摘要: The present invention relates to a small portable information processing apparatus. A GPS unit (11, 300) is attachable and detachable from rear surface of terminal (10, 350), so that the can be mounted on 350) make it serviceable only when necessary, thus improving convenience. Power supplied 300, 650) an antenna (112, 500, 613) set in state. This prevents exhaustion battery.
