JP 2009-926 A

  However, since the configuration of Patent Document 1 is a configuration in which only light from a plurality of light emitting elements disposed on the lower side is reflected by the cylindrical member 2 and projected onto the screen, there is a risk of monotonous light decoration. There is. Further, since each light from the light emitting elements arranged in a dispersed manner is reflected on the outer peripheral surface of the cylindrical member 2 and projected as it is onto the screen, there is a possibility that unevenness of the light may occur on the screen.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a light decoration device that is less likely to cause extreme light unevenness and that allows more complex light decoration.

The present invention comprises an inner lens having light transparency and rotatable about a predetermined rotation axis;
An outer lens having light permeability, arranged at a predetermined interval on the outer side in the rotational radius direction of the inner lens, and rotatable about a predetermined rotation axis;
A drive source for rotating the inner lens and the outer lens integrally or independently;
A diffusing member disposed at a position away from the outer lens on the outer side in the rotational radius direction of the outer lens;
First light emitting means for irradiating light toward the inner lens;
Second light emitting means for irradiating light toward the outer lens;
Have
When the direction of the rotation axis of the inner lens is the vertical direction, and the predetermined direction orthogonal to the rotation axis is the front-rear direction,
The first light emitting means is arranged above or below the inner lens and irradiates light that passes through the inner lens along the vertical direction.
The second light emitting means is arranged behind the outer lens so as to face the peripheral wall portion of the outer lens and irradiates light on the front side so as to pass through the outer lens and the inner lens. ,
The light emitted from the first light emitting means toward the inner lens and the light emitted from the second light emitting means toward the outer lens are diffused at least within a predetermined range in the circumferential direction of the outer lens. It is the structure which is irradiated outside through a member.

  In the present invention, there are provided an inner lens and an outer lens having light transmissibility that can rotate about a predetermined rotation axis, light is emitted toward the inner lens by the first light emitting means, and the outer lens is irradiated by the second light emitting means. It is the structure which irradiates light toward a lens. Thus, since two types of lenses are provided inside and outside and light is applied to each lens by separate light emitting means, different decoration modes can be generated between the inner lens and the outer lens. In particular, since different types of light from each lens are radiated to the outside while diffusing through a predetermined region (within a predetermined range in the circumferential direction) of the diffusing member in this way, two types of light are emitted within this predetermined range A more complex light that is mixed with each other will be generated.

  Further, in the present invention, one end side in the axial direction of the inner lens is divided into a plurality of parts, and the divided surface portions are disposed so as to surround the rotation axis of the inner lens, and at least the axial direction of the adjacent divided surface portions is the axial direction. The height may be different, and the split surface portion may be irradiated with light from the first light emitting means according to the rotation of the inner lens. In this configuration, light from the first light emitting unit is incident on each of the plurality of divided surface portions according to the rotation of the inner lens. Therefore, on the inner lens side, reflected light or refracted light from the first light emitting means can be generated at different heights. That is, since there are a plurality of dividing surfaces having different heights (outer surfaces of the dividing surface portions), a large number of positions where light is diffused or bent can be set, and the light emission modes can be diversified.

  In this case, for example, the plurality of dividing surface portions gradually increase or decrease as they progress in the circumferential direction within a range from a predetermined starting position in the circumferential direction around the rotation axis of the inner lens. It may be a spiral staircase. In this configuration, more divided surfaces (outer surfaces of the divided surface portions) having different heights can be generated on the upper surface portion of the inner lens, and more complicated display is possible.

