with solder H. Also in the cover body 125, the 3rd protrusion (tamper prevention part 123) is provided toward the control board 130 side. Also in this embodiment, the area of the abutting surface where the base plate 75 abuts on the control board 130 is larger than the area of the opening 127.

  As can be understood from FIG. 16, also in the mounting member on which the control board is arranged, the opening part, the connection part, the base plate, the control board, the fraud prevention part, etc. have already been described in detail with reference to FIGS. A similar positional relationship is established. Therefore, even if the foreign object X is inserted, the control board 130 is protected. Of course, the connecting portion is not limited to the illustration, and it is possible to apply the connecting portion 80 and include the second projecting portion 92 like the cover body 95. In addition, the mounting member on which the control board is disposed is not limited to the illustrated image display device, but the control board for electrical components such as the start winning port 10, the big winning port 15, the speaker 8, the launching device HD, and various lamps. The present invention can also be applied to a mounting member on which is arranged.

  The positional relationship between the printed wiring on the control board and the connecting portion (base plate) will be described with reference to FIG. FIG. 17A schematically shows a part of the main control board 50. A wiring pattern C including the printed wiring C10 and the connection point E is laid on the control board, and each printed wiring C10 is connected to the connection point E. A connection terminal T of the connection portion, a capacitor (not shown), a resistor, and the like are soldered to the connection point. A wiring pattern, that is, various printed wirings C10 and connection points E appear immediately below the opening 97 indicated by a two-dot chain line.

  FIG. 17B shows a state in which the connection part 80 is provided on the main control board 50. In the illustrated case, the wiring pattern C (printed wiring C10 and connection point E) located outside the main body 81 is substantially covered with the base plate 85 of the connection unit 80. As described above, since the base plate covers at least a part of the wiring pattern, it is possible to strengthen protection of the internal wiring pattern against dust entering from the opening and foreign matter to be inserted.

  In the conventional control board, it was assumed that foreign matter was inserted from the opening, and the control board was designed to be relatively wide so that the wiring pattern and the connection point were separated from the opening. However, with the configuration of the embodiment, it is also possible to design a wiring pattern in which connection points are arranged immediately below the base plate. Therefore, it is not necessary to design the control board wider than before, and the layout of the wiring patterns on the control board can be made finer (increasing the degree of integration of the wiring patterns) than before, and the control board It is possible to reduce itself.

  The present invention that has been described in detail above will be summarized. FIG. 18 shows the positional relationship of the connecting portion 610 in the conventional substrate housing case 600. The connection portion 610 (corresponding to only the main body portion) is directly provided on the control board 500. The control board 500 is mounted and fixed on the case body 601, and a cover body 605 is attached to the case body 601. An opening 607 is formed between the peripheral edge 606 of the cover body 605 and the connection portion 610. In the conventional substrate housing case 600, the control board is covered only with the contact surface between the connection portion 610 and the control board 500. For this reason, there is a fear that dust or the like enters the space 607o of the opening 607, and that foreign matter Y is inserted (injustice). In particular, when the wiring pattern shown in FIG. 17 is assumed, the wiring pattern, the connection point, and the like are exposed in the space portion 607o. It was pointed out that defense against the act was weak.

  However, as in the present invention, since the connection portion has a base plate and covers at least a part of the control board, the exposure of the wiring pattern, the connection point, etc. is eliminated, and the vulnerability of the above defense can be improved. it can. Further, the connection with the control board can be strengthened (strengthened) by the base plate provided in the connection portion. In addition, in each figure, the same code | symbol is attached | subjected to a common location and the description is abbreviate | omitted.
