BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a symbol-variable display device for a symbol-combination type gaming machine, and more particularly, to a symbol of a visible display portion opened on the front side of a gaming machine for developing a symbol-combination game. The present invention relates to a symbol variable display device including a stop line for displaying symbols on a stop line and illuminating a symbol facing the visible display portion from behind.

[0002]

2. Description of the Related Art In a pachinko machine, a slot machine, and the like that are provided as a symbol combination game machine, a symbol combination game is developed based on fluctuation control conditions including start and stop each time that occur during a game. For example, as a means capable of displaying the winning combination conditions which are the right relating to the special game state, for example, a "drum type" or a "belt type"
The design variable display device referred to as "design" is employed. Among these, for example, the symbol variable display device of the symbol drum type,
Although there are differences in size and fluctuation control conditions depending on the target gaming machine, the form and configuration are basically the same, and numerals and figures are attached to the outer peripheral surface of a flat pulley type drum rotating body made of synthetic resin. A symbol drum on which symbols such as marks are formed and arranged, a rotation driving means such as a stepping motor for rotating and stopping the symbol drum, a positioning detecting means for each symbol to be stopped and displayed, and an illumination means for illuminating and displaying each symbol A plurality of symbol display units (in general, left row, middle row, (3 units in the right row) are housed and set side by side.

In such a symbol variable display device, the symbol drums in each row are started to fluctuate in the set order and stopped based on the fluctuation control mode relating to each symbol combination game, and a symbol stop line (winning line). Based on the symbol detection information of the individual detecting means for the symbols in each row stopped and displayed above, a comparison detection with a preset combination symbol (also called a hit symbol) is performed, and "hit" or "missing" is determined. Controlled.
In addition, the lighting means is a case where a predetermined symbol combination condition may be satisfied by each row symbol stopped and displayed on the symbol stop line in the visible display portion (symbol perspective window) of the game board (a so-called “reach” state). ) Or in the case of actual establishment (so-called "big hit"), for the purpose of effectively lighting this for the player, for example, blinking display at the time of "reach",
At the time of "big hit", it is designed so that the display effect for each symbol combination can be enhanced as a continuous lighting display.

[0004]

The illuminating means of each symbol display unit in the symbol variable display device, as described above, has a function of notifying the illumination so as to emphasize the symbol when a "reach" or "big hit" occurs. And at the same time, a function of uniformly illuminating the entire symbol visible display portion to enhance the interest in the game and give the player a high impression and a strong impression. However, the conventional illumination means required an illumination lamp for illuminating the symbol stopped at the symbol stop line and an illumination lamp (mainly an LED lamp) for illuminating the entire visible display portion. There were restrictions on installing these multiple lamps in the limited space inside. For this reason, it is often impossible to install each lamp at an appropriate position and in an appropriate direction, and in such a case, a high lighting effect cannot be obtained, so that a high impression and a strong impression cannot be given to the player. There was an inconvenience. In addition, it has been pointed out that since a large number of lamps are used, the manufacturing cost increases as the number of parts increases.

On the other hand, in the symbol drum, even if the rim portion on which the symbols are arranged can transmit the irradiation light of the lamp in the illuminating means, the rim portion itself merely transmits the irradiation light and does not emit the irradiation light. Does not have the function of diffusing Therefore, the color and color tone of the pattern irradiated from the inside are poor and the lighting effect is low. Also, since a large number of lamps are installed inside the rotating drum, it is not possible to provide a reflector for reflecting the irradiation light radiated toward the rear side of the lamp toward the rear side of the rim of the design drum at this installation site, and the rear side is not provided. There is also a problem that the irradiation light cannot be used to illuminate the visible display portion.

Further, the stepping motor, the detecting means and the illuminating means are not directly electrically connected to the driving base, but are formed separately from the driving base and dedicated relays fixed to the driving base. They are electrically connected via a base. For this reason, the number of parts is increased and the number of assembling work steps is also increased, so that an increase in manufacturing cost due to this is not negligible.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems inherent in the prior art, and has been proposed in order to solve the problem suitably, and uses a lamp having directivity to irradiation light. By devising the installation form of the lamp on the premise, it is possible to improve the lighting effect by enabling the same lamp to cope with the illumination of the entire visible display portion and the irradiation of the symbol stopped on the symbol stop line. It is another object of the present invention to provide a symbol-variable display device for a symbol-combination-type gaming machine, which enables cost reduction by reducing the number of parts and the number of assembly steps.

[0008]

As described above, in the symbol variable display device for a symbol-combination type gaming machine according to the present invention, the irradiation lamp for irradiating concentrated light to the front of the tip and irradiating diffused light to the side is provided on the base. Along with the arrangement surface, and arranged in an inclined state with the tip directed to the design stop line,
A reflector was provided on the opposite side of the illumination lamp from the portion facing the visible display portion of the symbol display. Thus, when the emission lamp is controlled to emit light, the concentrated light emitted toward the front of the tip is emitted toward the symbol stopped at the symbol stop line, so that the symbol can clearly appear in the symbol visible portion. At the same time, the diffused light radiated to the side can uniformly illuminate the entire surface of the design visible portion, so that there is an advantage that a high illumination effect can be obtained and a high impression and a strong impression can be given to the player. In addition, since a single irradiation lamp can be used for both illumination of the design and illumination of the entire visible portion of the design, there is also an advantage that the cost can be reduced by reducing the number of parts. Further, since the pattern display body is formed from a material having a light transmitting property and a convex portion is provided on the back side so that light can be diffused, the entire surface of the visible display portion can be illuminated more brightly. It can be expected that the lighting effect will be improved.

Further, in the symbol variable display device according to the present invention,
The rotation drive means and the detection means constituting each symbol display unit are directly connected to the corresponding drive circuits and detection circuits formed on the base. Therefore, there is an advantage that a dedicated relay base conventionally used is not required, and the cost can be further reduced by reducing the number of parts.
