PROBLEM TO BE SOLVED: To obtain an apparatus constituted so that a transverse creasing roller selectively creases a sheet in a transverse direction as the sheet is moved relative to a frame and longitudinal creasing rollers selectively crease the sheet in a longitudinal direction. SOLUTION: An operator 50 has a conical end part selectively entering and retreating with respect to creasing rollers 39, 40 and extended so that the conical end part is selectively engaged with the holes in respective creasing roller mechanisms 39, 40. The extension of the operator displaces a member provided with a hole 51 to selectively release the engagement of a brake so that a feed member and the longitudinal creasing roller 40 can be integrally moved from one point to other point. The operator 50 is pulled out at a desired position and the brake is again engaged and, thereafter, the longitudinal creasing roller 40 is held to a desired position with respect to a frame.
