Beschreibung
Zusammenfassung:	Scanning apparatus includes a linear array of sensors so that there is effectively a series of independent sensor elements disposed in aligned relation generally perpendicular to a scanning axis. Each sensor is arranged to provide a data output in response to a sensed code mark and an output channel is coupled to each sensor. Logic responsive to detection of a first code mark by a sensor of the array enables at least one code sensitive group of output channels and disables other output channels so that only a limited group of channels are rendered responsive to subsequently detected code marks.
