Abstract
Disclosed is a folder operating apparatus for a cellular phone which can stably open and close a folder by compensating for the phase difference caused by the instability and the load of the folder operating apparatus by controlling the position of the folder. The folder operating apparatus includes a rotating section provided in a folder and having driving means for generating a driving force, a fixing section, connected to a body, for rotatably supporting the body at both sides of the rotating section, a power transferring section provided with a pair of members connected to the driving means and the fixing section, and selectively engaged together to face each other, an elastic means for applying to the power transferring section a supporting force greater than a driving torque of the driving means, and being elastically compressed so that the members of the power transferring section are separated from each other when an external force is applied to the folder, and position detecting means, installed at corresponding positions of the rotating section and the power transferring section, for controlling the driving means when the rotating section and the power transferring section are in a same-phase state.
