Abstract
A sewing machine includes a sewing machine motor configured to generate drive power to drive a needle bar up-and-down motion mechanism and a cutting unit. The cutting unit includes a cutting needle having a distal end with a blade, and a cutting needle up-and-down motion mechanism having a first motor separate from a sewing machine motor and configured to generate drive power to move the cutting needle independently of the needle bar up-and-down motion mechanism. A cut is formed by the blade as a result of up-and-down motion of the cutting needle while the cutting needle is held in a manner such that an extending direction of the cutting needle corresponds with an extending direction of the needle bar. The cutting unit further includes a cutting needle rotating mechanism configured to rotate the cutting needle about a central axis line of the cutting needle directed to the extending direction.
