Patent number: 7454507Abstract: Upon reception of a data transmission request, an image input device 1 searches for transmission means available for transmission to a destination, such as transfer to FTP server or transmission by e-mail, and lists all the extracted available transmission means. Image input device 1 then creates a selection menu executed as an applet for receiving a selection of transmission methods from the destination. The destination can use the selection menu acquired from image input device 1 to designate the priority order of desired transmission means and a file name in reception of transmitted data. The selection menu thus created is transmitted to the image input device 1.Type: GrantFiled: June 2, 2003Date of Patent: November 18, 2008Assignee: Minolta Co., Ltd.Inventors: Hironobu Nakata, Takeshi Morikawa, Tatsuya Tanigawa, Kiyoshi Emori

Patent number: 5229812Abstract: An electric stapler is disposed at the bottom of a tray on which printed sheets are stacked, and is movable along the bottom of the tray. Printed sheets are aligned on the tray along a reference line. The stapler moves along the bottom of the tray and stops at determined points to staple the aligned sheets. A control section is stored with data about the number and location of stapling points proper for each sheet size. The size of printed sheets to be stapled is detected, and the movement of the stapler is controlled so that the stapler can staple at proper points for the detected sheet size.Type: GrantFiled: May 15, 1992Date of Patent: July 20, 1993Assignee: Minolta Camera Kabushiki KaishaInventors: Osamu Toyama, Kadotaro Nishimori, Toru Okatani, Tatsuya Tanigawa
