Abstract
An electrophotographic copying machine having an editorial function includes an original table formed on the top surface of a main unit, and an original is placed thereon while facing upward. A shaft is installed in the vicinity of one end of the top surface of the main unit, and this shaft supports rotatably an optical system for scanning the original so as to be able to contact with or part from the original table. A transparent tablet is placed between the original and the optical system, and this table works in cooperation with a write pen. After placing the original, an operator puts the tablet thereon and operates the pen to specify the position of the original intended to be edited. Responsively, the positional data thereof is outputted from the tablet. In a trimming mode or a masking mode, LEDs constituting a partial eraser are lighted in response to the positional data, and an electrostatic latent image on a photosensitive drum is modified. In a centering mode, paper feed timing is controlled in response to the positional data.
