Abstract
Abstract An apparatus for copying a document in which an operation unit is provided separately from a copying unit. The operation unit includes a memory to store the digital image signals inputted from the copying unit, a display to display the digital image on a screen, and an operation board to convert the display image into a desired image. The copy unit makes a copy image corresponding to the desired image on a recording material.
