  • 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.

  • Publication number: 20230256738
    Abstract: A recording device includes a sandwiching member coming into contact with a first guide shaft at a guide shaft-side contact surface and disposed between a carriage and the first guide shaft in a second direction and a cam member coming into contact with a first curved surface of the sandwiching member and configured to rotate about a first direction as a rotation axis relative to the carriage in a state of being engaged with the carriage. The cam member presses the first curved surface with the second curved surface slidably fitted to the first curved surface in the second direction and changes a position of the carriage relative to the sandwiching member in the second direction as a distance in the second direction of a position at which the second curved surface presses the first curved surface relative to the rotation axis changes along with rotation of the cam member.
