  • Patent number: 4746956
    Abstract: A microfilm strip includes image frames arranged in chapters with indicia provided identifying those image frames which head the chapters. When it is desired to produce multiple prints of each of the image frames in a chapter the image frame comprising the first frame or head of the chapter is moved into the print gate. Upon entry of the print command signal, the strip is automatically advanced so that the last frame of the chapter is in the print gate. The printer then automatically prints each frame of the chapter starting with the last frame and ending with the first frame of the chapter. The prints arrive face-up at the output of the printer in collated form. As multiple sets of prints of the chapter are desired, the microfilm after printing the first image frame, returns to the last image frame for repeat printing of another set of prints of the chapter. This operation is repeated until the number of sets of collated prints is provided at the output.

  • Patent number: 4455066
    Abstract: A display terminal is provided which holds a roll of film, and can project the image of any film frame onto a console screen. The need for a platen to precisely locate a frame on the optical imaging plane, is avoided by keeping the film in tension. The tension is maintained while the film is stationary, by utilizing a pair of reel-driving motors that each provide a torque that varies with the diameter of the film roll on the corresponding reel. The film region being projected, can be held in a slight curve to more reliably hold all areas of the projected film region near a predetermined film plane. A film identification track and clock track can extend along one edge of the film to identify every frame and accurately center the frame at the imaging, or projection, station. The film can be rapidly moved to bring a desired frame to approximately the imaging station, with slight overshoot, and the film then can be inched back to center the frame.

  • Patent number: 4219737
    Abstract: A system for optically detecting the presence of indicating markers on microfilm frames and for ignoring stray marks and smudges. As light shines through the microfilm and is detected by a photo-transistor, the system self regulates to provide an absolute baseline value, called a prescaler, for each frame of microfilm. Then, as each mark appears on the microfilm and interrupts the light path to the photo-transistor, the degree or extent of light blockage is measured as a deviation from the baseline for that frame. If the deviation exceeds a predetermined threshold, the mark is counted as a marker; otherwise the mark is ignored as a stray spot or smudge. The threshold is also self regulated based on a percentage of the amount that the light blockage of the marker in the immediately preceding frame deviated from the baseline for that frame.

  • Patent number: 4198157
    Abstract: An automatic microfilm camera is positioned to take images of a document while it is being read by an operator of a computer terminal. The computer generates a computer index number, and perhaps other significant information, which is forwarded via an interface circuit to display a readout of alpha-numerical images within the photographic area adjacent to the copied document. The camera automatically takes a picture of the document and the display when the operator pushes an "Enter" or other appropriate button on the computer terminal, thereby photocopying both the document and the displayed images. An important aspect of the invention is that the photographic cycle is initiated automatically by an appropriate step in the data entry sequence, whereby the normal data entry procedures are not disturbed by the existance or the use of the camera. An advantage is that the camera and computer are inherently synchronized and cannot lose their mutual sequencing.

Microfilm projecting means mounted in the filmpath between feed and take-up reels clearly display on a viewing screen a page of information when the microfilm is stationary in accordance with existing technology. The high speed search system is new technology. A strobe lamp displays indexes of the moving microfilm on a screen. Each of the frames having an index of digital form and also has an optically detectable marker.

  • Patent number: 4016406
    Abstract: A first counter stores the number of a desired microfilm frame to be located at an access position. A second counter stores the number of the present frame at the access position. The microfilm is normally driven at a high speed, but it is desired to drive the microfilm at a lower speed for a predetermined number of frames prior to the arrival of the desired frame at the access position. This predetermined number is set into a compensating circuit. A comparator first determines the magnitude and sense of the difference between the two counters while the film is stationary. The predetermined number is then added to the contents of the second counter, and the film is driven until the comparator detects a first equality of the contents of the first and second counter, thereby switching the film drive to the lower speed.

  • Patent number: 3963336
    Abstract: Apparatus and a method for handling and reading any one of a number of film strips, each having a number of segments with each segment containing a plurality of information-containing, high-reduction image frames. The film strips are housed in a cassette which is movable with respect to a fixed reference to align a desired film strip with a reading station disposed across the optical path of an optical system. A film strip is moved out of the cassette by a force applied to one of its side edges. Control information carried by each film strip is sensed as the film strip moves out of the cassette and the sensed information is used to control the distance through which the film strip moves so that a particular segment thereof will stop at the reading station. The optical system is moved relative to the reading system so that the optical path of the optical system is selectively alignable with a particular image frame of the film strip removed from the cassette.

  • Patent number: 3937927
    Abstract: Frame location system for microfilm retrieval system. Frame address of desired frame is stored in first reversible counter having maximum count greater than the maximum possible number of frames in a roll of microfilm. Frame address of frame currently being viewed is stored in second reversible counter of same count capacity. A burst of pulses equal to capacity of both counters causes both to count up. First counter to overflow gates burst pulses into third reversible counter. Second counter to overflow terminates count in third counter. As microfilm moves, optical sensors sense frame identifying "blips" on microfilm thereby reducing count in third counter and slowing film to halt when desired frame is in position at viewing station.
