Publication number: 20120263495Abstract: An image forming apparatus includes an image bearing member for bearing a toner image, a developing device for supplying toner to a circumferential surface of the image bearing member, a toner container for supplying the toner to the developing device, a sheet conveyance path for conveying a sheet, and a housing. The housing accommodates the image bearing member, the developing device and the toner container. The housing has a first surface and a second surface different from the first surface. The toner container is taken out from the interior of the housing to the outside of the housing through the first surface. The developing device is taken out from the interior of the housing to the outside of the housing through the second surface.Type: ApplicationFiled: April 11, 2012Publication date: October 18, 2012Applicant: KYOCERA DOCUMENT SOLUTIONS INC.Inventors: Tamotsu Shimizu, Takahisa Nakaue, Takashi Morita, Teruhiko Nagashima

Publication number: 20120263503Abstract: A developing device includes a developer housing which includes a container mounting portion and a toner supply opening, a developer shutter plate which is so held on the developer housing as to be movable in a direction parallel to a developing roller and is displaceable to a closing position for closing the toner supply opening and an opening position, and a biasing spring which biases the developer shutter plate to the closing position. The container main body includes a first pressing plate and the developer shutter plate includes an oblique elongated projection with which the first pressing plate comes into contact. The first pressing plate and the oblique elongated projection are formed to displace the developer shutter plate from the closing position to the opening position against a biasing force of the biasing spring as the toner container moves in an assembling direction in a mounting process.Type: ApplicationFiled: April 12, 2012Publication date: October 18, 2012Applicant: KYOCERA DOCUMENT SOLUTIONS INC.Inventor: Teruhiko Nagashima

Publication number: 20120263504Abstract: A toner container includes container main body, conveying screws and container gear. A developing device includes developer housing including container mounting portion, gear holder including output gear which rotates upon receiving rotational drive force from motor and displaceable to engaged position where the output gear is engaged with the container gear and retracted position retracted outward from the engaged position, and biasing spring. The container main body includes a second pressing plate and the gear holder includes a contact portion with which the second pressing plate comes into contact. The second pressing plate and the contact portion displace the gear holder from the engaged position to the retracted position as the toner container moves in a mounting process. When the toner container reaches a predetermined assembled position, the gear holder is returned to the engaged position by a biasing force of the biasing spring.Type: ApplicationFiled: April 13, 2012Publication date: October 18, 2012Applicant: KYOCERA DOCUMENT SOLUTIONS INC.Inventor: Teruhiko Nagashima

Publication number: 20120263502Abstract: An image forming apparatus includes an image bearing member, a developing apparatus and a toner container which replenishes the developing apparatus with toner. The developing apparatus includes a first conveyance member having a first rotational shaft and a toner replenishment port. The toner container includes a second conveyance member having a second rotational shaft and a toner discharge port. The developing apparatus and the toner container are assembled in such a manner that the first rotational shaft and the second rotational shaft are in mutually perpendicular directions, and the toner replenishment port and the toner discharge port are mutually overlapping in a vertical direction. The second conveyance member rotates in a direction whereby the toner is discharged from the toner discharge port to the toner replenishment port at a position on an upstream side of the toner replenishment port in terms of the toner conveyance direction.Type: ApplicationFiled: April 12, 2012Publication date: October 18, 2012Applicant: KYOCERA DOCUMENT SOLUTIONS INC.Inventors: Takahisa NAKAUE, Takashi MORITA, Tamotsu SHIMIZU, Teruhiko NAGASHIMA

Publication number: 20090119084Abstract: A simulation system includes a Response database for storing Response Data in which an output result of a device-under-test (DUT) model for a predetermined test item is set, and a framework for causing the test plan program to operate. The framework determines an output result of a DUT or a DUT model for a predetermined test item, which is executed based on the test plan program, based on the Response Data stored in the Response database. That enables a test flow to be verified in an offline simulation environment of the test equipment without loading a pattern program.Type: ApplicationFiled: November 5, 2007Publication date: May 7, 2009Applicant: ADVANTEST CORPORATIONInventors: Teruhiko Nagashima, Hajime Sugimura

Patent number: 5696550Abstract: An image quality inspection system determines view angle dependent defects by capturing an LCD image viewed obliquely over the entire LCD panel while in focus. The system obtains the positions of each of the LCD pixels from the distorted screen as a CCD pixel address and captures the CCD image precisely. In a first embodiment, a second CCD camera has a built-in CCD area sensor and measures the contrast of the LCD obliquely. The second CCD camera has a built-in tilt lens system or a built-in shift lens systems which allows it to focus on the entire LCD panel plane.Type: GrantFiled: July 14, 1995Date of Patent: December 9, 1997Assignee: Advantest CorporationInventors: Hiroyuki Aoki, Yoshihisa Matsumura, Hiroto Satoh, Teruhiko Nagashima, Masaki Hayashi
