  The side end of the lower side wall 252A of the upper block BK1 (end on the front side of the reflector 242 on the lower side wall 252A) and the side end of the upper side wall 248B of the middle block BK2 (the end on the front side of the reflector 242 on the upper side wall 248B) In each of these, a plurality of slits 260 are formed in a staggered manner (alternately) along the width direction of the reflector 242. In other words, each of the side end of the lower side wall 252A of the upper block BK1 and the side end of the upper side wall 248B of the middle block BK2 is an area where the slit 260 is formed (the light emitted from the light source). The first attribute region in which the degree of influence on the path is the first degree) and the area where the slit 260 is not formed (the degree of influence on the path of light projected from the light source is the first degree) The second attribute areas having different second degrees), and each of the side edge of the lower side wall 252A of the upper block BK1 and the side edge of the upper side wall 248B of the middle block BK2. Are arranged in a staggered manner in which a region where the slits 260 are formed and a region where the slits 260 are not formed.

  Similarly, the side end of the lower side wall 252B of the middle block BK2 (the front side end portion of the reflector 242 in the lower side wall 252B) and the side end of the upper side wall 248C of the lower block BK3 (the front side of the reflector 242 in the upper side wall 248C) A plurality of slits 260 are also formed in each of the end portions in a staggered manner (alternately) along the width direction of the reflector 242. In other words, each of the side end of the lower side wall 252B of the middle block BK2 and the side end of the upper side wall 248C of the lower block BK3 also has an area where the slit 260 is formed (the light emitted from the light source). The first attribute region in which the degree of influence on the path is the first degree) and the area where the slit 260 is not formed (the degree of influence on the path of light projected from the light source is the first degree) 2nd attribute areas having different second degrees), and each of the side end of the lower side wall 252B of the middle block BK2 and the side end of the upper side wall 248C of the lower block BK3. In addition, a region where the slits 260 are formed and a region where the slits 260 are not formed are arranged in a staggered manner.

  In this embodiment, the slits 260 are formed in a staggered pattern in the partition portion 256. However, the present invention is not limited to this, and the arrangement mode of the first attribute region and the second attribute region at the side end of the lower side wall 252. And the arrangement | positioning aspect of the 1st attribute area | region and the 2nd attribute area | region in the side edge of the upper side wall 248 should just differ.

  Therefore, for example, by making the width of the slit 260 formed at the side end of the lower side wall 252 different from the width of the slit 260 formed at the side end of the upper side wall 248, the slit 260 at the side end of the lower side wall 252 is changed. The arrangement mode of the first attribute area in which the slit 260 is formed and the second attribute area in which the slit 260 is not formed, and the first attribute area and the slit 260 in which the slit 260 is formed at the side edge of the upper side wall 248 are formed. The arrangement pattern of the second attribute areas that are not present may be different. Moreover, the slit 260 is formed at the side end of the lower side wall 252 by making the number of the slits 260 formed at the side end of the lower side wall 252 different from the number of the slits 260 formed at the side end of the upper side wall 248. The arrangement of the first attribute region and the second attribute region where the slit 260 is not formed, and the first attribute region where the slit 260 is formed and the slit 260 are not formed at the side end of the upper side wall 248. The arrangement mode of the two attribute areas may be different. Further, the number of slits 260 formed on the side end of the lower side wall 252 is the same as the number of slits 260 formed on the side end of the upper side wall 248, and the slits 260 are arranged on the lower side wall 252 and the upper side wall 248. By varying the pitch width of the lower side wall 252, the arrangement of the first attribute area in which the slit 260 is formed and the second attribute area in which the slit 260 is not formed at the side end of the lower side wall 252 and the side of the upper side wall 248 The arrangement mode of the first attribute area where the slit 260 is formed and the second attribute area where the slit 260 is not formed may be different at the ends.

  Engaging claws 242A projecting toward the back side are formed on the upper and lower surfaces of the reflector 242, and these engaging claws 242A are engaged with engaging portions 244B formed above and below the illumination board 244. Thus, the illumination board 244 is fixed to the back side of the reflector 242.

  A mounting base 242B is integrally formed on the right side surface of the reflector 242 from the upper part to the lower part. The backlight module 240 is fixed to the mounting plate 232 via the mounting base 242 </ b> B of the reflector 242 and is accommodated in the reel driving unit 200.

  FIG. 9A is an external perspective view of the reflector 242, and FIG. 9B is a partially enlarged view of a region indicated by reference numeral A in FIG. FIG. 4C is a cross-sectional view (cross-sectional view in the longitudinal direction of the slit 260) taken along the line CC in FIG. 4B, and FIG. It is sectional drawing (cross-sectional view of the width direction of the slit 260) which extracted and showed only the vicinity of one slit 260 among the sectional drawings in alignment with -D.

