Abstract
An optical code symbol reading system including a hand-supportable housing having a light transmission aperture. A manually-actuated trigger switch is integrated within the housing. An optical code symbol reading subsystem is disposed in the housing for optically reading a code symbol in the field external to the light transmission aperture, and generating symbol character data representative of the read code symbol. One or more light emitting diodes (LEDs) are disposed in the housing, for producing a visible illumination. Also, an optical-waveguide structure is disposed in the housing for coupling visible illumination produced from the one or more LEDs, so as to illuminate the region about the manually-actuated trigger switch, thereby causing the optically-translucent region about the manually-actuated trigger switch to glow and visually indicate where it is located on the hand-supportable housing.
