When the user executes the message writing function, the controller 180 controls to display the keypad on the second display area 151B of the display 151 according to a predetermined setting (S101). Thereafter, when the user inputs a control command for changing the size of the keypad while the keypad is displayed on the display 151, the controller 180 adjusts the size of the keypad according to the control command (S103).

For example, when a drag in a predetermined direction is detected in the second display area 151B where the keypad is displayed, the controller 180 enlarges or reduces the keypad at a predetermined ratio. In other words, if a clockwise drag is detected as shown in FIG. 6A, the keypad is enlarged at a predetermined rate every time a drag is detected, and a predetermined ratio is detected each time a counterclockwise drag is detected as shown in FIG. 6B. To shrink the keypad. In this case, while the size of the second display area 151B on which the keypad is displayed remains the same, the size of the keypad may be changed or the size of the second display area 151B may be changed according to the size of the keypad. . In this case, as the second display area 151B increases, the first display area 151A decreases by the increase, and the first display area 151A should display at least one line of data.

In the present embodiment, only the clock / counterclockwise drag is shown, but when a drag is detected in one of the up, down, left, and right directions, the size of the keypad may be changed in that direction or the size of the entire keypad may be changed in proportion to the direction. . For example, when the drag operation is performed in the vertical direction, the size of the keypad may be changed only in the vertical direction or in the horizontal direction in proportion to the vertical direction.

In addition, as shown in FIG. 7, the mobile terminal enlarges the size of the keypad by a certain ratio when dragging in the diagonal direction of the upper right, and reduces the size of the keypad by a predetermined ratio when dragging in the diagonal direction of the lower left.

Subsequently, the controller 180 determines whether the size of the adjusted keypad exceeds a predetermined size (S105). For example, the controller 180 determines whether the size of the keypad exceeds the size of the second display area 151B or exceeds a predetermined limit size.

If the size of the keypad exceeds a predetermined size, the controller 180 controls the display 151 to display the scroll means 300 on one side of the second display area 151B on which the keypad is displayed (S107). The display 151 displays the scroll means 300 at a predetermined position of the second display area 151B under the control of the controller 180. For example, the horizontal scroll bar is displayed at the lower end of the second display area 151B, and the vertical scroll bar is displayed at the right end of the second display area 151B.

In the present exemplary embodiment, the scroll means 300 is displayed at a predetermined position, but the position at which the scroll means 300 is displayed may be changed by the user.

Meanwhile, if the size of the keypad does not exceed the predetermined size in step S105, the keypad whose size is changed is displayed on the second display area 151B as it is. In this case, the mobile terminal does not display the scroll means 300 because the entire keypad is displayed on the second display area 151B.

Then, when the manipulation of the scroll means 300 is detected, the controller 180 moves at least one row or one column of the keypad according to the manipulation of the scroll means 300.

This embodiment describes adjusting the size and area of the keypad by adjusting the keypad display area.

As shown in FIG. 9, in a state in which a QWERTY-based keypad is displayed (S201), the user moves the boundary of the second display area 151B where the keypad is displayed to perform a drag operation. In this case, the display 151 detects a touch for the drag operation by the touch and informs the controller 180. The controller 180 changes the size of the second display area 151B according to the boundary movement of the second display area 151B (S203).

The controller 180 detects the drag operation by the display 151 and calculates a size change ratio of the keypad based on the distance that the boundary of the second display area 151B is moved. The controller 180 readjusts the size of the keypad based on the calculated ratio (S205).

When the size of the readjusted keypad exceeds a predetermined size, as shown in FIG. 9, the controller 180 displays the scroll means 300 in the second display area 151B where the keypad is displayed (S207, S209). ).

On the other hand, if the size of the changed keypad is less than or equal to a predetermined size, the controller 180 changes the size of the keypad by the calculated ratio and outputs it to the display 151. The display 151 displays the changed keypad in the second display area 151B.
