<p>PURPOSE:To miniaturize and simplify a device by surely executing a play position and head shifting by the structure deciding the turning direction of 1st and 2nd rotary members according to the rotary direction of the cam gear of positive and reverse rotary type. CONSTITUTION:The turning direction of a 1st turning member 2 and 2nd turning member 3 is decided by the rotary direction of a cam gear 1. A head plate is then adjusted to a play position by locking the engaging part of the head plate with the play position regulating part 4p of the position regulating hole 4 of the 2nd turning member 3 at playing time. On the other hand the head plate is regulated to quick winding position by locking the engaging part 5 to the quick winding side position adjusting part 4f of the position adjusting hole 4 of the 2nd turning member 3 at quick winding time. And by fixing the 2nd turning member 3 by exciting a solenoid 6, the head plate can be held at the quick winding position surely via the 2nd turning member 3.</p> |
