摘要 |
An optical-information-reading apparatus includes an imaging optical system having a varifocal lens that adjusts a focal position, a solid-state image sensing device that images a code symbol, a ranging laser that measures a distance to the code symbol, and a decoder that calculates the distance to the code symbol using the ranging laser. The apparatus controls the varifocal lens based on calculated distance information. |
