PURPOSE:To realize a smooth high speed operation and a high speed operation of the whole body of the device, by combining a crank mechanism, a cam having a cam groove including a circular arc, and a link mechanism. CONSTITUTION:This signature carrying out device is composed of a carnk mechanism 11 synchronized to a converyng chain to carry out a folding copy book, a cam 12 to limit the tip of the rod 11 a of the crank mechanism 11 by its cam groove 12b including a circular arc through a cam follower 12a, a link mechanism 13 to rotate a driving shaft 11 a regularly and reversely by the cam follower 12a, and a thrust blade 16 connected to the driving shaft 11a through a parallel link 15. The cam 12 has the cam groove 12b with a circular arc form making the length of a link 13a as its radius, and can thrust up the thrust blade 16 to the upper side operating position in a specific rotating angle scope out of one rotation of the driving wheel 11c, and can reset it to the lower side waiting position. |
