Description

The present invention relates to a game machine such as a slot machine installed in a game hall such as a pachinko parlor.

Slot machines are widely known as game machines installed in amusement parks such as pachinko parlors. The slot machine is provided with, for example, an illumination device that illuminates a decorative panel (panel) on which a model name, a character pattern, etc. are written to produce a slot machine. In the lighting device, in order to illuminate the decorative panel more effectively, an optical functional member is arranged between the light source substrate on which the light source is mounted and the decorative panel.

Optical functional members include a reflector that has a peripheral wall surrounding the light path (illumination light path) of the illumination light from the light source and guides the illumination light to the decorative panel, and a lens cut composed of a plurality of light scattering surfaces having different angles. Examples thereof include an inner lens that is provided and inserted into the illumination optical path to change the mode of the illumination light (see Patent Document 1 below).

JP 2015-162417

However, in the lighting device described in Patent Document 1, since the inner lens is arranged between the reflector and the light source substrate, a gap corresponding to the thickness of the inner lens is created between the reflector and the light source substrate. There is a problem that light leaks from this gap and the lighting effect is reduced.

In order to prevent this, it is conceivable to arrange the inner lens on the inner peripheral portion of the reflector. However, in this case, there is a problem that it is difficult to reliably support the inner lens without lowering the lighting effect. That is, when a support member for supporting the inner lens is provided in front of (or after) the inner lens, this support member is located in the inner peripheral portion of the reflector, that is, in the illumination optical path, and the illumination effect is reduced. It ends up. On the other hand, when the support member as described above is abolished and the inner lens is supported from the side by the inner circumference of the reflector, for example, the inner lens may not be sufficiently supported and may fall off.

Further, the inner lens is generally molded by injection molding in which a resin is injected into a mold (molding mold). The mold for molding the inner lens is provided with a separation portion that can be separated from the mold body (mold body), and the inner lens is cured in the mold and then separated from the mold body. Is pressed from an opening or the like formed by separating the mold and is removed from the mold body. For this reason, there is also a problem that the lighting effect is lowered due to the formation of pressing marks on the inner lens and the formation of burrs due to resin entering the gap between the mold body and the separating portion.

The present invention has been made in view of the above background, and provides a gaming machine capable of preventing deterioration of the lighting effect and reliably supporting the inner lens while arranging the inner lens on the inner peripheral portion of the reflector. The purpose is.

In order to achieve the above object, the gaming machine of the present invention has a panel arranged on the front side of the gaming machine main body and illuminated by a light source from the back side, and a peripheral wall surrounding an optical path of illumination light from the light source. A reflector that guides the illumination light to the panel, and an inner lens whose main body is arranged on the inner peripheral portion of the reflector and for changing the mode of the illumination light transmitted through the main body are provided. The inner lens includes a protruding portion formed so as to project laterally from the main body portion, and the protruding portion includes a locking groove formed on the peripheral wall when the inner lens is attached to the reflector. It is characterized in that it functions as an engaging member to be engaged and also functions as a pressed member that is pressed when the inner lens is removed from the molding die for molding the inner lens.

The outer peripheral portion of the main body portion is formed to have substantially the same shape and size as the inner peripheral portion of the reflector, and the protruding portion is an optical path of the illumination light when the inner lens is attached to the reflector. It may be arranged outside the.

In a state where the inner lens is attached to the reflector, the protruding portion and the reflector may be flush with each other at the end faces in the optical axis direction of the illumination light.

The locking groove may be formed so that the depth, which is the length in the direction parallel to the thickness direction of the peripheral wall, is shallower than the thickness of the peripheral wall so as not to penetrate the peripheral wall.

In the present invention, since the inner lens is arranged on the inner peripheral portion of the reflector, the inner lens is arranged between the reflector and the light source substrate, as in the case where the inner lens is arranged between the reflector and the light source substrate or between the reflector and the panel. There is no gap between the reflector and the panel, which reduces the lighting effect.

Further, in the present invention, the inner lens is formed by forming a protruding portion so as to project laterally from the main body portion of the inner lens, and engaging this protruding portion with a locking groove formed on the peripheral wall of the reflector to form the inner lens. Since it is attached to the reflector, it is possible to reliably support the inner lens without deteriorating the lighting effect.

