Abstract: A virtual displaying device used on a telescopic sight includes a sleeve sleeved around an eyepiece portion of the telescopic sight, a virtual assembly and a fixing portion for fixing the sleeve and the virtual assembly to the eyepiece portion. The virtual assembly includes a housing, a virtual member and a displaying screen both received in the housing. Light emitted from the displaying screen passes through the virtual member to be zoomed, shifted and then projected, together with light of the eyepiece, near distance of eye relief of the telescopic sight so that a shooter can simultaneously and clearly see both the target inside the eyepiece and contents displayed on the displaying screen. The present structure above can allow the shooter to obtain important shooting information while aiming at a target and greatly improve the efficiency of the telescopic sight.

Abstract: A sensing and adjustment system for a telescopic sight includes a plurality of sensing portions, a plurality of driving portions and a central controlling portion respectively fixed to a main body of the telescopic sight, a setting portion, a displaying portion, a plurality of fixing portions, a plurality of transmitting portions each fixed to a corresponding adjusting knob. Each sensing portion includes an angle position sensor and a gear and is configured to perceive a rotation angle of the corresponding adjusting knob and then transmitted to the central controlling portion. The fixing portion fixes the sensing portions and driving portions to the main body and close to their corresponding adjusting knob so that the gear of the sensing portions and driving portions is meshed with a corresponding gear of the transmitting portion.
