Abstract
The conveying apparatus has drive rollers and driven rollers that are opposing each other with the conveying path put between them. The driven rollers are in the dual layers structure comprising rubbers and sponges and are arranged rigidly to the drive rollers that are rigidly arranged at a prescribed center distance. When postal matters are rushed into the nips, the driven rollers are elastically deformed to follow the postal matters.
Claims23
A paper-like material conveying apparatus comprising:
- a drive roller which is given with a driving force, rotated and driven;
- and
- a driven roller arranged rotatably following the rotation of the drive rollers, the driven roller including a first layer formed with a solid elastic material that is in contact with the drive roller and a second layer formed with a foam elastic material that is formed at the inside from the first layer,
- wherein paper-like materials conveyed into the nip between the drive roller and the driven roller are pinched, conveyed and carried out.

A paper-like material conveying direction switching apparatus comprising:
- a drive roller which is given with a drive force, rotated and driven in both the forward and reverse directions;
- and
- a driven roller arranged rotatably following the rotation of the drive rollers, the driven roller including a first layer formed with a solid elastic material that is in contact with the drive roller and a second layer formed with a foam elastic material that is formed at the inside from the first layer,
- wherein paper-like materials in non-uniform thickness conveyed into the nip between the drive roller and the driven roller are pinched, conveyed and stopped and then, the drive roller is counter-rotated and the paper-like materials are carried out in the reverse direction.

A paper-like material stamping apparatus comprising:
- a cylindrical stamp having a convex plate on the outer surface, which is given with a driving force and rotates;
- an ink supply portion to supply ink to the outer surface of the cylindrical stamp;
- and
- a platen roller arranged on the outer surface of the cylindrical stamp in the non-contact state via a prescribed gap, the platen roller including a first layer formed with a solid elastic material and a second layer formed with a foam elastic material that is formed at the inside from the first layer, and the platen roller being given with a driving force and rotated in the same direction as the cylindrical stamp,
- wherein a mark is stamped on the surfaces of paper-like materials in non-uniform thickness carried into the gap by contacting and rotating the cylindrical stamp thereon.
2 more elements
A paper-like material conveying apparatus comprising:
- plural drive rollers to contact the same surfaces of paper-like materials taken out on a conveying path and rotate in the conveying direction at the same peripheral velocity;
- and
- plural driven rollers rigidly arranged in contact with plural drive rollers rotatably following the rotation of the drive rollers, respectively through the conveying path and allow to accept paper-like materials conveyed into nips between the driven rollers and the opposed drive rollers by elastically deforming and rotate independently each other.
A paper-like material conveying direction switching apparatus comprising:
- plural drive rollers which contact the same surfaces of paper-like materials taken out on a conveying path and rotate in the same direction at the same peripheral velocity;
- and
- plural driven rollers which are arranged rigidly to contact the plural drive rollers through the conveying path, rotatably following the rotation of the drive rollers, allow to accept paper-like materials to the nips between the driven rollers and the opposed drive rollers by elastically deforming and rotate each other independently,
- wherein paper-like materials conveyed into the plural nips are conveyed while pinched and stopped and then, the plural drive rollers are counter-rotated and the paper-like materials are carried out in the reverse direction.
