    摘要： A device for holding film strips and the like in proper position on spiral reels or the like such that the film will be held onto the reel in proper spaced relation to permit the flow of the developer about the film for development thereof. The device includes a longitudinally extending body having a transverse dimension which will permit the device to extend across the width of the film and thus the corresponding spiral reel to contact the edges of the film and hold the same against the spirally formed elements of the reel. The device is designed to lock into the reel between the spiral elements thereof and may be used for full or partial strips of film.

    摘要： A film and print processing apparatus comprises a cylindrical tank and a plurality of cylindrical reels having progressively smaller diameters for coaxial mounting within the tank. A film track is disposed helically, longitudinally or circumferentially about each reel and is operative as a guide for winding a film about the reels and as a spacer for holding the film away from the surface of the reels. Exposed photographic sheets are positioned within the reels for print processing.

    摘要： An improved wet type developing apparatus which can accurately and positively develop a sheet or roll of copying paper at a high speed. The apparatus is provided with means for guiding the copying paper disposed within a reservoir for developer and adapted to attract and hold the copying paper thereto to thereby guide the same so that the copying paper may have the latent image thereon developed by a stream of sufficiently stirred developer providing a high developing effect. Subsequently, the copying paper held by the guide means can be readily released by the loss of attraction in the guide means or forcedly taken off the guide means by the developer flowing out of the guide means, whereby the discharge of the developed paper can be effected simply and positively without any undesirable deformation formed in the copying paper.
