The light emitted from the light emitting element is reflected in a predetermined direction so as to be impossible, and then propagated to the light emitting surface of the push button holder.
Hereinafter, the slot machine according to the present embodiment will be described in detail.

  As shown in FIGS. 1 and 2, the slot machine 1 of the present embodiment bets from the number of medals actually inserted from the medal slot 2 (for example, three), or from credit medals stored internally. When the button 2a is operated, the game can be started according to the number of medals inserted in the signal format (for example, 3). When the start lever 3 is operated (starting operation) in this state, the plurality of reels 4 When (4a to 4c) starts rotating and the operation button 21 (21a to 21c) of the stop switch device 10 corresponding to each reel 4 (4a to 4c) is depressed, the operation timing of the start lever 3 The reels 4 (4a to 4c) are controlled to stop at a combination of symbols corresponding to the lottery result of the lottery process performed in, and a prize is awarded based on the stopped symbol combination. Presence is determined, that medals are paid out from the medal payout device 5 in accordance with the determination result, and a feasible structure of ordinary slot machine game.

In the slot machine 1 capable of realizing such a slot machine game, a stop switch device 10 that stops the rotation of each reel 4 (4a to 4c) is a front door that constitutes the main body of the slot machine 1 as an operation switch device. It is provided in the middle of the front surface of 1a.
The stop switch device 10 is provided with operation buttons 21 (21a to 21c) that are pressed by a player. When these operation buttons 21 (21a to 21c) are pressed, this operation is performed by the main control unit. 6 is detected, and control to stop the rotation of each reel 4 (4a to 4c) is performed.

In the stop switch device 10, a push button holder 23 that houses the operation button 21 movably in the operation direction, and a light emitting element 32 that is provided behind the push button holder 23 and illuminates the push button holder 23 are arranged. When the light emitting element 32 is turned on and the push button holder 23 is illuminated, when the operation button 21 is viewed from the front of the operation surface 211, a lighting unit that is a front exposed surface of the push button holder 23 positioned around the operation surface 211. 236 shines brightly.
However, since the push button holder 23 is formed of a transparent or translucent member, when the push button holder 23 is viewed from the front of the lighting unit 236, the light emitting element 32 can be seen through the lighting unit 236. There was a factor that reduced the decoration effect and the production effect.

Thereby, the light emitting element 32 can be made invisible through the push button holder 23, and the lighting unit 236 can be turned on while suppressing a decrease in the decoration effect and the production effect.
Hereinafter, the stop switch device 10 of the present embodiment will be described with reference to FIGS.

[Stop switch device]
As shown in these drawings, the stop switch device 10 can move a plurality of operation buttons 21 (21a to 21c) pressed by the player and the operation buttons 21 (21a to 21c) in the pressing direction. The push button holder 23 to be accommodated, the translucent color plate 24 disposed on the back side of the push button holder 23, the reflection member 25 disposed inside the push button holder 23, and the push button holder 23 from the inside of the reflection member 25. 4 includes a push button switch unit 20 (20a to 20c) constituted by a hook-shaped grounding bearing 26 mounted over the outside. Further, as shown in FIG. 4, the front cover 11, the decorative plate 15, A casing 12, a control unit 30, a lid member 13, and the like are provided.
As for the operation buttons 21 (21a to 21c), those having a plurality of components having the same structure are provided with different identifiers (a, b, c). While clearly indicating that there is a function and structure common to these separate components, the identifier is omitted as appropriate.
Here, the structure of each part constituting the stop switch device 10 will be described first, and then the features of the present invention will be described.

  The operation button 21 is a movable part that can accept a pressing operation. As shown in FIG. 6 and the like, the operation button 21 includes a disk-shaped operation receiving part 212 having an operation surface 211 that directly receives a pressing operation by a player, A cylindrical portion (for example, a round bar with a small diameter) that protrudes from the central portion of one circular surface (back side surface) that is the operation receiving portion 212 and extends orthogonally outward. The movable member has a substantially T-shape when viewed from the side.

The operation button 21 can be formed using, for example, a conductive material. As the conductive material, for example, a metal such as iron can be selected.
Here, since the operation button 21 made of iron has a certain weight, when the operation button 21 is pressed, a stress opposite to the pressing is applied to the operated hand, and the player Can feel that they have operated.
Further, the weight of the operation button 21 is applied in the direction of gravity, and a stress from the operation button 21 and a restoring force of the spring 22 that urges the operation button 21 from the back are applied to the operated hand. It is like that. However, since these stresses and restoring forces are not so great, even if the player operates the operation button 21 many times, the operated hand hardly feels fatigue.

The push button holder 23 is a storage member that accommodates the operation button 21 so as to be movable in the pressing direction, and uses a transparent or translucent material (for example, ABS (acrylonitrile, butadiene, styrene copolymer synthetic resin), etc.). It is formed into a thick cylindrical shape.
With respect to the push button holder 23, the operation button 21 is inserted into the front opening 232 that is one cylindrical opening, and a disk-like shape is formed on the back 233 in which the rear opening 234 that is the other opening is formed. A translucent color plate 24 is overlaid.

  The translucent color plate 24 is a plate-like colored member made of a synthetic resin colored in a predetermined color, and is formed of a transparent or translucent material. The translucent color plate 24 is formed in the same circular shape as the outer shape of the back surface 233 of the push button holder 23, and the circular diameter of the translucent color plate 24 is equal to the diameter of the back surface 233 of the push button holder 23. It is almost the same length. For this reason, when the translucent color plate 24 is superimposed on the back surface 233 of the push button holder 23 so that one circular surface of the translucent color plate 24 contacts the back surface 233 of the push button holder 23, the translucent color plate The outer periphery of 24 and the outer periphery of the back surface 233 of the push button holder 23 are arranged so as to coincide with each other.

