    • A lens assembly comprises a lens group M and a lens frame 1 for retaining the lens group M. In this lens assembly, the lens frame 1 has an entire circumference support 2b for supporting the rim on the subject side, of each lens M, across the entire circumference thereof, and an end face support 2a for supporting the lens M on the image side. Each lens M comprises a chamfer 3b formed at a rim of a lens surface on the subject side across the entire circumference thereof, and the entire circumference support 2b supports the chamfer 3b such that the entire circumference support 2b is continuous with the lens surface at substantially the same radius of curvature with the lens surface. According to the present invention, there is provided a lens assembly which can reduce size and cost and has stable lens retaining ability.
    • 透镜组件包括透镜组M和用于保持透镜组M的透镜框1.在该透镜组件中,透镜框1具有用于支撑每个透镜M的物体侧上的边缘的整个圆周支撑2b, 整个圆周,以及用于在图像侧支撑透镜M的端面支撑件2a。 每个透镜M包括形成在主体侧的透镜表面的边缘的整个圆周上的倒角3b,并且整个圆周支撑件2b支撑倒角3b,使得整个圆周支撑2b基本上与透镜表面连续 与镜头表面相同的曲率半径。 根据本发明,提供一种可以减小尺寸和成本并且具有稳定的镜片保持能力的透镜组件。
