Abstract
A beam scanning-type information readout device, and more particularly, a hand-carried beam scanning-type information readout device which can read information consisting of a bar-code-symbol applied to a product and which is low in cost, simply operated and very useful and has high readout accuracy. The beam scan type information readout device comprises a laser beam generator, an optical beam scanner which deflects and scans plural beams generated from the laser beam generator or deflects and scans a beam generated from the laser beam generator in plural directions, an optical beam detector which detects the beam reflected from the bar-code-symbol, and a case which functionally and physically accommodates the above-identified elements and also provides a grip portion for the operator.
