In short, the present invention is constituted by the launching apparatus main body 3 having the loading hole 7 for the color bullet 2 and the cylinder 4 attached to the launching apparatus main body 3 and filled with the compressed gas. Since the bullet 2 can be ejected, the color bullet 2 can be accurately ejected over a certain distance. Further, since the ventilation path 10 from the tip of the cylinder 4 to the loading hole 7 is formed in the firing device main body 3, the color bullet 2 loaded in the loading hole 7 can be reliably blown by the compressed gas from the cylinder 4. . Further, since the opening / closing means 5 for the cylinder 4 and the means for preventing the firing of the color bullets 2 are provided in the launching device body 3, the color bullets 2 are not fired by operating only one of them, so that erroneous shooting can be completely prevented. Secure security measures can be taken. In addition, regardless of the physical ability of the person using the color bullet firing device 1, the color bullet 2 can be accurately shot within the range of the range, and the hitting rate can be improved. Further, if the color bullet 2 is simply loaded into the loading hole 7, the color bullet 2 is fired even at a low pressure. However, since the firing prevention means 6 is provided, the high pressure compressed gas acts on the color bullet 2. However, since the color bullets 2 are not fired unless the firing prevention means 6 is released, the range of the color bullets 2 can be extended, and the color bullets 2 can be positioned at the loading position by the firing prevention means 6. Therefore, it is possible to prevent the color bullet 2 from falling off during use.

Further, the opening / closing means 5 for the cylinder 4 is provided at the front end of the cylinder 4, and is opened and closed by pushing a valve body 11 a to open a closed jet port 11 b. Since it is constituted by a cam 12 which is movably provided and a tip of the valve body 11a contacts, simply rotating the cam 12
Since the compressed gas in the cylinder 4 can be filled in the ventilation path 10, the opening and closing operation of the cylinder 4 can be easily performed.

A stop pin 20 is provided in the firing device main body 3 at a position corresponding to the engaging portion 36 of the mounted color bullet 2 in the firing device main body 3, and a stop pin 20 is provided. Since the distal end of the projecting stop pin 20 is configured to engage with the engaging portion 36 of the collar bullet 2 by the driving unit 21, only the stop pin 20 is protruded and retracted. 3 can be easily incorporated.

The projecting / retracting drive 21 of the stop pin 20 is connected to a cylinder 21a provided on the side of the firing device main body 3 and a cylinder 21a.
A piston 23 movably disposed within 21a;
And a spring 24 disposed below the cylinder 23
The base end of the stop pin 20 inserted in the recessed hole 22 penetrating from the center of the end face of the end face 21a toward the loading hole 7 is fixed to the piston 23, while the communication path 27 between the ventilation path 10 and the cylinder 21a is formed. At the same time, an opening / closing means 28 is provided at an intermediate portion of the communication passage 27, and a switch 26 for operating the opening / closing means 28 is provided in the firing device main body 3, so that the stop pin is provided by utilizing the compressed gas in the cylinder 4.
Since the 20 can be immersed, other driving sources can be eliminated.

In the color bullet firing device 1 according to the fourth or fifth aspect, the compressed gas cannot be sent into the cylinder 21a unless the color bullet 2 is loaded in the loading hole 7. When the color bullet 2 is loaded into the used loading hole 7, the loading operation is troublesome with the stopper pin 20 being in a protruding state.
a, the distal end of the operating screw 41 is screwed into a screw hole 43 at the center of the piston 23 opposite to the stop pin 20, and the screw head 42 of the operating screw 41 is launched. Since the cylinder 21a and / or the piston 23 are structured so that the piston 23 does not rotate in the cylinder 21a, the color bullet 2 is not loaded in the loading hole 7 while the cylinder 21a and / or the piston 23 is projected. Even if the compressed gas cannot flow into the cylinder 21a, the stop pin 20 can be made to protrude and retract only by operating the operation screw 41 in the forward and reverse directions.
The practical effect is remarkable, for example, the loading work of the color bullet 2 can be facilitated.
