Description

  The present invention relates to a gaming machine having a light emitting device.

  A gaming machine such as a slot machine or a pachinko gaming machine has a light emitting device for production, for example, lighting and extinguishing of various colors can be performed. Such a light emitting device generally includes an LED board (light source board) on which a plurality of LEDs as light sources are mounted apart from each other, and covers the front side (player side) of the LED board away from the LED board. An outer lens visually recognized by a person, an LED substrate, and an inner lens disposed between the outer lens.

  The outer lens is a member that constitutes the outermost surface of the light emitting device, and is visually recognized by the player directly or through a transparent plate. This outer lens is composed of, for example, a picture or character indicating a character and its background, and the picture or character is often three-dimensionally shaped. In some cases, the outer lens forms an abstract pattern instead of a character.

  In a light-emitting device used for decoration or production of a gaming machine, it is generally desired that an outer lens appears to emit light in a planar shape. That is, when a plurality of LEDs on the LED substrate are turned on, the light of each LED does not appear to be substantially dotted via the outer lens and the inner lens, but the light of the LED is diffused by the inner lens. It is desired that the light appears to emit light in a planar shape.

  For example, as the inner lens as described above, the incident surface (surface facing the light source side) on which light is mainly incident is a flat surface, and the exit surface (outer lens (player)) side on which light is mainly emitted is directed. A diffusing plate has been proposed in which a large number of irregularities are irregularly provided on the surface) and scattered light is scattered in an irregular reflection state (see, for example, Patent Document 1). In addition, when an LED is used as a light source, it is difficult to completely prevent the LED from being seen as a bright spot through an outer lens or an inner lens. In addition, a light emitting device has been proposed in which the luminescent spot of the LED is part of the light effect by diffusing the remaining light (see Patent Document 2). In this case, for the diffusion of the light of the LED, an uneven shape having annular grooves and annular ridges alternately and concentrically arranged on the incident surface of the inner lens is used. The LED is arranged opposite to the central part of the concentric circle), and the light of the LED that passes through the central part of the concentric circles of the inner lens irregularities is seen as a bright spot.

  By the way, in the light emitting device for gaming machines, it is also considered to intentionally leave the LED bright spot as described above, and not only cause the outer lens to emit light in a planar manner, There is a need for a light emitting device that emits light that remains in the impression of the player. For example, there is a need for a light emitting device that shines like a surface in which cut glass beads having a plurality of cut surface flat surfaces are spread.

  Such glass beads appear to shine with reflected light, but some of the reflected light is reflected inside again after some of the irradiated light enters the inside of the glass beads. The light is emitted to the outside, and the light reflected from the surface and the light reflected from the inside are shimmering. On the other hand, a lens member such as the inner lens of the above-described light emitting device or the like mainly shines with transmitted light, and a cut shape different from a cut shape that shines with reflected light is required.

  The present invention has been made in view of the above circumstances, and a game including a light-emitting device using a lens member that allows light from a light source to pass therethrough and allows the light to shine with light emitted from flat surfaces having different directions. The purpose is to provide a machine.

In order to achieve the above object, a gaming machine of the present invention is a gaming machine including a light emitting device having a lens member that transmits light emitted from a light source,
The lens member includes an incident surface facing the light source side, and an exit surface facing the opposite side of the incident surface,
The emission surface is provided with a plurality of convex portions arranged on the outer peripheral surface having a plurality of convex flat surfaces,
The front end portion of the convex portion is provided with a concave portion having a plurality of concave flat surfaces on the inner peripheral surface.

According to such a configuration, the light emitted from the light source passes through the lens member and is emitted from the exit surface, but the projecting portion having a plurality of convex flat surfaces on the outer peripheral surface on the exit surface. Are formed side by side. In this case, it is considered that the flat surfaces forming one convex portion have different angles. Moreover, since the angle of the light emitted from each flat surface for convex portions is limited by the angle so that it can be transmitted through the refractive index, the flat surface for each convex portion constituting one convex portion. The light emitted from each of them is emitted in different angular ranges. Note that these angle ranges may overlap each other.
Also, the concave flat surface provided on the inner peripheral surface of the concave portion has a different angle between the concave flat surfaces constituting one concave portion, and the angle range of the emitted light is also different.

