Publication number: 20140253655Abstract: An image forming apparatus and an image forming method are provided. The image forming apparatus includes a conveyer belt, a print head, a cutter, at least first and second rollers, and a controller. The conveyer belt conveys print media. The print head prints an image on the print media conveyed by the conveyer belt. The cutter is disposed downstream of the print head to cut the print media. The rollers are serially arranged between the print head and the cutter, and are configured to rotate the conveyer belt in the conveyance direction to convey the print media toward the cutter. The controller individually controls rotation speeds of the rollers to create a difference in rotation speed between the first and second rollers sufficient to make the print media bend between the first and second rollers while the cutter cuts.Type: ApplicationFiled: February 20, 2014Publication date: September 11, 2014Applicant: RICOH COMPANY, LTD.Inventors: Noriyuki SAI, Kazuyoshi MATSUMOTO

Patent number: 8134737Abstract: The printing apparatus of the present invention comprises a scanner unit for reading an image in an original; an instruction unit for receiving an instruction from a user and instructing operation of reading the image with the scanner unit; and a printer unit for printing the image that has been read on a medium. In the printing apparatus of the present invention, each reading operation with the scanner unit is started by receiving an instruction from the user with the instruction unit when the reading operation is to be performed with the scanner unit for a plurality of number of times and a plurality of the images that have been read are to be printed in their respective predetermined positions on the medium. The printing apparatus makes it possible to perform N-up printing of a new procedure that is different from conventional N-up printing.Type: GrantFiled: June 15, 2009Date of Patent: March 13, 2012Assignee: Seiko Epson CorporationInventors: Noriyuki Sai, Yasuhiro Oshima, Yoshihisa Motominami, Tomohiro Takahashi
