PURPOSE:To make the backup pin supporting level of a backup pin base coincident with that of a backup pin stocker and to simplify a backup pin mounting head which executes an automatic replantation in structure by a method wherein a movable stopper which limits the ceiling of the backup pin base is provided to a board supporting device. CONSTITUTION:A pad 43 of a movable stopper 39 is made to start moving by the protrusion of a rod 42 of an air cylinder 41. A backup pin stocker 60 is made to stop ascending when a level setting block 45 bears against a bearing 51. Concurrently, a backup pin base 25 is made to stop climbing before reaching to the ceiling specified by a gauge when the pad 43 bears against a block 45. At this point, the backup pin supporting level of the backup pin base 25 is coincident with that of the backup pin stocker 60. A backup pin mounting head on standby on a required backup pin 26 is made to start moving to replant the backup pin 26 supported by the backup pin base 25 in a position correspondent to a following board. |
