The apparatus includes an embroidery frame driving unit having the embroidery frame to fix an object and placed on a table of the sewing machine, and a Y-directional movement mechanism to move the frame driving unit in the Y-direction. The Y-directional movement mechanism includes a fixed frame having gear teeth, and an embroidery frame driving unit installed on the fixed frame engaged with the gear teeth to reciprocate the frame driving unit in the Y-direction.
