Patent number: 11644668Abstract: A laser scanning device includes a polygon mirror, one or more lenses, and a plurality of light shielding plates. The polygon mirror reflects a light beam during rotation of the polygon mirror. The lenses allow the light beam reflected off the polygon mirror to pass through the lenses. The plurality of light shielding plates are arranged at a distance from each other and block an undesirable beam, which is part of the light beam, reflected off at least one of the lenses and heading for an optical device. The plurality of light shielding plates form an air channel that allows an air current generated by the rotation of the polygon mirror to flow through the air channel.Type: GrantFiled: August 17, 2021Date of Patent: May 9, 2023Assignee: KYOCERA Document Solutions Inc.Inventor: Daisuke Mimura

Patent number: 10698345Abstract: An image forming apparatus includes a drum unit, a process frame, a lock member and an intermediate transferring unit. The drum unit rotatably supports a rotating shaft of a photosensitive drum. The process frame has an attachment part to which the drum unit is attached. The lock member positions the drum unit to the attachment part. The intermediate transferring unit is attached to the process frame after the drum unit is attached. The lock member has a supporting part, an engagement part and a restriction part. Though the supporting part, an end of the rotating shaft is passed. The engagement part is engaged with the process frame between the process frame and the intermediate transferring unit. The restriction part interferes with the intermediate transferring unit between the engagement part and the intermediate transferring unit to prevent the engagement part from being detached from the process frame.Type: GrantFiled: May 8, 2017Date of Patent: June 30, 2020Assignee: KYOCERA Document Solutions Inc.Inventors: Daisuke Mimura, Hiromu Matsumoto

Patent number: 10474065Abstract: A toner case includes a case main body, a rotator, a transmitter and a cover. The case main body stores a toner. The rotator is stored in the case main body and rotates around a rotation axis. The transmitter transmits rotation to the rotator. At least apart of the transmitter is arranged outside the case main body. The cover moves along a rotation axis direction of the rotator between a covering position where the cover covers an outer circumference of the transmitter and an exposing position where the cover exposes the transmitter.Type: GrantFiled: December 29, 2017Date of Patent: November 12, 2019Assignee: KYOCERA Documents Solutions Inc.Inventor: Daisuke Mimura

Patent number: 10444670Abstract: A toner case includes a case main body, a rotator, a transmitter, a moving mechanism and a manipulation member. The rotator rotates around a rotation axis. At least a part of the rotator is stored in the case main body. The transmitter is arranged outside the case main body and transmits rotation to the rotator. The manipulation member is arranged outside the case main body. As the manipulation member moves from a first manipulating position to a second manipulating position, the moving mechanism moves the transmitter from a first position to a second position which is arranged at an outside of the first position in a rotation axis direction of the rotator. As the manipulation member moves from the second manipulating position to the first manipulating position, the moving mechanism moves the transmitter from the second position to the first position.Type: GrantFiled: December 8, 2017Date of Patent: October 15, 2019Assignee: KYOCERA Document Solutions Inc.Inventor: Daisuke Mimura
