PURPOSE:To reduce the suspension of a machine due to failures in suction, by turning a turret head to suck up electronic components with other transfer head whenever failure is detected in sucking up them among those held by suction with a specific transfer head. CONSTITUTION:A head A is used to suck up and electronic component 9 while a head B is set in the direction of suction angle T1. A head F is set in the direction of mounting angle T2 with a second angle setter and further, indexed. Mounting is performed by repeating this operation. But to cope with defective suction, the following action with be taken. Any sticking of an electronic component 9 or failure in sucking it 9 is detected with a detector 11 and a turret head 1 does an indexing with a controller based on the output signal thereof and uses the transfer head B to suck up the same electronic component 9 from a feeder 10 again as shown by the drawing (b). Thus, the operation is returned to the normal and the repetition of the same action is performed continually. In case of failure in suction, the feeder 10 feeds by a pitch U to supply the subsequent electronic component instead.
