PURPOSE:To avoid the mis-switching to automatic stop and automatic repetition, by locking the arm and lever temporarily and turning the lever after latched projection is passed by. CONSTITUTION:When a winding reel stand 7 turns toward the arrow, the arm 11 also turns toward the arrow, and the automatic stop lever 14 turns clockwise. Thus, the latch projection 14b is along the inner-circumferential wall 15d of the eccentric circular groove 15a of the gear 15, and when the stand 7 turns to opposite direction, the lever 14 turns counterclockwise, and the projection 14b is along the external circumferential wall of the cam stand 15b. Further, when the tap run stops and the stand 7 stops, the arm 11 is made free. Thus, after the gear 15 turns and the projection 14b passes through the narrowest groove 15a1, it locates on the locus and latches with the projection 15c on the locus. Thus, the lever 14 is lifted up, and the switch 20 for automatic reverse and automatic stop is on via the stop lever 19. |
