Abstract
A pair of sorting gates are fixed respectively to a pair of moving shafts that are disposed facing with each other so as to be able to move horizontally along the same straight line, and when a sorting gate is moved horizontally from a retracted position to a forwardly moved position interrupting the moving path of a sorting pin accompanying a forward motion of one of the moving shafts to which is fixed the sorting gate, the moving shaft at the forwardly moved position functions as a stopper member for the other moving shaft that is at the retracted position, and obstructs the forward motion of the moving shaft that is at the retracted position.
