Abstract

PURPOSE:To provide a dot matrix LED type display in which characters or patterns to be displayed can be clearly visually confirmed. CONSTITUTION:In front of a dot matrix LED 40, a cover body 50 formed by successively arranging a lot of convex lenses 51 is provided so that the respective convex lenses 51 correspond to respective LEDs 45 arranged in the shape of a matrix. Thus, since light emitted from two adjacent LEDs 45 is enlarged by the continuous convex lenses 51 and are radiated to the outside, block walls 42 disappear and the light emitted from two adjacent LEDs 45 is continuously visually confirmed so that the patterns or characters to be displayed can be clearly visually confirmed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for displaying characters, patterns, etc. by a large number of LEDs arranged in a matrix.

[0002]

2. Description of the Related Art In recent years, for example, in pachinko machines,
A display device that changes the design and can get a chance to win a large number of prize balls in a short time according to the change result, or a display device that displays the number of prize balls to the variable prize device or the number of times the variable prize device is repeatedly opened. It is becoming the mainstream that is provided with. Then, as a display of such a display device, a 7-segment LED, a dot matrix L
Display devices such as ED and LCD (liquid crystal display devices) are used, but the display devices using dot matrix LEDs among them are LEs partitioned by partition walls.
Since the letters and patterns are displayed by turning on D, the letters and patterns are naturally displayed by a collection of points (dots) clearly separated by the partition wall.

[0003]

Therefore, there is a drawback that it is very difficult to understand what character or design is displayed when the character or design is slightly complicated. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a display device of the dot matrix LED type in which displayed characters and patterns are clearly visible.

[0004]

In order to achieve the above object, in the present invention, a large number of convex lenses are individually provided in a display for displaying characters, patterns, etc. by a large number of LEDs arranged in a matrix. The cover body formed so as to correspond to the above LED is arranged in front of the cover body.

[0005]

Since the cover body in which a large number of convex lenses are formed so as to correspond to the individual LEDs is arranged in front of the cover body, the light emitted from the adjacent LEDs is magnified and emitted to the outside by the continuously formed convex lenses. Therefore, when viewed from the player's position, the partition wall disappears and the LED is lit
The light from is seen as a continuous line, and the displayed pattern or character can be clearly seen.

Further, each of the symbol display devices 15a to 15c is configured to variably display symbols of a predetermined type (for example, 15 types). The detailed structure of the symbol display devices 15a to 15c will be described later.

When the hit ball wins the variable operating port 21 provided below the center accessory 13, the symbol display devices 15a to 15c of the first symbol display device 14 start to change, and after a predetermined time elapses, left. The display is sequentially stopped from the symbol display 15a. Then, when the symbol combination at the time of stop becomes a predetermined symbol combination (in the present embodiment, the same symbol combination), the jackpot gaming state is set, and the front and rear slide plates 17 of the first variable winning device 16 are displayed. It is adapted to receive a hit ball that is retracted rearward for a certain period of time (for example, about 5.9 seconds) and falls in the game area 12. The hit ball (winning ball) received by the first variable winning device 16 is used to derive a display result of a second symbol display device 22 described later. Therefore, the first variation winning device 16 functions as a variation operating port of the second symbol display device 22. When the ball hits the variable working opening 21 while the first symbol display device 14 is changing and the first variable winning device 16 is being driven, the right to change the first symbol display device 14 to the first four is memorized.

Further, each of the symbol display devices 28a to 28c is adapted to variably display symbols of a predetermined type (for example, 12 types).

Therefore, the above-mentioned second variable winning device 25
When the hit ball is won, the variation of the symbol display devices 28a to 28c of the third symbol display device 27 is started, and after a predetermined time elapses, the symbol display devices 28a on the left side are sequentially stopped. And
When the combination of symbols at the time of stop becomes a predetermined combination of symbols (in the present embodiment, all combinations other than 0, 0, 0), it is a win, and the opening / closing member 31a of the third variable winning device 30 is selected. , 31b for a certain period of time (for example, about 5.9).
Seconds), or until a predetermined number of winning balls (for example, 6) are generated before the predetermined time has elapsed, the ball is opened to the left and right and the hitting ball falling in the game area 12 is received. ing. The hit ball (winning ball) received by the third variable winning device 30 is simply processed as a winning ball because there is no lower-level symbol display device. In addition, when the ball hits the second variable prize device 25 while the third symbol display device 27 is changing and the third variable prize device 30 is being driven, the right to change the third symbol display device 27 to the first four balls. Is stored, and the fact is displayed on the working memory display 29 provided below.

