摘要： PROBLEM TO BE SOLVED: To solve the problem that it is difficult to make high resolution due to the limit of refining a code pattern or the like on a code plate.
SOLUTION: The optical encoder consists of a light source part, a light receiving part, and the movable code plate 4 located between the optical paths of both the parts, in which the well known pattern for detecting an absolute position to detect the information of the absolute position of the code plate 4 is formed on an outside track T2 on the code plate 4, and a phase type diffraction grating is formed on an inside track T1. Then the relative position information of the code plate 4 is detected based on the interference beam of two diffraction beams diffracted with the phase type diffraction grating and therefore detection with high resolution can be done from the combination of both the information.

摘要： PROBLEM TO BE SOLVED: To provide an absolute position encoder that can set a traveling speed or a rotary speed in power failure according to the configuration of each shaft, usage, and setup changing work in use by mounting to a machine apparatus having at least one operation shaft, and can detect up to high-speed rotation without consuming an unneeded current as an entire machine apparatus.
SOLUTION: An allowable rotational speed determination section 13 in power failure generates a count clock frequency switching command 18 for specifying a count clock frequency corresponding to speed that may be moved or rotated in power failure by receiving an allowable rotational speed in power failure to be inputted from the outside via a reception circuit section 11, and a serial communication data input section 12. As a result, a count clock signal at a specific frequency is generated by a count clock frequency switching circuit 15, and a counting section 16 on power failure performs counting action in synchronization with the count clock signal, thus miniaturizing a battery and extending its life.

摘要： A photoelectric rotary encoder includes a light source that emits a light beam, a returning section that returns the emitted light beam to a direction opposite to an emitting direction of the beam, and a photodetector that is disposed on a substrate on which the light source is disposed and that detects the returned light beam via a disk having a detection pattern section. The photoelectric rotary encoder detects rotational displacement of the disk based on the detected returned light beam. In this photoelectric rotary encoder, an optical element that lets a stray beam component of the light beam from the light source escape via a side surface of the optical element, is disposed in front of the substrate on which the light source and the photodetector are disposed. The optical element covers the substrate and integrates the optical element and the substrate.
