The width is gradually increased, and a notch 72c corresponding to the position of the left upper second speaker 38a is formed in the lower left portion.

  As shown in FIG. 4, the first LED substrate 41 has an upstream connector (substrate connection connector) 73, a downstream connector (substrate connection connector) 74, and an LED for connecting the connectors 73, 74. Through-pass wiring paths (predetermined wiring paths) 75 to 79 for power supply, LED driver power supply, signal, clock and ground, and through-pass wiring paths 76 to 79 for LED driver power supply, signal, clock and ground For example, two LED drivers 80 and 81 that are branched and connected, and protective resistors 82 and 83 that are connected in series between the RGB terminals of the LED drivers 80 and 81 and the through-pass wiring path 75 for the LED power source, and LEDs 84 to 87 and speaker drive wiring paths 88a to 88d for connecting the connectors 73 and 74 are provided. A circuit unit including the LED drivers 80 and 81, the LEDs 84 to 87, the protective resistors 82 and 83, and the like connected to the through-pass wiring paths 75 to 79 is an example of the first circuit unit.

  The upstream connector 73 is connected to the front door relay board 56 via the harness 60. For example, the two LED power terminals 89a and 89b to which the LED power through-pass wiring path 75 is connected and the LED driver power supply are connected. For example, one LED driver power supply terminal 90 to which the through-pass wiring path 76 is connected, for example one signal terminal 91 to which the signal through-path wiring path (digital signal wiring path) 77 is connected, and a clock through-path wiring path For example, one clock terminal 92 to which (digital signal wiring path) 78 is connected, three ground terminals 93a to 93c to which ground through-pass wiring path 79 is connected, and speaker drive wiring paths 88a to 88d are connected.

Then, two terminals on both ends in the terminal arrangement direction of the two rows, that is, a total of four terminals are speaker terminals 94a to 94d. In this way, the through-path wiring path 75 for the LED power supply is connected to the two LED power supply terminals 89a and 89b, and the through-path wiring path 79 for the ground is connected to the three ground terminals 93a to 93c. This reduces the electrical resistance generated at the contact area.

  For the eight terminals other than the speaker terminals 94a to 94d in the connectors 73 and 74, for example, the LED power terminals 89a and 89b, the ground terminal 93a, and the LED driver power terminal 90 are arranged in that order in one row. A ground terminal 93b, a signal terminal 91, a clock terminal 92, and a ground terminal 93c are arranged in that order in the column on the side. Of course, the arrangement of the terminals in the connectors 73 and 74 is arbitrary.

  FIG. 5 shows a specific wiring pattern of the first LED substrate 41 for each wiring layer. In the first LED board 41, LEDs 84 to 87 and the like are provided on the front wiring layer (second wiring layer) 71a on the front side, and the upstream connector 73, the downstream connector 74, and the like on the back wiring layer (first wiring layer) 71b on the back side. LED drivers 80 and 81, protective resistors 82 and 83, etc. are arranged, respectively.

  The front wiring layer 71a and the back wiring layer 71b are substantially entirely covered with the insulating film 106 (see FIG. 7), but in FIG. The lower wiring path and the like are indicated by solid lines. The same applies to FIG. 8, FIG. 10, FIG. 12, FIG. 14, and FIG.

Each terminal of the connectors 73 and 74 has, for example, a rectangular shape and is formed in an elongated shape in a direction orthogonal to the arrangement direction. The speaker terminals 94a and 94b on one end side of the upstream connector 73 are connected to, for example, speaker drive wiring paths 88a and 88b for the upper first speaker 36a from the outside in the terminal arrangement direction (herein, left and right direction), and upstream. For example, speaker drive wiring paths 88c and 88d for the upper first speaker 36b are connected to the speaker terminals 94c and 94d on the other end side of the side connector 73 from the outside in the terminal arrangement direction (here, the left-right direction). Similarly, for example, speaker drive wiring paths 88a and 88b for the upper first speaker 36a are connected to the speaker terminals 94a and 94b on one end side of the downstream connector 74 from the outside in the terminal arrangement direction (herein, the vertical direction), and downstream. For example, speaker drive wiring paths 88c and 88d for the upper first speaker 36b are connected to the speaker terminals 94c and 94d on the other end side of the side connector 74 from the outside in the terminal arrangement direction (here, the vertical direction).

