Patent number: 6946649Abstract: A rotary encoder has a disc, a pair of photo-interrupters, an adjusting member, and a shifting controller. The disc rotates around a rotating axis and has slits that are formed circumferentially at given intervals. Each of the photo-interrupters has a light-emitting device and a photo-detecting device opposite one another, and generates two signals with a phase difference. Each photo-interrupter is pivotable around a pivot coaxial with the rotating axis, and is arranged along the circumferential direction of the disc so as to position the slits between the light-emitting device and the photo-detector. The adjusting member contacts the pair of photo-interrupters, and is movable along a shifting direction corresponding to a radial direction of the disc, so as to engage the pair of photo-interrupters. The adjusting member adjusts a relative position-relationship between the pair of photo-interrupters associated with the phase difference.Type: GrantFiled: September 22, 2003Date of Patent: September 20, 2005Assignee: PENTAX CorporationInventors: Yukio Uenaka, Kazuhiro Hattori