  Thereby, although the light from the light source is diffused and emitted, the angle range of the emitted light is different for each flat surface, so that it looks like a glittering state. That is, if the viewpoint is moved a little, the flat surface that emits light to the viewpoint side changes, and thus it looks more shining.

Further, for example, an outer lens constituting the surface layer of the light emitting device is disposed in the vicinity of the exit surface of the lens member. However, at a position close to the lens member, light emitted from the convex flat surface on the outer periphery of the convex portion. Is directed toward the outside of the convex portion, whereas the light emitted from the concave flat surface of the concave portion is directed toward the center of the concave portion. In this case, the angle range of light emission is different between the flat surface for the convex portion and the flat surface for the concave portion, and the light emitted from the flat surface for the convex portion is directed to the outside of the convex portion and is emitted from the flat surface for the concave portion. The light is directed toward the approximate center of the concave portion (convex portion) in the vicinity of the outside of the lens member, and is in a more sparkling state. Note that the convex portion whose surface is composed of the convex flat surface and the concave flat surface having different angles functions as a prism, which resolves the color of the light source from the difference in the refractive index depending on the wavelength of the light, making it more sparkling. It will be in the state.
From the above, the light in the glittering state is basically a state in which many lights having different directions are simultaneously generated within a certain range (area), and the light in each direction has a different color. By being in a state, the state that glitters is emphasized. In other words, the player sees the light of each LED through the lens member, but the light of each LED can be seen from at least a part of the above-described convex flat surface and concave flat surface. It seems that the light will be in a shining state, and by changing the appearance of the LED reliably with the convex flat surface on the outer peripheral side of the convex portion and the concave flat surface on the inner peripheral side of the concave portion, Can sparkle.

  The said structure of this invention WHEREIN: It is preferable that the said incident surface is provided with two or more concentric circle parts provided with the some cyclic | annular convex part arrange | positioned concentrically.

  According to such a configuration, light incident on the incident surface of the lens member from the light source is diffused by the concentric circular portions having a plurality of annular convex portions provided concentrically on the incident surface, and is directed toward the exit surface of the lens member. Since it is emitted from each flat surface of the emission surface as described above, it is possible to prevent brightening only in the vicinity of the LED, and to make the emission surface shine in a shining state over a wide range of the emission surface. In addition, each annular convex part differs in diameter, and it becomes an annular recessed part between the annular convex parts arrange | positioned concentrically.

  In the configuration of the present invention, the convex portion is provided with six substantially pentagonal flat surfaces for convex portions adjacent to each other around the front end portion of the convex portion, and the front end portion side protrudes. Preferably, the convex flat surface is inclined and provided in a hexagonal frustum shape, and the substantially triangular pyramid concave portion is provided at the tip portion surrounded by the convex flat surface.

  According to such a structure, each convex part consists of six substantially pentagonal flat surfaces and a triangular pyramid-shaped concave part at the center. The outer periphery of each convex part is composed of, for example, 12 sides including two sides of a flat surface of six substantially pentagons, and six convex parts are arranged around each convex part so that the plurality of convex parts are mutually connected. It can arrange | position so that it may adjoin. Further, the concave portion has a triangular pyramid shape, and light emitted from the flat surface for each concave portion is focused on the center side of the concave portion outside the front end side of the convex portion. For these reasons, as described above, the light transmitted through the light source can be in a shining state.

  As a result, the flat surface for the convex portion and the flat surface for the concave portion are arranged in a complicated manner but can be regularly arranged. Depending on the location, the flat surfaces with different angles may be arranged almost randomly. In this case, the light from the light source can be used efficiently to make it appear as if it is shining brightly. In addition, the substantially pentagon includes, for example, a polygon that is pentagonal or higher than a pentagon with a concave portion in a shape that does not have a concave portion.

