摘要:
A rack assembly for a photographic roller processor is provided with plastic side frames for supporting rollers mounted between the side frames. The plastic side frames are provided with axially aligned roller bearing apertures and roller bearing pin apertures which support the rotatable rollers. The roller bearing aperture is made larger in diameter than the roller to provide a bearing surface for the roller and permits the roller to be installed between the side frames by inserting the roller through the roller bearing aperture from outside the side frame.

An automatic splicer (10) is provided which is coupled to a continuous running processor (14). Short strips of roll film (12) are inserted into the splicer (10) and are automatically spliced together as they are advanced through the splicer (10). When no film is ready to be processed a leader (56) is automatically spliced to the last roll of film (12') to be processed. When the last roll (12') of film is passed through the processor (14), the system may be placed on standby or stopped. Electronic control circuitry (100) senses by sensing switches (LS-1) in dancing-roll take-up station 13 when no more film is available for processing and energises leader paper drive rolls (57, 58)) to drive leader paper 56 to the trailing edge of the last film (12') between splicer blocks (26, 27). The control circuitry (100) controls a film drive motor (61), a splicer tape drive motor (70), a leader knife relay (71), and a splicer motor (69). Film (12) is sensed by the control circuitry (100) by means of a set (83) of photocells (S-1, S-2, S-3, S-4, S-5) between input feed rolls (17,18) and pinch rolls (21).

A photographic printer apparatus (10) is provided, with quick change self-threading magazines (14) of photographic material (67) which enables use of different widths and types of photographic material (67) at the input of the printer apparatus (10). A cutter station (55) is positioned within the printer console (11) adjacent the magazine input, where roll material (67) is pre-cut to the desired size of the photographic print (28) to be made before being exposed. Transport systems are provided in the console (11) for vacuum guidance and positioning of the photographic material (67) while it is being cut and for accurately positioning the photographic material (28) opposite a first exposure station (27) for exposure, and for transporting the piece (28) of photographic material to a second exposure station (29) or for storage and subsequent processing or to a continuously running processor adapted to develop, and wash and dry the previously exposed photographic material (28).
