Abstract

Traditional photocopiers have a plate glass window positioned at some distance from the edge of the photocopier itself. When one wishes to photocopy an image or material from a book that is close to the center of the book, the binding of the book has a tendency of preventing the pages from laying flat on the photocopier window so that the resulting photocopying is distorted or blurred.

Photocopier Plate That Can Be Raised to Copy Thick Books

      Traditional photocopiers have a plate glass window positioned
at some distance from the edge of the photocopier itself.  When one
wishes to photocopy an image or material from a book that is close to
the center of the book, the binding of the book has a tendency of
preventing the pages from laying flat on the photocopier window so
that the resulting photocopying is distorted or blurred.

      One solution to this problem is to provide a plate glass window
that can move upwards from the surface of the photocopier so that a
book opened at approximately 90 degrees angle could be placed with
one
leaf on the window with the center joint of the inside of the book
placed against an edge of the window so that the page being copied
can lie flat on the window.  The remainder of the book associated
with
the other leaf not being copied can hang down as will be appreciated.

      The mechanism for raising the plate glass window will not be
described, as it will be obvious to persons skilled in the art.
Sidewalls, sealing light from entering can be provided by means of
bellows or other vertically extendable means such as extendable
walls.  The focusing or lens mechanism of the photocopier would be
keyed to the position of the window to adjust to the new distance so
that the original would be brought into focus for copying.  After the
book is copied the window could be lowered back into its original
position...
