PURPOSE: To double the playing interest of a toy gun by setting an arbitrary number of shooting bullets by operating a changeover switch, transmitting an electric signal generated by triggering to a control signal circuit, and controlling the operation starting time, rotating speed, rotating time of a motor, the output of the motor, etc.

CONSTITUTION: A hammer crank 15 is once moved up and down at each revolution of a rotating mechanism 14 to shoot one bullet, and a motor 2 is rotated at a constant speed with respect to the shooting of one bullet in response to the gear ratio of a motor pinion 17 to mechanism 14. When a trigger 3 is pulled, its partial protrusion 18 presses a spring lever 20 of a signal switch 19, and a signal is generated in a signal generator 4 associated with an electric board 22 by turning ON, OFF the three contacts 21 of the switch 19. The pulse signal is fed to a control signal circuit 5 to form a control signal, thereby controlling the rotating time of the motor 2. If the rotating time of the motor 2 can be set, for example. to 0.12 set and controlled, the single bullet shooting mechanism of a toy gun can be controlled. It is rotated for necessary time in response to the single shooting mechanism or three-bullet continuous shooting mechanism to perform its purpose.
