Patent number: 10162290Abstract: To efficiently transmit drive through couplings on one and another sides during forward rotation and reverse rotation. When first and second couplings are brought into engagement with each other and rotated in a forward direction, first and third drive transmission surfaces are brought into contact with each other to be rotated in the forward direction while producing components of force in directions in which the first and second couplings are drawn to each other in the rotational axis direction. When the first and second couplings are brought into engagement with each other and rotated in a reverse direction, second and fourth drive transmission surfaces are brought into contact with each other to be rotated in the reverse direction without producing components of force in directions in which the first and second couplings are separated from each other in the rotational axis direction.Type: GrantFiled: November 12, 2015Date of Patent: December 25, 2018Assignee: Canon Kabushiki KaishaInventors: Chikara Imaizumi, Hiroyuki Matsumoto, Kazushi Suzuki, Hiroshi Kawamura

Publication number: 20180288255Abstract: An image forming apparatus includes an image reading unit, an original conveyance unit, a reversing unit, an image forming unit, an image forming conveyance unit, and a control unit. The original conveyance unit conveys an original in a first direction toward the image reading unit, which reads an image of the original. The reversing unit conveys an original passing through the image reading unit in the first direction, or reversely conveys the original toward the image reading unit in a second direction. The image forming unit forms an image on a sheet. The image forming conveyance unit conveys, to the image forming unit, an original reversely conveyed by the reversing unit via the image reading unit. The control unit controls an operation for reading an image of the original by using the image reading unit and for overprinting the original with an image by using the image forming unit.Type: ApplicationFiled: March 7, 2018Publication date: October 4, 2018Inventors: Yoshitaka Zaitsu, Kazushi Suzuki, Hideki Ohta, Tamotsu Kaneko

Patent number: 9395654Abstract: An image forming apparatus includes a lever configured to move a secondary transfer roller from an endless belt. The lever is arranged between a primary transfer surface of the endless belt, which opposes a plurality of image bearing members between an opposing roller and a stretching roller, and a surface opposing the primary transfer surface. The lever is engaged with the secondary transfer roller to separate the secondary transfer roller from the endless belt. Such a simple contact-separation configuration for the secondary transfer roller achieves reduction in size and space of the image forming apparatus.Type: GrantFiled: April 24, 2015Date of Patent: July 19, 2016Assignee: Canon Kabushiki KaishaInventors: Kazushi Suzuki, Chikara Imaizumi

Patent number: 9395648Abstract: In connection with movement of an opening-closing member when a toner accommodating container is attached to the image forming apparatus, the urging direction of an urging member relative to the opening-closing member changes from a direction that causes the opening-closing member to close an opening portion to a direction that causes the opening-closing member to open the opening portion. By using the urging force of the urging member that acts in the direction that causes the opening-closing member to open the opening portion, the toner accommodating container is pulled into the image forming apparatus.Type: GrantFiled: June 18, 2015Date of Patent: July 19, 2016Assignee: Canon Kabushiki KaishaInventor: Kazushi Suzuki

Publication number: 20160200912Abstract: Provided is a light-blocking pigment composition which has high insulation properties and a low dielectric constant and which can satisfy high optical density, and a light-blocking member for display, which contains the light-blocking pigment composition. When a pigment composition containing a benzimidazolone dioxazine-based pigment, a benzimidazolone-based pigment, and a carbazole dioxazine-based pigment in a specific ratio is used for a light-blocking member for display, since the light-blocking member has high insulation properties, a low dielectric constant, and high optical density, it is possible to provide a display having high light-blocking properties.Type: ApplicationFiled: December 18, 2014Publication date: July 14, 2016Applicant: DIC CorporationInventors: Kazushi SUZUKI, Ryosuke ASAMI, Ikuro KIYOTO

Patent number: 9298139Abstract: An image forming apparatus includes: a transfer unit including a stretching roller and a rotatable transfer belt stretched by the stretching roller; a cleaning unit, including a blade movable toward and away from the transfer belt, for collecting a toner removed from the transfer belt by the blade; a moving member for moving the blade between a contact position where the blade is contacted to the transfer belt and a retracted position where the blade is moved away from the transfer belt; and a drive transmission device for permitting transmission of a driving force between the stretching roller and the movable member. The drive transmission device has an idling region where the drive transmission device is rotatable by a predetermined amount without transmitting the driving force to the stretching roller when the driving force is transmitted from the moving member to the drive transmission device.Type: GrantFiled: March 26, 2015Date of Patent: March 29, 2016Assignee: Canon Kabushiki KaishaInventors: Yoshimi Suzuki, Chikara Imaizumi, Kazushi Suzuki
