ABSTRACT:
A winding device includes: a winding core capable of taking up an elongated photosensitive material; a guide member for forming a guide passage for the photosensitive material between the guide member and an outer peripheral surface of the winding core in a state in which the guide member is wound around the winding core; a guide arm which is rotated to allow a distal end thereof to be brought into contact with the winding core and adapted to guide the photosensitive material and the guide member along the guide arm from a proximal end side toward a distal end side of the guide arm; and a guide-member accommodating portion which is rotatively driven to pay out the guide member so as to cause the guide member to be wound around the winding core. Accordingly, a leading end portion of the photosensitive material is wound around the winding core for taking up the photosensitive material with a simple mechanism, and the guide member for causing the leading end of the photosensitive material to be wound can be accommodated compactly, thereby improving the operating efficiency at a time when the photosensitive material wound in roll form is removed.
