<p>A model gun with automatic bullet supplying mechanism comprises a pressure accumulating chamber (43) from which a gas leading passage (44) extends, a slider (60) movable along a barrel structure (2), a pressure receiving portion (61A) fixed in the slider (60) at the back of the barrel structure (2), a movable member (20;70) provided with first and second inner spaces (23;73, 24;74) and arranged at the back of a bullet holding chamber (4), a passage connecting portion (47;77) provided at the outside of the movable member (20;70) for connecting the gas leading passage (44) to the first and second inner spaces (23;73, 24;74) in the movable member (20;70), and a movable valve (46;76) provided in the passage connecting portion (47;77). The movable valve (46;76) is operative selectively, during a period in which the gas leading passage (44) is connected through the passage connecting portion (47;77) to the first and second inner spaces (23;73, 24;74) in the movable member (20;70), to cause gas derived through the gas leading passage (44) from the pressure accumulating chamber (43) to act through the first inner space (23;73) in the movable member (20;70) on a sham bullet (BB) in the bullet holding chamber (4) and to shut off gas flow to the bullet holding chamber (4) through the first inner space (23;73) in the movable member (20;70) from the gas leading passage (44) so that the gas derived through the gas leading passage (44) from the pressure accumulating chamber (43) acts through the second inner space (24;74) in the movable member (20:70) on the pressure receiving portion (61A) to cause the pressure receiving portion (61A) to move back in company with the slider (60). <IMAGE></p> |
