Publication number: 20220373859Abstract: A rotatable operation apparatus includes a rotatable operation member, a magnet having alternately magnetized magnetic poles, first and second magnetic members respectively including first and second teeth, a body frame, and a detector. A magnetized direction of each magnetic pole is parallel to a predetermined axis about which the rotatable operation member rotates. The magnet has a ring shape and is configured to rotate about the predetermined axis as the rotatable operation member rotates. The rotatable operation apparatus generates an operation force according to a change in positions of the magnetic poles, caused by the rotation of the magnet, relative to positions of the first tooth and the second tooth. The magnet, the first magnetic member, and the second magnetic member are housed inside the body frame. When viewed from a thrust direction of the magnet, the detector is disposed at a position that does not overlap with the magnet.Type: ApplicationFiled: May 13, 2022Publication date: November 24, 2022Inventors: Sho Nagatsu, Jun Kamiya, Shogo Satomura, Yoshikazu Asai, Takahiro Akimoto

Image forming apparatus with frame body and detachable cartridge with integrated photosensitive drum
Patent number: 10048646Abstract: A structure includes a rotatable rotating member, a blade, a support member, and a frame body. The blade extends in an axial direction of the rotating member and is in contact with or disposed close to a surface of the rotating member. The support member supports the blade such that one end side of the blade projects toward the rotating member in a lateral direction that intersects the axial direction. The frame body is formed by insert molding in which resin is injected while the support member is secured to a mold. The frame body clamps part of the support member so as to support the support member.Type: GrantFiled: June 12, 2015Date of Patent: August 14, 2018Assignee: Canon Kabushiki KaishaInventors: Akira Suzuki, Hiroomi Matsuzaki, Kazunori Suzuki, Toshiteru Yamasaki, Shigeo Miyabe, Takahito Ueno, Shogo Satomura, Masatomi Yoshida, Nobuharu Hoshi -
Publication number: 20180046136Abstract: To provide a structure that includes a small number of components, that is unlikely to be affected by heat, and that allows a blade secured to a frame body and a rotating member to be in contact with each other at a uniform pressure in a longitudinal direction. A structure includes a rotatable rotating member, a blade, a support member, and a frame body. The blade extends in an axial direction of the rotating member and is in contact with or disposed close to a surface of the rotating member. The support member supports the blade such that one end side of the blade projects toward the rotating member in a lateral direction that intersects the axial direction. The frame body is formed by insert molding in which resin is injected while the support member is secured to a mold. The frame body clamps part of the support member so as to support the support member.Type: ApplicationFiled: June 12, 2015Publication date: February 15, 2018Inventors: Akira Suzuki, Hiroomi Matsuzaki, Kazunori Suzuki, Toshiteru Yamasaki, Shigeo Miyabe, Takahito Ueno, Shogo Satomura, Masatomi Yoshida, Nobuharu Hoshi
