制御回路、 を具備したエンコーダ。[Claims for Utility Model Registration] Slits are formed at a constant pitch on a code plate, a light emitting means and a light receiving means are disposed facing each other with the slits sandwiched between them, and the code is detected based on the light passing through the slits detected by the light receiving means. In addition to detecting the displacement of the plate, the light receiving means scans detection signals of the plurality of light receiving elements in an optical encoder having a configuration in which a plurality of light receiving elements are arranged within one pitch of the slit. , a signal generation circuit that adds scanned signals to generate a phase signal of the code plate; a peak detection circuit that detects the amplitude of this phase signal; and amplitude detection from an amplitude setting signal of the phase signal and the peak detection circuit. The signals are input and the difference between them is 0.
An encoder comprising: a drive control circuit that controls driving of the light emitting means so that the light emitting means is driven.
