  • Publication number: 20240066872
    Abstract: A recording device has: a recording section that discharges a liquid to a medium for recording purposes; a maintenance unit that abuts the recording section and performs maintenance of the recording section; a first moving section that causes the recording section to abut the maintenance unit and separates the recording section from the maintenance unit; and a restricting section that can suppress movement of the recording section toward the maintenance unit after the recording section abuts the maintenance unit. The first moving section has a driving source and a worm gear that transmits the power of the driving source. A force with which the driving source causes the recording section to abut the maintenance unit is smaller than a force with which the driving source separates the recording section from the maintenance unit.
