CONSTITUTION:Image information and a file name which are displayed on a display are stored in a subcode of a compact disk. The image information is transferred to an interface 31 by a font unit, and the file name and key part information are transferred to a system controller 11. Key information from a switch matrix 42 consisting of a transparent electrode in front of the display is also sent to the system controller 11, and an indicating pattern of the corresponding key part is prepared and given to the interface 31. On a screen 41, the key part information is displayed simultaneously with image information 43, and by depressing the matrix 42, the controller 11 retrieves a file from the key information and the file name of the image.</p> |
