Patent number: 6272248Abstract: An original image comprises a printed region on which a predetermined printed matter is realized and a background region on which no printed matter is realized. The shape of a peripheral zone in the original image comprises the shape of the background region, which shape exists particularly at the peripheral region of said original image. It is determined whether or not the original image comprises the special document by detecting the peripheral zone. Further, the original image has an outer-frame region, having a predetermined shape at the peripheral region of the original image. The determination is carried out using a result of measuring the width of the outer-frame region. Further, the width of the outer-frame region comprises a width along a direction substantially perpendicular to a direction extending along the outline of the original image.Type: GrantFiled: March 2, 1998Date of Patent: August 7, 2001Assignee: Ricoh Company, Ltd.Inventors: Takashi Saitoh, Hiroshi Takahashi, Yoshio Kaneko, Shigeo Kurotaka, Toshiya Hikita, Kyoji Omi, Midori Aida, Shinji Yamakawa, Hiromi Okubo, Kouji Ishigaki, Takeshi Ukai, Kazuo Murai, Haruhiko Fukuda, Yukio Sakano, Tadato Hashiguchi, Michiyoshi Tachikawa, Hiroyasu Sumida

Patent number: 4350750Abstract: Either a single copy or a plurality of copies of an original document may be made. Making a single copy or the last copy of a plurality of copies comprises, during a first revolution of a photoconductive drum, electrostatically charging the drum, radiating a light image of the document onto the drum to form an electrostatic image, developing the electrostatic image using a magnetic brush to form a toner image, transferring the toner image to a copy sheet, electrostatically discharging the drum and uniformly radiating the drum with light to further discharge the same. During a second revolution of the drum the drum is cleaned with the same magnetic brush to remove residual toner, and again electrostatically discharged and uniformly radiated. During a third revolution of the drum the magnetic brush is again used for cleaning.Type: GrantFiled: August 14, 1980Date of Patent: September 21, 1982Assignee: Ricoh Company, Ltd.Inventors: Shigeru Suzuki, Minoru Suzuki, Koichi Suzuki, Kyoji Omi, Yasumori Nagahara, Yoshiharu Kagari, Makoto Hashimoto, Goro Mori

Patent number: 4009957Abstract: As a scanning element of an electrophotographic copying machine begins to move, a feed roller moves a sheet of copy paper into the bite of register rollers which are held stationary. This movement of the copy paper is accomplished in a period of time which is less than that required for the scanning element to reach a predetermined scan synchronizing point. The feed roller is then stopped so that the copy paper is slightly buckled and thereby resiliently urged into the bite of the register rollers. When the scanning element reaches the scan synchronizing point, a sensor causes the register rollers to rotate thereby feeding the copy sheet through the machine in synchronization with the movement of the scanning element. The copy machine may employ a seamless photoconductive drum or belt moving at constant speed in which case an electrostatic image is formed on the drum or belt by the scanning element. The image is developed by toner particles and transferred to the copy sheet.Type: GrantFiled: November 7, 1974Date of Patent: March 1, 1977Assignee: Ricoh Co., Ltd.Inventors: Shigeru Suzuki, Minoru Iwamoto, Koichi Noguchi, Kyoji Omi, Tatsuo Nishikawa
