Abstract
Abstract A negative carrier which holds an intermediate portion of a negative film from opposite sides is mounted upon a base plate having an opening for printing. The carrier brings the printing opening formed in the negative film into registry with the opening in the base plate having locating protrusions. The carrier can be moved into the opening in the plate from any one of plural different directions. During this movement, the carrier is guided and allowed to assume only a given posture by the protrusions. Thus, the film is inserted also in the same posture. Consequently, ends of the film are prevented from inadvertently being inserted into the opening in the plate, which would otherwise hinder the work.
