    Abstract: A cutting plotter includes a driving roller, a rotating shaft, pinch rollers, a cutter, and a press roller. The driving roller extends in a direction of a first axis and rotates around the first axis. The rotating shaft extends in a direction of a second axis parallel to the first axis, and is configured to be rotatable around the second axis. A passage through which a cutting target passes is formed between the driving roller and the rotating shaft. The pinch rollers are provided on the rotating shaft. The cutter is selectively pressed to the cutting target. The press roller is provided on the rotating shaft between the pinch rollers, and presses the cutting target against the driving roller. The press roller is formed by a coil spring into which the rotating shaft is inserted.
