Abstract: Apparatus for automatically feeding sheet material such as fan fold paper to a photocopier in which the apparatus may be movable towards and away from the window of the photocopier either by disconnecting the apparatus completely from the photocopier by means of readily releasable clamps or by pivoting part of the apparatus away from the window of the photocopier whereby the apparatus may be used not only to photocopy fan fold paper but used in a conventional manner to photocopy normal documents. Control signals to operate the apparatus are derived by a light sensitive means viewing the light source within the photocopier through the window of the photocopier.