  The slit 260 has a concave groove shape that is formed to communicate from the lower side wall 252 and the upper side surface 248 to the front surface portion (side wall on the reel band 210 side) 256 </ b> A continuous with the lower side wall 252 and the upper side surface 248. Thus, the shortest distance from the region where the slit 260 is formed to the light source (the distance from the light source side end of the slit 260 to the light source) is the shortest distance from the region where the slit 260 is not formed to the light source (front surface portion). The distance from 256A to the light source is different.

  Further, as shown in the DD cross section of FIG. 4D, the upper edge on both sides in the width direction of the slit 260 (the boundary between the region where the slit 260 is formed and the region where the slit 260 is not formed). Is rounded to have a rounded R shape (a shape capable of diffusing light), and this round processing is performed at the end of the slit 260 on the light source side, as shown in FIG. The slit 260 is applied to the entire length of the slit 260 from the end to the end of the reel band 210 side. Further, as shown in the CC cross section of FIG. 4C, the edges on the both sides in the longitudinal direction of the slit 260 (the end on the light source side and the end on the reel band 210 side) are also rounded. A round R shape (a shape capable of diffusing light) is formed, and a cross-sectional view is linear between the light source side end and the reel band 210 side end. As shown in FIG. 4B, the end on the reel band 210 side in the region where the slits 260 are not formed is also rounded to have a rounded R shape (light can be diffused). This round processing is applied to all the ends on the reel band 210 side in the region where the slits 260 are not formed.

<Conventional backlight module>
FIG. 10A is a diagram showing a state of light projected on the reel band 210 by the conventional backlight module 280, and FIG. 10B is a cross-sectional view taken along line CC in FIG. It is sectional drawing which follows.

  The conventional backlight module 280 includes a conventional reflector 282 in which the slits 260 are not formed, and an illumination board 284 having the same configuration as the illumination board 244. The light emitted from a plurality (six in this example) of LEDs 284A provided on the illumination board 284 has its light projection area restricted by the three blocks BK4 to BK6 of the conventional reflector 282, and the front of the reflector 282. To the rear surface of the reel band 210.

  In the conventional backlight module 280, as shown in FIG. 5B, the lower side of the light projection area OP4 that has passed through the upper block BK4 and the light projection area OP5 of the light that has passed through the middle block BK5. The upper side overlaps before the reel band 210 and reaches the back surface of the reel band 210 (the light projection area OP4 that has passed through the upper block BK4 and the light projection area OP5 that has passed through the middle block BK5) The arrangement position of the backlight module 280 with respect to the reel band 210 and the shape of the reflector 282 are designed so that no gap is formed between the light transmission regions. Similarly, the lower side of the light projection area OP5 that has passed through the middle block BK5 and the upper side of the light projection area OP6 that has passed through the lower block BK6 also overlap before the reel band 210, and So as to reach the back surface (so that there is no gap in the light transmission region between the light projection region OP5 that has passed through the middle block BK5 and the light projection region OP6 that has passed through the lower block BK6) The position of the backlight module 280 with respect to the reel band 210 and the shape of the reflector 282 are designed.

  For this reason, a light projection area DOP3 in which the lower side of the light projection area OP4 and the upper side of the light projection area OP5 overlap, and a projection in which the lower side of the light projection area OP5 and the upper side of the light projection area OP6 overlap. The light region DOP4 is adjacent to the light projection regions DOP3 and DOP4 (the light projection region farthest from the light source among the light projection regions where the light projection regions of the plurality of lights do not overlap), When the reel band 210 is viewed from the front side of the slot machine 100, the light projecting areas DOP3 and DOP4 where a plurality of lights overlap are linearly floating and become conspicuous. And there is a problem that it looks bad. In particular, when a lens such as a Fresnel lens that uniformizes the amount of light to be irradiated is used as a light source, there is a problem that such a light projection region where a plurality of lights overlap becomes more conspicuous. Conventionally, such a light projection area where a plurality of lights overlap each other has been hidden by printing or the like, but in recent years, such measures have not been taken in order to improve the appearance of the display. Is the actual situation.

  FIG. 11A is an enlarged view showing the state of light projected onto the reel band 210 by the conventional backlight module 280.

  For example, when the light amount level of the light projecting area in the vicinity of the block BK4 among the light projecting areas (light projecting areas where the light projecting areas do not overlap) generated only by the light passing through the upper block BK4 is expressed by the numerical value 4. As the distance from the block BK4 increases (as the distance from the light source increases), the light amount level gradually decreases as 3 → 2.5 → 2 →. Similarly, the light amount level of the light projecting area (light projecting area where the light projecting areas do not overlap) generated only by the light passing through the middle block BK5 is also set to 4 as the light intensity level of the light projecting area near the block BK5. In other words, as the distance from the block BK5 increases (as the distance from the light source increases), the light amount level gradually decreases as 3 → 2.5 → 2 →.

