Abstract
A sewing machine includes a needle bar that is equipped with a sewing needle at a lower end of the needle bar, a presser bar that is equipped with a presser foot at a lower end of the presser bar, which holds down a work cloth, a sewing machine motor which is a driving source that drives the needle bar in an up and down direction, and a switching device that switches between a normal mode in which the needle bar is driven in the up and down direction to form stitches and a practice mode in which the sewing machine is operated in a condition where at least the needle bar is not driven.
