Patent number: 6985684Abstract: An image forming apparatus where during the image forming operation, the completion of development by one of development cartridges is followed by the rotation of a rotary for setting the next development cartridge to a development position. The rotational speed v of the rotary is increased linearly to the maximum speed vmax and, after that, is decreased linearly to stop the rotary when the next development cartridge reaches the development position. During replacement of the development cartridge, the rotary is rotated to set the development cartridge to be replaced to the replacement position. The rotational speed of the rotary is set to be a constant speed v1 in a region other than a contact region where an input gear of the development side is in contact with a driving gear of the fixed side and a speed lower than the speed v1 in the contact region (the minimum speed v2).Type: GrantFiled: August 28, 2003Date of Patent: January 10, 2006Assignee: Seiko Epson CorporationInventors: Yasuhiro Matsuo, Satoru Miyamoto, Minoru Kishigami

Patent number: 6963710Abstract: A rotary developing apparatus having a plurality of developing devices mounted along the outer periphery of a cylindrical rotary unit. A first gear train for connecting the rotary unit to a drive source to rotate the rotary unit. A second gear train for connecting a developing roller of a developing device revolved and stopped at a developing position, as a result of the rotary unit being rotationally driven, to the drive source to rotate the developing roller. The rotary unit and the developing roller are rotated with the same motor used as the drive source by switching between the connections of the gear trains, thereby rapidly damping vibration generated by the rotation of the rotary unit and vibration generated by the rotation of the developing roller, and thus eliminating image defects due to displacement, etc.Type: GrantFiled: January 20, 2004Date of Patent: November 8, 2005Assignee: Seiko Epson CorporationInventors: Minoru Kishigami, Yasuhiro Matsuo, Satoru Miyamoto

Publication number: 20040041821Abstract: An UI section accepts operation of a user. A setting selection section judges as to whether this user operation instructs a process operation executed in accordance with setting information of an IC chip attached to an original document, or another process operation executed in accordance with setting information entered by the user. In the former case, an operation control section controls a data reading section so as to read out the setting information from the IC chip attached to the original document, and also, controls a print control section to perform printing/FAX transforming operations in accordance with this read setting information. In the latter case, an operation control section controls a data writing section in order to write the setting information entered by the user into the IC chip.Type: ApplicationFiled: August 26, 2003Publication date: March 4, 2004Applicant: FUJI XEROX CO., LTD.Inventors: Ryoji Watanabe, Akihiko Takada, Masayoshi Sakakibara, Hajime Kishimoto, Yasuo Horino, Toshiyuki Yano, Yasuhiro Matsuo