A through hole 241 is formed in the center of the circular surface of the translucent color plate 24 so as to penetrate from one circular surface to the other circular surface. A cylindrical reflecting member 25 is formed in the through hole 241. Inserted.
The reflecting member 25 is a reflecting portion of the present invention formed of an opaque material, and has a main body portion 251 formed in a cylindrical shape. A convex portion 252 projecting toward is formed. When the reflective member 25 is fitted into the through hole 241 of the translucent color plate 24, the opening side of the reflective member 25 on which the convex portion 252 is not formed is inserted into the through hole 241 of the translucent color plate 24. Then, the main body 251 of the reflecting member 25 is inserted into the through hole 241 of the translucent color plate 24, and the convex portion 252 of the reflecting member 25 is locked to the peripheral portion of the through hole 241 of the translucent color plate 24. Thus, the reflecting member 25 is inserted in a state of being positioned inside the through hole 241.

For the reflecting member 25 fitted in the through hole 241 of the translucent color plate 24, the bearing portion 261 of the grounding bearing 26 which is a bearing member having a cylindrical bearing portion 261 is the reflecting member 25. It is inserted into a hollow cylindrical shape.
The diameter of the outer periphery of the bearing portion 261 formed in the cylindrical shape of the grounding bearing 26 is substantially the same as the inner diameter of the cylindrical shape that is the reflecting member 25. For this reason, the bearing portion 261 of the grounding bearing 26 can be fitted into the hollow cylindrical shape of the reflecting member 25.

  Further, an L-shaped locked portion 262 projecting outward is formed on the periphery of one opening side of the bearing portion 261 of the grounding bearing 26, and protrudes from the back surface 233 of the push button holder 23. Locks to the hook-shaped locking portion 235 provided. Specifically, a hook-like locking portion 235 is protruded from the back surface 233 of the push button holder 23. The locking portion 235 is inserted through the through hole 241 of the translucent color plate 24 and exposed from the back surface of the translucent color plate 24. When the reflecting member 25 is inserted into the through hole 241 of the translucent color plate 24 and the bearing portion 261 of the grounding bearing 26 is inserted into the cylindrical shape of the reflecting member 25, the grounding bearing 26 is locked. The part 262 engages with the hook-shaped engaging part 235 exposed from the through hole 241 of the translucent color plate 24. Accordingly, the bearing portion 261 of the grounding bearing 26 is fixed in a state of being fitted into the cylindrical shape of the reflecting member 25 (see FIG. 5 (ii)).

  Further, the operation button 21 is inserted from the shaft portion 213 into the front side opening 232 of the push button holder 23 to which the translucent color plate 24, the reflection member 25, and the grounding bearing 26 are attached in this manner. The shaft portion 213 is slidably inserted into the cylindrical hollow portion of the bearing portion 261 of the grounding bearing 26 located inside the hollow of the push button holder 23. The end portion of the shaft portion 213 is exposed outward from the other opening of the bearing portion 261 of the grounding bearing 26, and the operation receiving portion 212 of the operation button 21 is provided on the front side opening 232 of the push button holder 23. Is inserted until it closes.

  In addition, when the operation button 21 is inserted into the front opening 232 of the push button holder 23, a coiled spring 22 that is an urging member is inserted around the shaft portion 213 of the operation button 21. One end surface of the spring 22 abuts on the translucent color plate 24 that closes the opening 234 on the back surface 233 side of the push button holder 23, and the other end surface abuts on the back surface of the operation receiving unit 212 of the operation button 21. . Thereby, the operation button 21 is urged by the spring 22 in the direction opposite to the operation direction when moving in the direction in which the operation is performed inside the push button holder 23. For this reason, when the force that has pushed the operation button 21 in the operation direction is released, the operation button 21 is pushed back to the position before the pressing operation is performed by the biasing by the spring 22.

Furthermore, the tip of the shaft portion 213 of the operation button 21 is exposed from the other opening of the bearing portion 261 of the ground bearing 26, but in the vicinity of the tip of the peripheral surface of the shaft portion 213, A groove portion 214 is formed in the groove portion 214, and an E-type retaining ring 27, for example, is press-fitted into the groove portion 214.
When the operation button 21 is pressed, the retaining ring 27 is separated from the other opening of the bearing portion 261 of the ground bearing 26. On the other hand, when the pressing operation of the operation button 21 is released, the retaining ring 27 comes into contact with the surface around the other opening of the bearing portion 261 of the ground bearing 26. Thus, when the operation button 21 is not pressed, the retaining ring 27 is urged in the direction opposite to the pressing direction by the urging by the spring 22, and the retaining ring 27 is the other of the bearing portions 261 of the grounding bearing 26. By contacting the surface around the opening, it is impossible to remove from the push button holder 23 and the grounding bearing 26.

When the operation button 21 is pressed as described above, the shaft portion 213 of the operation button 21 slides inside the hollow portion of the bearing portion 261 of the grounding bearing 26. Since the grounding bearing 26 is made of a synthetic resin such as POM (polyoxymethylene), the frictional resistance when the shaft portion 213 of the operation button 21 slides is very small. For this reason, the reciprocating operation when the operation button 21 is operated can be performed smoothly, and thereby the operability can be improved.
Moreover, since the grounding bearing 26 is formed using a conductive resin material such as POM, the fitting accuracy between the shaft portion 213 of the operation button 21 and the bearing portion 261 of the grounding bearing 26 is high. It has become. As a result, there is no backlash at the mating portion, the operability when the operation button 21 is pressed becomes smooth, and even if the player plays a game for a long time, it is unlikely that the operating hand will accumulate fatigue. It has become.

With such a structure, the operation button 21, the spring 22, the push button holder 23, the translucent color plate 24, the reflecting member 25, the grounding bearing 26 and the retaining ring 27 are combined with each other so as to be integrated into a unit. Thus, it is configured as one push button switch unit 20 (see FIGS. 5 (i) and (ii)).

Specifically, two first light emitting elements 321 are arranged above the propagation path (optical axis) of light emitted from the light projecting element 311, and one first light emitting element 321 is arranged below.
Further, the diameter of the circle in which the first light emitting element 321 is arranged at the center and the center between the light projecting element 311 and the light receiving element 312 is the same as or close to the diameter of the lighting part 236 of the push button holder 23. ing.

