PROBLEM TO BE SOLVED: To provide a Pachinko game machine capable of solving a problem of the bite-in of balls, and preventing fraudulent acts of the player by supporting a security board to the body of the game machine in such a manner as to be opened and closed from the game board side and constituting the security board in such a constitution as to be locked in an unlockable manner to the body of the game board when the security board is closed and the bite-in of the balls can be eliminated in the state of being locked. SOLUTION: The security board S has a holding frame 61 so supported to the body of the game machine as to be opened and closed. A displacement board member 62 is assembled into the holding frame 61 so as to be displaced in the back and forth direction. By the turning operation of a tool T, a displacement mechanism B1 displaces the displacement board member 62 between the original position and an advanced position by a drive mechanism member RPa, an up-and-down movement mechanism member RPb, an upper guiding member RPc, and a lower guiding member RPd. By the turning operation of the tool T, a locking mechanism RP2 locks the security board S in an unlockable manner to the body of the game machine by means of a lock lever 74.
