Abstract

An instant camera is used with a photo film pack, which includes plural photo film units of a self-processing type. Each of the photo film units includes a processing solution pod for containing processing solution. There is an exposure surface which is exposed by photographic subject light and on which the processing solution is spread for processing. A case contains a stack of the plural photo film units. A photo film outlet causes the photo film units to exit. The instant camera has a pack chamber loaded with the photo film pack. An exposure aperture is formed to open in one face of the pack chamber, and sets the exposure surface of the photo film units inside the photo film pack. A set of first and second spreader rollers press and convey an exposed one of the photo film units advanced from the pack chamber, and squeeze the solution pod to spread the processing solution on the exposure surface. A spread control wall is disposed between the photo film outlet and the spreader roller set, pushes the photo film unit advanced from the photo film outlet, and controls distribution of the processing solution on the exposure surface.
