ABSTRACT:
A transfer type copier having a rotatable drum of the type containing a long web of photosensitive material therein. The rotatable drum has a lid and a drum body, the lid being movable to permit replacement of the web and also to permit the web to be moved stepwise from inside the rotatable drum to the periphery thereof in order to position a new portion of the web on the drum body. The drum lid is movable to two positions, one of which permits the web to be removed and changed and in which the drum body is rotatable but not the lid, and the other in which the web can be moved stepwise and in which the lid remains rotatable with the drum body.
