Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
167 words
A camera attachment for an electrophotographic copying machine having a housing including an upper surface with a generally horizontally disposed image entrance window and an exposing device within the housing behind the image entrance window, the attachment comprising: an upward extending arm releasably mountable upon the housing; an objective lens mounted upon the arm, having a freely accessible incident light receiving optical surface, and an optical axis which is generally parallel to the upper surface when the arm is mounted on the housing; a releasably mountable reflective surface, disposed at angles of about 45° to the axis of the objective and the upper surface of the housing; and wherein the objective, reflective surface, and entrance window are arranged, such that reflected light from a remote illuminated opaque object enters the freely accessible optical surface and is directed by the objective lens and the reflective surface to form an original two-dimensional image upon the entrance window detectable by the exposing device for reproduction by the electrophotographic copying machine.
Claim 2
Dependent Claim
167 words
A camera attachment for an electrophotographic copying machine having a housing including an upper surface with a generally horizontally disposed image entrance window and an exposing device within the housing behind the image entrance window, the attachment comprising: an upward extending arm releasably mountable upon the housing; an objective lens mounted upon the arm, having a freely accessible incident light receiving optical surface, and an optical axis which is generally parallel to the upper surface when the arm is mounted on the housing; a releasably mountable reflective surface, disposed at angles of about 45° to the axis of the objective and the upper surface of the housing; and wherein the objective, reflective surface, and entrance window are arranged, such that reflected light from a remote illuminated opaque object enters the freely accessible optical surface and is directed by the objective lens and the reflective surface to form an original two-dimensional image upon the entrance window detectable by the exposing device for reproduction by the electrophotographic copying machine.
Claim 3
Dependent Claim
168 words
An optical device for forming a reproducible visual image on an image entrance window for an exposing device of an electrophotographic copying machine, of an illuminated opaque object positioned externally and remote from the copying machine and optical device, wherein the image entrance window is positioned in a first plane and wherein the illuminated opaque object is positioned in a second plane which is oriented substantially perpendicular to the first plane, with the optical device including a camera objective adapted to form the visual image from reflected light incident upon an exposed optical surface of the camera objective, the camera objective directly transmitting the visual image of the opaque object to a reflective means positioned externally of the copying machine, the reflective means in turn directly transmitting the visual image onto the image entrance window of the exposing device, such that the visual image remains in visual form throughout formation of the reproducible visual image on the image entrance window of the exposing device of the Copying machine.
Claim 4
Dependent Claim
168 words
An optical device for forming a reproducible visual image on an image entrance window for an exposing device of an electrophotographic copying machine, of an illuminated opaque object positioned externally and remote from the copying machine and optical device, wherein the image entrance window is positioned in a first plane and wherein the illuminated opaque object is positioned in a second plane which is oriented substantially perpendicular to the first plane, with the optical device including a camera objective adapted to form the visual image from reflected light incident upon an exposed optical surface of the camera objective, the camera objective directly transmitting the visual image of the opaque object to a reflective means positioned externally of the copying machine, the reflective means in turn directly transmitting the visual image onto the image entrance window of the exposing device, such that the visual image remains in visual form throughout formation of the reproducible visual image on the image entrance window of the exposing device of the Copying machine.
