description Provided is an optical scanning device that can be downsized and improve the reading rate of a laser-type image reading system. This is an optical scanning device that includes a torsion beam, and a variable focus mirror that is supported by the torsion beam. Furthermore, the variable focus mirror is supported at two symmetrical positions with respect to the axis of rotation of the torsion beam.
