<p>PURPOSE:To push back a tension arm to a prescribed position by providing a projecting part which abuts on the tape tension control arm and turns it in a pushing back direction on a lever having a tape whole width erasing head. CONSTITUTION:When a tape drawing post table 1 moves to a position Y from a position X along a guide groove 11, a tape drawing post 2 pushes the lever 3 having the tape whole width erasing head 4 and turns it. Simultaneously with this turning, the projecting part 3c of the lever 3 pushes the member 8 of the tension arm 6 in the direction shown by an arrow H. Then, the member 8 is pushed in the direction shown by an arrow D by the tape drawing post table 1. Thereafter, the tension arm 6 is turned in the direction shown by an arrow E by the movement of the tape drawing post table 1. Finally, the tension arm 6 is pushed back to the position Z by positioning the tape drawing post table 1 at the position Y.</p> |