Specifically, since the inner lens is supported by engaging the protruding portion with the locking groove, the side surface of the main body of the inner lens is supported by the inner circumference (peripheral wall) of the reflector without providing the protruding portion. In comparison, it is possible to support the inner lens more reliably.
Further, since the inner lens (protruding portion) is supported by the groove (locking) formed on the peripheral wall of the reflector, the support member for supporting the inner lens is not inserted into the illumination optical path, and the illumination effect is achieved. It is possible to prevent the problem that the value is lowered.

Further, since the protruding portion functions as a pressed member to be pressed when the inner lens is removed from the molding mold for molding the inner lens, the protruding portion is not provided and the main body portion of the inner lens is pressed. Compared with the case where the inner lens is removed from the molding die, pressing marks are not generated on the main body of the inner lens, and the problem that the lighting effect is lowered can be prevented.
Further, in order to press the inner lens and remove it from the molding die, the molding die is provided with a separating portion separated from the mold body, and burrs and the like are generated in the vicinity of the pressed member due to this separating portion. However, in the present invention, since the pressed member is a protruding portion and burrs are generated on the protruding portion and not on the main body portion of the inner lens, it is possible to prevent a problem that the lighting effect is lowered.

As shown in FIG. 1, the slot machine (game machine) 10 includes a storage box 11 and a front door 12, and the game machine main body is composed of these. The storage box 11 contains a reel unit in which a plurality of reels are unitized, a hopper device for paying out medals, and the like. The front door 12 is divided into an upper door 12a and a lower door 12b, and the upper door 12a and the lower door 12b are respectively pivotally attached to the storage box 11 and supported so as to be openable and closable.

The upper door 12a is provided with a liquid crystal display 15 for displaying various images and a transparent window 16 for visually recognizing the reels on the front surface thereof. A plurality of types of symbols are arranged on the outer peripheral surface of the reel, and when the reels are stopped, three symbols are displayed for each reel through the transparent window 16.

The lower door 12b has a medal insertion slot 22 for inserting medals, a bet button 23 operated when betting a credited medal, a start lever 24 operated when starting a game, and a rotating reel. Stop buttons 26a to 26c for stopping, a medal tray 28 for receiving medals paid out from the hopper device, and a clearing button 29 for clearing credited medals are provided.

In the slot machine 10, the start lever 24 is activated when a medal is inserted into the medal insertion slot 22 or the bet button 23 is operated, and the game is started when the activated start lever 24 is operated. Will be done. When the game is started, a winning combination lottery is executed to determine one of a plurality of types of winning combinations or a loss, and the reels start rotating. When the rotation speed of the reel reaches a constant speed and becomes steady rotation, the operation of the stop buttons 26a to 26c is enabled, and when the activated stop buttons 26a to 26c are operated, the reel corresponding to the operated stop button is stopped. Can be made to. Then, when all the reels are stopped, if the symbol combination corresponding to the winning combination determined in the winning combination lottery is displayed, this winning combination becomes a prize, and the process corresponding to the winning combination (winning process). Is executed.

<Illuminations unit>
Further, the slot machine 10 is provided with an illumination unit (illumination device) 30 at the center of the upper end of the upper door 12a. The illumination unit 30 includes an outer cover 32, and a frame portion 32a is formed at the front end portion of the outer cover 32. A decorative panel (panel) 34 is arranged behind the frame portion 32a.
The decorative panel 34 includes a print sheet on which the model name of the slot machine 10 and a character symbolizing the slot machine 10 are printed, a transparent protective panel arranged on the front surface of the print sheet, and the like, and is formed on a light source substrate 36 described later. The slot machine 10 is illuminated from the back side by the illumination light from the mounted LED (light source) 36a.

As shown in FIGS. 2 and 3, the illumination unit 30 includes the above-mentioned outer cover 32, the decorative panel 34, the light source substrate 36, and the optical functional member 38. The optical functional member 38 is arranged behind the decorative panel 34, and the decorative panel 34 is sandwiched and supported between the front end portion of the optical functional member 38 and the outer cover 32 (frame portion 32a). A light source substrate 36 is arranged behind the optical functional member 38. The light source substrate 36 is attached to the front side of the base member 40, and is arranged together with the base member 40 on the back side of the optical functional member 38.

<Assembly structure of reflector and inner lens>
As shown in FIG. 4, the optical functional member 38 is composed of a reflector 42 and inner lenses 44 and 46 assembled to the reflector 42 from the front side of the reflector 42.

