Abstract
A lens frame radially-displacing mechanism of a retractable photographic lens, includes a photographing optical system; a linearly advancing/retreating ring guided linearly in an optical axis direction; a radially-displaceable support frame pivoted parallel to the optical axis, supports a radially-displaceable optical element and rotates between an on-axis position and an off-axis displaced position when the retractable photographic lens moves between the ready-to-photograph state and the retracted state; a rear support frame supporting a rear optical element; and a distance controller which controls approaching positions of the displaceable support frame and the rear support frame. The distance controller includes an approaching-position limiter which limits movements of the displaceable support frame and the rear support frame to a predetermined distance when the displaceable support frame moves rearward, and a distance extender which extends the predetermined distance when the displaceable support frame rotates toward the off-axis displaced position.
