The rotating member includes a front end portion protruding from the loading surface and rotates about a rotary shaft by being in contact with the loaded document. The detection unit detects rotation of the rotating member and detects presence or absence of the loaded document. The feeding roller feeds the document by being in contact with the document loaded on the loading surface. The support portion rotatably supports the rotary shaft. When the rotary shaft is viewed from an axial direction, the rotary shaft includes a recessed portion recessed from an outer periphery section of the rotary shaft toward a shaft center of the rotary shaft. The support portion is in contact with the recessed portion to rotatably support the rotating member."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Document conveyance apparatus, image reading apparatus, and image forming apparatus","description":"A document conveyance apparatus includes a loading portion having a loading surface for a document, a rotating member, a detection unit, a feeding roller, and a support portion.