  On the other hand, the light quantity level of the light projection area DOP3 where the lower side of the light projection area OP4 and the upper side of the light projection area OP5 overlap is the light quantity level below the light projection area OP4 and the light projection area. Since it is the sum of the upper light quantity levels of OP5, for example, the lower light quantity level of the light projection area OP4 is expressed by a numerical value 2.5, and the upper light quantity level of the light projection area OP5 is a numerical value. When expressed by 2.5, the light amount level of the light projection region DOP3 where a plurality of lights overlap can be expressed by the numerical value 5.

  For this reason, in the example shown in FIG. 11A, the light amount level (in this example, the numerical value 5) of the light projection region DOP3 where the lower side of the light projection region OP4 and the upper side of the light projection region OP5 overlap. The difference in the light amount level (in this example, the numerical value 3) of the light projecting area (the light projecting area where the light projecting areas do not overlap) generated only by the light passing through the upper block BK4 adjacent thereto is 2 can be expressed. Similarly, the light amount level of the light projection area DOP3 (in this example, the numerical value 5) and the light projection area generated only by the light passing through the adjacent block BK5 (the light projection areas where the light projection areas do not overlap) are generated. The difference in the light amount level (in this example, the numerical value 3) in the light region can also be expressed by the numerical value 2. Although not shown, the same applies to the light projection region DOP4 in which the lower side of the light projection region OP4 and the upper side of the light projection region OP5 overlap.

<Backlight module of this embodiment>
FIG. 12A is a diagram showing the state of light projected on the reel band 210 by the backlight module 240 of the present embodiment. Moreover, the figure (b) is sectional drawing which follows the AA line in the figure (a), The figure (c) is sectional drawing which follows the BB line in the figure (a).

  The light emitted from a plurality of (six in this example) LEDs 244A provided on the illumination board 244 is reeled from the front of the reflector 242 while its light projection area is regulated by the three blocks BK1 to BK3 of the reflector 242. The light is emitted toward the back surface of the band 210.

  In the backlight module 240 of the present embodiment, as shown in FIG. 4B, the lower side of the light projection area OP1 that has passed through the upper block BK1, and the light transmission area OP2 that has passed through the middle block BK2. So as to overlap the front side of the reel band 210 and reach the back surface of the reel band 210 (light projection area OP1 of light passing through the upper block BK1 and light projection area of light passing through the middle block BK2) The arrangement position of the backlight module 240 with respect to the reel band 210 and the shape of the reflector 242 are designed so that there is no gap in the light projection area between OP2. Similarly, the lower side of the light projection area OP2 that has passed through the middle block BK2 and the upper side of the light projection area OP3 that has passed through the lower block BK3 also overlap in front of the reel band 210 to overlap the reel band 210. The gap between the light projection areas OP2 and the light projection area OP3 that has passed through the lower block BK3 and the light projection area OP3 that has passed through the lower block BK3 is prevented from reaching the back surface. ) The arrangement position of the backlight module 240 with respect to the reel band 210 and the shape of the reflector 242 are designed. Note that it is technically difficult to completely eliminate the gaps between the plurality of light projection areas in consideration of an error in the arrangement position of the backlight module 240, an error in the shape of the reflector 242, and the like. In the example, the design is made so that a plurality of light projection areas are overlapped.

  Therefore, a light projection area DOP1 (DOP11, DOP12) in which the lower side of the light projection area OP1 and the upper side of the light projection area OP2 overlap, and the lower side of the light projection area OP2 and the light projection area OP3. The projection areas DOP2 (DOP21, DOP22) that overlap the upper side of the projection areas are adjacent to these projection areas DOP1 (DOP11, DOP12), DOP2 (DOP21, DOP22) (a plurality of light projection areas do not overlap). The light quantity level is larger than the light projection area (the light projection area farthest from the light source).

  However, in the AA cross section shown in FIG. 4B, the light passing through the upper block BK1 is affected by the slit 260 and changes its traveling direction (the light projection area is slightly changed by the slit 260). However, the light passing through the middle block BK2 is not affected by the slit 260 (the light projection area is not widened by the slit 260), and the light passing through the lower block BK3 is slit. Although the traveling direction changes under the influence of the light 260 (the light projection area is slightly expanded by the slit 260), the light that has passed through the middle block BK2 is not affected by the slit 260 (by the slit 260). The light projection area does not expand).

  On the other hand, in the BB cross section shown in FIG. 5C, the light passing through the middle block BK2 is affected by the slit 260 and changes its traveling direction (the light projection area is slightly changed by the slit 260). However, the light that has passed through the upper block BK1 is not affected by the slit 260 (the light projection area is not widened by the slit 260), and the light that has passed through the middle block BK2 is slit. Although the traveling direction changes under the influence of the light 260 (the light projection area is slightly expanded by the slit 260), the light that has passed through the lower block BK3 is not affected by the slit 260 (by the slit 260). The light projection area does not expand).

