BARCODE IMAGING WORKSTATION HAVING SEQUENTIALLY ACTIVATED OBJECT SENSORS

摘要

A workstation includes a proximity system having multiple object sensors each associated with an object field of view for detecting a target object outside the housing. Each object sensor includes an IR emitter for emitting IR light into an IR emission field and an IR sensor for sensing returned IR light within an IR detection field that intersects the IR emission field. The workstation also includes a controller is operatively connected to the proximity system for activating each one of the multiple object sensors sequentially.

1. An apparatus comprising:
a housing having a first window in an upright plane and a second window in a generally horizontal plane that intersects the upright plane; an imaging sensor within the housing and having an array of photosensitive elements; a proximity system including multiple object sensors each associated with an object field of view for detecting a target object outside the housing, wherein each object sensor includes an infrared (IR) emitter for emitting IR light into an IR emission field and an IR sensor for sensing returned IR light within an IR detection field that intersects the IR emission field; an illumination system supported by the housing and operative for illuminating the target object with illumination light; and a controller operatively connected to the imaging sensor, the illumination system and the proximity system, for energizing the illumination system in response to detection of the target object in one of the object field of view associated with the multiple object sensors and processing the illumination light returned from the target object and being captured in a field of view associated with the imaging sensor, and operative for activating each one of the multiple object sensors sequentially wherein activating an object sensor comprises activating the IR emitter in the activated object sensor and detecting returned IR light caused by the IR emitter with the IR sensor in the activated object sensor.
