The guide portion is arranged above the placement portion and extends toward the placement portion, and guides the sheet toward an abutment portion in a case where the sheet on the placement portion conveyed in a second conveyance direction opposite to the first conveyance direction by a reverse conveyance portion comes into contact with the guide portion. The sheet dropping portion located at the lower position overlaps a part of the guide portion when viewed in a rotational axis direction of the pair of conveyance rotary members. ------------------------------------------------------------------------ OpenTechnical publication OT-2026-000000716 Published 2026-09-15T19:03:17.662911Z https://opentechnical.org/p/OT-2026-000000716
