Description

technical field [0001] The present invention relates to a portable electronic device such as a PDA that can browse and edit data on a screen of a display unit. Background technique [0002] Conventional compact PDAs (portable_digital_assistants: portable digital assistants) are portable electronic devices that can be miniaturized by eliminating the keyboard and can be operated with one hand. Various products are being developed and put into practical use as personal information management tools. For example, there is known a compact PDA that can cooperate with a personal computer to view and edit data, and can use a modem and a mobile phone to send and receive e-mails and faxes, and to access the Internet. [0003] However, since the keyboard is omitted, it is difficult to use only the main body of the PDA, and it is necessary to cooperate with a personal computer. Therefore, there is a problem that it is not suitable for the operation of newly inputting data, and its use i...
