  In order to give a player a high sense of expectation by the light emission effect of the illumination type push button device, it is preferable that the light emitted from the illumination type push button device is brilliant. Therefore, conventionally, a high-intensity LED (light emitting diode) has been used as a light source incorporated in an illuminated pushbutton switch. However, an illuminated pushbutton device using a high-brightness LED has a problem that power consumption increases.

  The present invention has been made in view of the above problems, and an object thereof is to provide a gaming machine including an illuminated pushbutton device capable of radiating radiant light without using a high-brightness LED. To do.

  In order to solve the above-described problems, the present invention is a gaming machine provided with an illumination type push button device, and the illumination type push button device includes a light source part, a lens having an emission surface on the front side and an incidence surface on the back side. One or more parts are formed, and includes an optical member that makes light emitted from the light source part incident from the incident surface and emits the incident light outward from the emission surface, A single convex portion that is convex in the light exit direction is formed on the exit surfaces of the two lens portions, and the light entrance direction of one lens portion of the optical member is opposite to the light entrance direction. A plurality of convex portions that are smaller than the convex portion of the light exit surface are formed.

  According to the shape of the entrance surface of the lens unit and the shape of the exit surface in the present invention, light incident on the lens unit from the entrance surface is condensed on the exit surface by a plurality of convex portions of the entrance surface, and exit surface The light condensed on the light diffuses toward the outside. As described above, since the once condensed light is diffused in the lens portion, there is an effect that the irradiation light can be brightened even with a low luminance light source without using a high luminance light source.

  In the gaming machine of the present invention, it is preferable that both the convex portion of the emission surface and the convex portion of the incident surface have a spherical shape.

  Thereby, the effect that the condensing function in an entrance plane and the light-diffusion function in an output surface can be made higher is produced.

  Furthermore, the gaming machine of the present invention has a light guide member that guides light emitted from the light source unit in addition to the above configuration, and the light guide member includes an incident surface of the lens unit. A standing portion extending toward the surface is formed, and the end portion faces the incident surface of the lens portion and has an end surface that emits light to the incident surface, and the end surface faces the end surface. The structure narrower than the said entrance plane may be sufficient.

  According to this configuration, the light emitted from the end surface of the light guide member can be diffused over the entire incident surface, and the light emitted from the end surface leaks without entering the incident surface. The amount of light can be suppressed. Therefore, it is possible to effectively use the light emitted from the light source unit and incident on the light guide member, and there is an effect that the irradiation light can be more glamorous even with a low-intensity light source.

  According to the illumination type push button device provided in the gaming machine of the present invention, there is an effect that the irradiation light can be brightened with a low luminance light source without using a high luminance light source.

And a columnar standing portion 106b extending in the B direction.

  A recess for forming a sealed space between the light source substrate 105 and the incident portion 106a is formed on the light source substrate 105 side (A direction side) of the incident portion 106a. The incident portion 106 a is mounted on the light source substrate 105 so that the three LED elements 205 a of the first light source portion 205 are positioned between the concave portion of the incident portion 106 a and the light source substrate 105. As a result, as shown in FIG. 4, the LED element 205a of the first light source unit 205 is sealed by the light source substrate 105 and the incident unit 106a. Note that there is a single sealed space formed between the light source substrate 105 and the incident part 106a, and the three LED elements 205a of the first light source part 205 are arranged in the same sealed space.

  Further, as shown in FIG. 4, in the incident portion 106a, a projection T protruding toward the LED element 205a is formed on the surface of the LED element 205a. Further, the same number of protrusions T as the LED elements 205a are formed.

It is a columnar part having the same character shape. The upright portions 106 b are formed in the same number as the LED elements 205 a included in the first light source portion 205. Specifically, in FIG. 3, in order from the left side, an upright portion 106b showing the shape of “X”, an upright portion 106b showing the shape of “Y”, and an upright portion 106b showing the shape of “Z” Are lined up.

