Abstract:
A user-mounted reader for electro-optically reading bar code symbols located within a range of working distances remote from the reader, comprising:a) a light source in the reader for projecting a light beam through a window exteriorly of the reader to a symbol for reflection therefrom; b) a sensor in the reader and having a field of view, and operative for detecting light reflected off the symbol and passing through the window, and for generating an electrical signal indicative of the symbol; c) an activatable scanner in the reader for automatically and repetitively scanning at least one of the light beam and the field of view through the window across the symbol; d) a detector in the reader for detecting when the symbol is located within the range of working distances, and for activating the scanner to initiate the automatic and repetitive scanning across the symbol upon such detection; e) a signal processor in the reader, for processing and storing the electrical signal; f) a battery in the reader, for supplying electrical power to the source, sensor, scanner, detector and processor; g) a wrist strap located entirely rearwardly of the window, and operative for mounting the reader on a wrist adjacent a hand of a user at a position in which the window is elevated above the wrist and out of contact with the symbol during reading to allow the light beam and the reflected light to pass over a back of the hand of the user without obstruction from the strap; and h) a clip for mounting the reader remote from the wrist.
