Description

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

  Slot machines are widely known as gaming machines installed in amusement halls such as pachinko parlors. For example, the slot machine is provided with an illumination device that produces a slot machine by illuminating a decorative panel (panel) on which a model name, a character pattern, and the like are described. In the electrical decoration device, an optical functional member is disposed between the light source substrate on which the light source is mounted and the decorative panel in order to illuminate the decorative panel more effectively.

  Examples of the optical functional member include a reflector that has a peripheral wall that surrounds the optical path of the illumination light from the light source (illumination optical path), guides the illumination light to the decorative panel, and a lens cut that includes 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 convert the illumination light (see Patent Document 1 below).

JP2015-162417

  However, since the inner lens is disposed between the reflector and the light source substrate in the electrical decoration device described in Patent Document 1, a gap corresponding to the thickness of the inner lens is formed between the reflector and the light source substrate. There is a problem that light leaks from the gap and the illumination effect is lowered.

  In order to prevent this, it is conceivable to dispose 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 reducing the illumination effect. In other words, when a support member that supports the inner lens is provided in front of (or behind) the inner lens, the 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. End up. On the other hand, when the support member as described above is eliminated and, for example, the inner lens is supported from the side on the inner periphery of the reflector, there is a possibility that the support member cannot 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 die). The mold for molding the inner lens is provided with a separation part that is separable from the mold body (mold body). After the inner lens is cured in the mold, the separation part is separated from the mold body. Is removed from the mold body by being pressed from an opening formed by separating the. For this reason, there is a problem that the illumination effect is deteriorated due to a press mark on the inner lens or a burr caused by a resin entering the gap between the mold body and the separation part.

  The present invention has been made in view of the above-described background, and provides a gaming machine that can prevent a decrease in illumination effect and can reliably support the inner lens while disposing the inner lens on the inner peripheral portion of the reflector. The purpose is that.

  In order to achieve the above object, a gaming machine of the present invention has a panel that is disposed on the front side of a gaming machine main body and is illuminated by a light source from the back side, and a peripheral wall that surrounds an optical path of illumination light from the light source. A reflector for guiding the illuminating light to the panel; and an inner lens for converting a form of the illuminating light that is disposed in an inner peripheral portion of the reflector and transmits the main body. The inner lens includes a protrusion formed so as to protrude laterally from the main body, and the protrusion includes a locking groove formed in the peripheral wall when the inner lens is attached to the reflector. It functions as an engaging member that engages, and functions as a pressed member that is pressed when the inner lens is removed from a mold for molding the inner lens. There.

  The outer peripheral portion of the main body is formed in 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 on the outside.

  In the state where the inner lens is attached to the reflector, the projecting portion and the reflector may be flush with the end surfaces in the optical axis direction of the illumination light.

  The locking groove may be formed so that the depth, which is the length in a 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 disposed on the inner peripheral portion of the reflector, the inner lens is disposed between the reflector and the light source substrate, as in the case where the inner lens is disposed 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 and the lighting effect is not reduced.

  In the present invention, a protrusion is formed so as to protrude sideways from the main body of the inner lens, and this protrusion is engaged with a locking groove formed on the peripheral wall of the reflector. Since it is attached to the reflector, it is possible to reliably support the inner lens without reducing the illumination effect.

Specifically, since the inner lens is supported by engaging the protruding portion with the locking groove, the side surface of the inner lens body portion is supported by the inner circumference (peripheral wall) of the reflector without providing the protruding portion. In comparison, the inner lens can be more reliably supported.
In addition, since the inner lens (protruding portion) is supported by the groove (locking) formed in 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 Can be avoided.

Furthermore, since the protrusion functions as a pressed member that is pressed when the inner lens is removed from the mold for forming the inner lens, the protrusion is not provided and presses the main body of the inner lens. Compared with the case where the inner lens is removed from the mold, there is no occurrence of pressing marks in the main body of the inner lens, and the problem that the illumination effect is reduced can be prevented.
Further, in order to press the inner lens and remove it from the mold, the mold has a separation part separated from the mold body, and a burr or the like is generated in the vicinity of the pressed member due to the separation part. In some cases, however, in the present invention, the member to be pressed is the protruding portion, and the burr is generated in the protruding portion and does not occur in the main body portion of the inner lens.