  Next, the relationship between the LED element 205a of the first light source unit 205 and the standing portion 106b of the first light guide member 106 will be described in detail. In the push button device 10, as shown in FIG. 4, one LED element 205a, one protrusion T, and one standing portion 106b are arranged in the B direction. That is, for each LED element 205a, one protrusion T and one standing portion 106b are provided at a position in the B direction from the LED element 205a.

  As shown in FIG. 4, the LED element 205a faces the protrusion T located in the direction from the LED element 205a toward the B direction, but the surface of the protrusion T facing the LED element 205a is It becomes an incident surface on which the light of the LED element 205a is incident. The light incident from the incident surface is guided straight in the B direction by the standing portion 106b located in the direction from the incident surface in the B direction, and is an end surface on the B direction side of the standing portion 106b. The light exits from the exit surface M.

  As a result, for the user viewing the push button device 10 from the B direction side toward the A direction side, as shown in FIG. 2A, light is emitted from the emission surface M of the standing portion 106b having the shape of “XYZ”. The shape of “XYZ” can be clearly recognized.

  In the present embodiment, the exit surface M shown in FIG. 2A and FIG. Thereby, since the light emitted from the output surface M can be diffused, the character-shaped output surface M can be made more conspicuous to the user.

  Next, the diffusion lens 107 will be described. As shown in FIGS. 3 and 4, the diffusing lens 107 is a dome shape having a convex surface and a concave back surface, and is a transparent optical member that diffuses and emits light incident from the back surface.

  The diffusion lens 107 is mounted on the light source substrate 105 such that the concave back surface faces the LED element mounting side of the light source substrate 105. That is, in the diffusing lens 107, the surface on the A direction side is a concave back surface, and the surface on the B direction side is a convex surface.

  Further, since the diffusing lens 107 is a dome shape in which the surface on the A direction side is concave and the surface on the B direction side is convex, the end on the A direction side is a circular edge as shown in FIG. ing. A diffusion lens 107 is mounted on the light source substrate 105 so that the circular edge and the light source substrate 105 are in close contact with each other. As shown in FIG. 4, the circular edge of the diffusion lens 107 is positioned closer to the center of the light source substrate 105 than the LED elements 405 a of the third light source unit 405 in the light source substrate 105, and The LED elements 205 a of the first light source unit 205 and the LED elements 305 a of the second light source unit 305 are positioned on the outer peripheral side of the light source substrate 105.

  Further, as shown in FIG. 3, the diffusion lens 107 is formed with a through hole 107 a penetrating from the back surface side to the front surface side. The outline of the through-hole 107a has the same character shape as the cross-section of the standing portion 106b of the first light guide member 106 and the character shape of the exit surface M, and stands so that the standing portion 106b is fitted with play. The area is slightly larger than the cross section of the installation portion 106b.

  As shown in FIG. 4, the first light guide member 106 has an incident portion 106 a that covers each LED element 205 a of the first light source portion 205, and a standing portion 106 b that is fitted in the through hole 107 a. It is mounted on the substrate 105. Note that the standing portion 106b of the first light guide member 106 is not adhered to the diffusion lens 107 with an adhesive or the like, and has a play with the diffusion lens 107, and is inserted into the through hole 107a of the diffusion lens 107. Fitted.

  Further, as shown in FIG. 4, the diffusion lens 107 is located in the direction from the LED element 305 a of the second light source unit 305 toward the B direction, and the LED element 305 a and the back surface of the diffusion lens 107 face each other. Yes. As a result, light emitted from the LED element 305 a of the second light source unit 305 enters the diffusion lens 107 from the back surface of the diffusion lens 107 and is diffused from the surface of the diffusion lens 107. In addition, even if the light from the second light source unit 305 is irradiated on the wall surface of the first light guide member 106, the light is totally reflected by the first light guide member 106, so that the light incident on the first light guide member 106 is prevented. It is like that.

  Next, the light shielding plate 108 will be described. The light shielding plate 108 is a hollow cylindrical member, and is a light reflecting member whose outer peripheral surface and inner peripheral surface are mirror surfaces.