The reflector 42 is formed of, for example, a white resin, and includes a peripheral wall 48 and a partition wall (peripheral wall) 50.
The peripheral wall 48 is formed in a tubular shape that surrounds the entire light path (illumination light path) of the illumination light from the LED 36a of the light source substrate 36, and is provided so as to connect the decorative panel 34 and the light source substrate 36, and is provided from the light source substrate 36. It has a function of guiding the illumination light to the decorative panel 34.
On the other hand, the partition wall 50 is provided so as to partition the area surrounded by the peripheral wall 48 to the left and right, and serves as a partition plate for partitioning the illumination area illuminated by the LED 36a of the light source substrate 36 into two, a left side and a right side. Has a function. In other words, the partition wall 50 cooperates with the peripheral wall 48 to function as a peripheral wall surrounding the illumination light path for illuminating the left illumination area and for illuminating the illumination light for the right illumination area. It has both a function as a surrounding wall.
As described above, the partition wall 50 not only functions as a partition plate for partitioning the illumination area, but also functions as a peripheral wall surrounding the illumination optical path. Therefore, the partition wall 50 will be referred to as a peripheral wall 50 below.

As shown in FIG. 5 (A), which is an enlargement of the range A1 surrounded by a circular broken line in FIG. 4, the peripheral wall 48 engages with a protrusion 58 described later to support the inner lenses 44 and 46 (this implementation). In the form, an engaging groove 52 is provided mainly for restricting the movement to the rear (rear and left / right). In the present embodiment, the engaging groove 52 is formed so as to penetrate the peripheral wall 48.
By doing so, the inner lenses 44 and 46 can be supported more reliably. On the other hand, since the engaging groove 52 penetrates the peripheral wall 48, the illumination light leaking from the engaging groove 52 only illuminates the inner portion of the outer cover 32.

Further, as shown in FIG. 5B, which is an enlarged view of the range B1 surrounded by the circular broken line in FIG. 4, the peripheral wall 50 engages with the protrusion 60 described later to support the inner lenses 44 and 46 ( In this embodiment, an engaging groove 54 is provided mainly for restricting the movement to the rear (rearward and vertical). In the present embodiment, the engaging groove 54 is formed within the thickness range of the peripheral wall 50 so as not to penetrate the peripheral wall 50. That is, the depth, which is the length in the direction parallel to the thickness direction of the peripheral wall 50, is formed to be shallower than the thickness of the peripheral wall 50.
By doing so, the protrusion 60 is made smaller than the case where the engaging groove 54 penetrates the peripheral wall 50, but the illumination light does not leak to the adjacent illumination optical path, so that the illumination effect is reduced. It won't end up. That is, since the peripheral wall 50 has a function as a partition plate for partitioning the left and right illumination optical paths, if there is a penetrating portion in the peripheral wall 50, the illumination light leaking from the penetrating portion leaks to the illumination optical path on the opposite side, so that the illumination effect is obtained. However, there is no such problem in the present embodiment.

Returning to FIG. 4, the inner lenses 44 and 46 are formed by, for example, injection molding in which a transparent resin is injected into a mold (molding mold), and include a main body portion 56 and protruding portions 58 and 60.
The main body 56 is formed in a plate shape, and the plate surface (front surface, back surface, or both sides) of the main body 56 is provided with a lens cut composed of a plurality of light refracting surfaces having different angles. As a result, the main body 56 has a function of scattering the transmitted light.
Since the inner lenses 44 and 46 need only have a function of converting the transmitted light, for example, a plurality of convex lenses and concave lenses are arranged on the plate surface of the main body 56 to partially transmit the transmitted light. Specific specifications can be appropriately changed, such as using lenses having a function of condensing or diffusing as inner lenses 44 and 46.

Further, the main body 56 of the inner lens 44 is the illumination optical path on the left side of the two left and right illumination optical paths partitioned by the peripheral wall 50 when facing the front surface of the game machine main body (the reflector 42 formed by the peripheral walls 48 and 50). Of the two inner peripheral parts, the inner peripheral part on the left side when facing the main body of the game machine) is formed to be substantially the same size. Then, the inner lens 44 is arranged in the illumination optical path (inner peripheral portion) on the left side.
Similarly, the main body 56 of the inner lens 46 has two of the two left and right illumination optical paths partitioned by the peripheral wall 50, the illumination optical paths on the right side of the game machine main body (the reflector 42 formed by the peripheral walls 48 and 50). Of the inner peripheral part, the size is almost the same as the inner peripheral part on the right side when facing the game machine main body). Then, the inner lens 46 is arranged in the illumination optical path (inner peripheral portion) on the right side.

