Abstract
An electronic distance meter includes a sighting telescope having an objective lens for sighting an object; a reflection member provided behind the objective lens, wherein the reflection member is positioned so as to be eccentric with respect to an optical axis of the objective lens; and an optical distance meter which includes a light-transmitting optical system for transmitting a measuring light via the reflection member and the objective lens, and a light-receiving optical system for receiving a portion of the measuring light which is reflected by the object, subsequently passed through the objective lens, and not obstructed by the reflection member.
