Embodiment Construction

[0014] Preferred embodiments of the portable terminal device of the present invention are described below. refer to figure 1 , a mobile phone as a specific example of the present invention includes a key operation unit 10 , a key detection unit 11 , a key determination unit 12 , a determination storage unit 14 , a device control unit 13 and a display unit 15 .

[0015] like figure 2 As shown, the key operation unit 10 has 10 numeric keys, a "*" key, a "#" key, and a clear key for clearing numbers and the like displayed on the display unit 15. The key detection unit 11 detects a pressed key. When a plurality of key buttons are pressed simultaneously, the key detection unit 11 detects all the pressed keys. For example, when the key detection unit 11 detects a pressed key within 100 milliseconds after detecting the first key, the key detection unit 11 knows that the key is pressed simultaneously with the first key. The period of time for judging the simultaneous depression o...

Abstract

The mobile phone disclosed in the present invention has a key operation unit in which a plurality of small keys are arranged close to each other. Users sometimes press multiple keys simultaneously. The mobile phone stores, for combinations of keys, data relating to the frequency with which the user has made key determinations in the past when these keys were pressed simultaneously. When a plurality of keys are pressed simultaneously, a key determined to be the highest frequency is selected, and a number corresponding to the key is displayed. Also, once the key is determined, the data on the frequency of determination of the key is updated.

Description

technical field [0001] The present invention relates to a portable terminal device with keys and a control method thereof, in particular to judging a pressed key among a plurality of pressed keys. Background technique [0002] In recent years, small portable telephones have been commonly used. A small portable phone has many keys arranged in a limited space. The keys are small and set close to each other. Therefore, in the key operation, the user of the cellular phone often depresses other key(s) provided near the desired key at the same time as the desired key. [0003] In existing portable phones, when a plurality of keys are simultaneously pressed, the key operation is prohibited, or the key pressed last is permitted. [0004] Japanese Patent Laid-Open No. Sho 58-105329 discloses a key selection method in which one of the above methods is selected. However, this method requires the user to repeatedly press the key. In Japanese Patent Laid-Open No. Hei 7-13666, when t...