  According to the present invention, the surface of the light emitting device is not made to shine almost uniformly in a planar shape, but it is possible to emit light from a plurality of surfaces with different angles to make it shine.

FIG. 4 shows the left light emitting device 60, and FIG. 5 shows the right light emitting device 60. These light emitting devices 60 represent characters as characters in a three-dimensional structure. The surface portion of the light emitting device 60 includes outer lenses 61 and 62 for the character portion and outer lenses 63, 64, 65, and 66 for the background of the character outside the character portion, and decorates the character portion. A decorative member 67.68 is provided. The outer lenses 61, 62, 63, 64, 65, 66 constitute the surface of the light emitting device 60. The outer lenses 61, 62, 63, 64, 65, 66 are directly exposed to the player in a state of being illuminated from the back side by a plurality of LEDs 69 (shown in FIG. 6). It is a part that is made visible. The outer lenses 61, 62, 63, 64, 65, and 66 are transparent or translucent members that are markedly colored. Here, the translucent member includes a member that has translucency but is difficult to see through the opposite side.

The left and right light emitting devices 60 have substantially the same configuration except that the shape of displayed characters is different. In the following description, the description of the right light emitting device 60 is omitted, and the left light emitting device 60 60 will be described.

FIG. 6 shows an exploded perspective view of the left light emitting device 60. The light emitting device 60 has a back cover 71 and LEDs from the back side (right side in the figure).
LED board (light source board) 72 having a plurality of 69 mounted thereon, inner lenses 74, 75, 76, 77 of the character background part covering the player side of the LED board 72, and inner lens (lens member of the character part) ) 73, a character portion outer lens 61, a character background outer lens 63, 64, and a character decoration member 67. Therefore, the inner lenses 73, 74, 75, 76, 77 are disposed between the LED substrate 72 and the outer lenses 61, 63, 64, and the light of each LED 69 on the LED substrate 72 is transmitted to the inner lenses 73, 74, 75, 76. , 77 is transmitted to the outer lenses 61, 63, 64, and the outer lenses 61, 63, 64 are illuminated toward the player.

  In the light emitting device 60, the light of the LED 69 on the LED substrate 72 is diffused in the character portion when passing through the inner lens 73 of the character portion, and further passes through the outer lens 61 to shine the outer lens. Similarly, the light of the LED 69 on the LED substrate 72 is diffused when passing through the inner lenses 74, 75, 76, 77 of the character background portion and further transmitted through the outer lenses 63, 64 in the character background portion. Make the outer lens glow.

  Therefore, in the character portion, the light of the LED 69 is diffused by the inner lens 73 and the entire outer lens 61 is made to shine. The inner lens 73 is shown in FIGS. 7 and 11 and has an incident surface 79 facing the LED substrate 72 side and the opposite surface, as shown in FIGS. 8 to 12, and facing the outer lens 61 and the player side. It is a plate-shaped member provided with the output surface 83.

  On the incident surface 79 of the inner lens 73, a concentric circular portion 80 in which a plurality of annular annular convex portions 81 are concentrically arranged to diffuse the light of each LED 69 of the LED substrate 72 is provided on the LED substrate 72. The same number as the number of LEDs 69 mounted on the portion covered with the inner lens 73 is provided. In one concentric circle portion 80, a plurality of annular convex portions having different diameters are arranged with their centers aligned. Also. Each annular convex part 81 arranged concentrically has an annular convex part 81 having a long diameter outside the annular convex part 81 having a short diameter in order of the diameter. Further, the pitch between the adjacent annular protrusions 81 (for example, the interval between the inner peripheral edges (outer peripheral edges) of the adjacent annular protrusions 81) is substantially uniform regardless of the length of the diameter of the annular protrusion 81. ing.

