A DVD player (1) performs Voronoi partition by using the coordinate of the start of a rectangular region and the coordinate of the end thereof in button position information recorded on a DVD (14) and sets the reaction region of a new touch panel on the basis of the partition line acquired by the Voronoi-partition. Alternatively, the DVD player (1) defines the region in which information with the rectangular region size which is easily depressed and the number of title character strings are expanded (the information with the rectangular region size which is easily depressed X the number of title character strings) as the reaction region of the touch panel by using the number of title character strings recorded on the DVD (14) and the information with the rectangular region size which is easily depressed with a finger or the like. Further alternatively, the DVD player (1) scans the character string of a menu image to be displayed, performs the character recognition, acquires the coordinate position of the characters, and defines the characters of the coordinate position closest to the button position information (highlight information) as the reaction region of the touch panel.
