PROBLEM TO BE SOLVED: To provide a technique capable of suppressing deterioration of detection accuracy of a sensor by making a physical relationship between the sensor and an object proper.SOLUTION: An image recording device comprises: a sensor for detecting a state of an object and outputting a detection value; a drive unit capable of moving the sensor in a direction coming close to the object and in a direction separating from the object; and a control unit for changing the physical relationship between the sensor and the object by the drive unit, and based on the detection value of the sensor, executing calibration for positioning the physical relationship between the sensor and the object. |
