OPTICAL SCANNING DEVICE

摘要

An optical scanning device of the invention includes: a substrate main body (20); two cantilever beam portions (19) which protrude from both-side portions of one side of the substrate main body (20); a mirror portion (13) whose both-sides are supported by torsion bar portions (12); a drive source (11) which causes the substrate main body (20) to oscillate; and a light source which projects light onto the mirror portion (13), where the mirror portion (13) resonates and vibrates in accordance with a vibration imparted to a substrate (10), and a direction of reflection light from the light projected onto the mirror portion (13) from the light source changes in accordance with the vibration of the mirror portion (13), and where a fixed end portion (21) is fixed to a supporting component (16), and the drive source (11) is provided on a portion of the substrate main body (20).
