Abstract: A handler includes a table which supports an electronic device, a socket which is arranged to face the table, and a transport mechanism which transports the electronic device. The transport mechanism includes a contact head having a lead press with a recess for storing the electronic device, and a chuck sleeve which extends through the lead press, is arranged relatively movable from the lead press in a direction in which the chuck sleeve extends, and chucks the electronic device, an elevating mechanism which moves the contact head between the table and the socket, a pivot mechanism which pivots the contact head within the vertical plane, and a control unit which controls chucking and release of the electronic device by the chuck sleeve, and vertical movement and pivot of the contact head.
