Patent number: 11899387Abstract: In an image-forming device, a drum cartridge and a developing cartridge are detachably attached to a frame. A controller is configured to perform: a drum replacement necessity determination process; and a mode switch process. The drum replacement necessity determination process determines, based on life information for the drum cartridge, whether replacement of the drum cartridge is necessary. The mode switch process switches a mode of a printing process between a normal printing mode and an extended printing mode. The normal printing mode allows the image-forming device to perform the printing process when the replacement of the drum cartridge is determined to be unnecessary. The extended printing mode allows the image-forming device to perform the printing process on a condition that the developing cartridge attached to the frame is not replaced with another developing cartridge in a state where the replacement of the developing cartridge is necessary.Type: GrantFiled: July 8, 2021Date of Patent: February 13, 2024Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventors: Tadao Kyotani, Takashi Suzuki, Shingo Fujiwara, Nao Itabashi

Publication number: 20140149938Abstract: The display device is composed of at least a data processor and a display. The blood analyzer is composed of the display device. The display method is performed using the display device. The data processor is composed to define a display-condition range corresponding to the range between the lowest frequency and the highest frequency in the frequencies of respective dots in the data set, so that a user can input a display-condition value through an input means. Then, a dot having a frequency not less than a frequency corresponding to the input display-condition value is displayed as a scattergram on the display. As a result, the user can freely change the display-condition value through the input means, and change the dot display range of the scattergram accordingly.Type: ApplicationFiled: November 27, 2013Publication date: May 29, 2014Applicant: HORIBA, Ltd.Inventors: Masashi Nishimori, Kyosuke Nakajima, Shingo Fujiwara

Patent number: 8717646Abstract: An image reading device conveys a first sheet and second sheet in a conveying direction. The first sheet has short sides extending in the conveying direction and long sides extending in a main scanning direction. The second sheet has long sides extending in the conveying direction and short sides extending in the main scanning direction. The image reading device reads an image on a sheet at a reading position and detects the sheet at a detecting position. A distance between the reading position and the detecting position is smaller than a difference between the short side of first sheet and the long side of second sheet. The image reading device rotates the read image if a sheet is not detected when the predetermined length worth of image is read. The read image is not rotated if a sheet is detected when the predetermined length worth of image is read.Type: GrantFiled: March 13, 2013Date of Patent: May 6, 2014Assignee: Brother Kogyo Kabushiki KaishaInventor: Shingo Fujiwara

Patent number: 8636276Abstract: An image reading device includes a sheet tray, a conveying unit, a reading unit, a detecting unit, and a control unit. The conveying unit conveys the sheet along a conveying path in a conveying direction. The reading unit reads the sheet at a reading position in a main scanning direction orthogonal to the conveying direction. The control unit controls the reading unit to start reading the sheet when the detection unit detects that a leading edge of a sheet reaches a position upstream of the reading position by a first distance. The control unit controls the reading unit to stop reading the sheet when the detection unit detects that a trailing edge of the sheet reaches a position downstream of the reading position by a second distance. The first distance and the second distance are determined according to the size of the sheet.Type: GrantFiled: September 14, 2012Date of Patent: January 28, 2014Assignee: Brother Kogyo Kabushiki KaishaInventor: Shingo Fujiwara
