Abstract: A system and method for automatically storing bar coded elements such as containers for electronic components in storage bins such as drawers in a cabinet and for providing access to only the drawer containing a desired element substantially eliminates human error and increases reliability in the handling and processing of these elements and reduces the cost of inventory management and control. The storage and retrieval system includes a bar code reader coupled to a controller which, in turn, is coupled to a plurality of storage cabinets. Each storage cabinet includes a plurality of drawers each coupled to the controller via the combination of an electrical interface and a mechanical drive. Reading of the bar code on an element or on an apparatus into which the elements are deposited for processing or installation into the controller automatically opens a drawer associated with that particular component.

Abstract: An electronic component matching system operates in conjunction with a component transport arrangement wherein a component-carrying supply tape from which components are removed for positioning upon a circuit board in a matched manner is linearly displaced. The components are thus sequentially moved to a pick-up point whereupon a predetermined number N of components having similar operating characteristics are incorporated in the same circuit. As the component-carrying supply tape is displaced toward the component pick-up point, an electro-optical sensor detects the presence or absence of components on the supply tape and provides this information to a microcomputer controller.
