Claim 0:
1. A light irradiation device that scans illuminating light, comprising:
a light source to emit light;
a first reflecting surface to reflect and deflect the light emitted from the light source and forming a planar-like image;
a second reflecting surface to reflect and deflect the light deflected by the first reflecting surface; and
a rotation mechanism to rotate the first reflecting surface around a first central axis passing through a center of the first reflecting surface and to rotate the second reflecting surface around a second central axis passing through a center of the second reflecting surface, wherein
the first central axis is orthogonal to a first reference surface as a virtual plane that is 45 degrees inclined with respect to a first plane that is orthogonal to an optical axis of the light incident upon the first reflecting surface,
the second central axis is orthogonal to a second reference surface as a virtual plane parallel to the first reference surface, and
the first reflecting surface is inclined with respect to the first reference surface and the second reflecting surface is inclined with respect to the second reference surface.