As described above, in the slot machine 10, the inner lenses 44 and 46 (main body portion 56) are arranged on the inner peripheral portion of the reflector 42. Therefore, for example, as in the case where the inner lenses 44 and 46 are integrated into one plate and arranged between the reflector 42 and the decorative panel 34, there is a gap between the reflector 42 and the decorative panel 34. The lighting effect does not deteriorate due to the leakage of the illumination light from this gap.

The projecting portions 58 and 60 are formed so as to project from the outer surface of the main body portion 56 toward the side of the main body portion 56. Further, the protruding portion 58 is formed at a position corresponding to the engaging groove 52, and the protruding portion 60 is formed at a position corresponding to the engaging groove 54. The protruding portion 58 is engaged with the engaging groove 52 and the protruding portion 60 is engaged with the engaging groove 54, respectively, and the inner lenses 44 and 46 are supported by this engagement.
In this way, the protrusions 58 and 60 are provided, and the protrusions 58 and 60 are engaged with the engagement grooves 52 and 54 to support the inner lenses 44 and 46, thereby supporting the protrusions 58 and 60. The inner lenses 44 and 46 can be supported more reliably than in the case where the inner lenses 44 and 46 are not provided.

Further, the projecting portions 58 and 60 are formed so as to project outward from the main body portion 56 formed to have substantially the same size as the two inner peripheral portions on the left and right provided on the reflector 42, and are formed on the peripheral wall 48 and the peripheral wall 50. It is engaged with the engaging grooves 52 and 54. That is, the protrusions 58 and 60 are not arranged on any of the two left and right inner peripheral portions provided on the reflector 42, but are arranged in an area overlapping the peripheral walls 48 and 50. In other words, the protrusions 58 and 60 are arranged outside the illumination optical path (outside the illumination optical path) of the illumination light from the LED 36a. Therefore, the lighting effect is not reduced by the protrusions 58 and 60.

The protrusions 58 and 60 arranged outside the illumination optical path in this way do not deteriorate the illumination effect even if scratches, dents, burrs, etc. are generated. Therefore, in the manufacturing process of the inner lenses 44 and 46, the inner lenses 44 and 46 are removed from the molding mold for molding the inner lenses 44 and 46 by pressing the protruding portions 58 and 60. That is, the protruding portions 58 and 60 function as pressed portions that are pressed when the inner lenses 44 and 46 are removed from the molding die. This makes it possible to prevent a decrease in the lighting effect.

That is, the inner lenses 44 and 46 are formed by injection molding in which resin or the like is injected into the molding die, but the molding die is provided with a mold body and a separable portion that can be separated from the mold body, and the inner lenses 44 and 46 are provided. Is cured in the mold and then pressed from an opening or the like formed by separating the separation portion from the mold body and removed from the mold body.
At this time, if the main body 56 of the inner lenses 44 and 46 is used as the pressed portion, a pressing mark is generated on the main body 56.
Further, in the configuration (molding mold) in which the main body 56 of the inner lenses 44 and 46 is the pressed portion, the pressing portion, that is, the portion where the separating portion of the molding mold is arranged is the main body 56 of the inner lenses 44 and 46. It becomes. Then, burrs are generated in this portion due to the resin entering the gap between the main body portion and the separating portion of the molding die.
As described above, in the configuration in which the main body 56 of the inner lenses 44 and 46 is the pressed portion, the lighting effect is lowered due to the formation of pressing marks and burrs on the main body 56.
On the other hand, in the slot machine 10, since the protruding portions 58 and 60 arranged outside the illumination optical path are the pressed portions, the illumination effect does not deteriorate even if pressing marks or burrs are generated. ..

As shown in FIG. 6A, which is an enlarged view of the range A2 surrounded by the circular broken line in FIG. 3, in the present embodiment, the front end surface of the protrusion 58 is located forward of the front surface of the main body 56. When the inner lenses 44 and 46 are assembled to the reflector 42, the protrusion 58 is directed forward so that the front end surface of the protrusion 58 is flush with the front end surface of the reflector 42 (peripheral wall 48). It is extended.
Similarly, as shown in FIG. 6B, which is an enlarged view of the range B2 surrounded by a circular broken line in FIG. 3, in the present embodiment, the front end surface of the protrusion 60 is located forward of the front surface of the main body 56. In addition, when the inner lenses 44 and 46 are assembled to the reflector 42, the protrusion 60 is directed forward so that the front end surface of the protrusion 60 is flush with the front end surface of the reflector 42 (peripheral wall 50). It is extended.

