Patent number: 7039928Abstract: The TV program table data in the area where a viewer resides are received through the Internet or a broadcasting medium by using the TV set with an internet connection function at the viewer. While the viewer is watching a TV program, the audience data including viewed channel information and viewed time information are automatically obtained. The obtained audience data are compared with the TV program table data to identify the watched program. The program ID of the identified program and the viewed time information are transferred to a data collecting center through the Internet together with the viewer ID data. By utilizing the Internet for the distribution of the TV program table data to the viewers and for the collection of the audience data, the nationwide TV audience data can be easily collected and used to make statistics. Since viewed channel and viewed time information are correlated with programs on the viewer's side, the load of processing the data on the center side can be relieved.Type: GrantFiled: December 12, 1997Date of Patent: May 2, 2006Assignees: Access Co., Ltd., Nippon Telegraph and Telephone CorporationInventors: Tomihisa Kamada, Takeshi Motohashi, Eiji Kuwana

Patent number: 6546228Abstract: An image forming apparatus includes a first sheet path, a first sheet transfer mechanism, an ejection mechanism, a second sheet path, and a sheet flipping mechanism. The first sheet path is in a first side of the image forming apparatus. The first sheet transfer mechanism sends recording sheets from a sheet cassette through the first sheet path. The ejection mechanism switches between an ejection process and a duplex recording process. The second sheet path receives the recording sheet from the ejection mechanism and returns it to the image recording mechanism. The second sheet path is on the other side of the apparatus than the first side in which the first sheet path is arranged. The sheet flipping mechanism flips the recording sheet and has a flipping space in which the recording sheet is flipped without coming outside of the image forming apparatus. The ejection mechanism, the second sheet path, and the sheet flipping mechanism are located in a separate add-on unit.Type: GrantFiled: January 11, 2001Date of Patent: April 8, 2003Assignee: Ricoh Company, Ltd.Inventors: Takeshi Motohashi, Masashi Takiguchi, Hirotaka Hatta, Katsuhiro Kosuge, Hideyuki Takemoto

Patent number: 6184910Abstract: A color image forming apparatus capable of superposing toner images of respective colors in accurate register by preventing an exposing position from being displaced in the subscanning direction. The rotation phase of a polygonal mirror is controlled on the basis of the mark detection timing of a mark sensor. Hence, the exposing position in the subscanning direction is prevented from being displaced without regard to irregularities in the circumferential length and feed speed of an intermediate image transfer belt.Type: GrantFiled: April 7, 1995Date of Patent: February 6, 2001Assignee: Ricoh Company, Ltd.Inventors: Eiichi Sasaki, Tsuyoshi Deki, Nobuo Iwata, Takeshi Motohashi, Takahiro Tamiya, Yutaka Shio, Tomonori Yabuta

Patent number: 5678161Abstract: In a paper conveyer of an image forming apparatus, a transfer operation is performed by a transfer roller and an unfixed image in the transfer operation is carried onto the lower side of a transfer paper sheet. The transfer paper sheet is conveyed to a fixing device constructed by a fixing roller and a pressurizing roller. A hardness of the fixing roller is smaller than that of the pressurizing roller, while a nipping portion of the fixing and pressurizing rollers is formed in a concave shape. The fixing and pressurizing rollers are arranged such that a nipping inlet port point of the fixing and pressurizing rollers is located in the vicinity of a line of a conveying locus of a thin transfer paper sheet. A paper guide plate guides the transfer paper sheet to the nipping inlet port. In this construction, a transferred paper sheet is conveyed such that this transferred paper sheet is reliably fed into the nipping portion of the fixing device, and it is possible to prevent an image rub, wrinkles, a jam, etc.Type: GrantFiled: February 1, 1996Date of Patent: October 14, 1997Assignee: Ricoh Company, Ltd.Inventors: Shigeo Kurotaka, Nobuo Iwata, Shingo Katou, Takeshi Motohashi, Tsuyoshi Deki, Takahiro Tamiya, Tomonori Yabuta

Patent number: 5599645Abstract: In an image forming apparatus of the type sequentially forming powder images of different colors on an image carrier, and sequentially transferring them to an acceptor one above the other (primary transfer), an image transfer method is disclosed which prevents transfer dust from being transferred to the acceptor at the time of the primary transfer. During the primary transfer, a bias potential V.sub.1 is applied to one of two conductors located at an upstream side. The potential V.sub.1 has the same polarity as the charged powder carried on the image carrier. A potential V.sub.2 is applied to the other conductor at a downstream side and provided with a polarity opposite to the polarity of the charged powder. Every time the primary transfer is repeated, the potentials V.sub.l and V.sub.2 are respectively sequentially shifted toward the polarity of the powder and toward the polarity opposite to the polarity of the powder.Type: GrantFiled: May 11, 1995Date of Patent: February 4, 1997Assignee: Ricoh Company, Ltd.Inventors: Takahiro Tamiya, Nobuo Iwata, Tsuyoshi Deki, Takeshi Motohashi

Patent number: 5389733Abstract: A developing device which is particularly advantageous from the standpoint of avoiding leakage or scattering of toner. The developing device is additionally advantageous in allowing for a compact design while reliably supplying toner to the complete area of a photosensitive member upon which a latent image is formed. The developing device includes a toner container having an opening in a lower part thereof, through which toner falls. A magnet bar is provided below the opening, with a developing grid covering a portion of the magnet bar. The magnet bar forms a magnetic toner brush which penetrates through holes in the developing grid, with the magnetic toner brush and grid cooperating to prevent excessive toner from falling through the opening and thus preventing excessive toner from scattering outside the developing device.Type: GrantFiled: February 28, 1994Date of Patent: February 14, 1995Assignee: Ricoh Company, Ltd.Inventors: Shigekazu Enoki, Yoshiaki Tanaka, Takeshi Motohashi, Fumihiro Kitahara, Koyo Hariyama