Further, when the substrate 33 on which the light projecting element 311 and the like are mounted is housed in the unit case 35, the unitized control unit 30 is fitted into the mounting recess 132 formed on the inner side surface 131 of the lid member 13. Is done. The mounting recess 132 is a portion that is recessed in the inner surface 131 of the lid member 13 in a shape that is substantially the same as the outer peripheral shape of the unit case 35 of the control unit 30. In the control unit 30 attached to the attachment recess 132, the rectangular cylindrical portion 353 and the cylindrical portion 354 of the unit case 35 are extended from the inner surface 131 of the lid member 13 in the orthogonal direction.
When the lid member 13 to which the control unit 30 is attached in this way is attached to the opening 124 of the back surface 123 of the casing 12 and the push button switch unit 20 is accommodated in the recess 121 of the casing 12, the cylindrical portion 354 of the control unit 30. The lighting part 236 of the push button holder 23 is positioned in front of the extending direction of the cylindrical part 354 corresponding to the first light emitting element 321.
In such a configuration, the light emitted from the first light emitting element 321 propagates through the hollow interior of the cylindrical portion 354, propagates in the extending direction of the cylindrical portion 354, and passes through the lid member 37. The light passes through the inside of the push button holder 23 and propagates from the back to the lighting direction of the lighting portion 236 of the push button holder 23.

In the control unit 30, a connector 34 is disposed on the back surface 332 of the substrate 33 (the surface opposite to the mounting surface 331 on which the light projecting element 311 and the like are erected).
The connector 34 is connected to each of the light projecting element 311, the light receiving element 312, and the light emitting element 32 through the substrate 33 while being attached to the back surface 332 of the substrate 33, and from the outside, the light projecting element A wiring for passing a current through 311, a wiring for passing a detection signal output from the light receiving element 312, and a wiring for causing the light emitting element 32 to emit light are connected.
The connector 34 is inserted into an opening 361 formed in the center of the lid portion 36 when the substrate 33 is accommodated in the unit case 35 and the lid portion 36 is closed by the opening of the back surface 356 of the unit case 35. It is exposed to the outside.

  Further, when the control unit 30 is attached to the attachment recess 132 provided in the inner surface 131 of the lid member 13, the connector 34 exposed to the outside from the opening 361 of the lid portion 36 of the control unit 30 is connected to the lid member 13. Is inserted into an insertion hole 133 formed in the concave bottom of the mounting recess 132. While inserting the connector 34 into the insertion hole 133, the control unit 30 is fitted into the mounting recess 132, and the hook-shaped portion 134 formed on the side of the mounting recess 132 is locked to the unit case 35 of the control unit 30. As a result, the control unit 30 can be fixed to the mounting recess 132.

  Further, one or more circular screw insertion holes 135 for inserting the screws 141 are formed at predetermined positions of the lid member 13, and the lid member is located at a position where the opening 124 of the back surface 123 of the casing 12 is closed. 13 is inserted, the screw 141 is inserted into the screw insertion hole 135 of the lid member 13, the screw 141 is inserted into the hole formed in the bottom of the bottomed hole 1221 of the casing 12, and the bottomed hole is further inserted. The lid member 13 can be screwed and fixed to the back surface 123 of the casing 12 by being screwed into a female screw (not shown) formed on the guide boss 112 of the front cover 11 fitted to 1221. Furthermore, the front cover 11 can be screwed and fixed to the front surface 122 of the casing 12.

Further, when the lid member 13 to which the control unit 30 is attached is attached to the opening 124 of the back surface 123 of the casing 12 and the push button switch unit 20 is accommodated in the recess 121 of the casing 12, the first light emitting element 321 in the control unit 30. The casing 12 (the bottom 125 of the recess 121) and the translucent color plate 24 are located between the push button switch unit 20 and the push button holder 23. The bottom 125 of the recess 121 of the casing 12 Since the light passage opening 126 is formed at a portion that intersects the path of light propagation from the one light emitting element 321 toward the push button holder 23, the light can pass therethrough. Since it is formed of a transparent or translucent material, the light can be transmitted. Therefore, the light emitted from the first light emitting element 321 passes through the light passage opening 126 of the casing 12, passes through the translucent color plate 24, and can illuminate the push button holder 23.
The light emitted from the second light emitting element 322 passes through the decorative lighting opening 1261 (see FIG. 8) formed in the bottom of the concave portion formed in the front surface 122 of the casing 12, and passes through the decorative plate 15. A predetermined location can be illuminated.

  Further, in the concave portion 121 of the casing 12, a shaft portion opening 127 is formed in the central portion of the bottom portion 125 of the concave portion 121, and the operation button 21 of the push button switch unit 20 fitted in the concave portion 121 is pressed. When this occurs, the shaft portion 213 of the operation button 21 passes through the shaft portion opening 127. In addition, the sensor 31 for detecting the operation of the operation button 21 is mounted on the substrate 33 and is housed in the unit case 35, and the translucent color of the push button switch unit 20 is passed through the bottom 125 of the recess 121. It is arranged opposite to the plate 24. Thereby, the end portion of the shaft portion 213 of the operation button 21 protruding from the center of the translucent color plate 24 opens the shaft portion opening 127 of the concave portion 121 of the casing 12 when the operation button 21 is pressed. Thus, the light can enter between the light projecting element 311 and the light receiving element 312 in the sensor 31.

Up to this point, the configuration of the stop switch device 10 of the present embodiment has been described. However, the stop switch device 10 having the above configuration has the following characteristics.
(1) Formation of the groove 238 in the push button holder 23 and arrangement of the reflecting member 25 (2) The lighting portion 236 of the push button holder 23 emits light uniformly uniformly by irregular reflection on the surface of the reflecting member 25. (3) Translucent Illumination of a specific color by the color plate 24 (4) Countermeasures against fraud (5) Easy assembly These features will be described in the following order.

(1) Formation of groove 238 in push button holder 23 and arrangement of reflecting member 25 In stop switch device 10 of the present embodiment, as shown in FIGS. 7 and 10, outer peripheral surface 237 of push button holder 23 having a cylindrical shape. The groove 238 is recessed in a V shape along the circumferential direction. As shown in FIG. 10, a cylindrical reflecting member 25 is disposed around the shaft portion 213 of the operation button 21.
With such a configuration, the light emitted from the first light emitting element 321 does not propagate linearly and directly reaches the lighting portion 236 of the push button holder 23, but the light does not reach the groove portion of the push button holder 23. The light is reflected by 238, reflected by the surface of the reflecting member 25, and after changing the propagation path of the light in this way, this light reaches the lighting part 236 of the push button holder 23. Thus, when the push button holder 23 is viewed from the front, the first light emitting element 321 cannot be visually recognized through the lighting portion 236, and the lighting portion 236 can be turned on.
The structure of the groove portion 238 of the push button holder 23 and the reflecting member 25, which is a main configuration for realizing such a structure, will be described in more detail.

