<P>PROBLEM TO BE SOLVED: To provide a game machine which facilitates setting of a reference level of a quantity of light for detecting a passing state of game media and enables false detection of the passing state of the game media to be reduced. <P>SOLUTION: A pawl part 532a of an input gate member 530a includes a recessed part 532a1 on a surface facing an optical path through which light passes in an input sensor unit provided in a downstream side of a flowing direction. The recessed part 532a1 is formed in an entire part of a substantially central part with a prescribed distance spaced from an outer edge of the pawl part 532a and has a sectional form substantially in the shape of V. The formation of recessed part 532a1 reduces the possibility that light emitted by a light-emitting element is reflected on the surface of the pawl part 532a and the reflected light is received by a light-receiving element. Consequently, since unevenness in the quantity of light received by the light-receiving element is reduced, the reference level of the quantity of light for detecting the passing state of the game media is easily set and the false detection of the passing state of the game media is reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
