[3. Liquid crystal display device of display panel DP]
Next, the liquid crystal display device of the display panel portion DP in the present embodiment and the light guide plate included in the liquid crystal display device will be described with reference to FIGS.

  FIG. 4 is an exploded perspective view of the liquid crystal display device of the display panel portion DP of the present embodiment. As shown in the figure, a liquid crystal display device L protected by an acrylic plate AC is provided from the back side of the front door 3 in the frame of the central opening of the front door 3. The liquid crystal display device L includes a liquid crystal panel LC, an optical sheet LS, a light guide plate LG, and a linear light source portion LD that supplies light to the light guide plate LG, and includes two frame members CV1 and CV2 that are fitted together. These are fixed inside.

In this device, the light emitted from the backlight is modulated to display an image.

  Next, the backlight according to the present embodiment is a so-called sidelight-type backlight including the light guide plate LG, the linear light source unit LD, and the optical sheet LS. First, the linear light source unit LD is configured by arranging, for example, a plurality of LED (Light Emitting Diode) elements in a straight line, and is disposed above the light guide plate LG.

  Next, the light guide plate LG is made of a transparent resin such as acrylic, and has a function of converting light emitted from the LED element into a surface light source. Details of the light guide plate LG will be described later.

  The optical sheet LS is an optical member disposed between the light guide plate LG and the liquid crystal panel LC, and is configured by, for example, a prism sheet or a diffusion sheet. Although one optical sheet LS is disclosed in FIG. 4, a plurality of optical sheets may be arranged.

[3-1. About light guide plate]
Hereinafter, the light guide plate LG in the present embodiment will be described in detail. In the light guide plate LG, the hollow variable opening OP is formed at a position corresponding to the reel window 20, so that the reel variable display device RL can be clearly seen from the inside of the reel window 20. However, as already described with reference to FIG. 8, since light emission from the linear light source part LD is blocked at each upper side of the opening OP, the amount of emitted light is emitted in a region below each lower side of the opening OP. The part where there is less is generated.

  FIG. 5 is a diagram for specifically explaining the configuration of the light guide plate LG of the present embodiment. FIG. 5A shows a state of the light guide plate LG according to this embodiment. The light guide plate LG of the present embodiment has a light guide direction conversion portion TL at a position below the opening OP on the side surface on the left side when viewed from the front. As shown in FIG. 5B, the incident light guided from the linear light source part LD to the light guide direction changing part TL is in a region where light emission from the linear light source part LD is blocked by the opening OP. Therefore, it is possible to suppress the occurrence of unevenness in the amount of emitted light that occurs below the opening OP.

  FIG.5 (c) is a figure for demonstrating in detail the light guide plate LG of this embodiment, and the light guide plate LG is the light guide maintenance part KL provided with the light guide direction conversion part TL, and an image display corresponding | compatible part. It is configured to include a DI, an incident end IE where light emitted from the linear light source unit LD is incident, and an opposing end FE facing the incident end IE.

  As shown in the figure, the light guide maintaining portion KL includes a side surface formed perpendicularly between the incident end portion IE and the opposite end portion FE, and faces the incident end portion IE along the side surface. The portion extends toward the end FE. From another viewpoint, the light guide maintaining portion KL is a portion that extends in a strip shape adjacent to the reel display 20 and the image display corresponding portion DI that displays an image corresponding to the upper, lower, left, and right outer peripheral regions. It has become.

  And the light guide maintenance part KL is extended in the position of the opposing edge part FE side rather than each opening part OP, and has the light guide direction conversion part TL in the said position. The light guide direction conversion part TL includes an inclined side surface that is inclined so as to approach the opening OP side (in the case of FIG. 5C, the right side) as it proceeds toward the opposing end FE side. The direction of the principal ray in the light guide maintaining portion KL that travels substantially perpendicularly with respect to the linear light source part LD is converted and guided to a region where light emission from the linear light source part LD is blocked by the opening OP. It has become so.

