To obtain a reversing switch device having a simple structure with which working time is short by using a semi-automatic system.

A regulating shaft 26 is provided in parallel with a drum axis of a drum group and in a movable and rotatable manner in the axial direction. By the movement of the regulating shaft 26 in the axial direction, operating conditions of cut and connection of a coupling device, gripper phase regulation, and paper size regulation are set. By the rotation of the regulating shaft 26, a torque necessary for each regulating work is generated.
