Publication number: 20240075767Abstract: An envelope processing apparatus conveys an envelope to an enclosing position and encloses an enclosure on which specific information is formed at a formation position. The enclosing device includes: an envelope conveyor to convey the enclosure to the enclosing position to insert the enclosure into the envelope; a sensor to acquire, as an image, a structure of the envelope during conveyance, and acquire transparent-portion information indicating a position of a transparent portion in the envelope; an envelope holder to hold the envelope in a state in which the enclosure is insertable; and control circuitry to output position adjustment information for adjusting a position of the envelope in a width direction of the envelope at the enclosing position or a position of the specific information in a conveyance direction of the envelope, based on relative positions between the formation position of the specific information and the position of the transparent portion.Type: ApplicationFiled: September 5, 2023Publication date: March 7, 2024Applicant: Ricoh Company, Ltd.Inventors: Shingo YOSHIZAWA, Michitaka SUZUKI, Nobuyoshi SUZUKI, Yuusuke SHIBASAKI, Takahiro MATSUDA, Atsushi SHINODA, Takahiro WATANABE, Takuya MORINAGA

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
