Abstract

Abstract A register mechanism for a printing printer is capable of correcting shift and skew of sheets of paper (1) which are conveyed by a plurality of paper conveying passages and of temporarily stopping the conveyance of the papers (1) while they are brought into register with a toner image. The register mechanism includes: oblique belts (4, 5) provided in each of the paper conveying passages; a guide plate (6, 7) for restricting inclination of the paper (1) located on the oblique belt (4, 5); and pivot members (8, 8a, 8b) for correcting skew of the papers (1), which is located at a joined portion of the paper conveying passsages where the sheets of paper (1) whose shift has been corrected by the respective guide plates (6, 7) are joined, and downstream of the conveying passages at a distance shorter than the length of the paper (1) in the conveying direction from the end of the guide plates (6, 7).
