<p>A photocopier with copy feed from roll form has several rolls of copy material (3) on a rotating holder (5) so that any roll can be selectively brought into the feed position, and retained there by ratchet slots (47) in the outside of the holder and a sprung ratchet lever (51). The holder carries different widths of copy so that the operator can choose the size of the copy without having to open the machine to change the copy material. Each copy roll is held in a slot in the support flange by separate spring loaded catches (11) and can be fitted and removed without special tools.</p> |
