Patent number: 8755727Abstract: A surface processing apparatus includes a heater and a controller for controlling a heating of a sheet. The controller determines a difference between a position, on the sheet, of an image indicated by original image information and a position, on the sheet, of the actually formed image on the sheet indicated by outer configuration information of the sheet and the actual image information. The controller corrects inputted heating position information, for the heater, on the basis of information of the difference, and controls the heating of the heating means in accordance with the corrected heating position information.Type: GrantFiled: September 13, 2012Date of Patent: June 17, 2014Assignee: Canon Kabushiki KaishaInventor: Hideaki Kosasa

Patent number: 8185035Abstract: An image forming system which realizes reliable output of an original of a finished book, while maintaining security. A sheet-unique information-reading unit reads sheet-unique information unique to a sheet used for making a finished book based on image data. A memory section stores the sheet-unique information read by the sheet-unique information-reading unit in association with the image data based on which a finished book is made. In outputting an original of the finished book, a CPU causes an image forming device to perform image output based on the information stored in the memory section.Type: GrantFiled: May 13, 2008Date of Patent: May 22, 2012Assignee: Canon Kabushiki KaishaInventor: Hideaki Kosasa
