CONSTITUTION:A file 7 stores the data to be displayed on a screen, a protection level, the input data indicated by a data input device 3, and the approval information are stored. These stored items are inputted and outputted via a file input/output means 6. In a data input mode, a protection level deciding circuit 5 compares the protection level at which the approved item extracted based on the criterion of approval with the protection level set to the data input item. Based on the result of said comparison, a data input guide is positioned at the corresponding data input item by a data input guide circuit 4. Thus the input of data is possible via the device 3. Such integrated control is carried out by a display control means 2. |
