[Effect of device]

 According to the invention of claim 1, an arbitrary energy gas can be introduced into the gun body from the outside of the gun body using an external hose, and a bullet can be fired by the energy gas. Even if an external hose is connected to the gun body, the valve of the gun body is closed and it is not possible to fire a bullet. Since the arm protruding from one end of the magazine opens the valve of the gun body, it cannot be shot unless the magazine is attached to the gun body. Therefore, a toy gun is the same as a real gun.

Also, a magazine of a type in which an energy gas such as liquefied gas is stored in the magazine can be used, and in that case, the external hose can be removed and the toy gun can be carried around lightly to fire a bullet. Therefore, depending on the situation at the site, it is possible to install a storage type magazine, or install a magazine that does not store energy gas and continuously supply energy gas by an external hose.

In addition to the above effects, the invention according to claim 2 is that the valve is always closed by the force of the valve spring in the opening / closing hole provided in the gun body, and the lower end of the valve is the second opening of the opening / closing hole. When the magazine is mounted on the gun body, the opening of the connecting hole in the arm of the magazine pushes the lower end of the valve upward against the force of the valve spring, and the side opening of the valve in the guide hole opens and closes. Since it is exposed to the large-diameter portion and the opening / closing hole, the guide hole, and the connecting hole are connected, the structure is extremely simple and operates reliably.
