  • Patent number: 9251977
    Abstract: An electronic apparatus of the present invention includes an operating portion formed by a non-conductive material, a rotating plate configured to rotate in accordance with a rotational operation of the operating portion, a substrate including a first sensing electrode whose capacitance changes by a touch operation to the operating portion and a plurality of second sensing electrodes whose potential changes by a rotation of the rotating plate on a surface different from a surface on which the first sensing electrode is disposed, and a detector configured to detect the capacitance of the first sensing electrode and the rotational operation of the operating portion based on an output from the plurality of second sensing electrodes. A protruding portion that protrudes toward the first sensing electrode is formed on the operating portion, and the protruding portion is formed on a lightening portion on a back side of the operating portion.

  • Patent number: 8987623
    Abstract: A slide switch capable of enhancing the accuracy of detecting a slide operation position of a slide lever and the operability of the slide lever without increasing the number of components and an installation space for the slide switch. An elastically-deformable click portion is disposed on a line passing through the center of a slide shaft of the slide lever and extending in a sliding direction in which the slide lever slides, moves integrally with the slide lever, and gets over a convex portion formed in a base member to generate a click force. In an accommodation space which accommodates the click portion and a plurality of armature portions, the click portion and one armature portion of the plurality of armature portions are separated from each other by a first partition, and the click portion and the other armature portion are separated from each other by a second partition.
