<p>PURPOSE:To simplify the mechanism for miniatrization and reduction of the cost by switching the revolution modes of four reel turn tables for forward, reverse, fast forwarding and rewinding actions just by changing the revolving direction of a notor and sliding a head die. CONSTITUTION:A motor 1 can be revolved forward and reverse and the revolutions of the motor 1 are transmitted to a flywheel 2 and an intermediate pulley 4 via a belt 3. Both a fast feed gear 5 and a rewind gear 6 engage a gear 4a and a gear 4b engages a take-up idler gear 8. Then a take-up gear 9 and a reverse take-up gear 10 engage the gear 8. An FR arm 14 and a take-up arm 15 receive the revolving force in he revolving directions of the pulley 4 and the gear 8 respectively. While a head die 13 can slide in the direction A-B and the cam parts 13a and 13b are provided for control of the rotation of both arms 14 and 15.</p> |
