Abstract: PURPOSE:To easily drive a large sized scanning mirror by utilizing interference of a laser beam reflected on a mirror face part. CONSTITUTION:This driving device of a scanning mirror is provided with a magnetism generation part 2 having a coil 2a, and a flat plate shaped scanning mirror 1 which is angularly displaced and driven according to the magnetism of the part 2 generated by electrifying the coil 2a so that the light reflected with a mirror face part 1b is scanned. The scanning mirror 1 is supported with supporting members 1d at both ends capably of being angularly displaced centering around a drive axis 1e connecting both end parts, one face side is formed into a mirror face part 1b, the other face side is formed into a thin film-like permanent magnet 1c of which both sides of the drive axis 1e are magnetized into different poles, the part 2 having the winding axis of coil 2a in the direction meeting at right angles with the drive axis 1e of the mirror 1 is arranged on the other side of the mirror 1 spacedly by a decided distance. Consequently, the mirror 1 is singly driven in the light weighted condition of only forming the thin film-like permanent magnet 1c on the other side, and hence it can be driven by relative small drive force even in case of its large size.
