  • Patent number: 4745489
    Abstract: An image recording apparatus includes a lamp, a CCD array, an image density adjustor, first and second shutter drivers, first and second shutters, an image area discriminating circuit, and a microcomputer. The lamp illuminates an image and retrieval information of a microfilm having the image and the retrieval information at the side of the image. The CCD array receives light from the image and the retrieval information on the microfilm illuminated by the lamp. The image density adjustor, first and second shutter drivers, and first and second shutters cooperate with each other to record the image of the microfilm on a recording medium. The image area discriminating circuit discriminates the image from the retrieval information according to an output from the CCD array. The microcomputer controls the image density adjustor and the first and second shutter drivers so as not to record the retrieval information on the recording medium according to an output from the image area discriminating circuit.