Although the speaker drive wiring paths 88a to 88d are formed wide, it is easy to avoid interference with other wiring paths. Further, since the speaker terminals 94a to 94d are formed in an elongated shape in a direction orthogonal to the terminal arrangement direction, the speaker drive wiring paths 88a to 88d are connected by connecting to the long sides of the speaker terminals 94a to 94d. It is possible to secure a larger cross-sectional area of the portion and to keep the resistance low.

  The LEDs 84 to 87 are arranged in a line at substantially constant intervals along the longitudinal direction of the front wiring layer 71a (FIG. 5A), for example. The LEDs 84 and 85 driven by the LED driver 80 are vertically arranged on the upper side of the front wiring layer 71 a, for example, and are connected in series by an inter-LED wiring path 95. The LEDs 86 and 87 driven by the LED driver 81 are disposed obliquely along the right edge portion 72a of the substrate body 72 on the lower side of the front wiring layer 71a, for example, and are connected in series by the inter-LED wiring path 95. Yes. The LEDs 84 to 87 are full-color light emitting types incorporating red, green, and blue LED elements. For example, on both the anode side and the cathode side, an R electrode corresponding to red and a G electrode corresponding to green (second) Electrode) and a B electrode (third electrode) corresponding to blue are provided side by side so that, for example, the R electrode (first electrode) is in the center.

  Further, in the first LED board 41, the speaker drive wiring paths 88a to 88d, as well as the LED power supply, LED driver power supply, signal and clock through-pass wiring paths 75 to 78, for example, both ends thereof, that is, connectors. Except for a predetermined range in the vicinity of the connection portion to 73 and 74, substantially all of them are provided on the same front wiring layer (second wiring layer) 71a side as the LEDs 84 to 87.

  That is, the speaker drive wiring paths 88a and 88b are arranged on the front wiring layer 71a along, for example, the right edge portion 72a, and on both ends thereof via vias (interlayer conductive portions) 96, the rear wiring layer 71b side. The connectors 73 and 74 are connected to speaker terminals 94a and 94b. The speaker drive wiring paths 88c and 88d are arranged on the front wiring layer 71a along, for example, the left edge portion 72b, and the speakers in the connectors 73 and 74 on the rear wiring layer 71b side via the vias 96 at both ends. The terminals 94c and 94d are connected. The via 96 of this embodiment is assumed to be a through-hole type via in which a through hole is plated.

  The through-pass wiring paths 75 to 78 for LED power supply, LED driver power supply, signal and clock are, for example, the front wiring layer 71a along the right side of the upper side LEDs 84 and 85 and the left side of the lower side LEDs 86 and 87. The LED power terminals 89a and 89b, the LED driver power terminals 90, and the signals of the connectors 73 and 74 on the back wiring layer 71b side are connected via vias 96 at both ends thereof.

For example, speaker drive wiring paths 128c and 128d for the upper first speaker 36b are connected to the speaker terminals 94c and 94d on the other end side of the side connector 113 from the outside in the terminal arrangement direction (here, the left-right direction). Similarly, for example, speaker drive wiring paths 128a and 128b for the upper first speaker 36a are connected to the speaker terminals 94a and 94b on one end side of the downstream connector 114 from the outside in the terminal arrangement direction (here, the left-right direction), and downstream.

Although provided on the wiring layer 111 a side, the LED driver power supply, signal and clock through-pass wiring lines 116 to 118 in addition to the speaker driving wiring lines 128 a to 128 d are connected to the front wiring layer 111 a via the via 96. Except for some bypass parts to avoid on the side, almost all of them are provided on the back wiring layer 111b side.

Thus, since the downstream connector 114 of the second LED board 42 is disposed in the middle of the wiring path connecting the upstream connector 113 and the LED driver 120, the downstream connector 114 is located on the lowermost side of the second LED board 42. There is an advantage that the wiring path of the second LED substrate 42 is simplified as compared with the case where 114 is arranged.