  For this reason, in the AA cross section, the lower side of the light projection area OP1 and the upper side of the light projection area OP2 overlap, and the lower side of the light projection area OP2 and the light projection area OP3. The light projection area DOP12 in which the upper side of the light projection area DOP21 overlaps in the vertical direction, and the light projection area DOP12 in which the lower side of the light projection area OP1 and the upper side of the light projection area OP2 overlap in the BB cross section. The vertical position of the light projection area DOP22 where the lower side of the area OP2 and the upper side of the light projection area OP3 overlap is shifted in a staggered manner (staggered) in the width direction of the backlight module 240. Accordingly, the total light amount level of the light projection areas DOP1 (DOP11, DOP12) and DOP2 (DOP21, DOP22) where a plurality of lights overlap is smaller than that of the conventional backlight module 280 (about the measurement result of the actual light amount level). Will be described later).

  FIG. 11B is an enlarged view showing the state of light projected on the reel band 210 by the backlight module 240 of this embodiment.

  For example, when the light level of the light projecting area in the vicinity of the block BK1 among the light projecting areas (light projecting areas where the light projecting areas do not overlap) generated only by the light passing through the upper block BK1 is expressed by the numerical value 4. As the distance from the block BK1 increases (the distance from the light source increases), the light amount level gradually decreases as 3 → 2.5 → 2 →. Similarly, the light amount level of the light projecting area (light projecting area where the light projecting areas do not overlap) generated only by the light passing through the middle block BK2 is also set to 4 as the light intensity level of the light projecting area near the block BK2. In other words, as the distance from the block BK2 increases (as the distance from the light source increases), the light quantity level gradually decreases as 3 → 2.5 → 2 →.

  On the other hand, as described with reference to FIG. 12 above, in the AA cross section, the vertical position of the light projection area DOP11 where the lower side of the light projection area OP1 and the upper side of the light projection area OP2 overlap, In the BB cross section, the vertical position of the light projection region DOP12 where the lower side of the light projection region OP1 and the upper side of the light projection region OP2 overlap is staggered in the width direction of the backlight module 240 (alternately). Therefore, the entire light quantity level in the vicinity of the light projection area DOP1 (DOP11, DOP12) where the lower side of the light projection area OP1 and the upper side of the light projection area OP2 overlap is expressed by the numerical value 4 in general. be able to.

  For this reason, in the example shown in FIG. 11B, the entire light quantity level in the vicinity of the light projection area DOP1 (DOP11, DOP12) where the lower side of the light projection area OP1 and the upper side of the light projection area OP2 overlap (this In the example, the numerical value 4) and the light amount level of the light emitting area (light emitting area where the light projecting areas do not overlap) generated only by the light passing through the upper block BK1 adjacent thereto (in this example, the numerical value) The difference of 3) can be expressed by the numerical value 1. Similarly, the entire light quantity level (in this example, the numerical value 4) in the vicinity of the light projection area DOP1 (DOP11, DOP12) and the light projection area generated only by the light passing through the adjacent middle block BK2 The difference in the light amount level (in this example, the numerical value 3) of the (light emitting region where the light emitting regions do not overlap) can also be expressed by the numerical value 1. Although not shown, the same applies to the light projection area DOP2 (DOP21, DOP22) in which the lower side of the light projection area OP2 and the upper side of the light projection area OP3 overlap.

  That is, in the conventional backlight module 280, the light amount level of the light projecting area where the light emitted from the adjacent light sources overlaps, and the light intensity of the light projecting area which is the light projecting area where the light does not overlap and is farthest from the light source. The difference in level can be expressed by the numerical value 2. On the other hand, in the backlight module 240 of the present embodiment, the light amount level of the light projecting area where the light emitted from the adjacent light sources overlaps the light level where the light does not overlap. The difference in the light amount level of the light projecting region that is the farthest from the light source in the light region can be expressed by the numerical value 1. Therefore, in the backlight module 240 of the present embodiment, the amount of light between the light projecting area where the light emitted from the adjacent light sources overlaps and the light projecting area where the light does not overlap and which is farthest from the light source. The difference can be made smaller than before.

<Brightness measurement experiment>
Next, an experiment of luminance measurement performed using the conventional backlight module 280 and the backlight module 240 of the present embodiment will be described with reference to FIG.