  Further, in the present invention, a holding member that holds the second light emitting unit at least at a position outside the rotational radius of the outer lens is provided outside the outer lens, and the second light emitting unit includes the outer lens. Is disposed opposite to the outer peripheral surface of the outer lens in the radial direction of the outer lens, and is disposed so as to pass through the outer lens and irradiate the outer lens with light on the side opposite to the second light emitting means side. The holding member is formed with a pair of ribs protruding toward the peripheral wall portion of the outer lens at positions on both sides of the second light emitting means in the circumferential direction of the outer lens. It may be. In this configuration, it is possible to irradiate the peripheral wall portion of the outer lens with the light from the second light emitting means, and to generate decorative light on the opposite side so as to transmit the outer lens. In particular, since the pair of ribs are arranged on both sides in the width direction of the second light emitting means, the light from the second light emitting means can be more concentrated and irradiated on the outer lens side.

  In this case, for example, the inner surfaces of the pair of ribs on the second light emitting means side may be configured as white surfaces or mirror surfaces. According to this configuration, the light from the second light emitting means can be prevented from leaking sideways, and the light can be collected more on the outer lens side.

  Further, in the present invention, when the direction of the rotation axis of the inner lens is the vertical direction and the predetermined direction orthogonal to the rotation axis is the front-rear direction, the first light emitting means is disposed above or below the inner lens. And is configured to irradiate light that passes through the inner lens along the vertical direction, and the second light emitting means is disposed behind the outer lens and facing the peripheral wall portion of the outer lens. And it is good to have a structure which irradiates light to the front side so that the said outer lens and the said inner lens may permeate | transmit. By doing so, light from the first light-emitting means and the second light-emitting means whose directions are greatly different from each other are irradiated in the vicinity of the inner lens and the outer lens, and more complicated light is easily generated.

  In the present invention, the diffusing member is formed in a sheet shape at least partially arranged around the outer lens, and is a concave or convex line inclined with respect to the direction of the rotation axis of the outer lens. It is preferable that the shape portions are formed at predetermined intervals, and the linear portions are inclined so as to be in a lower position as they proceed in the rotation direction of the outer lens. By doing so, it is possible to change the incident position, incident height, and the like of the light to the linear portion according to the rotation of the outer lens, and it is easy to cause light fluctuation and gentle movement.

Moreover, such a linear part 5a is good to comprise by knurling etc., for example.

  In the light decoration device 1 configured as described above, the rotating body 3 rotates by driving the drive source 7 configured as a motor. At this time, light is irradiated from the second light source unit 12 toward the outer lens 30 on the front side, so that the light is reflected or refracted by a large number of irregularities formed on the outer lens 30. Light can be used to express how the flames burn. On the other hand, the light irradiated upward from the first light source unit 11 is applied to each divided upper surface portion 22a of the inner lens 20, and acts to shine at least the vicinity of each divided upper surface portion 22a. In this way, the vicinity of the divided upper surface portions 22a having different heights shines, and these divided upper surface portions 22a rotate in the circumferential direction as the rotating body 3 rotates, so that the divided upper surfaces having different heights. It can be expressed that the sparks rise by the portion 22a. According to the above-mentioned two aspects, it is possible to express how the real flame burns with melody.

  Further, the rotation of the rotating body 3 by the drive source 7 may be a constant rotation speed. For example, by changing the rotation speed, the momentum of the flame can be changed and displayed. Further, such a light decoration device 1 is provided on a frame body or a decoration accessory of a gaming machine such as a pachinko machine, and used as a notification decoration (indication of reliability) of the gaming machine by changing the momentum of the flame. Can do. For example, under certain conditions, the rotating body 3 is rotated at the first rotational speed, and under the second condition where notification decoration is to be performed, the rotating body 3 is rotated at a second rotational speed that is faster than this. The decoration which increases momentum at the time of decoration becomes possible, and the player's expectation can be further enhanced.

(Main effects of this configuration)
In this configuration, the rotating body 3 configured to be rotatable about a predetermined rotation axis A1 is provided with an inner lens 20 and an outer lens 30 having light transmission properties. In this configuration, the second light source unit 12 emits light toward the outer lens 30. Thus, since two types of lenses are provided inside and outside and light is applied to each lens by separate light emitting means, different decoration modes can be produced in the inner lens 20 and the outer lens 30. Since different types of light from each lens are diffused by the diffusion sheet 5 in this way, more complicated light can be generated.

