Composed. In addition, the front side protrusion amount of the upper partition wall 242d is slightly suppressed as compared with the first left and right walls 242b and 242c. The first upper wall 242a, the first left wall 242b, the first right wall 242c, and the upper partition wall 242d are reflective surfaces including an inclined reflecting portion to which light from the first and second LEDs 231 and 232 can reach. In order to function, it is formed using a material capable of realizing an appropriate reflectance, or surface treatment such as surface coating or mirror finishing is performed.

  The second reflector portion 241b includes a lower partition wall 242e inclined upward from an appropriate upper position of the third and fourth LEDs 233 and 234, first left and right walls 242b and 242c, and third and fourth LEDs 233 and 234. The first lower wall 242f is inclined as appropriate from the lower position toward the front and is connected to the lower ends of the first left and right walls 242b and 242c. The front end of the lower partition wall 242e is continuous with the front end of the upper partition wall 242d. The lower partition wall 242e, the first left wall 242b, the first right wall 242c, and the first lower wall 242f are reflective surfaces including an inclined reflecting portion to which light from the third and fourth LEDs 231 and 232 can reach. In order to function as a material, it is formed using a material capable of realizing an appropriate reflectance, or surface treatment such as surface coating or mirror finishing is performed.

  The third reflector portion 241c is formed in front of the first and second reflector portions 241a and 241b, and includes a first upper wall 242a, a first left wall 242b, a first right wall 242c, and a first lower wall 242f. A second upper wall 242h that is inclined upward and forward from an upper position separated from the first upper wall 242a via a substantially B-shaped separation portion 242g connected to the front end edge of the first left wall via the separation portion 242g A second left wall 242i that inclines to the left from the left position separated from 242b, and a second right that inclines to the right from the right position that is separated from the first right wall 242c via the separation portion 242g.

In order to function, it is formed using a material capable of realizing an appropriate reflectance, or surface treatment such as surface coating or mirror finishing is performed.

  The optical member 250A disposed on the front surface side of the reflecting member configured as described above is a single-focus Fresnel lens. In the optical member 250A shown in FIG. 6D, central light passing back and forth through the center of a concentric circle. When the direct light and the reflected light from the first to fourth LEDs 231 to 234 are transmitted through the optical member 250A by placing the first to fourth LEDs 231 to 234 out of focus by having a focal point on the axis, The illuminance for illuminating the rear surface of the reel band 211 is substantially uniform, and the required illumination area can be illuminated without any spots.

  Here, the optical characteristics of the Fresnel lens will be described with reference to FIG. FIG. 7A shows a state in which a point light source is arranged at a focal point O on the central optical axis of the Fresnel lens, and the light diffused and emitted from the point light source becomes parallel to the central optical axis when passing through the Fresnel lens. Is refracted. As shown in FIG. 7B, when the point light source is brought close to the Fresnel lens on the central optical axis (positioned closer to the focal point O), the light transmitted through the Fresnel lens diffuses. When the point light source is moved away from the Fresnel lens on the central optical axis (at a position far from the focal point O), the light transmitted through the Fresnel lens converges toward one point on the central optical axis.

  As shown in FIG. 7C, when the point light source is shifted from the central optical axis in a plane separated from the Fresnel lens by the focal length, the light transmitted through the Fresnel lens is parallel to form an angle with the central optical axis. Become light. Then, as shown in FIG. 7D, in the state where the point light source is placed close to the Fresnel lens and shifted from the central optical axis, the light transmitted through the Fresnel lens is bent and diffused. The center of is at an angle with the central optical axis.

  Since the first to fourth LEDs 231 to 234 in the illumination device 220A described above are arranged at a position shorter than the focal point of the optical member 250A and shifted from the central optical axis, similarly to the arrangement of FIG. 7D. When the direct light from the first to fourth LEDs 231 to 234 is incident on the optical member 250 </ b> A, diffused light corresponding to the positional relationship between the focal point O and each point light source is irradiated to the inner surface of the reel band 211.

  That is, if the arrangement relationship between each point light source (first to fourth LEDs 231 to 234) and the focal point of the optical member 250A is appropriately set, the function as a light adjusting unit capable of irradiating the inner surface of the reel band 211 substantially evenly is optical. This can be realized only by the member 250A.

  However, the reel band is formed by the optical member 250A having a single-focus Fresnel lens configuration and the first to fourth LEDs 231 to 234 whose arrangement positions are limited to the front surface side of the illumination board 230A arranged substantially parallel to the optical member 250A. When it is going to irradiate the 211 inner surface, there may be a case where a part where spots are generated due to insufficient illuminance cannot be eliminated. Irradiation spots can be effectively eliminated by irradiating such low-illumination spots with the reflected light from the reflecting member.

  For example, as shown in FIG. 8A, a first pseudo parabolic surface P1 in which reflected light is aligned in a certain direction in the vicinity of a region separated from a point light source by a short distance X is assumed. The reflected light reflected by the first pseudo parabolic surface P1 is incident on the Fresnel lens obliquely, but the light transmitted through the Fresnel lens is refracted so as to be parallel to the central optical axis and irradiated to the inner surface of the reel band 211. Shall be. That is, it is only necessary to design the reflecting member so that the first indirect illumination light L1 is generated with respect to the low-illuminance illumination spots that are relatively close to the position where the point light source is disposed.

  On the other hand, as shown in FIG. 8B, a second pseudo parabolic surface P2 is assumed in which the reflected light is aligned in a certain direction in the vicinity of a region separated by a long distance Y from the point light source. The reflected light reflected by the second pseudo parabolic surface P2 is incident obliquely on the Fresnel lens, but the light transmitted through the Fresnel lens is refracted so as to be parallel to the central optical axis and irradiated to the inner surface of the reel band 211. Shall be. That is, it is only necessary to design the reflecting member so that the second indirect illumination light L2 is generated with respect to illumination spots with low illuminance generated at a position relatively distant from the position where the point light source is disposed.

  And when producing the 1st indirect illumination light L1 and the 2nd indirect illumination light L2, as shown in FIG.8 (c), as shown in FIG.8 (c), the 1st pseudo parabolic surface reflected in the area | region away from the point light source by the short distance X is shown. What is necessary is just to provide the 2nd pseudo parabolic surface P2 reflected in the area | region away from P1 and the point light source only by the long distance Y via the separation part S. The separation portion S need not be irradiated with at least light from a point light source, and therefore does not need to have a shape parallel to the Fresnel lens, and may be an inclined separation portion S ′. However, when the point light source is located slightly closer to the Fresnel lens, there may be a case where the separation portion S ′ becomes a reflection surface. It is desirable to have a parallel shape.