In this experiment, the luminance of light observed in the reel band 210 was measured using a luminance measuring device (not shown). The lateral width of the reel band 210 is 80 mm, and a position 5 mm in the horizontal direction from one side is set as a reference position in the horizontal direction. From this reference position in the horizontal direction, a position 5 mm in the horizontal direction, a position 15 mm in the horizontal direction, and a position 25 mm in the horizontal direction. A total of seven positions including a position, a position in the horizontal direction of 35 mm, a position in the horizontal direction of 45 mm, a position in the horizontal direction of 55 mm, and a position in the horizontal direction of 65 mm were set as the measurement positions in the horizontal direction. Further, the vertical intermediate position between two adjacent upper and lower blocks is defined as a vertical measurement position 3, with the vertical measurement position 3 used as a reference, the upper 5 mm position is the vertical measurement position 2, and the upper 5 mm position is the vertical measurement position. The direction measurement position was 1. Further, with the vertical measurement position 3 as a reference, the position 5 mm in the downward direction was defined as the vertical measurement position 4 and the position 5 mm in the downward direction was defined as the vertical measurement position 5. Further, in this experiment, for each of the seven measurement positions in the horizontal direction, the measurement of light luminance is performed at five measurement positions 1 to 5 in the vertical direction (7 horizontal positions × 5 vertical positions = total 35 positions). Went. The measurement of the intensity of the light was performed in the dark (2cd / ^{m 2} or less).

  Further, based on the measurement result of luminance, the difference in luminance between adjacent vertical measurement positions was calculated. Specifically, reference symbol A (1-2 difference) in the figure is a difference in luminance between the vertical measurement position 1 and the vertical measurement position 2 at the same horizontal measurement position, and reference symbol B ( 2-3 Difference) is the difference in luminance between the vertical measurement position 2 and the vertical measurement position 3 at the same measurement position in the horizontal direction. Moreover, the code | symbol C (3-4 difference part) in the figure is a brightness | luminance difference of the vertical direction measurement position 3 and the vertical direction measurement position 4 in the same measurement position of a horizontal direction, and code | symbol D (4-5 in the figure) Difference) is a difference in luminance between the vertical measurement position 4 and the vertical measurement position 5 at the same measurement position in the horizontal direction. Furthermore, the AB difference in the figure is the difference between A (1-2 difference) and B (2-3 difference), and the BC difference in the figure is B (2-3 difference). Min) and C (3-4 difference), and the CD difference in the figure is the difference between C (3-4 difference) and D (4-5 difference).

<No slit, no overlap>
FIG. 6A shows that a conventional backlight module 280 (without slits) having no slits is used to prevent a light projection region where light passing through two adjacent upper and lower blocks (for example, BK3 and BK4) overlaps. The measurement result of the brightness | luminance in the case of comprising (no overlap) is shown.

Here, for example, when paying attention to the measurement position of 5 mm in the horizontal direction, the luminances of the vertical measurement positions 1 to 5 at the measurement position of 5 mm in the horizontal direction are 640.9 cd / m ² , 571.1 cd / m ² , 220. 8 cd / m ² , 562.6 cd / m ² , 636.4 cd / m ² . As a result of the measurement, if the horizontal position of the reel band 210 is the same, the luminance at the vertical measurement position 3 that is the farthest from the adjacent two upper and lower blocks is the smallest, and gradually increases as it approaches the block. This is the same for other lateral measurement positions 15 mm, 25 mm, 35 mm, 45 mm, 55 mm, and 65 mm.

Further, for example, when attention is paid to the vertical measurement position 1, the luminance in the horizontal direction of 5 mm to 65 mm at the vertical measurement position 1 is 640.9 cd / m ² , 943.4 cd / m ² , 1237.9 cd / m ² , respectively. 1347.1 cd / m ² , 1215.2 cd / m ² , 931.7 cd / m ² , and 631.8 cd / m ² . As a result of the measurement, when the vertical position of the reel band 210 is the same, the luminance at the center in the horizontal direction (35 mm in the horizontal direction) of the reel band 210 is the highest, and from the horizontal center (35 mm in the horizontal direction) of the reel band 210. This shows that the luminance gradually decreases as the distance increases, and the same applies to the other longitudinal measurement positions 2 to 5.

Further, for example, when focusing attention on A (1-2 difference), the difference in the horizontal direction of 5 mm to 65 mm is 69.8 cd / m ² , 103.3 cd / m ² , 141.5 cd / m ² , 151. 4 cd / m ² , 135.0 cd / m ² , 92.6 cd / m ² , and 67.1 cd / m ² . This calculation result shows that the difference in luminance in the vertical direction at the horizontal center (35 mm in the horizontal direction) of the reel band 210 is the largest, and the difference in luminance in the vertical direction gradually decreases as the distance from the horizontal center of the reel band 210 increases. The same applies to the other B (2-3 difference), C (3-4 difference), and D (4-5 difference). When A (1-2 difference), B (2-3 difference), C (3-4 difference), and D (4-5 difference) are compared, A (1-2 difference) and It can be seen that the numerical values of B (2-3 difference) and C (3-4 difference) are larger than D (4-5 difference). This indicates that the greater the distance from the block, the greater the difference in brightness.

