Abstract: A daylight loader cover device adapted to cover the opening of the loader compartment of a photographic printing machine including a perimetric open frame having the same configuration and adapted to be mounted over the opening of the loader compartment. The rear opening in the frame is covered by a light-impervious curtain having a rear passage adapted to be opened and closed. The front opening of the frame is closed by a light-impervious front cover having at least one, and preferably two, sleeve appendages projecting from, and opening through the front cover. The sleeve appendages are provided with elastic cuffs and are adapted to be inverted so that they will receive the arms of the operator and permit the operator's hands to extend into substantially every portion of the antechamber between the front cover and the rear curtain, as well as to permit the operator's hands to extend and operate freely within the loader compartment of the photographic printing machine.
