Air Gun and Number-of-Shots Change Control Method

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. The present invention is an air gun comprising: a single-shot mode shooting operation ( 207 ) that starts when a trigger switch is switched ON ( 201 ), and stops when a reference position is detected; a repeating mode shooting operation ( 208 ) that performs the shooting operation continuously when the trigger switch is switched ON, and stops the shooting operation when reference position is detected; an N-shot mode shooting operation ( 209 ) that performs the shooting operation only N time when the trigger switch is switched ON, and stops the shooting operation when the reference position is detected; and a switching means ( 206 ) for selecting and operating any one from among the single-shot mode, repeating mode and N-shot mode operation.
