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 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: Apparatus for the treatment of a wiping solution, which includes ink flocculation apparatus for flocculating ink contained in a used wiping solution by the addition of a flocculant to the used wiping solution; solid-liquid separation apparatus for separating, into sludge and a filtrate, the used wiping solution containing the ink which is flocculated by the ink flocculation apparatus through filtration of the used wiping solution; distilled water production apparatus for producing distilled water and a concentrated solution through heating of the filtrate which is separated by the solid-liquid separation apparatus; water recycling apparatus for recycling the distilled water which is produced by the distilled water production apparatus as a raw material of a wiping solution; and post treatment apparatus for separating the concentrated solution into steam and a solid residue through heating of the concentrated solution which is produced by the distilled water production apparatus.
