  Hereinafter, the light guide member 2 of the decorative device 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 9. The present embodiment is disposed in a predetermined area in the gaming area of the gaming machine, for example, a predetermined area of the gaming board (e.g., the left end area avoiding the center role), and enhances the game effect by the electric decoration effect as the game progresses. The example of the decoration apparatus 1 is mentioned and demonstrated.

The decoration device 1 is provided with a light guide member 2 having a first surface 2a, a second surface 2b, a side surface 2c , and a light guide passage 4 as shown in FIGS. Be placed. The first surface 2a faces the front of the gaming machine, and the second surface 2b faces the rear of the gaming machine. The surface area of the first surface 2a and the second surface 2b is larger than the surface area of the side surface 2c. The light guiding member 2 has a light introducing surface 2d for introducing the light emitted from the LED 3 into the light guiding passage 4 in a predetermined direction X of the plate surface (here, a direction parallel to the horizontal plane passing the center of the plate) . An end face 5 provided as a part and continuous with the light introducing face 2 d and provided on the first face 2 a of the light guide member 2 and reflecting the guided light toward the predetermined direction X at a predetermined angle; A plurality of refracting surfaces which are provided on the first surface 2a of the light guide path 4 with a predetermined thickness, and which are reflected by the end surface 5 and refracted by the second surface 2b and radiate the light to the outside of the first surface 2a 6 and.

An end surface 5 and a plurality of refracting surfaces 6 are formed on the first surface 2 a, and a recess 9 is provided between the end surface 5 and the refracting surface 6 and between the plurality of refracting surfaces 6. The light introduced and reaching the end face 5 is once reflected by the end face 5 and further reflected by the second face 2 b and then can be refracted by the refracting face 6 to enhance the ability of the light to reach far, decoration The effect is higher.

The recess 9 has a curved surface. The bottom surface of at least one recess 9 located on the side far from the LED 3 in the recess 9 with respect to the predetermined direction X is a second surface 2 b from the second surface 2 b along the thickness direction of the light guide member 2 perpendicular to the predetermined direction X a direction toward the first surface 2a and the Y direction, when measuring the height from the second surface 2b to the bottom surface of the recess portion in the Y direction, closest to the LED3 the bottom surface of the recess 9 which is located on the side (here closer to LED3 It is set equal to or higher than the height of the position). That is, the thickness of the light guide passage in the at least one recess 9 located far from the LED 3 with respect to the predetermined direction X is the recess 9 located closer to the LED 3 (here, the location closest to the LED 3) The thickness is set to be equal to or thicker than the thickness of the light guide path in The normal direction Y is a direction orthogonal to the X direction. Although a specific reference surface of height can be variously taken, an example here is the second surface 2b parallel to the predetermined direction X. The height may be determined by measuring the height using either the average value of the predetermined range in the contour direction of the recess 9 or the lowest value (for example, specified by the tangent direction). . By projecting the three-dimensional curved surface of the recess 9 on a two-dimensional plane, the recess 9 may be converted into a two-dimensional diagram, and the height may be determined by comparing the diagrams. For example, it is possible to project the concave portion 9 in the X direction from the light introducing surface 2d to the opposite side surface 2c, create a two-dimensional projection map, and judge the height by comparing the diagrams. It is.

In FIG. 7, the thickness of the light guiding passage 4 in the leftmost recess 9 in the drawing is the same as the thickness of the light guiding passage in the middle recess 9 in the drawing, of the light guiding passage 4 in the rightmost recess 9 in the drawing. thickness than the thickness of the light guide passage 4 in the recess 9 of the leftmost in FIG., the minute height difference [delta], is thicker. Although the concave portion 9 is a generally flat surface, the vertical cross section may be a curved surface having a downward convex shape. Although the case where the thickness (Y direction) of the light guide passage 4 in the region of the end face 5 is thicker than the thickness of the light guide passage 4 in the region of the refracting surface 6 is illustrated in FIG. The same applies to the case where the thickness of the passage 4 is thinner than the thickness of the light guiding passage 4 in the area of the refractive surface 6.

