<p>PURPOSE:To make a mechanism thinner by arranging a rack driving the drawing member of a magnetic tape drawing means in the space between a motor for driving a cylinder with its turning and a capstan motor transferring the magnetic tape. CONSTITUTION:A work gear 9 is rotated by the revolution of a motor 8, this power rotates a wheel gear 10 and then a cam gear 7. The arm pin 6a of a rack operation arm 6 is engaged with the cam groove 7a of the cam gear 7 and when it works from storing state to drawing state, the cam gear 7 is rotated in clockwise direction and the rack operation arm is lifted according to the displacement of the cam groove 7a, the rack 1 connected with the rack operation arm 6 in lifted as well. Since the toothed-wheel 1b provided on the rack is biting with a toothed-wheel 5 the toothed-wheel 5 is rotated as per an arrow mark, a drawing base 2a is moved thereby and a magnetic tape can be drawn by a drawing member 2.</p> |
