Disclosed herein is a cutter frame including a plurality of cutters for cutting one or more kinds of rectangular unit pieces having a relatively small size from a rectangular base material at a predetermined inclination, the cutters being mounted or formed in the cutter frame such that the cutters correspond to the rectangular unit pieces, two of the rectangular unit pieces being arranged mainly in the inclination direction such that the rectangular unit pieces are in contact with each other at one side of each rectangular unit piece, wherein, on the assumption that imaginary vertex coordinates of a leftmost end are (Ax, Ay), and imaginary vertex coordinates of a rightmost end are (Bx, By), when the rectangular unit pieces coincide with each other at a left or right side of each rectangular unit piece, vertex coordinates (B′x, B′y) of the rightmost end are greater than the imaginary vertex coordinates (Bx, By) of the rightmost end based on the imaginary vertex coordinates (Ax, Ay) of the leftmost end in an array having a higher cutting area ratio than the imaginary array. |
