Abstract
In a sight scope device, a sleeve-like body is provided with a translucent mirror and a light source. Light emitted from the light source is reflected by the translucent mirror and proceeded toward an eyepiece side so as to served as an aiming point. A shield member interposed between the translucent mirror and the light source and having a plurality of through-holes is provided on the body. These through-holes have different areas, respectively, with each other. A movement of the shield member on a plane which is generally perpendicular to an axis of the body causes one of the through-holes to be selectively arranged or appeared on a line connecting the light source and the translucent mirror. The one of the through-holes is selected depending on a distance to a target.
