Abstract

A mobile terminal includes a sub-device that is attached thereto or detached therefrom, to remotely control the operation and state of the terminal. The mobile terminal includes: a sub-device having an input/output unit and attached to or detached from the terminal; and a controller configured to receive a user input via a certain communication path from the sub-device when the sub-device is separated, and control elements and applications of the terminal according to the user input.

Claims

1. A mobile terminal comprising:

a main device having a display and being shaped to define an area accessible via an opening; and

a sub-device configured to be received within the main device via the opening, wherein the sub-device comprises a pen-type object;

a controller configured to;

cause the mobile terminal to transition to an unlocked state upon decoupling of the sub-device from the main device.
