Abstract
A paper cutting machine is provided for cutting a plurality of sheets of paper stacked one upon another on a table, including a paper support () that moves down from above along longitudinal beams () and a cutter () that moves up from below in an oblique direction. The paper support () has a rest () for receiving a cutting edge of the cutter. The rest () is moved in a predetermined pitch whenever the number of strokes of the cutter () reaches a predetermined number. Accordingly, even when the cutting edge of the cutter cuts into the rest and becomes deteriorated, the cutter need not be exchanged immediately, the life of the rest can be lengthened and the number of sheets cut before exchange is necessary can be drastically improved.
