Support structure for light quantity control unit of lens barrel
摘要：
A support structure for a light quantity control unit of a lens barrel includes a holding frame which holds a light quantity control member; front and rear support members positioned in front and behind the holding frame, respectively; a front guide pin and a front pin support hole formed on one and the other of the holding frame and the front support member, the front guide pin being slidably inserted into the front pin support hole; and a rear guide pin and a rear pin support hole formed on one and the other of the holding frame and the rear support member, the rear guide pin being slidably inserted into the rear pin support hole. The holding frame is supported by the front and rear guide pins and the front and rear pin support holes to be movable between the front and rear support members.
摘要（中）：

用于镜筒的光量控制单元的支撑结构包括保持光量控制构件的保持框架; 分别位于保持框架前后的前后支撑构件; 形成在保持框架和前支撑构件的一个和另一个上的前引导销和前销支撑孔，前引导销可滑动地插入前销支撑孔中; 以及形成在保持框架和后支撑构件的一个和另一个上的后引导销和后销支撑孔，后引导销可滑动地插入后销支撑孔中。 保持框架由前后引导销和前后销支撑孔支撑，以在前支撑构件和后支撑构件之间移动。
