Abstract
Abstract A high resolution scanner apparatus has a disc upon which is mounted an original to be scanned. The disc may include a track for providing high accuracy tracing of the original. If the original is transparent, such as a photographic film, the disc may include a transparent first disc upon which the original is mounted and a second disc upon which a spiral track is provided, the first and second discs being mounted coaxially to rotate together. The discs may be compact or laser discs. A slide structure has at least a first arm for reading the original. The slide structure may include a second arm for tracing the track when included. The second arm may also include a light source for illuminating the original through the transparent first disc. The slide structure moves radially with respect to the discs, either using a precision controller or according to the tracing of the track by the second arm. If the original is not transparent, such as a printed original or a photographic film on a white sheet, a single disc may be used with the original mounted on one side and the optional track being on the other side. Then the first arm provides a light source for illuminating the original for reading using reflected light. The track may store bit clock information to allow a control circuit to rotate the disc(s) at a constant linear velocity.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
122 words
A scanner apparatus comprising: rotatable means having a first surface for mounting an original to be scanned and a second surface having a track; means for rotating the rotatable mounting means; a structure comprising a first arm disposed for reading the original on the first surface and a second arm disposed for accurately tracing the track on the second surface; means for moving the structure radially with respect to the rotatable mounting means; and means for controlling the rotating and moving means so that the first arm reads the original, the controlling means comprising means for regulating the rotating and moving means according to an output from the second arm so that the first arm reads the original at a high resolution.
Claim 2
Dependent Claim
122 words
