摘要： A rotating shaft mechanism includes a first connecting portion, a second connecting portion, a central shaft rotatably connected to the first connecting portion and the second connecting portion, and an adjusting unit disposed on the central shaft. The adjusting unit includes an adjusting ring disposed around the central shaft, a first washer disposed around the central shaft and configured to generate a force to the first connecting portion or the second connecting portion. A position of the adjusting ring with respect to the central shaft is axially adjustable for adjusting the force so that the first connecting portion or the second connecting portion is rotatable or fixed relative to the central shaft.

摘要： A lens assembly is configured to be disposed under a cover glass, in a gap region and outside a display region, including a plurality of lenses, a reflector and an image sensor. The lenses, the reflector and the image sensor are sequentially arranged from an object side to an image side along an optical axis. One of the lenses is adjacent to the object side, has a minimum diameter of clear aperture, and has an outer circumferential portion which is non-circular. The lens assembly satisfies at least one of following conditions: BFL≥VL and BFL≥0.6×DL where BFL is a back focal length of the lens assembly, VL is a minimum side length of the image sensor, and DL is a diagonal length of the image sensor. A lens device includes a cover glass, a case, a display panel and the lens assembly.

摘要： A compensating mechanism includes a base, an adjusting unit, an adjusting cap and a stop unit. The adjusting unit is disposed on the base. The adjusting cap is configured to move the adjusting unit with respect to the base so as to form a first circumferential movement range. The stop unit includes a sliding element and a limiting element, wherein the limiting element includes a movement region, and the adjusting cap is configured to move the sliding element along the movement region so as to form a second circumferential movement range. A sum of a first central angle corresponding to the first circumferential movement range and a second central angle corresponding to the second circumferential movement range is a fixed value. A sight is provided to include a main body, an objective unit, an ocular unit, an inner lens barrel and the compensating mechanism.
