Abstract: A printing apparatus includes: a roll sheet container that contains a roll sheet around which a recording sheet is wound; a first sheet guide that makes contact with a first surface of the recording sheet; a second sheet guide that makes contact with a second surface of the recording sheet; and a transport roller that transports the recording sheet. The first and second sheet guides are disposed so as to face each other to form a sheet route along which the recording sheet is to pass. The transport roller transports the recording sheet that passed along the sheet route. The second sheet guide includes: a projection that protrudes toward the roll sheet container; and a pushing section that extends from the projection along an outer circumference of the roll sheet and in a direction away from the first sheet guide.

Abstract: A cutter apparatus is provided that includes a fixed blade and a movable blade positioned facing the fixed blade, and that is configured to cut a medium transported between the fixed blade and the movable blade. The movable blade includes: a guide portion that is driven to reciprocate between a standby position at a distance from the medium and a cutting position, where the movable blade intermeshes with the fixed blade, protrudes further toward the movable blade than a cutting edge of the fixed blade when the movable blade is in the standby position, and is pressed by the movable blade to move in a state of being contact with the fixed blade when the movable blade is in the cutting position; and a biasing member configured to bias the guide portion toward the fixed blade.

Abstract: A tractor unit has first and second tractors with tractor pins that engage sprocket holes on opposites sides of continuous paper. A tractor support shaft supports the tractors movably in the device width direction. A frame supports the tractor support shaft movably in the device width direction. A clamping mechanism is provided for fixing the second tractor on the tractor support shaft. The first tractor 31 is disposed at a reference position in the device width direction. A biasing member biases the tractor support shaft in a second direction when the tractor support shaft moves in a first direction opposite to the second direction.