  Further, the first indirect illumination light L1 and the second indirect illumination light L2 do not necessarily have to be directed to enter the Fresnel lens, and the low illumination illumination generated on the inner surface of the reel band 211 even if some blurring occurs. Since it is only necessary to complement the spots so that the entire surface has a uniform illuminance, it is not necessary to form a highly accurate parabolic curved surface. As shown in FIG. 8D, the first simple reflection formed on a flat surface is used. The surface P1 ′ and the second simple reflection surface P2 ′ may be used. Further, when sufficient reflected light cannot be obtained due to a problem in processing of the reflecting member or excessive reflected light is generated, a reflection amount adjusting unit for adjusting the reflection amount may be provided. The reflection amount adjusting unit is configured to increase the reflection amount by applying a highly reflective paint, or by applying minute unevenness (so-called texture processing) to the reflection surface to diffuse and reflect light. The reflectance to the band 211 can be reduced, and a function of adjusting insufficient reflected light or excess reflected light can be formed on the reflecting member as a reflection amount adjusting unit, so that the degree of freedom in design is high.

  If the arrangement relationship between each point light source (first to fourth LEDs 231 to 234) and the reflecting member (first to third reflector portions 241a to 241c) and the irradiation position of the reflected light by the reflecting member are appropriately set, the reel The function as illuminance adjusting means that can adjust the illuminance according to the distance between the belt 211 and the light source can be realized only by the substrate case 240A.

  FIG. 9 illustrates the light irradiation on the inner surface of the reel band 211 by the lighting device 220A, divided into direct light and indirect light. Since the first to fourth LEDs 231 to 234 are arranged so as to be shorter than the focal length at positions shifted from the focus of the optical member 250A, as shown in FIGS. 9A1 and 9B1, the optical member 250A is used. The direct light that has passed through is diffused to illuminate the reel band 211 (the upper pattern illumination area 211a as the first section irradiation area, the middle pattern illumination area 211b as the second section irradiation area, and the third section irradiation area as the third section irradiation area). The lower pattern illumination region 211c is irradiated in the vertical direction). At this time. Illumination spots caused by direct light from the first to fourth LEDs 231 to 234 are, as shown in FIGS. 9B1 and 9B2, the first upper wall 242a, the upper partition wall 242d, the lower partition wall 242e, and the first Reflected light reflected by the lower wall 242f, the first left wall 242b, the first right wall 242c, the second left wall 242i, and the second right wall 242j passes through the optical member 250A and irradiates the inner surface of the reel band 211. It is solved with.

  A plurality of differently inclined reflecting surfaces provided in the reflecting member are inclined first reflecting portions (a first upper wall 242a, a first left wall 242b, a first right wall 242c, and The first lower wall 242f) and the second reflecting portion (the second upper wall 242h, the first left wall 242i, the first right wall 242j, the first lower wall 242k) can be separated from the light source 242g. However, if the areas where illumination spots occur are scattered at three or more locations, a third reflecting portion, a fourth reflecting portion,... good.

  As described above, in the reel unit 210 provided with the illumination device 220A, inexpensive standard luminance LEDs can be used as a plurality of point light sources without using expensive high luminance LEDs, and they are inexpensive and mass-productive. Since a good Fresnel lens can be used as the optical member 250A, it is possible to illuminate the reel band 211 effectively and without any spots at low cost.

  The optical member used as the illuminance adjusting means is not limited to the Fresnel lens, and a general optical lens (plano-convex lens, biconvex lens, meniscus convex lens, plano-concave lens, biconcave lens, meniscus concave lens) may be used. .

  When the Fresnel lens is the optical member 250A, the flat surface is opposed to the reel band 211, and the surface provided with the Fresnel structure (the light refraction function including concentric prisms) is attached to the substrate case 240A so as to face the light source. If so, there is an advantage that dust does not easily accumulate on the minute unevenness of the Fresnel structure, and that the cleaning device can be easily cleaned because the outer surface of the illumination device 220A is flat. Further, when a plate-like lens member is used as the illuminance adjusting means, the plate-like lens provided with a linear Fresnel shape is not limited to the one that diffuses light evenly in the circumferential direction of the optical axis like a normal Fresnel lens. If a member is used, light can be selectively diffused in a certain direction, and if a plate-like lens member provided on both sides so that the linear Fresnel shapes are orthogonal to each other, it is evenly distributed in the circumferential direction of the optical axis. Light can be diffused, and if these are used in combination, a more varied light refraction function can be realized.

  The LED used as the light source is not limited to monochromatic light, but can emit multicolor light (for example, three light emitting elements of RGB and four-color light emission of red light, green light, blue light, and mixed white light). You may use LED. If a multi-color light emitting LED is used, it can be regarded as a point light source at the same position regardless of the color of the light emitted, so the illumination spot is the same when the inner surface of the reel band 211 is irradiated only by direct light. Thus, it is possible to eliminate illumination spots by the illuminance adjustment means (the substrate case 240A having the reflector portion 241 alone, the optical member 250A alone, or the cooperation of the substrate case 240A and the optical member 250A).

<Control block>
Next, each control unit that functions as a control unit in the slot machine 100 including the lighting device 220A described above will be described in detail. FIG. 10 shows details of the main control unit 300, and FIG. 11 shows details of the sub-control unit 400.

<Configuration of main control unit>
First, the main control unit 300 of the slot machine 100 will be described with reference to FIG. The main control unit 300 includes a CPU 310 that is an arithmetic processing unit for controlling the entire main control unit 300, a data bus and an address bus for the CPU 310 to transmit and receive signals to and from each IC and each circuit, It has the structure described below.

  The clock correction circuit 314 is a circuit that divides the clock oscillated from the crystal oscillator 311 and supplies it to the CPU 310. For example, when the frequency of the crystal oscillator 311 is 12 MHz, the divided clock is 6 MHz. The CPU 310 operates by receiving the clock divided by the clock circuit 314 as a system clock.

  The CPU 310 is connected to a timer circuit 315 for setting a monitoring cycle for constantly monitoring the states of sensors and switches, which will be described later, and a transmission cycle of motor drive pulses, via a bus. When the power is turned on, the CPU 310 transmits the frequency dividing data stored in the predetermined area of the ROM 312 to the timer circuit 315 via the data bus.

  The timer circuit 315 determines an interrupt time based on the received frequency division data, and transmits an interrupt request to the CPU 310 at each interrupt time. In response to this interrupt request, the CPU 310 executes monitoring of each sensor and transmission of drive pulses. For example, when the system clock of the CPU 310 is set to 6 MHz, the frequency division value of the timer circuit 315 is set to 1/256, and the data for frequency division of the ROM 312 is set to 44, the reference time for this interrupt is 256 × 44 ÷ 6 MHz = 1. 877 ms.

