[Problems to be solved by the invention]
As a way to make the game surprising, we considered using a liquid crystal display on the entire front decorative panel of the gaming machine so that the score and the hit according to the picture and the situation can be displayed around the translucent part. However, such a display for a game machine has polarizing plates on both sides, and if one polarizing plate is used, natural light is absorbed by about 60% and transmitted light is reduced by about 40%. Further, when the liquid crystal is interspersed with orthogonal Nicols, the transmitted light is lower than 30%. For the reasons described above, the slot display of a game display using this liquid crystal display is observed dimly, so that a linear light source such as a cold-cathode tube or an illumination means including a high-brightness LED or a miniature bulb is used. A large bright light source is required, and the game is hindered, for example, the power consumption increases and the heat generated by the light source deteriorates the liquid crystal display.
[0005]
[Means for Solving the Problems]
As set forth in claim 1, the display of the present invention is a display provided with a pair of polarizing plates so as to sandwich a liquid crystal display cell, wherein at least one of the pair of polarizing plates has a polarizing function. The opening is formed corresponding to a predetermined area of the liquid crystal display cell.
[0006]
As described in claim 2, the display of the present invention includes a pair of polarizing plates sandwiching the liquid crystal display cell, and has a colored transparent or achromatic light transmitting portion at the center of the liquid crystal display cell, In a display device having a display portion whose display content is variable around the light transmitting portion, at least one of the pair of polarizing plates has an opening having no polarizing function corresponding to the light transmitting portion. It is characterized by having been formed.
[0007]
According to a third aspect of the present invention, there is provided a gaming machine having a rotary display body and a decorative board disposed in front of the rotary display body, wherein the decorative board is the claim 1 or the decorative board. The display device described in item 2 is used.
[0008]
According to the present invention, when a liquid crystal display is used for a front decorative panel of a gaming machine using a slot display, by eliminating a polarizing function of a polarizing plate portion covering a plurality of light transmitting portions in a substantially central portion, The slot display is made easier to see by suppressing a decrease in light transmittance due to passing through the polarizing plate.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1A is a plan view of a gaming machine display 1 according to an embodiment of the present invention, and FIG. 1B is a cross-sectional view taken along the line II ′ of FIG. 1A. In FIG. 1, reference numeral 10 denotes a liquid crystal display cell in which two glass sheets 10A are adhered to each other and a liquid crystal 10B is filled therebetween. The gaming machine display 1 is composed of a liquid crystal display cell 10 and a pair of polarizing plates 14 provided outside each glass plate 10A. The size is, for example, 42 cm wide and 26 cm long (corresponding to 19 inches) and 2 mm thick. is there.
[0010]
Reference numeral 11 denotes a light-transmitting portion provided in a predetermined area of the liquid crystal display cell 10 constituting the gaming machine display 1, in this example, substantially at the center. The colored transparent or achromatic translucent portion 11 has a slot display portion (for example, “7”, “7”) composed of a pattern or a number of a rotary display body separately disposed behind the liquid crystal display cell 10 using this portion as a window. It is for visually observing a number such as "7" and a picture such as a bell and a cherry. The translucent section 11 may have the same configuration as the decorative display section 13 described later. However, in order to make it easier to see through the display behind the cell, the light transmittance under the same conditions as the decorative display section 13 is increased. It is preferable to have a configuration. In order to increase the light transmittance, it is preferable that the light transmitting portion 11 selectively lacks a color filter, a switching element, a pixel electrode, and the like. The light-transmitting portion 11 is provided with a plurality of light-transmitting portions 11 having a size of a fraction of the size of the liquid crystal display 1, for example, a size of 8 cm wide and 13 cm (equivalent to 6 inches).
[0011]
It is preferable to provide the light-shielding portion 12 around the light-transmitting portion 11 so that the light-transmitting portion 11 stands out and the player can easily concentrate on the game. In the case where the light-shielding portion 12 is provided, a black matrix of a reflective material or a color filter may be arranged in such a manner that the light-transmitting portion 11 is simply bordered. In a simple manner, the light-shielding portion 12 may be provided in the form of glasses on the back surface of the liquid crystal display.
[0012]
A hatched rectangular portion 13 in FIG. 1A is a decorative display portion provided around the light-transmitting portion 11 of the liquid crystal display cell 10 in the gaming machine display 1. By using a dot matrix liquid crystal display, not only turning on / off a fixed pattern, but also changing the display content with graphic display data, from a gradual demonstration display during standby to a display and game including specific information at the time of game It is possible to display such as a game result at the time of termination, and to elevate the player's feelings.
[0013]
The liquid crystal display cell 10 has a pair of polarizers 14 above and below, and the polarizers are shaped like a square with a hollow center and a hatched area around the center, as shown in FIG. It has an area with functions. Therefore, a large opening 14H having no polarizing function is provided at the same position of the upper and lower polarizing plates 14, 14 in correspondence with the light transmitting section 11. The surface of the polarizing plate is provided with a protective sheet covering the entire display surface to improve the touch feeling. The protective sheet may be formed of an overcoat material or the like.
[0014]
By providing the opening 14H, the polarization characteristics are lost, and almost all of the transmitted light passing through the light transmitting section 11 can be used, so that the center slot display is easy to see. This eliminates the need for a linear light source such as a cold-cathode tube, or a bright large light source such as a high-brightness LED or miniature light bulb, and is adversely affected by increased power consumption and deterioration of the liquid crystal display due to heat generated by the light source. Disappears.
[0015]
In the above embodiment, the case where only one opening 14H of the polarizing plate 14 is common to the plurality of translucent portions 11 is illustrated. However, as shown in FIG. A plurality of light portions may be formed correspondingly. That is, as another method of hollowing out the polarizing plate 16, the polarizing plate 16 may be arranged in a spectacle shape as shown in FIG. 2 even in a portion between the light transmitting portions 15 (a cross-sectional view in FIG. 2 is omitted). In this case, the presence of each of the light shielding portions 17 around the light transmitting portion 15 has an effect that the slot display of the light transmitting portion becomes more prominent.
[0016]
Since an opening is formed in the polarizing plate, a step is generated.As an example of eliminating the polarization characteristic in the light-transmitting portion with a structure without a step, for example, a transparent resin sheet having a similar thickness is inserted in a place where the polarizing plate is hollowed out. is there.
[0017]
Alternatively, a polarizing plate having no steps and partially having no polarizing characteristics is formed by, for example, molding a polarizing sheet in two colors on a transparent resin plate to be hollowed.
[0018]
In the above embodiment, the openings are provided in both of the pair of polarizing plates, but the openings may be provided in only one of the front and back polarizing plates.
[0019]
The display 1 configured as described above is used as a decorative board of a gaming machine such as a slot machine. When used as a decorative board of a slot machine, this indicator is arranged in front of the rotating display of the slot machine so that the rotating indicator can be seen through the opening, and this indicator constitutes the front part of the slot machine. To fix it.
