Patent number: 7404683Abstract: In a printer, when a cover is closed, a paper issuing path, and a paper setting path are formed downstream from a cutter mechanism in a paper transport path. The paths are switched over by a movable guide. During a normal printing process, the movable guide is swung by its own weight to close the paper setting path, and guides a paper to the paper issuing path. By contrast, during a process of setting paper, the movable guide is swung by the rigidity of the paper itself toward the paper issuing path, whereby the paper is prevented from being deformed with respect to the cutter mechanism.Type: GrantFiled: April 18, 2005Date of Patent: July 29, 2008Assignee: Star Micronics Co., Ltd.Inventors: Yasufumi Mochizuki, Osamu Mizuno, Tadashi Nonaka

Patent number: 7401554Abstract: To modify an existing printing press from its original length/cut off to a different cut off, a sub-frame may be mounted on an existing frame of a printing press. The sub-frame permits the relocation of bearing supports for various printing cylinders, such as, for example, the plate cylinders and blanket cylinders. In addition to mounting the sub-frame on the existing frame, new plate and blanket cylinders having different sizes than the plate and blanket cylinders used in the existing printing press may be mounted in the sub-frame to provide different printing lengths/cut offs. Suitable sleeves, such as the eccentric mounting sleeves may be provided as necessary in order to mount the cylinders to the sub-frame.Type: GrantFiled: April 24, 2006Date of Patent: July 22, 2008Assignee: Goss International CorporationInventors: Dan Zimich, Dan Machaj

Patent number: 7384205Abstract: The present invention operates in a printing apparatus capable of carrying out printing by switching between a mode using a set of toners for four colors Y, M, C, and K and a mode using a set of toners for six colors including the four primary colors, light cyan, and light magenta. Specifically, when a page layout included in “Page Layout” set items is set for N (N>1) sheet/page, printing is determined to be carried out in the 4 color mode to set a print specification in a job ticket for the 4 color mode. If a plurality of page units are printed within one page, each page unit is contracted when printed. Accordingly, it is often difficult to perceive printed image quality when observing the image. Thus, even if the 6 color mode is set, printing is controlled to be carried out in the 4 color mode.Type: GrantFiled: December 1, 2004Date of Patent: June 10, 2008Assignee: Canon Kabushiki KaishaInventor: Joji Oki