  As shown in FIG. 1, the slot machine (game machine) 10 includes a storage box 11 and a front door 12, and a gaming machine main body is constituted by these. The storage box 11 stores 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. The upper door 12a and the lower door 12b are pivotally attached to the storage box 11 and supported so as to be freely opened and closed.

  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 reel on the front surface. A plurality of types of symbols are arranged on the outer peripheral surface of the reel. When the reel is stopped, three symbols are displayed for each reel through the transparent window 16.

  The lower door 12b has a medal slot 22 for inserting medals, a bet button 23 that is operated when betting credited medals, a start lever 24 that is 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 betted by inserting a medal into the medal insertion slot 22 or by operating the bet button 23, and the game starts when the activated start lever 24 is operated. Is done. When the game is started, the winning combination lottery is executed to determine one of a plurality of types of winning combinations or lose, and the reel starts to rotate. The operation of the stop buttons 26a to 26c is activated when the rotation speed of the reel reaches a constant speed and becomes a steady rotation, and when the activated stop buttons 26a to 26c are operated, the reel corresponding to the operated stop button is stopped. Can be made. When all the reels are stopped and the symbol combination corresponding to the winning combination determined in the winning combination lottery is displayed, the winning combination is won, and the process corresponding to the winning winning combination (winning process) Is executed.

<Lighting unit>
Further, the slot machine 10 is provided with an electric decoration unit (electric decoration device) 30 at the center of the upper end of the upper door 12a. The electrical decoration unit 30 includes an outer cover 32, and a frame portion 32 a is formed at the front end portion of the outer cover 32. And the decorative panel (panel) 34 is arrange | positioned behind this frame part 32a.
The decorative panel 34 includes a print sheet on which a model name of the slot machine 10 and a character symbolizing the slot machine 10 are printed, a transparent protective panel disposed on the front surface of the print sheet, and the like, on a light source board 36 to be described later. Illuminated from the back side by illumination light from the mounted LED (light source) 36a, the slot machine 10 is produced.

  As shown in FIGS. 2 and 3, the electrical decoration unit 30 includes an optical functional member 38 in addition to the outer cover 32, the decorative panel 34, and the light source substrate 36 described above. The optical functional member 38 is disposed 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 disposed behind the optical function member 38. The light source substrate 36 is attached to the front side of the base member 40 and is disposed on the back side of the optical function member 38 together with the base member 40.

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

The reflector 42 is formed of, for example, white resin and includes a peripheral wall 48 and a partition wall (peripheral wall) 50.
The peripheral wall 48 is formed in a cylindrical shape surrounding the entire optical path of the illumination light (illumination optical path) from the LED 36 a of the light source substrate 36, and is provided so as to connect the decorative panel 34 and the light source substrate 36. The illumination light is guided to the decorative panel 34.
On the other hand, the partition wall 50 is provided so as to partition the region surrounded by the peripheral wall 48 to the left and right, and serves as a partition plate that partitions the illumination region illuminated by the LEDs 36a of the light source substrate 36 into two parts, the left side and the right side. It has a function. In other words, the partition wall 50 cooperates with the peripheral wall 48 to provide a function as a peripheral wall surrounding the illumination light path of the illumination light that illuminates the left illumination area and an illumination light path of the illumination light that illuminates 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 that partitions the illumination area, but also functions as a peripheral wall that surrounds the illumination optical path. Therefore, the partition wall 50 is hereinafter referred to as a peripheral wall 50.

As shown in FIG. 5A, in which the range A1 surrounded by the circular broken line in FIG. 4 is enlarged, the peripheral wall 48 is engaged with a protrusion 58 described later to support the inner lenses 44 and 46 (this embodiment). In the embodiment, an engagement groove 52 is mainly provided for restricting movement backward (backward and left and right). In the present embodiment, the engagement 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 leaked from here only illuminates the inner portion of the outer cover 32.

