  • Patent number: 8077057
    Abstract: A capacitive input pad is provided at a position near input keys constituting a keyboard input unit. A left palm detecting unit and a right palm detecting unit are provided both sides of this input pad. When the left palm detecting unit and the right palm detecting unit detect both palms, an input operation, corresponding to a space key input area, an L-key input portion, or an R-key input portion, is performed through an operation of the input pad. When the left palm detecting unit and the right palm detecting unit do not detect both palms, a coordinate input operation is performed using the input pad.

  • Patent number: 7893921
    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.

  • Patent number: 7593001
    Abstract: An image-processing apparatus includes an input unit for inputting operational signals. The input unit includes an operation surface and outputs, as the operational signals, a position detection signal representing a detected operation position of an operation instrument moving on the operation surface and a selection confirmation signal generated when a selection operation is confirmed on the operation position. The image-processing apparatus further includes a display unit and a display-controlling unit for controlling the display state of the display unit based on the operational signals. The display-controlling unit highlights an index corresponding to the operation position when the position detection signal is output in a state in which indices to be selected are displayed on the display unit, and reads and displays main data corresponding to the highlighted index when the selection confirmation signal is output.

  • Patent number: 7589713
    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: 20090065267
    Abstract: An input apparatus includes a surface plate, an electrostatic capacitive sensor disposed under the surface plate, and a strain sensor disposed between the electrostatic capacitive sensor and the surface plate and fixed to the back surface of the surface plate. As a first input operation, when a finger is moved on an operation area of the surface plate, the movement position can be detected by the electrostatic capacitive sensor. As a second input operation, when the operation area is pressed down, the pressing force can be detected by the strain sensor. A series of the first input operation and the second input operation can be performed without leaving the finger from the operation area. Therefore, the input operation can be simply performed.

  • Patent number: 7492169
    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.

  • Patent number: 7312790
    Abstract: An input apparatus includes a flat input device of a pressure-sensitive type or a capacitive type, and an indicator sheet on which indication marks are formed is fixed on the surface of the flat input device. A tactile-feel-generating unit is provided behind the flat input device. The tactile-feel-generating unit includes dome-shaped inversion plates which are disposed at positions corresponding to the indication marks. When one of the indication marks is pressed setting an input mode, an operation signal is generated in accordance with an item represented by the indication mark, and a tactile feel is generated by a reaction force of the corresponding inversion plate. When an indication mark is touched, while in an input mode, the control unit recognizes the resulting signal to be a coordinate data signal.

  • 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.
