Definitions

  • the plate-shaped upper carriage 4b nearly parallel to the upper surface of the lower carriage 4a is joined to the lower carriage 4a such that the upper carriage 4b is moved near to or away from the lower carriage 4a in parallel to each other by a parallel crank mechanism 8.
  • the parallel crank mechanism 8, as shown in FIG. 3, is provided in pairs on both sides of the carriage 4 and each of them has a pair of links 9a and 9b which are crossed in a shape of X and are rotatably joined at a crossing position with a pin 10a.
