Japanese Patent No. 5405376

In Patent Document 1, the light emitted from the light emitting body is reflected obliquely downward by the reflecting member (see FIG. 9 of Patent Document 1). Therefore, there is a possibility that the lower portion shines brighter than the upper portion of the light emitting device for a game machine, and the light emitting mode of the revolving light cannot be simulated very faithfully.

An object of the present invention is to provide a light emitting device for a game machine that can faithfully simulate the light emitting mode of a rotating light. In the following description of each component of the present invention, in order to facilitate understanding of the present invention, the reference numerals of the corresponding parts of the embodiments are described in parentheses, but each component of the present invention is described. It should not be construed as limited to the configuration of the corresponding parts indicated by the reference numerals of the embodiments.

In order to achieve the above object, the feature of the present invention is a reflector (10) having a portion curved so as to bulge toward the player or a portion curved so as to dent toward the side opposite to the player. A plurality of light emitters (D1 to D7) provided at positions separated from the curved portion of the reflector, and the plurality of light emitters are provided with each of the light emitters and emitted from the plurality of light emitters, respectively. A plurality of lenses (L1 to L7) that concentrate the light on the central portion of the surface of the curved portion of the reflector, and a cover that covers the front surface of the reflector and reflects a part of the light. A light emitting device for a game machine (1) including a cover (40) composed of a half mirror that transmits a part of the light, and a control device (50) that causes the plurality of light emitters to emit light in a predetermined order. ).

In this case, the light emitting body may be a light emitting diode.

Further, in this case, it is preferable that the electronic circuit board (20) on which the plurality of light emitters are mounted is provided, and the electronic circuit board is arranged outside the curved portion of the reflector.

Further, in this case, the plurality of light emitters are arranged on a predetermined curve (C) in the electronic circuit board, and the curvature of the curve is set to be smaller than the curvature of the curved portion of the reflector. It is good to have.

In the light emitting device for a game machine according to the present invention, the light emitted from the light emitting diode is opposite to the central portion (the portion most protruding toward the player side or the player) of the curved portion of the reflector by the lens portion. It is focused on the most recessed part to the side). Therefore, it seems that one light emitting body exists inside the light emitting device for the game machine. The light focused on the apex of the central portion is reflected at the apex, and a part (about half) of the light is transmitted through the cover. Further, the remaining portion (about half) of the light reflected at the apex is reflected by the rear surface of the cover, and further reflected by the reflector. In this way, the light emitted from the light emitting diode is repeatedly reflected between the cover and the reflector, and a part of the light is transmitted through the cover in the middle of the reflection. This makes the reflector appear to shine as a whole. Further, it seems that one substantially spherical illuminant exists inside the light emitting device for the game machine. Then, the light emitters are turned on in a predetermined order. According to this, it is possible to realize a light emitting mode in which a reflecting mirror is rotated around one light emitting body provided inside a light emitting device for a game machine. As described above, according to the light emitting device for a game machine according to the present invention, a rotating light can be faithfully simulated.

A light emitting device 1 for a game machine according to an embodiment of the present invention will be described. First, the outline of the pachinko machine PM as a game machine to which the light emitting device 1 for a game machine is applied will be described. As shown in FIG. 1, the pachinko machine PM is a substantially rectangular parallelepiped device extending in the vertical direction. In the following description, the height direction (vertical direction) of the pachinko machine PM is referred to as the vertical direction. Further, the width direction of the pachinko machine PM is called the left-right direction, and the depth direction of the pachinko machine PM is called the front-back direction.

As shown in the figure, the pachinko machine PM includes a game ball launcher BS, a game board PB, and the like. The game ball launching device BS launches game balls (not shown) one by one toward the game board PB. The game board PB is arranged above the game ball launcher BS. The game board PB is a substantially rectangular plate-shaped member extending in the vertical direction. The game board PB is arranged so as to face the player. That is, the plate thickness direction of the game board PB coincides with the front-rear direction.

For example, the light emitting device 1 for a game machine is attached to the upper part of the front surface of the game board PB. The light emitting device 1 for a game machine emits light at the time of winning, for example. As will be described below, the light emitting device 1 for a game machine simulates a light emitting mode of a rotating light.

Next, the configuration of the light emitting device 1 for a game machine will be described. As shown in FIG. 2, the light emitting device 1 for a game machine includes a reflector 10, an electronic circuit board 20, a condenser lens 30, a cover 40, and a control device 50.

As shown in FIGS. 3 and 4, the reflector 10 has a base portion 11 that is gently curved so that the central portion in the left-right direction thereof is located slightly forward of both end portions. The front surface of the base 11 is mirror-finished. In the front view of the reflector 10, the base 11 has a substantially isosceles trapezoidal shape (see FIG. 4). The upper side 11T of the base 11 is curved in a bow shape so that the central portion in the left-right direction thereof is located slightly above both end portions. The lower side 11B is substantially horizontal. Further, the left side 11L extends linearly downward and to the left from the left end of the upper side 11T. However, the left side 11L is bent to the left at its lower end. Further, the right side 11R extends linearly downward and to the right from the right end of the upper side 11T. However, the right side 11R is bent to the right at the lower end portion thereof. That is, both lower corners of the base 11 project slightly to the left and right. Further, the central portion 11C of the base portion 11 is curved so as to bulge (protrude) toward the player side (forward) when viewed from the peripheral portion thereof. Specifically, the surface of the central portion 11C corresponds to a part of a spheroid SP obtained by rotating an ellipse having an axis AX extending in the vertical direction around the axis AX (see FIG. 5). That is, the surface of the central portion 11C corresponds to the surface of the portion of the spheroid SP that is parallel to the axis AX and located in front of the plane S that intersects the spheroid SP. In the example of FIG. 5, the polar radius is longer than the equator radius, but the polar radius may be equal to or less than the equator radius.

A convex portion 11P is formed on the front surface of the base portion 11 (see FIGS. 3 and 4). The convex portion 11P extends along the upper side 11T, the left side 11L, and the right side 11R. The convex portion 11P is located slightly inside the outer peripheral edge of the base portion 11. The convex portion 11P functions as a guide for defining the mounting position of the cover 40, which will be described later.

As shown in FIGS. 6 to 8, the electronic circuit board 20 includes a printed wiring board 21, light emitting diodes D1 to light emitting diodes D7, and a connector 22. The printed wiring board 21 is arranged so that its thickness direction coincides with the vertical direction. The printed wiring board 21 is curved in a bow shape along the front surface of the lower end portion of the reflector 10 in the plan view. That is, the central portion of the printed wiring board 21 in the left-right direction is located slightly ahead of both end portions. A wiring pattern is formed by copper foil on the upper surface and the lower surface of the printed wiring board 21. The wiring pattern formed on the upper surface of the printed wiring board 21 includes lands for mounting (soldering) the light emitting diodes D1 to the light emitting diodes D7, respectively. The light emitting diodes D1 to the light emitting diodes D7 are arranged on the upper surface of the printed wiring board 21 on a predetermined curve C at substantially equal intervals. The curvature of this curve C is smaller than the curvature of the equator R (the portion along the horizontal direction of the central portion in the vertical direction (see FIG. 5)) of the central portion 11C of the reflector 10. The connector 22 is mounted on the printed wiring board 21 on the lower surface.

As shown in FIG. 9, the condenser lens 30 is integrally formed. The condenser lens 30 is attached to the upper surface of the electronic circuit board 20. The condenser lens 30 is curved in a bow shape along the electronic circuit board 20 in the plan view. The condenser lens 30 includes a lens unit L1 to a lens unit L7 corresponding to each light emitting diode D1 to the light emitting diode D7. In a state where the condenser lens 30 is attached to the electronic circuit board 20, the lens portions L1 to the lens portion L7 are located directly above the light emitting diodes D1 to the light emitting diode D7, respectively. The lens unit L1 to the lens unit L7 refract the light incident from the light emitting diodes D1 to the light emitting diode D7 and concentrate the light incident on the front apex TP (the most front portion) of the central portion 11C of the reflector 10.

The cover 40 is attached to the front surface of the reflector 10 and covers the reflector 10, the electronic circuit board 20, and the condenser lens 30 (see FIG. 2). As shown in FIGS. 10 and 11, the cover 40 has a front plate portion 41 and a side plate portion 42. The cover 40 exhibits an isosceles trapezoid equivalent to that of the reflector 10 when viewed from the front. The front plate portion 41 is gently curved so that the central portion thereof is located in front of the peripheral edge portion. The side plate portion 42 extends slightly rearward from the upper peripheral edge, the right peripheral edge, and the left peripheral edge of the front plate portion 41. The side plate portion 42 extends along the upper peripheral edge, the right peripheral peripheral edge, and the left peripheral peripheral edge of the front plate portion 41. The cover 40 is a half mirror. That is, a part (about half) of the light incident on the rear surface of the cover 40 is reflected, and a part (the other half) of the light is transmitted, and the cover 40 is attached to the reflector 10. In this state, the inside of the light emitting device 1 for a game machine can hardly be visually recognized from the front surface of the cover 40.

The connector 22 of the light emitting device 1 for a game machine and the control device 50 configured as described above are connected via a cable CA (see FIG. 2). The control device 50 is attached to the rear surface of the game board PB or a case arranged behind the game board PB. The control device 50 includes a computer device including an arithmetic unit, a memory, a timer, and the like. Further, the control device 50 includes a power supply circuit that controls the electric power supplied to the light emitting diodes D1 to the light emitting diodes D7. This power supply circuit is controlled by a computer device, and power is supplied to the light emitting diodes D1 to the light emitting diodes D7 via the cable CA. As a result, the lighting and extinguishing of the light emitting diodes D1 to the light emitting diodes D7 are controlled. For example, when a predetermined condition (for example, winning a prize) is satisfied during the game, the control device 50 first turns on the light emitting diode D1 and turns off the light emitting diodes D2 to the light emitting diode D7, as shown in FIG. When this state is set and a predetermined time Δt (for example, 0.2 seconds) elapses, the control device 50 turns on the light emitting diode D2 and turns off the light emitting diode D1 and the light emitting diodes D3 to D7. In this way, the control device 50 lights the light emitting diodes D1 to the light emitting diodes D7 one by one in the order in which they are arranged. The control device 50 turns on the light emitting diode D1 again after the light emitting diode D7. However, in a predetermined time T (for example, 1.4 seconds) from turning off the light emitting diode D7 to turning on the light emitting diode D1 again, the light emitting diodes D1 to the light emitting diodes D7 are turned off.

As described above, the light emitted from the light emitting diodes D1 to the light emitting diodes D7 is collected by the lens portions L1 to L7 at the front apex TP (the most front portion) of the central portion 11C of the reflector 10. Be lit. Therefore, it seems that one light emitting body exists in the central portion of the light emitting device 1 for a game machine. The light focused on the apex TP of the central portion 11C is reflected by the apex TP, and a part (about half) of the light is transmitted through the cover 40. Further, the remaining portion (about half) of the light reflected by the apex TP is reflected by the rear surface of the cover 40, and further reflected by the reflector 10. As described above, the light emitted from the light emitting diodes D1 to the light emitting diodes D7 is repeatedly reflected between the cover 40 and the reflector 10, and a part of the light is transmitted through the cover 40 in the middle of the reflection. As a result, the reflector 10 appears to be shining as a whole. Here, the central portion 11C of the base portion 11 projects forward when viewed from the peripheral portion thereof. The front surface of the central portion 11C corresponds to the surface of the front portion (see FIG. 5) of the spheroid. Therefore, the central portion 11C appears to shine a little brighter than the surrounding portion. That is, it seems that one substantially spherical light emitting body exists in the central portion of the game machine light emitting device 1. Then, the light emitting diodes D1 to the light emitting diodes D7 are lit in the order in which they are arranged. Therefore, it seems that the reflecting mirror is rotating around one substantially spherical light emitting body provided in the central portion of the game machine light emitting device 1. As described above, according to the game machine light emitting device 1 according to the present embodiment, the revolving light can be faithfully simulated.

Further, in the conventional light emitting device for a game machine, the reflecting member is formed in a semicircular truncated cone shape, and a plurality of light emitting bodies are arranged on a semicircular arc on the electronic circuit board. On the other hand, in the game machine light emitting device 1 according to the present embodiment, the front surface of the central portion 11C corresponds to the surface of the front portion (see FIG. 5) of the spheroid. That is, the amount of protrusion of the central portion 11C (height of protrusion from the peripheral portion of the central portion 11C at the base portion 11) is smaller than the radius (half of the minor axis) of the spheroid. Further, the light emitting diodes D1 to the light emitting diodes D7 are arranged on a predetermined curve C on the upper surface of the printed wiring board 21, and the curvature of this curve C is smaller than the curvature of the equator R of the central portion 11C. Since the curve C is set relatively gently in this way, the dimensions of the electronic circuit board 20 in the front-rear direction can be set relatively small. Therefore, the light emitting device 1 for a game machine is thinner than the conventional light emitting device for a game machine. When the light emitting diodes D1 to the light emitting diodes D7 are arranged on a relatively gentle curve C, the light emitting diodes on both ends in the arrangement direction are arranged at positions relatively far from the central portion 11C. Therefore, in the present embodiment, the light emitted from these light emitting diodes is concentrated on the central portion 11C by using the condenser lens 30.

Furthermore, the practice of the present invention is not limited to the above-described embodiment, and various changes can be made as long as the object of the present invention is not deviated.

For example, in the above embodiment, of the two adjacent light emitting diodes, the timing of turning off the light emitting diode that emits light first and the timing of turning on the light emitting diode that emits light next are the same (see FIG. 12). Instead of this, the lighting timing of the next light emitting diode may be set slightly before the extinguishing timing of the light emitting diode that has been made to emit light earlier among the two adjacent light emitting diodes.

Further, in the above embodiment, the central portion 11C of the reflector 10 is curved so as to bulge toward the player. However, instead of this, as shown in FIG. 13, a reflector 10A having a curved shape so that the central portion is recessed toward the side opposite to the player may be used. In this case, an electronic circuit board 20A in which light emitting diodes are arranged on a straight line extending in the left-right direction may be used, and a condenser lens 30A extending in the left-right direction may be used. Then, the light emitted from the light emitting diode may be concentrated on the most recessed portion of the reflector 10A on the side opposite to the player. In this case, the cover 40 of the above embodiment may be used. Further, the position slightly deviated from the central portion of the reflector 10 may be curved. Further, the arrangement position of the electronic circuit board 20 is not limited to the above embodiment. That is, the electronic circuit board 20 may be arranged outside the curved portion of the reflector 10. For example, the electronic circuit board 20 may be arranged above, to the right, or to the left of the reflector 10. Further, for example, the electronic circuit board 20 may be arranged above and below the reflector 10.
