摘要： An encoder includes scale and detection head. The detection head includes light source (transmitting unit) and light-receiving unit (receiving unit). The light-receiving unit includes light-receiving surface (receiving surface) and converts light received at the light-receiving surface 50 into differential detection signals with two phases and outputs the same. The light-receiving surface includes element array group including four element arrays provided in a parallel manner along an orthogonal direction, with each element array including a plurality of light-receiving elements (receiving elements). The plurality of element arrays in the element array group are disposed at positions where the sum of: (i) a distance in the orthogonal direction from a reference position to a positive phase signal element array; and (ii) a distance in the orthogonal direction from the reference position to the negative phase signal element array, is the same for all the phases of the at least two phases.

摘要： In a length measuring device with a measuring transducer system, the curve of two sinusoidal test signals is dependent on the longitudinal movement of the measuring transducer system. An interpolation circuit delivers two high-resolution rectangular pulse sequences F1, F2 corresponding to the interpolated sinusoidal voltages and offset by 90.degree., to an evaluating circuit. To achieve a high-resolution at low speeds of travel and a low-resolution at high speeds, two rectangular pulse sequences S1, S2 or G1, G2, offset by 90.degree. and giving a low-resolution, are additionally derived at the interpolation circuit. A control logic circuit 19 monitors the test voltages for attainment of a certain value of the longitudinal movement per unit time or speed of travel. The control logic circuit lets only the low-resolution rectangular pulse sequences through to the evaluating circuit when this value is exceeded, while it lets the high-resolution rectangular pulse sequences with the low-resolution rectangular pulse sequences when this value is not reached.

摘要： An electronic up-down counter system including a directional discriminator for accepting input pulses and for generating sequences of pulses which represent up-count and down-count signals. The count signals are applied to a reversible up-down counter having separate inputs for up-count pulses and down-count pulses. The directional discriminator is embodied in a read-only memory (ROM), which accepts the source input pulses to be counted and several inputs having predetermined phase relationships with the source pulse train. The ROM determines from the phase relation whether the count is up or down and generates the appropriate output pulse sequence for application to the reversible up-down counter. The ROM may be logically adapted to be sensitive to a change in sign when the up-down counter passes through a "zero" count.
