Portable terminal

Abstract

A portable terminal has a first housing having at least a display unit, a second housing having at least a main input unit, and connected openably and closably to the first housing, and an auxiliary input unit arranged on a surface other than mutually facing surfaces of both of the housings in a closed state. The display unit is visible to user in a closed state and an opened state, a screen on the display unit is able to display a first selection screen which is appropriate for an operation by the auxiliary input unit when both of the housings are in a closed state, and a screen on the display unit is able to display a second selection screen which is appropriate for an operation by the main input unit when both of the housings are in an opened state.

Description

technical field [0001] The present invention relates to portable terminals such as mobile phones and PDAs (Personal Digital Assistants), and more particularly, to such a stackable portable terminal device, which is composed of a plurality of housings that can be connected to be stacked. And in other states, the display surface of the display part provided in any one of the casings can be exposed outside, and output information can be displayed on the display surface even in any state. Background technique [0002] Until now, as a folding type portable terminal device that can fold two casings, such as Figure 12 A foldable cellular phone 2 as shown is generally known. In this foldable mobile phone 2, a display surface 12 such as an LCD (liquid crystal display) for displaying output information and a speaker 13 are provided on an inner surface 10 of one housing 4, and a main operation part is provided on an inner surface 14 of the other housing 6. 16 and microphone 15.

Problems solved by technology

[0010] However, when displaying a selection screen for one-dimensionally arranging text-displayed items on a display surface with a limited size like the cellular phone 2, if you want to arrange a plurality of items at once, the text will become smaller, which is difficult to see visually. On the contrary, if the text is made larger, in order to reduce the number of items that can be displayed at one time, when searching for a specific item, the selection screen must be scrolled through the operation of the auxiliary operation key, so in terms of operability there are inconveniences

[0011] Moreover, in the existing overlapping type portable terminal device, since the above-mentioned selection screen is displayed regardless of the overlapping state and the open state, it is possible to select up, down, left, and right by the cross-shaped keys of the main operation part in the open state, Even so, in the case of selecting items on the selection screen, since only up, down, left, and right operations are used, there are also functions that cannot fully utilize the main operation part.
