ABSTRACT:
An electrostatic copying apparatus of the type in which a rotary drum having a photosensative member on its surface is rotatably and detachably disposed at a predetermined location within a housing. The apparatus has a pair of inner side plates spaced apart from each other in the direction of the central axial line of rotation of said rotary drum, a guide and support member mounted at a predetermined location on the inside surface of each of said said plates, and formed in each said guide and support member, a bearing hole having a recess opened in a direction substantially perpendicular to said central axial line of rotation and at least one guide surface extending from said recess of said bearing hole in a direction substantially perpendicular to said central axial line of rotation. When a selected site of each of both side portions of said rotary drum is moved along each said guide surface, each of said side portions of said rotary drum is positioned within each said bearing hole through each said recess and thus, said rotary drum is mounted rotatably and detachably in the direction substantially perpendicular to said central axial line of rotation.
