The opening is formed in a first flat surface opposite to a surface into which an end surface of the light guide is inserted. The device also includes a housing, a light source base plate, and a base plate protection layer being formed on a region of the light source base plate other than at least a region on which a light source element is formed. At least one of the light source base plate and the second flat surface of the base plate protection layer is pressed against the housing or the first flat surface at a position at which light emitted by the light source element enters the end surface of the light guide exposed from the opening."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lighting device and image reading device","description":"A lighting device includes a rod-shaped light guide, a light guide holder, and an opening optically communicating with the hole.
