Abstract: A sight includes a main body, an erecting unit and a compensating mechanism. The compensating mechanism includes a fixing unit, a cover and an switching unit. A compensating mechanism for a sight includes a base unit, a transmission unit, an adjusting cap, a movable unit and a lock unit. The adjusting cap is located in a first position when the adjusting cap is locked by the lock unit. The adjusting cap in the first position can be rotated in a second direction or in a third direction opposite to the second direction when the lock unit is moved in a first direction to release the adjusting cap. The adjusting cap stops in a second position when the adjusting cap is rotated in the third direction so that the movable unit is propped against an end of a groove of the adjusting cap.

Abstract: A lens cover module includes a rail member, a lens cover movably mounted on the rail member, a first driving device, and a second driving device. The lens cover reciprocates between a first position where the lens cover covers the lens, and a second position, where the lens cover uncovers the lens. The first driving device moves the lens cover from the first position to a third position, and moves the lens cover from the second position to a fourth position. After the first driving device, the second driving device keeps moving the lens cover to the second position from the third position, or moving the lens cover to the first position from the fourth position.

Abstract: A sight includes an objective barrel and a dust cap connected to the objective barrel. The dust cap includes a main body, a cover, a first flexible element, and a second flexible element, The cover is connected to the main body. The first flexible element is connected to the main body and includes an inner surface. The second flexible element is disposed in the first flexible element and includes an outer surface wherein the outer surface of the second flexible element contacts the inner surface of the first flexible element.

Abstract: A telescopic sight includes a main body, a positioning-adjustable member, and a sunshade hood. The main body includes a lens chamber and an enclosure, and the enclosure covers the lens chamber and includes at least one slot. The positioning-adjustable member is movably disposed in the slot. The sunshade hood includes at least one hole corresponding to the positioning-adjustable member, and the positioning-adjustable member is partially disposed in the hole.

Abstract: A lens cover module includes a rail member, a lens cover movably mounted on the rail member, a first driving device, and a second driving device. The lens cover reciprocates between a first position where the lens cover covers the lens, and a second position, where the lens cover uncovers the lens. The first driving device moves the lens cover from the first position to a third position, and moves the lens cover from the second position to a fourth position. After the first driving device, the second driving device keeps moving the lens cover to the second position from the third position, or moving the lens cover to the first position from the fourth position.
