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 for LED driver power supply, signal, clock, and ground 76 to 79. For example, two LED drivers 80 and 81 branched from the connector, and protection resistors 82 and 83 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 supply. LEDs 84 to 87 and speaker drive wiring paths 88a to 88d connecting the connectors 73 and 74 are provided. An example of the first circuit unit is a circuit unit including LED drivers 80, 81, LEDs 84 to 87, protection resistors 82, 83, etc., which are connected to the through-pass wiring lines 75 to 79.

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 them to the long side side of the speaker terminals 94a to 94d. It is possible to secure a larger cross-sectional area of the portion and keep the resistance low.

The LEDs 84 to 87 are arranged in a row at substantially constant intervals along the longitudinal direction of, for example, the front wiring layer 71a (FIG. 5A). The LEDs 84 and 85 driven by the LED driver 80 are arranged vertically on the upper side of the front wiring layer 71a, for example, and are connected in series by the wiring path 95 between the LEDs. Further, the LEDs 86 and 87 driven by the LED driver 81 are arranged diagonally along the right edge portion 72a of the board body 72 on the lower side of the front wiring layer 71a, for example, and are connected in series by the wiring path 95 between the LEDs. There is. 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). The electrode) and the B electrode (third electrode) corresponding to the blue color 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, in addition to the speaker drive wiring lines 88a to 88d, the through-pass wiring lines 75 to 78 for the LED power supply, the LED driver power supply, the signal, and the clock are, for example, both ends thereof, that is, the connector. Except for a predetermined range in the vicinity of the connection portions to the 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 are on the rear wiring layer 71b side via vias (interlayer conductive portions) 96 on both ends thereof. It is connected to the speaker terminals 94a and 94b of the connectors 73 and 74.

Further, the anode electrodes of the LEDs 148 and 149 are connected to the LED power supply terminal 89 of the upstream connector 143 via the wiring path 162 for the LED power supply straddling the rear wiring layer 141b side via the via 96, and are connected to the LED power supply terminal 89 of the LED 147 and 150. The cathode electrode is connected to the protection resistors 151 and 152 via the cathode side wiring path 163 that straddles the rear wiring layer 111b side with the via 96 interposed therebetween. Further, the wiring paths 161 between the LEDs, the wiring path 162 for the LED power supply, and the wiring path 163 on the cathode side are provided with heat dissipation portions 105a and 105b similar to those of the first LED substrate 41 and the like.

In the third LED substrate 43, the speaker drive wiring paths 154a to 154d are formed to be wider than the digital signal wiring paths such as the signal and clock wiring lines 156 and 157 for driving the LED.

In the first to third LED boards 41 to 43 described above, through-pass wiring paths are provided straddling the first to third LED boards 41 to 43, but the current value is larger as the LED board on the upstream side is located. Therefore, the through-pass wiring path of the power supply system in the LED board on the upstream side is formed wider than the through-pass wiring path of the power supply system in the LED board on the downstream side thereof. For example, the through-pass wiring paths 75 and 76 for the LED power supply and the LED driver power supply in the first LED board 41 are wider than the through-pass wiring paths 115 and 116 for the LED power supply and the LED driver power supply in the second LED board 42. It is formed.

Further, among the plurality of terminals of the connector for connecting the LED boards, the number of terminals corresponding to the through-pass 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 supply terminals 89a and 89b and the LED driver power supply terminal 90 in the connectors 74 and 113 for connecting the first and second LED boards 41 and 42 is three, while the second and second LED power supply terminals are second. 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 three LED boards 42 and 43 is two.

As a result, while ensuring the required voltage for each LED board, it is not necessary to use a power supply system wiring line that is thicker than necessary or a connector that is larger than necessary for the LED board on the downstream side, thus improving the space efficiency of wiring. It is possible.

Has been done.

