Abstract (en)
[origin: EP0780198A1] A sheet cutting apparatus is composed of a guide rail (21c) extending in a predetermined direction, a fixed blade (22) arranged in parallel with the guide rail (21c), a rotary blade (27) for rotating in contact with the fixed blade (22), a blade carriage (24) for rotatably supporting the rotary blade (27) and moving along the guide rail (21c), together with the rotary blade (27), and a driving mechanism (25, 30, 31) for driving the blade carriage (24) and the rotary blade (27) to cut a sheet supplied to the fixed blade (22). Particularly, the driving mechanism includes a single spherical rolling element (30) for rotating in contact with the guide rail (21c) and the rotary blade (27), and a rolling element supporting member (31) for supporting the spherical rolling element (30) within a space where the spherical rolling element (30) pushes a point of a rotary blade (27) plane except for a first straight line which extends in the predetermined direction through a center of the rotary blade (27) and a second straight line which extends in a direction perpendicular to the first straight line through the center of the rotary blade (27). <IMAGE>
