Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
66 words
An absolute position encoder for outputting a position data as an absolute data, comprising: a code member having an absolute code pattern and an incremental code pattern; a counter for counting incremental pulses extracted from the 'incremental code pattern, said counter presetting an absolute position data extracted from the absolute code pattern; and an output circuit for outputting contents of said counter as the absolute data.
Claim 2
Dependent Claim
66 words
An absolute position encoder for outputting a position data as an absolute data, comprising: a code member having an absolute code pattern and an incremental code pattern; a counter for counting incremental pulses extracted from the 'incremental code pattern, said counter presetting an absolute position data extracted from the absolute code pattern; and an output circuit for outputting contents of said counter as the absolute data.
Claim 3
Dependent Claim
25 words
An absolute position encoder according to claim 1, wherein the position data is a rotational position data, and said code member is a rotary disk.
Claim 4
Dependent Claim
27 words
An absolute position encoder according to claim 1, wherein the position data is a linear position data, and said code member has a linearly extending code pattern.
Claim 5
Dependent Claim
27 words
An absolute position encoder according to claim 1, wherein a code pattern taken partly out of the absolute code pattern is used as the incremental code pattern.