For example, the LED power supply and LED driver power supply through-pass wiring lines 75 and 76 on the first LED board 41 are wider than the LED power supply and LED driver power supply through-pass wiring lines 115 and 116 on the second LED board 42. Is formed.

  Further, among the plurality of terminals of the connector for connecting the LED boards, the number of terminals corresponding to the through-path wiring path of the power supply system is larger in the upstream connector than in the downstream connector. For example, the total number of LED power terminals 89a and 89b and LED driver power terminals 90 in the connectors 74 and 113 for connecting the first and second LED boards 41 and 42 is three, whereas the second and second LED power terminals 90 and 90 are three. The total number of LED power supply terminals 89 and LED driver power supply terminals 90 in the connectors 114 and 143 for connecting the 3LED substrates 42 and 43 is two.

  As a result, while securing the necessary voltage for each LED board, it is not necessary to use a power system wiring path thicker than necessary or a connector larger than necessary in the downstream LED board, thereby increasing the wiring space efficiency. It is possible.

Since they are connected, it is easy to avoid interference with other wiring paths, although the blowing power supply wiring path 189a and the blowing ground wiring path 189b are formed wide. Further, since the blower power supply terminal 190a and the blower ground terminal 190b are formed in an elongated shape in a direction orthogonal to the terminal arrangement direction, the blower power supply wiring path 189a and the blower ground wiring path 189b are connected to the blower power supply terminal 190a, By connecting to the long side of the blower ground terminal 190b, a larger cross-sectional area of the connecting portion can be secured.

However, for example, the LED driver 180 is intensively arranged in the central area in the arrangement area of the LED driver 180. Accordingly, the LED driver 180 can effectively dissipate heat through the solid ground pattern 196 and the via 96, and adverse effects due to noise picked up by the solid ground pattern 196 can be eliminated as much as possible.

  The LEDs 183 to 186 driven by the LED driver 180 are arranged in a line at a substantially constant interval in the longitudinal direction (vertical direction) of the front wiring layer 171a, for example.

In this way, by arranging a plurality of via groups obliquely with respect to the terminal arrangement direction of the upstream connector 213 and substantially parallel to each other, the vias 96m to 96r can be prevented from interfering with each other and high space efficiency can be achieved. It is possible to arrange with.

  On the front wiring layer 211a side, as shown in FIG. 15A, the LED drive wiring paths 239a to 239c are led out from the vias 96m to 96o, for example, upward in parallel with each other, and the LED drive wiring paths 240a to 240c. Are drawn from the vias 96p to 96r, for example, in a downward direction substantially parallel to each other. Thus, the lead-out directions of the LED drive wiring paths 239a to 239c and 240a to 240c on the front wiring layer 211a side are different between the first via group and the second via group.

  The LED power supply wiring paths 231 and 232, the inter-LED wiring paths 235 and 237, and the cathode side wiring paths 236 and 238 are provided with heat radiation portions 105a and 105b similar to the first LED substrate 41 and the like. Further, in the fifth LED board 45, the blower power supply wiring path 228a and the blower ground wiring path 228b are wider than the digital signal wiring paths such as the signal and clock through-pass wiring paths 217 and 218 for driving the LED. Is formed.

[Sixth LED board 46]
As shown in FIG. 3, the sixth LED substrate 46 includes, for example, a substantially donut-shaped substrate body 242 having wiring layers on both front and rear surfaces. As shown in FIG. 11, the board main body 242 is provided with an upstream connector 243, LED drivers 244, LEDs 245 to 248, protective resistors 249 and 250, and the like. The upstream connector 243 is connected to the downstream connector 214 on the fifth LED substrate 45 side by the harness 67, and has the same terminal configuration as the downstream connector 214.

  FIG. 16 shows a specific wiring pattern of the sixth LED substrate 46 for each wiring layer. In the sixth LED board 46, the LEDs 245 to 248 are arranged on the front wiring layer 241a (FIG. 16A) on the front side, and the upstream connector 243, the LED driver 244 are arranged on the rear wiring layer 241b (FIG. 16B) on the back side. Protection resistors 249, 250, etc. are arranged respectively.