The groove portion 238 is a portion that is recessed in a V shape from the outer peripheral surface 237 of the push button holder 23 toward the inside of the push button holder 23.
Further, the groove 238 is formed between the incident portion 2331 positioned around the back side opening 234 and the lighting portion 236 positioned around the front side opening 232 in the push button holder 23 in which the groove 238 is formed. ing. In other words, when the push button holder 23 in which the groove portion 238 is not formed is assumed, light emitted from the first light emitting element 321 enters the incident portion 2331 and propagates through the push button holder 23. The groove 238 is formed on the propagation path of the light when reaching the lighting part 236.

Further, the depth of the groove portion 238 (the depth from the outer peripheral surface 237 of the push button holder 23 to the deep portion of the groove portion 238) is the width of the lighting portion 236 of the push button holder 23 (the outer periphery and inner periphery of the annular lighting portion 236). Longer than the interval). That is, when the push button holder 23 is viewed from the front surface 231 side of the lighting portion 236, the diameter of the outer peripheral surface 237 of the push button holder 23 is substantially the same as or larger than the outer diameter of the annular lighting portion 236. The diameter of the deep part of the groove part 238 is substantially the same as or shorter than the diameter of the inner periphery of the lighting part 236. In other words, when the push button holder 23 is viewed from the front surface 231 side, the outer peripheral surface 237 of the push button holder 23 is substantially at the same position as the outer periphery of the lighting portion 236 or is located outside the outer periphery. Further, the deep part of the groove part 238 is located at substantially the same position as the inner periphery of the lighting part 236, or is located further inside.
For this reason, when the push button holder 23 is viewed from the front surface 231 side, the entire lighting portion 236 overlaps the groove portion 238.

  The push button holder 23 in which the groove 238 having such a shape is formed is incorporated as a part of the push button switch unit 20, accommodated in the recess 121 of the casing 12, and the control unit 30 disposed on the back surface 123 side of the casing 12. The light emitted from the first light emitting element 321 is illuminated.

The light propagation path at this time follows a path as shown in FIG.
That is, the light radiated from the first light emitting element 321 propagates through the hollow interior of the cylindrical portion 354 of the unit case 35, passes through the lid member 37 fitted to the upper surface portion 355 of the cylindrical portion 354, and the casing 12. The portion passing through the light passage opening 126 and passing through the translucent color plate 24 and located around the back side opening 234 in the push button holder 23 (the portion other than the back side opening 234 in the back side 233 of the push button holder 23) Is incident on the incident portion 2331.
The light incident on the incident portion 2331 propagates inside the push button holder 23 and constitutes one inclined surface of the groove portion 238 (an inclined surface located on the back surface 233 side of the push button holder 23). When reaching the first inclined surface 2381), the light is reflected by the first inclined surface 2381 and propagates toward the inner side surface 239 of the push button holder 23. Then, the light is refracted with the inner side surface 239 as an interface, and propagates toward the surface of the reflecting member 25 in the space between the inner side surface 239 and the reflecting member 25.

The reflecting member 25 is a member constituting the second reflecting portion of the present invention, and is formed of an opaque material and is formed of a color having a high reflection efficiency, for example, a white material. Thereby, the reflecting member 25 reflects most of the light incident on the surface.
The light that is refracted with the inner surface 239 of the push button holder 23 as an interface and propagates through the space between the inner surface 239 of the push button holder 23 and the reflecting member 25 is reflected on the surface of the reflecting member 25, so Reach side 239. The light is refracted with the inner side surface 239 as an interface and propagates through the inside of the push button holder 23, and is the other slope of the groove portion 238 (the slope located on the front surface 231 side of the push button holder 23). When reaching the second inclined surface 2382) constituting the reflecting portion, the light is reflected by the second inclined surface 2382 to reach the lighting portion 236, illuminates the lighting portion 236, and turns on the lighting portion 236.
Thus, since the light reflected by the reflecting member 25 reaches the lighting part 236 of the push button holder 23 indirectly (or directly depending on the reflected direction), the reflecting member 25 pushes the incident light into the push button. It is a member that reflects in a direction that can reach the lighting part 236 of the holder 23.

In this way, the light emitted from the first light emitting element 321 is not linearly propagated toward the lighting part 236 and illuminates the lighting part 236, but on the first inclined surface 2381 of the groove part 238. The light is reflected, refracted at the inner surface 239 as an interface, reflected by the reflecting member 25, refracted at the inner surface 239 as an interface, and reflected by the second inclined surface 2382 of the groove 238, and then the lighting unit 236 is illuminated.
That is, the propagation path until the light emitted from the first light emitting element 321 reaches the lighting unit 236 is not a straight line, but follows a path whose propagation direction has been changed by reflection or refraction. From this, when the lighting part 236 is viewed from the front, the light emitted from the first light emitting element 321 does not directly reach the visually recognized eyes. It is invisible directly.

The principle that the first light emitting element 321 is not visible through the lighting unit 236 will be further described. When a human visually recognizes an object, the light reflected by the surface of the object is incident on his / her eyes, and an image of the object is formed on the retina in the eye, whereby the object is detected. Can be visually recognized. In the stop switch device 10 of the present embodiment, since the groove 238 is formed on the propagation path of the light emitted from the first light emitting element 321, the light emitted from the first light emitting element 321 is directly transmitted to humans. Does not reach the eyes. Even when the first light emitting element 321 is not lit, the light reflected by the first light emitting element 321 does not directly reach the human eye. For this reason, when a human sees the lighting part 236, the person cannot see the first light emitting element 321 through the lighting part 236.
In addition, when the push button holder 23 is viewed from the front surface 231 side, the entire lighting portion 236 overlaps the groove portion 238, so that the light emitted from the first light emitting element 321 or the light reflected by the first light emitting element 321 is reflected. Among them, since all of the light that tries to reach the lighting part 236 is reflected by the groove part 238, the first light emitting element 321 cannot be seen through the lighting part 236. Thereby, the decorative beauty of the stop switch device 10 can be maintained.

