Patent number: 10805485Abstract: An image forming apparatus includes: a sheet tray; a sheet detection sensor that detects that a sheet is placed on the sheet tray; a display unit; and a control unit. In a case where the sheet detection sensor detects the sheet on the sheet tray, the control unit determines whether or not to cause the display unit to display a confirmation screen for sheet setting. In a case where a predetermined inappropriate confirmation condition is satisfied, the control unit causes the display unit not to display the confirmation screen. In a case where the inappropriate confirmation condition is not satisfied, the control unit causes the display unit to display the confirmation screen.Type: GrantFiled: December 18, 2018Date of Patent: October 13, 2020Assignee: SHARP KABUSHIKI KAISHAInventors: Nobuyasu Yamada, Takashi Nakagawa, Nobuyuki Ueda, Yuki Watanabe, Masaya Asakawa, Takashi Sawano, Kumiko Ogino

Patent number: 10666829Abstract: An image scanning device includes a platen, an image scanning unit that scans at a single time documents placed on the platen and generates pieces of image data, and an image data processing unit that performs processing of the pieces of image data. When the image scanning unit generates pieces of first image data by scanning first surfaces of the documents, each of which is placed in one of predetermined areas on the platen, and generates pieces of second image data by scanning surfaces opposite to the first surfaces of the documents, each of which is turned over and placed again in the one of the predetermined areas, the image data processing unit associates one of the pieces of the first image data with a corresponding one of the pieces of the second image data for each of the predetermined areas, as image data of the front and back surfaces.Type: GrantFiled: December 5, 2019Date of Patent: May 26, 2020Assignee: SHARP KABUSHIKI KAISHAInventors: Masaya Asakawa, Yohichi Tomota, Yuki Watanabe
