Abstract
A plurality of electrostatic copying machines (12), (13), (14), (16) are interconnected by bus lines (19), (21), (22). Each copying machine (12), (13), (14), (16) is provided with a sensor unit (23) for sensing various status parameters of the copying machine (12), (13), (14), (16) such as whether the copying machine (12), (13), (14), (16) is available for use, the copy sheet size, the number of copies made, the number of copy sheets remaining, etc. Each copying machine (12), (13), (14), (16) is further provided with a display unit (17) for displaying the status parameters of all of the copying machines (12), (13), (14), (16). A microcomputer (31) is provided at one of the copying machines (12) for storing and processing the status parameters and producing a hard copy.
