Improvements in and relating to document scanners.

摘要

A document scanner is described in which a book can be offered up to a wedge-shaped housing containing at least one window through which one page of the book can be viewed.

The book is carried by a trough shaped support which is movable up and down as required and may be fully floating to allow different thicknesses etc. of book to be accommodated.

The book support is itself rotatable about a vertical axis to an opposite page of a book to be presented to the window.

A lamp is incorporated in the housing off-axis to illuminate the page to be scanned theough the viewing corridor.

The scanning element is typically an elongate array of photosensitive junctions and scanning is achieved by electrically addressing each of the junctions in succession.