Further, as shown in FIG. 5B in which a range B1 surrounded by a circular broken line in FIG. 4 is enlarged, the peripheral wall 50 is engaged with a protrusion 60 described later to support the inner lenses 44 and 46 ( In the present embodiment, an engagement groove 54 is mainly provided for restricting movement backward (backward and up and down). In the present embodiment, the engagement 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 that 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 reduced in size compared with the case where the engaging groove 54 penetrates the peripheral wall 50, but the illumination effect is reduced because the illumination light does not leak into the adjacent illumination light path. There is no end. That is, the peripheral wall 50 has a function as a partition plate that partitions the left and right illumination light paths. Therefore, if there is a penetrating portion in the peripheral wall 50, the illumination light leaked from here leaks into the opposite illumination light path, thereby providing an illumination effect. However, in this embodiment, there is no such problem.

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 die), and include a main body portion 56 and projecting portions 58 and 60.
The main body 56 is formed in a plate shape, and a lens cut made of a plurality of light refracting surfaces with different angles is applied to the plate surface (front surface, back surface, or both surfaces) of the main body portion 56. Thereby, the main-body part 56 has the function to scatter the light which permeate | transmits.
The inner lenses 44 and 46 only need to 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 portion 56 to partially transmit the transmitted light. Specific specifications such as using a lens having a function of condensing or diffusing as the inner lenses 44 and 46 can be appropriately changed.

Further, the main body 56 of the inner lens 44 has an illumination light path on the left side toward the front surface of the gaming machine main body, of the left and right illumination light paths partitioned by the peripheral wall 50 (the reflector 42 formed by the peripheral walls 48 and 50). Of the two inner peripheral portions, the inner peripheral portion on the left side toward the gaming machine main body) is formed to be approximately the same size. The inner lens 44 is disposed in the illumination light path (inner peripheral portion) on the left side.
Similarly, the main body 56 of the inner lens 46 has two right and left illumination light paths (two of the reflectors 42 formed by the peripheral walls 48 and 50) toward the gaming machine body, out of the two illumination light paths partitioned by the peripheral wall 50. The inner peripheral portion is formed to have a size substantially equal to the right inner peripheral portion toward the gaming machine body. The inner lens 46 is disposed in the illumination light 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. For this reason, for example, the inner lenses 44 and 46 are integrated into a single plate, and this is disposed between the reflector 42 and the decorative panel 34, so that there is a gap between the reflector 42 and the decorative panel 34. The illumination effect does not deteriorate due to the leakage of illumination light from the gap.

The protrusions 58 and 60 are formed so as to protrude from the outer surface of the main body 56 toward the side of the main body 56. Further, the protrusion 58 is formed at a position corresponding to the engagement groove 52, and the protrusion 60 is formed at a position corresponding to the engagement groove 54. The protrusion 58 is engaged with the engagement groove 52 and the protrusion 60 is engaged with the engagement groove 54, 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 supported by supporting the inner lenses 44 and 46 by engaging the protrusions 58 and 60 with the engagement grooves 52 and 54. The inner lenses 44 and 46 can be more reliably supported as compared with the case where no lens is provided.

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

  Thus, even if the protrusions 58 and 60 arranged outside the illumination optical path have scratches, dents, burrs, etc., the illumination effect does not deteriorate. For this reason, in the manufacturing process of the inner lenses 44 and 46, the inner lenses 44 and 46 are removed from the mold for molding the inner lenses 44 and 46 by pressing the protrusions 58 and 60. That is, the protrusions 58 and 60 function as pressed parts that are pressed when the inner lenses 44 and 46 are removed from the mold. Thereby, the fall of a lighting effect can be prevented.

