【Example】
Next, an embodiment of the present invention will be described with reference to the drawings.
In a symbol display device mounted on a game board 1 of a pachinko machine, a transparent window plate in which a peripheral part is held in an opening 1a of the game board 1 by a window frame 2 fixed to an opening edge of the opening 1a. 3 is installed vertically.
[0012]
In the lower part of the frame 4 connected to the window frame 2, there is installed a symbol display body 6 which can display one or more sets of symbol groups in a variable manner and the control device 5 controls the variation display mode of the symbol groups. In this example, a liquid crystal display is used as the symbol display body 6.
[0013]
Below the symbol display body 6, a light source 7 for irradiating auxiliary light to the symbol original image displayed by the symbol display body 6 from below is installed.
[0014]
Above the symbol display 6 and behind the window plate 3, a mirror 8 that reflects the light beam 10 of the symbol original image projected upward by the light source 7 is tilted (in FIG. 1, about 45 °). This is exemplified by the inclined position .
[0015]
A shaft insertion member 12 supported so as to be swingable by a swing shaft 11 is coupled to the lower end of the mirror 8, and a driven member 13 having a horizontally long guide hole 13 a is coupled to the upper end of the mirror 8.
[0016]
A transmission member 14 having an eccentric pin 14 a inserted into the guide hole 13 a of the driven member 13 is fixed to the output shaft of the mirror drive motor 17 installed on the side of the driven member 13.
[0017]
When the output shaft of the mirror drive motor 17 is continuously rotated, the driven member 13 is repeatedly reciprocated by the eccentric rotation of the eccentric pin 14a of the transmission member 14, and the mirror 8 is repeatedly reciprocated and reflected by the mirror 8 to the front. The light beam 10 of the pattern original image projected on the screen repeatedly moves back and forth in the vertical direction.
[0018]
When the output shaft of the mirror drive motor 17 rotates in an inching manner, the tilt angle of the mirror 8 increases or decreases, and the reflection angle at which the mirror 8 reflects the luminous flux 10 of the pattern original image is adjusted.
[0019]
Between the mirror 8 and the window plate 3, there is a convex lens 18 that transmits the light beam 10 of the pattern original image reflected by the mirror 8 and projected forward, and projects the magnified and formed pattern image to the front position. is set up.
[0020]
In front of the game board 1, a pair of front and rear transparent plates (glass plates) 15 that are fitted in the frame of the transparent board support frame 19 and cover the game board 1 are vertically installed. On the rear surface of the transparent plate 15 on the rear side, a screen portion 16 is formed in the shape of a frosted glass on which a symbol image formed by projecting the luminous flux 10 of the symbol original image that is transmitted forward through the convex lens 18 and the window plate 3 is projected. Then, a symbol image obtained by enlarging the symbol original image of the symbol display body 6 by the convex lens 18 is displayed on the screen portion 16.
[0021]
The screen portion 16 is opaque or translucent, and is formed by sticking a film piece in which a part of the transparent plate 15 is ground glass to the transparent plate 15.
[0022]
However, a ground glass-like screen portion 16 may be formed by roughening a part of the transparent plate 15.
[0023]
The symbol display body 6 variably displays, for example, four sets of symbols, and when the game balls win, for example, at the start opening of the game board surface, the variation display of the symbol groups of each group is started simultaneously.
[0024]
When the symbol display body 6 starts the variable display of each symbol group, four symbol images in which the symbol original images of each symbol group in the variable display are enlarged are projected on the screen unit 16 and displayed. A set of symbol image groups is variably displayed on the screen unit 16.
[0025]
When a predetermined time elapses after the symbol display body 6 starts to display the variation of the four sets of symbols, the symbol display body 6 sequentially stops the variation display of the symbol groups of each group, and when the variation display of the symbol groups of each group is stopped. Four specific symbol images obtained by enlarging the respective symbol original images of the four specific symbols specified are displayed on the screen unit 16 in a horizontal row.
[0026]
When it is determined that the combination of the four specific symbol images projected on the screen unit 16 is a winning combination, the big prize opening on the game board surface is opened for 30 seconds, for example, and the combination of the four specific symbol images is determined. If it is determined that the combination is out of place, the special winning opening is not opened.
[0027]
When the winning ball that has won the big winning opening passes through the specific area, the big winning opening is again opened for 30 seconds.
[0028]
Subsequently, the operation and effect of the embodiment having the above-described configuration will be described.
In this example, the transparent plate 15 erected in front of the game board 1 is formed with a screen portion 16 for projecting a symbol image obtained by enlarging the symbol original image displayed by the symbol display body 6. A part of the transparent plate 15 is stuck to the plate 15 to form a ground glass.
[0029]
For this reason, the symbol image can be projected on the screen unit 16 in a state where the symbol image floats up from the game board surface and floats in the air, and the display mode of the symbol can be specified to create interest in the display symbol. .
[0030]
Further, the transparent board 15 covering the game board surface can be effectively utilized to reveal a large symbol image, the space occupied by the conventional symbol image display unit can be substantially eliminated, and the transparent plate 15 The screen portion 16 can be easily set at a predetermined position simply by assembling the transparent plate support frame 19.
[0031]
Further, since the screen portion 16 is formed by sticking a film piece to the transparent plate 15, the screen portion 16 can be easily installed at an arbitrary position of the transparent plate 15, and the size of the screen portion 16 The shape and color can be arbitrarily selected.
