Abstract
Abstract A sequential reading code recognition system for recognizing the code on moving objects to regulate the movement of these objects as the codes thereon are recognized. Three scanners are employed for each station. The first scanner detects the presence of an object and enables the outputs of the other two code reading scanners to be received by the storage unit. The storage unit for the code recognition system for each station contains a preset code. When the code on the object corresponds to the preset code on a bit-by-bit basis an action initiating output is generated.
