Abstract:
1. An automatic bar code symbol reading system, comprising: a housing having a light transmission aperture through which light of at least one wavelength can exit and enter into the housing; a bar code presence detection mechanism in the housing, for detecting a presence of a bar code located in a scan field defined external to the housing, and for automatically generating an activation signal in response to the detection of the presence of the bar code located in the scan field; an activatable scan data producing mechanism in the housing, for producing scan data from a bar code located in the scan field, the scan data producing mechanism including: an activatable scan data processing mechanism for processing produced scan data so as to detect and decode a bar code symbol in the scan field, and for automatically producing symbol character data representative of the decoded bar code symbol; and a control mechanism for controlling the operation of the automatic bar code symbol reading system, the control mechanism including:
