Abstract
An underwater still camera is disclosed having a watertight body with a back-loadable light-tight chamber, a lens, a shutter, a cocking lever for bringing the shutter to its cocked position, a push rod for releasing the shutter. Preferably the shutter, the cocking lever and push rod are all disposed outside the camera body. A retaining pawl is slidably and pivotally mounted inside the camera body and is cooperable with a toothed wheel carried by the transport spindle for blocking the rotation thereof under the control of a rotatably mounted intermediate spindle carrying sprockets engageable with perforation carried by a film and at least one stop or ratchet tooth cooperable with the retaining pawl. This arrangement permits use of a single film cartridge in an underwater camera originally adapted to receive a film pack.