  When the direction of the rotation axis A1 is the vertical direction, the upper surface portion 22 of the inner lens 20 is divided into a plurality of portions, and the divided upper surface portions 22a are disposed so as to surround the rotation axis A1, and at least a plurality of divided upper surfaces are arranged. The heights of the portions 22 a are different from each other, and the plurality of divided upper surface portions 22 a are rotated so as to sequentially pass through the light projecting path of the first light source unit 11 according to the rotation of the rotating body 3. In this structure, according to rotation of the rotary body 3, the light from the 1st light source part 11 injects into the some division | segmentation upper surface part 22a in order. Therefore, on the inner lens 20 side, reflected light or refracted light from the first light source unit 11 can be generated at different heights, and decorative light having different heights can be sequentially generated.

  Further, the plurality of divided upper surface portions 22a have, for example, a spiral staircase shape whose height increases or decreases in order as it advances in the circumferential direction around the rotation axis A1 within a range of one turn from a predetermined starting position. . For example, when the position of the divided upper surface portion 22a having the lowest height among the plurality of divided upper surface portions 22a is set as the starting point position, in the range of one round from the starting point position (the divided upper surface portion 22a having the lowest height), It has a spiral staircase shape whose height increases in order as it proceeds clockwise in the circumferential direction when viewed from above. In this configuration, more reflective surfaces or refracting surfaces having different heights can be generated on the upper surface portion 22 of the inner lens 20, and a more complicated display is possible.

  In addition, when the predetermined direction orthogonal to the rotation axis A1 of the rotator 3 is the front-rear direction and the direction orthogonal to the direction of the rotation axis A1 and the front-rear direction is the width direction, the second light source unit 12 is located behind the rotator 3. 2 is arranged to face the peripheral wall portion 32 of the outer lens 30 and to irradiate light to the front side so as to pass through the outer lens 30. A pair of ribs 13 and 14 which are convex along are arranged. In this configuration, the light from the second light source unit 12 can be applied to the peripheral wall portion 32 of the outer lens 30, and decorative light can be generated so as to transmit the outer lens 30. In particular, since the pair of ribs 13 and 14 are arranged on both sides in the width direction of the second light emitting means, the light from the second light emitting means can be concentrated and irradiated on the front side.

  And the inner surface by the side of the 2nd light source part 12 (2nd light emission means side) of a pair of ribs 13 and 14 is comprised as a white surface or a mirror surface. According to this configuration, the light from the second light emitting means can be prevented from leaking sideways, and the light can be collected more on the outer lens 30 side.

  Further, when the direction of the rotation axis A1 is the vertical direction and the predetermined direction orthogonal to the rotation axis A1 is the front-rear direction, the first light source unit 11 is disposed above or below the rotating body 3 and along the vertical direction. The second light source unit 12 is arranged to face the peripheral wall portion 32 of the outer lens 30 behind the rotating body 3, and the outer lens 30 and the inner lens. 20 is configured to irradiate the front side with light so as to pass through 20. By doing so, the light from the first light emitting means and the second light emitting means having greatly different directions is irradiated near the inner lens 20 and the outer lens 30, respectively, and more complicated light is generated in the rotating body 3. It becomes easy to let you.

  Further, the diffusion sheet 5 is configured as a diffusion sheet disposed at least partially around the rotating body 3, and the concave or convex linear portions 5a inclined with respect to the direction of the rotation axis A1 are arranged at predetermined intervals. The linear portion 5a is inclined so as to become a lower position as it proceeds in the rotation direction of the rotating body 3. By doing in this way, the incident position, incident height, etc. of the light to the linear part 5a can be changed according to rotation of the rotary body 3, and it becomes easy to produce the fluctuation of light and a gentle movement.
