KEY CONTROL APPARATUS OF A PORTABLE TERMINAL
First Claim
1. A key control apparatus for a portable terminal comprising a first housing with first and second display units and a second housing with first and second key input units, the key control apparatus comprising:
- a first key input unit comprising a plurality of touch-sensitive touch keys for implementing given functions, one or more mechanical keys, and a plurality of sensors for sensing the touching of the touch keys and implementing a scroll function;
a second key input unit comprising a plurality of mechanical keys for implementing given functions and functions corresponding to the keys arranged on the first key input unit; and
a control unit performing control in such a manner that when a touch key in the first key input unit is touched, a function given to the touch key is implemented, wherein if touching is sensed through a sensor among the sensors of the first key input unit within a predetermined length of time after touching is sensed through another sensor, the control unit performs control in such a manner that a scroll function is performed in a corresponding direction, and when the second housing is rotated, the control unit performs control in such a manner that predetermined keys among the mechanical keys of the second key input unit implement the functions corresponding to the touch keys.

Abstract
A key control apparatus for a portable terminal including a first housing with first and second display units and a second housing with first and second key input units is provided. The key control apparatus allows the functions of the portable terminal to be conveniently implemented. The key control apparatus includes a first key input unit, a second key input unit and a control unit. The first key input unit includes a plurality of touch-sensitive touch keys for implementing given functions, one or more mechanical keys, and a plurality of sensors for sensing the touching of the touch keys and implementing a scroll function. The second key input unit includes a plurality of mechanical keys for implementing given functions or functions corresponding to the keys arranged on the first key input unit. The control unit controls the apparatus so that when a touch key in the first key input unit is touched, a function given to the touch key is implemented. Further, if touching is sensed through a sensor among the sensors of the first key input unit within a predetermined length of time after touching is sensed through another sensor, the control unit performs control in such a manner that a scroll function is performed in a corresponding direction, and, when the second housing is rotated, the control unit performs control so that predetermined keys among the mechanical keys of the second key input unit implement the functions corresponding to the touch keys.
