SOLUTION: Part of displayable images 45 which are displayable image data is first displayed by a moving front surface screen 40a. In such a case, the device is provided with a mouse icon 43 for indicating the position currently pointed by a mouse on the display screen 40. Further, the after-moving screen 40b for displaying the image after the scroll is illustrated. The block indicated by the mouse icon 43 is selected by a scroll operation.
