A cutting plotter includes a medium supporter, a first guide rail, a second guide rail, a carriage, a work tool, a working controller, and a second direction displacement detector. The second direction displacement detector is configured to measure a second guide rail displacement amount. The second guide rail displacement amount indicates a magnitude of displacement of a moving path of the carriage from a predetermined moving path with respect to the second guide rail in a direction perpendicular to a second direction when the carriage is moved in the second direction along the second guide rail. The working controller is configured to execute a control in which a movement control of the second guide rail on the first guide rail is added so that the second guide rail displacement amount is corrected in a movement control of the carriage on the second guide rail.
