Abstract
A sewing machine wherein a single operable button is capable of selectively performing a plurality of actions depending on the length of duration of the operation time. The machine is provided with a needle positioning device for arresting the needle at a certain predetermined position and a stitch forming system for forming a specific stitch pattern, and either of the two is actuated according to the length of duration of the operation time of the operable button. Furthermore, a forthcoming action of the machine can be varied in response not only to the length of duration of the operation time mentioned above but also to the state of the machine which can be in operation or stationary. The machine is thereby capable of performing a plurality of different actions by means of fewer operable buttons.
