Abstract: A compact print making device by which a desired imprint figure can be made easily in a short time. This print making device employs a resin seal face member, a part of which receives light having a wavelength within a predetermined range and thus is put into a state different from the state of the remaining part thereof and is adapted to have an uneven face formed by being acted upon by a predetermined fluid. The resin seal face member and an original picture representing an imprint figure are arranged with the original picture just in back of the resin seal face member. Imprint figure information representing the imprint figure shown in the original picture is taken in by an information reading mechanism. A negative film making unit is driven according to the imprint figure information so as to produce a negative film. Then, the produced negative film is carried to an irradiating position. Subsequently, a light irradiating unit irradiates the resin seal face member with light through the negative film.

Abstract: Methods and apparatus are provided for producing a set of color correction masks on a single piece of masking film, or a set of color separation negatives on a single piece of separation negative film. The set of masks or set of negatives may be exposed so that each entire set may be developed simultaneously under identical development conditions. This is accomplished by determining a development time which provides substantially identical or other desired contrast indices for all of the masks or negatives in a set. The exposure time required for each mask or negative in the set is then determined so that the color components of the exposures will be balanced in the manner desired when the exposures are developed for the predetermined development time. The exposures may then be made in the apparatus provided for that purpose.The apparatus of the invention includes means for rotating a slide transparency and an opaque shield to expose four quadrants of a single piece of film in sequence.

Abstract: The apparatus comprises a device for forming a latent image on a negative film according to data stored on a base medium; a first pair of transport rollers for pinching and carrying simultaneously the negative film and a receiving strip into a superimposition zone, the exposed film being developed into a treatment bath along said superimposition zone and a positive image being transferred by diffusion onto the receiving strip from the negative film; a second pair of transport rollers placed at the outlet of the superimposition zone, for pinching and carrying the receiving strip only; and registering means for sensing the advancing movement of the receiving strip and for controlling intermittently, at time intervals determined by the detection of guidemarks formed on the receiving strip, the production on the negative film of an image comprising a set of data stored discontinuously on the base medium.

Abstract: Apparatus for registering and imagewise exposing to actinic radiation a sequence of similar sheet substrates employing liquid applicator means to allow a photomask to contact a photosensitive layer on the substrate through a liquid.

Abstract: A document conveying device having the capability of varying its recirculation path length in accordance with measured document size disables its recirculating path whenever a document exceeds a predetermined size.

Abstract: A positioning device is disclosed, designed for use in the color separation plate making industry, whereby several sets of original films may be mounted on base sheets, each member of a set being mounted on a different base sheet in the same position relative to the members of the other sets. The invention employs a rotating frame which has several faces on which base sheets are mounted, and incorporates a positioning device adapted to locate original films accurately at corresponding positions on the different faces. Thus the invention achieves its desired result accurately, conveniently, and cheaply.

Abstract: An apparatus for handling a substantially continuous strip or web of photosensitive material is provided with an overlying photographic endless master copy band caused to move in a path that includes a portion at all times in contact with a photosensitive strip or web. The superposed band and web travel through an exposure on an endless carrier band on which they are tightly pressed together by weighted transparent means through which exposing or printing light rays pass to impress the photosensitive material with images derived from the copy band. Following exposure the exposed material and the copy band separate, the latter moving on in its closed path for further printing and the former moving in a separate path to developing and fixing operations.

Abstract: An apparatus suitable for use in transporting microfiche master frames, preferably containing microfiche, either from a loading station to an operating station and from the operating station selectively back to the loading station for a repeat transport by said apparatus, or to an exit station. The transport apparatus comprises a feed mechanism for feeding a master frame from the loading station to the operating station, and from the operating station to an elevator. The elevator lifts the master frame which is then selectively ejected from the elevator to either a recycle means or an exit means. The exit means delivers the master frames ejected thereto to an exit station from where the master frames may be removed from the transport apparatus, while the recycle means delivers the master frames delivered thereto back to the loading station from where the master frames are recycled through the transport apparatus.
