Patent ID: 11459204

Abstract:
A sheet folding device includes a folding rollers pair, a folding blade, a movable guide, and a driving mechanism. The folding rollers pair includes a first roller and a second roller, and causes a sheet conveyed in a first conveyance direction to pass through a first nip area between the rollers. The folding blade is selectively disposed in a folding position and in a retracting position. The movable guide can reciprocate between a covering position covering the second roller disposed downstream of the first roller in the first conveyance direction and the first nip area and a non-covering position exposing the second roller and the first nip area. The drive mechanism disposes the folding blade in the folding position while disposing the movable guide in the non-covering position, and disposes the folding blade in the retracting position while disposing the movable guide in the covering position.
