ABSTRACT:
Bobbin case containing a lower thread bobbin mounted in a rotary hook of a sewing machine is exchanged for a new bobbin case by the bobbin case being transferred between the rotary hook and a bobbin stock section provided apart from the rotary hook. Transfer mechanism reciprocatively transfers a bobbin grasping device, grasping a bobbin case at a distal end portion of a chuck section, between the rotary hook and the bobbin stock section. In a predetermined position of a transfer stroke of the bobbin grasping device, an orientation change mechanism changes the orientation of the chuck section, being transferred toward the rotary hook, so that the chuck section faces toward the rotary hook, and changes the orientation of the chuck section of the bobbin grasping device, being transferred toward the bobbin stock section, so that the chuck section faces toward the bobbin stock section.
