A control section outputs a control signal. An actuator is connected to a drive section and operates based on the control signal. An operation information acquisition section acquires operation information related to an operation status of the actuator. A storage section stores correction information included in control information which includes a relationship between an operation status and the control signal. The correction section determines whether or not the control signal and the operation status are consistent with the control information, and when inconsistent, corrects correction information for consistency.
