Abstract
A peel-apart type instant photographic apparatus using a negative film and a positive sheet. The apparatus has a dark box for developing and accommodating the negative film and positive sheet, or supply, joined together and having a developer spread therebetween. The dark box is removable from the apparatus body and, therefore, easy to clean and handle. When the dark box is not mounted on the apparatus body in predetermined conditions, a printing operation is inhibited to eliminate the waste of negative sheets and positive sheets. A printing operation is also inhibited when the supply is left in the dark box.
