Embodiment approach 2

[0143] Figure 11 (a) shows a case where, with respect to the operation key 62 arranged adjacent to the pressing surface of the film of the electrostatic pad 61 , the area on the film adjacent to the pressing surface is used as the input start prohibited area C1 . In this case, the operation key 62 is arranged such that its pressing surface (key top) is adjacent to the edge of the lower side of the thin film of the electrostatic pad 61 .

[0144] With this configuration, even when the electrostatic pad 61 and the operation key 62 are arranged adjacent to each other, the direction input signal can be appropriately generated according to the operation position at the start of the movement, so when the operation key 62 is operated, errors can be suppressed. A direction input for controlling the display position of the image information is performed.

Embodiment approach 3

[0146] Figure 11 (b) shows a case where, with respect to the operation key 62 arranged to overlap a part of the pressing surface with the thin film of the electrostatic pad 61 , the area on the film including the overlapping area C3 is used as the input start prohibited area C2 . In this case, the operation key 62 is arranged such that its pressing surface overlaps with the lower end of the thin film of the electrostatic pad 61 .

Embodiment approach 4

[0148] Figure 11 (c) shows that with respect to the operation key 62 arranged to overlap the entire pressing surface with the film of the electrostatic pad 61, the edge 61a of the film including the overlapping area C5 and the film closest to the overlapping area C5 is sandwiched between the overlapping area C5 In the case of holding the area C6 as the input start prohibited area C4.

[0149] In this case, the entire pressing surface of the operation key 62 overlaps the thin film of the electrostatic pad 61 , and the region sandwiched between the overlapping region C5 and the lower edge 61 a of the thin film becomes the region C6 .

[0150]With this configuration, since the input start prohibition area C7 includes the overlapping area C5 of the pressing surface and the film, and the area C6 sandwiched between the end edge 61a of the film and the overlapping area C5, when the operation key 61 is operated, it is possible to effectively to prevent unintentional directional inpu...

Abstract

A mobile information terminal is provided with an operation position detecting unit (37) for detecting a user's operation position based on an output of an electrostatic capacitance sensor (30) comprised of thin films with a plurality of electrodes to detect a electrostatic capacitance of each electrode, a directional input control unit (31) for detecting the movement of the operation position based on an output of the operation position detecting unit to generate a directional input signal, a key input unit (32) for detecting a user's pressing operation against an operation key pressing surface to generate a key input signal, a display (22) having a display screen, and a display control unit (34) for controlling a display position of image information in a display screen based on the directional input signal. At least a part of the thin film of the electrostatic capacitance sensor (30) is made to overlap with a part of the pressing surface of the operation key and the directional input control unit (31) judges whether to generate the directional input signal based on an operation position at movement starting time in the case of the detection of the operation position movement. In the case of the operation of the key disposed to overlap with an electrostatic pad, a mistake of the directional input for the movement of the screen display can be suppressed.

Description

technical field [0001] The present invention relates to a portable information terminal and a mobile phone. More specifically, the present invention relates to an improvement of a portable information terminal having a sensor for detecting an operation position by utilizing a phenomenon in which electrostatic capacitance of an electrode changes due to a user's operation. Background technique [0002] A capacitive touch pad (hereinafter referred to as an electrostatic pad) is known as a sensor that detects the user's operation by utilizing the phenomenon that the electrostatic capacity of the electrode changes due to the user's operation, so as to determine the position of the operation. . The electrostatic pad is an indicator for input corresponding to an operation position, and is used for scrolling a screen display, moving a cursor, and the like. The scrolling of the screen display or the movement of the cursor is performed by detecting the movement of the operation posit...
