Abstract
In order to be able to simply and rapidly replace a printing plate on the franking head of a franking machine without the hands or the surrounding area being exposed to a risk of dirtying, an automatic change mechanism is provided in the franking head, as well as in and on an interchangeable magazine. An electromotive drive bring about the disengagement and discharge of the printing plate from the franking head into the circumferentially fixed, but detachably secured magazine. Ratchet levers and ejecting levers mounted in the franking head are used for this purpose. These levers are driven by cam bodies, while a similar group of stop levers and delivery levers mounted in the interchangeable magazine is operated by electromagnets. An ejecting lever loaded by a spring presses against the back of the cassette, so that after the release of a latching means the cassette is moved out by means of a pawl on guide bolts. It can then be removed in simple manner with the printing plate enclosed therein and can be replaced by another interchangeable magazine with another printing plate.
