摘要： An angle measuring device comprises a base, a telescope seated thereupon for rotation about an axis, a graduated circle having a line division, a micrometer for subdividing said line division, and photoelectric scanners for detecting angular values from said line division and from said micrometer. A graduated plate provided with a reticle is located in said telescope. Said reticle has a zone limited by two line marks which are arranged in parallel and symmetrically to and on either side of one of the reticle lines. Said two lines are spaced from said reticle line by a width which is at least double the size of one division interval of the graduated circle line division.
