Publication number: 20040184080Abstract: A schedule view is displayed in a print server. In the schedule view, print-jobs are displayed with rectangular shapes having lengths corresponding to printing time and color (or pattern) corresponding to its state, and the print-jobs are arranged and displayed in the order of prints to which the print-jobs are allocated. It is possible to intuitively grasp relative magnitude of a load of each printer by the length of a job graph, and an absolute amount of the load of each printer converted into a printing time by a displayed time scale. In addition to this, details of a job which is being processed, details of a selected job, and a state of each printer are also displayed.Type: ApplicationFiled: January 28, 2004Publication date: September 23, 2004Inventors: Tetsuya Gotoh, Hajime Takahashi, Keiji Yamamoto

Patent number: 6486419Abstract: An image forming apparatus having at least two of a plurality of functions including copying, facsimile and printer functions includes a main power switch that is provided on an outer surface of the apparatus and a cover to cover the main power switch. The cover is capable of opening and closing. Because the main power switch cannot be operated unless the cover is opened, when a user inadvertently tries to turn off the main power switch, for example, at the end of a day, the user must first touch the cover and is thereby reminded that the switch which the user is trying to turn off, is actually the main power switch for the apparatus. Thus, the main power switch is prevented from being inadvertently or unconsciously turned off.Type: GrantFiled: January 11, 1999Date of Patent: November 26, 2002Assignee: Ricoh Company, Ltd.Inventors: Shigeru Horiguchi, Yuki Nanri, Kazuyuki Saitoh, Yuji Suzuki, Masahiro Nakajima, Tetsuya Gotoh

Patent number: 6113094Abstract: An image forming apparatus which can control a number of paper sheets to be stacked onto a paper receiving tray based on a read paper sheet size. This structure is particularly relevant if a receiving paper tray is inclined and has an area above the paper receiving tray limited by a structure formed above the paper receiving tray. A height of stacked paper sheets on the paper receiving tray can be sensed, and a number of paper sheets allowed to be stacked on the paper receiving tray can be limited based on the read paper size and the sensed height of the stack of paper sheets. Further, the number of paper sheets allowed to be stacked onto the paper receiving tray can be limited based on the read paper size.Type: GrantFiled: November 30, 1998Date of Patent: September 5, 2000Assignee: Ricoh Company, Ltd.Inventors: Shigeru Horiguchi, Yuji Suzuki, Tetsuya Gotoh

Patent number: 6075958Abstract: An image forming apparatus which includes both a front cover and a side cover which must be opened to properly access an area where a paper jam may occur. The side cover includes an extending portion protecting board which extends into an area covered by the front cover. The protecting board prevents access to internal elements of the image forming apparatus which an operator may attempt to access if a paper jam occurs, without also opening the side cover. Thereby, an operator is required to properly open both the front cover and the side cover to address a paper jam situation.Type: GrantFiled: November 30, 1998Date of Patent: June 13, 2000Assignee: Ricoh Company, Ltd.Inventors: Tetsuya Gotoh, Yuji Suzuki, Masahiro Nakajima, Shigeru Horiguchi

Patent number: 5169986Abstract: The present invention provides an organic nonlinear optical material including a benzylidene-aniline derivative having an electron-donating substituent introduced at the 4-position and an electron-accepting substituent introduced at the 4'-position, by selecting as the conjugated .pi. electronic system a benzylidene-aniline derivative having a large molelcular hyperpolarizability and yet a dipole moment as small as those of benzene derivatives, and introducing a molecular alignment-regulating substituent. The centrosymmetry in the bulk state of the material, for example, in the crystal state, is destroyed and the molecular alignment is regulated to such a bulk structure so that the optical nonlinearity possessed by the molecule is effectively utilized. The material exhibit a large optical nonlinearity never attained by conventional techniques.the intermolecular cohesive force due to the .pi. electron interaction between the molecules in the present invention is larger than that between a benzene derivative.Type: GrantFiled: October 19, 1990Date of Patent: December 8, 1992Assignee: Toray Industries, Inc.Inventors: Tetsuya Tsunekawa, Tetsuya Gotoh, Keiichi Egawa
