Patent ID: 7231841

Claim:
An operating mechanism for a reciprocating component, comprising: a moving member having a mounting section to be attached to the reciprocating component, a first gear, a second gear for engaging the first gear to rotate in reverse when the first gear rotates forward, and an accumulating device for accumulating a rotational force to rotate the second gear forward when the second gear rotates in reverse, and a base having a guide for guiding the moving member to move forward and backward, said guide having a backward path guide section and a forward path guide section facing the backward path guide section so that the moving member accumulates a backward travel force when the moving member is guided along the backward path guide section to move backward to a mid point and the moving member fully moves backward with the accumulated backward travel force from the mid point, said moving member accumulating a forward travel force when the moving member is guided along the forward path guide section to move forward to the mid point and fully moving forward with the accumulated forward travel force from the mid point, wherein said backward path guide section includes a backward path accumulation zone for engaging only the first gear, and a backward path release zone located ahead of the backward path accumulation zone for engaging only the second gear; and said forward path guide section includes a forward path accumulation zone for engaging only the first gear, and a forward path release zone located ahead of the forward path accumulation zone for engaging only the second gear, wherein said moving member is rotatably attached to the reciprocating component with the mounting section of the moving member so that rotational centers of the first gear and the second gear swing about a position where the moving member is attached to the reciprocating component, and wherein said moving member further includes a damping gear for receiving a damping force and a third gear for engaging the damping gear and the second gear.
