Abstract: A cutter device including a transport unit for transporting a medium, a round blade configured to move, while rotating, in a width direction intersecting a transport direction in which the medium is transported, a fixed blade provided along the width direction, and a controller configured to control driving of the transport unit and a movement in the width direction of the round blade, in which the controller is configured, when the medium is cut by causing the round blade to move to a first direction of the width direction, to cause the round blade to move to a second direction being a direction opposite to the first direction while causing the round blade to rotate without causing the medium to move in the transport direction.

Abstract: A printing apparatus includes a power-supply unit, a printing unit, a circuit board (main wired board), and a cooling unit. The main-wired-board cooling unit includes: an inflow portion including an inlet from which air outside of a housing flows in, the inflow portion being disposed on a rear surface of the housing; a first flow path in which the air flowing in flows to a front surface side of the housing; a turn-around flow path causing the air flowing in the first flow path to be turned around to a rear surface side of the housing; a second flow path in which the air turned around flows to the rear surface side; a flow-out portion including an outlet from which the air flowing through the second flow path flows out to an outside of the housing, the out portion being disposed at the rear surface; and a fan (main fan) causing the air to flow in from the inlet and also causing the air passing through each of the flow paths to flow out from the outlet.

Abstract: A cutter device includes a pair of pulleys including a first pulley and a second pulley, an endless belt spanning the pair of pulleys, a holder that holds a movable blade and moves in accordance with a movement of the endless belt, a first sensor configured to detect that a position of the movable blade is at a first position, and a second sensor configured to detect that the position of the movable blade is at a second position. The first sensor and the second sensor are disposed at positions overlapping with the holder in an up-down direction. The holder includes a first arm protruding toward the first position and a second arm protruding toward the second position. The first arm faces the first sensor when the holder is at the first position, and the second arm faces the second sensor when the holder is at the second position.

Abstract: A cutter device including a transport unit for transporting a medium, a round blade configured to move in a width direction while rotating, and a fixed blade provided along the width direction, in which a rotation direction in which the round blade rotates when the medium is cut by causing the round blade to move to a first direction of the width direction coincides with the first direction, a rotational speed at which the round blade rotates when the medium is cut by causing the round blade to move to the first direction is set greater than a speed at which the round blade is caused to move to the first direction, and a thickness of the round blade is not less than 1 mm.

Abstract: A cutter device includes a fixed blade extending in a first direction, a fixed shaft extending in a second direction intersecting the first direction, a round blade that is rotatably supported by the fixed shaft, comes into contact with the fixed blade and moves in the first direction while rotating, and an urging portion that presses the round blade in the second direction along the fixed shaft. A load of the round blade pressing the fixed blade is at least 300 gf, a diameter of the round blade is at least 20 mm, and D/L is not greater than 2.0, where the diameter of the round blade is D and a length over which the fixed shaft supports the round blade is L.

Abstract: The peeling device has a pressing roller that comes into contact with a label attaching surface (a first surface) of the backing paper and a driving roller that comes into contact with a back surface of the backing paper. The peeling device includes a peeling plate that is provided on the upstream side of an interposing roller pair in a transport direction of the backing paper when the label is peeled off from the backing paper and that bends a transport path of the backing paper. The pressing roller is a split roller including a roller shaft and a plurality of rollers. The peeling device includes support frames that support the pressing roller, and coil springs that come into contact with the roller shaft in an area on the pressing roller between the support frames and that bias the pressing roller toward the driving roller.