  The upstream connector 243 is disposed, for example, on the lower side of the back wiring layer 241 b so that the terminal arrangement is substantially in the circumferential direction of the substrate body 242. The LED driver 244 is disposed at a position away from the upstream connector 243 in the back wiring layer 241b. For example, protective resistors 249 and 250 connected to the RGB terminals of the LED driver 244 are disposed on both sides thereof. The LED driver power supply terminal 90, the signal terminal 91, the clock terminal 92, and the LED driver 244 of the upstream connector 243 are connected by the wiring paths 251 to 253 for the LED driver power supply, the signal, and the clock. The LED driver power supply, signal, and clock wiring paths 251 to 253 are, for example, substantially all provided on the back wiring layer 241b side.

  The LEDs 245 to 248 are arranged, for example, at a substantially constant interval in the circumferential direction of the front wiring layer 241a. For example, the LEDs 245 and 246 and the LEDs 247 and 248 are connected by an inter-LED wiring path 254, respectively. The LEDs 245 to 248 are full-color light emitting types that incorporate red, green, and blue LED elements. For example, on both the anode side and the cathode side, an R electrode corresponding to red, a G electrode corresponding to green, and a blue color are used. Corresponding B electrodes are provided side by side so that, for example, the R electrode is in the center. Further, the anode electrodes of the LEDs 246 and 247 are connected to the LED power terminal 89 of the upstream connector 243 via the via 96 and the LED power wiring line 255 extending over the back wiring layer 241b. The cathode electrode is connected to the protective resistors 249 and 250 via a cathode side wiring path 256 that straddles the back wiring layer 241b side with the via 96 interposed therebetween. The inter-LED wiring path 254, the LED power supply wiring path 255, and the cathode-side wiring path 256 are provided with heat radiation portions 105a and 105b similar to the first LED substrate 41 and the like.

  For example, a solid ground pattern 257 is provided on the front wiring layer 241a. The solid ground pattern 257 constitutes a ground wiring path 259 together with the solid ground pattern 258 on the back wiring layer 241b side, and the ground terminals 93a, 93a of the upstream connector 243 via the via 96, the solid ground pattern 258, etc., for example. 93b and the ground terminal of the LED driver 244.

  A part of the solid ground pattern (first conductor pattern) 258 is disposed between the LED driver 244 and the substrate body 242. Of the vias 96 that connect the solid ground pattern 258 and the solid ground pattern (ground wiring path, second conductor pattern) 257 on the front wiring layer 241a side, the vias arranged in the arrangement region of the LED driver 244. 96 is arranged, for example, in the vicinity of one edge of the LED driver 244 in accordance with the arrangement of the solid ground pattern 257 on the front wiring layer 241a side, for example.

  In the right wiring path 58 described above, among the plurality of terminals of the connector for connecting the LED boards, the number of terminals corresponding to the through-path wiring path of the power supply system is that of the upstream connector rather than the downstream connector. There are more. For example, the total number of LED power terminals 89a and 89b and LED driver power terminals 90 in the connector 173 for connecting the front door relay board 56 and the fourth LED board 44 is three, whereas the fourth and fifth LEDs The total number of LED power supply terminals 89 and LED driver power supply terminals 90 in the connectors 174 and 213 for connecting the substrates 44 and 45 is two.

  Accordingly, it is possible to increase the space efficiency of the wiring because it is not necessary to use a connector larger than necessary in the downstream LED board while securing a necessary voltage for each LED board.

  FIG. 17 illustrates the second embodiment of the present invention. A part of the first embodiment is modified to provide a conductor part on the back surface of the LED driver, and the conductor part and the solid ground pattern are connected by solder. An example is shown.

  The LED driver 120 of the second LED substrate 42 (see FIG. 8) will be described as an example. The LED driver (heat-generating component) 120 of this embodiment includes a copper foil and other conductors 261 on the back surface thereof. The conductor portion 261 is formed in, for example, a rectangular shape corresponding to the center of the back surface of the LED driver 120. Of course, the shape of the conductor part 261 is arbitrary, and the conductor part 261 may be provided on substantially the entire back surface of the LED driver 120.

