Patent number: 11766878Abstract: The apparatus includes a first ejection unit, a processing tray, a blower unit, a control unit, and a post-processing unit. The first ejection unit ejects a medium recorded by ejection of a liquid. On the processing tray, the medium ejected by the first ejection unit is stacked. The blower unit blows air to the medium stacked on the processing tray. The control unit controls the blower unit. The post-processing unit post-processes the medium stacked on the processing tray. Based on processing information about processing performed on the medium, the control unit changes a blowing amount at which the blower unit blows air.Type: GrantFiled: March 1, 2022Date of Patent: September 26, 2023Assignee: Seiko Epson CorporationInventor: Kei Sadakuni

Patent number: 11755861Abstract: A printing system includes a printing unit, a position determiner that randomly determines a position where a first information code is to be set, a modifier that modifies print data for printing an image, the first information code, and a positional information code having recorded therein positional information at the time of printing that indicates the position determined by the position determiner so that the first information code is set at the position determined by the position determiner, an acquirer that acquires the position of the first information code on a print medium as positional information and acquires the positional information at the time of the printing from the positional information code, and a determiner that determines whether the printing result is a falsified matter based on comparison of the positional information after the printing with the positional information at the time of the printing.Type: GrantFiled: August 17, 2022Date of Patent: September 12, 2023Assignee: Seiko Epson CorporationInventors: Kazuyoshi Ohashi, Shun Hara, Kenji Uchibori, Riku Maeda, Hirofumi Yanagisawa, Yu Tsumuraya, Kei Sadakuni

Patent number: 11713206Abstract: A medium loading device includes a side end aligning member which is positioned at a standby position when a medium is ejected; and a control section. When a value based on first information relating to recording density of a medium to be ejected this time and at least one medium among the media ejected previously is equal to or greater than a threshold value, the control section specifies a first position, which overlaps the medium to be ejected this time, as the standby position, and when the value based on the first information is less than the threshold value, the control section specifies a second position, which does not overlap the medium to be ejected this time, as the standby position, and the control section adjusts the threshold value based on second information relating to at least one medium among the media recorded before the ejection at this time.Type: GrantFiled: March 1, 2022Date of Patent: August 1, 2023Assignee: Seiko Epson CorporationInventors: Hirofumi Yanagisawa, Kazuyoshi Ohashi, Shun Hara, Kenji Uchibori, Kei Sadakuni

Publication number: 20230035111Abstract: A printing system includes an acquirer, a comparator, a calculator, and an allocator. The acquirer acquires the number of media printed by a first printing device installed at a first location. The comparator compares the number of printed media acquired by the acquirer with the number of media specified based on a billing amount. The calculator calculates a first number of printable media of the first printing device based on the comparison by the comparator. The allocator allocates at least a part of the first number of printable media calculated by the calculator as a second number of printable media to a second printing device installed at a second location. The second printing device can perform printing as a billing target based on the second number of printable media.Type: ApplicationFiled: July 28, 2022Publication date: February 2, 2023Inventor: Kei SADAKUNI

Patent number: 11505423Abstract: A loading unit includes a processing tray, alignment units, and a paddle. In the processing tray, a medium is placed. The alignment units are disposed an interval in a Y direction to align a downstream tip end in a positive A direction of the medium. The paddle moves the medium that has been fed onto the processing tray toward the alignment units. A coefficient of friction of a contact surface of the alignment unit is higher than a coefficient of friction of a front face of the alignment unit, and the contact surface is positioned downstream of the front face in the positive A direction.Type: GrantFiled: March 30, 2021Date of Patent: November 22, 2022Assignee: Seiko Epson CorporationInventors: Chiaki Shimada, Masaki Miyazawa, Kei Sadakuni, Hirohisa Kodaira

Patent number: 10343422Abstract: A recording apparatus includes a belt conveyor unit that can be switched between a first state in which at least a portion of the belt outer surface of a conveyor belt is located at a recording position at which a line head performs recording and a second state in which the belt outer surface is located more distant than the recording position from the line head. The recording apparatus also includes a wiping device that is in contact with the belt outer surface and wipes the belt outer surface. The belt conveyor unit is switched from the second state to the first state after carrying out of a preliminary operation in which the conveyor belt is moved over a predetermined distance in a reverse direction opposite to a normal direction in which the conveyor belt transports a sheet.Type: GrantFiled: February 14, 2018Date of Patent: July 9, 2019Assignee: Seiko Epson CorporationInventors: Kei Sadakuni, Satoshi Chiba, Nobuyuki Mizushima
