Abstract
A handy scanner removably held by a scanner holder is composed of an LED unit for illuminating a bar code affixed to an article, a light-receiving unit for producing an output signal corresponding to reflected light from the bar code, and a processing section for obtaining bar code information from the output signal produced by the light-receiving unit. Particularly, the processing section includes a comparator for determining whether the handy scanner is held by the holder, and a control circuit for turning on the LED unit when it is detected by the comparator that the handy scanner is removed from the scanner holder and turning off the LED unit when the bar code information has not been obtained within a predetermined time after turning on the LED unit.
