Abstract
By moving the printing head of a printing unit to a position outside the printing area, a paper stop is pivoted into the paper transport path and, by lowering the printing head, a gap is opened both between the printing head and printing abutment and between the paper pressure rollers, the coupling of the printing head to the paper pressure rollers in relation to the lowering movement simultaneously effecting adjustment of the printing head gap.
Claims17
A printing device for transporting a piece of paper in a transport direction and along a predetermined transport path that defines a plane, the printing device comprising:
- a printing head, a first lever, a first stationary bearing, a guide roller, a second bearing, a third bearing and a first guide rod,
- the printing head connected to the first lever, the first lever and printing head being connected to the first stationary bearing for pivotal movement about the first stationary bearing, the first stationary bearing having a first axis that is parallel to the plane of the transport path and perpendicular to the transport direction,
- the first lever also being connected to the guide roller by the second bearing having a second axis that is parallel to the first axis,
- the first lever further being connected to the third bearing, the third bearing being disposed between the first stationary bearing and the second bearing, the third bearing having a third axis that is parallel to the first axis and the second axis whereby movement of the guide roller in a direction perpendicular the plane of the transport path results in movement of the printing head in the said direction perpendicular to the plane transport path but to a lesser degree,
- the printing head also being mounted to the first guide rod, the first guide rod extends perpendicular to the transport path, the printing head being movable along the guide rod in a lateral direction away from the transport path.
A printing device for transporting a piece of paper in a transport direction and along a predetermined transport path that defines a plane, the printing device comprising:
- a printing head, a guide rod, a pivoting lever and a paper stop,
- the printing head disposed parallel to the transport path,
- the printing head being mounted to the guide rod that extends perpendicular to the transport path, the printing head being movable along the guide rod in a lateral direction away from the transport path,
- the printing head engaging the pivoting lever when the printing head is moved along the guide rod and laterally away from the transport path, the pivoting lever engaging the paper stop when the printing head is moved along the guide rod and laterally away from the transport path resulting in movement of at least a portion of the paper stop into the transport path.

- the printing head also being mounted to the first guide rod that extends perpendicular to the transport path, the printing head being slidable along the first guide rod in a lateral direction away from the transport path,
- the printing head engaging the pivoting lever when the printing head is moved along the first guide rod and laterally away from the transport path, the pivoting lever engaging the paper stop when the printing head is moved along the first guide rod and laterally away from the transport path resulting in movement of at least a portion of the paper stop into the transport path.
