Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pachinko machine equipped with a liquid crystal display device for displaying game content on a game board surface.

Conventionally, a pachinko machine has been developed in which a display device using an 0IILT (cathode ray tube) is provided on the game board surface, and the game is played while displaying the game content on the CRT. However, this CRT display device has drawbacks such as being too large compared to the effective double-sided display device and requiring a high voltage for operation, so there are many problems in putting it into practical use when installed on the game board surface of a pachinko machine.

An object of the present invention is to provide a pachinko machine in which a liquid crystal display device is installed on the game board surface, thereby eliminating the drawbacks of the above-mentioned CRT display device.

Furthermore, as is well known, liquid crystals do not emit light when a voltage is applied to them, but instead change the transmittance or reflectance of light. Therefore, in dark environments such as the game board of a pachinko machine, external illumination light is inevitable. is necessary. For example, if there is only one light source serving as illumination light, and if it is cut out due to some kind of obstruction, the liquid crystal display (tracks) will become completely invisible, which will interfere with the game.

Therefore, another object of the present invention is to provide a plurality of light sources for projecting light onto the liquid crystal display surface, thereby solving the above-mentioned drawbacks due to light source failure.

In Figure 1, which explains the present invention in detail with regard to the illustrated embodiment, l is the main body of the pachinko machine, and the front side of the game board 2 has a large number of obstacle nails, a plurality of winning holes 3, and an out ball hole 4. At the same time, a prize winning ball device 5 and a liquid crystal display device 6 are integrally provided in a substantially central portion of the game board 2 and a liquid crystal display device 6 in its real portion.

Further, on the front side of the pachinko machine main body 1, a ball supply tray 7, a lower spare tray 8, and a firing handle 9 for firing balls are arranged.

As shown in Figures 1 and 3, the liquid crystal display device 6 has a polarizing filter 11 superimposed on the front surface of a glass substrate serving as a liquid crystal display surface 10, and a transparent polarizing filter 11 with electrodes is placed on the rear surface via a diffuser plate 2. It is constructed by overlapping glass substrates 13. This liquid crystal display device M6 is connected to the game control circuit of the computer, and displays the game image stored in its display memory on the liquid crystal display surface 10. In this example,
The display memory displays images of the baseball game on the liquid crystal display screen 10.

Incidentally, a transparent film 14 on which a ground is drawn according to the contents of the goo 4 is pasted on the front surface of the glass substrate 13. 15
and 16 are glass plates for protection.

The liquid crystal display device &6 is arranged to correspond to the central opening of the winning device 5 so that the player can see through it from the front, and the liquid crystal display device &6 is placed inside the box 17 fixed to the back side of the game board 2.
Tilt backward at an angle of ~20 degrees and ff! be done. In this way, by tilting the liquid crystal display device 6 after a predetermined angle, the liquid crystal display screen I
The game image displayed on O can be seen most clearly.

Further, at the rear end of the box 17 facing the liquid crystal display device 6, a plurality of lamps (for example, four in the embodiment) serving as light sources are provided. The light gamma source serves as external light to make the images displayed on the liquid crystal display surface 10 of the liquid crystal display device 6 easily visible to players, and sockets are formed in the four corners of the wiring board 19. It is detachably attached to each socket from the rear of the box 17. Light source box 17
[Liquid crystal display surface facing the inside of the screen without light leaking to the surroundings]
Uniformly illuminate the entire surface of 0. In this way, by providing a plurality of light sources, even if one of the light sources goes out, the remaining light sources 18 can be used to illuminate the liquid crystal display surface 10, which has the advantage of not interfering with the game. be.

When the light source burns out, it can be easily removed from the rear of the box 17 and replaced.

In the case of this embodiment, when a ball hits the winning hole 3, a plurality of display lamps arranged in a horizontal row at the bottom of the winning child device 5 move in sequence while lighting up in response to the detection signal. In this state, the player operates the operation switch 4 provided on the front side of the pachinko machine main body 1 to control the display lamp 21 to stop.

Then, a signal based on the job type information 23 (for example, in the illustration, the words OUT, HIT, and TWO BASES) shown at the stop position of the display lamp 21 is sent to the game control circuit, and the nrn stored in the display memory is sent to the game control circuit. For example, when the display lamp 21 stops at a position where two bases are displayed, an image of the player is displayed on the two-layer base of the liquid crystal display surface 10. Then, when the display lamp 21 stops at the position where two bases is displayed again by the next operation of the operation switch n, the statue of the player Il on the second layer base moves t above the home base and points are awarded.
At the same time, another player image is displayed on the two-layer base.

Then, the solenoid is pivoted in accordance with the score, and the opening/closing piece 5.25 of the winning device 5 is opened for a certain period of time in a state in which it is easy for the ball to win. In this way, the image of the game content stored in the display memory of the game control circuit is displayed on the liquid crystal display screen 10 by the winning signal to the winning opening 8, and the pachinko game based on the game content can be enjoyed. .

As described above, according to the present invention, a liquid crystal display device is provided on the game board surface, and the units of the game content are displayed on the liquid crystal display surface, so that the interest of playing pachinko can be significantly increased. The liquid crystal display device requires less installation space than the conventional ORT display device, and can also be assembled integrally with the winning device, allowing effective use of the game board surface. Furthermore, since it operates with very little electric power, it is economical and highly safe.

Furthermore, by providing multiple light sources to illuminate the liquid crystal display surface, even if one of the light sources goes out, the liquid crystal display surface will be illuminated by the remaining light sources, which has the advantage of preventing situations that would interfere with play. be.
