  • Publication number: 20230286293
    Abstract: A drying unit includes a housing and a first contact heating unit. The first contact heating unit is provided inside the housing. The first contact heating unit includes a first contact heating surface configured to come into contact with a back surface of a medium after printing. The first contact heating unit can change posture from first posture to second posture, in a state where a first engagement portion engages with a first guide portion of a first support portion and a second engagement portion engages with a second guide portion of a second support portion, by a movement from a first position where the first contact heating surface faces the back surface of the medium after printing to a second position where the first contact heating surface is more separated from the back surface of the medium after printing as compared to the first position.
