  • Publication number: 20230312299
    Abstract: A recording device includes a roll holding unit, a transport mechanism, a recording unit, a rear end detector, a cutting mechanism, and a control unit. The roll holding unit holds a roll in which a long medium is wound around a core body. The transport mechanism transports the medium supplied from the roll in a transport direction along a transport path. The recording unit performs recording on the transported medium. The rear end detector detects that all of the medium suppliable from the roll was supplied by the transport mechanism. The cutting mechanism cuts the medium in an intersecting direction intersecting the transport direction at a position between the roll holding unit and the recording unit. The control unit cuts the medium by the cutting mechanism based on rear end detection information from the rear end detector.
