So far as the concrete mechanism of the EL panel ELP is concerned, an insulating film 25 laminated on the rear side surface of a fluorescent lamp 24 is to be placed between transparent electrodes (segment electrodes) 26, 27, from both the sides of the film 25 and the lamp 24.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a display device for a pachinko machine.

(Prior art) Conventionally, when a pachinko machine enters a specific winning slot, the symbols (numbers, letters, patterns, etc.) on the display device change, and if a specific combination has been obtained when the machine stops, it will be a jackpot or retail. There is a so-called fever type, which is a type of heat exchanger.

The display devices used in this type have a display panel built into them, and the above-mentioned symbols are variably displayed on the screen.

It is especially desirable for such a display panel to have low power consumption and be structurally compact. Liquid crystal display panels are excellent in these respects and are widely used in general display panels.

However, since the product display panel itself is non-luminous, there is a problem in that the screen is dark and lacks contrast, making it difficult to see the display. Therefore, if you apply this to a pachinko machine as is, the displayed patterns will lack sharpness,
The expressive power of the design will be lost. Since the display device is an important element for making the game more interesting, some kind of countermeasure is required. Therefore, as a countermeasure to this problem, it is conceivable to set a backlight light source such as a fluorescent lamp on the back side of the product display panel.

(Problems to be Solved by the Invention) A specific example of this is a configuration in which a fluorescent lamp is set as a backlight light source and this is arranged on the back side of a product display panel. However, in these (14), the fluorescent lamp itself is a component that requires space for installation in the depth direction, so the entire display device becomes quite thick.This makes handling the display device alone, and also makes it difficult to handle pachinko. When installed in a machine, the amount of rearward protrusion becomes large, and there is a risk of it being hit during transport.

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

Furthermore, the colors emitted by fluorescent lamps do not provide a vivid color display, so they are by no means sufficient to make the displayed symbols stand out in color, and are not satisfactory in terms of increasing the fun of the game.

The present invention has been made in view of the above problems,
It is an object of the present invention to provide a display device having a compact configuration and rich in expressive power of patterns.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a display device mounted on the game board of a pachinko machine, which includes a transmissive liquid crystal display panel and a display device mounted on the back side of the liquid crystal display panel. The structure incorporates an electroluminescent panel (hereinafter referred to as an EL panel) that also serves as a backlight and displays a predetermined display through a similar crystal display panel.

(Function) According to the above configuration, the display on the EL panel is transmitted through the liquid crystal display panel, and the contrast of the display on the liquid crystal display panel is not enhanced by the back illumination light from the EL panel, which is a surface emitting source. It becomes something.

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

First, a pachinko machine equipped with a display device will be explained with reference to FIG. Various winning holes are arranged on the game board 1, of which 2 to 5 are normal winning holes, but 6 to 8 are normal winning holes.
is a starting port for causing the display device 9, which will be described below, to start changing the symbols. A symbol is variably displayed on the display device 9 (a 3-digit number variably displayed by the EL panel ELP, which will be described later) when a prize is won in any of the starting ports 6 to 8.
If a specific combination is obtained when the game stops after a certain period of time has passed, a "winning state" occurs and the V winning opening 10 located below the display device 9 is set to be open for a certain period of time. It becomes.

The display device 9 placed approximately in the center of the game board 1 has a case body 12 as shown in FIG.
The housing 14 of the case body 12 is inserted into the mounting hole 13 opened in the game board 1, and the whole is installed. The housing 14 is formed into a rectangular tube shape that opens in both the front and rear directions, and a transparent cover plate 15 is fitted into the front opening from the inside.

Further, inside the housing 14, a liquid crystal display panel LCP and an EL panel ELP, which will be described later, are arranged approximately coaxially in the front and rear. Both of these panels are mounted on the mounting board 16, and constitute a display unit as a whole. The mounting board 16 is sandwiched between the housing 14 and a cover member 17 that covers the rear of the housing 14, and is secured by screws or the like.

In addition, 11-11 are windmills.

The liquid crystal display panel LCP of this example is as shown in FIG.
One transparent substrate for the liquid crystal 18 on both front and rear sides.

20 to form a liquid crystal cell, and polarizing plates 21 and 22 are attached to both sides of the cell to form a TN mode structure. In addition, the liquid crystal display panel LCP used is one that can obtain sufficient transmitted light when no voltage is applied to the liquid crystal, and in this state, the display on the EL panel ELP, which will be described later, can be transmitted and displayed through the liquid crystal display panel LCP. .

Although not shown in detail, transparent electrodes are arranged in a matrix on the inner surfaces of the transparent substrates 19 and 20, respectively, and
As shown in FIG. 1, the board is connected to printed wiring on the mounting board 16 via a conductive connector 23. This mounting board 16 is connected to a control device 28 (see FIG. 5, which will be described later) constituted by a microcomputer, thereby controlling the liquid crystal display panel L.
The CP is capable of variably displaying predetermined characters or appropriate patterns using a dot matrix method in accordance with commands from the control device 28.

The specific display format of the liquid crystal display panel LCP in this example is that it is always in a non-display state and that the E
A three-digit number variably displayed on the L panel ELP is transparently displayed. When the above-mentioned "winning state" occurs, a message such as "Congratulations on the jackpot!" is displayed on the liquid crystal display panel LCP while scrolling in the horizontal direction.