  Connected to the CPU 310 are a ROM 312 for storing programs for controlling each IC, lottery data used for internal winning lottery, reel stop positions, and a RAM 313 for storing temporary data.

The stop button sensor 322 is installed in each of the stop buttons 136a to 136c, and detects the operation of the stop button by the player.

  The MAX bet button sensor 323 detects that the MAX bet button 131 has been operated, the ONE bet button sensor 322 detects that the ONE bet button 132 has been operated, and each detection output is stored electronically in the RAM 313. This is used to identify the number of medals that have been used as gaming medals. For example, when the ONE bet button sensor 324 corresponding to the ONE bet button 132 becomes H level, the CPU 310 electronically inserts one stored medal and the MAX bet button sensor 323 corresponding to the MAX bet button 131 When the H level is reached, three stored medals are electronically inserted. When the MAX bet button 131 is pressed, two coins are inserted when the number of stored medals is two, and one coin is inserted when the number is one.

  The settlement button switch 325 detects that the settlement button 138 has been operated, and the CPU 310 that receives this operation drives the hopper motor to pay out the stored medals from the medal payout device (hopper). The reset switch 326 clears a specific area of the RAM 313 and returns to a normal operation state when operated after recovery from an error or the like. The medal payout sensor 327 is for detecting a medal paid out by the medal payout device and performing an appropriate number of payout controls. Each of the above sensors may be a non-contact type sensor or a contact type sensor.

  Further, an input interface 361 and output interfaces 370 and 371 are connected to the CPU 310 via the address decoding circuit 350 to the address bus. The CPU 310 exchanges signals with external devices via these interfaces.

Specifically, the index sensor 328 is installed at a predetermined position of the mounting base of each of the reels 110 to 112, and becomes H level each time the light shielding piece provided on the reel passes through the index sensor 328. When detecting this signal, the CPU 310 determines that the reel has made one rotation, and resets the rotational position information of the reel to zero.

  The output interface 370 drives a reel motor driving unit 330 for driving a reel and a hopper motor of a medal payout device (a device for paying out a medal accumulated in a bucket from a medal payout outlet 165, not shown).

  A random number generation circuit 317 is connected to the CPU 310 via a data bus. The random number generation circuit 317 is an increment counter capable of incrementing a value within a certain range based on the clocks oscillated from the crystal oscillator 311 and the crystal oscillator 316 and outputting the count value to the CPU 310. It is used for various lottery processes including the internal lottery. The random number generation circuit 317 includes, for example, two random number counters (a counter that increments a value from 0 to 65535 using the clock frequency of the crystal oscillator 311 and a value from 0 to 16777215 using the clock frequency of the crystal oscillator 316. Counter).

  Further, an output interface 371 for transmitting a command to the sub-control unit 400 is connected to the data bus of the CPU 310.

<Configuration of sub-control unit>

The sub-control unit 400 includes a CPU 410 that is an arithmetic processing unit that controls the entire sub-control unit 400 based on a main control command and the like transmitted from the main control unit 300, and the CPU 410 transmits and receives signals to and from each IC and each circuit. It has a data bus and an address bus for performing, and has a configuration described below.

  The clock correction circuit 414 is a circuit that corrects the clock oscillated from the crystal oscillator 411 and supplies the corrected clock to the CPU 410 as a system clock.

  Further, a timer circuit 415 is connected to the CPU 410 via a bus. The CPU 410 transmits the frequency dividing data stored in the predetermined area of the ROM 412 to the timer circuit 415 via the data bus at a predetermined timing. The timer circuit 415 determines an interrupt time based on the received frequency division data, and transmits an interrupt request to the CPU 410 at each interrupt time. The CPU 410 controls each IC and each circuit based on the interrupt request timing.

  In addition, the CPU 410 temporarily stores a ROM 412 in which commands and data for controlling the entire sub-control unit 400, backlight lighting patterns and data for controlling various displays, and the like are stored. The RAM 413 is connected via each bus.

  The CPU 410 is connected to an input / output interface 460 for transmitting and receiving external signals. The input / output interface 460 is connected to an illumination device 220 and a RAM 413 for illuminating the designs of the reels 110 to 112 from the back. A reset switch 421 for clearing the data is connected.

  An input interface 461 for receiving a main control command from the main control unit 300 is connected to the CPU 410 via a data bus, and an effect process that excites the entire game based on the command received via the input interface 461. Etc. are executed.

  A sound source IC 480 is connected to the data bus and address bus of the CPU 410. The sound source IC 480 controls sound according to a command from the CPU 410. The sound source IC 480 is connected to a ROM 481 that stores sound data. The sound source IC 480 amplifies the sound data acquired from the ROM 481 by the amplifier 482 and outputs the sound data from the speaker 483.

  Similarly to the main controller 300, the CPU 410 is connected to an address decoding circuit 450 for selecting an external IC, and the address decoding circuit 450 has an output interface for outputting signals to various effect lamps. 470, an input interface 461 for receiving a command from the main control unit 300, an input interface 471 for inputting a signal from the liquid crystal screen control unit 500, a clock IC 424, and a signal to the 7-segment display 440 are output.

Conversely, the CPU 410 receives a signal from the liquid crystal screen control unit 500 via the input interface 471. That is, the CPU 410 performs bidirectional communication with the liquid crystal screen control unit 500 via the demultiplexer 419 and the input interface 471. The liquid crystal screen control unit 500 is a device that performs display control on the LCD 180.

<Second configuration example of lighting device>
FIG. 12 is a perspective view showing a schematic structure of the illumination device 220B according to the second configuration example, and FIG. 13 is an exploded perspective view of the illumination device 220B according to the second configuration example. The illuminating device 220B includes a reflector substrate 243 that includes a first LED 231 for upper pattern illumination, a second LED 232 for middle pattern illumination, a second LED 233 for lower pattern illumination, and a fourth LED 234 for lower pattern illumination as a plurality of light sources. The substrate case 240B is housed from the back side, and the front opening of the substrate case 240B is closed with an optical member 250B.

  In this way, a plurality of compartment illumination areas (for example, the upper picture drawn in the first compartment illumination area, the middle picture depicted in the second compartment illumination area, and the third compartment illumination area constituting the illumination area in the reel band) A light source is individually provided corresponding to each of the lower pictures drawn, and the first LED 231 and the fourth LED 234 are provided corresponding to each of the upper picture and the lower picture whose reel band 211 and the light source are close to each other as one light source. If the configuration in which the second and third LEDs 232 and 233 are provided as the two light sources corresponding to the central pattern having a long distance between the reel band 211 and the light source, the central pattern has an illuminance compared with the illuminance of the upper and lower patterns. It is possible to prevent the shortage and to illuminate the illumination area, which is the total of the three partitioned illumination areas, with a substantially uniform illuminance. That is, according to the distance between each section irradiation area of the reel band 211 and the light source, the illuminance adjusting means is formed by changing the number of light sources, and the illuminance of each section irradiation area is made uniform, and the inner surface of the reel band 211 is Irradiate substantially uniformly.

