Abstract

A sewing machine includes a thread take-up lever and a thread tension regulator each disposed along a predetermined needle thread passage from a thread bobbin to a needle, an arm having a front face, and a movable controller disposed in the front of the arm so as to be movable at least within a predetermined range. The movable controller does not protrude out of the front face of the arm when moved in the predetermined range. The needle thread is engaged with at least one of the thread take-up lever and the thread tension regulator when the movable controller is moved within the predetermined range while the needle thread has been drawn from the thread bobbin near to the needle substantially along the predetermined needle thread passage.
