US 4,379,631 A · Apparatus having a copier function and a printer function

Abstract

This specification discloses an apparatus having both the copier function of optically exposing the surface of a photosensitive member to an original image and the printer function of converting an electrical information signal into light and exposing the surface of the photosensitive member to such light. The apparatus has a switching device for switching on and off the exposure of the surface of the photosensitive member by the copier function and the printer function, and a timing device governing the ON-OFF switching by the switching device. Thereby, the exposure of the surface of the photosensitive member by the copier function and the printer function can be switched on and off at necessary timed intervals to form an image.

Dependent claims

An apparatus for recording on a recording medium with a beam carrying information, said apparatus comprising:

an original table having a transparent plate providing a surface on which an original may be placed;
means defining a first optical path extending between said original table and the recording medium;
means for producing a high energy beam carrying information;
means defining a second optical path extending between said beam producing means and the recording medium;
and
means, provided across said first optical path, for blocking the high energy beam produced by said producing means from being projected to said original table.