The light reflected by the groove portion 238 of the push button holder 23 reaches the reflecting member 25 after being refracted with the inner side surface 239 as an interface. However, the light is diffusely reflected and diffused on the surface of the reflecting member 25.
The reason why light is irregularly reflected on the surface of the reflecting member 25 is that the surface of the reflecting member 25 is not mirror-finished, and fine irregularities that cannot be seen by humans are randomly formed on the surface. Secondly, since the reflecting member 25 has a cylindrical shape, the surface shape of the reflecting member 25 is a curved surface.
For these reasons, light is irregularly reflected on the surface of the reflecting member 25. The light reflected by the surface of the reflecting member 25 in this way enters the inner surface 239 of the push button holder 23 and is reflected by the second inclined surface 2382 of the groove portion 238. Since the illumination is performed at an angle, the lighting unit 236 can emit light uniformly, and uneven brightness in the lighting unit 236 can be suppressed.

  In the cross-sectional view of the pushbutton switch unit 20 shown in FIG. 10, only one propagation path of light emitted from the first light emitting element 321 is illustrated, but the actual propagation path of light is the illustrated path. Not specified. For example, since light is emitted radially from the first light emitting element 321, the first inclined surface 2381 of the groove 238 of the push button holder 23 reflects the emitted light on the entire first inclined surface 2381. . In addition, since the incident light is diffusely reflected and diffused on the surface of the reflecting member 25, the diffused light is incident on almost the entire inner surface 239 of the push button holder 23. Of the light incident on the inner surface 239 in this way, the light that has reached the second inclined surface 2382 of the groove 238 is reflected by the second inclined surface 2382 and reaches the lighting unit 236, and this lighting unit 236 emits light uniformly.

The reflecting member 25 can be formed using a material capable of reflecting incident light.
As a material capable of reflecting incident light, a predetermined synthetic resin having a high reflectance can be used. Specific examples of the synthetic resin include, for example, polyethylene (PE), polypropylene (PP), polymethylpentene (PMP), polybutene-1 (PB-1), butadiene resin (BDR), and ethylene-tetracyclododecene copolymer. (E / TD), polystyrene (PS), AS resin (acrylonitrile / styrene resin), ABS resin (acrylonitrile / butadiene / styrene resin), polyphenylene ether (PPE), polyacrylonitrile (PAN), fluororesin (FR), poly Methacryl styrene (MS), methacrylic resin (PMMA), polyamide (PA), polyethylene terephthalate (PET), polycarbonate (PC), polyvinyl alcohol (PVA), polyacetal (POM), polybutylene terephthalate (PBT) , Polyallylsulfone (PASF), polyarylate (PAR), hydroxybenzoic acid polyester (HBP), polyetherimide (PEI), polycyclohexylenedimethylene terephthalate (PCT), polyethylene naphthalate (PEN), polyester carbonate ( PPC), polylactic acid (PLA), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polyvinyl acetate (vinyl acetate resin), phenol resin (phenol-formaldehyde resin), urea resin, melamine resin, unsaturated polyester And so on.
The reflecting member 25 can be formed in a color that can reflect light. Examples of the color capable of reflecting light include white or a color close thereto.

In FIG. 10, the reflecting member 25 is provided around the shaft portion 213 of the operation button 21. However, instead of the structure in which the reflecting member 25 is provided, for example, as shown in FIG. The coating portion 28 such as a paint having a function of reflecting incident light can be applied to the surface of the 26 bearing portions 261 as a reflection portion.
According to this configuration, the light refracted by using the inner surface 239 of the push button holder 23 as an interface is reflected by the coating portion 28 and reaches the inner surface 239 of the push button holder 23, and is refracted by using the inner surface 239 as an interface. After being reflected by the second inclined surface 2382 of 238, the lighting part 236 is illuminated. That is, the coating unit 28 can reflect the incident light in a direction that can reach the lighting unit 236 of the push button holder 23, similarly to the reflection member 25.
Even in this case, since the light emitted from the first light emitting element 321 reaches the lighting unit 236 while changing the propagation direction by reflection or refraction, when the lighting unit 236 is viewed from the front, the first The light emitting element 321 is not visible.

The coating portion 28 can be formed of, for example, a material that can reflect incident light. Specifically, for example, “water-based paint composition” disclosed in JP2012-092289A, “highly reflective paint and coated metal plate” disclosed in JP2008-266652, and the like can be used. .
Moreover, the coating part 28 can be formed in the color which can reflect light. Examples of the color capable of reflecting light include white or a color close thereto.

Thus, by providing the coating portion 28 instead of the reflecting member 25, the reflecting member 25 can be omitted, and the bearing portion 261 of the grounding bearing 26 can have a light reflecting function.
Note that the grounding bearing 26 is assumed to use POM, which is a conductive material, as its material. Since this POM is generally a black material, it has a low reflectance. However, by providing the coating portion 28 described above on the surface of the bearing portion 261 of the grounding bearing 26, the bearing portion 261 of the grounding bearing 26 can have a light reflecting function.

Further, in FIG. 7 and the like, the groove portion 238 has an angle formed by the first inclined surface 2381 and the second inclined surface 2382 of about 90 °, but this angle is not limited to 90 °, and the light emission The position of the element 32, the thickness of the push button holder 23, the width of the lighting part 236, and the like can be changed as appropriate.
Moreover, in FIG. 7 and the like, the length of the first inclined surface 2381 in the inclined direction and the length of the second inclined surface 2382 in the inclined direction are the same, but these lengths are the same length. However, the present invention is not limited to this, and can be appropriately changed according to the various requirements described above.

