Abstract:
1. A portable terminal device, comprising: a first casing configured to hold a first input device; a second casing; a second input device configured to receive an input operation at a plurality of positions; a control unit configured to allocate a function to be executed, in response to the input operation, to each of the plurality of positions; a connection configured to couple the first casing and the second casing, the connection being operable between a first state in which the first casing and the second casing are exposed and a second state in which the first casing and the second casing are overlaid such that the second input device is exposed; a state detecting unit configured to detect between the first state and the second state; and a posture detecting unit configured to detect a posture of the first casing; wherein the control unit is configured to, when the second state is detected by the state detecting unit, allow the function allocated to each of the plurality of positions to be changed according to the posture of the first casing detected by the posture detecting unit, and is configured to, when the first state is detected by the state detecting unit, not allow the function allocated to each of the plurality of positions to be changed according to the posture of the first casing detected by the posture detecting unit.
