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： A remote coordinate designating device has a remote control with a light emitting device for emitting light, and a controller for detecting a designated position by receiving light from the remote control at a distance from the remote control. One cycle of a light signal from the light emitting device is composed of switch data and a coordinate detection timing header at the head, and a coordinate detection carrier. The switch data and the coordinate detection timing header use the same frequency as the normal remote control frequency band, and the frequency of the coordinate detection carrier is lower than the frequency of the switch data and the coordinate detection timing header. The switch data contains on-off information about a switch for pointing, and coordinate detection is started when a predetermined time has passed from the rise of a burst portion in the switch data.

摘要： A relative-angle detection apparatus which has an infrared-signal transmitting unit and an infrared-signal receiving unit. The transmitting unit includes a first light-emitting device array formed of a plurality of light-emitting devices disposed in a direction substantially coinciding with the fiducial axis for angle detection, and a second light-emitting device array formed of a plurality of light-emitting devices located to be slightly angled in the different directions with respect to the axis. The devices of the first light-emitting device array generate a continously-output first infrared signal in which an infrared signal is intermittently modulated by a first frequency and also modulated by a second frequency higher than the first frequency. The devices of the second light-emitting device array generate a second infrared signal in which an infrared signal is modulated by the first frequency and also divided into a plurality of signals so as to be output at different timings. The receiving unit detects and amplifies the first frequency contained in the first and second infrared signals and executes signal-processing on the amplified first frequency, thereby detecting the angle of the transmitting unit relative to the receiving unit.

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.

摘要： In the transmitter receiver of the present invention, a light-shielding sheet is arranged in front of a light-emitting portion having a LED whose light-emitting central axis is inclined and an aperture from which only the head of the light-emitting portion is exposed is made in the light-shielding sheet. The light-shielding sheet masks the inclined side portion of the light-emitting portion to prevent a light-receiving portion from detecting the light leaking from the inclined side portion. Therefore, the light-receiving portion can detect with high accuracy a change in the amount of light emission that is produced by a change in the direction of the light-emitting portion.
