Since a editing character string is managed by an input server, an application device cannot know whether scroll is necessary. Accordingly, there has been a problem that it is impossible to realize the scroll function. A receiving unit ( 221 ) receives an instruction from a user operation or an application device ( 210 ). A character string editing unit ( 223 ) edits a character string according to the instruction received. An output management unit ( 224 ) manages output. A state notifying unit ( 225 ) notifies a change of the internal state to the application device ( 210 ). When the output area ( 243 ) does not have enough empty space to display an editing character, the state notifying unit ( 225 ) instructs the application device ( 210 ) to shift the confirmed character string. The application device ( 210 ), upon receiving the instruction, scrolls the confirmed character string upward.
