摘要： According to the present invention there is provided a space coordinates detecting device wherein a detecting section for detecting light emitted from a light source is provided, thereby permitting detection of a relative angle between a light emitting sections and the detecting section and hence permitting application of the detecting device to an input apparatus. The detecting section is provided with a light sensing element 23 having quartered light sensing portions. In the light emitting section, distinguishable lights are emitted from two light sources. The lights thus emitted are throttled through apertures and applied as separate square light spots S16 and S17 to the light-sensitive surface of the light sensing element 23. By calculating a difference in the detected output among the quartered light sensing portions, it is possible to determine the center I1 of the square light spot S16 and the center I2 of the square light spot S17. A relative rotational angle of the light emitting section and the detecting section with respect to Z axis can be determined by calculating an inclination angle .alpha. on X-Y orthogonal coordinates of a line x connecting both centers I1 and I2.

摘要： In a capacitance detecting circuit, changes in capacitances at intersections between a plurality of row lines and a column line are detected as voltages. The capacitance detecting circuit includes a column-line driver for driving the column line. A code generator generates code having orthogonality in chronological order. A selection synthesizer selects a certain number of row lines from the plurality of row lines by using the code and synthesizes measured voltages at the intersections between the selected row lines and the driven column line so as to output the synthesized measured voltage. A decoding computation unit separates the measured voltages corresponding to the capacitances at the intersections by performing product sum computation between the synthesized measured voltage and the code.

摘要： A light-emitting diode device includes a light-emitting diode, a lens cap made of synthetic resin, for covering the light-emitting surface of the light-emitting diode means, and a refractive layer formed between the light-emitting surface and the lens cap, the refractive layer having a composition, such as an air layer, with a refractive index different from the refractive index of said synthetic resin. In this arrangement the relationship between the light intensity and directional angles is shown by characteristics in which the light intensity is maximum in the center of the directional angles, and is relatively flat in the form of a sinusoid in the wide range of the directional angles. Therefore, even when the characteristics of each light-emitting diode is not verified, a predetermined light-signal transmission range is readily obtained without being affected by a scatter in the characteristics.