  As shown in FIGS. 3 and 4, the light shielding plate 108 is attached between the diffusing lens 107 and the second light guide member 109.

  As a result, the light emitted from the first light source unit 205 and the second light source unit 305 located on the inner peripheral side of the light shielding plate 108 travels on the outer peripheral side of the light shielding plate 108 (the third light source unit 405 has a light path). Light leakage from the third light source unit 405 positioned on the outer peripheral side of the light shielding plate 108 and light emitted from the third light source unit 405 traveling on the inner peripheral side of the light shielding plate 108 (first optical path). Leakage into the light path of the light source unit 205 and the second light source unit 305 is suppressed. For example, as shown in FIG. 4, even if light emitted from the LED element 305a of the second light source unit 305 and diffused by the diffusion lens 107 is directed toward the second light guide member 109, the second light guide Instead of reaching the optical member 109, it is reflected by the light shielding plate 108 and is directed toward the B direction.

  Next, the second light guide member 109 will be described. The second light guide member 109 is an optical member made of a material that totally reflects light (for example, acrylic resin) and having transparency. The second light guide member 109 is mounted on the light source substrate 105 so as to be positioned on the B direction side of the LED element 405 a of the third light source unit 405. As a result, as shown in FIG. 4, the LED element 405 a of the third light source unit 405 is disposed between the light source substrate 105 and the second light guide member 109.

  As shown in FIGS. 3 and 4, the second light guide member 109 is formed on the side of the A direction and has a ring-shaped incident part 109a facing the LED element 405a of the third light source part 405, and the incident part 109a.

Yes. The protrusion 109 c functions as a support column that supports the second light guide member 109 on the light source substrate 105. That is, when the protrusion 109c is in close contact with the light source substrate 105, a space is formed between the portion of the incident portion 109a of the second light guide member 109 facing the LED element 405a and the light source substrate 105. The second light guide member 109 is mounted on the light source substrate 105. That is, as shown in FIG. 4, the LED element 405 a of the third light source unit 405 is disposed in the space between the incident part 109 a of the second light guide member 109 and the light source substrate 105.

  As shown in FIGS. 3 and 4, the standing portion 109 b of the second light guide member 109 extends from the incident portion 109 a in the B direction, and an end surface on the B direction side is an emission surface R (see FIG. 5). It is a columnar part. The upright portions 109b are formed in the same number as the LED elements 405a. Specifically, as shown in FIG. 3, standing portions 109b are arranged at equal intervals along the outer periphery of the incident portion 109a on the B direction side of the incident portion 109a. For each LED element 405a, one standing portion 109b is disposed at a position in the B direction from the LED element 405a.

  Next, the double lens array 110 will be described. The double lens array 110 is a cylindrical optical member having a top surface formed on the B direction side (no bottom surface is formed on the A direction side), and is made of a transparent acrylic resin. The end of the double lens array 110 on the A direction side is fixed to the light source substrate 105 and the base member 104. 3 and 4, the first light guide member 106, the diffusion lens 107, the light shielding plate 108, and the second light guide member are provided between the light source substrate 105 and the upper surface of the double lens array 110. 109 is arranged.

  As shown in FIG. 3, the same number of lens portions 110 a as the standing portions 109 b are formed on the upper surface of the double lens array 110. The lens portions 110a are arranged at equal intervals along the outer periphery of the upper surface of the double lens array 110.

  As shown in FIG. 5, the lens part 110a is a light diffusing part that diffuses and emits incident light. In the lens unit 110a, the B direction side is the exit surface S, and the A direction side is the entrance surface N. The exit surface S is the surface of the lens portion 110a, and the entrance surface N is formed on the back side of the exit surface S and forms the back surface of the lens portion 110a.

  As shown in FIGS. 4 and 5, the exit surface S of one lens portion 110a is a single spherical surface convex in the light exit direction (B direction). On the other hand, the incident surface N of one lens portion 110a has a form in which a plurality of convex spherical surfaces (spherical surfaces smaller than the spherical surface of the exit surface N) are formed in the direction opposite to the light incident direction (A direction). is there.

