Abstract
A document scanner comprises a first image sensor unit () and a second image sensor unit () and a scanning mechanism () for causing relative movement between a document and the units so that the units scan the document in a scanning direction. The first unit () is situated ahead of the second unit () in the scanning direction and partially overlaps the second unit. Each sensor unit has a respective linear array () of electromagnetic radiation detectors and one or more light guides () for directing light from a respective one of two imaging lines () on to the detectors, wherein, in use, the imaging lines scan the document to capture data representative of two respective sets of scan line portions for combination to obtain a succession of scan lines for the document, the one or more light guides of the first unit () are angled rearwardly with respect to the scanning direction, whilst the one or more light guides of the second unit () are angled forwardly with respect to the scanning direction, so as to reduce the distance with respect to the scanning direction, between the imaging lines ().
