A cover having an exposure aperture is hinged to the holder housing and pivotally opened for loading the sheet film pack. When the cover is closed, the cap is released from the lid and the pack housing, and the cap is held in the holder housing. By sliding the lid out of and then back into the holder housing, the topmost sheet film unit is positioned in the exposure aperture and pressed by the lid into proper position. After photographing, by sliding lid out of and then back into the holder housing, the sliding tray is moved relative to the holder housing together with the lid, so that the exposed sheet film unit is fed into the bottom side of the pack housing through the film recovery mouth. A latch mechanism for preventing wrong motion of the lid and the sliding tray is incorporated in the film pack hold…
