<p>PURPOSE:To miniaturize and simplify a device by surely executing the head shifting of a play position and quick winding position by the structure deciding the turning direction of 1st and 2nd turning members according to the rotary direction of the cam gear of a positive and reverse rotary type. CONSTITUTION:The turning directions of 1st turning member 2 and 2nd turning member 3 are decided by the rotary direction of a cam gear 1. A head plate is regulated to a play position by locking the engaging part 5 of the head plate to the play side position regulating part 4p of the position regulating hole 4 of the 2nd turning member 3 at playing time. The head plate is engaged with the quick winding position by locking the engaging part 5 of the head plate to the quick winding side regulating part 4f of the position regulating hole 4 of the 2nd turning member 3 at quick winding time. The head plate can thus be shifted easily and surely by the simple structure of using the cam gear 1, 1st turning member 2 and 2nd turning member 3 only.</p> |
