PROBLEM TO BE SOLVED: To provide doors individually opening/closing two big winning ports arranged horizontally and closely, to effect various changes in game contents by making differences in speed of an opening operation and the speed of a closing operation of each door and using them respectively according to a game progression, and to individually detect opening/closing states of the two doors with a single magnetic sensor. SOLUTION: The Pachinko game machine includes: a first door opening/closing unit 29 driving a first door 26 to open/close; the second door 41 opening/closing a second winning port 40 adjacently arranged on a side of a first winning port; and a second door opening/closing unit 44 driving a second door to open/close. The first door is constituted to be driven to open/close without a time lag from an operation of a first opening/closing mechanism and the second door is driven to open/close with a time lag from an operation of the second opening/closing mechanism. The first door and the second door have magnets respectively, and a single magnetic sensor is arranged between the respective magnets to detect the magnets provided on the doors with the magnetic sensor only when either one of the doors is at an open position.
