PURPOSE: To provide the device which is simple to assemble and permits accurate positioning and holding of the lenses by such things as the formation of the lens- barrel to the construction comprising bisecting the barrel nearly parallel to the optical axis and providing the positioning face which determines the positions of the lenses and others.
CONSTITUTION: The barrel consists of split segments 4a, 4b and has the surface which determines the positions of lenses 1, 2, 3. Its positioning of the lenses is made accurate by elastic pieces 1b, 2b and 3b and the entire part is made to an integral lens assembly by rings 7, 8. Such constitution not only makes assembling easy but also enables the lenses to be accurately positioned and held.
