Abstract
A sheet separation device includes a sheet separation unit, a displacement detector, a displacement adjuster, and a controller. The sheet separation unit performs a sheet separating operation and a sheet inserting operation. The displacement detector detects a displacement amount of the two-ply sheet when the two-ply sheet is displaced in a width direction of the two-ply sheet and detects a displacement amount of the inner sheet. The displacement adjuster adjusts the displacement of the two-ply sheet in the width direction before the sheet separating operation, based on the displacement amount of the two-ply sheet in the width direction detected by the displacement detector. The controller causes the displacement adjuster to adjust relative positions of the two-ply sheet and the inner sheet between the sheet separating operation and the sheet inserting operation, based on the displacement amount of the inner sheet in the width direction detected by the displacement detector.
