A creasing/slotting device is provided which makes it possible to form slots at ends of creases with the axes of the slots aligned with the respective creases. A plurality of pairs of upper movable frames 6and lower movable frames 7are arranged perpendicularly to the sheet feed direction. An upper feed screw mechanism 10having a threaded shaft 11for individually moving each of the upper movable frames 6, a lower feed screw mechanism 14having a threaded shaft 15for individually moving each of the lower movable frames 7are provided, and a synchronizing mechanism 20is provided between the threaded shaft 11and 15to synchronize the rotations of the threaded shafts. A pair of creasing rolls 51and 52for forming creases are supported by each vertically opposed pair of the movable frames 6and 7, respectively. Downstream of the pair of the creasing rolls 51and 52, a pair of rotary cutters 71and 72are supported by the pair of movable frames 6and 7. By synchronously rotating the threaded shafts 11and 15, the pair of movable frames 6and 7are moved simultaneously in the same direction by the same distance, so that it is possible to position the pair of creasing rolls 51and 52and the pair of rotary cutters 71and 72without changing the relative position therebetween. This prevents misalignment between the axes of the slots and the respective creases.
