<p>PURPOSE: To provide a sheet material cutting device constituted in such a way as to cut sheet material by two rotary blades put in cooperative cutting action, and provided with mechanism that can hold down the sheet material. CONSTITUTION: When a motor is operated to rotate a screw shaft 2 and a rotary blade assembly starts moving to the right, a roller 12 is rotated by frictional force with a frame 1, and a first rotary blade 10 is rotated by the rotation of the roller. At the same time, a second rotary blade 20 is also rotated by frictional force with a rubber roller 22 and a frame 1. Sheet material enters a sheet material receiving part, but at this time, the sheet material immediately before being cut is pressed to the face 5 of the frame 1 so as to be cut without floating or bending.</p> |
