Patent number: 8111420Abstract: A printer control apparatus can be applied to an image forming apparatus in which a plurality of types of readers and a plurality of types of printers can be connected to a single controller, and which enables efficient transfer of image data from the reader to the printer via an image memory of the controller. The controller receives image data from a reader and temporarily stores the same in an image memory, and transmits the stored image data to a printer. The controller acquires a reader processing speed from the reader and a printer processing speed from the printer, and determines, while the image data is being written to the image memory, timing for transmitting the image data written in the memory to the printer according to a difference between the reader processing speed and the printer processing speed and a sub-scan size of the image data.Type: GrantFiled: September 21, 2009Date of Patent: February 7, 2012Assignee: Canon Kabushiki KaishaInventors: Nobuo Sekiguchi, Masahiro Serizawa, Yoshihito Osari, Akinobu Nishikata

Patent number: 7835685Abstract: An image forming apparatus capable of reducing a part of a sheet exposed outside the apparatus on standby after finishing printing a first side in both-sided printing. A transfer material P having an image formed on its first side is fed until a part thereof gets exposed outside a full-color printer 1 and is fed to a refeeding path in the full-color printer 1. The transfer material P inverted by a flapper 44 is fed to a standby position to form an image on a second side thereof and is stopped there. In the case where a preparation for forming the image on the second side is not completed, the standby position for having the transfer material P stopped is changed corresponding to length of the inverted transfer material P in a feeding direction.Type: GrantFiled: May 30, 2006Date of Patent: November 16, 2010Assignee: Canon Kabushiki KaishaInventors: Yoshihito Osari, Eiichi Motoyama, Kuniyasu Kimura, Hiroaki Tomiyasu, Takahiko Yamaoka, Yuichi Yamamoto

Patent number: 7731093Abstract: An RFID tag formed on an original includes a storage unit which stores data representing, e.g., the number of times of scan of the original and the generation from a parent original, and a transmitter/receiver which transmits and receives the data by radio. A read/write circuit receives data from an RFID tag of an original by radio. On the basis of the received data, read of the original is controlled. While the original is being read, the received data is edited in accordance with the control. The read/write circuit transmits and writes the edited data in the RFID tag.Type: GrantFiled: July 28, 2004Date of Patent: June 8, 2010Assignee: Canon Kabushiki KaishaInventors: Keizo Isemura, Toshio Hayashi, Mitsushige Murata, Masatoshi Tanabe, Junichi Intoh, Yoshihiro Funamizu, Yoshihito Osari
