使用される光学式のロータリーエンコーダに関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to an optical rotary encoder used in servo motors and the like in the fields of measurement and control.

つき説明する。A rotary plate rotated on the detection axis and a reading means for reading the marks attached to the rotary plate detect the (b) of the rotating body.
An encoder that detects positional changes is called a rotary encoder, and its mark reading means include optical, magnetic, and contact types. A conventional rotary encoder will be described below.

た。As shown in Figures 4 and 5, the conventional type has a detection axis (1
) was provided protruding from only one side of the casing (12), so when the motor (rotary encoder (5)) is attached to the rotating shaft such as B1 using the rotating shaft (11),
Since it has a rotary encoder or single-axis structure, it also has the disadvantage that other detectors such as a tacho generator cannot be attached.

。However, the information you want to obtain from the rotating body (rotating shaft) is the rotational position, rotation direction, and rotation speed. Of these, the rotation position and rotation direction can be easily grasped using a rotary encoder, but the rotation speed Although it is possible to perform calculation processing from rotational position information, it is actually difficult to accurately know the rotational speed over a wide range.

用的な価値はきわめて＾まるものと考えた。Therefore, we thought that it would be of great practical value if the rotary encoder could be connected not only to the rotating shaft to be detected, but also to an autopsy device for measuring rotational speed.
