As described above, the medicine chamber cover 23 is pushed backward by the projection 29 provided on the inner circumference of the front portion of the cylinder 8, and the pin 24 fixed to the medicine chamber cover 23 passes through the hole in the front wall of the cylinder chamber 16 and the bolt in the cylinder chamber 16 The umbrella portion 18 is pushed backward, and the bolt 18 retracts in the cylinder chamber 16 by about 1/3 and stops as shown in FIG.

All the gas in the cylinder chamber 16 is discharged in the direction of the muzzle at the front end of the inner barrel 14, and the breech pad 28, which lost its inertia due to the backward stop of the piston rod 19, is
Due to the restoring force of the ammunition 33 compressed during the backward movement, the forward movement is started in an attempt to return to the original position.

The piston rod 19 advances together with the play bottom 28 by the force of the ammunition 33, the piston 21 hits the umbrella portion of the bolt 18 during the advance, and the protruding shaft 20 causes the bolt 1 to move.
8 into the through hole 17 and the bolt 18 into the cylinder chamber 1
Push to the front end of 6.

At the time of this forward movement, the bolt 18 is pushed up to the uppermost stage of the bullet storage chamber 3, one half of which is pressed by one locking edge 9 and the other half between the locking edges 9 and 9 on both sides. The exposed bullet 6 is pushed forward and sent into the bullet gripping chamber 15 as the breech plate 28 closes, ready for the firing of the next bullet.

Therefore, by further pulling the trigger 34, the series of operations described above is repeated, and the next bullet can be fired.

In this manner, the back and forth movement of the playground 28 can be performed in the same manner as a real semi-automatic pistol, and the plastic spherical bullets 6 can be continuously fired.

In the above embodiment, the bullet holding chamber 15 and the inner barrel 14 are separated, but they may be integrated and an inner barrel having a bullet holding chamber at the rear end may be used. Also, the above-mentioned magazine 5 has a bullet storage chamber 5
The gas storage chamber 4 is provided in the gun body 1, and the gas storage chamber 4 may be provided only with the bullet storage chamber 5.
