Description

Description: TECHNICAL FIELD The present invention relates to a display device of a pachinko machine.

(Prior Art) Conventionally, in a pachinko machine, when a specific winning opening is won, the design (numbers, characters, patterns, etc.) of the display device fluctuates, and if a specific combination is obtained at the time of stoppage, a big hit or a small hit occurs. It becomes a hit. There is a so-called fever type. Display devices used in these types incorporate a display panel inside,
The above-mentioned symbols are variably displayed on this screen.

It is desired that such a display panel has low power consumption and is compact in structure. In these respects, liquid crystal display panels are excellent, and are widely used in general display panels.

However, since the liquid crystal display panel itself is non-luminous, there is a problem that the screen is dark and the pattern on the screen is difficult to see due to insufficient contrast. Therefore, even if the present invention is applied to a pachinko machine as it is, the displayed symbol lacks sharpness and the expression power of the symbol is impaired. Since the display device is an important element for increasing the fun of the game, some countermeasures are required. Therefore, as a countermeasure, it is conceivable to set a backlight light source such as a fluorescent lamp on the back side of the liquid crystal display panel.

(Problem to be Solved by the Invention) As a specific example, there is a configuration in which a fluorescent lamp is set as a backlight light source and the fluorescent lamp is arranged on the back side of a liquid crystal panel. However, in such a configuration, since the fluorescent lamp itself is a component requiring an installation space in the depth direction, the entire display device has a considerable thickness. For this reason, the handling of the display device alone becomes inconvenient, and when the display device is incorporated in a pachinko machine, the amount of protrusion rearward increases, which may cause a collision during transportation.

Further, since the fluorescent lamp is a linear light source, it is difficult to arrange the fluorescent lamp so as to uniformly irradiate the entire surface of the liquid crystal panel, resulting in uneven brightness.

Furthermore, since the luminescent color of the fluorescent lamp does not provide a vivid color display, it cannot be said that it is enough to make the displayed pattern stand out in color, and it is not satisfactory in terms of increasing the fun of the game.

The present invention has been made in view of the above problems, and has as its object to provide a display device that has a compact configuration and is rich in the expressiveness of symbols.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a display device mounted on a game board of a pachinko machine, wherein a transmissive liquid crystal display panel variably displaying a predetermined symbol, An electroluminescence panel for a backlight that irradiates the liquid crystal display panel from almost the entire rear surface thereof is provided, and the electroluminescence panel is divided into a plurality of regions so as to be selectively blinkable and displayable. It is characterized by the following.

(Operation) According to the above configuration, the EL panel serves as a surface light source for the liquid crystal display panel, so that the contrast between the pattern displayed on the liquid crystal display panel and its background is enhanced.

(Example) Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

First, a pachinko machine to which the display device is attached will be described with reference to FIG. Various winning ports are arranged on the game board 1, and 2-5 of them are ordinary winning ports,
Reference numeral 8 denotes a starting port for starting the change of symbols on the display device 9 described below. Then, when a symbol (a three-digit number displayed on the liquid crystal display panel LCP) variably displayed on the display device 9 in accordance with the winning of one of the starting ports 6 to 8 stops after a predetermined time has elapsed. If a specific symbol has been obtained (when three numbers 7 are arranged in a row), a "winning state" is set and the special winning opening 10 arranged below the display device 9 is opened for a predetermined time. It is set.

 In addition, 11-11 are windmills.

The display device 9 arranged substantially at the center of the game board 1
It has a case body 12 as shown in FIG.
The housing 14 of the case main body 12 is fitted into a mounting hole 13 opened in the game board 1, and the entire mounting is performed. The housing 14 is formed in a rectangular tube shape that opens in both front and rear directions, and a transparent cover plate is provided on the front opening article.
15 is inserted from the inside.

Inside the housing 14, a liquid crystal display panel LCP, which will be described later, and a backlight EL panel ELP for the panel LCP are disposed substantially coaxially in front and rear.
Both of these panels are mounted on the mounting substrate 16 and constitute a display unit as a whole. And
The mounting substrate 16 is a cover member 17 that covers the rear of the housing 14.
And the housing 14, and are fixedly fastened with screws or the like.

As shown in FIG. 2, the liquid crystal panel LCP of the present example has a liquid crystal 1
A TN mode structure is used in which a liquid crystal cell is constructed by sandwiching the transparent substrate 19 and 20 from both front and rear sides of the substrate 8 and polarizing plates 21 and 22 are attached to both surfaces thereof.

