DESCRIPTION:
BRIEF SUMMARY
FIELD OF TECHNOLOGY
This invention relates to a slot machine in which a plurality of symbols are to be changed by inserting tokens into a slot and activating a game start switch and are then stopped at preset times.
BACKGROUND TECHNOLOGY
The conventional slot machine of this type is exemplified by Japanese Utility Model Laid-Open Publication No. SHO 54-130590. In this conventional slot machine, tokens or coins are individually inserted into a slot to rotate three drums displaying symbols, and stop switches are then depressed to stop the drums one after another. Depending on the combination of symbols, a predetermined number of tokens are dispensed as a prize.
In another conventional slot machine, a cathode ray tube instead of the rotary drums is situated on a front side of the slot machine and displays symbols in three rows and three columns, i.e., nine symbols in total.
In every amusement parlor, in order to attract many customers to increase profits, it has long been desirable to minimize the space to be occupied by a single game machine so that as many game machines as possible can be installed in the parlor. However, in the former conventional slot machine, since the size of the individual drum is restricted by the size and number of the symbols to be displayed on the drum, reduction of the depth has limits. In the latter slot machine, because of an electron gun used in the cathode ray tube, reduction of the depth also has limits. Consequently in an amusement parlor where both the conventional slot machines and pachinko machines are to be installed, since the depth of the slot machine cannot be reduced down to that of the pachinko machine, all islands of these game machines must be divided into slot machine islands and pachinko machine islands so that planning, designing and construction of the amusement parlor is complex, requiring much time and cost.
Further in the latter slot machine, since symbols are displayed in the form of a single plane on the screen of the cathode ray tube, it lacks the visual appeal and fun, compared to using drums.
DISCLOSURE OF THE INVENTION
With the foregoing problems in mind, it is therefore an object of this invention to provide a slot machine which requires a reduced installation space to increase profits for the amusement parlor and because of which planning, designing and construction of the amusement parlor can be simplified to save time and cost, without impairing visual appeal and fun.
According to a first aspect of this invention, the above object can be accomplished by a slot machine which is to be started by inserting tokens into a slot and by activating a game start switch to turn and change a plurality of symbols and then stop the symbols in timed relation with activations of respective stop switches, the slot machine comprising: a plurality of liquid crystal displays situated on a front side of the slot machine; and display controlling means for controlling the liquid crystal displays to display a combination of the symbols.
Each of the liquid crystal displays may have a front convex surface and may include a plurality of liquid crystal display plates connected to one .another at an angle.
The slot machine may further comprise result discriminating means for discriminating whether or not the combination of the stopped symbols coincides with any of predetermined prize winning combinations, the display controlling means being operable to control the liquid crystal displays to display a predetermined result when the result discriminating means discriminates that the combination of the stopped symbols coincides with one of the predetermined prize winning combinations.
The liquid crystal displays may be capable of displaying the predetermined result by flashing the individual symbols of the prize winning combination as discriminated by the result discriminating means or by flashing the background of the last-named individual symbols.
The liquid crystal display may be capable of displaying the predetermined result by flashing frames respectively encircling t
