Electrophotographic copying machine having editorial function

摘要

An electrophotographic copying machine includes a mouse connected to a main unit to input positional information for editing. When the mouse is moved on an original for editing, pulses are generated from the mouse according to a rotation of a roller, which are counted by a counter of a microcomputer. A count value of the counter is utilized as positional data. In order to display a copy quantity, there is provided a segmental display. In the editing mode, a predetermined segment of the segmental display is selectively lightened so as to display the states of sequential position designations by the mouse. Therefore, it is possible to visibly confirm the state of the position designations for editing.
