  • Publication number: 20070120835
    Abstract: An input device is described, which is capable of quickly searching a part of information included in a large amount of continuous data (contents), and a scroll control apparatus using the input device. If a key input operation on one of the operation keys is performed through a key input unit while a low-speed scroll is being performed due to a slide operation performed on the key input unit, the low-speed scroll switches to a jump operation or a high-speed scroll. Thus, it becomes possible to quickly search a part of information included in a large amount of continuous data.

  • Publication number: 20070115002
    Abstract: A shielding member is provided as an electrostatic protection device in extension lines that extend from a sensing area to switching devices via extension areas correspondingly. As a result, even if a body to be detected such as a finger contacts the extension area, it is possible to reduce the amount of the change of an electrostatic capacitance with respect to the movement of the body to be detected. Therefore, it is possible to reduce influences exerted on data to be detected, and an electrostatic detection apparatus having improved coordinate detection accuracy can be provided.

  • Publication number: 20060077181
    Abstract: A composite capacitance between a common electrode and an X detection electrode having a plurality of detours is small, whereas lengths of parallel electrodes of the X detection electrode are set to have large values. A comprehensive composite capacitance is set to be constant by increasing a composite capacitance between the common electrode and the X detection electrode. For this reason, although the detours are formed in the electrode patterns, a coordinate position can be detected with high accuracy.

  • Publication number: 20050259081
    Abstract: An input device contains a plurality of push switch elements that are connected to a single switch signal line. When a switch signal is detected from the switch signal line, it is determined which push switch element is enabled based on coordinate data obtained from a primary input sensor. By using the coordinate data, only a single switch signal line is used to determine which push switch element is enabled.

  • Publication number: 20040196257
    Abstract: A thin input device is disclosed that is capable of simultaneously inputting rotational information and switching information. If a part of the human body H is rotated around a plurality of operating portions capacitance C is generated between the human body H and the respective electrodes, which are opposite to the human body H, in sequence. Therefore, a variation of the capacitance C corresponding to the respective operating portions is detected so as to obtain information on the rotational operation. In addition, if the operating portions are simultaneously tapped, the capacitances C of the electrodes are varied in sequence. Thus, simultaneous contact with the operating portions can be detected by detecting the variation of capacitance C.

  • Publication number: 20020126098
    Abstract: An input device has a combination of a plurality of capacitance- and flat-type detection members. Each detection member can be switched on and off, and an indicator indicating an individual input portion is formed on the surface of the detection member. A controller provided in the input device can switch between a single input mode and a motion input mode. In the single input mode, when one of the detection members is operated, data in accordance with the switching-on or switching-off of the operated detection member is generated. In the motion input mode, when some of the detection members are continuously operated, coordinate data in accordance with the positional relationship of the operated detection members is generated.
