<p><P>PROBLEM TO BE SOLVED: To provide a game machine, which prevents the illegal hitting of a jackpot to some extent by blocking radiowaves emitted toward a photosensor through a gap between a starting lever and a lever housing. <P>SOLUTION: This game machine comprises the lever housing 142 detachably attached to a box 102, the starting lever 11 supported by the lever housing 142 such that it is swingable, the photosensor 108, which is composed of a light emitting element and a light receiving element for emitting and receiving light, respectively, and generates an electric signal when the light receiving element receives light, a baffle 107, which interrupts light emitted from the light emitting element toward the light receiving element when the starting lever 11 is not operated and which is displaced by the turning of the starting lever 11 to let the light receiving element receive light emitted from the light emitting element toward the same when the starting lever 11 is operated, and an incident radiowave blocking means 104, which covers the gap between the starting lever 11 and the lever housing 142 from the inside of the box 102 to block radiowaves emitted toward the light receiving element. <P>COPYRIGHT: (C)2004,JPO</p> |
