ABSTRACT:
In a copying apparatus, a mode change-over mirror is selectively displaced between its retracted position and its operative position, whereby the copying mode is selectively changed over to a first mode and a second mode. The operative position is set at at least two places. When the mode change-over mirror lies at a first operative position, second mode copying at a first magnification is effected and when the mode change-over mirror lies at a second operative position, second mode copying at a second magnification is effected.
