    • A focus adjusting mechanism (50) for use in a portable electronic device (100) with a lens module (40) is provided. The lens module includes a lens barrel (42) and a lens barrel holder (44). The lens barrel is threaded into the barrel holder. The focus adjusting mechanism includes a driving member (52), a follower (54) and a transmission rod (56). The driving member has a plurality of circumferential teeth (5242) formed thereon. The follower has a plurality of linear teeth (5472) formed thereon. The linear teeth engage with the circumferential teeth for transforming the rotation of the driving member to the linear movement of the follower. The transmission rod is disposed between the follower and the lens barrel to transform the linear movement of the follower into the rotation movement of the lens barrel relative to the lens barrel holder.
    • 提供了一种用于具有透镜模块(40)的便携式电子设备(100)中的聚焦调节机构(50)。 透镜模块包括透镜镜筒(42)和透镜镜筒保持器(44)。 镜筒被拧入镜架中。 焦点调节机构包括驱动构件(52),从动件(54)和传动杆(56)。 驱动构件具有形成在其上的多个周向齿(5242)。 从动件具有形成在其上的多个线性齿(5472)。 线性齿与周向齿接合,用于将驱动构件的旋转转换成从动件的线性运动。 传动杆设置在从动件和透镜筒之间,以将随动件的线性运动转变成镜筒相对于镜筒保持器的旋转运动。