Each terminal of the connectors 173 and 174 has, for example, a rectangular shape, and is formed in an elongated shape in a direction orthogonal to the arrangement direction thereof. The blower power supply terminal 190a and the blower ground terminal 190b on both ends of the upstream connector 173 are connected to the blower power supply wiring line 189a and the blower ground wiring line 189b from the outside in the terminal arrangement direction (here, the left-right direction), respectively. Similarly, in the blower power supply terminal 190a and the blower ground terminal 190b on the lower end side of the downstream connector 174, the blower power supply wiring line 189a and the blower ground wiring line 189b are outside the terminal arrangement direction (here, the vertical direction).

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

In the fourth LED board 44, in addition to the ventilation power supply wiring line 189a and the ventilation ground wiring line 189b, through-pass wiring lines 175 to 178 for the LED power supply, the LED driver power supply, the signal, and the clock are provided via the via 96.

The LEDs 245 to 248 are full-color light emitting types with built-in red, green, and blue LED elements. For example, on both the anode side and the cathode side, the R electrode corresponding to red, the G electrode corresponding to green, and blue are used. The corresponding B electrode is provided side by side so that the R electrode is at the center, for example. Further, the anode electrodes of the LEDs 246 and 247 are connected to the LED power supply terminal 89 of the upstream connector 243 via the wiring path 255 for the LED power supply straddling the rear wiring layer 241b side via the via 96, and are connected to the LED power supply terminal 89 of the LED 245 and 248.

Further, at the arrangement position of the LED driver 120 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. It is provided corresponding to 261. In the solid ground pattern 134, the vias 96 are concentratedly arranged in the central region of the LED driver 120 in the arrangement region, but in the present embodiment, the conductor is exposed so as to include the arrangement region of the vias 96. A portion 262 is provided.

Then, the conductor portion 261 on the LED driver 120 side and the conductor exposed portion 262 on the back wiring layer 111b side facing each other are connected by, for example, a solder (conduction connecting means) 263. As a result, heat conduction from the LED driver 120 to the solid ground pattern 134 is promoted as compared with the first embodiment, so that the heat generated by the LED driver 120 can be dissipated more efficiently.

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

Although it may be inferior in terms of heat dissipation effect as compared with 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 the noise picked up by the solid ground pattern 134.

Further, since the via 96 is not applied in the connecting region formed by the solder 263, the LED driver 120 is fixed more firmly than in the case where the via 96 is applied in the connecting region formed by the solder 263 as in the second embodiment. can. In that sense, this embodiment is more effective in the case of a large heat-generating component.

It should be noted that the vias 96 may be arranged not only in the peripheral region in the arrangement region of the LED driver 120 but also in the central region inside the vias 96, and the arrangement density of the vias 96 may be higher in the peripheral region than in the central region. .. In this case, for example, a part of the via 96 may be applied in the connecting region by the solder (conduction connecting means) 263. Further, in the present embodiment, an example in which the conductor portion 261 on the LED driver 120 side and the conductor exposed portion 262 on the rear wiring layer 111b side are connected by solder (conduction connecting means) 263 is shown, but as in the first embodiment.

The layer 141b is connected to the speaker terminals 153c and 153d of the speaker connector 145, respectively.

Further, the solid ground pattern 264 of the intermediate layer 141c constitutes the ground wiring path 160 together with the solid ground pattern 159 on the front wiring layer 141a side, the solid ground pattern 158 on the rear wiring layer 141b side, and the like, for example, via 96 and solid.

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 applied to both layers of the intermediate layer (both intermediate layers or an intermediate layer and one surface layer). It is desirable to provide it.

For example, if the wiring path for transmitting a signal to the LED driver is long, the waveform may be disturbed due to the influence of noise etc. on the way, but the LED looks normal even if there is some disturbance in the waveform. It is difficult to determine whether or not the input signal to the LED driver is normal from the light emitting state of the LED. Therefore, for example, 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, is the waveform of the signal input to the LED driver normal? It is possible to accurately verify whether or not it is. It is desirable that the test point is provided as close as possible to the LED driver. Further, although the test point may be provided exclusively for it, a via such as a through hole may be used as the test point.

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" and others are used near the test points on the board. It is desirable to provide a mark for.

Further, although an example in which the present invention is applied to a pachinko machine is shown in the embodiment, it can be similarly carried out in various gaming machines such as an arrange ball machine and a slot machine.
