Claims (1)
形成された円板状光反射板と、この光反射板に所定の光
を照射するとともにその反射光を検知し光電変換する光
送受信部と、この光送受信部の出力信号を信号処理して
所定の速度制御信号を出力する信号処理系とを備えた回
転式信号発生装置において、前記光反射スリットの内の
−又は二部以上に異った幅の光反射スリットを設け、こ
れによって得られる光反射信号から速度制御信号と位相
制御信号とを分離して出力する第１および第２の信号処
理系を併設したことを特徴とする回転式信号発生装置。A disc-shaped light reflecting plate that rotates with a rotating body and has a plurality of light reflecting slits formed at equal intervals, and an optical transmitting/receiving unit that irradiates the light reflecting plate with a predetermined light, detects the reflected light, and converts it into electricity. and a signal processing system that processes the output signal of the optical transmitter/receiver and outputs a predetermined speed control signal, wherein one or more of the light reflecting slits are different from each other. The rotary type is characterized in that it is provided with a light reflection slit having a width of 100 mm, and is provided with first and second signal processing systems that separate and output a speed control signal and a phase control signal from the light reflection signal obtained by the light reflection slit. Signal generator.