Examples of shapes that can be formed as the groove 238 are shown in FIGS.
FIG. 12I is an angle formed by the incident direction c1 of light emitted from the first light emitting element 321 and incident on the first inclined surface 2381 of the groove 238, and the normal direction n1 of the first inclined surface 2381. The angle of the first inclined surface 2381 is set so that the incident angle θ1 is larger than 45 °.
When the light emitted from the first light emitting element 321 is incident on the incident portion 2331 of the push button holder 23, it is reflected by the first inclined surface 2381 of the groove portion 238, but when the incident angle θ 1 on the first inclined surface 2381 is small. Since a part of the light emitted from the first light emitting element 321 does not reach the reflecting member 25 and the amount of light reaching the lighting part 236 is reduced, the lighting part 236 cannot be lit brightly.
Therefore, the angle of the first inclined surface 2381 is set so that the incident angle θ1 at the first inclined surface 2381 is large. Thereby, most of the light emitted from the first light emitting element 321 can reach the reflecting member 25, and the lighting unit 236 can be lit brightly.

FIG. 12 (ii) shows an incident angle which is an angle formed by the incident direction c2 of light incident on the second inclined surface 2382 of the groove 238 after being reflected by the reflecting member 25 and the normal direction n2 of the second inclined surface 2382. The angle of the second inclined surface 2382 is set so that θ2 is larger than 45 °.
When the light reflected by the reflecting member 25 is refracted by the inner surface 239 of the push button holder 23 and propagates through the push button holder 23, it is reflected by the second inclined surface 2382 of the groove 238. When θ2 is small, a part of the light reflected by the second inclined surface 2382 does not reach the lighting part 236, and the amount of light reaching the lighting part 236 decreases, so that the lighting part 236 can be lit brightly. become unable.
Therefore, by setting the angle of the second inclined surface 2382 so that the incident angle θ2 at the second inclined surface 2382 becomes large, most of the light reflected by the second inclined surface 2382 can reach the lighting unit 236. The lighting part 236 can be lit brightly.

In FIG. 12 (iii), the angle of the first inclined surface 2381 is set so that the incident angle θ1 at the first inclined surface 2381 is increased, and the second inclined angle is set so that the incident angle θ2 at the second inclined surface 2382 is increased. The angle of the surface 2382 is set.
Thereby, since the light quantity which reaches the lighting part 236 can be increased, the lighting part 236 can be lit brightly.

In FIG. 12 (iv), the angle of the first inclined surface 2381 is set so that the incident angle θ1 on the first inclined surface 2381 is increased, and the second inclined surface 2382 is omitted.
The surface of the reflecting member 25 diffuses incident light. Due to the structure of the push button holder 23, the irregularly reflected light does not reach the second inclined surface 2382 but directly reaches the lighting part 236, or there is an outer peripheral surface 237 of the push button holder 23 (lit with the second inclined surface 2382). Some of them are reflected by the outer peripheral surface 237) with the portion 236 and reach the lighting portion 236.
From such a situation, the second inclined surface 2382 reflects only a part of the light irregularly reflected on the surface of the reflecting member 25 to reach the lighting part 236.
Therefore, the groove 238 has a structure in which only the first inclined surface 2381 is provided and the second inclined surface 2382 is omitted. Even in this case, the light irregularly reflected on the surface of the reflecting member 25 can reach the lighting unit 236, and the lighting unit 236 can be lit brightly.
However, since the second inclined surface 2382 is an inclined surface for efficiently allowing the light irregularly reflected on the surface of the reflecting member 25 to reach the lighting unit 236, the second inclined surface 2382 is formed as the structure of the groove portion 238. It is desirable to provide a structure.

FIG. 12 (v) is provided with a plurality of grooves 238 or second inclined surfaces 2382.
Even in such a shape, the amount of light reaching the lighting part 236 can be increased, so that the lighting part 236 can be lit brightly.
In FIG. 12 (v), since a plurality of V-shaped grooves are formed, a plurality of inclined surfaces (four in FIG. 12) are formed. Only the inclined surface (only the inclined surface located closest to the back surface 233 of the push button holder 23 among the plurality of inclined surfaces) is the first inclined surface 2381, and the other inclined surfaces are the second inclined surfaces 2382. This is because the light emitted from the first light emitting element 321 reflects only the bottom inclined surface, and the other inclined surfaces reflect the light irregularly reflected on the surface of the reflecting member 25. .

In FIG. 12 (vi), the cross-sectional shape of the groove 238 is not a V shape but a trapezoid. That is, the groove portion 238 can have a shape in which the first inclined surface 2381 and the second inclined surface 2382 are separated from each other.
Even in such a shape, since the light emitted from the first light emitting element 321 can be reflected or refracted to reach the lighting unit 236, when the push button holder 23 is viewed from the front, the light passing through the lighting unit 236. The first light emitting element 321 becomes invisible. Further, since the amount of light reaching the lighting unit 236 can be increased, the lighting unit 236 can be lit brightly.

Further, in the push button holder 23 shown in FIGS. 7 and 12, the groove 238 is formed in a groove shape, and a space is formed between the first inclined surface 2381 and the second inclined surface 2382.
In this case, on the first inclined surface 2381, not all of the light emitted from the first light emitting element 321 is reflected, but there is also light propagating in the space. Further, on the second inclined surface 2382, not all of the light reflected by the reflecting member 25 or the coating portion 28 and incident on the inner surface 239 of the push button holder 23 is reflected, but there is also light propagating in the space. To do.
Therefore, in order to reduce the light propagating through the space and increase the reflection efficiency at the first inclined surface 2381 and the second inclined surface 2382, as shown in FIG. 13, a filling member 2383 is provided in the space. be able to.
For the filling member 2383, for example, a material having high surface reflectance can be used. An opaque material or a white material can also be used as the filling member 2383. This eliminates the propagation of light in the space between the first inclined surface 2381 and the second inclined surface 2382, so that the reflection efficiency in the groove 238 can be increased.

