ABSTRACT:
Eight character symbols, all of equal pitch, and two blank symbols are arranged on a reel in a rotational direction thereof. As to each of the eight character symbols, one stop position is set so as to stop the center of the character symbol at a winning line. As to each of the two blank symbols, three stop positions are set. One of the three stop positions is selected on the basis of a random number and the blank symbol is stopped at the selected stop position. Accordingly, although the number of equally spaced symbols is ten, fourteen stop positions are obtained. The reel is rotated by a step motor. The stop position is determined according to the number of drive pulses supplied to the step motor.
