Abstract
A portable communication device having a touch-screen locking unit that can prevent operation of the touch screen due to an unwanted screen touch is disclosed. The device comprises a main body housing having a touch screen. A mount is formed in the main body housing. An input unit is attached to or detached from the mount. A locking unit is provided on the mount and turns on/off a locking state of the touch screen according to attachment/detachment of the input unit. The locking state of the touch screen can be automatically set to an ON/OFF state by attaching/detaching a stylus pen to/from a mounting groove. When the touch screen is carried or kept, a touch screen operation or change according to an external environment can be prevented.
