摘要： The present invention is used in photo-recording machines, such as microfiche recorders, which receive a document and record an image of the document on a photo-recording medium such as photoplastic film. The invention inhibits double exposures on frames of the film by use of distinctive indicator marks recorded on the film at preselected locations called indicator mark fields. The presence or absence of an indicator mark in such an indicator mark field signifies, respectively, that its corresponding frame is or is not available for recording a document image.In an improved recorder, prior to a proposed recording, a detector scans the indicator mark field corresponding to the frame selected for recording. If the detector detects an indicator mark, the recorder is inihibited from recording the document in the selected frame. A projection light source forms the image of the indicator mark field and projects it along an optical path in which a sensor of the detector is interposed. Where the indicator mark includes lighter and darker portions, the sensor responds to the intensity variations and may be mounted on motive means and swept thereby across the optical path transversely. The sensor output is automatically evaluated by means which may include or cooperate with a logic circuit responding to an evaluation signal and preventing recording despite a operator-entered record instruction.If no indicator mark is dectected, document recording proceeds in the selected frame, and an indicator mark is simultaneously recorded in the corresponding indicator mark field.

摘要： A method and system for automatically calibrating a D.C. transducer are described in the environment of an illustrative film retrieval system. In this system, the output of a transducer such as a light sensor is amplified and the amplified output is compared to upper and lower limits within which it is desired to hold the transducer's amplified output. When either of the limits is exceeded, the amplification of the transducer's output is varied so as to shift its average value to a value which is between the upper and lower limits.

摘要： The disclosure relates to an electronic document detector particularly adapted for but not limited to use in a document recording system. The document detector comprises a light source, a current source which includes a light sensitive element spaced from the light source and arranged for receiving at least a portion of the light output of the light source for providing a current having a magnitude directly related to the amount of light received by the element, wherein the space between the light source and the light sensitive element defines a path in which documents to be detected traverse. As each document traverses the path, the light sensitive element is shielded from the light source. A current sink coupled to the current source has an input and an output for providing at its output an intermediate control voltage having a magnitude related to the magnitude of the current provided by the current source and within a first range below a given level and within a second range above the given level. A voltage detector coupled to the output of the current sink provides a document indicative signal when the intermediate control voltage falls below the given level into the first range. An intermediate control voltage restoring means coupled between the current sink output and the current sink input restores the intermediate control voltage to a predetermined level within the second range after each document traverses the path.

摘要： A film transport mechanism moves film from area to area and then stops it to project an image. During the period while the film is being transported, the lens is shuttered and glass flats on either side of the film are opened. This way, the viewer does not see a blurred montage of images being moved across a screen at a high rate of speed, and there is a much less chance of scratching film. The shutter may be either a mechanical blade which cuts across a beam of light or an electrical circuit which dims a light supply to darken the screen. Dimming is preferred to switching a lamp off or on since it is much less damaging to a filament if it remains continuously energized.

摘要： An electronically controlled photographic image utilization device is arranged to transport a roll of microfilm having all images printed thereon in separate photographic areas, each area being arranged in a microfiche-type format. The photographic image utilization device has an automatic call-up feature so that any given photographic area may be selected in a first dimension and projected responsive to the push of a button, the operation of a rotary switch or both. A special bar code is printed along the edge of the film and used in conjunction with a closed loop film control system to eliminate the need for precise, clock-controlled synchronization between the film transport and the code reading. Preferably, the bar code is read by optical electronic sensors. Responsive thereto, the electronic control system accurately positions a selected photographic image, on the microfilm, within a viewing area. Thereafter, and while the film transport is being held stationary, any image on the microfilm may be selected for projection by a manual movement in second and third dimensions of a simple lens positioning mechanism which is small, compact, and easily moved. The reader may also be operated manually so that the automatic controls may be bypassed, if desired.

摘要： The disclosure relates to a system and method for expanding the capacity of the logic control for an information bearing element retrieval system. The system disclosed includes means for determining if the absolute numerical difference between a predetermined digit of a current number identifying the current information bearing element being inspected, and a target number identifying the information bearing element to be inspected, is equal to or greater than a preselected integer. If the absolute numerical difference is equal to or greater than the preselected integer, the normal direction of scanning the information bearing elements is reversed. In so doing, a logic control and display having a finite n digit capacity may properly handle consecutively numbered information bearing elements having identification numbers of more than n digits.

摘要： A system is described for holding the tension of a web substantially constant as the web is transported from a supply spool to a take-up spool. The rotation of each spool is controlled by a motor. A tension control circuit senses the currents in both motors and alters motor current so as to hold the sum of the motor currents at a substantially constant value. In this manner, the sum of the torques generated by the motors and their spools is held at a substantially constant value to thereby maintain web tension substantially constant as the radii of the spools change during web movement.

摘要： An automatic microfilm camera is electronically controlled, as by an electronic logic controller, logic and control unit, or the like, for example. The camera has an automatic feeding stack loader for picking up documents of randomly mixed sizes, photographing them, and then depositing them in an output tray. The automatic feed may be interrupted, so that single documents may be copied. Then, the automatic feed restarts and continues from the point of interrupt. A plurality of sensors respond to documents in order to control both the time of shutter opening and the exposure actuation. Various forms of documents may be processed, including a fan-folded computer readout requiring a pin drive wheel.
