<p>A stopper (23) controls the opening or closing of an air flow channel. A small amount of air flow into a minor air channel (616) causes a pressure difference between the front and rear air pressure chambers (613a,613b) of a flow guiding piston (62), shifts a delivery tube (64) forward and pushes a paintball (B) a little forward. The paintball (B) is discharged by a thrust of air flow into a major air channel (612).</p> |
