DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rail decoration mounted on a pachinko game machine along a pachinko ball guiding rail on the front of a game board.

[0002]

2. Description of the Related Art A lamp decoration body conventionally provided on a game board surface inside a pachinko ball guiding rail is provided with several miniature bulbs or bullet-shaped LEDs inside a transparent plastic case. The thickness was more than 3 cm. For this reason, a large arc-shaped mounting hole is provided inside the ball guide rail of the game board in a penetrating manner, and the rear portion of the lamp decoration is placed in the mounting hole so that it can be accommodated in the front glass of the game board. It had to be attached.

[0003]

However, opening such a large mounting hole requires processing man-hours, which has a drawback that mounting is not easy, and also has a problem that the strength of the game board is impaired by the processing. Was.

SUMMARY OF THE INVENTION A rail decorative body of a pachinko game machine according to the present invention is intended to solve the above problems.
A mounting board formed in a constant-width arc shape, a fixed-width arc-shaped printed wiring board in which a plurality of light emitting diodes are arranged on the front surface, and a power supply wiring member is protrudingly provided on the back surface, and a constant-width arc-shaped light transmitting plate The mounting board is formed with a narrow concave groove and a narrow convex ridge which are concave and convex on the back surface, and the printed wiring board is formed in the narrow concave groove. The light-emitting diode is exposed through a plurality of window holes provided in the narrow ridge, and the light-transmissive cover is attached to the narrow ridge, and the light-emitting diode is set on the game board. The power supply wiring member faces the small hole, and the mounting board is fixed along the ball guide rail on the game board surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of the front surface of the rail decoration, FIG. 2 is an exploded perspective view of the back surface, FIG. 3 is a perspective view of the assembled state, and FIG. 4 is a sectional view taken along line AA of FIG. In the figure, reference numeral 1 denotes a plastic mounting substrate formed as a whole with a constant-width circular arc shape. . The mounting substrate 1 is formed with a narrow concave groove 4 and a narrow convex ridge 5 which are concave on the back surface and protrude on the front surface, respectively. Have been. 7 is an engagement hole formed in the inner edge of the narrow-width ridge 5;
Reference numeral 8 denotes screw holes formed at both ends and an intermediate portion of the narrow-width convex ridge 5, and reference numeral 9 denotes a positioning hole.

Reference numeral 10 denotes a fixed-width arc-shaped printed wiring board on which a plurality of chip-shaped light emitting diodes 11 are soldered on a front surface and a connector 12 for supplying power to each of the light emitting diodes 11 is protruded on a back surface. It is. 13
Denotes a resistor provided for adjusting the voltage applied to the light emitting diode 11, and 14 denotes screw holes formed at both ends and an intermediate portion of the printed wiring board 10. Also, 1
Reference numeral 5 denotes a light-transmissive cover body having a constant-width circular arc shape formed of a translucent plastic such as acrylic.
5 has a convex lens-like cross section as shown in FIG. 4, and its inner surface 16 is formed with a concave-convex unevenness for diffusing light. Reference numeral 17 denotes screw holes formed at both ends and an intermediate portion of the rear surface of the light-transmitting cover body 15, reference numeral 18 denotes an engagement piece extending on the inner peripheral edge of the light-transmitting cover body 15, and reference numeral 19 denotes a positioning pin. is there.

A printed wiring board 10 is accommodated in the narrow concave groove 4 of the mounting board 1 so that the light emitting diode 11 is exposed forward from the window hole 6 and light is transmitted through the narrow convex ridge 5 of the mounting board 1. The positioning cover 19 is fitted to the positioning hole 9, the engaging piece 18 is engaged with the engaging hole 7, and the screw 30 is screwed into the screw holes 14, 8, 17 from behind. By the combination, the mounting board 1, the printed wiring board 10, and the translucent cover body 15 are assembled. When the rail decoration is mounted on the game board 20 of the pachinko game machine as shown in FIG. 5, the connector 12 is provided inside the ball guide rail 21 of the game board 20 as shown in FIG. A small hole 22 capable of transmitting light is opened, the connector 12 faces the small hole 22, the mounting board 1 is arranged along the ball guide rail 21 on the game board 20, and a wood screw 23 is inserted into the nail hole 3. Screw it in and fasten it. Then, by connecting the power cord 24 to the connector 12 from the back side of the game board 20, each of the light emitting diodes 11 blinks. Reference numeral 31 denotes a front glass plate of the game board 20.

[0008] This rail decoration is a light emitting diode 11
Can be made thin by being directly attached to the printed wiring board 10, and the printed wiring board 10 can be completely accommodated in the narrow groove 4 of the mounting board 1. 22 can be easily installed simply by opening it. Further, since it can be formed to be narrower than the conventional one using a miniature bulb, there is an advantage that even if it is disposed inside the ball guide rail 21, the game board surface can be widely used without obstructing the falling of the pachinko balls.

[0009]

As described above, according to the rail decorative body of the present invention, a small hole for penetrating a power supply wiring member such as a connector can be formed without having to form a large mounting hole as in the prior art in a game board. And it can be easily attached without damaging the strength of the game board.
