ABSTRACT:
The present invention provides a foldable portable communication terminal device including a main body case and a lid case openably connected. The main body case has a side portion provided with an up key and a down key. The portable communication terminal device has a secondary battery, power supplying switch, and a control circuit incorporated therein. The control circuit switches the power supply switch to on/off when the up key and the down key are held depressed at the same time for at least the predetermined period of time. This starts or stops power supply from the secondary battery to the device body to switch the power source of the device body to on/off. Accordingly, the foldable portable communication terminal device can be realized which is adapted to turn off the power source of the device body with the main body case and the lid case folded together.
