A lower guillotine cutter blade ( 2 ) is mounted to a frame ( 1 ). A guillotine cutter-blade holder ( 3 ) holds an upper guillotine cutter blade ( 4 ) and vertically reciprocates with respect to the lower guillotine cutter blade ( 2 ). Rods ( 6 ) are vertically slidably mounted to the guillotine cutter-blade holder ( 3 ). A pressing plate ( 5 ) is secured to the lower ends of the rods ( 6 ). Springs ( 7 ) are fitted around the rods ( 6 ) between the guillotine cutter-blade holder ( 3 ) and the pressing plate ( 5 ) for downwardly elastically biasing the rods ( 6 ) so that the heads ( 6 a) of the rods are kept abutted against the guillotine cutter-blade holder ( 3 ). In a cutting operation, after the pressing plate ( 5 ) is brought into abutment with a batch of paper ( 20 ), the guillotine cutter-blade holder ( 3 ) is further downwardly moved, thereby causing the lower and upper guillotine cutter blades ( 2 and 4 ) to cut the batch of paper ( 20 ) and also causing the heads ( 6 a) to upwardly protrude from the guillotine cutter-blade holder ( 3 ). At this time, a sensor ( 8 ) mounted to the guillotine cutter-blade holder ( 3 ) detects the distance to the heads ( 6 a). A thickness measuring element ( 27 ) determines the thickness of the batch of paper ( 2 ) on the basis of the detection signal.
