Abstract

PURPOSE: To improve the precision of sighting operation by using a sighting board fitted with a reference point mark and a couple of semicircle fitting rings.
CONSTITUTION: To measure easily the coordinate position of one point in a plane by placing a reference point at the same position and by making use of drawn-out lengths of two thin lins between two fixed points and the reference point, reference point mark 34 is entered in the center and while semicircle fitting rings 31 and 31' for fitting slidable measuring thin lines 32 and 32' are fitted rotatably on center spindle 35 of rotation in common, manually holdable sighting board 33 is provided. Consequently, even when an operator, while holding reference mark 34 in coincidence with measurement, rotates sighting board 33 around its vertical axis 35 and horizontal axis 36, measuring thin lines 32 and 32' are in the measurement plane and on their extension lines, reference mark 34 stays, so that distances between the reference point and the 1st and 2nd fixed points 27 and 27' will never vary. Therefore, sighting board 33 can be placed at right angles to direction 37 in which a picture is projected, so that accurate sighting operation will be performed.
