Abstract

[Summary]

[Object]

An object of the present invention is to enhance operability of a mobile communication terminal to be foldable by directing a display panel outward.

[Means for Settlement]

A folding-type mobile communication terminal including a thin operation case 1 with an operation panel being formed, a thin display case 2 with a display panel being formed, and a movable connector 3 to connect the operation case 1 and the display case 2, in which transition can be made between a normal open state of expanding the both cases 1 and 2 by directing the operation panel and the display panel to the same direction, and a reverse close state of being folded by directing the display panel outward and opposing the main surfaces of the both cases, and having a main multifunction key 14 to be provided in the operation panel and capable of performing two or more different operation inputs corresponding to pressing portions, and a side multifunction key 26 to be provided in the end surface of the operation case 1 and capable of performing the same operations with the main multifunction key 14 to achieve the same operation inputs therewith.

Claims

1. A mobile communication terminal having a thin operation case with an operation panel formed on one main surface thereof, a display case with a display panel formed on one main surface thereof, and a movable connector to connect said operation case and said display case, and

being capable of making transition between a normal open state of expanding said both cases by directing said operation panel and said display panel to the same direction, and a reverse close state of folding said both cases with main surfaces faced to each other by directing said display panel outward, and comprising

an on-hook key provided on said operation panel,

a main guide key provided on said operation panel and having a function assignment displayed in said display panel, and

a sub guide key provided on said display panel, wherein

an on-hook function is assigned to said sub guide key during a telephone call in said reverse close state, and

the same function with said main guide key is assigned to said sub guide key during a standby time in said reverse close state.

2. A mobile communication terminal having a thin operation case with an operation panel formed on one main surface thereof, a display case with a display panel formed on one main surface thereof, and a movable connector to connect said operation case and said display case, and

being capable of making transition between a normal open state of expanding said both cases by directing said operation panel and said display panel to the same direction, and a reverse close state of folding said both cases with main surfaces faced to each other by directing said display panel outward, and comprising

an off-hook key provided on said operation panel,

a main guide key provided on said operation panel and having a function assignment displayed in said display panel, and

a sub guide key provided on said display panel, wherein

an off-hook function is assigned to said sub guide key during an incoming telephone call in said reverse close state, and

the same function with said main guide key is assigned to said sub guide key during a standby time in said reverse close state.

3. A mobile communication terminal having a thin operation case with an operation panel formed on one main surface thereof, a display case with a display panel formed on one main surface thereof, and a movable connector to connect said operation case and said display case, and

being capable of making transition between a normal open state of expanding said both cases by directing said operation panel and said display panel to the same direction, and a reverse close state of folding said both cases with main surfaces faced to each other by directing said display panel outward, and comprising

an off-hook key provided on said operation panel,

a main guide key provided on said operation panel and having a function assignment displayed in said display panel, and

a sub guide key provided on said display panel, wherein

an off-hook function is assigned to said sub guide key in the case of making transition to said reverse close state after inputting a number in said normal open state, and

the same function with said main guide key is assigned to said sub guide key during a standby time in said reverse close state.
