ABSTRACT:
A character input frame is displayed in a popping-up manner and erased automatically in a position in which an operator desires to effect a handwriting input. A character input frame information generating section generates character input frame information based on coordinate input position information from a coordinate input section, and stores the information in a first storage section. A character recognizing section recognizes a character extracted by a character extracting section, and stores character code data of the result of recognition into a second storage section. A display control section displays in a popping-up manner the character input frame from an initial input position on a display panel based on the character input frame information from the first storage section. The character input frame information generating section erases storage contents of the first storage section based on recognition completion information from the character recognizing section. The character input frame is automatically erased when the character recognition is completed. During operation, the character input frame is composed of a mere frame where its cells are internally transparent, so that a printing type is not hidden behind the frame.
