Abstract: A feeder B as shown in FIG. 1 is constructed so that a nozzle unit (2) is located in a cylinder unit (11) of a bullet-firing unit (1), and that in response to the movement of a piston unit (12) is capable of being connected to or disconnected from the piston unit (12), and where a bullet-feed port (3b) can be closed or opened. Furthermore, with a force that is greater than the force of an elastic member (nozzle spring) (22) and a force that is less than the engagement force between a locking section (21a) and a locked section (12g), a joint unit (124) connects the piston head (121) with the piston body (123), and within a limited space, efficiently increases the amount of time that the bullet-feed port (3b) is open. In this way, it is possible to improve durability of the feeder and increase reliability of feeding bullets, as well as it is possible to reproduce the operation of a real gun that can be taken down. Moreover, it is possible for the user to easily replace the feeder.

Abstract: The present invention relates to an electronic control method for an air gun in the form of a model gun, and that is capable of easily detecting whether there are bullets in the magazine, and preventing blank shooting operation. The air gun of this invention comprises a method for prohibiting the shooting operation for the air gun by receiving a detection signal indicating a state of no bullets from a bullet-detection lever, which is located in a magazine in which a plurality of bullets are stored, and that by setting it in an air gun, continuously feeds said bullets into the chamber of the air gun, and that detects whether there are any bullets stored in the magazine.

Abstract: The present invention relates to electronic control of an air gun in the form of a model gun, and that after any kind of shooting operation performs control so that a rotating wheel (sector gear) returns to a position where it does not mesh with a rack, and in so doing, improves the reliability of the mechanical mechanism of the gun, prevent degradation of the spring effect of the spring, and furthermore makes it possible to open the inside of the gun and to perform maintenance easily.

Abstract: This invention relates to electronic control of an air gun in the form of a model gun, and in a repeating mode operation is capable of easily controlling the number of shots, and furthermore is capable of easily switching among single-shot mode, repeating mode and N-shot mode. Also, it is possible to always stop the shooting operation at a specified position.
