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. After developing, the image may be automatically retrieved by the computer and displayed by a suitable microfilm projector.