Further, for example, when attention is paid to the AB difference, the difference in the lateral direction of 5 mm to 65 mm is 280.5 cd / m ² , 381.2 cd / m ² , 516.9 cd / m ² , 554.9 cd / m, respectively. ² , 513.2 cd / m ² , 400.1 cd / m ² , 279.1 cd / m ² . This calculation result shows that the difference in luminance in the vertical direction at the horizontal center (35 mm in the horizontal direction) of the reel band 210 is the largest, and the difference in luminance in the vertical direction gradually decreases as the distance from the horizontal center of the reel band 210 increases. The same applies to the CD difference. On the other hand, paying attention to the BC difference, the difference in the lateral direction of 5 mm to 65 mm is 8.5 cd / m ² , 17.2 cd / m ² , 13.7 cd / m ² , 11.0 cd / m ² , respectively. 18.9 cd / m ² , 23.8 cd / m ² , 46.6 cd / m ² . This calculation result indicates that the difference in luminance in the vertical direction does not depend on the position in the horizontal direction.

<No slit, with overlap>
In FIG. 6B, a conventional backlight module 280 without slits (without slits) is used so that a light projecting region where light passing through two adjacent upper and lower blocks (for example, BK3 and BK4) overlaps is generated. The measurement result of the brightness | luminance when it comprises (with overlap) is shown.

Here, for example, when paying attention to the measurement position of 5 mm in the horizontal direction, the luminances of the vertical measurement positions 1 to 5 at the measurement position of 5 mm in the horizontal direction are 626.2 cd / m ² , 558.4 cd / m ² , and 798. ^{2cd / m 2, 534.8cd / m} 2, a 634.4cd / ^{m 2.} As a result of this measurement, if the position of the reel band 210 in the horizontal direction is the same, the vertical measurement position 3 (the light passing through the two adjacent upper and lower blocks overlaps the farthest from the two adjacent upper and lower blocks). This is the same for the other horizontal measurement positions 15 mm, 25 mm, 35 mm, 45 mm, 55 mm, and 65 mm. As a result of this experiment, in the conventional backlight module 280, when the reel band 210 is viewed from the front side of the slot machine 100, the light projecting areas DOP3 and DOP4 where a plurality of lights overlap are linearly floated and become conspicuous. This confirms the problem of poor appearance.

Further, for example, when paying attention to the vertical measurement position 1, the luminance in the horizontal direction of 5 mm to 65 mm at the vertical measurement position 1 is 626.2 cd / m ² , 938.6 d / m ² , 1226.3 d / m ² , respectively. 1332.6 cd / m ² , 1223.5 cd / m ² , 913.0 cd / m ² , 613.6 cd / m ² . As in the case of <no slit, no overlap>, the measurement result shows that the luminance at the center in the horizontal direction (35 mm in the horizontal direction) of the reel band 210 is the highest when the vertical position of the reel band 210 is the same. This shows that the luminance gradually decreases as the distance from the center in the horizontal direction of the reel band 210 increases, and the same applies to the other measurement positions 2 to 5 in the vertical direction.

Further, for example, when focusing attention on A (1-2 difference), the difference in the horizontal direction of 5 mm to 65 mm is 67.8 cd / m ² , 122.4 cd / m ² , 132.0 cd / m ² , and 137. 8 cd / m ² , 138.6 cd / m ² , 110.8 cd / m ² , 50.2 cd / m ² . This calculation result shows that the difference in luminance in the vertical direction near the horizontal center (25 mm, 35 mm, 45 mm) of the reel band 210 is larger than the others, and gradually increases in the vertical direction as the distance from the horizontal center of the reel band 210 increases. This shows that the difference in luminance is small, and the same applies to D (4-5 differences). On the other hand, for example, when attention is paid to B (2-3 difference), the difference in the horizontal direction of 5 mm to 65 mm is 239.9 cd / m ² , 260.9 cd / m ² , 233.0 cd / m ² , 204. 6 cd / m ² , 237.3 cd / m ² , 319.9 cd / m ² , and 241.8 cd / m ² . This calculation result indicates that the difference in luminance in the vertical direction does not depend on the position in the horizontal direction, and the same applies to B (3-4 difference).

  When A (1-2 difference), B (2-3 difference), C (3-4 difference), and D (4-5 difference) are compared, A (1-2 difference) and It can be seen that the numerical values of B (2-3 difference) and C (3-4 difference) are larger than D (4-5 difference). This indicates that the greater the distance from the block, the greater the difference in brightness.

For example, when attention is paid to the AB difference, the differences in the horizontal direction of 5 mm to 65 mm are 172.0 cd / m ² , 138.6 cd / m ² , 101.0 cd / m ² , and 66.8 cd / m, respectively. ² , 98.7 cd / m ² , 209.1 cd / m ² , 191.6 cd / m ² . This calculation result shows that the difference in luminance in the vertical direction does not depend on the position in the horizontal direction, and this is the same for other BC differences and CD differences.

