Abstract
PURPOSE: To eliminate the need for adjustment at the assembling and make assembling easy by providing an aligning means for aligning the optical axes of lenses with each other, an inter-lens spacing defining means, a sealing means and a coupling means through intergral molding and holding the extra precision machine accuracy at the integral molding.
CONSTITUTION: A movable lens-barrel 3 is helicoid-fitted to the outside circumference of the stationary lens-barrel 1 which is screwed to the lens-barrel mounting plate 2 of the camera body by means of plural mounting arms 1a. A focus lens 5 is fixed and held in cooperation to the focus operating barrel 4 fixed and fitted to the outside circumference of said lens-barrel. Other two sheets of plastic lenses 10 and 20 are mounted in the stationary lens-brallel 1. A ring part 11 which makes close fitting to the outside circumference of the front surface of the lens 20 provided to the lens 10 through integral molding is integrally molded and this ring part 11 is so formed as to abut against the flange part 22 provided through integral molding on the outside circumference of the lens 20. Alignment of optical axes is accomplished by closely fitting the lenses 10 and 20 into the ring parts 11 and 12, whereby dust-proofing into the air spacing between both lenses is effected. The abutting holds the air spacing at the specified value.