  Further, the light guide maintaining part KL extends on the side of the image display corresponding part DI corresponding to the image display area 30 for displaying an image to the player, and the front side of the light guide maintaining part KL is The liquid crystal panel LC does not correspond to the image display area 30. Further, it is desirable that the light guide maintaining portion KL does not emit light to the front surface side, but at least the amount of light emitted from the front surface of the light guide maintaining portion KL per unit area is that of the image display corresponding portion DI. It is preferable to reduce the amount of emitted light per unit area. By doing in this way, the amount of light incident from the incident end portion IE of the light guide maintaining portion KL is maintained until reaching the light guide direction converting portion TL, and the light emission from the linear light source portion LD is blocked. The amount of light supplied to the light source can be increased to suppress unevenness in the amount of emitted light.

  Specifically, the light guide maintaining portion KL is configured such that the arrangement density of the light emitting means composed of scattering dots or the like is smaller than that of the image display corresponding part DI (or the light emitting means is not arranged), Further, as will be described later, the front side of the light guide maintaining portion KL is not exposed by the frame-like structure in the electric decoration LED 31 or the front door 3.

  In addition, the light guide direction conversion unit TL is configured to have a shape in which a part of the rectangular light guide plate LG is cut obliquely, and the light guide maintaining portion KL is a principal ray (line) from the incident end IE. Light beam traveling in the vertical direction with respect to the light source unit LD) is a portion that is received by the inclined side surface of the light guide direction conversion unit TL, and is configured to be tapered by the light guide direction conversion unit TL.

  By applying the light guide plate LG having the light guide maintaining portion KL and the light guide direction changing portion TL as described above to the liquid crystal display device L of the front door 3, light is emitted from only one side by the linear light source portion LD. Even when the light is incident, it is possible to suppress the generation of a region with a small amount of emitted light due to the opening OP.

  FIG. 6 is an enlarged view of the light guide direction converting portion TL in the light guide plate LG of the present embodiment. As shown in FIG. 6A, the light guide direction conversion unit TL uses the vertical light guide direction as a reference (based on the linear light source unit LD) with respect to the top plate or bottom surface of the gaming machine housing 2 as a reference. As shown in FIG. Further, the angle θ is preferably 10 degrees or more and 25 degrees or less, and more preferably 13 degrees or more and 20 degrees or less.

  Further, as shown in FIG. 6B, a step-like prism is formed on the inclined side surface of the light guide direction changing portion TL, so that light can be efficiently guided to the lower side of the opening OP. Like that. Moreover, you may make it form a reflective sheet in the inclined side surface of the light guide direction conversion part TL.

  FIG. 7 is a view for explaining the state of the light guide plate LG and the liquid crystal panel LC attached to the front door 3 in the present embodiment, and the structure of the frame body in the front door 3 and the light guide maintenance in the light guide plate LG. The positional relationship among the portion KL, the liquid crystal panel LC, and the image display area 30 is described.

  As shown in FIG. 7A, the light guide maintaining portion KL and the light guide direction changing portion TL in the light guide plate LG are located on the back side of the frame body to which the electrical LED 31 and the electrical LED 31 are attached. The light guide maintaining portion KL is hidden from the player by the illumination LED 31 or the like. Since the light guide maintaining portion KL is arranged in this way, it is desirable that the light guide maintaining portion KL should not emit light emitted from the linear light source part LD on the front side. Further, the light guide plate LG in the present embodiment is configured such that the light guide maintaining portion KL protrudes outside the liquid crystal panel LC so that the light guide maintaining portion KL does not overlap with the image display region 30.

  FIG. 7B is a diagram illustrating a state of the light guide plate LG and the liquid crystal panel LC according to the modification of the present embodiment. The configuration of the modified example in FIG. 7B is different from that in FIG. 7A in that the light guide maintaining portion KL in the light guide plate LG overlaps with the frame region that is a part of the liquid crystal panel LC. The other parts are the same except for the points. As shown in FIG. 7A and FIG. 7B, the linear light source part LD is arranged so as to exceed the side with respect to the image display region 30, and this excess part depends on the excess part. Light emission is incident on the light guide maintaining portion KL and contributes to emission from below the opening OP. By configuring the light guide plate LG and the like in this way, the layout on the back side of the front door 3 can be made efficient. Moreover, when the linear light source part LD is arrange | positioned above the light-guide plate LG, a heat countermeasure becomes easy.

