PROBLEM TO BE SOLVED: To improve a scanning device that is used for color measurements so as to be suitable for high-accuracy measurements without making any contact. SOLUTION: A support surface for the measured object, a drive unit for moving the color measuring head above the support surface in at least one-dimensional direction and for adjusting the height of the color measuring head in the direction perpendicular to the support surface, and a measurement and drive control unit which drives the drive unit and cooperates with the color measuring head are included. An electronic distance control system which adjusts the distance of the color-measuring head above a measurement point in a direction perpendicular to the support surface to a desired measuring distance for each measurement point by using the drive unit is also included. The scanning device is suitable for performing high-accuracy measurements above even the smallest measurement areas without contact, and further a separate measurement sensor is not needed for the distance control system.
