ABSTRACT:
A support mount for the rotary drum of an electrostatic copying apparatus. A pair of guide and support members is positioned within the copier housing, spaced from each other a predetermined distance in the direction of the central axis of the drum. Each guide and support member has a shaft support opening with a recess extending substantially perpendicular to the drum axis and a main guide surface extending from the lower end of the recess away from the shaft support opening and substantially perpendicular to the drum axis. When the peripheral surfaces of the drum bearing members are moved along the main guide surfaces, each bearing member passes through the respective recess and is positioned within the respective support opening. A pair of projecting pieces are positioned at the side plates of a frame of the copying apparatus developing device. After positioning of the drum bearing member in the shaft support opening, the free ends of the projecting pieces abut the peripheral surface of the bearing members to fix the frame within the house.
