Patent number: 6536345Abstract: Apparatus and a method for printing an image on an edible substrate is described. The apparatus comprises a printer head assemble having a container or containers for liquid food colorant. A support for holding an edible substrate adjacent a print head assembly is provided, which support is adjustable such that the surface thereof upon which an edible substrate is placed may be moved in a direction vertically towards and away from the print head assembly. The support and print head assembly are movable laterally relative to one another. A controller is provided for controlling the print head assembly with printing instructions and for controlling relative movement of the support and print head assembly such that an image to be printed on the edible substrate may be printed. The support comprises upper and lower plates, the upper plate being supported in the lower by a scissors mechanism enabling the height of the upper plate relative to the lower to be adjusted.Type: GrantFiled: April 17, 2000Date of Patent: March 25, 2003Assignee: Cadex LimitedInventor: Robert John Young

Patent number: 6505981Abstract: Setting plain paper in a printer which can print on plain paper and a label paper is facilitated using a printer capable of printing a recording medium including a base sheet and at least one label sheet detachably adhered thereon. The printer includes a print head and platen opposing to each other for printing the recording medium. A first printer housing houses the platen, and a second printer housing movably connected to the first housing houses the print head. The printer also includes an ejection port, defined at the border of the first and second printer housings, from which the recording medium is ejected after printed by the print head and platen, and a separator for curving the base sheet ejected from the ejection port to separate the leading edge of the label sheet from the base sheet.Type: GrantFiled: May 11, 2000Date of Patent: January 14, 2003Assignee: Seiko Epson CorporationInventors: Toru Takami, Toshihiro Tsukada

Patent number: 6485206Abstract: A cassette accommodating portion having an upper open structure is provided on a rear side of a body case in a label tape forming device. A first pressing member and a second pressing member protrude downward from right and left of the inner surface of a cover having a center of rotation at the rear side of the body case. A fin-shaped first detector portion and a fin-shaped second detector portion are formed on right and left of the rear side of a cassette to be installed. When the cassette is installed in the cassette accommodating portion in a proper posture and the cover is closed, the first detector portion and the second detector portion are pressed by the first pressing member and the second pressing member, respectively, and thus the cover is completely closed.Type: GrantFiled: September 13, 2000Date of Patent: November 26, 2002Assignee: Brother Kogyo Kabushiki KaishaInventor: Toshihiro Takahashi

Patent number: 6480216Abstract: A print head pressure mechanism is disclosed that maintains uniform pressure between the thermal print head and platen roller regardless of variations in parts precision, and thus prints with uniform print density. The print head pressure mechanism has first and second support shafts disposed at both sides in the direction of a heat element line L1 of the thermal print head, a frame member for supporting the print head, and having first and second contact parts for contacting the first and second support shafts, and an one or more urging unit for pushing the print head to the platen with the urging means operating on the side of the print head opposite the side to which the heat elements are disposed. When the platen is separated from the print head, the platen axis and heat element line L1 of the print head are not parallel to each other.Type: GrantFiled: December 22, 2000Date of Patent: November 12, 2002Assignee: Seiko Epson CorporationInventor: Mitsuhisa Ando

Patent number: 6450714Abstract: A thermal printer is provided. The thermal printer includes a thermal head module, a platen module, and a gear module. The platen module and the gear module are connected to the thermal head module. When setting a recording sheet to the printer, the operator lifts up a knob provided to the platen module, so that the platen module is rotated counterclockwise around a pin provided to the thermal head module. In this manner, the platen separates from the thermal head, and setting a recording sheet becomes easier.Type: GrantFiled: January 10, 2001Date of Patent: September 17, 2002Assignee: Fujitsu Takamisawa Component LimitedInventors: Yukihiro Mori, Sumio Watanabe, Fumio Sakurai

Patent number: 6431773Abstract: In an apparatus for printing on a continuously moving sheet of work material, a frame is provided and defines a work supporting surface over which a sheet of work material is advanced in a first coordinate direction longitudinally of itself. An elongated support is mounted to the frame and extends transversely across the work supporting surface. A print head is mounted to the elongated support and is movable across the support, as well as between a forward and rearward position. During operation, as the work material is continuously advanced through the apparatus, the print head traverses the support and simultaneously moves between the forward and rearward positions, such that the print head has a component of speed in the first coordinate direction approximately equal to the rate at which the work material is advanced.Type: GrantFiled: March 1, 2000Date of Patent: August 13, 2002Assignee: Gerber Technology, Inc.Inventors: A. Bruce Plumley, Darryl Colburn Stein

Patent number: 6406200Abstract: A printer assembly with lateral and longitudinal self-alignment. The printer assembly has a frame, a door which swings open, a motor-driven platen disposed on the door, a print head movably disposed on the frame so as to engage the platen, and a spring coupled to the print head so as to produce both backward force to urge the print head against the platen when the door is closed and torque to rotate the print head upwardly when the door is opened. The frame is provided with a semi-cylindrical paper well and a generally triangular shape for ease of access to the paper well.Type: GrantFiled: July 30, 1999Date of Patent: June 18, 2002Assignee: Inovise Medical, Inc.Inventor: Steven A.

Patent number: 6398434Abstract: A shaft assembly for a thermal printer system for applying loads in an adjustable manner along the length of a thermal print head of the thermal printer system. The shaft assembly includes a shaft, and a plurality of cam mechanisms rotatably mounted on the shaft and adapted to apply respective loads to the thermal print head at respective locations along the length of the thermal print head. Each cam mechanism is rotationally coupled with an adjacent cam mechanism, and is adapted to be rotated from a non-load-applying position to load-applying position and from the load-applying position to subsequent load applying positions. Each cam mechanism is adapted to apply a respective load to structure associated with the thermal print head when the cam mechanism is in any of its load-applying positions.Type: GrantFiled: October 2, 2000Date of Patent: June 4, 2002Inventor: Richard W. Corrigan, Jr.

Patent number: RE38473Abstract: A printhead assembly for a printer with the printhead mounted in the lid of the printer and the platen mounted in the body of the printer. The printhead is spring loaded, permitting it to float in both the vertical and horizontal directions within the lid assembly. Guideposts are located in the body of the printer with a defined positional relationship to the platen. When the lid is closed, the guideposts position the printhead in its correct position with respect to the platen. Mounting the printhead in the lid and the platen in the printer body permits new paper to be loaded quickly and easily by simply pulling the paper past the platen and closing the lid. The cumbersome paper-threading procedure of conventional inexpensive printers is avoided.Type: GrantFiled: May 3, 2001Date of Patent: March 23, 2004Assignee: Zih Corp.Inventor: Lawrence E. Smolenski
