DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an electronic notebook device with a tablet that stores image data and displays it on a display section as necessary.

[Prior Art and its Problems] An electronic notebook device with a tablet has been proposed that stores image data input through a tablet input section and displays it on a display section as needed. In this type of electronic notebook device, image data for one display screen is treated as a single piece of independent data. Therefore, for example, when a map is stored and displayed as image data, the degree of detail or range of the map is limited depending on the resolution of the display screen. For this reason, it has been virtually impossible to store and display a detailed map of a large area as image data.

[Object of the invention] This invention was made in view of the above-mentioned circumstances.
An object of the present invention is to provide an electronic notebook device with a tablet capable of displaying image data exceeding the display capacity of one screen of a display section.

[Summary of the Invention] This invention provides an area designation memory that stores a designated display area and an expansion memory that can store image data for multiple sides, and stores the corresponding image data from the expansion memory according to the contents of the area designation memory. By reading out the data and displaying it on the display unit, continuous image data for a plurality of double sides can be stored in association with each other, and image data corresponding to a specified position can be displayed.

[Embodiments of the invention] A practical example of the present invention will be described below with reference to the drawings.
