摘要
A beam deflecting device for scanningly deflecting a beam, comprising a rotational mirror (3) for reflecting the light beam, the rotational mirror having two opposite side surfaces (3a, 3b) effective to reflect the beam, wherein only the two surfaces are used for scanningly deflecting the beam, and a driver (13) for rotating the rotational mirror in one direction to scanningly deflect the beam. The rotational mirror may have one side surface effective to reflect the beam, wherein only the one surface is used for scanningly deflecting the beam. The rotational mirror has a non-use portion not used for scanningly deflecting the beam, the non-use portion being provided with at least one groove (15).
