Abstract: A device for conveying sheet-like material between a driven roller and a counter-pressure roller is disclosed. The device also includes opposing guide plates that form a channel for feeding the sheet-like material to the nip between the two rollers. At least one of the rollers includes a channel-like recess into which its associated guide plate extends.

Abstract: 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.

Abstract: An active switching mechanism is used for diverting paper sheets from a first area (A) to either possible paths (ab or ac). The sheets along the first path (ab) can be directly conveyed to a second area (B), and the sheets along the second path (ac) can be directed through a passive switching mechanism (4) to a third area (C), the direction of the moving sheets being reversed through a reversing mechanism, thereby enabling said sheets to be conveyed in the reverse direction from the third area (C) along a third path (cb) to the second area (B), using a passive switching device (4).
