Abstract

PURPOSE:To move plural lens groups integrally during focusing and independently during zooming by providing regulating members such as cam grooves respectively to a moving member for focusing and a moving member for zooming. CONSTITUTION:Double helicoid mechanisms are disposed between the inside and outside barrels of a stationary barrel 1 to provide a lens barrel member, and a focusing cam groove 5-1 is provided to a focus control ring 5 held to the helicoid male 3. A focus correcting cam groove 6-1 and a guide groove 7-1 are provided respectively to a focusing ring held to the barrel 1 and a zoom ring 7, and the positions of lenses are controlled by the positions where they intersect with the cam grooves of relatively moving another members. Hence, at the time of zooming, the respective group lenses are moved separately, and at the time of focusing, they are moved in one body, whereby the same lenses are moved in different modes in accordance with purposes.
