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

A book binding system for a saddle-stitched bound booklet comprises a sheet feeding section () feeding sheets or sets of sheets (P) one by one, a sheet folding section () sequentially receiving a sheet or a set of sheets (P) from the sheet feeding section () and folding the sheet or the set of sheets (P) along the center line thereof, a sheet stacking section () stacking the sheet or the set of sheets (P) folded by the sheet folding section () in such a manner that the folded sheets or the folded sets of sheets are aligned with each other with respect to the fold lines thereof, a sheet stitching section () receiving a stack of the sheets or the sets of sheets (P') from the sheet stacking section () each time the predetermined number of the sheets or the sets of sheets (P) are stacked in the sheet stacking section, and stitching the stack of the sheets or the sets of sheets (P&#x2032;) at the fold line thereof, and a control section () controlling operation of the sheet feeding section (), the sheet folding section () and the sheet stitching section ().
