Patent number: 4558374Abstract: A picture data processing device in which a region specifying original having markings which physically define a region of interest of an original document to be processed is read and stored. When the original document is read, the stored markings are reproduced to mask out the areas of the original document other than the region of interest. A signal processing operation, such as extraction, rearrangement, or size alteration with respect to the selected region can then be performed.Type: GrantFiled: May 11, 1983Date of Patent: December 10, 1985Assignee: Fuji Xerox Co., Ltd.Inventors: Masami Kurata, Takashi Ohmori

Patent number: 4546381Abstract: A multi-function copying machine having a reading section for reading picture data on an original by raster scanning. A recording section has a plurality of recording devices adapted to perform recording at different recording positions. The recording section applies to the recording devices a picture signal for each color for multi-color recording or a picture signal for each side of the original for two-side recording. Recording control is achieved by a control system for controlling the timing of delivery of the picture signal applied to the recording devices. An editing control circuit sets the timing of delivery of a part of the picture signal provided by the reading section to the recording section, for editing the picture data on the original. A memory delays the timing of delivery of a predetermined picture signal to the recording section according to the timing of delivery set by the control system.Type: GrantFiled: March 4, 1983Date of Patent: October 8, 1985Assignee: Fuji Xerox Co., Ltd.Inventors: Masami Kurata, Takashi Ohmori

Patent number: 4532551Abstract: An information reader has a number of linear image sensors dividing one line of picture information into as many parts for reading an original. As these sensors may be relatively shifted in the subscanning direction, signal delay devices are provided corresponding to the sensors for delaying a read out signal by an amount corresponding to the respective shift of the image sensors. The invention removes severe constraints on the placement and alignment of the sensors, facilitating installation and maintenance.Type: GrantFiled: January 4, 1983Date of Patent: July 30, 1985Assignee: Fuji Xerox Co., Ltd.Inventors: Masami Kurata, Takashi Ohmori

Patent number: 4510506Abstract: A recording apparatus in which recording is made several times each line in a partitioning manner part after part on each recording line for which there exists picture data to be printed. The system determines whether there exists picture data to be printed on each line or not. A sub-scanning speed per line is set such that when the determination is made that one or more successive lines immediately before a recording line for which there exists picture data to be printed is or are an entire blank line or successive entire blank lines for which there exists no picture data to be printed, the sub-scanning speed for the entire blank line or successive ones of the successive entire blank lines adjacent to the recording line is selected to be substantially equal to that at the recording line. The sub-scanning speed of other entire blank line or lines for which there exists no picture data is selected to be a speed which is sufficiently higher than that for the recording line.Type: GrantFiled: November 8, 1982Date of Patent: April 9, 1985Assignee: Fuji Xerox Co., Ltd.Inventors: Haruhiko Moriguchi, Fujio Moriguchi, Takashi Ohmori

Patent number: 4502065Abstract: A transfer type heat-sensitive recording medium having a porous base impregnated with a colorless color former. A layer of thermally melting ink is formed on one side of the porous base. The first layer is brought into contact with a recording sheet. A layer of thermally melting wax containing a color developer is formed on the opposite side of said porous base and selectively heated according to a video signal. The wax melts and permeates into the porous base to allow the color developer to color on reaction with the colorless color former. The wax layer is further heated by thermal irradiating so that the ink of the ink layer is molten in correspondence to the coloring.Type: GrantFiled: February 10, 1983Date of Patent: February 26, 1985Assignee: Fuji Xerox Co., Ltd.Inventors: Haruhiko Moriguchi, Yoshiki Kikuchi, Takashi Ohmori

Patent number: 4481518Abstract: A heat-sensitive transfer type recording device is provided with a thermal head having heat generating elements and a backing roll operatively positioned relative to the heat generating elements to accommodate the passage of an ink donor sheet and a recording sheet therebetween under pressure. A separation roll is spaced from the backing roll to provide for the passage of said ink donor sheet and said recording sheet therebetween at a pressure substantially less than the pressure exerted on the sheets upon passage between the backing roll and the heat generating elements. The ink donor sheet is directed about the separation roll at a relatively sharp angle to separate the recording sheet from the ink donor sheet with a complete transfer of the ink from the ink donor sheet to the recording sheet as a result of the reduced pressure on the sheets at the separation roll.Type: GrantFiled: September 27, 1982Date of Patent: November 6, 1984Assignee: Fuji Xerox Co., Ltd.Inventors: Toshiharu Inui, Fujio Moriguchi, Takashi Ohmori

Patent number: 4476179Abstract: An ink donor sheet comprising a porous sheet and a heat-fusible ink layer formed on it is disclosed. The ink layer has such temperature-dependent gradation characteristics that it remains solid at ordinary temperatures and when it is heated to a certain temperature its viscosity is suddenly decreased and upon further heating, the viscosity is decreased gradually. The ink donor sheet is capable of producing halftones in the images it creates.Type: GrantFiled: August 30, 1982Date of Patent: October 9, 1984Assignee: Fuji Xerox Co., Ltd.Inventors: Haruhiko Moriguchi, Toshiharu Inui, Takashi Ohmori

Patent number: 4469433Abstract: A color copying machine includes a device separating the image information from each area of the original into colors corresponding to predetermined recording colors to thereby form corresponding video signals. A preferential selection circuit converts each video signal into a 2-level signal and performs an arithmetic operation on each 2-level signal to thereby key the image information from each area of the original to one of the recording colors or white. Black is selected as the recording color if a chromatic color competes with black in the same area.Type: GrantFiled: October 28, 1982Date of Patent: September 4, 1984Assignee: Fuji Xerox Co., Ltd.Inventors: Masami Kurata, Takashi Ohmori

Patent number: 4463301Abstract: A step motor driving circuit having A-phase and B-phase exciting windings which are independently supplied with exciting current in a sequence of four states per step of the step motor. The driving circuit is capable of applying a large or a small current to each phase winding and the currents are applied in a sequence to result in a trapezoidal shaped exciting current. During a first state only one phase is excited and it is excited with the large current. During the second state the one phase is excited with the large current and the other phase with the small current. During the third state both phases are excited with large currents. During the fourth state the one phase is excited with the small current and the other phase with the large current.Type: GrantFiled: July 9, 1982Date of Patent: July 31, 1984Assignee: Fuji Xerox Co., Ltd.Inventors: Fujio Moriguchi, Tomio Murayama, Takashi Ohmori

Patent number: 4454516Abstract: A heat-sensitive recording apparatus includes a two-stage buffer memory for storing input video signals corresponding to one line, and a counter which determines the proportion of "black" signals in one line as the signals are input thereto. Whether printing of the line is to be carried out in one or plural operations is determined by the determined proportion, and a signal indicative of the number of operations is outputted to a block driver prior to the time when the corresponding video signals are outputted by the second stage of the buffer memory to a shift register.Type: GrantFiled: March 17, 1982Date of Patent: June 12, 1984Assignee: Fuji Xerox Co., Ltd.Inventors: Haruhiko Moriguchi, Takashi Ohmori, Toshiharu Inui
