Abstract
A variable magnification apparatus is provided with a magnification converting mechanism and a scan speed change mechanism. In the magnification converting mechanism, the force generated by operating a magnification converting lever is transmitted to the lens holder through a magnification change-over arm and to a speed change selection member through a scan speed change shaft. In the scan speed change mechanism, the number of rotations of an output shaft is changed by a selected rotation transmission member which is actuated by a speed change ratio selection member.
