Abstract
A single-use instant camera includes a main body, having the taking lens and the shutter mechanism. A film unit containing chamber is formed in the main body, and contains a plurality of instant film units stacked on one another. The containing chamber is opened toward a rear and has a front wall. An exposure aperture is formed in the front wall, and receives the image-recording portion of the film units, to provide the film units with exposure to light entered through the taking lens from an object to be photographed. A front cover is disposed in front of the main body to cover the main body. An advancing claw mechanism is disposed between the front cover and the main body, and advances an exposed one of the film units to be exited. A flash device is disposed between the front cover and the main body, and applies illuminating light to the object. A back lid is disposed behind the containing chamber, is engaged with the main body, and closes the containing chamber. A pressure plate is mounted on the back lid, and presses the film units toward the exposure aperture.
