    摘要: An encoder (100) comprises a first substrate (125) comprising a point light source (121) that emits light onto reflective slits formed on a disc (110) and a light-receiving element (122a, 123a) that receives light emitted from the point light source (121) and reflected by the reflective slits, a second substrate (130) onto which the first substrate (125) is mounted, a lustrous connecting portion (180) configured to electrically connect the first substrate (125) and the second substrate (130), and a covering material (190) configured to cover the connecting portion (180) in the manner that the point light source (121) and the light-receiving element (122a, 123a) are exposed.

    摘要: An encoder (100) includes a track (SA1, SA2) having optical effecters arranged to have an absolute pattern in a measurement direction (C), a light source (121) configured to emit diffusion light to the track (SA1, SA2), and a light receiving array (PA1, PA2) configured to have light receiving elements arranged in the measurement direction (C) and to receive light reflected or transmitted by the track (SA1, SA2) . The light receiving elements fall within an area (DA) which is positioned corresponding to an area between the optical effecters and to which the light reflected by the track (SA1, SA2) dose not reach.