By doing so, the back surface of the decorative panel 34 is applied with an even force by the front end surfaces of the optical functional member 38 (the front end surfaces of the reflectors 42 (peripheral walls 48 and 50) and the inner lenses 44 and 46 (protruding portions 58 and 60)). It can be pressed and the deterioration of the lighting effect can be prevented.
That is, when the front end surfaces of the reflector 42 (peripheral walls 48, 50) and the inner lenses 44, 46 (protruding portions 58, 60) are not flush with each other, the force for pressing the back surface of the decorative panel 34 becomes non-uniform, and the decorative panel 34 becomes uneven. The lighting effect is reduced due to distortion. In particular, thin members such as print sheets are likely to be distorted and the lighting effect is likely to be reduced. On the other hand, in the present embodiment, since the front end surfaces of the reflector 42 (peripheral walls 48, 50) and the inner lenses 44, 46 (protruding portions 58, 60) are flush with each other, the back surface of the decorative panel 34 is evenly applied. Can be pressed. As a result, distortion of the decorative panel 34 can be prevented, and deterioration of the lighting effect can be prevented.

In the example, both the protrusions 58 and 60 are extended forward so as to be flush with the front end faces of the reflectors 42 (peripheral walls 48 and 50), but only one of the protrusions 58 and 60 is forward. It may be extended so as to be flush with the front end surface of the reflector 42.

<Light source escape structure>
As described above, in the slot machine 10, by devising the assembly structure of the reflector 42 and the inner lenses 44 and 46, the inner lenses 44 and 46 are surely supported and the deterioration of the lighting effect is prevented. In the slot machine 10, in addition to the above, the structure of the rear end portion of the reflector 42 is devised to improve the design while suppressing the cost. Hereinafter, the structure of the rear end portion of the reflector 42 will be described with reference to FIGS. 7 to 9.

As shown in FIG. 7, a light source substrate 36 on which a plurality of LEDs 36a are mounted is provided on the back side of the reflector 42. Then, as shown in FIG. 8, the reflector 42 and the light source substrate 36 are supported in a state where the back surface of the reflector 42 and the front surface of the light source substrate 36 face each other. By doing so, the illumination light from the LED 36a can be incident on the inside (inner peripheral portion) of the reflector 42 without leakage, and the decorative panel 34 can be efficiently illuminated. In FIG. 8, only the back side of the reflector 42 is indicated by a broken line, and the illustration of the front side is omitted.

As described above, the reflector 42 is provided with two left and right illumination optical paths by further partitioning the area surrounded by the peripheral wall 48 by the peripheral wall 50. Then, the illumination light from the LED 36a mounted on the left side of the light source substrate 36 is incident on the illumination optical path on the left side. Further, the illumination light from the LED 36a mounted on the right side of the light source substrate 36 is incident on the illumination optical path on the right side. Then, the lighting mode of each LED 36a is controlled for each corresponding illumination optical path.

As described above, in the present embodiment, the reflector 42 is provided with two illumination light paths on the left and right, but the specific shape of the reflector 42 (peripheral walls 48, 50), that is, the number of illumination light paths to be provided and the shape of each illumination light path. Regarding the size and size, and the shape of the entire illumination light path that integrates each illumination light path, the design of the decorative panel illuminated by the illumination light from each illumination light path (the shape of the entire decorative panel and the pattern described on the decorative panel) It is determined by the content of the characters). Therefore, it differs depending on the model of the slot machine.

On the other hand, as for the light source substrate 36, the LED 36a may be uniformly arranged over the entire light source substrate 36, and a common light source substrate 36 may be used even for different models. A common light source substrate 36 is used. By doing so, the cost can be suppressed.

However, as described above, since the shape of the reflector 42 (peripheral walls 48, 50) differs depending on the slot machine model depending on the design of the decorative panel, the front of the LED 36a (irradiation direction of the illumination light) depends on the design of the decorative panel. ) And the reflector 42 (peripheral walls 48, 50) may be in a positional relationship. Further, also in this embodiment, the peripheral wall 50 is provided so as to have a positional relationship of overlapping in front of the LED 36a mounted in the center of the light source substrate 36.

