Abstract

PURPOSE:To select an arbitrary reduced magnification without disturbing registration by providing a cam mechanism for displacing a lens construction in the direction rectangular to the lens moving direction at the time of moving the lens for changing over the magnification. CONSTITUTION:A barlike cam 4 is mounted to a fixing member in order to maintain an angle theta to the optical axis A. The cam 4 is a 3-stage cam formed with a small-diameter part 4a in the central part, a middle-diameter part 4b in the left side part, and a large-diameter part 4c in the right side part, respectively. One end part of springs 5 is held detained to the large-diameter part 4b of the cam 4, and the other end part of the springs 5 is detained to a guide shaft 7. The guide shaft 7 is held pulled to the cam 4 side by these springs 5, and the V-pulley 3 provided to a lens mount 2 abuts on the cam 4, and these constitute a cam mechanism 25. By this constitution, arbitrary reduced magnifications are selected without disturbing registration.
