ABSTRACT:
A document filing apparatus is provided with a main unit for outputting parallel bit data, and a display device coupled to the main unit through an interface cable having a plurality of bit transmission lines. The display device comprises a multiplier circuit for multiplying the frequency of a clock pulse at a predetermined frequency, a parallel-in/serial-out shift register for receiving an image signal obtained by finely scanning a document, via the interface cable, as parallel image data, and for converting the parallel image data into serial image data in synchronism with a multiplied clock pulse signal from the multiplifer circuit, and cathode-ray tube for displaying image data obtained from the shift register as an image.
