摘要
The backward reflecting optical scanning system operates on the multiple-X principle. It can be used in sales point applications, where the articles are fitted with coded labels and automatically scanned at a station. The scanning tracks consists of a number of parallel lineS. Adjacent tracks are excited in accordance with the speed of a rotating element. The reflecting medium is formed by ten reflecting mirrors (141-145, a, b) arranged around the shaft of the rotating element.
