The sensing unit 156 detects a current state of the portable terminal such as an open / closed state of the portable terminal, a position of the portable terminal, presence or absence of a user contact, and generates a sensing signal for controlling the operation of the portable terminal. For example, when the portable terminal is in the form of a slide phone, whether the slide phone is opened or closed is sensed so as to output a sensing result to the controller 150 to control the operation of the terminal. In addition, it is responsible for sensing functions related to whether the power supply unit 127 is supplied with power, whether the interface 126 is coupled to an external device, and the like.

The interface 119 may be connected to a mobile terminal such as a wired / wireless headset, an external charger, a wired / wireless data port, a card socket (eg, a memory card, a SIM / UIM card), or the like.