The thickness of the light guide passage 4 in the recess 9 may take various aspects. (1) A pattern in which the thickness of the light guide passage 4 in all the recesses 9 is the same, (2) a recess 9 in which the thickness of the light guide passage 4 in the recess 9 is the same , and the thickness is thicker recess 9, and the pattern are mixed, the thickness of the same recess 9 of the light guide passage 4 in (3) recesses 9, from the light guide passage thickness is thin recess 9 of 4 it coexist (4) A recess 9 having the same thickness as the light guide passage 4 in the recess 9, a recess 9 having a thicker light guide passage 4 and a recess having a thinner light guide passage 4 than them There is a pattern in which nines are mixed. (3) As in the case of (4), there is no problem as long as at least one thin concave portion 9 having a thickness of the light guide passage 4 in the concave portion 9 locally does not affect the whole.

  The refracting surface 6 is formed on a curved surface of a convex portion whose thickness is provided in the normal direction Y in the first surface 2a. The refractive surface 6 gradually increases in height (e.g., monotonically increases) and gradually decreases (e.g., monotonically decreases) in the X direction. The refracting surface 6 has a suitable upward convex curved surface. The refracting surface 6 is a surface having a continuous curved surface area having a predetermined area and a height. An end surface refracting surface 7 is formed in a portion adjacent to the recess 9 of the end surface 5. The refracting end face 7 gradually decreases (e.g., monotonically decreases) in height in the X direction. The aspect of increase / decrease of these heights can be changed suitably. The width of the illustrated recess 9 is an example, and can take a wide variety of forms (e.g., a linear form, a wide form).

  The refracting surface 6 is a curved surface, and the curvature of the region near the concave portion 9 is set larger than the curvature of the other regions. The refracting surface 6 has a hilly surface shape.

  At least a part of the refracting surface 6 is arranged at a position to decorate the character M. Also, the recess 9 can be a continuous line provided on all or part of the outline of the character M.

  The light guide member 2 is made of an acrylic resin excellent in light transmittance, and includes an area having a constant thickness and an uneven area over the entire length, and the first surface 2a corresponds to the area showing the outline of the character M Surface light emission (hereinafter referred to simply as contour surface light emission) to perform surface light emission, in which the refracting surface 6 and the concave portion 9 are formed in a concavo-convex shape on the first surface 2a corresponding to the contour of the character M It is done. The use of the two principles of refraction and reflection limits the degree of freedom in design, but because the refraction surface 6 uses the refraction principle, it produces unique light with a soft and soft texture. By providing the end surface refracting surface 7 on the end surface 5, light can be emitted from the surface also using the refraction principle.

In correspondence with the light inlet surface 2d provided as part of the side surface 2c of the light guide member 2, illuminations substrate 10 is arranged outside (left side in FIG. 3) of the side surface 2c, LED 3 light introduced in a predetermined direction X It is provided adjacent to the surface 2 d so as to emit light. The electric decoration substrate 10 is not provided on the side surface 2 c other than the light introducing surface 2 d. The illuminations substrate 13 to be described later as shown in FIG. 3 enhance the decorative effect by providing a part of the upper surface of the light guide member 2.

A plurality of LEDs 3 are arranged adjacent to each other on the electric decoration substrate 10 in a dot shape. The electric decoration substrate 10 is disposed in the vertical direction so as to face the light introducing surface 2 d. The width of the electric decoration substrate 10 is the same as or substantially the same as the light introducing surface 2 d. A light source other than the LED 3, for example, a lamp may be used. The width of the electric decoration substrate 10 is substantially the same as the thickness including the light guide member 2, the decoration sheet 11, and the back plate 12. The LED 3 is substantially the same as the light introducing surface 2 d.

The decorative sheet 11 having the character M on the front surface is laminated on the back surface of the light guide member 2. The decorative sheet 11 is preferably a printed film sheet of a design. The film sheet should have appropriate light transmittance. A back plate 12 is disposed to cover the second surface of the decorative sheet 11. A through hole 12a is formed in the upper part of the back plate 12, and the light emitting part 13a covering the through hole 12a on the second surface of the back plate 12 is provided with a light emitting portion 13a having an LED. The light decoration cover 14 is disposed on the second surface. The transparent aspect of the back plate 12 may be a light guide plate as a backlight in this embodiment. When performing a contour effect, it is preferable to adjust the brightness of the backlight to be dark. The light leaked from the light guide member 2 is produced with the feeling that the decoration sheet 11 is illuminated from the front. The light guide member 2, the back plate 12, the electric decoration substrate 13, and the electric decoration cover 14 are detachably connected by the connecting members 15, 16, 17, screws, screw holes, screws, screw holes or the like. The decorative sheet 11 is sandwiched between the light guide member 2 and the back plate 12.