  Further, the concentric circular portion 80 is provided with a dome-shaped central convex portion 82 inside the annular convex portion 81 having the shortest diameter at the central portion. When the inner lens 73 and the LED substrate 72 are set so as to overlap the light emitting device 60, the position of the central convex portion 82 at the central portion of the concentric circular portion 80 when viewed from the player side (outer lens 61 side) The positions of the LEDs 69 coincide with each other. That is, when viewed from the player side, the central convex portion 82 of the concentric circular portion 80 and the LED 69 appear to overlap with each other, that is, the LED 69 is disposed at a position overlapping the rear side of the central convex portion 82. .

  Moreover, the diameter of the LED 69 may be close to the diameter of the central convex portion 82 and smaller than the outer shape of the smallest annular convex portion 81, for example. Further, as shown in FIG. 11, an annular recess 88 is formed between the annular projections 81. As shown in FIG. 11, the cross-sectional shape of the concentric circle 80 is close to that of a Fresnel lens. The concentric circular portion 80 diffuses the light of the LED 69. For example, the concentric circular portion 80 spreads from the LED 69 and reaches the inner lens 73 while setting the inclination angle of the light to the reference surface of the incident surface 79 of the inner lens 73 (the incident surface 79 is a flat surface). It may be made to approach 90 degrees with respect to the assumed surface.

  As shown in FIGS. 8 to 12, the exit surface 83 of the inner lens 73 has a convex portion 84 surrounded by a plurality of polygonal flat surfaces 90 for convex portions, and a concave portion 85 provided at the center portion thereof. Is provided. The convex portion 84 has a plurality of convex flat surfaces 90 arranged adjacent to each other in an annular shape, and the convex flat surface 90 is inclined so as to protrude from the outer peripheral edge side of the convex portion 84 toward the central portion. It is a thing.

The convex portion 84 has a truncated pyramid shape, and a concave portion 85 is formed on the top surface thereof. The flat surface 90 for convex parts is formed in polygonal shape, for example, the basic shape is a pentagon. The actual convex flat surface 90 includes a pentagonal shape and a hexagonal shape in which one side of the pentagon is recessed in a triangular shape.
Here, the basic shape of the convex portion 84 without the concave portion 85 is obtained by arranging six pentagonal flat surfaces in a ring shape and arranging six pentagons around one hexagon. Each of the six sides of the hexagon described above is one side of each of the six pentagons arranged around the hexagon. Further, among the sides of the pentagon, the sides adjacent to the left and right sides of the side that matches the above-described central hexagonal side match the sides of the pentagon adjacent to the left and right of the pentagon.

  Two sides on the outer peripheral side excluding the above three sides on the center side of the pentagon are adjacent to the adjacent convex portion 84. When the concave portion 85 is not provided, the inner peripheral side of the convex flat surface 90 arranged in an annular shape of the convex portion 84 is a hexagon having six sides, and the outer peripheral side is a dodecagon having twelve sides. Six convex portions 84 are arranged adjacent to each other around one convex portion 84, and the convex portions 84 are arranged side by side so that two adjacent sides coincide with each other. Two sides in contact with the adjacent one convex portion 84 are sides of different flat surfaces 90 for convex portions.

The concave portion 85 is provided at the central portion of each convex portion 84, and every other one of the six sides of the hexagonal top surface of the convex portion 84 in which the concave portion 85 is not provided as described above. The openings of the recesses 85 are formed by extending both end sides of the three sides. Here, when each side is extended, it is extended to the adjacent convex flat surface 90, so each extended side is not one side (straight line), It consists of 3 sides with 2 left and right extended sides. Since there are three of these three sides, the opening of the recess 85 is a hexagon.
Moreover, the shape of the recessed part 85 is a triangular pyramid shape from the three flat surfaces 91 for recessed parts. In this case, the convex flat surface 90 corresponding to every other extended side of the hexagonal top surface of the convex flat surface 90 of the convex portion 84 when the concave portion 85 is not provided. The flat surface 90 for a convex part corresponding to the side which becomes a pentagon and is recessed in the shape of a triangle without being extended becomes the flat surface of the above hexagon.

