    摘要: An encoder for measuring devices having a code plate (10) including binary grating patterns arranged in a given regular fashion and forming a first scale, a linear sensor (14) Including photodiode elements (16) arranged with fixed intervals and forming a second scale disposed in parallel with the code plate (10), and processor means (20) for absolute-interpolating one pitch of the first or second scale on the basis of reading data or information (RI) obtained from the linear sensor (14) corresponding to a relative position of the patterns (12) to the elements (16). When the number of the scale divisions of the first scale within a fixed range is N, the number of the scale divisions of the second scale is N + 1. Accordingly, when the first scale is a main scale, the second scale is a vernier scale. The processor means (20) detects a phase inverting point (X) corresponding to the interpolation point (X) on the basis of the reading data (RI). The processor means (20) performs the absolute Interpolation by detecting the phase inverting point (X).

    摘要: An encoder device is characterized by comprising a code plate (1) which is divided into a plurality of blocks (N 1 ,..., Np, .., N n-1 , N n ) along the longitudinal direction, in each of which is encoded address information consisting of code sequences arranged in a row along the longitudinal direction and representing the absolute address of the respective blocks; a line sensor (4) having a plurality of sensor elements arranged in a row for reading the information stored in the code plate; and means (6) for processing an electric output signal from the line sensor (4) to read the block address.

    摘要: An encoder has an optical measuring part establishing a vernier relationship between a code plate (1) and a line sensor (5), and counters (12,17) for obtaining a coarse reading from time serial output signals of the line sensor (5) and a fine reading from the vernier relationship. Correction data including a change component in a magnification of a lens system (4) is obtained from a counter (23). The correction data and the fine reading are supplied to a converting circuit (13a) to provide a corrected fine reading.