  The light from the light emitting unit 13a passes through the through hole 12a and causes the local part of the character M, for example, the face to emit light.

  If the size of the LED 3 and the thickness of the plate become large, there is a risk that light may escape, but since the light guide member 2 is formed in a thin plate shape, reflection at the end face 5 is close to total reflection. Since the light does not escape from the end face 5 too much, the light decoration effect is enhanced. Since little light leaks to the outside at the end face 5, the light intensity as the light decoration is maintained.

  The decorative sheet 11 having the character M on the surface is disposed on the second surface 2 b of the light guide member 2, and the recess 9 is disposed at a position corresponding to the outline of the character M.

  The decorative sheet 11 is a film in which color is added to a pattern, and here, the pattern of a karate enthusiast (character M) is printed.

The effects of this embodiment will be described. As shown in FIG. 7, the light emitted from the LED travels in the X direction while being reflected by the light guide path 4, and the light is refracted by the refracting surface 6 and the end surface refracting surface 7. The thickness of the light guide passage 4 in at least one of the concave portions 9 located on the side far from the LED 3 with respect to the predetermined direction X (the concave portion 9 at the center and the rightmost in FIG. recesses 9 located closer to the side by because it is thick rather set from the same or the thickness of the light guide passage 4 in the (recess 9 of the drawings leftmost in FIG. 7), the predetermined direction of light is the light guide passage 4 In the course of traveling to X, the light is prevented from leaking to the outside, the limit for light to be extended is expanded, the light can be appropriately refracted, and the light efficiency is increased. Since the refracting surface 6 is formed on an upwardly convex curved surface corresponding to the pattern, contour surface light emission is performed on the side closer to the recess 9 based on the principle of refracting light emission. A very clear light can be avoided, and a smooth and soft three-dimensional decoration light, unique surface light emission such as so-called indirect lighting can be realized.

  While expressing decorative light rich in soft three-dimensional effect by contour surface light emission using refraction of light by the refracting surface 6 and the end surface refracting surface 7 in the first surface 2a, from regions other than the portion near the concave portion 9 of the refracting surface 6 The surface luminescence of the image represents the entire pattern and background. By superimposing these two types of surface light, it is possible to express a tasteful expression.

  Since the recess 9 is disposed at a position corresponding to the outline of the design of the decorative sheet 11 on which the character M is drawn, the function of the refracting surface 6 and the end surface refracting surface 7 in the portion near the recess 9 As a result, the refracted light makes the outline soft and soft, and the light expression by the outline surface light emission of the character M can be emphasized.

  The light from the light emitting unit 13a passes through the through holes 12a and causes the local part of the character M of the decorative sheet 11, for example, the face to emit light, whereby the preference is enhanced.

  A modification of the present embodiment will be described with reference to FIGS. About common composition and an effect, explanation of the above-mentioned embodiment is used and difference is mainly explained. In this modification, a recess 20 is formed on the second surface 2 b of the light guide member 2. The recess 20 is provided continuously in a part of the position corresponding to the recess 9. The recess 20 may be set so as to overlap a part of the outline of the character M, and can be formed in an area other than the character M. The recess 20 may be provided at a position corresponding to the entire contour of the character M, or may be provided at all the positions corresponding to the recess 9.

  The recess 20 is a flat groove, in this case, an inverted V-shaped cross section, and is set in a predetermined range so as to be continuous in the surface direction of the second surface 2b and to gradually reduce the distance between the inclined surfaces along the Y axis direction. It is done. Contour surface light emission on the front side rich in a soft three-dimensional effect utilizing refraction of light by the refracting surface 6 and the end surface refracting surface 7 in the first surface 2a, and the concave portion 20 of the second surface 2b provided along the contour Contour surface light emission on the back side using complex refraction and reflection of light (for example, light reflected by the recess 20 returns to the refracting surface 6, or light refracted by the recess 20 is temporarily emitted to the outside Light is reflected back to the refracting surface 6, etc., and total surface light emission from regions other than the refracting surface 6, the end surface refracting surface 7 and the recess 20 represents the entire pattern and background. By superimposing these three types of light, it is possible to express tastefulness.
