A device for optically scanning a document (5), the device comprising at least two linear opto-electronic transducers (137, 139; 157, 159, 161), an optical system (141, 143; 163, 165, 167) adapted to image a narrow elongate part (145, 169) of the document on the transducers and a movable part (7, 45) by means of which the imaged part of the document can be displaced at right angles to its longitudinal direction in order to scan the desired part of the document, characterized in that the imaged part (145, 169) of the document (5) comprises N narrow strips (147, 1 1 E9 ; 171, 173, 175) which are contiguous in longitudinal direction, N representing an integer larger than unity, in that the device comprises N linear opto-electronic transducers (137, 139; 157, 159, 161) which are substantially aligned with a space (155, 183, 185) between adjacent transducers, in that the optical system comprises N imaging systems (141, 143; 163, 165, 167), associated one each with the transducers, and in that adjustment means are provided for displacing each transducer with respect to the associated imaging system.

A device for optically scanning a document (5), the device comprising at least two linear opto-electronic transducers (137, 139; 157, 159, 161), an optical system (141, 143; 163, 165, 167) adapted to image a narrow elongate part (145, 169) of the document on the transducers and a movable part (7, 45) by means of which the imaged part of the document can be displaced at right angles to its longitudinal direction in order to scan the desired part of the document, characterized in that the imaged part (145, 169) of the document (5) comprises N narrow strips (147, 1 1 E9 ; 171, 173, 175) which are contiguous in longitudinal direction, N representing an integer larger than unity, in that the device comprises N linear opto-electronic transducers (137, 139; 157, 159, 161) which are substantially aligned with a space (155, 183, 185) between adjacent transducers, in that the optical system comprises N imaging systems (141, 143; 163, 165, 167), associated one each with the transducers, and in that adjustment means are provided for displacing each transducer with respect to the associated imaging system.
Claim 3
Dependent Claim
88 words
A device as claimed in Claim 1, characterized in that the adjustment means are designed to perform translations of the transducer (65) with respect to the imaging system (107) along the optical axis (109) of the imaging system and in two directions at right angles to this optical axis (translations 111, 103, 81) as well as rotations of the transducer about the optical axis and about an axis (115) at right angles to the optical axis and to the longitudinal direction of the transducer (rotations 133 and 123).
