    摘要： An imaging device includes at least one printhead including an aperture plate defining a plurality of apertures, an ink plate and a controller. The at least one printhead is configured to eject liquid ink through the plurality of apertures of the aperture plate. The ink plate is positioned with reference to the aperture plate to enable an ink layer to form between the ink plate and the aperture plate by ink ejected by the printhead. The controller operatively connected to the printhead and configured to operate the printhead to eject the liquid ink to the ink plate to form the link layer.

    摘要： Printing apparatus preferably for printing numerals in calculating machines is disclosed, such apparatus having a plurality of substantially sector-shaped-type carrying members, each of such members being pivotally mounted and provided with a predetermined number of illustratively impression-type members movable generally radially in the vicinity of the circumference of the sector-shaped portion. A ratchet mechanism is provided on each of the sector-shaped portions for ruling or interrupting movement of each of the type carrying members. A plurality of spring-loaded printing hammers are arranged to strike the type members to print selected characters, each of the hammers being provided with corresponding linkage for controlling its movement. The entire apparatus is preferably mounted on a laterally movable carriage, and electronic coding and sensing may be provided for controlling the apparatus for example, in the event of computerized operation.
