Abstract: An envelope processing apparatus for enclosing an enclosure in an envelope includes an envelope conveyance path, an enclosure supplier, an envelope supplier, a flap opener, and an envelope stacker. The envelope conveyance path extends in a substantially vertical direction to convey the envelope. The enclosure supplier supplies the enclosure to the envelope via the envelope conveyance path. The envelope supplier supplies the envelope to the envelope conveyance path, The flap opener opens a flap portion of the envelope between the envelope supplier and the envelope conveyance path. The envelope stacker stacks the envelope ejected from the envelope conveyance path.

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.

The generation unit generates the correction data corresponding to a light source not included in the first number of the light sources by carrying out interpolation processing while using at least two reference images out of the first number of the reference images.
