Abstract: 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.

Abstract: 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.

Abstract: An envelope processing apparatus for enclosing an enclosure into an envelope conveyed to an enclosing position includes a conveyance roller that conveys the envelope to the enclosing position. A first envelope length calculator calculates a first envelope length of the envelope in an envelope conveyance direction in which the envelope is conveyed in a close state in which a flap of the envelope closes. A flap opener opens the flap while the conveyance roller conveys the envelope. A second envelope length calculator calculates a second envelope length of the envelope in the envelope conveyance direction in an open state in which the flap opens. A controller calculates a flap length of the flap in the envelope conveyance direction based on the first envelope length and the second envelope length. The controller controls enclosing of the enclosure into the envelope based on the flap length.

Abstract: An envelope processing apparatus includes a flap opener, a first envelope detector, a second envelope detector, and circuitry. The flap opener opens a flap of an envelope during conveyance of the envelope in an envelope conveyance passage in which the envelope is conveyed to an enclosing position. The first envelope detector detects the envelope at a position upstream from the flap opener in a conveyance direction of the envelope. The second envelope detector detects the envelope at a position downstream from the flap opener in the conveyance direction. The circuitry causes the flap opener to execute an opening operation of the flap of the envelope conveyed to the enclosing position and causes the flap opener to execute the opening operation of the flap again when an opening-and-closing state of the flap determined based on detection results of the envelope by the first and second envelope detectors is abnormal.

Abstract: An enclosing device to insert an enclosure into an envelope conveyed to an enclosing position includes an envelope conveyor and an enclosing unit. The envelope conveyor conveys the envelope to the enclosing position. The enclosing unit opens a frontage of the envelope such that the enclosure is inserted into the envelope that has reached the enclosing position and includes an opening amount adjuster to adjust an opening amount of the frontage when the enclosure is inserted into the envelope. The opening amount adjuster adjusts the opening amount, depending on a flap length and a body length. The flap length is a length of a flap of the envelope in a conveyance direction in which the envelope is conveyed to the enclosing position. The body length is a length of a body of the envelope in the conveyance direction.

Abstract: An envelope processing apparatus that inserts an enclosure into an envelope includes an envelope conveyor, a flap opener, an enclosure pusher, and circuitry. The envelope conveyor extends in a vertical direction and conveys the envelope to an enclosing position via an envelope conveyance passage as a passage in which the envelope is conveyed. The flap opener opens a flap of the envelope. The enclosure pusher pushes the enclosure toward an opening of a body of the envelope conveyed to the enclosing position with the flap open. The circuitry changes a pushing amount of the enclosure into the envelope and adjusts the pushing amount based on the opening of the body of the envelope within a specified range from an inside to an outside of the body of the envelope.

Abstract: An envelope processing apparatus inserts an enclosure into an envelope and includes a first conveyor, a first ejector, a second conveyor, a second ejector, and circuitry. The first conveyor conveys the enclosure to an enclosing position. The envelope in which the enclosure is enclosed is ejected to the first ejector. The second conveyor conveys the envelope to the enclosing position via an envelope conveyance passage extended in a substantially vertical and up-and-down direction and conveys the envelope in which the enclosure is inserted to the first ejector. The second ejector is separate from the first ejector. The enclosure is ejected to the second ejector. The circuitry controls a conveyance operation of the first conveyor and the second conveyor.

Abstract: An enclosing apparatus for enclosing an enclosure into an envelope at an enclosing position includes a conveyance roller that conveys the envelope to the enclosing position and an envelope conveyance path through which the envelope is conveyed. An enclosing support is disposed in the envelope conveyance path and supports enclosing of the enclosure into the envelope. The enclosing support retracts a flap of the envelope from the envelope conveyance path while the conveyance roller conveys the envelope to the enclosing position.

Abstract: A sheet processing device sandwiches a sheet-shaped medium in a two-ply sheet in which two sheets are overlaid and partially bonded. The sheet processing device includes a separator, a conveyor, and a switching member. The separator separates the two sheets of the two-ply sheet. The conveyor is disposed downstream from the separator in a sheet conveyance direction and conveys the two-ply sheet. The switching member is disposed downstream from the conveyor in the sheet conveyance direction. The switching member switches a conveyance path of the two-ply sheet to convey the two-ply sheet to a fixing path on which fixing processing is performed on the two-ply sheet or a non-fixing path on which no fixing processing is performed on the two-ply sheet.

Abstract: A sheet stacking apparatus includes an ejector, a stacker, a wall, and an upper surface detector. The ejector ejects a sheet, and the stacker stacks the sheet ejected from the ejector. The wall contacts a trailing end of the sheet ejected from the ejector in an ejection direction to align the sheet. The upper surface detector detects an upper surface on a trailing end side of the sheet stacked on the stacker in the ejection direction. When the sheet moves toward the wall, the upper surface detector moves from a home position in which the upper surface detector detects the upper surface of the sheet to a retracted position in which the upper surface detector does not contact the sheet moving toward the wall.
