PROBLEM TO BE SOLVED: To provide a Pachinko game machine which prevents a fraudulent act committed through a gap between a front door and an upper tray member, while the upper tray member is allowed to be opened in a state where the front door is closed. SOLUTION: An upper tray panel 20 is attached with a movable member 30 formed with a groove portion 31, and the position of the movable member 30 is variable between a normal positionαwhere the groove portion 31 has a height allowing a shield plate portion 42 of the front door 6 to be inserted therein and a retreated positionβwhere the groove portion 31 has a height not allowing the shield plate portion 42 to abut thereon. According to this structure, when the front door 6 and the upper tray member 7 are closed, the movable member 30 at the normal positionαengages the shield plate portion 42 and the groove portion 31 to each other so as to prevent easy intrusion of a fraudulent device from the gap between the front door 6 and the upper tray member 7. When the front door 6 and the upper tray member 7 are opened, the movable member 30 at the retreated positionβallows the front door 6 to turn to the back side of the upper tray member 7 without collision between the shield plate member 42 and the groove portion 31 so as to close the front door 6 while opening the upper tray member 7.
