ABSTRACT:
A slot machine has a plurality of reels, each having an annular series of various symbols on the periphery thereof and having, on a side thereof, a plurality of light shield plates different in shape from each other for distinguishing regions into which the reel is divided. Pulse signals for causing a pulse motor to rotate by an angle corresponding to each region are counted. A position of the reel either in rotation or stopped is determined based on the number of counted pulse signals and the region as distinguished by the detection of the shape of the associated light shield plate.