  Further, at the position where the LED driver 120 is disposed on the back wiring layer 111b of the second LED substrate 42, a conductor exposed portion 262 in which a part of the solid ground pattern 134 is exposed from the insulating film 106 is, for example, a conductor portion on the LED driver 120 side. 261 corresponding to H.261. In the solid ground pattern 134, the vias 96 are intensively arranged in the central region in the arrangement region of the LED driver 120. In this embodiment, the conductor is exposed so as to include the arrangement region of the vias 96. A portion 262 is provided.

  The conductor part 261 on the LED driver 120 side and the conductor exposed part 262 on the back wiring layer 111b side which are opposed to each other are connected by, for example, solder (conduction connecting means) 263. Thereby, since heat conduction from the LED driver 120 to the solid ground pattern 134 is promoted as compared with the first embodiment, heat generated in the LED driver 120 can be radiated more efficiently.

  The same configuration can be adopted for the LED drivers arranged on the other LED boards 41, 43, etc. in addition to the other LED drivers 121 of the second LED board 42.

  FIG. 18 illustrates a third embodiment of the present invention. A part of the second embodiment is modified so that a plurality of vias (interlayer conductive portions) provided in the LED driver arrangement region are replaced with the LED driver. An example is shown in which it is arranged not in the central area in the arrangement area but in the peripheral area in the arrangement area.

  In the second LED substrate 42 of the second embodiment, as shown in FIG. 17, a part of the solid ground pattern 134 is disposed between the LED driver 120 and the substrate body 112, and the solid ground pattern 134 and the front wiring layer are arranged. Vias 96 that connect to the solid ground pattern 135 on the 111a side are concentrated in the central area in the arrangement area of the LED driver 120. In this embodiment, as shown in FIG. 96 are arranged substantially equally in the peripheral area outside the central area in the arrangement area, not in the central area in the arrangement area of the LED driver 120.

  Moreover, the LED driver 120 of this embodiment is equipped with the copper foil and other conductor parts 261 on the back surface similarly to 2nd Embodiment. The conductor portion 261 is formed in, for example, a rectangular shape corresponding to the center of the back surface of the LED driver 120. Further, at the position where the LED driver 120 is disposed on the back wiring layer 111b of the second LED substrate 42, a conductor exposed portion 262 in which a part of the solid ground pattern 134 is exposed from the insulating film 106 is, for example, a conductor portion on the LED driver 120 side. 261 corresponding to H.261. In addition, the conductor exposed part 262 of this embodiment is provided in the range which does not reach the via | veer 96 provided in the peripheral region in the arrangement | positioning area | region of the LED driver 120. FIG.

  The conductor part 261 on the LED driver 120 side and the conductor exposed part 262 on the back wiring layer 111b side which are opposed to each other are connected by, for example, solder (conduction connecting means) 263. As described above, when the plurality of vias (interlayer conductive portions) 96 provided in the arrangement area of the LED driver 120 are arranged in the peripheral area in the arrangement area of the LED driver, as in the second embodiment. Although it may be inferior in terms of heat dissipation effect compared to the case where it is arranged in the central region, it is considered to be superior in terms of eliminating the adverse effect on the LED driver 120 due to noise picked up by the solid ground pattern 134.

  Further, since the via 96 is not applied in the connection region by the solder 263, the LED driver 120 is more firmly fixed as compared with the case where the via 96 is applied in the connection region by the solder 263 as in the second embodiment. it can. In that sense, this embodiment is more effective for large exothermic parts.

  The vias 96 may be arranged not only in the peripheral area in the arrangement area of the LED driver 120 but also in the central area inside thereof, and the arrangement density of the vias 96 may be higher in the peripheral area than in the central area. . In this case, for example, a part of the via 96 may be placed in a connection region by the solder (conducting connection means) 263. Further, in this embodiment, the example in which the conductor portion 261 on the LED driver 120 side and the conductor exposed portion 262 on the back wiring layer 111b side are connected by solder (conduction connecting means) 263 is shown, but as in the first embodiment It is not necessary to perform connection by the conductive connection means.

