Abstract

A slot machine includes a plurality of rotary drums on the periphery of which plural frames of patterns are depicted. Detecting plates are connected to each rotary drum and the detecting plates are provided with pattern detecting elements whose number corresponds to the number of frames. Readers detect passage of the pattern detecting elements during drum rotation, and a control device counts the output of the readers and specifies the patterns positioned on a stop line based on the counted value after the drum stops. Each of the detecting plates provides for pattern confirmation which discriminates the pattern positioned on the stop line at least from the preceding and following frames of patterns when the drum is stopped, and the counted value is corrected in response to the pattern confirming device.
