Abstract
An inventory locating device including an optical scanner for reading bar code labels containing product identifying information. A pair of measuring wheels, one positioned on each side of the scanner, is provided for running along a supporting surface as the optical scanner reads bar code labels on the surface. By means of an endless belt, rotational motion of the measuring wheels is transmitted to a shaft encoder permitting the distance traveled by the device to a given label to be calculated and tracked. Information gathered by the optical scanner and shaft encoder is relayed by a radio frequency transmitter to a remote receiver for storage and processing.
