Patent attributes
A zoom lens camera includes an optical-element drive mechanism for a photographing optical system, and a zooming-associating mechanism for associating a zooming-associated driven member with a zooming operation to be driven by the optical-element drive mechanism in a ready-to-photograph state, and for releasing the association of the zooming-associated driven member with the zooming operation between the ready-to-photograph state and the retracted state. The zooming-associating mechanism includes three rotational members, and includes a master rotational member and a slave rotational member at opposite ends thereof. Opposed surfaces of two adjacent rotational members include rotation transfer portions engaged with each other at predetermined relative angular positions so as to integrally rotate.
