PURPOSE:To reduce mechanical faults and ensure proper mechanical performance in shooting by providing an air compressor, a means to bring a projectile to the entry of a gun barrel, and a means to release the projectile from the muzzle by polling the trigger. CONSTITUTION:A pull at the trigger 4 turns on a microswitch 25, thereby actuating a microcomputer 23 to open an electromagnetic air valve 10 by a relevant instruction so that a current of highly compressed air is made to flow from an air compressor 6 into a pipe 5 only for a short time under control by a timer in the microcomputer 23. Then, a projectile 11 which has been at the entry of a gun barrel 2 is forced through an elastic O ring 24 and into the gun barrel 2 to be shot from the muzzle 3. Since, in performance of this procedure, a projectile 11 is brought to the entry of the gun barrel 2 before the trigger 4 is pulled, the shooting gives the same feeling as in actual firing even without fitting the gun 1 with an air compressor 6 or the like and, with the help of an increased velocity at which the projectile travels, is enabled to score hits at a high rate. Moreover, mechanical faults are reduced and proper mechanical performance is ensured in shooting. |