  As shown in FIG. 5, for each LED element 405a, one standing portion 109b and one lens portion 110a are provided at a position in the B direction from the LED element 405a, and the standing portion 109b.

The exit surface R of the upright portion 109b is designed to be narrower than the entrance surface N facing the exit surface R on the B direction side of the exit surface R.

  And as FIG. 4 shows, the light emitted from LED element 405a injects into the 2nd light guide member 109 from the incident part 109a of the 2nd light guide member 109, and to the B direction side of the said LED element 405a The light is straightly guided in the B direction by the standing portion 109b positioned, emitted from the emission surface R of the standing portion 109b, and the lens portion 110a from the incident surface N of the lens portion 110a located on the B direction side of the LED element 405a. Is incident on. Furthermore, the light incident on the lens unit 110a is collected on the exit surface S by the plurality of spherical surfaces of the entrance surface N, and the light collected on the exit surface S is diffused outward. Thus, since the light once condensed in the lens part 110a is diffused, the light diffused from the lens part 110a becomes gorgeous.

  As shown in FIG. 3, a through hole 110 b that penetrates from the A direction side to the B direction side is formed on the upper surface of the double lens array 110. The outline of the through hole 110b has the same shape as the outline of the through hole 107a. That is, the outline of the through hole 110b has the same character shape as the cross section of the standing portion 106b of the first light guide member 106 and the character shape of the emission surface M so that the standing portion 106b is fitted with play. Further, the area is slightly larger than the cross section of the standing portion 106b. And as FIG. 4 shows, the standing part 106b of the 1st light guide member 106 so that the output surface M of the standing part 106b of the 1st light guide member 106 may protrude in the B direction side from the through-hole 110b. Is fitted in the through hole 110b. The standing portion 106b of the first light guide member 106 does not adhere to the double lens array 110 with an adhesive or the like, and has a play between the double lens array 110 and the penetrating portion 106b. It fits into the hole 110b.

  4, the upper surface of the cover 111 and the exit surface S of the lens portion 110a on the upper surface of the double lens array 110 face each other, and the upper surface of the cover 111 and the exit surface M of the first light guide member 106 are in contact with each other. The cover 111 is fixed to the case 101 so as to face each other. Thus, the first light guide member 106, the diffusion lens 107, the light shielding plate 108, the second light guide member 109, and the double lens array 110 are disposed between the upper surface of the cover 111 and the light source substrate 105. Become.

  According to the above configuration, as shown in FIG. 4, the light from the LED element 205 a (first light source unit 205) does not pass through the diffusing lens 107 and the double lens array 110, but the first light guide member 106 performs the B direction. The first light guide member 106 emits light from the exit surface M on the B direction side of the double lens array 110, passes through the cover 111, and is emitted to the outside. The light from the LED element 305a (second light source unit 305) is diffused by the diffusing lens 107, and then passes through the cover 111 and is emitted to the outside. Further, the light from the LED element 405a (third light source unit 405) is guided in the B direction by the second light guide member 109 and is once condensed by the lens unit 110a (see FIG. 5) of the double lens array 110. Then, the light is diffused and passed through the cover 111 to be released to the outside.

[About Double Lens Array 110]
Hereinafter, advantages of the double lens array 110 will be described. As described above, the push button device 10 of this embodiment includes the third light source unit 405 and the double lens array 110. As shown in FIGS. 4 and 5, the double lens array 110 is formed with one or more lens portions 110 a each having a front-side exit surface S and a back-side entrance surface N, and is emitted from the third light source portion 405. The incident light is incident from the incident surface N, and the incident light is emitted from the emission surface S to the outside. In addition, a single spherical surface that is convex in the light exit direction is formed on the exit surface S of one lens unit 110a, and what is the light entrance direction on the entrance surface N of one lens unit 110a. In this configuration, a plurality of spherical surfaces that are reverse convex portions and smaller than the spherical surface of the exit surface S are formed.

