Publication number: 20210070073Abstract: An attachment structure includes: a shaft part via which a plate-like member is supported on a body in a manner capable of being opened and closed; a torsion spring to be fitted on the shaft part exposed in an open state, the torsion spring generating a damping force when the plate-like member is brought to the open state; a temporarily fixing groove extending along the shaft part and into which a one-end portion of the torsion spring fitted on the shaft part is inserted to temporarily fix the torsion spring to the body; and a bracket that is fixed to the body in the open state and presses the one-end portion of the torsion spring. The plate-like member has a gap in which, in a closed state, the torsion spring can be moved along the shaft part so that another-end portion of the torsion spring is inserted into an insertion hole in the plate-like member.Type: ApplicationFiled: March 24, 2020Publication date: March 11, 2021Applicant: FUJI XEROX CO., LTD.Inventors: Yoichi YAMAKAWA, Shumpei NOZAWA

Publication number: 20200264545Abstract: An image forming apparatus includes a recording material loading unit, a transport unit, a detector, and a controller. A recording material is loaded in the recording material loading unit. The transport unit transports the recording material from the recording material loading unit to an image forming unit that forms an image on the recording material. The detector detects a transport state of the transported recording material on a way from the recording material loading unit to the image forming unit. The controller performs control to change a position in which a user is prompted to check the transport state of the recording material and display a countermeasure method, based on a determination criterion that is determined according to (i) the transport state of the recording material detected by the detector and (ii) recording material information on the recording material.Type: ApplicationFiled: August 8, 2019Publication date: August 20, 2020Applicant: FUJI XEROX CO., LTD.Inventors: Eiichiro YAMAGUCHI, Yoichi Yamakawa, Keita Mizukoshi

Patent number: 9242821Abstract: A transport device includes an abutting member that abuts a leading end of a transport object and transport members that are disposed upstream of the abutting member in a transport direction and transport the transport object to the abutting member. The transport object is a first or second transport object. One of the transport members or the transport members transport the first transport object and cause the leading end of the first transport object to abut the abutting member. When transporting the transport object to a position where the leading end of the transport object abuts the abutting member, a transport force required to transport the second transport object is larger than that required to transport the first transport object. A larger number of transport members are used to transport the second transport object than the number of the transport members used to transport the first transport object.Type: GrantFiled: April 21, 2014Date of Patent: January 26, 2016Assignee: FUJI XEROX CO., LTD.Inventors: Kiyoshi Watanabe, Naohito Otsuki, Yoichi Yamakawa, Mizuki Arai

Patent number: 9242824Abstract: A transport mechanism includes a guide member that guides a transport object, which has a leading end and a trailing end, to be transported. The guide member includes a curved portion that is a curved portion of the guide member. The transport mechanism also includes a transport member that is disposed downstream of the curved portion in a transport direction in which the transport object is transported along the guide member, transports the transport object, and moves the transport object in an intersecting direction that intersects the transport direction. In the transport mechanism, when a length of the transport object in the transport direction is equal to or greater than a predetermined specified length that is greater than a distance between the transport member and the curved portion, the transport member does not move the transport object in the intersecting direction.Type: GrantFiled: May 14, 2014Date of Patent: January 26, 2016Assignee: FUJI XEROX CO., LTD.Inventors: Mizuki Arai, Naohito Otsuki, Kiyoshi Watanabe, Yoichi Yamakawa

Patent number: 7922973Abstract: A combined unit of a humidity indicator and a desiccant pack is provided in which the humidity indicator (I) has one end portion bonded to one end portion of the desiccant pack (D) and can pivot around between a standby position (Ia) in which the indicator (I) overlaps one face of the desiccant pack (D) and an in-use position (Ib) in which it overhangs outside from one end edge (De) of the desiccant pack (D)), with the pivot center in the bonding portion or the vicinity thereof. This enables the humidity indicator to overlap the desiccant pack in the standby position when it is in an unused state, and after being enclosed within a packaging bag the humidity indicator and the desiccant pack can be kept as far away from each other as possible within the packaging bag, thus enabling detection of the humidity of the interior of the bag to be carried out precisely and appropriately.Type: GrantFiled: May 24, 2007Date of Patent: April 12, 2011Assignee: AP Tech Corp.Inventor: Yoichi Yamakawa