  In addition, when a product having the same luminous intensity is used for the first to fourth LEDs 231 to 234 that are light sources, the middle pattern may become brighter than the upper and lower patterns, and the middle part obtained by using two light sources A measure to select an LED with a luminous intensity so that the illuminance of the pattern is the same as the illuminance of the upper and lower patterns is also conceivable. However, since two types of LEDs must be incorporated, the productivity of the apparatus deteriorates and the cost increases. It leads to up. Therefore, in the illumination device 220B of the present configuration example, even if two light sources having the same luminous intensity as each of the light sources for the upper and lower picture patterns are used for the middle picture, the illuminance adjustment is performed so that the illuminance of the upper and lower picture patterns is not imbalanced. As a means, the reflecting structure of the reflector portion 243B and the light refraction function of the optical member 250B were adopted. Hereinafter, these will be described.

  The reflector part 243 of the substrate case 240B includes a first light guide part 2431 for upper picture illumination, a second light guide part 2432 for middle picture illumination, and a third light guide part 2433 for lower picture illumination provided in the vertical direction. The first LED 231 on the illumination board 230B faces the first light guide part 2431, the second LED 232 and the third LED 233 face the second light guide part 2432 on the illumination board 230B, and the third light guide part 2433 faces. Faces the fourth LED 234 on the illumination substrate 230B, and the light emitted from the first to fourth LEDs 231 to 234 is reflected by the direct incident light directly incident from the back side of the optical member 250B and the reflector 243 of the substrate case 240. Indirect incident light incident on the back side of the optical member 250B is generated, and these direct incident light and indirect incident light are generated by the optical member 2. When passing through the 0B, and thus irradiated on the back surface side of the reel strip 211 from the front side of the optical member 250B depending on the optical properties.

  That is, in the illumination device 220B of this configuration example, the illumination light from the first to fourth LEDs 231 to 234 provided on the illumination substrate 230B is applied to the illumination area of the reel band 211 (three part patterns facing forward from the reel display window 113). The function as illuminance adjusting means for adjusting the illuminance to illuminate the inner surface of the reel band 211 by changing the angle of light so as to be directed to the corresponding region) is realized by the reflector portion 243 of the substrate case 240B and the optical member 250B. It is.

  Unlike the illumination device 220A of the first configuration example described above, in the illumination device 220B of the second configuration example, the first lens unit 251, the second lens unit 252, and the second lens unit 250B divided into three in the vertical direction as the optical member 250B. A trifocal Fresnel lens having a focal point is used for each of the three lens units 253, and the upper pattern illumination area, which is the first section illumination area in the reel band 211, is irradiated with light from the first lens section 251 and the second section illumination area. A configuration in which a certain middle pattern illumination region is individually illuminated with irradiation light from the second lens unit 252 and a lower pattern illumination region which is a third section illumination region with illumination light from the third lens unit 253 is employed. Hereinafter, the substrate case 240B and the optical member 250B will be described in detail.

  14A is a front view of the illumination device 230B, FIG. 14B is a front view of the substrate case 240B housing the illumination substrate 230B, and FIG. 14C is a cross-sectional view taken along line CC in FIG. 6D is a cross-sectional view taken along the line DD in FIG. 14A.

  The reflector portion 243 in the substrate case 240B has a reflection surface that receives light that is not directly irradiated onto the irradiation area of the reel band 211 from the first to fourth LEDs 231 to 234 that are light sources and reflects the light toward the irradiation area of the reel band 211. It consists of members.

  The first reflector portion 2431 receives the irradiation light from the first LED 231 and directs the reflected light toward the first lens portion 251 of the optical member 250B, and forwards so as to surround the irradiation direction of the first LED 231 that is a point light source.

An inclined left wall 2434b that extends downward and extends forward, and extends to the front, and a right end portion of the upper wall 2434a and a right end portion of the second separation portion 2431d. The inclined right wall 2434c that protrudes and expands forward is formed by the upper surface of the first partition wall 2435a that protrudes forward from the lower edge of the second separation portion 2431d. The first reflection unit 2431a, the second reflection unit 2431c, the upper wall 2434a, the left wall 2434b, the right wall 2434c, and the first partition wall 2435a are reflections including an inclined reflection unit that the light from the first LED 231 can reach. In order to function as a surface, it is formed using a material capable of realizing an appropriate reflectance, or surface treatment such as surface coating or mirror finishing is performed.

  The second reflector unit 2432 receives the irradiation light from the second and third LEDs 232 and 233 and directs the reflected light to the second lens unit 252 of the optical member 250B. In the pattern illumination area, the distance from the point light source provided on the illumination board 230B is greater than the distance from the above-described upper pattern illumination area irradiated by the first lens unit 251 and the lower pattern illumination area irradiated by the third lens unit 253 described later. Therefore, as described above, the amount of light emitted from the second lens unit 252 to the inner surface of the reel band 212 is increased by providing two point light sources close to each other.

  Specifically, a semi-bowl-shaped first left reflecting portion 2432a1 that expands forward so as to surround the irradiation direction of the second LED 232 that is a point light source, and a front expansion so as to surround the irradiation direction of the third LED 233.

The first separation part 2432b, the semi-mortar-shaped second left reflection part 2432c1 that expands forward from the left outer half of the first separation part 2432b, and the front extension from the outer right half of the first separation part 2432b The second right reflecting portion 2432c1 having a semi-rotating bowl shape and the substantially right-shaped front end edges of the second left and right reflecting portions 2432c1 and 2432c2 are bent in a direction substantially parallel to the optical member 250A and spread in a substantially rectangular shape. 2 separation part 2432d, the lower surface of the first partition wall 2435a connected to the upper edge of the second separation part 2432d, and the upper surface of the second partition wall 2435b projecting forward from the lower edge of the second separation part 2432d. . The first left reflecting portion 2432a, the first right reflecting portion 2432a2, the second left reflecting portion 2432c1, the second right reflecting portion 2432c2, the first partition wall 2435a, and the second partition wall 2435b are supplied from the second LED 232 or the third LED 233. In order to function as a reflecting surface including an inclined reflecting portion to which light can reach, it is formed using a material capable of realizing an appropriate reflectance, or surface treatment such as surface coating or mirror finishing is performed.

