Abstract: A multiple-input, mixed-type bar code processor, comprising: a plurality of retriggerable pulse generators, each having data inputs coupled to sources of potential representing fixed logic levels and each having at least one of a clear and a reset input coupled to a different one of a plurality of sources of input bar code data streams, for regenerating the input bar code data streams responsive to logic level transitions of the input bar code data streams, both when any input bar code data stream is logically low absent scanned data and when any other input bar code data stream is logically high absent the scanned data; a circuit for receiving all of the regenerated bar code data streams and generating a single output bar code data stream; and, a bar code data stream decoder coupled for receiving the single output bar code data stream.
