Publication number: 20240158192Abstract: A recording apparatus includes a feed roller, a conveyance roller, a recording unit, a reverse path, and a control unit. The conveyance roller conveys a sheet fed by the feed roller. The recording unit performs recording on the conveyed sheet. The reverse path reverses, in the reverse path, a traveling direction of the sheet on which the recording is performed. The control unit performs control so that a leading edge of a second sheet overlaps a first sheet on which recording is being performed by the recording unit. Recording on the second sheet is to be performed by the recording unit following the recording on the first sheet. The control unit performs control to reverse the traveling direction of the first sheet and the traveling direction of the second sheet in the reverse path while maintaining an overlapping state of the first sheet and the second sheet.Type: ApplicationFiled: November 10, 2023Publication date: May 16, 2024Inventors: SHO TAKAHASHI, MASASHI ITO, MOTOYUKI TAGUCHI, KEISUKE ARITA, KENTO TAMARI, RYOTA KOMATSU