The above three symbol display devices 14,
Of 22 and 27, the first symbol display device 14 and the third symbol display device 27 are provided with a slight time interval when the display result is out of alignment, and the corresponding variable prize winning device 16 when hit. Immediately after the opening drive of 25 is completed, the operation moves to the next change operation based on the operation memory, but in the second symbol display device 22, regardless of whether the hit or miss occurs, the operation moves to the next operation change based on the operation memory. The time interval is set relatively long. Specifically, the third symbol display device 27
4 and the opening of the third variation winning device 30 based on
The time interval is set to be approximately the same as the time that is performed. Further, the probability that the second symbol display device 22 and the third symbol display device 27 display the hit is extremely high (1727/172).

Probability control of this first symbol display device 14,
For example, the value at the time of winning the ball hitting the variable working opening 21 is read from the random number counter which is updated every moment from 0 to 234 after the power is turned on, and the value is a predetermined value (for example,
When it is 0), it is determined to be a hit, and for example, one of the values extracted from the three symbol counters 1A to 1C for determining the symbol displayed on the symbol display devices 15a to 15c at that time. The symbols according to the value of the counter 1A are displayed on the symbol display devices 15a to 15c. Also, when the value of the random number counter is a value other than 0, it is determined to be out,
The symbols corresponding to the values of the symbol counters 1A to 1C extracted at that time are displayed on the symbol displays 15a to 15c.

In addition to the above-described structure, the game board 10 has ordinary winning openings 32a, 32b, 33a, 33b, 34a, 3

By the way, as the symbol display devices 15a to 15c of the first symbol display device 14, a display device constituting a main part of the present embodiment is used, and its detailed structure will be described with reference to FIGS. Will be described with reference to. FIG. 1 is a cross-sectional view of one symbol display device 15a, FIG. 2 is an explanatory diagram showing the dimensional relationship between the LEDs 45 arranged in a matrix and the convex lens 51, and FIG. 3 is one symbol display device. It is a perspective view of 15a. In the figure, the symbol display device 15a is composed of a dot matrix LED 40 having a large number of LEDs 45 arranged in a matrix, and a cover body 50 arranged in front of the dot matrix LED 40.

The dot-matrix LED 40 has a case 4 whose interior is partitioned and formed by a partition wall 42 in a grid pattern.
1. A diffusion seal 43 is attached to the front surface of 1, and a printed circuit board 44 on which a large number of LEDs 45 are provided in a matrix is inserted from the rear side thereof, and the rear surface of the printed circuit board 44 is sealed with a sealing resin 47. . The LEDs 45 provided on the printed circuit board 44 are formed so as to face the respective compartments in the case 41, and the LEs formed in a matrix form behind the printed circuit board 44.
A connecting pin 46 for sending a lighting signal to D45 is projected. In addition, the peripheral wall of each partition wall 42 is formed in a tapered shape so as to open toward the front.

On the other hand, the cover body 50 is formed of a transparent synthetic resin in a lid shape covering the front of the case 41, and a large number of convex lenses 51 having a short focal length are continuously formed on the front surface thereof. Then, the cover body 50 is attached to the case 4
When mounted on No. 1, each convex lens 51 is in contact with the individual lattice in the case 41, in other words, the individual LED 45. More specifically, FIG.
As shown in FIG. 4, when the length of the diagonal of each square lattice in the case 41 is L1, the convex lens 51 is
It is formed as a substantially spherical convex lens having a diameter of slightly longer dimension L2. For this reason, when the convex lens 51 is viewed from above, the side surface of a sphere having a diameter L2 is shaped like a square tube having a diagonal length of L1 cut off.

The symbol display device 15a configured as described above
The operation of the two adjacent LEDs 45 will be described.
The light emitted from the LED is magnified by the continuous convex lens 51 and is emitted to the outside. Therefore, the partition wall 42 disappears and the light emitted from the two adjacent LEDs 45 is visually recognized as continuous. Therefore, when viewed from the player's visual recognition position, the partition walls 42 are extinguished and the plurality of LEDs 45 that are lit and displayed are linearly viewed, and the displayed symbols or characters can be clearly viewed.

In the above embodiment, the cover body 50
As an example, the dot-matrix LED 40 is mounted on the case 41. However, it is not a method of directly mounting the dot-matrix LED 40 on the case 41. It may be one with a cover attached. Further, although the spherical convex lens 51 is described in the above embodiment,
According to the experiment, it is proved that substantially the same effect can be obtained when a hemispherical convex lens is formed on the front surface or the back surface of the cover body 50. Further, the display configured as in the present embodiment is not only a symbol display, but also a display for displaying the number of winnings, the number of times of opening, etc.
M × n matrix LED other than 5 matrix LED
However, it may be applied to fields other than gaming machines.

[0022]

As is apparent from the above description, in the present invention, a large number of convex lenses are provided for individual LEDs.
Since the cover body formed so as to correspond to is arranged in front of the cover body, the light emitted from the adjacent LEDs is magnified by the continuously formed convex lens and is emitted to the outside. The light from the LED, which is turned off when the partition wall disappears, looks like a continuous line, and the displayed pattern or character can be clearly recognized.
