    • PURPOSE:To enable a free changing-over between a full automatic operation and a semi-automatic operation by a method wherein a launching device is provided with a trigger follower piece pivoted at a trigger in such a way as it is supported by a changing-over lever, its upper end is inclined to be always positioned at a lower surface of a reciprocating bar under a full-automatic operation and its upper end rises at a leading end of the reciprocating bar under a semi-automatic operation. CONSTITUTION:A trigger follower piece 21 is energized by the third spring 23 under a full automatic operation and inclined up to such an angle as one to be supported by a changing-over lever 29. Before a trigger 17 is pulled, a projection of the trigger follower piece 21 is abutted against a lower surface of a thick part 27 of an oscillating bar 25 and its upper end is positioned at a lower surface of a reciprocating bar 30. In turn, under a semi-automatic operation, the changing-over lever 29 is slid forwardly and moved and then locked. The trigger follower piece 21 is raised at an upright position against a spring force of the spring 23. At this time, the oscillating bar 25 is not rotated and a position of the pivot pin 22 is not displaced. Upper end of the trigger follower piece 21 is released from the lower surface of the leading end of the reciprocating bar 30 and flied out forwardly of the leading end of the reciprocating bar 30.
