The second lens group consists of sequentially from the enlarging side two or three positive lens elements, first and second cemented lenses, a negative lens element, and a positive lens element. Both of the first and second lenses consist of cemented biconvex lens element and negative lens element. During a zooming operation from the maximum focal length edge to the minimum focal length edge, the first lens group shifts from the enlarging side to the reducing side on the maximum focal length side and shifts from the reducing side to the enlarging side on the minimum focal length side. On the other hand, the second lens group monotonously shifts from the enlarging side to the reducing side during the zooming operation.

Abstract: A mechanism, provided in a camera with a cartridge compartment to which a film cartridge having a light-intercepting door is loaded, which opens the light-intercepting door only if a cover of the cartridge compartment is closed. The mechanism has a film detecting lever which detects if a film is fed out of the film cartridge or not; and a switching lever, for opening and closing the cover in association with an opening and closing movement of the light-intercepting door of the film cartridge, whose operation is controlled by a position of the film detecting lever. That is, if the film detecting lever detects that the film is fed out of the film cartridge, the film detecting lever prevents the switching lever from being unlocked from the compartment cover, while if the film detecting lever detects that the film is not fed out of the film cartridge, the film detecting lever allows the switching lever to be unlocked from the compartment cover.
