Abstract
A take-up apparatus for reel material of an image exposing device has a driven winding drum and a sensor provided to control the drive of the winding drum. The sensor detects the position of the reel material ahead of the winding drum. In this case, the drive of the winding drum is controlled in such a manner that the reel material forms a bulge (A) ahead of the winding drum with a substantially constant curvature.
