Patent number: 11919325Abstract: An enclosing-sealing apparatus includes a flap opener that opens a flap of an envelope while the envelope is conveyed to an enclosing position. A first envelope detector is disposed upstream from the flap opener in an envelope conveyance direction and detects both ends of the envelope in the envelope conveyance direction. A second envelope detector is disposed downstream from the flap opener in the envelope conveyance direction and detects both ends of the envelope in the envelope conveyance direction in an open state in which the flap opens. A controller determines the open state of the flap based on a first detection result sent from the first envelope detector and a second detection result sent from the second envelope detector. The controller performs troubleshooting for enclosing the enclosure into the envelope if the controller determines that the open state of the flap is faulty.Type: GrantFiled: April 15, 2022Date of Patent: March 5, 2024Assignee: Ricoh Company, Ltd.Inventors: Akira Kunieda, Michitaka Suzuki, Shinji Asami, Nobuyoshi Suzuki, Yuusuke Shibasaki, Takahiro Matsuda, Makoto Hidaka, Kazuyoshi Matsuo, Shingo Yoshizawa, Takahiro Watanabe, Takuya Morinaga