  When only one high-brightness LED capable of correcting the illuminance reduction from the illumination board 230B to the middle pattern illumination area is used, a reflective surface structure similar to the first reflector 2431 described above may be employed.

  The third reflector portion 2433 receives the irradiation light from the fourth LED 234 and directs the reflected light to the third lens portion 253 of the optical member 250B, and has a shape obtained by inverting the first reflector portion 2431 described above in the vertical direction. It is. Specifically, a bowl-shaped first reflecting portion 2433a that expands forward so as to surround the irradiation direction of the fourth LED 234 that is a point light source, and the optical member 250A substantially from the front edge of the first reflecting portion 2433a. An annular first separation portion 2433b that bends in a parallel direction, a bowl-shaped second reflection portion 2433c that expands forward from the outer periphery of the first separation portion 2433b, and a front end of the second reflection portion 2433c A second separation portion 2433d that is bent in a direction substantially parallel to the optical member 250A from the edge and spreads in a substantially square shape; a second partition wall 2435b that continues to the upper edge of the second separation portion 2433d; and a second separation portion 2433d An inclined left wall 2434b that extends to the front and extends to the front side, an inclined right wall 2434c that extends to the front side to the right side of the second separation part 2433d, and a second separation part 2433d Lower edge Preliminary lateral walls 2434B, constituted by the lower wall 2434d that inclined downward toward the front continuous to the lower edge of 2434C. The first reflecting portion 2433a, the second reflecting portion 2433c, the second partition wall 2435b, the left wall 2434b, the right wall 2434c, and the lower wall 2434d are reflections including an inclined reflecting portion that the light from the fourth LED 234 can reach. In order to function as a surface, it is formed using a material capable of realizing an appropriate reflectance, or surface treatment such as surface coating or mirror finishing is performed.

  In the illumination device 220B configured as described above, as shown in FIG. 15, the first reflector portion 2431 in the substrate case 240B and the first lens portion 251 in the optical member 250B cooperate to form the reel band 211. It functions as a light adjusting means for illuminating the upper pattern illumination area 211a without any spots, and the second reflector portion 2432 in the substrate case 240B and the second lens portion 252 in the optical member 250B cooperate with each other. It functions as a light adjusting means for illuminating the middle pattern illumination region 211b without any spots, and the third reflector portion 2433 in the substrate case 240B and the third lens portion 253 in the optical member 250B cooperate with each other. It functions as a light adjustment means for illuminating the central pattern illumination area 211c without any spots. .

  Although the optical characteristics of the first lens portion 251 and the third lens portion 253 in the optical member 250B are substantially the same, the optical characteristics of the second lens portion 251 are different. As shown in FIG. 16 (a), the second lens unit 252 as shown in FIG. 16 (b) rather than the distance to the focal point O1 of the first lens unit 251 (or the third lens unit 253). Since the distance to the focal point O2 is set to be long, when the separation distance between the optical member 250B and the illumination substrate 230B is arranged closer than the focal length of the first and third lens portions 251 and 253, the first The second and third LEDs 232 and 233 are more diffuse than the light incident on the first and third lens portions 251 and 253 as diffused light from the fourth LEDs 231 and 234 and transmitted through the first and third lens portions 251 and 253. The degree to which the light incident on the second lens unit 252 as diffused light is transmitted through the second lens unit 252 and spreads becomes larger.

  In addition to this, as shown in FIG. 17 (a1), illumination spots generated when the inner surface of the reel band 211 is irradiated by direct light directly applied to the first lens unit 251 from the first LED 231 are shown in FIG. 17 (a2). ), The reflected light reflected from the first LED 231 to the reflecting surface of the first reflector 2431 passes through the first lens unit 251 and is applied to the inner surface of the reel band 211, so that the illumination is substantially uniform. Can be realized. Also, as shown in FIG. 17 (b1), the illumination spots generated when the inner surface of the reel band 211 is irradiated with the direct light directly irradiated on the second lens portion 252 from the second and third LEDs 232 and 233 are shown in FIG. As shown in (b2), the reflected light reflected from the second and third LEDs 232 and 233 to the reflecting surface of the second reflector portion 2432 passes through the second lens portion 252 and is applied to the inner surface of the reel band 211. Complementary and substantially uniform illumination can be achieved. The illumination spots generated when the inner surface of the reel band 211 is irradiated by the direct light directly irradiated on the third lens unit 253 from the fourth LED 234 are reflected light reflected from the fourth LED 234 on the reflection surface of the third reflector unit 2433. It is complemented by being transmitted through the third lens portion 253 and irradiating the inner surface of the reel band 211, and substantially uniform illumination can be realized.

<Third configuration example of lighting device>
Next, the illuminating device 220C of a 3rd structural example is shown. 18A is a perspective view of a state in which the illumination board 230C is housed in the board case 240C and the front optical member 250C is removed, and FIG. 18B is a front view of the optical member 250C. .

  The illumination device 220C according to this configuration example has a configuration similar to the illumination device 220B according to the second configuration example described above, and the illumination light from the first LED 231 is irradiated by an illuminance adjustment unit including the first reflector unit 2441 and the first lens unit 251. The upper pattern illumination area is irradiated with no spots, and the illumination light from the fourth LED 234 is irradiated to the lower pattern illumination area without any spots by the illuminance adjusting means comprising the third reflector unit 2443 and the third lens unit 253. Regarding the illumination area, the second left lens portion 252a and the second right lens portion 252b having individual focal points respectively direct light from the second LED 232, reflected light from the second reflector portion 2442, direct light from the third LED 233, and the first light. 2 Illuminate without spots by transmitting the light reflected by the reflector 2442 Than is. Thus, if the focal position is divided finely, it is possible to finely eliminate illumination spots.

<The 4th structural example of an illuminating device>
FIG. 19 shows an illumination device 220D of the fourth configuration example. 19A is an external perspective view of the illumination device 220D, FIG. 19B is a front view of the illumination device 220D, and FIG. 19C is an illumination device disposed inside the reel band 211. It is explanatory drawing of the state which illuminates the upper pattern illumination area | region 211a, the middle pattern illumination area | region 211b, and the lower pattern illumination area | region 211c by 220D.

  In the illumination device 220D of this configuration example, the substrate case 240D is disposed on the front side of the illumination substrate 230D, so that the irradiation light from the upper LED 235a is guided to the upper pattern illumination region 211a, and the upper light guide chamber 2451 and the middle LED 235b. A middle light guide chamber 2452 that guides irradiation light to the middle pattern illumination region 211b and a lower light guide chamber 2453 that guides irradiation light from the lower LED 235c to the lower pattern illumination region 211c are formed, and each of the pattern illumination regions 211a to 211c is formed. The illuminance is a configuration that depends on the luminous intensity of the corresponding light source.

