To reduce the size, the weight, and the production cost and to improve the reliability of an optical device for a code reader for reading a code (24) imprinted on the package of an article, a light emitting element (21), a prism (22) and a light receiving element (15) are all fixed to a semiconductor substrate (14), so that the assembly at the semiconductor chip level of these elements (15, 21 and 22) is possible. This device can be used for an optical apparatus for reading various codes used in POS systems, physical distribution/management systems, production control systems, and so forth.

Afin de réduire la taille, le poids et les coûts de production d'un dispositif optique destiné à un lecteur de code servant à lire un code (24) imprimé sur l'emballage d'un article et afin d'améliorer la fiabilité de ce dispositif, on fixe ensemble sur un substrat à semi-conducteur (14) un élément photoémetteur (21), un prisme (22) et un élément photorécepteur (15), de sorte que l'assemblage de ces trois éléments (15, 21 et 22) au niveau de la puce semi-conductrice soit possible. Ledit dispositif peut être utilisé pour un appareil optique servant à lire divers codes utilisés notamment dans des systèmes au point de vente, dans des systèmes de distribution/gestion physique et dans des systèmes de commande de production.
