ABSTRACT:
Optical scanning device having N linear opto-electronic transducers (157, 159, 161) which are substantially aligned with spaces (183, 185) between adjacent transducers. With each transducer (157, 159, 161) is associated an individual imaging system (163, 165, 167) for imaging a narrow strip (171, 173, 175) of the document on the transducer. Each transducer (157, 159, 161) is displaceable with the aid of adjustment means with respect to the associated imaging system (163, 165, 167). As a result the transducers can be adjusted so that the narrow strips (171, 173, 175) adjoin each other and are aligned. Together they cover a narrow elongate part (169) of the document. In this manner, a comparatively large document can be scanned with a high resolving power by means of comparatively simple and hence inexpensive transducers and imaging systems.
