回転板式空気流量センサ。A rotating plate is provided with a return spring force and arranged to block the airflow passage, a light-shielding disc is integrally attached to the rotating shaft of the rotating plate, and a light-shielding disc is arranged around the periphery of the light-shielding disc, respectively. It consists of two sets of light emitting/receiving elements disposed at positions where the optical path is blocked by the front-to-external light disc, and the light emitting/receiving elements are shifted by a half pitch from each other at the positions where the optical path of the light shielding disc is blocked. A slit-like light-shielding pattern is formed, and when the light-shielding disk rotates, pulse wave outputs with different phases are output to the two sets of light emitting/receiving elements, and these pulses are counted to detect the rotational position of the rotary plate.
