ABSTRACT:
An apparatus for reading optical code on a moving web of photographic film includes a first frame (84); a pair of parallel tracks (132, 134) supported by the fast frame; a pair of carriage members (138, 140) mounted for movement along the tracks; a pair of oppositely facing edge guides (148, 156, 158) each supported by one of the carriage members, each edge guide including a serpentine contact surface (160) with a central portion (162) for engaging an edge surface of a moving web; and a mechanism (106-120) for moving the carriage members back and forth along the tracks; and a pair of flexures (122, 124) for resiliently engaging the mechanism for moving with the carriage members, to resiliently load the edges of the web. The apparatus further includes a second frame (70, 186, 248); a pair of film deflectors (262, 264) supported by the second frame; and a mechanism (74-96, 180-238) for relatively positioning the two frames with the film deflectors at least partially engaging the film with the serpentine contact surface, the mechanism being selectively adjustable to vary the deflection of the web toward the serpentine path, so that webs of different types of photographic film can be constrained. One or both of the carriage members may support an apparatus (274, 276) for reading optical code on an edge of a web of photographic film. The reader includes a housing (284) having a slot (286) through which an edge of the web may be transported; a light source (290) mounted on one side of the slot; a code reader (294) mounted on the other side of the slot; a frame (138, 140) for supporting the housing; and a mechanism (302-310) for moving the housing relative to the frame to adjust a location of the code reader relative to an edge of a web.
