FIG. 2 is a view showing a corner portion of a decorative unit constituting the front portion of the upper door 30 of the slot machine M, and FIG. 3 is a view of the inside of the portion shown in FIG. 2 as viewed from the rear side. The decorative unit is arranged in a gate shape so that the above-mentioned upper lamp 33a and the left and right side lamps 33b surround the display window 32. The upper lamp 33a is a speaker having an upper lens unit arranged on the front portion thereof, an upper LED substrate 91 arranged on the back surface of the upper lens unit, and speakers arranged on the left and right side portions on the back surface of the upper lens unit. It has a substrate 62 and a speaker cover 61 arranged on the front portion of the speaker substrate 62, and such an upper lamp 33a constitutes an upper design unit.
Note that FIGS. 2 and 3 show only one of the left and right corners of the gate-shaped design unit.

The speaker cover 61 is made of punching metal exposed to the player side of the slot machine M. Therefore, the speaker cover 61 is a conductor that may be charged, and is charged when, for example, the player's hands come close to each other or come into contact with each other. Here, the speaker cover 61 and the speaker board 62 having the speaker are close to each other, and when the speaker cover 61 is charged, there is a high possibility that the speaker board 62 is also charged. Basically, it is designed to avoid the influence of static electricity (for example, static electricity up to 20,000 volts) by arranging the electronic board etc. at a distance of about 20 mm or more from the charged conductor, but there are space problems and speakers. The speaker cover 61 and the speaker board 62 are not separated by 20 mm or more due to the relationship between the sound and the arrangement of the speaker cover 61, and the speaker cover 61 and the speaker board 62 are close to each other to a distance shorter than 20 mm.

Therefore, as shown in FIG. 3, when the speaker board 62 close to the speaker cover 61 is charged by the charged speaker cover 61, a ground wire 82 for quickly releasing static electricity is connected to the speaker board 62. .. The ground wire 82 is a conductor for grounding that connects the back side of the lamp 33b on the side of the design unit of the upper door 30 from top to bottom to the outside of the slot machine M in a state where one end is screwed to the speaker board 62. It is connected. Further, on the back side of the lamp 33b on the side of the design unit of the upper door 30, an upper LED board 91 that serves as a light source for the upper lamp 33a and a side LED board 92 that serves as a light source for the side lamp 33b are provided. A signal line 81 is provided so as to be connected. Note that, in FIG. 3, the illustration of the connector between the upper LED board 91 and the side LED board 92 of the signal line 81 is omitted. Further, the upper lamp 33a is provided with a logo mark in the central portion thereof, and a conductor 71 is provided on the surface of the logo mark and its vicinity by vapor deposition or plating 9. The conductor 71 formed by plating, vapor deposition, or the like is charged when a person tries to touch it. The conductor 71 of this logo mark has a portion that is separated from the speaker substrate 62 by a distance of less than 20 mm, and it is necessary to connect the ground wire 82 to the speaker substrate 62 as described above. That is, the speaker board 62 is close to the speaker cover 61 which is a conductor and the conductor 71 of the logo mark, and it is necessary to ground the speaker board 62 even if only one of them is close to the conductor 71.

The signal line 81 is arranged substantially horizontally from the upper LED substrate 91 provided on the back portion of the upper lamp 33a toward one of the left and right corners of the upper door, and then the signal line 81 of the lamp 33b on one side. The back surface is arranged substantially vertically downward, and is arranged so as to reach the side LED substrate 92 provided on the back surface portion of the side lamp 33b.

The signal line 81 is provided between the upper LED board 91 and the side LED board 92 on the hook 83 and the hook 84 provided on the back portion of the upper lamp 33a and on the back portion of the side lamp 33b. It is in a state of being locked and held by the hook 88. Further, the ground wire 82 is in a state of being locked and held by the hook 85 and the hook 88 provided on the back surface portion of the side lamp 33b.
The ground wire 82 and the signal wire 81 arranged as described above are arranged close to each other and substantially parallel to each other on the back side of the side lamp 33b. That is, the ground wire 82 is arranged so that noise may be generated in the signal wire 81. A partition member 89 that separates the signal line 81 and the ground wire 82 is provided on the back side of the side lamp 33b in order to suppress the influence of the ground wire 82 on the signal line 81. The partition wall member 89 includes a partition wall (shielding wall) 86 erected on the base plate 87 at one side edge portion along the vertical direction of a vertically long rectangular base plate 87. As described above, the partition wall 86 is a rear portion of the side lamp 33b, which extends vertically and is arranged between the signal line 81 and the ground wire 82 which are parallel to each other in close proximity to each other. The partition member 89 is separated from the ground wire 82 and the signal line 81 by a partition wall 86 that serves as a conductive shield, so as to suppress the generation of noise in the signal line 81 due to the influence of the ground wire 82. It has become. Further, the partition member 89 includes a hook 85 for holding the ground wire 82. The partition member 89 having the partition 86 is made of resin, for example, but may be a conductive sheet metal having a high shielding property, that is, a metal part which is a conductor, or a conductive resin. You may.

