摘要

A model gun with automatic bullet supplying mechanism, which comprises a slider (50) provided to be movable along a barrel (2), a movable member (54;65) provided between a bullet holding chamber (4a) provided at the back of the barrel (2) and a pressure chamber (56;62) with variable capacity provided in the slider (50), and a gas passage controller (25) provided to be movable in the movable member (54;65), wherein the gas passage controller (25) is operative selectively to control a first gas passage (21) extending from a pressure accumulating chamber (33) through the movable member (54;65) to the bullet holding chamber (4a) to be open so that gas discharged from the pressure accumulating chamber (33) is supplied through the first gas passage (21) to the bullet holding chamber (4a) and to control a second gas passage (22) extending from the pressure accumulating chamber (33) through the movable member (54;65) to the pressure chamber (56;62) to be open so that gas discharged from the pressure accumulating chamber (33) is supplied through the second gas passage (22) to the pressure chamber (56;62) to cause each of the slider (50) and the movable member (54;65) to move back for making preparations for supplying the bullet holding chamber (4a) with a sham bullet (BB) from a magazine (31) for containing sham bullets.
