Article sorting system - uses multi-binary code marking and reader devices to control destination of article

摘要

A sorting device for articles having a machine readable differential marking e.g. some form of code marking, has electro-optical devices to read the various coded markings and produce control signals which operate the transport paths for the various articles to allow them to reach destinations appropriate to their code markings, has the code marking consisting of several binary figures and the articles to be sorted passed in front of a series of one or more reading devices. These devices produce signals etc., interpreted by other reactions of the machine which ensure that all coded articles arrive in their specified storage area.
