Abstract
A communication terminal apparatus (separate type portable telephone) separated into a first communication apparatus (parent device) and a second communication apparatus (child device), the first communication apparatus and the second communication apparatus in a separated state being wirelessly connected through direct communication. The communication terminal apparatus includes a joining detecting unit and a power supply control unit. The joining detecting unit detects joining between the first communication apparatus and the second communication apparatus. The power supply control unit performs control for conforming a power control state of the second communication apparatus to a power control state of the first communication apparatus if the first communication apparatus and the second communication apparatus are joined while the power control states are different between the first communication apparatus and the second communication apparatus.
