Abstract: A mechanical slot machine is disclosed in which a band is arranged around a peripheral edge of a wheel capable of rotating together with a reel and coaxially with the rotational axis of the reel, for the purpose of detecting the positions of individual symbols formed on the reel. The band includes regions having mutually different attributes, and the boundary between the regions of the band shifts position across the width of the band as the boundary extends along the length of the band.

Abstract: A game machine includes a display which displays a plurality of identification images, each having a numeral image and a symbol image. The symbol image of the identification image is changed at a predetermined opportunity while maintaining a corresponding numeral image of the identification image when a predetermined progression is established among the numeral images of the identification images. Also, sequential numbers among the numeral images of the identification images are changed to another sequential numbers having a beginning number different from a beginning number of the sequential numbers at a predetermined opportunity when the sequential numbers are established among the numeral images of the identification images.

Abstract: A token discriminating device includes: a rolling member having two guide walls and a bottom for defining a rolling passage in which a token is rolled; and a smaller unacceptable token discriminating portion having: a cut-away portion formed in one of the two guide walls; a deflective wall provided in an upper portion of the cut-away portion to define a discriminating opening, a discriminating distance between the bottom and a lower end of the deflective wall being smaller than the diameter of an acceptable token, the deflective wall being bent outward of the rolling passage; a deflector provided on the other guide wall at a position facing the discriminating opening for deflecting a rolling token to the discriminating opening.
