ABSTRACT:
An input unit outputs handwritten data as stroke data to a control unit. The control unit stores the outputted stroke data in a handwritten memo database without recognizing the handwritten data as character code data, and stores stroke data of a retrieval mark in a mark database. The control unit classifies stroke data sets in each page into categories, such as characters and figures, and stores the classification result as retrieval information in the handwritten memo database. On receiving an indication of a retrieval mark or an indication of a retrieval key related to page contents, such as character contents or figure contents, from the input unit, the control unit searches the mark database or the handwritten memo database, and makes a display unit display handwritten data in the pages matching the indication.
