新案登録請求の範囲第(1)項に記載の機構。[Scope of Claim for Utility Model Registration] (1) A distance measuring light beam traveling from the subject side to the line sensor, during its optical path, after passing through the observation optical system and reaching the line sensor, there are multiple parallel light beams. At the same time, the imaging position of the divided beam is shifted back and forth in the optical axis direction of the line sensor, and the focusing operation is performed while comparing and controlling the output signal of the line sensor according to the contrast and blurring of the image of the divided beam. The automatic focus adjustment mechanism includes a cylindrical concave lens, whose cylindrical axis direction is optically aligned with the longitudinal direction of the line sensor, during the optical path of the ranging light beam, after passing through the observation optical system and reaching the line sensor. An automatic focus adjustment mechanism for a microscope, characterized in that the automatic focus adjustment mechanism is interposed so as to coincide with each other. (2) The mechanism according to claim 1, wherein the cylindrical concave lens is interposed in the optical path of the distance-measuring light beam at a position after the light beam is divided.
