Abstract: An electronically controlled sewing machine indicates which of the basic operations for the machine is possible or impossible in a readily identifiable manner to a user, thereby improving the ease of operation of the machine. A start/stop button is illuminated with steady green light, that is, a first illuminated state, when a presser foot is at a pressing position and a needle bar is within a threading possible range. When the presser foot is at a withdrawn position and the needle bar is within the threading possible range, the start/stop button is illuminated with red flicker, that is, a second illuminated state. When the presser foot is at the pressing position and the needle bar is out of the threading possible range, the start/stop button is illuminated with green flicker, that is, a third illuminated state.
