Abstract
A sheet processing device includes a conveyor, a rotator, a separator, and control circuitry. The conveyor conveys a sheet-shaped medium into a two-ply sheet in which two sheets are overlaid and partially bonded, and includes a drive roller and a driven roller. The rotator winds the two-ply sheet. The separator separates the two sheets of the two-ply sheet. The control circuitry causes the conveyor to convey the two-ply sheet in a winding direction to wind the two-ply sheet around the rotator to generate a space between the two sheets, and causes the separator to insert into the space between the two sheets to separate the two sheets. The drive roller and the rotator are disposed on a same side with respect to a sheet conveyance passage of the two-ply sheet, and the driven roller and the rotator are disposed on opposite sides with respect to the sheet conveyance passage.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
