Claims

[Scope of utility model registration request]

In a lens lens frame, a lens system is constructed by incorporating a plurality of lenses inside, aligning their optical axes and maintaining them at predetermined intervals. Each lens is fixed one by one, and a suitable number of lenses extending outward in the radial direction is used. A ring-shaped sub-lens frame having an adjustment rod, a through hole into which all of the above-mentioned sub-lens frames are loosely fitted, and a through-hole through which the adjustment rod loosely passes, and a stepped portion that positions the above-mentioned sub-lens frame in the axial direction. 1. A lens frame comprising: a primary lens frame having a main lens frame; and a secondary lens frame for adjusting eccentricity of each lens, the latter being fixed to the primary lens frame.
