Patent number: 8422050Abstract: An apparatus is provided that can perform distributed control for a plurality of operation units, without concentrating control in a single device. The apparatus includes a plurality of modules that respectively correspond to a plurality of operation units, each module including a communication device, a functional block setting device and a functional block connected with a corresponding operation unit. The functional block has a register that holds, in an updateable condition, control values relating to various controls of the corresponding operation unit. Each module is triggered by an operation start signal input to a start terminal of the communication device to start an operation for controlling a corresponding operation unit in accordance with each control value held in the register device.Type: GrantFiled: March 16, 2006Date of Patent: April 16, 2013Assignee: Canon Kabushiki KaishaInventors: Toshihiko Kitahara, Junichi Into, Eiichi Motoyama, Masao Watanabe, Tsunao Hombo, Akihiko Sakai, Masatoshi Yaginuma

Patent number: 7751593Abstract: An image reading apparatus having a security function that realizes highly precise authentication and high operability while suppressing an increase in manufacturing cost. An original 10 is placed on a platen glass 12, and an authentication card 80 is placed on a security information reading section 101. An image sensor 25 reads an image of the original 10 placed on the platen glass 12 and security information stored in the authentication card 80 placed on the security information reading section 101. A control section 4 controls processing of the image of the original 10 read by the image sensor 25 in accordance with the security information read by the image sensor 25.Type: GrantFiled: June 30, 2005Date of Patent: July 6, 2010Assignee: Canon Kabushiki KaishaInventor: Tsunao Hombo
