Abstract

See full text

In a barcode reader, a sensor controller sets time of one frame of a line image sensor based on output time necessary for data output of one frame from the line image sensor and lighting time of an LED. A light source controller performs first lighting control to turn on the LED only for the lighting time after termination of the data output within the time of one frame, and second lighting control to turn on the LED only for the lighting time so as to include the entire period of the data output within the time of one frame.
