Inventor: FUJIBAYASHI KAZUO
IPC: G03B13/28
Filed: 1979-06-22
Abstract: PURPOSE: To enable the focusing of the bar-form object extending in the lateral directions and oblique directions by dividing the distance measuring region composed of split prisms to a central part and the peripheral part encircling this and letting the split directions of the image in the respective portions differ with each other.  
     CONSTITUTION: The central part distance measuring region 2 of a focal plate 1 is divided to the central part consisting of a pair 3, 4 of split prisms having the wedge direction parallel to the horizontal line as a boundary line and the peripheral part of torus-form consisting of a pair 5, 6 of split prisms having the wedge direction parallel to the perpendicular line as a boundary line and therefore even if an object is not extending in the vertical directions, its focusing is possible as far as it is extending in the lateral or oblique directions.
