ABSTRACT:
In a film holder, a slot for receiving a marking member is made in a bottom flap of the film holder along the inner edge of the bottom flap. The slot is shaped such that when the marking member is inserted into the slot, a part of the marking member is opposed to a photo sensitive material and another part of the member is projected from the slot above the inner edge. Therefore, the marks or characters can be put on the photo sensitive material through the exposure to a photographing light.
