Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stereoscopic display game machine, and more particularly to a stereoscopic display game machine for stereoscopically displaying a game image using a lenticular lens.

[0002]

2. Description of the Related Art At present, for example, in a pachinko game machine, when a game ball is won in a predetermined winning opening, a number, a symbol, a pattern or the like is displayed on a drum or a display arranged almost in the center of the pachinko game board. Is variably displayed and "7,
A predetermined number of prize balls are played when the same number or the like, such as "7, 7", is stopped as a big hit. A CRT (Cathode Ray Tu
be) and liquid crystal display devices (LCD: Liquid Cristal Displa)
y) and the like are used, and the above-mentioned patterns are displayed by black and white binary display and color display, and game display other than that is performed to make the game content more interesting.

However, the image displayed on the display is a planar two-dimensional image, but it has been considered to make the display image three-dimensional in order to further enhance the display effect. Therefore, as a method of stereoscopically viewing an image, for example, holography is used, or a right-eye image and a left-eye image are alternately displayed on a display in a time-division manner, and glasses for the right eye such as glasses using a deflection plate The image and the image for the left eye are separated and taken in, or the lenticular lens with a sharp directivity is used to provide image information corresponding to the left and right eyes so that a stereoscopic image can be obtained with the naked eye. Etc.

[0004]

However, in such a conventional stereoscopic display game machine, for example, when a moving image is displayed by using holography, the display device becomes expensive and the deflector plate is used. In the time-sharing method, the device configuration is complicated and expensive, and it is necessary to use special glasses, etc. In addition, the images of the left eye and the right eye are switched at high speed alternately, so flicker on the screen is a concern. There is a problem that it ends up.

In this respect, when stereoscopic vision is performed using the lenticular lens, there is an advantage that a stereoscopic image can be obtained with the naked eye, the apparatus configuration is relatively simple, and the cost can be reduced. However, in stereoscopic vision using this lenticular lens, it is necessary to accurately align the images for the right eye and the left eye according to the convex lens positions of the lenticular lens. If the pitch is deviated, not only a stereoscopic image cannot be obtained, but also the original image cannot be viewed correctly.

Therefore, it is conceivable to perform accurate alignment during the manufacturing process of the display panel and directly attach the lenticular lens on the display panel in advance. However, when it is desired to display a normal two-dimensional image, the lenticular lens is displayed. There is a problem that the lens cannot be removed. That is, depending on the game machine, it is not always possible to display only the stereoscopic display, but the normal 2
It is desirable to be selectable so that the three-dimensional image can also be displayed.

Further, even if the lenticular lens is configured to be removable, a separate fixing member for accurately aligning and fixing the lenticular lens is required, resulting in high manufacturing cost and assembly cost. There is a problem.

Therefore, the present invention has been made in view of the above problems, and the lenticular lens and the image display section are accurately aligned with each other, and the lenticular lens can be attached and detached at a low cost. An object of the present invention is to provide a stereoscopic display game machine that can be realized.

[0009]

An image display unit that is provided in a game area where a predetermined game is played and displays a game image, a transparent plate made of a transparent member that covers the front surface of the game area, and the transparent plate corresponding to the front surface of the image display unit. The above-described object is achieved by including a lenticular lens integrally formed at a position and having a plurality of semi-cylindrical convex lenses arranged in the lateral direction.

In this case, for example, the invention according to claim 2 achieves the above-mentioned object by the fact that the lenticular lens disposed in front of the image display section is configured to be detachable.

Further, for example, in the invention according to claim 3, the display surface of the image display portion is formed so as to project to the front surface of the game area so as to be close to the rear surface of the transparent plate provided with the lenticular lens. By doing so, the above object is achieved.

Further, for example, in the invention as set forth in claim 4, the image display section is composed of a liquid crystal display panel, and an image display area for the right eye and a left eye are provided at positions corresponding to the respective convex lenses of the lenticular lens. The above object is achieved by forming a pair with the image display area.

[0013]

According to the first aspect of the invention, the image display section is provided in the game area, the front surface of the game area is covered with the transparent plate, and the transparent plate is placed at a position corresponding to the front surface of the image display section. Since the cylindrical lens is integrally formed, the planar image displayed on the image display unit can be displayed as a stereoscopic image, and the lenticular lens can be easily aligned, so that the manufacturing cost and the assembly cost can be reduced.

According to the second aspect of the invention, since the lenticular lens disposed on the front surface of the image display section is detachable, a normal two-dimensional image and a three-dimensional image can be selectively displayed.

According to the third aspect of the present invention, the image display section is arranged so as to project to the front of the game area so that the display surface of the image display section is close to the lenticular lens.
The display image and the lenticular lens are in close contact with each other, and an appropriate stereoscopic image is obtained.

According to the present invention, the image display section is composed of a liquid crystal display panel, and the right eye image display area and the left eye image display area are paired at positions corresponding to the respective convex lenses of the lenticular lens. Since the display image and the lenticular lens are arranged so that the display image and the lenticular lens can be easily aligned with each other, reliable and proper stereoscopic viewing can be performed.
