ABSTRACT:
This disclosure relates to a lens shuttle mechanism for a microfilm camera. The lens system (25) is mounted in a lens carrier which is itself mounted for reciprocating motion in a film gate casting (10) by means of four leaf springs (31,35,41,45). The two outer springs (31 and 35) are centrally fixed to the casting (10) while the two inner springs (41 and 45) are centrally fixed to the lens carrier. The free ends of all four springs are fixed to spacers (51 and 52). The lens carrier includes a threaded bore (71) which receives a lead screw (72). A servo motor (76) is provided to rotate the lead screw (72) in both directions alternately.
