Patent attributes
A scanning mechanism that scans a scanning object with a light beam has light-collecting means for collecting the light beam that is emitted by a light source; driving means for driving the light-collecting means in a direction orthogonal to an optical axis of the light-collecting means; first reflecting means provided near a first side of the scanning object, for reflecting the light beam collected by the light-collecting means to allow the light beam to be incident on the scanning object; and second reflecting means provided near a second side of the scanning object that is opposite to the first side of the scanning object, for reflecting the light beam collected by the light-collecting means to allow the light beam to be incident on the scanning object.
