PROBLEM TO BE SOLVED: To provide a Pachinko game machine including a winning port device, in which the opening/closing operations of an opening/closing winning port have originality and novelty and ball clogging by a plurality of game balls near the winning port is surely prevented. SOLUTION: A regular winning port device 15 includes a winning port body 21 movable over an advanced position at which it is advanced forward from the board surface 4c of a game board 4 and a regular winning port 15a is opened upwards and a withdrawn position at which it is moved back from the advanced position in a direction orthogonal to the board surface 4c and does not project from the board surface 4c, and a movement driving mechanism 22 for driving the movement of the winning port body 21 over the advanced position and the withdrawn position. When the winning port body 21 is at the advanced position, the regular winning port 15a is advanced forward from the board surface 4c and the upper part is opened. When the winning port body 21 is at the withdrawn position, the regular winning port 15a does not project from the board surface 4c and the upper part is closed. COPYRIGHT: (C)2010,JPO&INPIT
