Abstract:
1. An optical scanning device comprising: an oscillating mirror that reflects incident light; a first beam unit that is coupled to one end of the oscillating mirror, the first beam unit extending in a first direction; a second beam unit that is coupled to another end of the oscillating mirror; a first driving unit that is coupled to the first beam unit; and a first adjusting unit that is coupled to the first driving unit, the first driving unit being disposed between the first beam unit and the first adjusting unit, and causing the oscillating mirror to oscillate, the first adjusting unit adjusting a modulus of elasticity of the first beam unit by elastically deforming the first beam unit, and a length of the first driving unit in a second direction being shorter than a length of the first adjusting unit in the second direction, the second direction being perpendicular to the first direction.
