Abstract
A panoramic camera utilizes a rotating drum to mount the lens and front and rear vertical slits defined by the drum pass a narrow band of light through the lens and onto a cylindrically formed film sheet held at the rear of the drum by a frame. A small DC reversible electric motor drives the drum through friction wheels rather than gears to avoid play and backlash, and sweeps the drum through its exposure cycle, immediately upon the termination of which it reverses direction to return to the starting position.
