摘要: A code plate (6) of an incremental encoder is fixedly mounted to a first rotor (4) which rotatably supported on housing (1); small-diameter portion (4a) and large-diameter (4b) are formed the outer peripheral surface rotor; furthermore pair engaging projections (17a/17b) both sides clearance groove (16) in portion. rotating ring inside bottom housing; driven gear through range about 90 degrees, shield erected position corresponding gear. Five photo-interrupters (13a-13e) arranged astride path rotation ring, so that can be detected by ON/OFF operation photo-interrupters. On intermediate (14) supported, constant mesh with provided tooth second portion, 45 degrees apart from each other. The faces rotor, while whereby turned during one thus turning two teeth
