摘要： An apparatus is disclosed for inclination detection wherein infrared transmitted signal, signal groups S1, S2, S3, . . . including a leader code, a parity bit and bits for data transfer are sequentially transmitted with an interval time t3. At each bit of the signal group S1, "1" and "0" of a binary signal expressing the data are not inverted, at the signal group S2, "1"and "0" expressing the data are inverted, and inversion and non-inversion are repeated every signal group. At bits of each signal group, since a time length expresses "1" and "0", a total time length of each signal group is different from that of other signal group. By repeating sets of inverted and non-inverted signal groups, the time length of each set is averaged, and hence, data processing can be made more efficient.

摘要： An optical reader which has a light emitting element, a photodetector, a light emitting side lens for converging a light emitted from the light emitting element to a surface to be detected, and a photodetecting side lens for converging a light reflected on the surface to be detected to the photodetector, wherein the light emitting side focus point focused at the light emitting element by the light emitting side lens is set at a position separated from the lens farther than the photodetecting side focus point focused at the photodetector by the photodetecting side lens. Thus, the adverse influence of a regular reflection light can be prevented in a small-sized structure and a detecting accuracy can be enhanced without decreasing the light detecting efficiency of the optical reader.

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.