<With slit, with overlap>
FIG. 6C shows that the backlight module 240 (with slits) of the present embodiment having the slit 260 is used to generate a region where light passing through two adjacent upper and lower blocks (for example, BK1 and BK2) overlap. The measurement result of the brightness | luminance in the case of comprising (with overlap) is shown.

Here, for example, when paying attention to the measurement position of 5 mm in the horizontal direction, the luminances of the vertical measurement positions 1 to 5 at the measurement position of 5 mm in the horizontal direction are 636.8 cd / m ² , 562.6 cd / m ² , and 474. 3 cd / m ² , 566.9 cd / m ² , 639.7 cd / m ² . As in the case of <no slit, no overlap>, the measurement result indicates that the distance from the adjacent two upper and lower blocks is the longest in the vertical direction when the reel band 210 has the same horizontal position. 3 indicates that the luminance is the smallest and gradually increases as the block is approached, and the same applies to other lateral measurement positions 15 mm, 25 mm, 35 mm, 45 mm, 55 mm, and 65 mm.

Further, for example, when paying attention to the vertical direction measurement position 1, the luminance in the horizontal direction of 5 mm to 65 mm at the vertical direction measurement position 1 is 636.8 cd / m ² , 941.0 cd / m ² , 1235.7 cd / m ² , respectively. 1341.4 cd / m ² , 1227.8 cd / m ² , 930.8 cd / m ² , and 622.4 cd / m ² . As in the case of <no slit, no overlap> and <no slit, with overlap>, the measurement result indicates that if the vertical position of the reel band 210 is the same, the horizontal center of the reel band 210 (horizontal The luminance in the direction (35 mm) is the largest, and the luminance gradually decreases as the distance from the lateral center of the reel band 210 is increased. The same applies to the other vertical measurement positions 2 to 5.

Further, for example, when focusing on A (1-2 difference), the difference in the lateral direction of 5 mm to 65 mm is 74.2 cd / m ² , 101.1 cd / m ² , 142.4 cd / m ² , 147. ^{5cd / m 2, 157.1cd / m} 2, 92.9cd / m 2, a 69.4cd / ^{m 2.} As in the case of <No slit, with overlap>, the calculation result shows that the difference in luminance in the vertical direction in the vicinity of the center in the horizontal direction (25 mm, 35 mm, 45 mm) of the reel band 210 is larger than the others. This indicates that the luminance difference in the vertical direction gradually decreases as the distance from the horizontal center of 210 decreases, and other B (2-3 difference), C (3-4 difference), D (4-5) The same applies to the difference).

  On the other hand, in the above <No slit, no overlap> and <No slit, overlap>, the numerical values of A (1-2 difference) and D (4-5 difference) are B (2-3 difference). And C (3-4 difference) are greatly different from each other, and there is a tendency that the difference in luminance increases as the distance from the block increases. In the case of <with slit, with overlap>, A (1-2 The difference between the numerical value of (difference) or D (4-5 difference) and the numerical value of B (2-3 difference) or C (3-4 difference) is small. The calculation results are as follows: <With slit, with overlap> Compared with <Without slit, without overlap> and <With no slit, with overlap> at all measurement positions in the lateral direction of the reel band 210 from 5 mm to 65 mm. The difference between the brightness of the light projecting area where the light passing through two adjacent upper and lower blocks overlap and the brightness of the other light projecting areas (light projecting areas where a plurality of lights overlap) is reduced. ing.

For example, when attention is paid to the AB difference, the difference in the lateral direction of 5 mm to 65 mm is 14.2 cd / m ² , 5.8 cd / m ² , 18.4 cd / m ² , 57.5 cd / m, respectively. ² , 9.3 cd / m ² , 19.4 cd / m ² , 11.4 cd / m ² . This calculation result shows that, in the case of <with slit, with overlap>, two adjacent upper and lower blocks are measured at all measurement positions in the horizontal direction of 5 mm to 65 mm of the reel band 210 as compared with the case of <without slit, without overlap>. This shows that the difference between the luminance of the light projecting area where the passing light overlaps and the brightness of the other light projecting areas (light projecting areas where the plurality of lights do not overlap) is small.

In the above <no slit, no overlap>, the difference in luminance in the vertical direction at the horizontal center of the reel band 210 (35 mm in the horizontal direction) is the largest, and the luminance in the vertical direction gradually increases as the distance from the center of the reel band 210 increases. Although the difference was small, in the case of <with slit, with overlap>, the AB difference in the horizontal direction 35 mm (57.5 cd / m ² ) → the AB difference in the horizontal direction 55 mm (19.4 cd / m) ² ) → 25 mm AB difference (18.4 cd / m ² ) → AB difference 5 mm (14.2 cd / m ² ) → 65 mm AB difference (11 mm) .4 cd / m ² ) → AB difference of 45 mm in the horizontal direction (9.3 cd / m ² ) → AB difference of 15 mm in the horizontal direction (5.8 cd / m ² ) It has become. This indicates that the difference in luminance in the horizontal direction in the reel band 210 is smaller in <with slit and with overlap> than in the case of <without slit and without overlap>. The same applies to the C difference and the CD difference.

