A button sewing machine allows simultaneous sewing of both a stay button and a surface button to a workpiece and conducts button-neck-wrapping by inclining both buttons with a workpiece. A needle is arranged to travel between an upper needle bar spindle and a lower needle bar spindle, being received by each spindle alternately per each needle stroke, such that buttons are sewn in a manner closely simulating 'hand' sewing. A worktable is arranged to move in both the X and Y directions in accordance with the button hole pitch distance in synchronization with the up and down motion of the needle.
