    摘要: Image information is recorded in plural frames of a microfilm. A key device having keys representing letters or numerals inputs a keyword repesenting the information to be retrieved. A memory stores information representing the correspondence-relationship between the keyword representing image information and the frame number of the frame in which the image information is recorded. A comparator circuit compares the keyword with the information in the memory so as to output the frame number of the desired frame. The output signal of frame number drives a shifting device so as to project the desired frame on a screen. In addition, an optical disk memory is used as the memory by reason of its adaptability for a microfilm projecting system.

    摘要: A color image displaying picture tube having no fluorescent dots or stripes on the face plate. The electron beam in the tube is light modulated with a light wave and demodulated on the face plate to emit a light corresponding to the modulating light wave. The electron beam modulated with a red light emits a red light on the face plate.