  As a result of the experiment with <with slit, with overlap>, in the backlight module 240 of this embodiment, the total light amount level of the light projection areas DOP1 and DOP2 in which a plurality of lights overlap is higher than that of the conventional backlight module 280. It confirms that it is getting smaller.

<Main control unit main processing>
Next, the main process of the main control unit 300 will be described with reference to FIG. FIG. 3 is a flowchart showing the flow of main processing of the main control unit 300.

  Basic control of the game is performed mainly by the CPU 310 of the main controller 300, and the CPU 310 repeatedly executes the main process of the main controller shown in FIG.

  When power is turned on to the slot machine 100, first, various initialization processes are executed in step S101 of the main control unit main process, and then, in step S102, a process related to medal insertion is performed. Here, it is checked whether or not medals have been inserted, and the winning line display lamp 120 is turned on according to the number of medals inserted. In the case where the player has won the re-game player in the previous game, the same number of bets as the previous game can be played without additional insertion of medals. In step S102, a process related to a game start operation is performed. Here, it is checked whether or not the start lever 135 has been operated. If it is determined that the start operation has been performed, the number of inserted medals is determined and a start signal (command) is transmitted to the sub-control unit 400. To do.

  In step S103, the valid line is determined, and in step S104, the random number generated by the random number generator 317 is acquired.

  In step S105, an internal lottery of the winning combination is performed using the random number value acquired in step S104 and the winning combination lottery table stored in the ROM 312. Also, in this step S105, if it is determined that any winning combination has been won internally as a result of the winning combination internal lottery, if it is determined that the command corresponding to the winning combination is lost (no winning combination) Transmits a command corresponding to the loss to the sub-control unit 400.

  In step S106, reel stop data candidates are selected based on the internal lottery result in step S105. In step 107, rotation of all the reels 110 to 112 is started by a reel rotation start process.

  In step S108, a reel stop control process is performed. In this reel stop control process, after the reel stop data actually used for the reel stop control is determined from the plurality of reel stop data candidates selected in step S106 according to the stop order and the stop situation of the reels 110 to 112, Based on the determined reel stop data, the rotation of the reels 110 to 112 corresponding to the pressed stop buttons 137 to 139 is stopped.

  In step S109, the winning determination of the symbols stopped when the stop buttons 137 to 139 are pressed is performed. Here, when the symbol combination corresponding to the winning combination internally or the winning combination is displayed (displayed) on the active line, it is determined that the winning combination has been won. For example, if “replay-replay-replay” is arranged on the active line, it is determined that the replay is won. In step S109, when it is determined that the winning combination is won as a result of the winning determination, a command corresponding to the winning combination is transmitted to the sub-control unit 400.

  In step S110, a medal payout process is performed. In this medal payout process, if a winning combination with a payout is won, the number of medals corresponding to the winning combination is paid out. In step S111, game state control processing is performed. Thus, one game is completed, and thereafter, the game proceeds by repeating the main control unit main process.

  As described above, the slot machine 100 according to the present embodiment is provided with a light source (for example, a plurality of LEDs 244A) that emits light and game information (for example, symbols) related to the game, and transmits light from the light source. A first light projecting region of light that projects from the light source side toward the light transmissive member and is projected from the light source toward the light transmissive member; A partition member (e.g., a partition portion 256) that separates the light projecting region and the second light projecting region, and the partition member regulates a first side wall (e.g., lower wall) that regulates the light path of the first light projecting region. A side wall 252) and a second side wall (for example, an upper side wall 248) that regulates the light path of the second light projecting region, and a side end of the first side wall on the light transmitting member side, and The light transmitting member side on the second side wall Each of the side ends has a first attribute region (for example, a slit) in which the degree of influence on the light projection region of light projected from the light source is the first degree (for example, widens the light projection region). 260) and a second degree different from the first degree in the degree of influence on the light projection area of the light projected from the light source (for example, the light projection area) A second attribute region (for example, a region where the slit 260 is not formed), and an arrangement mode of the first attribute region and the second attribute region at a side end of the first sidewall is It is a gaming machine characterized in that it is different from the arrangement mode of the first attribute area and the second attribute area at the side end of the second side wall (for example, both are arranged in a staggered manner).

  In other words, the slot machine 100 according to the present embodiment is provided with a light source (for example, a plurality of LEDs 244A) that emits light and game information (for example, symbols) relating to the game, and can transmit light from the light source.
