PURPOSE:To enable the easy and quick interchangeability of work units by arranging a plurality of intermediate shafts corresponding to the work units around a driving shaft located at the center of a fixed table, and connecting each intermediate shaft to the driving shaft and the input shaft of each work unit respectively via timing belts. CONSTITUTION:A hollow support pillar 41 is erected on the center of a fixed table 5 and a driving shaft 45 is passed through the pillar 41. A bearing block 46 is projected from the upper end of the support pillar 41, support holes 47 corresponding in number to each work unit 6 are formed thereon and intermediate shafts 48 are inserted therein. The driving shaft 45 and each intermediate shaft 48 are interlocked with each other via a timing belt 53 extended on pulleys 52 and 50 at the upper ends of said shafts 45 and 48. Also, a pulley 57 at the lower end of the intermediate shaft 48 is connected to the input shaft pulley 58 of the work unit 6 via a timing belt. According to the aforesaid constitution, various types of work units can be easily exchanged.
