Patent number: 11815829Abstract: An image forming apparatus includes a first moving member moving between a first position which is a position not in contact with a recording material and a second position which is a position in contact with the recording material, and a second moving member positioned in a third position in a state where an attachable/detachable unit is not attached to an apparatus main body and in a fourth position in a state where the attachable/detachable unit is attached to the apparatus main body. An optical sensor includes a light-emitting portion and a light-receiving portion, and a flag member moves between a transmission position and a light-shielding position and moves in conjunction with movement of the first moving member from the first position to the second position and with a movement of the second moving member from the third position to the fourth position.Type: GrantFiled: September 13, 2022Date of Patent: November 14, 2023Assignee: CANON KABUSHIKI KAISHAInventors: Atsushi Oguni, Tetsuji Suzuki, Takuji Uesugi

Patent number: 11474449Abstract: An image forming apparatus includes a cartridge including an abutting portion and an apparatus main body. The apparatus main body includes a mounting portion of the cartridge, a fixing portion for fixing the toner image, an attachable/detecting mechanism of the cartridge, a shutter, and a moving member. The attachable/detecting mechanism includes an acting member movable between a first position and a second position by the mounting of the cartridge. The shutter is movable between a closed position and an open position, and a moving member moves both the shutter and the acting member and includes an abutted portion. When the cartridge is moved, the moving member is moved by abutment of the abutting portion of the cartridge with the abutted portion, the acting member moves from the first position to the second position, and the shutter moves from the closed position to the open position.Type: GrantFiled: June 7, 2021Date of Patent: October 18, 2022Assignee: CANON KABUSHIKI KAISHAInventors: Atsushi Oguni, Tetsuji Suzuki, Takuji Uesugi

Patent number: 11022202Abstract: A driving force transmission mechanism include a carrier, an input gear, first gears, second gears, an output gear, a clutch portion configured to integrate one of the input and output gears with the carrier or configured to disintegrate the one gear and the carrier, and an actuator configured to restrict rotation of the clutch. When the actuator does not restrict the rotation of the clutch portion, the input gear, the first gears, the second gears and the output gear are integrated with each other, and the output gear is rotated together with the input gear in a first direction. When the actuator restricts the rotation of the clutch portion, a rotational driving force is transmitted from the input gear to the output gear via the first gars and the second gears, and the output gear is rotated in a second direction opposite to the first direction.Type: GrantFiled: July 13, 2017Date of Patent: June 1, 2021Assignee: Canon Kabushiki KaishaInventor: Takuji Uesugi

Patent number: 10189644Abstract: Provided is a driving force transmission device including: an actuator (22) that, in a case where one of a first annular gear (11), a second annular gear (14), and a carrier (16) is an input member, another one is an output member, and the remaining one is a rotational member, causes one of the input member and the output member to rotate integrally with the rotational member. When driving force is inputted from the drive source to the input member and input member is rotated unidirectionally, the rotation direction of the output member in the case where one of the input member and the output member rotates integrally with the rotational member is reversed with respect to that in a case where one of the input member and the output member does not rotate integrally with the rotational member.Type: GrantFiled: August 22, 2017Date of Patent: January 29, 2019Assignee: Canon Kabushiki KaishaInventors: Takuji Uesugi, Yuji Nakayashiki, Taku Fukita, Akira Kuroda, Masao Umezawa, Yoshihiro Matsuo
