Abstract
Apparatus for the application of different first indicia to successive envelopes for exposed photographic films and for the application of related different second indicia to associated films has a first marking unit which imprints first indicia onto successive envelopes and a second marking unit which exposes second indicia onto unexposed portions of films. The second unit is adjusted in automatic response to monitoring of adjustment of the first unit, and the two units can be actuated to apply related first and second indicia to an envelope and to the associated film only when the envelope and the film assume predetermined positions with respect to the corresponding units. The positions of successive envelopes and successive films are scanned by discrete first and second photoelectric cells. The first unit is adjusted by the first cell or in automatic response to completion of application of first indicia to an envelope. The second indicia are displayed on the control panel of the apparatus for observation by the attendants, and the control panel has switches for adjustment or resetting of a digital counter which forms part of the first marking unit.
