段となつていることを特徴とする排版装置。 A printing drum, a pair of upper and lower plate discharge rollers that are arranged adjacent to the print drum and discharge used base paper from the print drum during plate discharge, and rotate the print drum in the forward direction when printing and in the reverse direction when the plate is discharged. a printing drum drive means, a plate discharge roller drive means that rotates a plate discharge roller below the plate discharge roller away from the print drum during printing and in contact with the plate discharge roller; and a detection device that detects whether or not the base paper has been discharged at the time of plate discharge. In the printing press, there is provided a control means for controlling the operation of the printing drum drive means and the plate discharge roller drive means, and when a detection signal is not inputted from the detection means at the time of plate discharge, the control means controls the operation of the printing drum. A plate discharging device characterized in that the plate discharging device is a control means that operates a drive means to rotate the printing drum in the forward direction again and then in the reverse direction.
