Abstract

Abstract An improved high resolution scanner for use in a conventional scanner housing. A light receiving guide transversely moves a conventional lens and CCD for scanning portions of an object to be scanned. The resulting scanned portions, when combined, produce a high resolution image of the scanned image.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 297 words
A high resolution scanner assembly for use in a scanner housing having a pair of rails longitudinally mounted along opposite sides of the housing and a seat stepper motor and drive belt assembly mounted proximate to one of the rails, said scanner assembly comprising: a light-receiving device including a light receiving seat movably connected to said rails and rigidly connected to said drive belt assembly for moving along said rails in response to said drive motor actuating said drive belt assembly; said light-receiving device includes a pair of guide rails mounted transverse to said scanner rails, a guide driver located along said guide rails, a light receiving guide movably mounted on said guides rails and connected to said guide driver for movably positioning said guide along said seat and a plurality of mirrors for directing an illuminance of an object upon said light receiving guide; said light-receiving guide includes an electro-optic transducer having a field of view for transmitting an electrical signal representative of the illuminance from an object in the field of view and a zoom lens for adjusting the width of the field of view of said transducer housed in an enclosed housing within said guide for receiving the illuminance of an object from said mirrors through said lens onto said transducer; a CPU mounted within said housing and electrically connect to said transducer, said lens, said device driver and said guide driver; a control program executed by said CPU for sequentially scanning at least a first select portion of said object and at least a second portion of said object, whereby said scanner assembly is operated by said control program to scans select portions of said object which when combined by said CPU provide a high resolution image of said object to be scanned.
