    • 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.
    • 一种静电复印设备,其中具有在其表面上具有光敏元件的旋转滚筒可旋转地并可拆卸地设置在壳体内的预定位置。 该装置具有一对沿着所述旋转滚筒的中心轴线方向彼此间隔开的内侧板,安装在每个所述板的内表面上的预定位置处的引导和支撑构件, 并且形成在每个所述引导和支撑构件中;轴承孔,其具有在基本上垂直于所述中心轴线方向的方向上开口的凹部;以及至少一个引导表面,所述至少一个引导表面沿所述轴承孔的所述凹部沿大致垂直于所述 中心轴线旋转。 当所述旋转磁鼓的两侧部分中的每一个的选定位置沿着每个所述引导表面移动时,所述旋转磁鼓的每个侧部通过每个所述凹部定位在每个所述轴承孔内,因此所述旋转磁鼓被安装 可旋转地和可拆卸地在基本上垂直于所述中心轴线方向的方向上。
