Abstract:
1. A symbol reading system, comprising: an input/output subsystem for transmitting signals to a host computer; a horizontal housing; a laser scanning subsystem for reading symbols within a volume above the horizontal housing; an imaging subsystem for reading symbols within the volume; a scale for measuring the weight of an object within the volume and transmitting a signal corresponding to the measured weight to the input/output subsystem; and a detection subsystem for projecting a pair of detection beams substantially normal to horizontal housing at the edge of the volume to detect objects in at least one of the detection beams, said detection subsystem comprising at least one photo-receiver positioned within said horizontal housing in alignment with an edge of the volume to receive return light reflected by an object in one of said detection beams and, wherein, in response to the detection of an object, the detection subsystem transmits a signal to the input/output subsystem.
