A reader-printer incorporates a fiche film projecting system and a roll film projecting system in a compact module compatible with existing main frame designs for reader-printers. Both projection systems align with a common optical axis when in operative position. Simple control means operate through a lost-motion linkage to switch a fiche lamp and condensing lens assembly and a roll beam reflecting mirror assembly in ganged relation to locate each assembly in an out-of-the-way position when the other assembly is in operative position, with the lost-motion linkage also accommodating relative vertical adjustment between these assemblies. Novel mountings permit easy total removal and replacement of the fiche beam projection lens and selective shifting of the fiche beam condenser lens to an out-of-the-way position under the control of an apertured X-Y carrier for providing enlarged openings for the wider beam presented at these locations in the roll projection mode. A universally adjustable roll projection lens mounting and a solenoid actuated floating roll film gate mounting offer improved versatility and performance in the roll projection mode.
A convertible arrangement for selectively shifting fiche film projecting means and roll film projecting means into operative alignment with a common optical axis that intersects a fiche image plane and extends to a projection plane, the arrangement being characterized in that the fiche film projecting means includes beam projecting structure mounted for controlled shifting movement between an operative position of alignment with the optical axis and an out-of-the-way position spaced from the optical axis, the roll film projecting means includes beam projecting structure mounted for controlled shifting movement between an out-of-the-way position spaced from the optical axis and said operative position of alignment, and selectively operable control means interconnecting the fiche beam projecting structure and the roll beam projecting structure in ganged relationship to effect controlled shifting movement thereof for converting between a fiche film imput mode and a roll film input mode.
