Patent attributes
The present invention relates to a drum magazine, and more particularly, to a drum magazine in which a wheel cover, which is configured to provide an elastic force via a mainspring to a bullet guide unit configured to elastically support a bullet loaded in a drum at a loading hole which is an inlet of the drum, is rotatably disposed at an outer surface of the drum, wherein, at the time of loading, an elastic latch unit is elastically engaged with an inner ring gear of the wheel cover and allows rotation of the wheel cover only in one direction so that a loading space at an entry of the loading hole that is provided due to arbitrary rotation of the wheel cover in the one direction is maintained as it is even when a user removes his or her hand from the magazine, and, after the loading is completed, a latch control unit configured to disengage the elastic latch unit and the inner ring gear is operated so that an elastic restoration force of the mainspring, which is accumulated due to the loading, is transmitted to the bullet guide unit and the loaded bullet is elastically supported at the loading hole.
