Appeal No. 1997-3919 Application 08/392,160 an observing optical system for observing the object with a reflection light of the illumination light irradiated to the object by said illumination optical system; a focus index projecting optical system for projecting a light of focus index to the object to be observed; means for restricting illumination luminous flux by intermittently shutting said illumination light, which is provided in said illumination optical system; means for restricting luminous flux of focus index by intermittently shutting said focus index light, which is provided in said focus index projecting optical system; and means for detecting focus distance and direction by synthesizing synchronous timing signals of said illumination luminous flux restricting means and said focus index luminous flux restricting means, wherein the position of the object to be observed is changed based on the signal detected by said focus detecting means.
