Claims

[Scope of utility model registration request]

A pair of reel stands are arranged at a distance from each other, and both of these reel stands are located at an intermediate position of S, and are arranged on a straight line at right angle S to a straight line connecting the centers of these two reel stands. first and second drive wheels; first and second motors that drive both of these drive wheels in forward and reverse rotation; first and second reel stands which are swung according to the rotational direction of the second drive wheel and are engaged directly with the two reel stands or indirectly through an intermediate wheel to selectively drive the two reel stands to rotate; With respect to the straight line connecting the center of both reel stands and the oscillating rotation axis of 2 and the center of both reel stands, it is possible to reciprocate between the first position and the second position along the parallel direction. When it is in the first position and when it is in the second position, one of the two cylinder swing rotation wheels is made swingable, and at the same time, the other one is restricted to a 5 intermediate position in the swing range. A mode switching device comprising a position regulating plate that alternately performs the following operations.