  Therefore, in the illumination device 220D of this configuration example, the distance between the upper pattern illumination area 211a and the upper LED 235a is substantially equal to the distance between the lower pattern illumination area 211c and the lower LED 235c, but the middle pattern illumination area 211b and the middle LED 235b Since the distance between the upper and lower LEDs 235a and 235c is appropriately higher than that of the upper LEDs 235a and 235c, the middle LED 235b is used as an illuminance adjusting means to compensate for a decrease in illuminance in the central pattern illumination area 211b. The illumination area of the band 211 is irradiated substantially uniformly.

  In the illumination device 220D in this configuration example, since the illuminance that illuminates each of the pattern illumination areas 211a to 211c depends on the luminous intensity of each of the LEDs 235a to 235c, a special reflecting structure or the like is provided on the inner surface of each of the light guide chambers 2451 to 2453. Although it is not necessary to provide, the process which raises a light reflectance may be given, and conversely, the reflection reduction process by a grain structure may be given. Moreover, you may make it adjust the illuminance with respect to each pattern illumination area | region 211a-211c by providing an optical member, changing the convergence / diffusion of irradiation light, or the irradiation direction.

<The 5th structural example of an illuminating device>
FIG. 20 shows a lighting device 220E of the fifth configuration example. 20A is a front view of the illumination device 220E, FIG. 20B is a cross-sectional view taken along line BB in FIG. 20A, and FIG. 20C is FIG. 20A. It is arrow sectional drawing of a CC line.

  In the illumination device 220E of this configuration example, the substrate case 240E is disposed on the front surface side of the illumination substrate 230E, whereby the irradiation light from the upper LED 236a is guided to the upper pattern illumination area 211a and the upper light guide chamber 2461 and the middle LED 236b. The lower light guides the irradiation light from the central reflection light guide chamber 2462 and the lower LED 236c, which guides the irradiation light to the middle pattern illumination area 211b and also reflects the reflected light hitting the four side walls to the middle pattern illumination area 211b, to the lower pattern illumination area 211c. A light chamber 2463 is formed, and LEDs having the same luminous intensity are used as the LEDs 236a to 236c that illuminate the pattern illumination areas 211a to 211c.

  Therefore, in the illumination device 220E of the present configuration example, the illuminance adjustment means is formed by forming the reflection amount adjustment unit 260 made of a thin film or a thin plate of metallic paint that increases the reflectance on at least four side walls of the middle reflection light guide chamber 2462. The light emitted from the middle LED 236b hits the reflection amount adjusting unit 260 formed on the side wall of the middle reflection light guide chamber 2462 in addition to the direct light emitted to the back surface of the reel band 211, and has a high reflectance. Reflected light toward the back of the band 211 is added.

  Accordingly, even if the distance between the middle pattern illumination region 211b and the middle LED 236b is longer than the distance between the upper and lower pattern illumination regions 211a and 211c and the upper and lower LEDs 236a and 236c, the irradiation light from the middle LED 236b is directly light. Since the reflected light is efficiently guided to the middle pattern illumination area 211b, the illuminance is increased, and the illuminance of the upper and lower pattern illumination areas 211a and 211c by the upper and lower LEDs 236a and 236c and the illuminance of the middle pattern illumination area 211b by the middle LED 236b are increased. Adjustments can be made equally, and the illumination area of the reel band 211 can be illuminated substantially uniformly.

  The reflection amount adjusting unit 260 functioning as the illuminance adjusting means may be provided on the four side walls of the middle reflection light guide chamber 2462 as a range mainly irradiated with the light emitted from the middle LED 236b. In the process of repeating reflection, a light beam that hits the front surface of the illumination board 230 is generated in a small amount. Therefore, in the present configuration example, the reflection amount adjustment unit 260 is also formed on the front surface of the illumination board 230, and the illuminance of the central pattern illumination area 211b. Can be increased more effectively. Moreover, you may make it adjust the illuminance with respect to each pattern illumination area | region 211a-211c by providing an optical member, changing the convergence / diffusion of irradiation light, or the irradiation direction.

<The 6th structural example of an illuminating device>
FIG. 21 shows a lighting device 220F of the sixth configuration example. 21A is a front view of the illumination device 220F, FIG. 21B is a cross-sectional view taken along the line BB in FIG. 21A, and FIG. 21C is the view in FIG. It is arrow sectional drawing of a CC line.

  The illumination device 220F of the present configuration example arranges the substrate case 240F on the front side of the illumination substrate 230F, thereby guiding the irradiation light from the upper LED 236a to the upper pattern illumination region 211a and irregularly reflecting the light hitting the four side walls. The diffused light from the upper diffused light guide chamber 2471 and the middle LED 236b is guided to the middle pattern illumination area 211b, and the emitted light from the lower LED 236c is guided to the lower pattern illumination area 211c and hits the four side walls. The lower diffusion light guide chamber 2473 for diffusing the reflected light by irregular reflection is formed. Each LED 236a to 236c that illuminates each of the pattern illumination areas 211a to 211c uses an LED having the same luminous intensity as the illumination device 220E of the fifth configuration example described above.

  Therefore, in the illumination device 220F of this configuration example, minute unevenness (for example, embossing) that reduces the reflectance is generated on at least four side walls of the upper diffusion light guide chamber 2471 and the lower diffusion light guide chamber 2473. By forming the reflection amount adjusting unit 270, it is an illuminance adjusting means, and the light that is irradiated from the upper and lower LEDs 236a and 236c and hits the four side walls is diffusely reflected by the reflection amount adjusting unit 270, so The light diffuses and attenuates in the chambers 2471 and 2473 to reduce the amount of light applied to the back surface of the reel band 211.

  On the other hand, even if the distance between the middle pattern illumination region 211b and the middle LED 236b is longer than the distance between the upper and lower pattern illumination regions 211a and 211c and the upper and lower LEDs 236a and 236c, the irradiation light from the middle LED 236b is transmitted to the middle light guide chamber. The reflected light that has been reflected by the four side walls 2472 is irradiated to the back surface of the reel band 211 with a light amount corresponding to the reflection condition, so that the direct light and the reflected light are guided to the middle picture illumination area 211b. Therefore, the illuminance of the upper and lower pattern illumination areas 211a and 211c by the upper and lower LEDs 236a and 236c and the illuminance of the middle pattern illumination area 211b by the middle LED 236b can be adjusted equally, and the illumination area of the reel band 211 is made substantially uniform. It can be irradiated.

