Document sorter system having interchangeable pocket modules

摘要

A document sorting system includes a concatenation of document receiving modules, each module having a plurality of pockets and being distinguishable from another module only by its position in the concatenation. A coding circuit is included in each module to generate a unique identifying code for each of the plurality of pockets in the module. The identifying code has a first binary portion based on the position of the module in the concatenation, and a second portion based on the position of the pocket in the module.
