Abstract
Abstract The invention relates to an opto-electronic scanning apparatus with a document support on a common frame, and a scanning head scanning a document in two different directions, which is characterized in that on the frame a first carrier (4; 27) is mounted that can be driven by a first driving means (5; 18) in the first direction, that on the first carrier (4; 27) a second carrier (12) is mounted which carries a scanning head (16, 17) operating in the second scanning direction only, that the scanning head (16, 17) on the second carrier (12) is linearly movable in the second scanning direction only, and that for each direction of movement a separate driving means is provided.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
60 words
Opto-electronic image scanning apparatus comprising, a record carrier for retaining the image to be scanned, a plate, means for rotating said plate in a plane parallel to said record carrier, and a photosensitive scanning element positioned on said plate in a radial orientation relative to the axis of rotation of said plate whereby the image is scanned by said element.
Claim 2
Dependent Claim
60 words
Opto-electronic image scanning apparatus comprising, a record carrier for retaining the image to be scanned, a plate, means for rotating said plate in a plane parallel to said record carrier, and a photosensitive scanning element positioned on said plate in a radial orientation relative to the axis of rotation of said plate whereby the image is scanned by said element.
Claim 3
Dependent Claim
19 words
Apparatus in accordance with claim 1 which includes means for radially moving said photosensitive scanning element on said plate.
Claim 4
Dependent Claim
20 words
Scanning apparatus as claimed in claim 1, characterized in that the photosensitive scanning elements comprises at least one photodiode array.
Claim 5
Dependent Claim
27 words
Scanning apparatus as claimed in claim 3, characterized in that the photodiode array of the photosensitive scanning element covers the full extent of the second scanning direction.
Claim 6
Dependent Claim
37 words
Scanning apparatus as claimed in claim 3, characterized in that the photosensitive scanning element comprises a light source whose beam impinges almost perpendicularly on the document support, and that the reflected radiation impinges on the photodiode arrangement.
