PURPOSE:To automatically rearrange backup pins with a mounting head at the time of supporting a circuit board on which parts are to be mounted with the backup pin group. CONSTITUTION:The backup pins of a board supporting section 60 support a circuit board 1. A backup pin stocker 70 is provided beside the section 60 and holds backup pins which are not required for the present time. A mounting head 30 picks up parts from parts supplying sections 14 and 15 and mounts the picked-up parts on the circuit board 1. A nozzle 33 is attached to the head 30 in a removable state and a nozzle exchanging section 40 exchanges the nozzle 33 with another nozzle 33. The section 40 also holds a backup pin attracting nozzle and, at the time of rearranging the backup pins, the head 30 performs the mounting work after exchanging the ordinary nozzle 33 with the backup pin attracting nozzle. |
