According to one embodiment, a holding apparatus includes a holding mechanism, a movement mechanism, a measuring instrument, a detector, and a controller. The holding mechanism holds a mobile body. The mobile body is movable through a gap between first and second structure bodies. The first structure body is columnar and extends in a first direction. The second structure body is tubular and is located around the first structure body along a first plane perpendicular to the first direction. The movement mechanism moves the holding mechanism along a circumferential direction around the first direction. The measuring instrument measures a movement amount in the circumferential direction of the holding mechanism. The detector detects a tilt of the holding mechanism in the first plane. The controller operates the movement mechanism and moves the holding mechanism based on a measurement result of the measuring instrument and a detection result of the first detector.

A rotary encoder (1) comprising a housing (2), a shaft (3), a code disk (4) which is attached to the shaft (3), and a reading head (5) which is designed to detect the rotation of the code disk (4) are disclosed herein. The code disk (4) is affixed in the axial position thereof on an axial side by way of an abutment (6), and a resilient element (7, 17, 19) is arranged on the other axial side providing a clamping force for pressing the code disk (4) against the abutment (6). A method for assembling a rotary encoder is also disclosed herein.

A bearing includes a first ring and a second ring capable of rotating concentrically relative to one another. At least one groove is formed on an axial cylindrical surface of the second ring and oriented towards the first ring. The groove is axially delimited by two side edges 50a. The bearing further includes at least one optical sensor mounted on the first ring to emit a beam oriented towards at least one of the side edges of the groove of the second ring, the optical sensor being able to detect axial positions of the side edge.

A double-bearing position encoder has an axle stabilized within a housing via two bearings disposed on opposite walls of the housing. The axle is in communications with a rotating cam. The cam actuates a pulser so as to generate an active pulse at a tissue site for analysis by an optical sensor. The axle rotates a slotted encoder wheel or a reflective encoder cylinder disposed within the housing so as to accurately determine the axle position and, hence, the active pulse frequency and phase.
