Abstract

PURPOSE: To increase the precision of encoder and to obtain desired representative value, by removing arbitrary code semi-group from the gray code in m-bit and by obtaining desired number of division with the formation of the encoder hole.
CONSTITUTION: When the gray code C having 32 sets of the number of divisions in 5-bit is changed into the gray code C-4 having 28 sets of the number of division, (table 40), it is formed by removing one code semi-group corresponding to 26 to 29 of the decimal number A from the code C. to the original m-bit, that is the gray code of 2m for the number of division, when the number of division of the gray code after removing the code semi-group is taken 2m-4k (where: K is the number of code semi-group before removal and 0<K<2m-3-1), then the number of division is shown in table 50 and desired number of division, such as, 60, 100, 200, 360 and 1000 can be obtained to respective m value. When the detector 45 moves relatively to the encoder hole 40 placed on the encoder plate along the direction of scanning 49, the detection signal 51, or the rectangular waveform 52 can be obtained by shaping this
