Fired by the biasing force of 44. At this time,
The spiral projection 50c of the tail portion 50b of the bullet 50 and the guide groove 48e of the spring accommodating portion 48d are loosely screwed together to form the projection 5
When 0c passes through the guide groove 48e, a rotational force in the axial direction is applied, and the gyro effect works to maintain the flight posture, so that the warhead 50a moves forward in front of it while making a rotational motion and stably. It is safe because there is always a cushion part even if it hits a person in advance.

Subsequently, when the current still flows and the rib gear 34 further rotates, the pin 34c is disengaged from the cam rib 36a, and the cam ring 36 is stopped by the inner diameter cam 36b.
It stops at the position where it got over the boss 403b. When the rib gear 34 further rotates, the first rib 34a comes into contact with the hook boss 38a, moves the movable hook 38 to the right and comes to the same position as in FIG. 12, and the second rib 34b comes into contact with the hook boss 38a and the rib gear 34 moves. The rotation stops. Second
When the signal is cut off, the rotating torque of the motor 28 disappears, so that the movable hook 38 is pulled back to the left and returns to the state of FIG. 14 again, and the rib gear 34 becomes rotatable. Here, when the third signal is sent, it operates in the same manner as the above second signal, and then the stopper blade 404b is pulled down and the next loaded bullet is fired. This causes the loaded bullet to be fired once for each signal and not continuously while the signal is being emitted.

In the above embodiment, the structure 15 has been described as an example in which the first position and the second position are moved by the compression coil spring 42 by the hook mechanism, but it may be moved by another method. For example, this structure unfolds, is pivoted,
It can be extended, unfolded, opened, or moved or rotated forward, backward, or left or right outside the vehicle, and any movement can be performed. Furthermore, it is clear that the structure can also be moved by a reversible actuator so that the structure can be moved up and down between the first and second positions.

Further, in the above-mentioned embodiment, the mechanism capable of firing only 5 bullets 50 is shown, but it is obvious that a larger number of bullets can be fired by the same mechanism.

Although radio signal control was chosen, the control unit could be wired to the vehicle 10. Control signals can be sent over the wire from the remote control unit for the operation of the vehicle, or electric drive signals can be sent directly from the remote control unit to drive circuits mounted on the vehicle.

Although radio radio control was used, other radio controls including infrared and ultrasonic signals can be used. Power is amplified directly by a signal generator or by an amplifier, which responds to the transmitted control signals that the vehicle receives to control a relay or other switch that supplies a more powerful current to each motor or actuator. After that, or by a control signal generated by the vehicle processor, it may be supplied to the electric actuator of the vehicle.

While the preferred embodiment of the invention has been disclosed and suggested many modifications, others can be made in the art. Therefore, the present invention is not limited to the disclosed preferred embodiments and other embodiments, but will be further shown in the scope of claims.
