Abstract

The invention relates to the line-by-line optical scanning of documents and images by means of a sensor. According to the invention, to this end a reference point of the optical axis is displaced along a v-shaped trajectory, whereby the distance from the sensor to the document remains the same. This allows for a very simple mechanical structure for the optical support, which can be part of an articulated quadrangle.
