Abstract

A collective objects management system for objects such as documents contained in file folders in drawers of file cabinets. Each file folder has an electrical circuit with a visible indicator mounted on the file folder. Each folder circuit has an address decoder with a unique system address which generates a VALID signal whenever an incoming address from a source is a match. A local microcomputer and optional encoder receive incoming object identification signals from the source and supplies the desired object address to all the file folders in the cabinet. To aid the user, each file drawer has a visible indicator mounted on the front panel, the panel indicator being illuminated when the sought folder is contained in that drawer. The invention can be applied to a wide variety of collective objects management systems, such as supermarkets, automobile parts distributors, and various manufacturing operations.