Therefore, since the ground wire 82 and the signal wire 81 are separated from each other by the partition wall 86, they are shielded from each other. Therefore, even if the ground wire 82 and the signal wire 81 are arranged close to each other and parallel to each other. Since the generation of noise can be suppressed, the signal line 81 and the ground wire 82 can be intentionally arranged in a state of being close to each other and parallel to each other, and the degree of freedom in wiring layout is increased.
Further, the hook 85 of the hooks for holding the ground wire 82 is provided on the partition member 89, holds the ground wire 82 in one space partitioned by the partition wall 86, and the ground wire 82 is provided with respect to the partition wall 86. It is suppressed that it is arranged in the space on the same side as the signal line 81. The partition member 89 may be provided with a hook for holding the signal line 81 on the space side of the two spaces partitioned by the partition 86 where the ground wire 82 is not arranged.

In such a gaming machine, the partition wall 86 should be arranged between the ground wire 82 and the signal line 81 even if the wiring layout is such that the signal line and the ground wire are close to each other and parallel to each other. Therefore, it is possible to prevent the generation of noise in the signal line 81. Therefore, in the wiring layout of the signal line 81 and the ground wire 82, a layout in which they are arranged close to each other in parallel is also allowed, so that the degree of freedom in the layout is increased and the design becomes easy. The partition wall 86 has a shape that separates the space where the ground wire 82 is arranged and the space where the signal line 81 is arranged in a state where the earth wire 82 and the signal line 81 are arranged substantially in parallel. For example, it may be rib-shaped or wall-shaped.

Further, the signal line 81 and the ground wire 82 described above are arranged in the same manner on the left and right sides of the slot machine M, and the partition wall member 89 having the partition wall 86 is arranged on the left and right sides of the slot machine M. The partition member 89 shown in FIG. 3 is arranged on the right side when viewed from the front. 4 and 5 show the partition member 89 on the left side. The partition member 89 on the left side is arranged on the front side (player side) in the vicinity of the motor 100 that operates the movable accessory. Further, on the front side of the partition wall member 89, a decorative member 110 on which the metal of the side lamp 33b is vapor-deposited is arranged. The motor 100 is provided with a connector 101 to which a harness from a drive control device that drives and controls the motor 100 is connected. Further, the motor 100 is a motor with a speed reducer having a built-in speed reducer, and the output shaft 102 is eccentric with respect to a rotation shaft (not shown) of the motor 100. Therefore, when a pair of motors 100 are arranged on the left and right sides of the slot machine M in the same direction, the main body is arranged from the right side with respect to the output shaft 102 in the present embodiment. As a result, in this embodiment, the connector 101 of the motor 100 on the left side of the motor 100 on the right side is arranged near the decorative member 110 on which the metal is vapor-deposited. In this case, when static electricity flows from the player to the decorative member 110, the static electricity flies from the decorative member 110 to the harness of the connector 101 of the motor 100, causing a problem in the drive control device of the motor 100 to which the harness is connected. There is a risk. Therefore, the partition wall member 89 on the left side is provided so that a protruding portion 115 is arranged between the harness side of the connector 101 of the motor 100 and the decorative member 110 on which metal is vapor-deposited, and the protruding portion 115 is a connector. It shields between the harness connected to the 101 and the decorative member 110, and prevents the harness from approaching the decorative member 110. The right partition wall member 89 does not necessarily require a protrusion 115 because the distance between the connector 101 of the motor 100 and the decorative member 110 is longer than that on the left side, but the right partition wall member 89 has a smaller protrusion than the left. 93 (shown in FIG. 3) is provided.
