Abstract: An auto-process film unit comprising a photosensitive sheet and a positive image sheet, which is bondable to the photosensitive sheet, but is initially separated therefrom by a removable light-proof, anti-adhesive strip, which forms a folded portion between the photosensitive and positive image sheets, and is attached at one end to a wind-up means. This film unit has the advantage that since the photosensitive sheet for production of a negative image and a positive image sheet onto which a corresponding image is transferred are not initially bonded together, processing solution may move freely therebetween, whereby even quality of a produced photograph is ensured.

Abstract: A film unit assembly wherein leaders for removal of exposed film units from a pack are made of lightproof material, are each large enough to cover the photosensitive portion of a film unit, and successive leaders extend between successive film units, and provide lightproof protection of rearward film units when a foremost film unit is exposed. One end of the leader between any two film units is attached to the leading end of one film unit, and the other end of the leader is attached to the trailing end of the other film unit, whereby, when an exposed film unit is drawn out of a pack, the exposed film unit simultaneously draws the leader attached thereto out of the pack, and uncovers the next film unit.
