  • Cable extension unit
    Patent number: 7274405
    Abstract: Synchronous signal overlapping and outputting means and sound signal transmitting means of a signal transmitter transmit any color signal which synchronous signals overlapped and the other color signals, and a sound signal on which polarity information of the synchronous signals was added through four signal lines to a signal receiver, respectively. Synchronous signal recovering and outputting means of the signal receiver recovers the synchronous signals on the basis of the synchronous signals separated from the color signal with the polarity information and outputs the signals to an image output unit. Then, it is possible to output sounds together with images inputted from the image inputting source from the image outputting unit with only four signal lines.

  • Waste collecting device of an ink jet printer
    Patent number: 4901094
    Abstract: An ink jet printer is equipped with a cap for covering a nozzle face to prevent the nozzle from clogging and has maintenance solution supplied to the cap. A waste collecting device is provided in the printer and includes a powder type absorbent placed in a waste collecting tank case so that waste liquid such as maintenance solution and ink led from the cap into the tank case is absorbed by and retained in the powder absorbent.