That is, the inner lenses 44 and 46 are formed by injection molding in which a resin or the like is injected into a molding die. The molding die is provided with a mold main body and a separation part that can be separated from the mold main body. After being cured in the mold, the mold is pressed from an opening formed by separating the separating portion from the mold body and removed from the mold body.
At this time, if the main body portion 56 of the inner lenses 44 and 46 is a pressed portion, a pressing mark is generated in the main body portion 56.
Further, in the configuration (molding die) in which the main body portion 56 of the inner lenses 44 and 46 is a pressed portion, the portion to be pressed, that is, the portion where the separation portion of the molding die is disposed is the main body portion 56 of the inner lenses 44 and 46. It becomes. And in this site | part, a burr | flash will arise when resin enters into the clearance gap between the main-body part of a shaping | molding die, and a isolation | separation part.
As described above, in the configuration in which the main body portion 56 of the inner lenses 44 and 46 is the pressed portion, a pressing mark or a burr is generated in the main body portion 56, so that the illumination effect is reduced.
On the other hand, in the slot machine 10, since the projecting portions 58 and 60 arranged outside the illumination optical path are pressed portions, the illumination effect does not deteriorate even if pressing marks or burrs are generated. .

In addition, as shown in FIG. 6A in which the range A2 surrounded by the circular broken line in FIG. 3 is enlarged, in the present embodiment, the front end surface of the protruding portion 58 is positioned forward of the front surface of the main body portion 56, In the state where 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 (the peripheral wall 48). It is extended.
Similarly, as shown in FIG. 6B in which a range B2 surrounded by a circular broken line in FIG. 3 is enlarged, in this embodiment, the front end surface of the projecting portion 60 is positioned forward of the front surface of the main body portion 56. In the state where 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 rear surface of the decorative panel 34 is applied with equal force by the front end surface of the optical functional member 38 (the front end surfaces of the reflector 42 (peripheral walls 48 and 50) and the inner lenses 44 and 46 (protruding portions 58 and 60)). It can press and can prevent the lighting effect from deteriorating.
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 pressing the back surface of the decorative panel 34 becomes uneven, and the decorative panel 34 The lighting effect is reduced due to distortion. In particular, a thin member such as a printed sheet is likely to be distorted, and there is a great possibility that the illumination effect is reduced. On the other hand, in this embodiment, since the front end surfaces of the reflector 42 (peripheral walls 48, 50) and the inner lenses 44, 46 (projections 58, 60) are flush with each other, the back surface of the decorative panel 34 can be applied with equal force. Can be pressed. Thereby, the distortion of the decorative panel 34 can be prevented and the deterioration of the lighting effect can be prevented.

  In addition, although both the protrusion parts 58 and 60 were extended ahead and demonstrated in the example made flush with the front end surface of the reflector 42 (peripheral walls 48 and 50), only one of the protrusion parts 58 and 60 was moved forward. It may extend and be flush with the front end face 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 illumination effect is prevented from being lowered while the inner lenses 44 and 46 are reliably supported. In addition to the above, in the slot machine 10, the design is improved while suppressing the cost by devising the structure of the rear end portion of the reflector 42. Below, the structure of the rear-end part of the reflector 42 is demonstrated using FIGS. 7-9.

  As shown in FIG. 7, a light source substrate 36 having a plurality of LEDs 36 a mounted on the front surface is provided on the back side of the reflector 42. As shown in FIG. 8, the reflector 42 and the light source substrate 36 are supported with the back surface of the reflector 42 and the front surface of the light source substrate 36 facing each other. By doing so, the illumination light from the LED 36a is 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 illustration of the front side is omitted.

  As described above, the reflector 42 is provided with the left and right illumination light paths by further dividing the region surrounded by the peripheral wall 48 by the peripheral wall 50. The illumination light from the LED 36a mounted on the left side of the light source substrate 36 enters the left illumination optical path. Also, the illumination light from the LED 36a mounted on the right side of the light source substrate 36 enters the right illumination light path. Each LED 36a is controlled in lighting state for each corresponding illumination light path.

  Thus, in this 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 and 50), that is, the number of illumination light paths provided and the shape of each illumination light path. As for the overall shape of the illumination light path that combines the illumination light paths, size, etc., the design of the makeup panel illuminated by the illumination light from each illumination light path (the shape of the makeup panel as a whole, Character content). For this reason, it is different for each type of slot machine.

  On the other hand, with respect to the light source board 36, there is a case where the common light source board 36 is used even in different models by arranging the LEDs 36 a uniformly over the entire light source board 36. A common light source substrate 36 is used. By doing so, costs can be reduced.

