While names of data and icons are displayed on a selection-purpose display medium, a user selects data. Since the selection-purpose display medium is constituted by such a display medium capable of displaying a moving picture, operability by the user may be guaranteed. The content of the data which is selected by the selection-purpose display medium is displayed on a contents-display-purpose display medium. Since the contents-display-purpose display medium is constituted by a display medium having a memory characteristic, power consumption may be reduced, and this display medium having the memory characteristic may be dismounted. Since the display screen for the selection operation and the display screen for the contents display operation are separately provided, the user can perform the work by viewing the content of the data in correspondence with the data, so that the work efficiency can be increased.
