发明名称 Waist level viewfinder
摘要 A waist level viewfinder for a camera arranged to permit direct observation from above a focusing plate of the image of an object formed on the focusing plate. The viewfinder includes a first light shielding tubular member which is attachable to and detachable from the camera and a second light shielding tubular member which is slidable relative to the first tubular member and which is provided with an eyepiece. The eyepiece is pivotally mounted so as to be capable of being retracted out of the viewing path of the reticle plate. The viewfinder is thus arranged to provide improved light shielding characteristics when it is in use and to have improved portability when not in use while also facilitating diopter correction.
