PROBLEM TO BE SOLVED: To provide a game machine that enhances visibility of information display without disturbing the visibility of a decoration display part. SOLUTION: A game machine 100 that grants a benefit to a player according to the result of a lottery carried out for a game includes: a light source 200; and an optical function member 1000 where a light-transmissive base material is provided with a half-reflective area where the light emitted from the light source 200 enters the player's side from the side opposite to the player's side to transmit while the irradiation light from the player's side is reflected to the player's side. If the transmissive light emitted from the light source and transmitted through the optical function member is stronger than the light irradiated to the half-reflected area from the player's side and reflected by the half-reflected area, the half-reflected area becomes hard for the player to see or invisible due to the transmissive light. If the reflected light is stronger than the transmissive light, the half-reflected area becomes visible from the player. COPYRIGHT: (C)2011,JPO&INPIT
