Abstract

1. A light source for scanning a document line-by-line, constituted by a flash tube presenting an inner channel, the ends of which are connected respectively to two gas storage chambers in which are disposed two operating electrodes respectively of the tube, said tube being equipped on the outside with a priming electrode disposed between the two operating electrodes, characterized in that said inner channel is a capillary channel (10) over the useful length of said tube (1) destined to face the document, and that, over the useful length, said tube is a thick-walled tube, the section of which is, for a portion (16) facing the document, substantially formed as a V with a rounded angle in order to form a magnifying glass built into the wall of the tube.
