  • Patent number: 9218089
    Abstract: A touch input device includes a touch panel, a controller, and a cancellation electrode. The touch panel includes a sensor pattern and an operation surface arranged above the sensor pattern. The sensor pattern includes first electrodes and second electrodes insulated from one another and arranged in a grid. The controller applies a drive pulse signal to the sensor pattern and detects a touch location where the operation surface of the touch panel is touched based on changes in capacitance of the sensor pattern. A cancellation pulse signal is applied to the cancellation electrode during application of the drive pulse signal. The cancellation pulse signal has a phase inverted from that of the drive pulse signal.

  • Patent number: 9196984
    Abstract: Provided is a substrate connection structure using a substrate connector capable of: ensuring a sufficient distance for adjusting positional misalignment even when the size and height of the substrate connector are reduced; preventing connector breakdown during the connecting operation thereof; and visually checking the connection thereof. A guide protrusion is provided at a mate-side end face of a guided portion so as to protrude farther beyond a mate-side substrate mounting surface when the plug is fitted into the socket. A first-side guide face is formed in an edge portion of an opening in a guide groove and the guide protrusion is provided with a second-side guide face slidable with the first-side guide face so as to lead the guided portion into the guide groove. Also, interference between the guide protrusion and the mate-side substrate is prevented from occurring.

  • Patent number: 9152233
    Abstract: A touch panel support structure that can transfer vibration of a touch panel to the operator even though a transparent protective plate is in tight contact with the surface of a case is provided. A rectangular touch panel is sandwiched at four corners between the transparent protective plate that is fixedly attached to the case near the four corners and backside support members so that the four corners act as the nodes of vibration. The antinode of waveform of vibration is located in an input operation area inside the four corners so that the touch panel can vibrate with a certain amplitude together with the transparent protective plate that covers the input operation area, even though the touch panel is fixed to the frame-like case along its periphery via the transparent protective plate, and thus vibration can be transferred to the operator.

  • Publication number: 20140333576
    Abstract: A touch type input device includes a touch panel having a sensor array of drive electrodes and sensor electrodes. Capacitors are formed at intersections of the drive electrodes and the sensor electrodes. A controller determines whether or not a conductive foreign matter exists on the touch panel from raw data values indicating a change amount in the capacitance of each capacitor from an initial reference value. Further, the controller determines whether or not the touch panel has been touched from control data values indicating a change amount in the capacitance of each capacitor from a control reference value that is changed for each capacitor in accordance with whether or not the foreign matter exists. When the raw data values indicate the existence of the foreign matter, the controller sets the control reference value of each capacitor to a raw data reference value corresponding to the present raw data value.
