    • 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.
    • 提供了一种包括固定挡板(31),可移动挡板(32)和屏蔽板(33,33')的照相停止单元(80)。 多个孔(32a,32d,32d')形成在可动止挡板(32)中。 在单目摄影中,可动止挡板向下移动,固定挡板的中心止动件(31a)打开,并且进行眼底的单目摄影。 在立体摄影中,可动止挡板向上移动,中心止动件(31a)关闭,在该状态下,屏蔽板(33,33')移动到打开位置或关闭位置,孔(32d,32d' )用于立体摄影被交替地打开,并且进行眼底的立体摄影。 在这种结构中,可以以简单的结构高速进行单目摄影和立体摄影,因为可以高速切换摄影停止的孔。