Although not shown in detail, transparent electrodes are respectively arranged in a matrix on the inner surfaces of the transparent substrates 19 and 20, and the substrates are printed on the mounting substrate 16 through the conductive connectors 23 as shown in FIG. Connected to wiring. The mounting substrate 16 is connected to a control device (not shown) constituted by a microcomputer, whereby the liquid crystal panel LCP operates according to a command from the control device (not shown).
A predetermined number (a number from 0 to 9) can be displayed by the dot matrix method.

On the other hand, regarding the specific structure of the EL panel FLP,
As shown in the figure, three EL panel components EL1 to EL3 are arranged side by side so as to correspond to the respective numeric display areas LCP1 to LCP3 displayed on the liquid crystal display panel LCP. As shown in FIG. 3, each of the EL panel components EL1 to EL3 has a structure in which an insulating film 25 is laminated on the back surface of a phosphor 24 and sandwiched between transparent electrodes 26 and 27 from both sides thereof. Both of these electrodes 26 and 27 are connected to a driving power supply (not shown), and emit EL light when a voltage is applied. In this example,
As the EL panel components EL1 to EL3, those having different emission colors are used, and in the case of FIG. 5, red, blue, and yellow are arranged in order from the left.

The size of the EL panel ELP is set so as to illuminate almost the entire surface of the liquid crystal panel LCP.

The display device of the present example is configured as described above. Therefore, since a backlight using the EL panel ELP as an illumination source is realized for the liquid crystal panel LCP, an appropriate display contrast is obtained on the screen of the display device 9.
As a result, the symbols are displayed sharply, giving the display dynamics, and adding more fun to the game.

In addition, in the case of the present example, each number displayed on the liquid crystal display panel LCP is subjected to background irradiation in a different color, so that the display can be given an interestingness.

In addition, since a backlight is not a point light source such as a light bulb or a linear light source such as a fluorescent lamp, but has a structure in which a surface light source such as an EL panel is directly used, there is no need to replace the surface light source. In addition, by using a surface light source, the thickness of the display device can be reduced, and the luminance unevenness can be reduced. In the case of this example, since the EL panel ELP has the same size as the liquid crystal panel LCP, it is easy to make the luminance uniform.

Further, since both panels are assembled on the mounting substrate 16 to form a unit, it is convenient for handling or assembling. In addition, the EL panel ELP has the advantage that it does not break easily as in the case of a fluorescent lamp, and does not require much attention when assembling.

In this example, the three colors shown in the table are used.
A monochrome display may be used by using an EL panel. Further, if a light diffusion plate is interposed between the EL panel ELP and the liquid crystal panel LCP, the size of the EL panel ELP can be reduced. Further, the display on the liquid crystal display panel LCP is not limited to a number, but may be a character or the like. For example, a message such as "big hit, congratulations !!" Furthermore, the display method of the liquid crystal panel LPC is not limited to the dot matrix method, but may be a segment method.

FIG. 6 shows a second embodiment of the present invention.
In the embodiment, the display area of the EL pannel ELP is horizontally divided into three, and the numeral display areas LCP1 to LCP of the liquid crystal display panel LCP are provided at the center.
Arrange the number irradiation part EL4 corresponding to 3, blinking part EL above and below
5,6 are arranged. In the case of this embodiment, the numeral illuminating section EL4 is always lit, and the blinking sections EL5, EL6 are always in the unlit state, but are alternately lit when in the "hit state". In this case, the blinking part EL5,6
May be set to the same color or different colors. Also, it may be made to blink synchronously.

FIG. 7 shows a third embodiment of the present invention.
In the embodiment, the EL panel ELP is divided into a number of horizontal areas T1 to _TN , and is set so that the entire area is always in a lighting state. The lighting cycle is set so that the lighting state shifts in order.

However, the present invention is not limited to the one divided into horizontal regions as in this example, and may be one divided into vertical regions.

In any of the second and third embodiments, the interestingness of the change of the background in the "hit state" can increase the fun of the game.

FIG. 8 shows a fourth embodiment of the present invention.
In this embodiment, the EL panel ELP is provided with a hit state display section EL7 in a segment system. In this example, the entire EL panel ELP is always lit, but when the "hit state" is reached, the background is turned off and the hit state display section
Only the EL7 is turned on, so that the character "big hit" as shown in FIG. 8 is set to be displayed by a so-called negative display. In this case, the liquid crystal display panel
The LCP is in a non-display state, and the above characters are transparently displayed through the panel LCP.

It should be noted that, contrary to this example, a so-called positive display method in which the background is turned on and only the hit state display section EL7 is turned off may be used.

(Effects of the Invention) The effects of the present invention are as follows. In the present invention. Since the EL panel is divided into a plurality of regions and these are selectively blinked and displayed, the background of the display surface can be dynamically changed, thereby increasing interest.