  In addition, it is necessary and sufficient if the reflection amount adjusting unit 270 functioning as the illuminance adjusting means is provided on the four side walls of the upper and lower diffusion light guide chambers 2471 and 2473 as a range mainly irradiated with the irradiation light from the upper and lower LEDs 236a and 236c. However, the irregularly reflected light beam may be reflected so that it strikes the front surface of the illumination board 230 and faces the rear surface of the reel band 211. Therefore, in this configuration example, the reflection amount adjustment unit 270 is also formed on the front surface of the illumination board 230. The illuminance of the upper and lower pattern illumination areas 211a and 211c is effectively reduced so that the illuminance can be reduced to the same level as that of the middle pattern illumination area 211b by the middle LED 236b. Moreover, you may make it adjust the illuminance with respect to each pattern illumination area | region 211a-211c by providing an optical member, changing the convergence / diffusion of irradiation light, or the irradiation direction.

<7th structural example of an illuminating device>
FIG. 22 shows a lighting device 220G of the seventh configuration example. FIG. 22A is an external perspective view of the illumination device 220G including the illumination substrate 230G, the substrate case 240G, and the optical member 250G, and FIG. 22B is a perspective view in a state where the optical member 250G is removed.

  The illumination device 220G of the present configuration example has a substrate case 240G disposed on the front side of the illumination substrate 230G, thereby leading the irradiation light from the upper LED 236a to the upper pattern illumination area 211a from the upper light guide chamber 2451 and the middle LED 236b. The middle light guide chamber 2452 that guides the irradiation light to the middle pattern illumination region 211b and the lower light guide chamber 2453 that guides the irradiation light from the lower LED 236c to the lower pattern illumination region 211c are formed, and the front side of all the light guide chambers 2451 to 2453 is formed. It is closed by the optical member 250G. The LEDs 236a to 236c that illuminate the pattern illumination areas 211a to 211c use LEDs having the same light intensity as the illumination devices 220E and 220F of the fifth and sixth configuration examples described above.

  Here, the optical member 250G has the above-described trifocal Fresnel lens configuration, and the first lens portion 251, the second lens portion 252 and the third lens portion 253 are respectively composed of an upper light guide chamber 2451, a middle light guide chamber 2452, An arrangement corresponding to each of the front surfaces of the lower light guide chamber 2453 is provided on one surface of the first lens portion 251 and the third lens portion 253 (surface not forming the Fresnel structure), and minute unevenness that reduces the reflectance. By forming a reflection amount adjusting unit 270 that generates (for example, embossing), it forms an illuminance adjusting means, and is irradiated from the upper and lower LEDs 236a and 236c, and the first and third lens portions 251 and 253 of the optical member 250G. The diffused light is diffused by being irregularly reflected by the reflection amount adjusting unit 270, and the amount of light applied to the back surface of the reel band 211 is reduced.

  On the other hand, even if the distance between the middle pattern illumination area 211b and the middle LED 236b is longer than the distance between the upper and lower pattern illumination areas 211a and 211c and the upper and lower LEDs 236a and 236c, the second pattern illumination area 211b corresponds to the front surface of the middle light guide chamber 2452. Since the reflection amount adjusting unit 270 is not formed in the two lens unit 252, the light irradiated from the middle LED 252 is transmitted through the second lens unit 252 without being attenuated and irradiated to the back surface of the reel band 211 with an appropriate amount of light. Is done. Therefore, the illuminance of the upper and lower pattern illumination areas 211a and 211c by the upper and lower LEDs 236a and 236c and the illuminance of the middle pattern illumination area 211b by the middle LED 236b can be adjusted equally, and the illumination area of the reel band 211 is made substantially uniform. It can be irradiated.

  The reflection amount adjusting unit 270 functioning as the illuminance adjusting unit is not only provided in the first and third lens units 251 and 253 of the optical member 250G, but also as in the illumination device 220F of the sixth configuration example described above. The illuminance may be more effectively reduced by forming the four light guide chambers 2451 and 2453 on the four side walls and the front surface of the illumination board 230G.

<Eighth configuration example of lighting device>
FIG. 23 shows an illumination device 220H of the eighth configuration example. FIG. 23A is an external perspective view of the illumination device 220H including the illumination substrate 230H, the substrate case 240H, and the optical member 250H, and FIG. 23B is a perspective view in a state where the optical member 250H is removed.

  In the illumination device 220H of this configuration example, the substrate case 240H is disposed on the front side of the illumination substrate 230H, whereby the upper light guide chamber 2451 that guides the irradiation light from the first LED 231 to the upper pattern illumination region 211a is disposed in the vicinity. A central light guide chamber 2452 that guides the irradiation light from the 2LED 232 and the second LED 233 to the central pattern illumination region 211b, and a lower light guide chamber 2453 that guides the irradiation light from the fourth LED 234 to the lower pattern illumination region 211c are formed. The front side of ˜2453 is closed by the optical member 250H. The first to fourth LEDs 231 to 234 that illuminate the pattern illumination areas 211a to 211c use LEDs having the same light intensity as the illumination devices 220A to 220D of the first to fourth configuration examples described above.

  Here, the optical member 250H has the above-described trifocal Fresnel lens configuration, and the first lens portion 251, the second lens portion 252 and the third lens portion 253 are respectively composed of an upper light guide chamber 2451, a middle light guide chamber 2452, An arrangement corresponding to each of the front surfaces of the lower light guide chamber 2453, and one surface of the second lens portion 252 (the surface where the Fresnel structure is not formed) has minute unevenness (for example, embossing) that reduces the reflectance. By forming the reflection amount adjusting unit 270 that generates the light, the light intensity adjusting means is formed, and the light that is irradiated from the second and third LEDs 232 and 233 and reaches the second lens unit 252 of the optical member 250H is adjusted in reflection amount. The diffused light is diffused by the part 270 to reduce the amount of light applied to the rear surface of the reel band 211.

  That is, considering that the distance between the middle pattern illumination area 211b and the second and third LEDs 232 and 233 is longer than the distance between the upper and lower pattern illumination areas 211a and 211c and the first and fourth LEDs 231 and 234, 2 By increasing the amount of light by using two light sources, even if the illuminance of the middle pattern illumination area 211b is too high compared to the illuminance of the upper and lower pattern illumination areas 211a and 211c, the second light source corresponding to the front surface of the middle light guide chamber 2452 can be obtained. Since the reflection amount adjusting unit 270 is formed in the second lens unit 252, the light emitted from the second and third LEDs 232 and 233 is appropriately attenuated and transmitted through the second lens unit 252, and the reel band with a suppressed light amount. The rear surface of 211 is irradiated. Therefore, the illuminance of the upper and lower pattern illumination areas 211a and 211c by the first and fourth LEDs 231 and 234 and the illuminance of the middle pattern illumination area 211b by the second and third LEDs 232 and 233 can be adjusted equally, and the reel band 211 The illumination area can be irradiated substantially uniformly.

