Abstract:
There is provided a photographic stop unit (80) comprising a fixed stop plate (31), a movable stop plate (32), and shield plates (33, 33′). A plurality of apertures (32a, 32d, 32d′) is formed in the movable stop plate (32). In monocular photography, the movable stop plate moves downward, a center stop (31a) of the fixed stop plate opens, and monocular photography of the ocular fundus is performed. In stereo-photography, the movable stop plate moves upward, the center stop (31a) is closed, the shield plates (33, 33′) move to the open position or the closed position in this state, the apertures (32d, 32d′) for stereo-photography are alternately opened, and stereo-photography of the ocular fundus is carried out. In such a configuration, monocular photography and stereo-photography can be carried out at high speed in a simple configuration because the apertures of the photographic stop can be switched at high speed.
