Abstract
An optical scanner includes a frame, a light source, an optical member, and a spacer. The light source emits a light beam. The optical member is mounted on the frame to guide the light beam to a scanning target. The spacer maintains the optical member at a predetermined position with respect to the frame. The spacer is formed of a photocurable resin that is cured in response to a predetermined light having a wavelength within a prescribed range.
