Abstract

PURPOSE: To prevent extension of or damage on a film-like dedium during letting off the medium from one take-up roller and winding up it around the other take- up roller by providing movable rollers for absorbing the tensile force.
CONSTITUTION: A film-like medium 1 is let off from a take-up roller 2a and wound up around a take-up toller 2b, the two take-up rollers 2a and 2b being rotated at the same speed. As the let-off amount at the roller 2a becomes different from that take-up amount at the roller 2b so that the tensile force on the medium 1 increases, a lever 6 moves against the biasing force of a spring 7 to urge movable rollers 3a and 3b toward a fixed roller 5, relaxing the tensile force. As the tensile force decreases, the lever 6 is moved by the biasing force of the spring 7 to urge the rollers 3a and 3b away from the roller 5, compensating for the decrease in the tensile force. With a motor 11 rotated in the reverse direction, the medium 1 is transfered in the direction of the broken-line arrow.
