The device comprises a sheath (10) which receives an electromagnetic means (12) for moving a movable piston (34) within the sheath (10) between a thrust nose (14) sealing a front (10-1) of the sheath provided with a projection tube, and a breech (18) sealing a rear (10-2) of the sheath. The invention also relates to a method for controlling the device.

Abstract: A simulation gun in which an air current is ejected by an operation of a piston mechanism portion to fire a bullet, a piston stop which is movable relative to a piston mechanism portion is provided, the piston stop is attached to one constituent member of the piston mechanism portion to absorb an impact force accompanying the operation of the piston mechanism portion, and shock-absorption means is provided between the piston stop and the other constituent member of the piston mechanism portion.

Abstract: A gun includes a bolt, a bolt stop member and a shock-absorption device. The bolt is movable forward or backward in a gun body, accumulates a pressure of a buffer spring while moving backward according to manipulation of the gun, and moves forward by releasing the accumulated pressure. The bolt stop member stops the bolt moving forward. The shock-absorption device includes a shock-absorption link which engages with a shock-absorption shaft which acts on the bolt stop member to absorb an impact force applied to the bolt stop member by the engagement of the bolt and the bolt stop portion.

Abstract: A switching mechanism that controls a drive circuit of an electric motor in order to select any one of a single shooting mode, and a successive shooting mode. The switching mechanism includes a selector unit which is provided in order to select between the single shooting mode and the successive shooting mode, a switch which closes the drive circuit in response to an operation of a trigger, and a cut-off member which turns off the switch when the single shooting mode is selected. An engagement location for the movable portion and the cut-off member in the piston cylinder mechanism is set in a front portion in a direction of the reciprocating operation of the movable portion, and a range of selecting a time taken until the front portion engages with the cut-off member after the movable portion starts to retract can be lengthened.

Abstract: A gun includes a bolt member that is disposed in a gun body so as to be movable forward and rearward, that moves rearward in response to gas pressure generated by bullet shooting so as to compress a bolt spring, and that moves forward in response to release of the compressed pressure so as to perform a bullet loading operation, and a bolt stop that stops forward movement of the bolt member. The bolt stop (31) has engagement means (36) for engaging with the bolt member which moves forward to reach the engagement means (36) after last bullet shooting, and includes buffer means (40) for buffering an impact force applied to the bolt stop due to the engagement so as to act on the bolt stop.

Abstract: A sight adjustment device, which adjusts a course of a bullet to be shot when shooting the bullet loaded in a cartridge portion of each of barrels, in a simulation gun having a plurality of the barrels includes a plurality of pressurization members that add pressure to the bullet loaded in each cartridge portion such that rotation is applied to each bullet; link members that are provided on a side of a gun main body such that one end portion is disposed on a side of the pressurization members and the other end portion is disposed on a side of operation units, and transmit operations of the operation units to the pressurization members; and the operation units that are provided on the side of the gun main body in order to adjust a backspin amount.

Abstract: An electric gun having a plurality of barrels includes a plurality of cylinders each of which serves as a compressed air generating unit, and positioned at rear portions of the plurality of barrels, each of which has an air-blast nozzle at a tip end, and a reciprocating piston; a piston assembly with a plurality of pistons which respectively reciprocate inside the cylinders and generate compressed air, binds the plurality of pistons in one place by using a joint portion at the rear, and is integrally provided with one piston shaft, having a rack along a reciprocating direction and the joint portion; and an electric mechanism that causes the piston assembly to retract, causes an elastic member to accumulate pressure, and drives an output gear meshing with the rack in order to compress air by releasing the accumulated pressure.

Abstract: A system where an attachment angle between an output gear of a motor holder and an input gear of a gear box is displaceable. A piston cylinder mechanism is driven by an electric mechanism. An output gear and input gear are bevel gears. Connection portions are provided in at least two places on a gear box side, and connection counterpart portions are provided on a motor holder side. The connection portions are present on the same circumference about a rotary shaft of the input gear and on both sides across a radial-directional axial line passing through the rotary shaft and angles A, B formed by axial lines respectively connecting the connection portions. The rotary shaft and the radial-directional axial line are set so as not to be equal to each other (A?B).
