Abstract: A battery receiving mechanism includes a battery chamber which receives a battery and a conductor which is connected to one terminal of the battery. A biasing member biases the battery in a direction to connect the terminal of the battery to the conductor. An opening is provided in the wall of the battery opposite the first terminal of the battery to expose the first terminal to the outside.

Abstract: A battery receiving mechanism includes a battery chamber which receives a battery therein and a conductor which is connected to one terminal of said battery. A biasing member biases the battery in a direction to connect the terminal of the battery to the conductor. An operating member moves the battery to disconnect the terminal battery from the conductor against biasing force of the biasing member upon application of an external force.

Abstract: A camera having upper and lower guide rails for guiding a film and a photographing aperture provided between the upper and lower guide rails which defines an image area. A film cartridge compartment and film spool compartment are provided on opposite sides of the photographing aperture, and a mechanism for varying a size of the image area between a large size defined by The photographing aperture and a small size. The camera further includes a first element on which the guide rails and photographing aperture are located, and a second element on which the film cartridge compartment, the film spool compartment and an opening at least as large as the photographing aperture are located. The image area size varying mechanism is provided on the first or second element. The first and second element are secured to each other with the image area size varying mechanism positioned therebetween.