  According to such a configuration, as shown in FIG. 4 and FIG. 5, the light incident on the lens unit 110 a from the incident surface N is condensed on the output surface S by the plurality of spherical surfaces of the incident surface N, and the output surface S The light condensed on the light diffuses toward the outside. In this way, since the light once condensed by the lens unit 110a is diffused, the light emitted from the lens unit 110a can be gleaned even with a low-luminance light source without using a high-luminance light source.

  The exit surface S of the lens portion 110a is not limited to a spherical shape as long as it is convex in the light exit direction and diffuses light in the exit direction. For example, it has an aspheric shape. It may be. However, in order to enhance the light diffusion function on the exit surface S, it is preferable that the exit surface S has a spherical shape as in the present embodiment. In addition, the incident surface N of the lens portion 110a has a spherical shape as long as a plurality of convex portions that are convex in the light emitting direction are formed and the light is condensed in the incident direction. For example, the convex portion may be an aspherical shape. However, in order to enhance the light collecting function on the incident surface N, it is preferable that the convex portions formed on the incident surface N have a spherical shape as in the present embodiment.

  Further, as shown in FIGS. 3 to 5, the push button device 10 of the present embodiment includes a second light guide member 109 that guides and guides light emitted from the third light source unit 405. The light guide member 109 is formed with a standing portion 109b extending toward the incident surface N of the lens portion 110a. The 109b faces the incident surface N of the lens portion 110a and emits light to the incident surface N. It has an emission surface (end surface) R. The exit surface R of the standing portion 109b is narrower than the entrance surface N facing the exit surface R.

  According to this configuration, the light emitted from the exit surface R of 109b of the second light guide member 109 can be diffused over the entire entrance surface N, and the entrance surface N of the light exiting from the exit surface R of 109b. It is possible to suppress the amount of light that leaks without being incident on. Therefore, it is possible to effectively use the light emitted from the third light source unit 405 and incident on the second light guide member 109, and it is possible to produce more radiant light even with a low-intensity light source.

[About the first light guide member 106 and the diffusion lens 107]
Next, advantages of the first light guide member 106 and the diffusion lens 107 will be described. As described above, the push button device 10 of the present embodiment includes the light source substrate 105, the first light source unit 205 and the second light source unit 305, the first light guide member 106, and the diffusing lens 107.

  The diffusing lens 107 has a dome shape with a convex surface and a concave back surface, and is arranged so that the back surface faces the light source substrate 105. The first light source unit 205 and the second light source unit 305 are mounted on the side of the light source substrate 105 facing the diffusion lens 107. The first light guide member 106 is fitted in a through hole 107 a formed in the diffusion lens 107 so as to penetrate from the back surface side to the front surface side of the diffusion lens 107, and the one light source member 106 covers the first light source unit 205. It is mounted on the substrate 105 and the other end protrudes from the diffusion lens 107 in the B direction (direction from the back surface to the front surface of the diffusion lens 107).

  The light from the second light source unit 305 enters the diffusing lens 107 from the back surface of the diffusing lens 107 and is diffused from the surface of the diffusing lens 107 so as to be irradiated to the outside. On the other hand, the light from the first light source unit 205 is incident on the first light guide member 106 from the incident unit 106a facing the first light source unit 205 on one end side of the first light guide member 106. The light guide member 106 is guided inside and emitted from the end surface (exit surface M) on the other end side of the first light guide member 106, so that the light is emitted to the outside.

  According to the above configuration, the light from the second light source unit 305 is diffused and emitted from the surface of the diffusing lens 107, and the light from the first light source unit 205 is guided to the first light guide member 106. Then, the light is emitted from the light exit surface R of the first light guide member 106 to be irradiated to the outside.

