Abstract
Disclosed herein is a sheet cutting apparatus suitable for use in pre-cutting off an edge portion of a sheet of a large area. The apparatus comprises a sheet transfer mechanism; a first rotating shaft rotated through the torque of a motor; a turnable frame attached angularly movably along a circular orbit to the first rotating shaft; a second rotating shaft supported rotatably by the turnable frame so as to extend in a radial direction of the circular orbit of the turnable frame and meshed with the first rotating shaft to rotate therewith; a cutter blade and a backing blade, both, rotated by the torque of the second rotating shaft; and a turn control section for angularly moving reciprocally the turnable frame between an initial position at which the surface of revolution of the cutter blade and backing blade extends in a direction transferring a sheet and a separated position at which the cutter blade and backing blade turn aside from the transfer path of the sheet.
