PROBLEM TO BE SOLVED: To provide a Pachinko game machine which facilitates the visual recognition of obstacle nails and how game balls flow down by achieving an ideal lighting even when a chance is limited to be given for emission performances using a decoration lamp or the like installed in a playing area. SOLUTION: The side facing the insertion opening part of a light projection port 85 is so formed as to have an inwardly inclined surface 87 expanding toward a groove from the internal surface of a housing part 81 while two sides adjacent to the side facing the insertion opening part are so formed as to have an outwardly inclined surface 86 expanding onto the internal surface of the housing part 81 from the groove. The light emitted from the light emitting surface of a light emitting diode 108 travels toward the surface of the game board with the inwardly inclined surface 87, thereby preventing the light from directly entering the eyes of players, while travelling to the internal space of the unit frame with the outwardly inclined surface 86, thereby enabling the bright lighting of the internal space of the unit frame.