Furthermore, according to the above configuration, since the first light source unit 205 is covered with the light source substrate 105 and the first light guide member 106, the light from the first light source unit 205 is transmitted to the first light guide member 106. Leaking from between the light source substrate 105 and the light source substrate 105, and the situation where the light from the first light source unit 205 is mixed with the light emitted from the second light source unit 305 and reaching the diffusion lens 107 can be suppressed. Moreover, since it can also suppress that the light emitted from the 2nd light source part 305 enters between the 1st light guide member 106 and the board | substrate 105 for light sources, it is from the 1st light source part 205 to the 1st light guide member 106. The situation where the light of the 2nd light source part 305 is mixed with the incident light can be suppressed. Thus, since it can suppress that the light of the 1st light source part 205 and the light of the 2nd light source part 305 are mixed, for the person who looks at the pushbutton apparatus 10, from the 1st light source part 205 among the pushbutton apparatuses 10, it is. There is an effect that it is possible to clearly distinguish the region irradiated with the light from the region irradiated with the light from the second light source unit 305. Thereby, by making the end surface (exit surface M) on the B direction side of the first light guide member 106 into a predetermined shape (character shape in the present embodiment), the predetermined shape can be clearly shown to the user. Have
For example, the light of the pair of LED elements 305a of the second light source unit 305 are all the same color, and the color of the light of the three LED elements 305a of the first light source unit 205 is the color of the light of the LED elements 305a of the second light source unit 305. You can make it different. Thereby, the color of the light emitted from the emission surface M having a predetermined shape of the first light guide member 106 is different from the color of the light diffused by the diffusion lens 107 around the first light guide member 106. Thus, the user can clearly recognize the predetermined shape. The light colors of the three LED elements 305a are the same as long as the light colors of the three LED elements 305a of the first light source unit 205 are different from the light colors of the LED elements 305a of the second light source unit 305. However, they may be different from each other. Further, the predetermined shape may be a character shape, a decorative shape other than a character (such as a star), a contour of a character employed in the pachinko machine 1, or the like. However, in the present embodiment, the predetermined shape is a character shape. Specifically, the first light guide member 106 of the present embodiment is formed on one end side (A direction side), and includes an incident portion 106a that covers the LED element 205a of the first light source portion 205, and the incident portion 106a to the first light guide member 106. The light guide member 106 has a columnar standing portion 106b extending toward the other end side (B direction side), and the other end side (B direction side) end portion of the standing portion 106b emits light. It is the surface M, and the cross section of the standing part 106b and the output surface M are the same character shape. Thereby, the said character shape can be made to stand out by emitting the light of the 1st light source part 205 from the character-shaped emission surface.

  Further, according to the configuration of the present embodiment, as described above, the second light source is provided in the optical path of the first light source unit 205 without attaching a light shielding plate between the first light source unit 205 and the second light source unit 305. Since the light from the first light source unit 205 can be prevented from leaking into the optical path of the second light source unit 305 and the light from the unit 305 can be suppressed, the number of parts can be reduced compared to the configuration of Patent Document 1 (Japanese Patent Laid-Open No. 2010-33860) There is an effect that it can be reduced.

  Further, the exit surface M of the first light guide member 106 of the present embodiment is subjected to a texture process. Since the embossed exit surface has an effect of diffusing light, the character-shaped exit surface M can be more conspicuous to the user.

  In the present embodiment, the standing portion 106 b of the first light guide member 106 is not bonded to the diffusion lens 107 and the double lens array 110, and the through hole 107 a of the diffusion lens 107 and the double lens array 110 are not bonded. It is fitted in the through hole. In other words, the standing portion 106 b is fitted in the through hole of the diffusion lens 107 and the through hole of the double lens array 110 in a state having play with respect to the diffusion lens 107 and the double lens array 110. As described above, if the standing portion 106 b is simply fitted to the diffuser lens 107 and the double lens array 110 without being bonded, the light emitted from the second light source portion 305 enters the first light guide member 106. Can be further suppressed. The reason is as follows. Temporarily, in the through hole 110a of the double lens array 110, the standing part 106b and the double lens array 110 are bonded with an adhesive, or in the through hole 107a of the diffusion lens 107, the standing part 106b and the diffusion lens 107 are bonded with an adhesive. When bonded, there may occur a situation where light emitted from the second light source unit 305 enters the first light guide member 106 through an adhesive layer formed of an adhesive. This is because nothing happens.
