The illuminating device includes a plurality of first light sources arrayed on a circuit board, the first light sources having a plurality of first light emitting surfaces through which light is emitted, and a second light source disposed on an upstream side of the first light sources in an irradiation direction of the light. In the illuminating device, the second light source has a second light emitting surface through which light is emitted, and the second light source has a directivity angle different from a directivity angle of each one of the first light sources. The image reading device includes the illuminating device, and an imaging device to receive the light reflected by a document to capture an image of the document."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Illuminating device, image reading device, and image forming apparatus with multiple light sources","description":"An illuminating device, an image reading device, and an image forming apparatus.
