PROBLEM TO BE SOLVED: To ensure the smooth and quick data transmission and data processing by providing a common data bus for working position control and yarn dust prevention in order to communicate with a central processor. SOLUTION: A processor 14 is connected to a multiple connecting device 19 through a line 18. A number of another spinning positions are similarly connected to the multiple connecting device 19 through lines 20. The multiple connecting device 19 is connected to the central processor 21 of a rotor spinning machine through a data bus 24. A plurality of processors 14, 14' is collected to one multiple connecting device 19, 19', whereby a difficulty as might be caused, for example, in the connection of working positions exceeding 300 to only one data bus can be avoided. The data bus 24 is constituted as a CAN bus, so that a data block can be extremely quickly supplied to each multiple connecting device 19, 19'. Since the number of connection parts of the data bus 24 is reduced, the assembling of an amplifier can be omitted.