(2) The lighting portion 236 of the push button holder 23 emits light uniformly as a whole by irregular reflection on the surface of the reflection member 25. Also described in “(1) Formation of the groove 238 in the push button holder 23 and arrangement of the reflection member 25”. As described above, in the stop switch device 10 according to the present embodiment, the light emitted from the first light emitting element 321 is diffused when reflected by the groove 238 or when reflected by the reflecting member 25, so Can be made to emit light.
This effect can be cited as a difference from Patent Document 1.
In the switch device described in Patent Document 1, a bullet-type LED is used as a light-emitting element, and the normal direction of the top of the bullet-type is not the direction toward the lighting portion of the push button holder, but the shaft portion of the operation button. The direction is suitable for. For this reason, in this switch apparatus, when the lighting part of a pushbutton holder is seen from the front, the side surface of a bullet-type LED can be seen. Then, when the lighting part of the push button holder is viewed from the front, light is emitted in the vicinity of the top of the shell type, so that the part of the lighting part emits light, but in the vicinity of the end part of the shell type, Since no light is emitted, the portion of the lighting part becomes dark. Thereby, in the lighting part, the brightness is uneven.

On the other hand, in the stop switch device 10 of the present invention, it is assumed that a chip type LED is used as the light emitting element 32, and the orthogonal direction of the light emitting surface of the chip type LED is the lighting of the push button holder 23. The direction is toward the portion 236.
The light emitted from the first light emitting element 321 is diffused when reflected by the groove portion 238 or when reflected by the reflecting member 25, so that the lighting portion 236 can emit light uniformly, and the brightness is improved. Unevenness can be suppressed.

(3) Illumination of specific color by translucent color plate 24 In the stop switch device 10 of the present embodiment, in order to cause the illumination part 236 of the push button holder 23 located around the operation button 21 to emit light in a specific color, The translucent color plate 24 colored with the specific color is arranged on the propagation path of the light emitted from the one light emitting element 321.

The light emitted from the first light emitting element 321 follows the propagation path shown in FIG. That is, the light radiated from the first light emitting element 321 propagates through the hollow interior of the cylindrical portion 354 of the unit case 35, passes through the light passage opening 126 of the casing 12, passes through the translucent color plate 24, The light enters the incident portion 2331 of the push button holder 23.
Thus, since the light emitted from the first light emitting element 321 passes through the translucent color plate 24, the lighting portion 236 of the push button holder 23 can emit light with the color of the translucent color plate 24, A light emission effect by color light is possible.

Further, since the color can be determined by the color of the translucent color plate 24, an inexpensive white LED can be used for the first light emitting element 321 itself that emits light. Thereby, since it is not necessary to use expensive color LED as the 1st light emitting element 321, the high cost can be suppressed.
Note that the color of the translucent color plate 24 can be arbitrarily determined in consideration of the effect of color development such as red, blue, and yellow.
Further, the color of the translucent color plate 24 can be only one color, or can be a plurality of colors. In the case of a plurality of colors, the disc-shaped translucent color plate 24 can be color-coded for each angle.
Furthermore, since the translucent color plate 24 is an independent member, the light emission color of the lighting portion 236 of the push button holder 23 can be freely changed to a desired color by replacing the translucent color plate 24.

(4) Countermeasures against fraud The stop switch device 10 according to the present embodiment is a device attached to the slot machine 1, and the fraudulent act that illegally pays out gaming media such as medals to the slot machine 1. May occur.
Among them, the following illegal acts are intended for the stop switch device 10. For example, a small appliance capable of generating static electricity, specifically, an electronic lighter or the like is directed toward the operation button 21 to generate static electricity and apply a voltage to the substrate 33 disposed inside the stop switch device 10. A large discharge current is supplied, and further, a discharge current is supplied to the main control board and the sub control board through the harness connected to the board 33 to induce malfunctions of the main control board, etc. There is a fraudulent act of letting you pay. Here, the malfunction of the main control board or the like may be, for example, that the control program is operated on the assumption that the present game state is higher than usual even though the present game state is not a game state in which the yield rate varies. In some cases, the credit card is not full, but it is misunderstood as being full. It was a big problem.

Therefore, the stop switch device 10 of the present embodiment has a configuration corresponding to such an illegal act using static electricity. There are the following two specific configurations.
(4-1) Grounding of the pushbutton switch unit 20 (4-2) Unitization of the light emitting element 32 and the sensor 31 These configurations will be described in order.

(4-1) Grounding of the pushbutton switch unit 20 In the stop switch device 10 of the present embodiment, the grounding bearing 26 of the pushbutton switch unit 20 has an L-shape (bearing portion) outward from the side end of the bearing portion 261. The outer peripheral portion 263 of L-shape extending in the orthogonal direction from the extending end portion is projected from the side surface end portion of the H.261. Then, when the grounding bearing 26 having the circumscribed portion 263 is incorporated in the push button switch unit 20 and the push button switch unit 20 is accommodated in the recess 121 of the casing 12, the space between the recess 121 of the casing 12 and the upper surface (side portion 128). The circumscribed portion 263 is exposed from the notch portion 129 formed in the contact portion 129 and contacts the front door 1a of the slot machine 1 to be grounded. Accordingly, it is possible to prevent damage such as destruction of the substrate 33 caused by discharge current due to static electricity generated in the vicinity of the operation button 21 flowing to the substrate 33 provided in the casing 12.

This configuration and effect will be further described in detail.
The grounding bearing 26 of the pushbutton switch unit 20 is made of a conductive resin (for example, polyoxymethylene (POM)).
When assembling the push button switch unit 20, the translucent color plate 24 is overlaid on the back surface 233 of the push button holder 23, and the reflective member 25 is fitted into the through hole 241 of the translucent color plate 24. When the bearing portion 261 of the grounding bearing 26 is fitted, the circumscribed portion 263 of the grounding bearing 26 is positioned outside the outer peripheral surface 237 of the push button holder 23 (see FIGS. 5 (i) and (ii)). ).
Then, when the push button switch unit 20 constituted by these grounding bearings 26 and the like is inserted into the recess 121 of the casing 12, the circumscribed portion 263 of the grounding bearing 26 is orthogonal to the direction in which the operation button 21 is pressed. The circumscribed portion is formed so as to project in the direction (upward in FIGS. 3, 4, 10, etc.) and cut out from the inner surface of the recess 121 to the side portion 128 of the casing 12. It fits into the notch 129 which is an engaging part. At this time, a part of the circumscribed portion 263 protrudes outward from the cutout portion 129.