On the other hand, regarding the specific structure of the EL panel ELP, as shown in FIG. In other words, the EL panel ELP uses the 7-segment method to
Digits can be displayed side by side. Further, these electrodes 26 and 27 are connected to printed wiring on the mounting board 16, and are further connected to the aforementioned control device 28 to control lighting.

However, in this example, the settings are such that a positive display is always performed, leaving the 3-digit number part and lighting up the other part (background) as one segment. At certain times, the lighting state is set to be switched to a non-display state, that is, a full lighting state in which all segments are lit. However, in areas other than the 3-digit number display area, EL light is emitted (in this example, monochromatic yellow-orange light is used, but it is also possible to change the color of light emitted only in the number segment. ), so you can always enjoy a bright color digital display, and in the event of a hit, this serves as a backlight for the display on the liquid crystal display panel ECP.

As shown in FIG. 5, the control device 28 includes a CPU 29 that performs digital calculation processing, a ROM 30 that stores programs and fixed data, and an RA that stores the results of calculation processing.
It consists of a microcomputer with M31 etc. as its main part. Then, according to the program stored in the ROM 30, the signal from the winning detection switch 33 via the waveform shaping circuit 32 is inputted into the CPU 29 as human power information, and the lighting control of both the EL and liquid crystal display panels or the winning opening 10 is performed. Controls the operation of the opening/closing solenoid 34, etc.

The display device of this example is configured as described above.

Therefore, the display device 9 always displays the display (positive display) on the EL panel ELP or the transparent display through the LA panel ECP. Then, when there is a winning ball in the starting ports 6 to 8, the display on the EL panel ELP starts changing according to a command from the control device 28. As a result, if the combination of "hit state" is obtained when the display stops, the entire surface of the EL panel ELP lights up, and while receiving back illumination from here, the above-mentioned image appears on the liquid crystal display panel LCP. A message is displayed.

Listing the effects of this example, in the display device, the numbers on the EL panel ELP are displayed in a bright luminescent color (yellow-orange in this example).
Since the game can be displayed in color against the background, it becomes a dynamic display and increases the interest of the players. In addition, since the "winning status" is displayed on the liquid crystal display panel LCP using a dot matrix display, it is possible to set a variety of displays such as messages such as the one in this example, as well as various designs or combinations of these. It's easy.

Moreover, when these displays are performed, the EL panel EL
Since it is backlit by P, similar to the above, a bright color display and appropriate contrast are obtained, making the display extremely easy to see. In addition, EL
Two types of panels, a panel and a liquid crystal display panel, have different graphic expression capabilities, and one is a segment display and the other is a matrix display, so by switching or combining these, it is possible to expand the range of design expression methods. This brings about the effect that players can also enjoy a variety of displays.

Note that the IfI product display panel LCP may be used as a segment display, and in this case, although the expressive power is slightly inferior to the matrix display, there is an advantage that display control is simplified. Further, the EL panel ELP may be displayed using a dot matrix method. In this case, although display control becomes complicated, the power of expression increases.

In addition, by using an EL panel, the display and backlight functions can be discontinued, so the number of parts is reduced, and it is possible to achieve a simple t + Ili + iM, and to make the entire display device thinner. .

Furthermore, by using a surface light emitter called an EL panel, uneven brightness can be reduced. In this example, since the EL panel ELP is approximately the same size as the liquid crystal display panel LCP, it is easy to make the brightness uniform.

Furthermore, since both panels are assembled onto the mounting board 16 to form a unit, it is convenient for handling and assembly. Furthermore, the EL panel ELP does not break easily unlike fluorescent lamps, and has the advantage that it does not require much care during assembly.

Note that by interposing a light diffusion plate between the EL panel ELP and the liquid crystal display panel LCP, the EL panel ELP can be made smaller.

Further, in this example, the liquid crystal display panel LCP is always set to no display, but an appropriate pattern may be displayed in an area that does not interfere with the transmissive display area of the EL panel ELP.

Contrary to this example, the EL panel ELP may have a negative display format, but a positive display is preferable for display that is viewed continuously for a long time. Further, when displaying the "winning state", for example, the EL panel ELP may alternately repeat a positive display and a negative display, or the EL panel ELP may blink to add further dynamism to the display.

Note that the EL panel ELP alone may be used instead of the conventional 7-segment LED without using the liquid crystal display panel LCP.

(Effect of the invention) The effects of the present invention are as follows.

By using an EL panel for transparent display, the vivid color light emission adds dynamism to the display, and since the display on the product panel is also illuminated by this vivid backlight, the color A distinctive display can be obtained, and the player's interest can be greatly increased. Furthermore, by using two types of displays, an EL panel and an M-product display panel, and by switching between them or displaying them in combination, it is possible to enjoy a variety of display of symbols.

Furthermore, since the EL panel is used both as a display and as a backlight, the display device's (lXt) construction becomes simple, and at the same time, the entire device can be made thinner.This makes it easier to handle the display device, and When incorporated into a pachinko machine, the amount of rearward protrusion can be reduced, and damage can be avoided.

Furthermore, since the EL panel is a surface emitting source, it can also contribute to achieving uniform brightness.
