摘要:
In der Vorrichtung zum getrennten Führen von zwei Schichtträgerblättern durch ein Bad eines Diffusionsentwicklungsgerätes ist ein Einzugswalzenpaar (2), deren Walzen in der Mitte der Führungsebene je einen Ausstich (2a) aufweisen, und ein mit einer Zunge (5) zwischen den Walzen durch den Ausstich nach außen ragendes Leitelement vorgesehen, das etwa die Form einer gleichschenkligen Dreiecksplatte (8) besitzt. Dabei gehen die Dreiecksspitze in die Zunge über und entlang der Grundlinie des Dreiecks sind beiderseits Abstandsleisten (9) vorgesehen. Auf beiden Seiten der Dreiecksplatte (8) ist im Übergangsbereich von Dreiecksspitze zur Zunge (5) eine aus der Führungsebene ragende Verdickung (11) ausgebildet, die etwa die Form eines Kugelsegmentes hat. Außerdem erstreckt sich die Verdickung (11) bogenartig quer über die Breite der Zunge (5).
摘要:
A photosensitive element (19) has on its photosensitive surface side a non-photosensitive portion having a width D1 extending from the front end to ward the rear end in the transfer direction, and a non-photosensitive portion having a width D2 extending from the rear end to ward the front end in the transfer direction. The region where light is shone to the photosensitive element by an optical head is located between a point a distance D1 away on the upstream side in the transfer direction and a point a distance D2 away on the downstream side in the transfer direction from the center of the transfer roller (5).
摘要:
A novel laminar sheet structure having at least two sheets (12,14) of different stiffnesses in releasably adhering engagement with each other, the sheet of the lesser stiffness having a marginal portion (18) extending beyond an adjacent margin of the sheet with the greater stiffness. Also disclosed is an apparatus for delaminating the laminar sheet structure having at least one rotatably mounted roller (40) with an axial slot (52) in its peripheral surface for receiving the marginal portion of the sheet of lesser stiffness so that the sheet may be wound upon the roller while the sheet of greater stiffness is separated therefrom, and a method of delaminating the structure by the apparatus.
摘要:
A disposable kit of the type adapted for use in film processing apparatus in the processing of a roll of exposed instant type transparency film, preferably of the 35mm format. The kit includes a two-section housing which encloses a roll of sheet material (32), a container (28) of processing liquid and a nozzle dispenser (30) to apply a coating of the liquid to one side of the sheet material as it is is being drawn from the housing prior to being laminated to a length of exposed film. After the appropriate length of sheet material (32) is withdrawn from the kit and the processing cycle is completed, the strip of sheet material is retracted into the kit. A fluted idler roller (36) is mounted in the housing to minimise the sideways migration of any processing liquid remaining on the sheet material (32) when it is retracted into the kit.
摘要:
Apparatus for processing sheet material according to the DTR process, with two liquid applicator rollers (17,18) that are arranged for wetting one side only of each sheet, and with a liquid transfer roller (16) that is arranged for rotation in a tray (14) with processing liquid (15), said rollers being mounted in such a way that there are maintained beads (20,21,22) of processing liquid between either pair of these three rollers, in operation of the apparatus.
摘要:
A method for transferring an image from an image sheet to an image-receiving sheet while the sheets are superposed, and an apparatus therefor. A support plate of good thermal conductivity and rigidity is placed against the sheets, and a cover sheet superposed remotely from the support plate. The resulting assembly is passed through a pair of heated rollers. Cooling rollers may cool the superposed sheets following the image transfer. Additional cooling may be provided.

Ein bildmäßig belichtetes Negativblatt (1) und ein Positivblatt (2) eines Zweiblattdiffusionsmaterials werden, durch einen Klebestreifen (3) querzur Laufrichtung derBlätter (1, 2) miteinander verbunden, zur Benetzung hintereinander durch eine Entwicklungsflüssigkeit (6) geleitet und danach die Steifigkeit der Blätter (1, 2) und die Flexibilität des Klebestreifens (3) zusammen mit einer Auffangvorrichtung (11) und einem darin verstellbaren Anschlag (12) für das erstbenetzte Blatt (2) dazu benutzt, ein selbstständiges V-förmiges Zueinanderfalten der Blätter (1, 2) um die Klebebandknickstelle (14) zu bewirken; eine Umlenkeinrichtung (9) wird so eingestellt, daß die V-förmige gefaltete Knickstelle (14) in den Spalt eines Quetschwalzenpaares (10) geleitet, erfaßt und die Blätter (1,2) zusammengequetscht durch einen Ausführkanal (13) in eine Auffangschale (15) ausgeworfen werden.
摘要:
A pulse signal is detected from an encoder signal of a rotary encoder. The detected pulse signal is used as a signal for controlling a light exposure timing of a line type light exposure head (25) and is used for detecting a transport speed of an instant film. The light exposure head (25) sequentially performs light exposure for a line image on the transported instant film in synchronization with each pulse signal detected from the encoder signal, and a density correction unit (47a) corrects an amount of light emission of the light exposure head (25) depending on the transport speed of the instant film.
摘要:
There is presented a camera (10) comprising a housing (12), and a generally cylindrically-shaped can (30) rotatably mounted in the housing. The can is provided with an elongated opening (32) extending lengthwise of the can, an external surface (42) for supporting a negative film strip (46), and an internal surface (44) for retaining a rolled film processing pad strip (52). An end (48) of the negative film strip and an end (54) of the processing pad strip are fixed to a foil (50) having adhesive thereon for holding the foil on the can external surface and for covering the elongated opening to seal the can. The foil is peelable from the can and from the opening by pulling of the negative film strip from the external can surface. Movement of the foil away from the camera is operative to draw the processing pad strip from within the can while simultaneously drawing exposed negative strip from the camera, with the pad strip overlying the negative strip.