In addition, by providing a driving wiring path formed wider than the LED wiring path in the intermediate layer, the space of the surface layer can be used more effectively and the substrate can be downsized. When two or more intermediate layers are provided, for example, a drive wiring path is provided in one of the intermediate layers, and a solid ground pattern is provided on both sides of the intermediate layer (both the intermediate layer or the intermediate layer and one surface layer). It is desirable to provide it.

You may provide the relay wiring path which connects LED (3rd LED) 245-248 of the board | substrate (3rd board | substrate) 46. FIG.

  In the embodiment, in the first and third LED substrates 41 and 43, LED drivers 80, 81 and 146 are provided on the back wiring layers (first wiring layers) 71b and 141b, and the other front wiring layers (second wiring layers) 71a. 141a are provided with drive wiring paths 88a to 88d and 154a to 154d for driving the speakers 36a and 36b, respectively. However, an LED driver is provided in the first wiring layer, and an air blowing effect means 37 is provided in the second wiring layer. You may provide the drive wiring path regarding movable production | presentation means, such as. In this case, you may provide LED in a 2nd wiring layer. Alternatively, as in the fourth embodiment, an LED driver may be provided in the first wiring layer as the surface layer, and a driving wiring path related to the movable effect means such as the air blowing effect means 37 may be provided in the second wiring layer as the intermediate layer. .

  In the second embodiment, the conductor exposure is performed so as to include the arrangement regions of the vias 96 so as to correspond to the vias 96 intensively arranged in the central region in the arrangement region of the LED driver 120 in the solid ground pattern 134. Although the example in which the portion 262 is provided has been shown, the conductor exposed portion 262 and the conductor portion 261 are provided corresponding to the peripheral region so as not to reach the via 96 disposed in the central region, and they are soldered (conducting connection means) ) 263 may be connected.

  In the embodiment, the wiring paths such as the first to sixth LED substrates 41 to 46 arranged on the front door 8 are branched into the left wiring path 57 on the left side and the right wiring path 58 on the right side below the window hole 34. The first to sixth LED substrates 41 to 46 may be connected in series, for example, in the order of the substrates 41, 42, 43, 46, 45, 44, or vice versa, without branching on the way.

  In the embodiment, the LED board disposed on the front door 8 has been described. However, the LED board disposed on a gaming component such as the central display unit 22 in the gaming board 5 can be similarly implemented. Further, the present invention can be similarly applied to a substrate other than the LED substrate, such as an effect control substrate.

  Measurement points (hereinafter referred to as test points) for verifying the waveform of a signal input to the LED driver may be provided on the wiring path. For example, if the wiring path for transmitting the signal to the LED driver is long, the waveform may be disturbed due to the influence of noise or the like on the way, but the LED is normally normal even if there is some waveform disturbance Therefore, it is difficult to determine whether the input signal to the LED driver is normal from the light emission state of the LED. Therefore, for example, whether the waveform of the signal input to the LED driver is normal by providing a test point in the signal wiring path, clock wiring path, etc. connected to the LED driver and measuring the waveform of the signal at the test point. It is possible to accurately verify whether or not. The test point is preferably provided as close as possible to the LED driver. In addition, although the test point may be provided exclusively for it, a via such as a through hole may be used as the test point.

  For example, in the case where test points are provided on a plurality of wiring paths drawn substantially in parallel from a plurality of terminals arranged in a predetermined direction, as shown in the embodiments (FIGS. 13, 15, 23 to 25, etc.). The vias may be arranged in the same manner as the arrangement of the vias (diagonal, zigzag, etc.). In addition, in order to distinguish between vias such as through holes and test points, or to clearly indicate that they are through holes used as test points, characters such as “TP” in the vicinity of test points on the board, etc. It is desirable to provide a mark.

  In the embodiment, an example in which the present invention is applied to a pachinko machine has been described. However, the present invention can be similarly applied to various game machines such as an arrange ball machine and a slot machine.
