Abstract: A perforator configured to perforate a sheet includes a first frame and a blade. The first frame includes a first main face having a first hole, and is provided under a transport path of the sheet. The blade is moved into the first hole to perforate the sheet transported in the transport path. A bending strength of the first main face in a vertical direction with respect to the transport path of the sheet is smaller than a bending strength of the first main face in a parallel direction with respect to the transport path of the sheet.
