  • Patent number: 6283649
    Abstract: A plurality of thermal heads for different colors, are disposed in parallel in a line-printing direction, being offset with respect to each other in a transport direction along which an image-forming sheet is moved via a conveyer path. The image forming sheet is a pressure/temperature-sensitive sheet or a temperature-sensitive sheet. The thermal heads are moved in the line-printing direction. Adjacent-opposing ends of adjacent thermal heads are separated in the line-printing direction, and overlap in the transport direction. The thermal heads are controlled so as to simultaneously generate image-pixels on the image-forming sheet. The printing speed is high due to a plurality of colors being simultaneously printed. The thermal heads are used as part of pressure applying unit. The pressure applying unit is provided for selectively applying predetermined pressure to the micro-capsules, when the image-forming sheet is a pressure/temperature-sensitive sheet.

  • Patent number: 6280107
    Abstract: A peeling device according to one aspect of the invention peels off part of a peel-off paper from a peel-off paper-backed adhesive tape which is a laminate of a substrate tape having a surface coated with an adhesive and a peel-off paper affixed to the substrate tape via the adhesive. A rotational member is rotated by a driving force transmitted from a drive source. On an end face of the rotational member there are arranged a peeling projection rotated to be brought into contact with a substrate tape-side surface of an end of the peel-off paper-backed adhesive tape to carry out a bending releasing action on said end portion of the adhesive tape. The adhesive tape is guided toward the peeling projection when it is inserted and part of the end portion other than a free end brought to the peeling projection is held.
