  • Patent number: 6061148
    Abstract: A facsimile apparatus prints out a received image interrupted during the reception by the same process for both the interruption of a communication line and the power failure of a power supply. A bit pattern called a page interruption code which does not appear in normal code data is used as data to be overwritten to erase the past image data stored in a buffer memory. In a decoding process, a function to detect an RTC code which is a normal page end code and a function to detect the page interruption code are provided so that the image interrupted during the reception is printed out to at least the last point of the received image.

  • Patent number: 5930192
    Abstract: A change over unit 12 is controlled to become conductive only when useful data is stored in a memory 15 for storing data to be processed. Therefore, when a main power supply is shut off, a memory backup function of a backup battery 13 is operated only when useful data is stored in the memory 15, thereby preventing unnecessary backup, which results in preventing the backup battery 13 from unnecessarily discharging and realizing a reliable memory backup.

  • Patent number: 5489990
    Abstract: An image forming apparatus forms interpolating image data of a plurality of lines subjected to smoothing processing including original image data from the original image data. The apparatus selects and outputs image data of a predetermined number of lines corresponding to a reduction ratio from among the image data of the plurality of lines. A reduced image subjected to smoothing processing with high picture quality without loss of information of original lines is thereby obtained.

  • Patent number: 5291303
    Abstract: A facsimile apparatus has a first coder for coding image data by a one-dimensional coding method or a two-dimensional coding method, and a second coder for performing coding by a second coding method different from these coding methods. When the amount of code of one line coded by the first coder exceeds a predetermined amount, coding by the first coder is suspended and the image data are coded upon making a changeover to coding by the second coder. In addition, a code resulting from coding by the one- or two-dimensional coding method and a code resulting from coding by the second coding method can be received and decoded.

  • Patent number: 5280361
    Abstract: A data processing apparatus comprises: code analyzing means for analyzing input code data encoded by a two-dimension encoding system; developing means for developing the code data in accordance with an analysis result by the code analyzing means, to produce decoded data; and means for stopping the analysis by the code analyzing means by detecting a horizontal mode code by the code analyzing means, and resuming the analysis by the code analyzing means by the completion of the development of the analyzed code data by the developing means. The code analyzing means and the developing means are parallelly operated, and upon detection of the horizontal mode code, the analysis by the code analyzing means is temporarily stopped until the development of the analyzed code data is over.

  • Patent number: 5276526
    Abstract: A decoding device for two-dimensional codes employs a first serial reference line signal which assumes the value "1" only at the change point from black to white, and a second reference line signal which assumes the value "1" only at the change point from white to black, either of which is selected according to the color of the start pixel. The end of a reference line can be identified by the value "1" in both reference line signals. The decoding device can thus achieve high-speed development of two-dimensional codes without a large-scale logic circuit.
