Abstract
A Brownie camera is loadable with a 120- and 220-type roll photo film. The 120 type includes light-shielding backing paper overlaid on the entirety of the photo filmstrip, unlike the 220 type. An exposure aperture is formed in a camera body, and disposed between a photo film supply chamber and a photo film take-up chamber, for exposing the roll photo film. A pair of rails are disposed along respective two edges of the exposure aperture extending horizontally, and contact sides of an emulsion surface of the roll photo film. A pressure plate contacts a back of the roll photo film to position the roll photo film on a rear of the exposure aperture, and is disposed behind the exposure aperture to define a photo film passageway between the pressure plate and the rails. An external selector wheel is disposed outside the camera body, for selecting one of the 120 and 220 types. A mechanism for moving the pressure plate is actuated by a shift of the selector wheel, for moving the pressure plate toward or away from the rails. The passageway is set at a wide space size when the 120 type is selected, and at a narrower space size when the 220 type is selected.