  The concave portion 85 is formed in a triangular pyramid shape including three concave flat surfaces 91. Each concave flat surface 91 has a pentagonal shape, and is a pentagonal shape having five sides from two sides forming a triangular pyramid and three sides forming a nine-corner opening.

  Each convex portion 84 has 12 sides on the outer periphery, and is joined to six convex portions 84 surrounding the circumference on two sides. Thereby, the convex part 84 is arrange | positioned along with the structure substantially the same as the honeycomb structure which has arrange | positioned six hexagons around the hexagon. Accordingly, one convex portion 84 including the concave portion 85 has nine flat surfaces from the six convex flat surfaces 90 and the three concave flat surfaces 91, and these convex portions 84 are formed on the output surface 83. Are regularly arranged in a honeycomb shape.

  In addition, each flat surface 90 for convex portions is arranged so as to emit light radially outside the convex portion 84, whereas each flat surface 91 for concave portions is formed of the convex portion 84 (the concave portion 85). It arrange | positions so that light may be radiate | emitted inside. Here, unlike the concentric circular portion 80 of the incident surface 79, the arrangement of the convex portions 84 having the respective concave portions 85 is not related to the arrangement of the LEDs 69 of the LED substrate 72. For example, as in the case of the concentric circular portion 80, the position of the central portion (concave portion 85) of the convex portion 84 and the position of the LED 69 are not overlapped. In addition, an adjustment recess 86 is provided on the output surface 83 side of the central convex portion 82 at the center of the concentric circular portion 80 of the incident surface 79 so that the central convex portion 82 and the inner lens 73 overlap each other. The adjustment concave portion 86 is provided in order to solve a problem caused by a thickening of the central convex portion 82 during molding of the inner lens 73 (for example, injection molding), for example, difficulty in filling the resin. It is a thing.

  In such a light-emitting device 60, in the inner lens 73 having an optical function for applying the light of the LED 69 to the outer lens 61 representing characters, the light of the transmitted LED is transmitted through the concentric circle portion 80 of the incident surface 79 as described above. Or the direction of light is brought close to a direction orthogonal to the reference plane of the inner lens 73. Further, when the light incident on the inner lens 73 from the incident surface 79 is emitted from the emission surface 83, the projections 84 are arranged so as to be regularly adjacent to each other as described above, and have the concave portions 85. Light is emitted from each of the convex flat surface 90 on the outer peripheral side and the concave flat surface 91 on the inner peripheral side.

  As a result, light is emitted from a large number of flat surfaces with different directions, for example, so that light is reflected in a state close to the reflected light when light is applied to the surface on which glass beads having a plurality of cut surfaces are spread. Can be transmitted. In particular, instead of regularly arranging the polyhedral projections, by using the projections 84 having the pyramid-like (for example, triangular pyramid) depressions 85, light is emitted to the respective projections 84 on the outer peripheral side. The above-mentioned glass beads are spread by having a plurality of surfaces with different angles (flat surfaces 90 for convex portions) and a plurality of surfaces with different angles (flat surfaces 91 for concave portions) that emit light on the inner peripheral side. A glittering state close to the reflected light from the surface can be realized by the transmitted light instead of the reflected light.

  In addition, the flat surface 90 for convex parts surrounding the outer periphery of the convex part 84 is not restricted to the combination of the above-mentioned hexagon and a pentagon, What is necessary is just polygonal shape. Moreover, the number of the flat surfaces 90 for convex parts arrange | positioned on the outer periphery of the convex part 84 is not restricted to six, It may be less than that or more. Further, the recess 85 is not limited to a triangular pyramid shape, and may be a pyramid shape of four or more squares.
