Abstract
An apparatus for adjusting a direction of an illuminating light beam in an ophthalmoscope which contains a photographing device includes a click stop mechanism which click stops rotation of a mirror used to reflect the illuminating light beam so that the light beam is accurately reflected onto a photographic film in the photographing device. A knob is integrally connected to a rotary shaft which is rotatably coupled to a mirror frame so that rotation of the knob rotates the mirror frame, and an interlocking member is fixedly disposed on the rotary shaft and contains a click ball mechanism which selectively engages a hole in an outer frame so that rotation of the rotary shaft is click stopped at a predetermined position.
