Abstract
When a search character string is input via a key input section and a handwriting input section, if a spelling is input, a character is input directly by a key input operation or a recognized character is input by a handwriting input operation. If pinyin is input to input a Chinese character, not only are alphabetic characters input by a key input operation, but also the four tones area input by touching a four-tone input screen displayed on the handwriting input section. Accordingly, not only can ordinary characters be input as usual, of course, but also Chinese-specific four tones can be input easily by a touch operation at the handwriting input section even when a pinyin character is input.
