Abstract

Jacquard cards are produced from a coloured drawing on plain or squared paper by a scanner comprising a lens focussed on successive elementary areas, a prism dispersing the light passing through the lens to form a spectrum, and at least one photocell positioned to receive a predetermined colour. Preferably a plurality of cells are provided so that the whole pattern is produced during a single scan. Compound colours which make two or more cells respond may be used, a code converter being provided to translate the cell outputs into punch actuating signals. Threshold circuits are provided to suppress spurious responses of the cells caused by subsidiary peaks in the reflectance spectrum of the dyes used for the drawing.
