Zusammenfassung:	A sheet material cutting mechanism for cutting sheet materials two rotary blades and a mechanism for pressing down a sheet material to be cut. When the motor is started, a screw shaft 2 rotates, and a rotary blade assembly 4 starts to move to the right in FIG. 1 . Then, the roller 12 rotates by friction with a frame 1, and a first rotary blade 10 rotates by the rotation of a roller. At the same time, a second rotary blade 20 also rotates by the frictional force generated between the rubber roller 22 and the frame 1. The sheet material, fed into the sheet material receiving portion 17, is pressed by the rubber roller 22 against the surface 5 of the frame 1 immediately before cutting to prevent lifting or bending of the sheet material, thereby producing satisfactory cutting of the sheet material.
