  • Patent number: 4819034
    Abstract: A method and a microfilm camera for detecting codes applied to original copies being screened in the camera in which a code reader detects the codes, and a counter and comparison device is provided, which is connected to the code reader and is adjusted to a predetermined number of the copies. Two intermediate memories are connected to the counter and comparison device. The memories count and store marks for the blip types and codes from the code reader, respectively. The code value, the blip mark value and the copy number value are compared in the counter and comparison device and when coincide, a copy supply which was previously stopped is switched on again.

  • Patent number: 4757352
    Abstract: To monitor the picture taking of documents in a camera assembly including a paging device and an exposure device, the documents pertaining to a partial stack of documents are provided with serial page numbers within a digital range assigned to the partial stack. In the exposure device the film pictures are exposed with a blip sign whose shape is assigned to the processed digital range. During the passage of respective documents through the assembly, an electronic control generates in the respective paging and exposure devices binary coded first and second signals assigned to the digital range of the serial numbers and to the corresponding blip signs. The first and second binary coded signals are applied via evaluation units and a comparator into an intermediate memory.

  • Patent number: 4564276
    Abstract: An apparatus for sensing microfilms is provided in addition to visible light with a projection lamp for radiating infrared rays which pass through a cold-light mirror to a platform on which a microfilm is disposed. The apparatus is further provided with a projection lens positioned above the microfilm platform. The path of rays is directed from the microfilm platform through the projection lens and then is projected onto an image screen or other sensing surface, for example CCD-device. For adjusting the apparatus for various light spectrum combinations the apparatus is provided with at least one infrared component-reflecting mirror which is displaceable or pivotable to and from the path of illumination rays radiated from the projection lamp.

  • Patent number: 4349730
    Abstract: The data processing device for reading and processing visually observable information taking place on a data carrier includes a hand operated reading unit guidable in a first direction along a line of the text on the data carrier; scanning unit in the form of a column of photoelectric elements is arranged in the reading unit in a direction perpendicular to the direction of movement of the reading unit; and timing means provided in the reading unit for controlling the scanning rate of respective elements in response to the speed of movement of the reading unit.
