There is provided a document reader system for reading images of a large number of document papers while continuously feeding the document papers from an auto-feeder to a scanner so that image data read by the scanner can be supplied to a computer, which can easily meet various requirements of different users, easily satisfy a user having only a scanner and planning to purchase a microfilm camera additionally, reduce space needed for installing the whole system without providing double auto-feeders and stackers for the scanner and the microfilm camera, and which allows makers to easily provide various types of systems to meet user's requirements. The system includes a turn unit removably attached to the scanner so that the document papers passing through and ejected from the scanner can be returned to a stacker provided in the scanner. Each device portion of the system is formed as a unit so that various types of document reader systems can be obtained by combining necessary units.

An automatic film processor for passing an exposed film successively through developing, fixing and rinsing stations to effect continuous development thereof. The film is applied with ultrasonic vibrations as it moves through the treating liquids to accelerate the treating speed, the ultrasonic vibrations being applied to the film such that the surface of the film is not perpendicular to the direction along which the ultrasonic wave has its maximum directivity. Arrangements for further promoting the effect by the application of ultrasonic vibrations are also provided. By the combined use of the application of ultrasonic vibration and preheating of the film, processing speed is further increased. Preheating of the film is controlled depending on the integrated amount of the already processed film, the density of the developed image or the feed rate or moving speed of the film.
摘要:
A process for developing a film having one or more photographed image areas, so that the photographed image areas are developed under an optimum condition to have appropriate densities. In the first step, a region of the film, other than the photographed image areas, is exposed with a constant quantity of light. The region exposed to the constant quantity of light is then developed prior to the development of the photographed image areas. The density of the image in the region exposed to the constant quantity of light is detected and compared with a characteristic curve showing the change in density of the developed image in terms of the quantity of exposure light to find the optimum condition for development. The photographed image areas are then developed under the thus found optimum condition. The condition for development may be controlled by varying the film feed rate, the concentration of the developing reagent in the developing liquid, the quantity of the developing liquid supplied to contact with the film or by changing the temperature of the developing liquid. An additional region exposed to the constant quantity of light may be provided and used for setting the optimum condition for printing.

An improvement of microfilm camera with a marking device in which an image of a document is photographed on a roll film mounted in a cassette using a slit exposure system and a two-dimensional digital image of a mark is recorded on the roll film. The microfilm camera comprises: an image taking lens for forming the image of the document on the roll film; a mark taking lens having an optical axis inclined in the length side direction of the roll film with respect to that of the image taking lens; and a digital image generator for generating a one-dimensional digital image extending in the width side direction of the roll film and formed by said mark taking lens at or in close vicinity of the image forming position of the image taking lens. The two-dimensional image of the mark is recorded on the film by changing the one-dimensional digital image synchronously with traveling of the film. With such construction, the size of a photographic opening provided in the cassette can be reduced to made the cassette structure simple. It is unnecessary to provide a complicated synchronizing mechanism for setting mark projecting or recording timing.

There is provided a microfilm cassette capable of reducing the case size and obtaining a rational arrangement of elements such as reels and photographic roller. The microfilm cassette includes: a case having a substantially rectangular shape as viewed from the top; a supply reel and a take-up reel mounted inside the case and arranged adjacent to each other horizontally in the length side direction of the case; a photographic opening located around the center of one short side of the case; a photographic roller arranged in a position opposite to the photographic opening; and a shutter for opening and closing the photographic opening. The short side of the cassette case on which the photographic opening is located may be bulged and expanded outwardly around the center of the photographic opening, so that the mark taking lens and the image taking lens can be arranged close to each other. Further, a pair of labels may be attached to the case in positions substantially symmetric with respect to the central axis parallel to the long side of the case. The microfilm camera for this microfilm cassette is also provided.
摘要:
A rotary camera for photographing a plurality of original documents on microfilm and for recording information relating to the photographed original documents together with data concerning the conditions for photographing additional necessary data. The rotary camera has an exposure roller on which images of the original documents are focused to be photographed and unidimensionally arranged light emitting elements opposed to the exposure roller. The light emitting elements are selectively energized so that the microfilm is exposed to the data-writing lights forming any desired images of the data in the form of letters, numerals or marks while moving in contact with the exposure roller. The data to be recorded is designated and is put into the control system through a keyboard. A jam-mark may be recorded on the microfilm as the data in response to an output from a jamming detector. Similarly, a lamp failure mark may be recorded when a lamp failure condition is detected by a sensor sensing insufficient illuminating of the original document being photographed.

An improved cut sheet feeder for feeding cut sheets separately one by one, comprising a sheet feeding and conveying device for contacting the obverse side of a first sheet to move the first sheet forwardly by frictional force, an arresting device for contacting the reverse side of a next sheet to arrest forward movement of the next sheet, the frictional force applied by the sheet feeding and conveying device being larger than the frictional force applied by the arresting device. The improved cut sheet feeder comprises a suction device operatively associated with the sheet feeding and conveying device for sucking the first sheet to increase the frictional force between the first sheet and the sheet feeding and conveying device. In a modified embodiment, a suction device may be operatively associated with the arresting device rather than being operatively associated with the sheet feeding and conveying device. In a further modified embodiment, a suction device may be operatively associated with the arresting device in addition to the suction device operatively associated with the sheet feeding and conveying device.

A document processor comprises an image reader for reading a document sheet to output digital RGB signals, a color model converter that converts the RGB signals to HSV signals and YUV signals through arithmetic operations, and then attaches the YUV signals to the HSV signals of individual pixels, a color detector for detecting pixels of those colors to be subjected to image processing; and an image processing section consisting of a color converter, a color extractor and an area recognizer. The image processing section is previously registered with a number of colors to be subjected to image processing, wherein different contents of image processing are designated to respective colors, so the color converter, the color extractor and the area recognizer can carry out designated contents of image processing simultaneously on pixels of registered colors.
