A shutter device enables access to the paper path in a single sheet printer with a first shutter (P1) which can pivot about a first pivotal axis (D2) into an open position wherein shutter stands at a distance from the paper path and uncovers an opening. A second shutter (P2) is located near the first shutter (P1). Like the first shutter, the second shutter forms, when in an operating position, a second of the guide surfaces adjacent to the section formed by the first shutter (P1), which can pivot about a second pivotal axis (D1) into an open position and increase an opening for access to the paper path when in this position. In order to support opening of the second shutter (P2), a clamping member (Z1) is also provided on the second shutter, which is prestressed when the second shutter (P2) is in the operating position.
