  • Patent number: 6779441
    Abstract: Disclosed is an automatic metal printer which prints a camera-photographed and computer-processed image on a surface of a hard material, such as a metal sheet, through a dot matrix printing type method wherein brightness of the printed image is expressed in accordance with density of dots in the dot matrix formed on the surface of the hard material. The automatic metal printer includes a platform which reciprocates forward and rearward in a lower portion of a body by a motor-operated first ball screw. A saddle is installed at a position above the platform so as to reciprocate to the left and right in the body by a motor-operated second ball screw. A dotter is vertically installed on the saddle so as to dot the upper surface of the hard material seated on the platform to print a desired image.

  • Patent number: 6772907
    Abstract: An automatic tablet dispensing and packaging system comprises a tablet dropping unit and a tablet packaging unit. The tablet dropping unit has door cabinets serving as a front double door of the system and slider cabinets horizontally aligned in rear of the door cabinets. The slider cabinets are linearly slidable to move back and forth so that the forward sliding (toward the door cabinet) of the slider cabinets can be effected when the door cabinets are swung open. Tablet cassettes having tablets are detachably racked in each cabinet in columns and rows. Hoppers to guide down the tablets into the tablet packaging unit are provided such that angles formed by a vertical line and respective inner side surfaces of the hoppers are gradually decremented to efficiently decrease tablet impact on the inner side surfaces of the hoppers.
