ABSTRACT:
A magnification changing device in an imaging optical system comprises a magnification changing lens system including first and second lens groups disposed in series on the optic axis of the imaging optical system, a cylindrical cam member rotatable about a rotational axis extending along the optic axis and having first and second cam grooves spirally formed in the circumference thereof, the first cam groove being formed through the peripheral wall of the cylindrical cam member, a cylindrical movable member coupled to the first lens group, the movable member being fitted to the outer periphery of the cylindrical cam member and coupled to the second cam groove to be slid in the direction of the rotational axis while the cylindrical cam member rotates, the peripheral wall of the cylinder of the movable member being partly cut away by a groove extending along the rotational axis from one end opposed to the second lens group, a bar member fitted to the inner periphery of the cylindrical cam member, and a coupling member coupling the second lens group to the bar member through the first cam groove and slidable in the direction of the rotational axis together with the bar member and the first lens group while the cylindrical cam member rotates, the coupling member being provided so as to fit into the groove of the movable member when the first and second lens groups approach each other.
