Patent number: 10800182Abstract: The theoretical position of a registration mark is automatically obtained by image processing on predetermined image data. A printing system including a printing apparatus capable of further performing coating printing on a substrate having undergone printing includes a generator that generates theoretical position data of a registration mark by performing image processing on registration image data assumed to contain a registration mark, an acquirer that acquires reading position data by reading the position of a registration mark printed in advance on conveyed paper, and a printing controller that compares the theoretical position data with the reading position data and corrects a position of coating printing based on the misregistration.Type: GrantFiled: December 21, 2018Date of Patent: October 13, 2020Assignee: DUPLO CORPORATIONInventor: Shuhei Yamamoto

Patent number: 9463652Abstract: On a sheet of paper on which an image has already been formed, a first registration mark pair and a second registration mark pair are printed. The first registration mark pair and second registration mark pair each consist of a pair of registration marks that are arranged to be spaced apart in a paper-width direction, the second registration mark pair located posterior to the first registration mark pair in the paper-conveying direction. Based on the actual positional relationship between the first registration mark pair and the second registration mark pair that are read by a reading unit, a correction unit corrects discharge data that corresponds to an image formation area located between the first registration mark pair and the second registration mark pair.Type: GrantFiled: October 27, 2015Date of Patent: October 11, 2016Assignee: DUPLO CORPORATIONInventor: Shuhei Yamamoto

Patent number: 7740240Abstract: In a paper feeding apparatus, a paper feeding unit has a paper mounting surface provided with an air-blowing outlet. The paper feeding structure feeds an uppermost sheet of a stack of paper on the paper mounting surface. An air pump supplies air to an air-blowing outlet, a first air-blowing member and a second air-blowing member. The air-blowing outlet is so provided as to blow air to an approximately whole undersurface of the paper stacked on the paper mounting surface. When air is being supplied to the air-blowing outlet, an electronic control unit inhibits the feeding of sheets of paper by the paper feeding unit.Type: GrantFiled: June 15, 2007Date of Patent: June 22, 2010Assignee: Duplo CorporationInventor: Shinichi Iwakiri

Patent number: 7354233Abstract: In a bookbinding machine, an image forming apparatus, a prebinding apparatus and a bookbinding apparatus are coupled on line in this order. In the prebinding apparatus, a sheet aligning section, a slitting section which cuts off margins at both side portions of a sheet of paper, a cutting section which cuts off top and bottom margins, and a creasing section are arranged in this order. The prebinding apparatus is provided with a control section which sorts out supplied sheets of paper into those which need an SCC step and those which do not, and performs the SCC step only on the sheets of paper that need the SCC step.Type: GrantFiled: November 10, 2004Date of Patent: April 8, 2008Assignee: Duplo CorporationInventors: Yutaka Oki, Masatoshi Takahashi, Yuichi Misawa

Patent number: 5310171Abstract: The collating device sucks up the topmost sheet of the paper stack on the paper table by the suction head and feeds forward the sheet one after another. The paper table is being given an upward force by a spring. This paper table moves up to the position where the topmost sheet of the paper stack on the paper table contacts with a stopper. This stopper moves up during the period when the suction head feeds forward the topmost sheet. At this time, an electromagnetic brake is set at the on-state and fixes the position of the paper table. The suction head, stopper, electromagnetic brake and the like rotate at the predetermined timing based on the rotation of cams. Thus, according to this invention it is possible not only to save the cost of the device but also to operate the device at high speed.Type: GrantFiled: February 18, 1993Date of Patent: May 10, 1994Assignee: Duplo CorporationInventors: Tomio Honma, Hideo Tanaka

Patent number: 5301935Abstract: The envelope is always moved in a direction perpendicular to the fold of the flap thereof. In the course of the moving path the moving direction of the envelope is turned over by means of reverse roller 15, the flap is folded and the opening of the envelope is expanded while the envelope is being halted at the content-inserting portion. In this state the content such as a letter etc. is inserted from the expanded opening of the envelope. Then after the gummed flap is damped, the flap is folded and sealed. Thus, the movement of the envelope can be simplified and the enclosing and sealing apparatus can be reduced in size.Type: GrantFiled: July 15, 1992Date of Patent: April 12, 1994Assignee: Duplo CorporationInventors: Toshio Miki, Masato Takeda, Yoshiyuki Ishikura

Patent number: 5048416Abstract: In each of the pressure transferring sections of the printing device, a pair of cylinders, a screen positioned to pass over the cylinders and an inking device for supplying ink to the original printing stencil on the screen are arranged. An original printing stencil supplying device and a used printing stencil collecting device are moved as an integral unit to the first pressure transferring section by means of a moving device. Then, the used printing stencil on the screen is collected by the used printing stencil collecting device and a new engraved original printing stencil is supplied from the original printing stencil supplying device and mounted on the screen. Ink for the first color is supplied to the original printing stencil by means of the inking device. Then, the original printing stencil supplying device and used printing stencil collecting device are moved to the second pressure transferring section, and the process is repeated.Type: GrantFiled: July 19, 1990Date of Patent: September 17, 1991Assignee: Duplo CorporationInventor: Yutaka Iijima
