PURPOSE:To automatically change the stage of a supporting pin when changing the type of an electronic circuit board by positioning a chuck at the position of the supporting pin which becomes unnecessary by using a driving part. CONSTITUTION:When changing a stage for mounting on a printed board 8, a head 21 stores a first chuck 9 in a holding part 10, then the head 21 is mounted with a second chuck 1. The second chuck is shifted to the position of a supporting pin 2 which becomes unnecessary for the subsequent printed board 8 to pull out the supporting pin 2 by driving parts 11 and 22, then, the chuck 1 shifts to the prescribed position necessary for the subsequent printed board 8 and the supporting pin 2 is inserted. Such operation is repeated necessary times and a stage is changed according to the type of the printed board 8 of the supporting pin 2. Thus, the stage is automatically changed when changing the type of the electronic circuit board. |
