Abstract
A data read device includes a read window, and a read section for optically reading a bar code on an article passing across a limited space in front of the window, and for generating output data corresponding to the bar code. The read device further includes a processing circuit for detecting that the article has passed across the limited space, from one side of the window to the other, and cancelling the output data generated from the read section, upon detection of this movement.