When the peripheral wall 50 and the LED 36a overlap in this way, there is a problem that the peripheral wall 50 comes into contact with the LED 36a and the LED 36a is damaged.
Further, when the peripheral wall 50 and the LED 36a overlap, the LED 36a is sandwiched between the front surface of the light source substrate 36 and the peripheral wall 50 which should originally face each other, so that a gap is provided between the light source substrate 36 and the back surface of the peripheral wall 50. In this embodiment, the LED 36a (LED 36a overlapping the peripheral wall 50) arranged in the center of the light source substrate 36 has a problem that the illumination light leaks from the gap to the adjacent illumination optical paths. Originally, the illumination light is incident on the illumination light path on the right side, but if there is a gap between the light source substrate 36 and the peripheral wall 50, the illumination light from the LED 36a leaks to the illumination light path on the left side.
On the other hand, determining the side to be illuminated according to the position of the LED 36a, that is, the design of the decorative panel, causes a deterioration in design.

Therefore, in the slot machine 10, a relief portion 70 is formed in the peripheral wall 50 at a position where it may come into contact with the LED 36a (in the present embodiment, the back surface side of the peripheral wall 50).
As shown in FIG. 9, the relief portion 70 sets the distance between the LED 36a and the peripheral wall 50 in the direction perpendicular to the light source substrate 36 (illumination light irradiation direction) to L1, and the LED 36a and the peripheral wall 50 in the direction parallel to the light source substrate 36. Is formed by cutting out a part of the peripheral wall 50 so that both L1 and L2 are at least a predetermined distance (for example, 2 mm) when the distance is L2.
By doing so, it is possible to prevent damage to the LED 36a and light leakage to the adjacent region (illumination optical path) without deteriorating the design.

In the above embodiment, the peripheral wall 50 and the LED 36a overlap in the irradiation direction of the illumination light, and the relief portion 70 is formed by cutting out the peripheral wall 50. However, the present invention is limited to this. Not done. For example, when the peripheral wall 48 and the LED 36a overlap in the irradiation direction of the illumination light, the peripheral wall 48 may be cut out to form a relief portion. Of course, the escape portion is not limited to one location, and may be provided at a plurality of locations.

Further, in the above embodiment, an example in which a relief portion is provided at a portion where the LED 36a and the reflector 42 (peripheral wall 50) overlap (overlap) in the irradiation direction of the illumination light has been described, but as shown in FIG. A relief portion 80 may be provided at a portion where the LED 36a and the reflector 42 (peripheral wall 50) do not overlap (do not overlap) in the irradiation direction of the illumination light.
In FIG. 10, the relief portion 80 is formed so that both L1 and L2 are at least a predetermined distance, similarly to the above-mentioned relief portion 70 (see FIG. 8).
In the description using the drawings after FIG. 10, the same members as those in the above-described embodiment are designated by the same reference numerals, and the description thereof will be omitted.

Further, in the above embodiment, the example in which the relief portion is formed so that both L1 and L2 are at least a predetermined distance has been described, but the present invention is not limited to this. For example, the relief portion may be formed so that the L1 is at least the first predetermined distance and the L2 is at least the second predetermined distance.

In this case, it is preferable that the second predetermined distance is set longer than the first predetermined distance.
That is, the values of L1 and L2 change due to manufacturing error, assembly error, and the like, but the values of L1 change only depending on the relationship between the reflector 42 and the light source substrate 36 (manufacturing error and assembly error). On the other hand, the value of L2 changes depending not only on the relationship between the reflector 42 and the light source substrate but also on the relationship between the base member 40 to which the light source substrate 36 is attached. As described above, since the value of L2 changes due to the influence of manufacturing error and assembly error of more members than that of L1, the range of the changing value tends to be large.
Therefore, by setting the second predetermined distance to be larger than the first predetermined distance, it is possible to more reliably prevent the contact between the LED 36a and the reflector 42.

Further, it is preferable to set the second predetermined distance in consideration of terminals called LED legs. That is, some LEDs have legs extending outward. When the present invention is applied to a slot machine using such an LED, the first predetermined distance is set so that the feet and the parts where the feet are connected to the light source substrate (such as the parts to be soldered) do not come into contact with the reflector. It is preferable to set a second predetermined distance.

Further, in the above embodiment, the example in which the relief portion is formed by cutting out the peripheral wall 50 of the reflector has been described, but the present invention is not limited to this. For example, as shown in FIG. 11, the relief portion 90 may be formed by bending the peripheral wall 85 of the reflector into a hook shape.
When a lighting substrate common to other models is used, depending on the design of the decorative panel, it is conceivable that an LED that is not used (does not emit light) may be generated. In such a case, as shown in FIG. 12, the relief portion 100 may be formed so as to surround the unused LED 36a.
