    • In a lens mounting mechanism, by rotating a ring member through touching lugs of the ring member and aligning grooves of a base member and recesses of the ring member in the circumferential direction, and then inserting a lens barrel into a hole portion, the lens barrel is moved to the hole portion without being interfered by projections of a barrel mounting member, so that the lens barrel can be inserted into the hole portion until a flange portion abuts against an opening end surface. Then, by touching the lugs of the ring member and rotating the ring member to displace the recesses from the grooves of the base member in the circumference direction, the projection of the barrel mounting member is locked by the ring member and the barrel mounting member is fixed to the base member, so that the lens barrel can be mounted to the apparatus body.
    • 在透镜安装机构中,通过使环形构件通过接触的环形构件和基部构件的对准槽和环构件的凹部沿圆周方向旋转环形构件,然后将透镜筒插入孔部中,使透镜筒 被移动到孔部分而不被筒安装构件的突起干扰,使得镜筒可以插入孔部分中,直到凸缘部分抵靠开口端面。 然后,通过接触环构件的凸耳并旋转环构件以沿圆周方向从基构件的凹槽移位凹部,筒安装构件的突起被环构件锁定,并且筒安装构件 固定到基部构件上,使得镜筒可以安装到装置主体。

    • Each shading plate comprises a rotating shaft and a driving shaft arranged vertically. First divided shading plate is loosely fitted to and supported by (not adhere to) the rotating shaft and rotates around the shaft. Second divided shading plates are fixed to the rotating shafts and rotate by rotating movement of the shafts. A driving shaft is connected longitudinally to (not adhere to) an edge of the first divided shading plate and supply power to rotate the first divided shading plates. Recesses are formed at the center of upper short side and at the center of lower short side of the first divided shading plate and the first divided shading plate and the second divided shading plates which form one and the same shading plate are so constructed that their short sides are overlapped each other.
    • 每个遮光板包括旋转轴和垂直布置的驱动轴。 第一分开的遮光板松动地安装并支撑(不粘附)旋转轴并围绕轴旋转。 第二分割的遮光板固定在旋转轴上并通过轴的旋转运动而旋转。 驱动轴纵向地连接到第一分开的遮光板的边缘(未附着),并且供应动力以旋转第一分割的遮光板。 凹部形成在第一分割遮光板的上短边的中心和下短边的中心,并且形成同一遮光板的第一遮光板和第二遮光板被构造成使得它们的短 侧面相互重叠。
