ABSTRACT:
Disclosed herein is a communication terminal which has an adequate structure for keys so as to sufficiently fulfill various communication services, to thereby make the communication terminal compact, and can control operation of the keys so as to minimize a data input error of the keys. The communication terminal includes a first housing, a second housing which is oppositely coupled to the first housing, and a control unit which interrupts operation of a data input part provided at either the first housing or the second housing according to movement of the second housing with respect to the first housing.
