摘要： The keyboard includes a rubber sheet fixed on key tops of a set of key-switch devices. The rubber sheet elastically urges the key tops upward so that they are borne away from the base of the key-switch devices. The rubber sheet is arranged so as to cover the key-switch devices from outside. According to the invention, the cost of a keyboard covered with a dustproof and watertight rubber sheet can be reduced.

摘要： A push button-type switch device includes a pair of fixed contacts, an operable member to be pushed, an actuating member elastically deformable upon the operable member being pushed, a movable contact which short-circuits the pair of fixed contacts due to elastic deformation of the actuating member, and a limiting part arranged to limit a direction in which the operable member moves and making the operable member move in a fixed orientation. The limiting part includes a pair of link members that engage with each other, one ends of the link members rotatably supported by the base portion, and the other ends thereof slidably supported by the operable member. This produces a good click irrespective of a position where the operable member is operated.

摘要： Provided is a liquid crystal display device, including: a data line; a plurality of pixel circuits; an output grayscale value generating circuit for outputting an output grayscale value obtained by correcting a display grayscale value indicating a grayscale potential having one of positive polarity and negative polarity; and a data-line driving circuit for selectively outputting an output potential having one of positive polarity and negative polarity corresponding to the output grayscale value to the data line. The data-line driving circuit outputs the potential so that the positive-polarity output potential corresponding to a smallest output grayscale value becomes lower than a positive-polarity grayscale potential indicated by a smallest one of the display grayscale values and that the negative-polarity output potential corresponding to the smallest output grayscale value becomes higher than a negative-polarity grayscale potential indicated by the smallest one of the display grayscale values.

摘要： A data line driving section (6) outputs a video signal voltage for each pixel to a data line (DL) for each predetermined period in order. In outputting a video signal voltage for a pixel, the data line driving section (6) outputs a gradation signal voltage having a voltage corresponding to a gradation value of the pixel as the video signal voltage during a second part of the predetermined period, and outputs a correction gradation signal voltage different from the gradation signal voltage as the video signal voltage during a first part of the predetermined period. A control section (4) changes a relationship between the correction gradation signal voltage and the gradation signal voltage based on a combination of the gradation value of the pixel and a gradation value of a pixel preceding the pixel.