[Others]
Note that the reel window 20 of the display panel portion DP of the above embodiment is formed at three locations corresponding to the three reels R1 to R3 of the variable reel display device RL, but the three reels R1. It may be configured by one reel window 20 that visually recognizes R3.

  In the display panel portion DP of the above-described embodiment, the image display area 30 by the liquid crystal panel LC is expanded so as to surround the inside and outside of the reel window 20. In the area within the reel window 20, the reel variable display is performed. The light from the backlight device 53 in the device RL is modulated by the liquid crystal panel LC so that an image is displayed. In addition, when an image is displayed in the reel window 20, the image is displayed so as to overlap the reel band 58, and the image display is different from the area around the reel window 20. The display panel DP preferably has the reel window 20 disposed in the image display area 30 so that an image can be displayed in the reel window 20 in this way. For example, the image by the liquid crystal panel LC may not be always displayed in the reel window 20, or the liquid crystal panel LC having no image display function in the area of the reel window 20 may be adopted. Thus, the reel window 20 may be arranged in the image display area 30.

  In addition, as for the optical sheet LS used in the above embodiment, it is desirable that an opening be formed in a corresponding region of the reel window 20 as in the light guide plate LG, but a hollow opening may not necessarily be formed. For example, an optical sheet from which the function (prism function, diffusion function, etc.) of the optical sheet is removed in the region corresponding to the reel window 20 may be used.

  In the above embodiment, the incident end IE where the linear light source part LD is disposed corresponds to the upper side of the light guide plate LG, the opposing end FE corresponds to the lower side, and the light guide maintaining part KL is the left side. However, the present invention is not necessarily limited to this mode. For example, the incident end IE may correspond to the lower side of the light guide plate LG, or may correspond to the left side or the right side. . When the incident end IE corresponds to the left side of the light guide plate LG, the opposing end FE corresponds to the right side, and the light guide maintaining portion KL is at a position corresponding to at least one of the upper side or the lower side of the light guide plate LG. To be formed.

  The inclined side surface of the light guide direction conversion unit TL may be configured to reach the opposing end FE, or may be configured not to reach the opposing end FE.

  As shown in FIG. 8, as the distance from the lower side of the opening OP (side on the opposite end FE side) increases, light guides wrap around from both the left and right sides of the opening OP. The decrease in the amount of emitted light is alleviated. As the light guide plate LG, for example, the opening OP may be formed further downward (on the opposite end FE side) so that the light guide wraparound region does not exist further below the light emission blocking region SH. The OP may be formed further upward so that the light guide wraparound region is wide. In addition, the light guide direction conversion unit TL is configured such that the lower end thereof is positioned below the light emission blocking region SH or above the light guide wrapping region so that light emitted from the linear light source unit LD is guided to the light guide blocking region. It is desirable to preferentially guide to SH.

  In the above embodiment, scattering dots as light emitting means are formed on the light guide plate LG. The scattering dots are formed of, for example, a circular printed material having a refractive index different from that of the light guide plate, and the light emitted from the linear light source part LD is diffusely reflected by being incident on the scattering dots and emitted from the front side of the light guide plate LG. Is prompted. The light emitting means may not be a scattering dot pattern. For example, a fine prism may be formed on the back surface of the light guide plate LG to promote emission from the front surface.

  The light emitting means is arranged so that its density improves as it proceeds from the incident end IE to the opposite end FE, so that the opposite end of the opening OP is larger than the portion on the incident end IE side. The density of the light emitting means is higher in the part on the part FE side. Further, the light emitting means in the light emission blocking region SH is a region where the light emission from the incident end IE is not blocked by the opening OP, and the distance from the incident end IE is the same as the light emission blocking region SH. It arrange | positions so that a density may become higher than the light-projection means.

  In addition, although the light guide direction conversion unit TL in the above embodiment is configured to include an inclined side surface as shown in FIG. 6, the inclined side surface may be formed in a curved surface shape or a prism is formed. The inclination angle of the inclined side surface may change in two steps.

  Needless to say, the present invention is not limited to the above-described embodiments, and various modifications are possible.
