[ The adsorption pad 642 can be operated in a vacuum adsorption manner similar to the adsorption pad disposed in the inspection hand or transfer hand described above.

The inspection object BT whose inspection has been completed can be transferred by the transfer hand and disposed at a predetermined position. For example, the predetermined position may be the start position of the transfer line for transferring the inspection object BT determined to be defective. If the object to be inspected (BT) is bad, the object to be inspected (BT) can be moved along the transfer line.
