Optical code reader having an illumination light source emitting light for at least a preset period responsive to operation of a trigger switch

摘要: An optical code reader includes a reading window, control circuit for sensing an image of 2-dimensional via the window and converting sensed into data, portable frame having opening used as accommodating circuit. In reader, trigger switch issuing instruction with set within preset distance from code, illumination light source applying period after is issued by switch, section based on reflected obtained when illuminated source, controller elongating activation continuously longer than period.
