An input apparatus for a hand-held information processing device. The input apparatus has a main connection port adapted to connect the hand-held information processing device and a transmission port adapted to connect a computer. The input apparatus also includes a route selection unit and a user selection device. The route selection unit, coupled between the main connection port and the transmission port, is configured to selectively establish a transmission route between the main connection port and the transmission port. The user selection device is configured to selectively output a first logic level and a second logic level. Further, the route selection unit cuts the transmission route when the user selection device outputs the first logic level, and the route selection unit makes the transmission route conductive when the user selection device outputs the second logic level.
