摘要

A shell-type electrostatic copying apparatus comprising a lower supporting frame, an upper supporting frame mounted on the lower supporting frame for free pivotal movement between an open position and a closed position, and a unit which includes a unit frame and a rotating drum mounted rotatably on the unit frame and adapted to be detachably mounted on the upper supporting frame. A provisional unit placing means is provided in the lower supporting frame for supporting the unit frame movably. The unit is mounted detachably on the upper supporting frame by placing the unit on the provisional unit placing means, pivoting the upper supporting frame from the open position to the closed position and then moving the unit in a specified direction.
