<p>PURPOSE: To simplify the coupling mechanism while reducing leakage of gas by fitting a pipe connected with an inner magazine airtightly to a bullet feed pipe, enlarging the forward end of the connecting pipe by the forward end of the bullet feed pipe thereby feeding the bullets sequentially from the inner magazine to a bullet charging member. CONSTITUTION: When a pipe 28 connected with an inner magazine 7 charged with bullets 11 is fixed to a bullet feed pipe 25 at a machine section 4, the inner wall of a connecting member 28c and the outer wall of the bullet feed pipe 25 are held airtightly through an O-ring and gas is not leaked to the outside even if gas pressure spreads through the opening 13 of the machine section 4 into the inner magazine 7. A shopper 30 provided at the forward end of the tubular member 28a of the connecting pipe is released through action of the pipe 25 and a slit 29 and the bullets 11 can be fed constantly to the machine section 4. When the connecting pipe 28 is removed from the bullet feed pipe 25, the forward end of the tubular member 28a shrinks resiliently to block launching of the bullet 11 from the inner magazine 7.</p> |
