摘要： PURPOSE:To selectively feed two types of cartridges to a bolt passage by a single feed wheel. CONSTITUTION:A cartridge type switch mechanism includes a feed wheel 32 that is rotatable mounted in a breechblock main body 12, two cartridge feed holes through which cartridges 16 are fed to both sides of the feed wheel 32 from a cartridge feeder, and movable stoppers 44 which are respectively provided in cartridge feed passages between the cartridge feed holes and the feed wheel 32. The stopper 44 can be shifted to a position where the stopper 44 protrudes into the cartridge feed passage to prevent the cartridge from being fed and to another position where the stopper 44 retreats from the cartridge feed passage to allow the cartridge to be fed. The feed wheel 32 rotates in the direction in which the cartridge 16 on the side of stopper 44 which is at the cartridge feed permitting position can be transferred from the cartridge feed hole to a bolt passage.

摘要： PURPOSE:To supply an ammunition without using a bullet feeder having a large moving space by so fluctuating the ammunition directed in a trunnion axial direction perpendicular to a gun axis gradually toward the gun axial direction, and then delivering the ammunition to a gun side. CONSTITUTION:An ammunition 80 fed from a trunnion axis 18 is received by bullet holders 34a, 34b of a bullet feed tray 28 at a bullet receiving position of a trunnion axis 14 side, and so fluctuated at 90 degrees by the tray 28 as to be gradually directed toward a gun axis G perpendicular to the axis 14. Thus, the ammunition 80 is received by a gun side at a bullet delivery position of the axis G side. That is, the ammunition 80 is delivered from the tray 28 to a slide 32. Thus, the ammunition 80 can be supplied by a small-sized unit without using a bullet feed guide unit having a large moving space like a flexible chute.

摘要： PURPOSE:To downsize a cam drum, a driving source and a driving spindle, and extend the life of the cam drum and an operating rod by a method wherein the load-feeding wheel begins to rotate while the operating rod is in backward stroke, and finishes a pitch of rotation while the operating rod is in forward stroke. CONSTITUTION:When a gun fired, a load (a) is received in a notch 4c of a load-feeding wheel 4. The load-feeding wheel 4 rotates a pitch while an operating rod 8 is backward-forward strokes, and the one load (a) is sent between the operating rod 8 and a barrel 1. Then, the one load (a) is loaded in the barrel 1 while the operating rod 8 is in forward stroke, and discharged when the operating rod 8 is at front stop stroke. That is, the operating rod 8 is sent by the load-feeding wheel 4 to load the load (a) into the barrel 1 and the barrel 1 is closed by a breech mechanism 3 to fire the load (a). Then, a cam drum 17 rotates, and the load-feeding wheel 4 begins to rotate while the operating rod 8 is in backward stroke finishes a pitch of rotation while the operating rod 8 is in forward stroke.