Further, when the stop switch device 10 is attached to the front door 1a of the gaming machine 1, the circumscribed portion 263 of the grounding bearing 26 contacts the front door 1a. Specifically, the structure is as follows.
A rectangular opening (not shown) is formed in the central portion of the front door 1a, and the stop switch device 10 is fitted into this opening. At this time, the stop switch device 10 is fitted from the front side of the front door 1a toward the opening thereof, and the rear surface 123 of the casing 12 and the opening thereof are disposed so as to face each other, and then the opening in this direction. Fitted. When the casing 12 is exposed on the back side of the front door 1a, a screw member (not shown) or the like is attached to the female screw of the boss 113 formed at the end of the front cover 11, and the front door 1a. The stop switch device 10 is screwed and fixed to the front door 1a by being screwed through the peripheral edge of the opening.
The stop switch device 10 is fitted into the opening of the front door 1a in such a procedure, but the peripheral edge of the opening of the front door 1a is plated with metal, and the stop switch device 10 A circumscribed portion 263 of the grounding bearing 26 exposed from the upper surface of the casing 12 contacts the metal plating. The metal plating is connected to a ground wire provided on the front door 1a or the casing 1b of the slot machine 1, and is thereby grounded. For this reason, when the circumscribed portion 263 comes into contact with the metal plating, the entire grounding bearing 26 in which the circumscribed portion 263 is formed is grounded.

By having such a structure, a discharge current based on static electricity generated in the vicinity of the operation button 21 is connected to the front door 1a or the housing 1b of the slot machine 1 via the circumscribed portion 263 of the grounding bearing 26. You can escape toward the ground wire.
For this reason, it is possible to prevent adverse effects such as the discharge current due to the static electricity flowing to the substrate 33 provided inside the stop switch device 10 to destroy the operation circuit.

  Further, not only the generation of static electricity due to fraud, but for example, when a player operates the operation button 21, the static electricity charged to the player enters between the operation button 21 and the push button holder 23. Things can happen. However, in this case as well, the circumscribed portion 263 of the grounding bearing 26 is reliably grounded, so that it is possible to avoid a situation in which a discharge current caused by static electricity flows to the operation circuit mounted on the substrate 33 and is destroyed.

(4-2) Unitization of light emitting element and sensor In the stop switch device 10 of the present embodiment, the sensor 31 and the like are housed in the unit case 35 and are inaccessible from the outside. Unauthorized acts targeting the stop switch device 10 can be effectively prevented.
For example, the substrate 33 on which the sensor 31 and the like are mounted is housed in the unit case 35 together with the sensor 31 and the like. Therefore, the unit case 35 is interposed between the gap between the casing 12 and the operation button 21 and the substrate 33, and the gap and the substrate 33 are not in communication with each other. That is, the board 33 is inaccessible from the gap between the casing 12 and the operation button 21. Therefore, when an illegal act of generating static electricity is performed outside the operation surface 211 or in the gap between the casing 12 and the operation button 21 using an electronic lighter or the like, the static electricity is shielded by the unit case 35 and the substrate 33 Can not reach. For this reason, the situation where a discharge current flows with the impact of the static electricity and the board | substrate 33 is destroyed can be prevented. Further, it is possible to avoid a situation in which a discharge current flows from the board 33 to the main control board and medals are illegally paid out.

  Further, in addition to using the electronic lighter described above, for example, the stop button 21 and the improper act of causing a discharge current to flow through the board 33 of the stop switch device 10 and the main control board in the slot machine 1 by generating static electricity. There is an illegal act of inserting a lead wire into the gap with the push button holder 23 and generating static electricity from the tip of the lead wire. However, even if an illegal act is performed using the lead wire in this way, the tip of the lead wire inserted from the gap between the casing 12 and the operation button 21 is not the rectangular cylindrical portion 353 or the cylindrical portion of the unit case 35. It always comes into contact with any one of 354 and cannot reach the substrate 33. Thus, it is possible to prevent the substrate 33 from being damaged due to the influence of static electricity generated from the tip of the lead wire. Further, it is possible to avoid a situation in which a discharge current flows from the board 33 to the main control board and medals are illegally paid out.

(5) Easy assembly Since the stop switch device 10 of the present embodiment has a relatively simple structure, it is easy to assemble.
For example, the push button switch unit 20 engages the operation button 21, the spring 22, the push button holder 23, and the grounding bearing 26 by combining each other in the axial direction, and presses the retaining ring 27 into the groove portion 214 of the operation button 21. The assembly is complete.
The stop switch device 10 houses the push button switch unit 20 in the recess 121 of the casing 12, the front cover 11 is attached to the front surface 122 of the casing 12, the control unit 30 is attached to the lid member 13, and the lid member Assembling is completed by attaching 13 to the back surface 123 of the casing 12.
Thus, since the stop switch device 10 is easy to assemble, the assembly work can be reduced.

As described above, according to the operation switch device and the gaming machine of the present embodiment, when the stop switch device is viewed from the front, the LED cannot be seen through the translucent body. Maintaining aesthetics.

However, this translucent body is formed of a transparent material, and the LED is provided in a side recess of the translucent body. For this reason, when the operation button side of the stop switch device is viewed from the front, the LED is visible through the exposed portion of the transparent light-transmitting body located around the operation button.
The translucent body has a function of decorating the stop switch device as well as a function of performing a light emission effect. For this reason, it is desirable that the exposed portion of the transparent body is uniformly decorated with a uniform color (white if white). However, when the LED can be seen through the translucent body, only this part appears to be a different color, so the uniformity of the color of the translucent body is impaired and the translucent body is visually recognized. When it looks bad. If it does so, the decoration function of the said translucent body cannot fully be exhibited, but there existed a problem that the external appearance of a stop switch apparatus would be spoiled.
Further, when the LED is lit, when the translucent body is viewed from the front, the portion where the LED is visible in the exposed portion of the translucent body shines brightest, and the brightness increases as the distance from the LED increases. It will fade out gradually. For this reason, the light emitting surface which is the exposed part of the transparent body does not emit light uniformly, and the brightness becomes non-uniform, resulting in a problem in the production effect.
According to the operation switch device of the present invention, it is possible to solve all or part of such problems that the conventional operation switch device should improve.
