PURPOSE:To obtain a device which is capable of confirming efficiently a collet contact without manpower and protecting the collet from damage by detecting changes in an output signal of an approach sensor, grasping a contact state between a support member and a block member and controlling the drive of a transfer means based on their contacted state. CONSTITUTION:A carrier means which carries a lead frame 3 to a bonding position of a chip 5 intermittently, a collect 4 which holds the chip 5, a support member 10 which supports the collect 4 and a block member 12 which has a site in contact with the support member 10 are provided. Transfer means 25, 26 and 29 which transfer the block member 12 to the lead frame side 12, a pressing means 16 which presses the support member 10 to the contact side of the block member 12 and a proximity sensor 18 mounted to the support member 10 or the block member 12 are provided, also a control means 20 which detects changes in an output signal of the proximity sensor 18, grasps a contact state between the support member 10 and the block member 12 and controls the drive of the transfer means 25, 26 and 29 are provided. |
