Abstract
There is hereinafter provided a reciprocating/oscillating structure for use in a fishing reel, wherein the guide carries a guide slot within it that is asymmetric in shape, and that creates two separate spool movement velocity regimes as the spool is moved forward and backward during recall of fishing line into the reel. The guide slot of the instant invention is asymmetrically constructed to produce, in a two-cycle-type spool movement arrangement, one spool velocity profile in the forward direction and a different spool velocity function in the rearward direction. In the preferred embodiment, the two velocity profiles (asymmetries of the guide) will be chosen to be complementary in the sense that imperfections in the velocity function in one direction can be compensated for to some extent during movement in the second cycle.
