摘要: A bar code reader missing link detection system for of missing, defective or misaligned chain links in assembled in-process chains includes a light source illuminating one more chain, sensitive diode array detecting an image fixed scan line, produced by the source, and lens focusing incoming onto array, wherein is arranged such that reflects from continuously scanned, digitized, data obtained thereby interpreted to detect links.
