Abstract
Abstract A scanning device is herein disclosed for focusing a flowing light image of a stationary original upon a moving imageretaining member. The scanning components involved are positively driven through a single drive means and the motion imparted thereto synchronized with the moving image-retaining member by a control means.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
209 words
Apparatus for scanning a viewing plane and for focusing a light image of an original stationarily supported therein upon a moving image-retaining member including a lens element arranged to move freely over a path of travel parallel to the viewing plane and to focus light images of an original supported thereon onto the moving image-retaining member, illuminating means interposed between said lens element and the viewing plane being adapted to illuminate an incremental region in said viewing plane, said illuminating means being arranged to move freely along a path of travel parallel to said viewing plane whereby successive incremental regions thereon are illuminated, a moveable arm secured to both said lens element and to said illuminating means being arranged to drive said lens element and said illuminating means along their respective paths of travel through a scanning path whereby each successive region illuminated in said viewing plane is focused by the lens on the moving image-retaining member, control means operatively associated with said connecting means and the moving image-retaining element to synchronize the motion of the lens and the illuminating means with that of the moving image-retaining member whereby successive incremental regions of illumination in the viewing plane are focused upon the moving image-retaining member in a nondistorted manner.
Claim 2
Dependent Claim
209 words
Apparatus for scanning a viewing plane and for focusing a light image of an original stationarily supported therein upon a moving image-retaining member including a lens element arranged to move freely over a path of travel parallel to the viewing plane and to focus light images of an original supported thereon onto the moving image-retaining member, illuminating means interposed between said lens element and the viewing plane being adapted to illuminate an incremental region in said viewing plane, said illuminating means being arranged to move freely along a path of travel parallel to said viewing plane whereby successive incremental regions thereon are illuminated, a moveable arm secured to both said lens element and to said illuminating means being arranged to drive said lens element and said illuminating means along their respective paths of travel through a scanning path whereby each successive region illuminated in said viewing plane is focused by the lens on the moving image-retaining member, control means operatively associated with said connecting means and the moving image-retaining element to synchronize the motion of the lens and the illuminating means with that of the moving image-retaining member whereby successive incremental regions of illumination in the viewing plane are focused upon the moving image-retaining member in a nondistorted manner.
Claim 3
Dependent Claim
34 words
The apparatus of claim 1 wherein said movable arm is pivotally retained at one end about the imaging plane and having slidably connected to the arm therein said lens element and said illuminating means.
Claim 4
Dependent Claim
50 words
The apparatus of claim 2 wherein said control means comprises a cam member having a working profile in operative communication with said arm and being arranged to translate a motion to said arm whereby said lens and said illumination means are scanned across said viewing plane at a constant velocity.
Claim 5
Dependent Claim
40 words
The apparatus of claim 3 wherein said cam is further arranged to restore said lens element and said illuminating means to a start of scan position after completion of the scanning pass at a velocity greater than the scanning velocity.
