Abstract: A mirror unit includes an optical scanning device, a frame member, and a window member. The frame member includes first and second wall portions facing each other in an X-axis direction. The first wall portion is higher than the second wall portion. The window member is disposed on a top surface of the first wall portion and a top surface of the second wall portion and is inclined with respect to a mirror surface of the optical scanning device. In a cross-section parallel to the X-axis direction, the first wall portion is separated from a first line passing through a first end at a side of the first wall portion in the mirror surface and a first corner portion formed at the side of the first wall portion by an outer surface opposite to the frame member and a first side surface in the window member.

Abstract: In a mirror unit, a first wall portion is higher than a second wall portion. A window member is disposed on a top surface of the first wall portion and a top surface of the second wall portion and is inclined with respect to a mirror surface. When any one of first to fourth wall portions is set as a first reference wall portion, in a cross-section perpendicular to the first reference wall portion, a first line passing through a first end at a side of the first reference wall portion in the mirror surface and a first corner portion formed at the side of the first reference wall portion by an outer surface and a first side surface in the window member intersects the first wall portion. A wiring portion includes a portion extending inside a base and leads outside a frame member.

Abstract: In an optical device, a mirror surface is provided in a movable portion. A support portion supports the movable portion through an elastic connection portion. A force generator generates force in the movable portion. A drive controller outputs a drive signal that operates the force generator. The movable portion has a resonance frequency higher than a frequency of the drive signal output from the drive controller in a state before the elastic connection portion is heated. The movable portion swings due to the elastic deformation of the elastic connection portion in response to the force of the force generator. A heat controller acquires a signal that indicates a swing state of the movable portion and performs, based on a phase of the acquired signal, feedback control of heating of the elastic connection portion by a heater.
