A hand-held dual reading head including a hand-held housing having a light transmissive window at one end thereof; and containing an actuatable bar-code reader, which produces a light beam which exits the housing via the window and detects light from the beam reflected from a bar code tag to generate a first electrical signal corresponding to bar code data read from the tag. The housing also contains an actuatable radio frequency tag reader which includes a transmit/receive coil mounted adjacent the one end of the housing containing the window, for producing a radio frequency signal of a first frequency to energize a radio frequency transponder-type identification tag and for receiving an identifying signal of a second frequency transmitted by an energized radio frequency identification tag to provide a second electrical output signal corresponding to the tag identifying signal, preferably in the same signal format as the bar-code data. The reading head has a common signal output connected to receive the first and second electrical signals, and a manually actuatable switch arrangement mounted on the housing for selectively actuating one of the bar-code tag reader and the radio frequency tag reader depending on the type tag to be read. Preferably, the housing is gun-shaped and the switch arrangement is a trigger-like normally OFF switch with two ON positions, one for each of the readers.
A hand-held dual code reading head comprising: a hand-held housing having a light transmissive window at one end thereof; an actuatable bar code reader disposed in said housing and including a light source for producing a beam of light directed along a path to exit said housing via said window towar
A hand-held dual code reading head comprising: a hand-held housing having a light transmissive window at one end thereof; an actuatable bar code reader disposed in said housing and including a light source for producing a beam of light directed along a path to exit said housing via said window toward a bar-code tag, scanning means for scanning said light beam along a scan line across the bar code tag and a light sensor for detecting the intensity of light from said light beam reflected from a bar code and for producing an electrical signal corresponding thereto; an actuatable radio frequency tag reader for producing a radio frequency signal of a first frequency for energizing a radio frequency identification tag and for detecting a radio frequency identifying signal of a second frequency produced by an energized tag and producing a corresponding output signal, said tag reader being disposed in said housing and including a coil which is mounted within the housing at said one end of said housing so as to avoid said light path and circuit means connected to said coil for producing said corresponding output signal; and, and means, which are manually actuatable by a user of said reading head, for selectively actuating one of said bar code reader and said radio frequency tag reader.
