Publication number: 20150293472Abstract: In an image forming apparatus, a sensing body is disposed at a first position when a cartridge has been removed from an apparatus body, is disposed at a second position when a first part of the sensing body contacts a housing of the cartridge that has been mounted in the apparatus body, and is disposed at a third position when a second part of the sensing body contacts a movable member of the cartridge that has been mounted in the apparatus body. A judging unit determines that the cartridge has been removed from the apparatus body if the sensing body is at the first position, determines that the cartridge has been mounted in the apparatus body if the sensing body is at the second position, and determines that the cartridge is a new product if the sensing body is at the third position.Type: ApplicationFiled: June 24, 2015Publication date: October 15, 2015Inventors: Tomitake Aratachi, Satoru Ishikawa

Patent number: 9069328Abstract: A cartridge may include a conveyor roller extending along a rotational axis and a bearing member for rotatably supporting the conveyor roller. The conveyor roller may include a larger-diameter portion for conveying a sheet, and a smaller-diameter portion. The bearing member may rotatably support the smaller-diameter portion of the conveyor roller, and engage the housing. In one or more arrangements, the entire smaller-diameter portion of the conveyor roller may be located at a more outward position, relative to a midpoint of the larger-diameter portion, than a portion of the bearing member supporting the smaller-diameter portion of the conveyor roller.Type: GrantFiled: July 17, 2014Date of Patent: June 30, 2015Assignee: Brother Kogyo Kabushiki KaishaInventors: Satoru Ishikawa, Keita Shimizu
