Patent number: 9285708Abstract: An image forming apparatus includes a toner case, an opening/closing member, a lever member, a drive transmission mechanism, and a biasing member. The toner case is attached to an apparatus main body. The opening/closing member opens and closes a toner discharge outlet formed in the toner case. The lever member is operated between a first operation position and a second operation position for the opening/closing member to be moved to a closing position corresponding to the first operation position or to an opening position corresponding to the second operation position. The drive transmission mechanism transmits, to the opening/closing member, a driving force input by operation of the lever member. The biasing member biases the opening/closing member toward the closing position when the lever member is at the first operation position, and biases the opening/closing member toward the opening position when the lever member is at the second operation position.Type: GrantFiled: June 19, 2015Date of Patent: March 15, 2016Assignee: KYOCERA Document Solutions Inc.Inventor: Atsuhiro Wakimoto

Patent number: 9182702Abstract: An image forming apparatus includes a toner container. The toner container includes an opening/closing portion and an operation portion. The image forming apparatus includes a drive transmission portion and a detection portion. When the lever of the operation portion is swingingly operated, the operation driving force of the operation is transmitted to the opening/closing portion via a first rotation portion and a second rotation portion. This allows a shutter cylinder to move from a closing position to an opening position. In addition, when the second rotation portion is rotated, a detected bar of the detection portion moves from a second position to a first position. The detection portion detects that a toner discharge outlet is opened, by detecting that the detected bar has moved to the first position.Type: GrantFiled: February 9, 2015Date of Patent: November 10, 2015Assignee: KYOCERA Document Solutions Inc.Inventor: Atsuhiro Wakimoto

Patent number: 8983343Abstract: An image forming apparatus includes a toner case and an installed part. The toner case includes a discharge port discharging a toner. To the installed part, the toner case is detachably installed. On the circumference of the toner case, a locking piece is provided. The installed part includes a locking member covering at least a part of the circumference of the toner case. The locking member has an insertion depression, an engaging piece and a biasing member. The insertion depression is arranged along an installing direction of the toner case and is capable of insertion of the locking piece. The engaging piece moves between a protrusive position protruded to the insertion depression at predetermined length and a withdrawn position withdrawn further than the protrusive position from the insertion depression in intersecting directions with the installing direction. The biasing member biases the engaging piece to the protrusive position side.Type: GrantFiled: April 22, 2013Date of Patent: March 17, 2015Assignee: KYOCERA Document Solutions Inc.Inventor: Atsuhiro Wakimoto

Patent number: 8977170Abstract: An image forming apparatus includes a toner case containing a toner and an installed member in which the toner case is installed. The toner case has a case main body in which rotating members are installed, and a following coupling. The case main body has a discharge port discharging the toner. The following coupling is connected to the rotating member and has a pressured part. The installed member has a drive coupling and a drive source rotating the drive coupling. The drive coupling is linked to the following coupling and has a pressuring part. The drive coupling and following coupling are rotated in the same rotation direction around the same rotation axis by pressuring the pressured part by the pressuring part. The pressured part is provided so as to come close to the rotation axis from an upper stream side to a lower stream side in the rotation direction.Type: GrantFiled: September 20, 2013Date of Patent: March 10, 2015Assignee: KYOCERA Document Solutions Inc.Inventor: Atsuhiro Wakimoto