  The reflection amount adjusting unit 270 functioning as the illuminance adjusting unit is not only provided in the second lens unit 252 of the optical member 250H, but also in the middle light guide chamber 2452 like the illumination device 220F of the sixth configuration example described above. The illuminance may be further effectively reduced by forming the four side walls and the front surface of the illumination board 230H.

<Ninth configuration example of lighting device>
FIG. 24 shows a lighting device 220I of the ninth configuration example. FIG. 24A is an external perspective view of the illumination device 220I including the illumination substrate 230I, the substrate case 240I, and the optical member 250I. FIG. 24B is a front view of the optical member 250I, and FIG. ) Is an explanatory diagram of a state in which the upper pattern illumination area 211a, the middle pattern illumination area 211b, and the lower pattern illumination area 211c are illuminated by the illumination device 220I disposed inside the reel band 211.

  The illuminating device 220I of the present configuration example is provided with a substrate case 240I on the front side of the illumination substrate 230I, so that the irradiation light from the upper LED 236a is guided to the upper pattern illumination region 211a and from the upper light guide chamber 2451 and the middle LED 236b. The middle light guide chamber 2452 that guides the irradiation light to the middle pattern illumination region 211b and the lower light guide chamber 2453 that guides the irradiation light from the lower LED 236c to the lower pattern illumination region 211c are formed, and the front side of all the light guide chambers 2451 to 2453 is formed. It is closed by the optical member 250I. The LEDs 236a to 236c that illuminate the pattern illumination areas 211a to 211c use LEDs having the same luminous intensity as in the illumination devices 220E to 220G of the fifth to seventh configuration examples described above.

  Here, the optical member 250I has the above-described single-focus Fresnel lens configuration, and the central LED 236b is disposed at a position shorter than the focal length on the central optical axis, thereby being irradiated from the central LED 236b and transmitted through the optical member 250I. Adjustment is made so that the light is evenly diffused in the entire circumferential direction and the entire area of the middle pattern illumination area 211b is illuminated. On the other hand, the light emitted from the upper LED 236a disposed appropriately above the middle LED 236b on the front side of the illumination board 230I parallel to the optical member 250I passes through the optical member 250I and diffuses, but the diffusion direction is the center. Since it is biased toward the optical axis side (downward), the light emitted from the upper LED 236a reaches not only the entire upper picture illumination area 211a but also the upper part of the middle picture illumination area 211b. Similarly, the light emitted from the lower LED 236c disposed appropriately below the middle LED 236b on the front side of the illumination board 230I parallel to the optical member 250I passes through the optical member 250I and diffuses, but the diffusion direction is Since it is biased toward the center optical axis side (upward), the light emitted from the lower LED 236c extends to the lower part of the middle picture illumination area 211b in addition to the entire lower picture illumination area 211c.

  That is, in the present configuration example, the optical member 250I is an illuminance adjusting unit, and the distance between the middle pattern illumination area 211b and the middle LED 236b is larger than the distance between the upper and lower pattern illumination areas 211a and 211c and the upper and lower LEDs 236a and 236c. However, the illumination intensity of the middle pattern illumination area 211b is lower than the illumination intensity of the upper and lower pattern illumination areas 211a and 211c, but a part of the light emitted from the upper LED 236a and the lower LED 236c is irradiated to the middle pattern illumination area 211b. The illumination intensity of the reel band 211 is made substantially uniform by equally adjusting the illuminance of the upper and lower pattern illumination areas 211a and 211c by the upper and lower LEDs 236a and 236c and the illuminance of the middle pattern illumination area 211b by the middle LED 236b. I was able to irradiate. In addition, the adjustment of the irradiation area by each of the LEDs 236a to 236c can be realized by the optical member 250I configured by a single-focus Fresnel lens, and there is an advantage that the productivity is low and the productivity is high.

  Further, as the illuminance adjusting means, a reflection amount adjusting unit 260 for increasing the amount of light transmitted through the optical member 250I from the middle LED 236b is formed on the four side walls of the middle light guide chamber 2452 and the front surface of the illumination board 230I, or the upper and lower LEDs 236a, 236c. The reflection amount adjusting unit 270 that suppresses the amount of light transmitted through the optical member 250I may be formed on the four side walls of the upper and lower light guide chambers 2451 and 2453 and the front surface of the illumination board 230I, or on one surface of the optical member 250I.

If so, it can be applied to any game machine. A pachinko machine 600 as a game table shown in FIG. 20 has a configuration similar to that of the reel rotating device 200 including three reel units 210 each having a lighting device 220, like the slot machine 100 described above, and includes a left reel 610, A reel display window 613 is provided through which the middle reel 611 and the right reel 612 face.

  The pachinko machine 600 also has a handle 621, a receiving tray 622 into which a pachinko ball to be launched by an operation on the handle 621 is introduced, and a circular shape in which the pachinko ball is launched so that the player can launch a pachinko ball as a game ball. A game area 623. A nail (not shown) is arranged in the game area 623, and a pachinko ball falling from the upper part of the game area 623 collides with the nail and falls to the lower part of the game area 623 while changing its direction. The game area 623 is provided with a winning opening 624. When a pachinko ball enters the winning opening 624, a predetermined privilege is given to the player.

  For example, when the bonus is selected by winning a lottery, the player is given a chance to pay out a large number of pachinko balls. The display of the lottery result is performed by the rotation / stop control of the reels 610, 611, and 612, and the player can determine from the combination of the stopped patterns that the game is a big hit or miss. Note that the lottery result is displayed by another display means, and the display operation by this display means is shown as the display operation of the reels 610, 611, 612 so as to show the player with a more visual effect. It doesn't matter. In any case, if the reels 610, 611, and 612 that can be visually recognized by the player from the display window 613 can be illuminated by the lighting device 220 described above, the pattern display area corresponding to the stop pattern is illuminated substantially uniformly. It becomes possible to show the player the patterns 611 and 612 effectively.

  FIG. 21 is a functional block diagram of the control unit 700 of the pachinko machine 600 described above. The control unit 700 includes a processing unit 711 such as a CPU, a random number generation unit 712 that generates a random number, a first storage unit 713a such as a RAM that can rewrite the storage content, and a ROM that stores the storage content fixedly. It has the 2nd memory | storage means 713b. The control unit 700 controls the lighting device 720 to illuminate the inner surfaces of the reels 610, 611, and 612, and detects signals from a sensor 730 that is provided at the winning opening 624 and detects the entrance of a pachinko ball.
