摘要： A model gun with automatic bullet supplying mechanism, which comprises a slider (12) provided to be movable along a barrel (3) and a movable member (15) provided between a bullet holding chamber (4) and a pressure receiving portion (30A) to be movable along moving directions of the slider (12). A first gas guiding passage (35) for guiding gas supplied through a gas leading passage (45) from a pressure accumulating chamber (40) to the bullet holding chamber (4) and a second gas guiding passage (36) for guiding the gas supplied through the gas leading passage (45) from the pressure accumulating chamber (40) to the pressure receiving portion (30A) are provided in the movable member (15) to be coupled with each other and, during a period in which the gas leading passage is opened by a movable valve (42), the movable member (15) is operative to cause gas pressure to act on a sham bullet (BB) in the bullet holding chamber (4) so as to move the sham bullet (BB) forward from the bullet holding chamber (4) and, after the sham bullet (BB) has moved forward from the bullet holding chamber (4), to cause gas pressure to pass through the first gas guiding passage (35) and simultaneously to act on the pressure receiving portion (30A) so as to move the pressure receiving portion (30A) back with the slider (12), in accordance with the difference in resistance against gas flow between the first and second gas guiding passages (35, 36), and further to move back together with the slider (12) for making preparations for supplying the bullet holding chamber (4) with a sham bullet (BB) from a magazine (38).

摘要： 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).
