摘要： To provide a lens select device in which an iris image pickup function may be incorporated into a portable information terminal at low cost.In a lens support member 34, a small gear 51 is formed at one end part of the lens support member, and a lens-housing boss part 53 and a lens-housing boss part 54 are juxtaposed at the other end part. By turning the small gear 51, the first lens or the second lens is aligned with a predetermined position. An operation part 59 is provided. When the operation part 59 engages with the small gear 51 and turns the same, the operation part 59 switches the lens which is aligned with the predetermined position to the first lens or the second lens. Preferably, the operation part 59 is an arcuate member which turns about a position, which is different from a rotational center of the small gear 51, and it is an inscribed gear 59 having teeth formed in the inner peripheral surface, which are in mesh with the small gear 51.

摘要翻译： 为了提供可以以低成本将虹膜图像拾取功能结合到便携式信息终端中的透镜选择装置。在透镜支撑构件34中，在透镜支撑构件的一个端部处形成小齿轮51，并且 透镜壳体凸台部分53和透镜壳体凸台部分54在另一端部处并列。 通过转动小齿轮51，第一透镜或第二透镜与预定位置对齐。 提供操作部59。 当操作部分59与小齿轮51接合并转动时，操作部分59将与预定位置对准的透镜切换到第一透镜或第二透镜。 优选地，操作部59是与小齿轮51的旋转中心不同的位置转动的弓形部件，并且是在内周面形成有齿的内接齿轮59，内齿面59与 小齿轮51。
