Abstract
When data is keyed in by operating a keyboard K displayed in a touch panel input area 14a, its character code is stored in a real data memory 46b of a RAM 23 and data on its attribute, pointer and data length is stored as management data. When handwritten data is input by manipulating a handwriting board P displayed in the input area 14a, coordinate data corresponding to the locus of the input handwritten data is stored in the real data memory, and data on its attribute, pointer and data length is stored as management data. The keyed-in data including the character code and the handwritten data including image data are both displayed in an output area 14b on the basis of the real data and its management data. Data edition including data erasure can be dealt with in a unified manner.
