An inventory management system using an automated guided vehicle that moves back and forth along a guideline and that scans articles on shelves is introduced. The inventory management system may comprise: a scanning unit for recognising information about articles stacked on shelves; a guideline following a plurality of spaced apart shelves; a vehicle for supporting the scanning unit and for moving along the guideline by recognising the guideline; and a control unit for controlling the vehicle such that the vehicle can move along the guideline that is recognised using a line recognition part.

A transmission optical system comprises a concave surface mirror whose reflection surface is directed toward a deflection mirror surface and a transmission lens which is disposed between the concave surface mirror and the deflection mirror surface. A light beam deflected by a deflecting element at a first deflection angle is guided to the concave surface mirror via the transmission lens, and the light beam returned by the concave surface mirror is guided to the deflecting element via the transmission lens. In consequence, the deflecting element reflects the light beam twice, and the light beam is emitted toward a scanning lens at a second deflection angle which is larger than the first deflection angle.