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

Thus, when the surrounding wall 50 and LED36a have overlapped, there exists a problem that the surrounding wall 50 contacts LED36a and LED36a is damaged.
Further, when the peripheral wall 50 and the LED 36a overlap each other, the LED 36a is sandwiched between the front surface of the light source substrate 36 and the peripheral wall 50 that should be opposed to each other, so that there is a gap between the light source substrate 36 and the rear surface of the peripheral wall 50. In this embodiment, the LED 36a (the LED 36a overlapping the peripheral wall 50) disposed in the center of the light source substrate 36 has a problem that the illumination light leaks to the adjacent illumination optical path from this gap. Originally, the illumination light is incident on the right illumination light path. However, if there is a gap between the light source substrate 36 and the peripheral wall 50, the illumination light from the LED 36a leaks into the left illumination light path.
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 decrease in design.

For this reason, in the slot machine 10, the escape portion 70 is formed in the peripheral wall 50 at a position that may come into contact with the LED 36a (in this embodiment, the back side of the peripheral wall 50).
As shown in FIG. 9, the escape portion 70 has a distance L1 between the LED 36a and the peripheral wall 50 in a direction perpendicular to the light source substrate 36 (irradiation direction of illumination light), and the LED 36a and the peripheral wall 50 in a direction parallel to the light source substrate 36. When the distance is set to L2, it is formed by cutting out a part of the peripheral wall 50 so that both of L1 and L2 become a predetermined distance (for example, 2 mm) or more.
By doing so, it is possible to prevent breakage of the LED 36a and light leakage to an adjacent region (illumination optical path) without deteriorating the design.

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

Moreover, in the said embodiment, although demonstrated in the example which provides an escape part in the site | part with which LED36a and the reflector 42 (peripheral wall 50) overlap (overlap) in the irradiation direction of illumination light, as shown in FIG. The relief portion 80 may be provided at a portion where the LED 36a and the reflector 42 (peripheral wall 50) do not overlap (not overlap) in the illumination light irradiation direction.
In FIG. 10, the escape portion 80 is formed such that both L1 and L2 are equal to or greater than a predetermined distance, similar to the escape portion 70 (see FIG. 8) described above.
In the description using FIG. 10 and subsequent drawings, the same reference numerals are given to the same members as those in the above-described embodiment, and the description thereof is omitted.

  Moreover, although the said embodiment demonstrated the example which forms an escape part so that both L1 and L2 may become more than predetermined distance, this invention is not limited to this. For example, the relief portion may be formed so that L1 is equal to or greater than the first predetermined distance and L2 is equal to or greater than 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 errors, assembly errors, 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 errors and assembly errors). On the other hand, the value of L2 varies depending not only on the relationship between the reflector 42 and the light source substrate but also on the relationship with the base member 40 to which the light source substrate 36 is attached. As described above, since the value of L2 is affected by the manufacturing error and assembly error of more members than L1, the range of the value to be changed tends to increase.
For this reason, the contact between the LED 36a and the reflector 42 can be more reliably prevented by setting the second predetermined distance to be larger than the first predetermined distance.

  The second predetermined distance is preferably set 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 or the portion where the foot or the foot is connected to the light source substrate (such as the portion to be soldered) is not contacted with the reflector. It is preferable to set the second predetermined distance.

Moreover, although the said embodiment demonstrated the example which forms an escape part by notching the surrounding wall 50 of a reflector, this invention is not limited to this. For example, as shown in FIG. 11, the escape portion 90 may be formed by bending the peripheral wall 85 of the reflector into a bowl shape.
In addition, when using a common illumination board with another model, depending on the design of the decorative panel, there may be a case where an unused LED (not emitting light) is generated. In such a case, as shown in FIG. 12, the escape portion 100 may be formed so as to surround the LED 36a that is not used.

  In the above-described embodiment, an example in which the present invention is applied to a slot machine as a gaming machine has been described. However, the present invention may be applied to a gaming machine other than a slot machine, such as a pachinko machine.
