Abstract
A thread cutting device of a sewing machine is provided. The thread cutting device cuts a thread extending between a horizontal shuttle and a throat plate of the sewing machine. The thread cutting device includes a fixed blade, a first thread catcher, a second thread catcher, a driving assembly which moves the first and second thread catchers such that the first thread catcher catches the thread before the second thread catcher catches the thread and pulls the thread toward the fixed blade to cut the thread, and a guide member disposed between the first thread catcher and the driving assembly. The guide member guides the first thread catcher from an advanced position to a thread catching position to catch the thread, and further guides the first thread catcher from the thread catching position to a standby position to turn the first thread catcher toward the fixed blade.
