Embodiment Construction
[0029] Hereinafter, a mobile phone as an electronic device will be taken as an example to illustrate the structure of the input device in the following preferred embodiments.
[0030] figure 1 is a plan view showing a schematic structure of a mobile phone for explaining an embodiment of the present invention. The mobile phone of this embodiment is constructed by arranging the following elements: a display unit 2, which is equivalent to an example of a display part for displaying information; a first operation key 3, a second operation key 4, and a third operation key 5, which constitute a complex type input device in which a plurality of operation input parts are adjacent to each other; and a numeric keypad 6 for inputting telephone numbers or characters.
[0031] The display unit 2 is composed of a liquid crystal display (LCD), and displays stored information or received information, which is a menu indicating service contents or corresponding to a menu, according to an inst...

Even if a plurality of operation entering means are closely disposed so as to perform a variety of operations, the operability is not degraded, and occurrence of operator's unwilled erroneous operations is prevented. When receiving an operation signal of a second entering apparatus (22) from a second entering control part (24), an entering management part (25) determines, from an operation signal form a first entering control part (23), whether a first entering apparatus (21) is now under a depressing operation. If the first entering apparatus (21) is now under a depressing operation, the entering management part (25) regards, as invalid, and abandons the operation signal of the second entering apparatus (22). Moreover, during an interval from a time when the first entering apparatus (21) is released to a time when a predetermined time period has lapsed, the entering management part (25) also regards the operation signal of the second entering apparatus (22) as invalid. When receiving device data from the second entering apparatus (22), the second entering control part (24) does not notify the entering management part (25) and makes the entering from the second entering apparatus (22) invalid during a predetermined interval from a time when a depression of the second entering apparatus (22) is commenced, thereby preventing the second entering apparatus (22) from being erroneously operated as a pressure-sensitive operation entering device.
Description
technical field [0001] The present invention relates to an input device for portable electronic devices and the like. Background technique [0002] Recently, with the diversification of functions of electronic devices such as portable electronic devices, input devices corresponding to complex operations have been required. For example, a mobile phone is provided with direction operation keys for performing an operation of selecting items such as a display menu displayed on a display unit and for performing an operation of scrolling displayed contents. As the direction operation key used for such an operation, a four-way operation key is generally used. The four-way operation key is operated by pressing key switches arranged corresponding to the four directions of left, right, up, and down. In addition to the four-way operation key, various types of operation input members are known, including a roller-shaped input member that performs a rotation operation, a lever-shaped i...
