Abstract
An optical scanning device that emits a light beam and scans a scanning subject with the light beam, includes: a holder mounted with a light source that emits the light beam, a collimator lens that converts the emitted light beam to approximately collimated beam, and a slit that interrupts apart of the collimated beam; a deflector having a reflecting surface, the deflector deflecting the light beam emitted from the light source; a cylindrical lens that focuses the light beam that has passed through the slit onto the reflecting surface of the deflector; and a frame having a base stage that is mounted with the deflector and the cylindrical lens. The holder is fixed to the frame by bonding with an adhesive in such a manner that a bottom end portion of the holder is spaced from a top surface of the base stage.
