Abstract
In the data processing circuit of a decoder box, the position sensing circuit senses the position of the bar-code symbol imaged by a video camera in the imaging area of the video camera on the basis of the output of the frame memory. Then, the shift direction judging section of the data processing circuit determines the direction in which the bar-code symbol imaged by the video camera is shifted with respect to the imaging area of the video camera on the basis of the output of the position sensing section. The display control section of the data processing circuit displays the position of the bar-code symbol on a label position indicator provided on the decoder box on the basis of the judgment result of the shift direction judging section.
