Publication number: 20230311545Abstract: An image forming apparatus includes a first sheet cassette, a first transport route, an image forming device, and a second transport route. The first sheet cassette is for storing therein a sheet. Along the first transport route, the sheet delivered from the first sheet cassette is transported. The image forming device forms an image based on image data, on the sheet transported along the first transport route. The second transport route communicates with outside of the image forming apparatus, and a sheet inserted by a user from outside is transported along the second transport route, to the image forming device. The second transport route is formed so as to circumvent a region between the image forming device and the first sheet cassette.Type: ApplicationFiled: March 24, 2023Publication date: October 5, 2023Applicant: KYOCERA Document Solutions Inc.Inventor: Kei WAKAYAMA

Patent number: 10222739Abstract: An image forming apparatus includes a housing, an attachable and detachable device, a cover member, and a rotation angle restricting member. The housing has an opening and an attachment section. The attachable and detachable device is attachable to and detachable from an inside of the housing via the opening. The cover member is rotatably supported by the housing and closes or opens the opening. The rotation angle restricting member restricts an allowable rotation angle that indicates an angle at which the cover member is rotatable. The rotation angle restricting member is attachable to and detachable from the attachment section. The allowable rotation angle of the cover member is restricted when the rotation angle restricting member is attached to the attachment section. Restriction of the allowable rotation angle of the cover member is released when the rotation angle restricting member is detached from the attachment section.Type: GrantFiled: February 26, 2018Date of Patent: March 5, 2019Assignee: KYOCERA Document Solutions Inc.Inventor: Kei Wakayama

Patent number: 9261820Abstract: A cleaning device includes a cleaning portion, a polishing roller, a layer thickness restricting member, and a swaying portion. The cleaning portion removes toner that has adhered to a surface of a rotation body. The polishing roller polishes a surface of the rotation body by rotating in a state where a surface of the polishing roller is in contact with the surface of the rotation body and the toner removed by the cleaning portion has adhered to the surface of the polishing roller. The layer thickness restricting member restricts a layer thickness of the toner that has adhered to the surface of the polishing roller. The swaying portion includes a biasing portion, an undulating portion and a support portion, and causes the polishing roller to sway in an axis direction of the rotation body.Type: GrantFiled: March 19, 2015Date of Patent: February 16, 2016Assignee: KYOCERA Document Solutions Inc.Inventor: Kei Wakayama

Patent number: 8699934Abstract: A cleaning mechanism includes a rubbing roller, a bearing, a toner amount restricting plate, and a bracket. The rubbing roller is abrasively contacted with the surface of a photosensitive drum. The bearing rotatably supports the rubbing roller. The toner amount restricting plate restricts the amount of toner adhered to the surface of the rubbing roller. The bracket holds the toner amount restricting plate in a state that the toner amount restricting plate is contacted with the rubbing roller. The bracket has a bearing holding portion which holds the bearing, and a toner amount restricting plate mounting portion to which the toner amount restricting plate is fixedly mounted. The bearing holding portion and the toner amount restricting plate mounting portion continue to each other via a first bent portion.Type: GrantFiled: June 7, 2012Date of Patent: April 15, 2014Assignee: Kyocera Document Solutions Inc.Inventor: Kei Wakayama
